With proximity readers there is no physical wear and tear on the card/tag or the reading device. No inserting of a card/tag into a reader slot or swiping of a card/tag through a reader slot is required. The card/tag is simply held up to a reader, within the reader's detection range. Refer to Figure 1 for a diagram of this process. In a proximity reader application, a continuous 125 kHz electromagnetic field is radiated from a coil inside the reader. This field is called the "excitation signal." When a card/tag is presented to a reader, a coil inside the card/tag picks up the excitation signal from the reader generating a small current in the card/tag's coil. This current powers a small integrated circuit (IC) within the card/tag that holds a unique identification number. The coil in the card/tag transmits this identification number using a 62.5 kHz electromagnetic field, one-half the value of the excitation signal. This 62.5 kHz signal acts as an analog RF carrier for the digital ID number and is called the "receive signal" as the coil in the reader receives this signal. The reader passes the signal on to the RF receiver in the controller for decoding where it is processed, error checked, and converted to a digital signal. The receiver then sends the digital signal with the ID number to the microprocessor in the controller where an access decision is made. The read range for a key tag is approximately one-half that of a card. This is due to the physical size of the coil in the tag compared to the coil in the card. Since the coil in the tag is smaller, it needs to be closer to the excitation signal to activate the IC within the tag. The bigger the coil in the card, tag, or reader, the greater the read range is likely to be. 125 KHz Door Control CARD PXL-250 Controller Microprocessor Reader TAG Receiver 62.5 KHz Figure 1 – Proximity - Principle of Operation Printing Date October-1998 01836-002 Rev. 3.1 Page 7 of 46 SYSTEM INFORMATION Proximity – Principle of Operation SYSTEM INFORMATION Technical Reference Manual – PXL-250 4,000 Feet Total Distance for Controller Network Communication RS-232 Serial Communication Direct or Via Modem PC Direct to PC (50 feet max) Modem Via Modem Modem PC Global Unlock or Auxiliary RTE-A Input Door Alarm Lock, Door Switch, RTE "A" Reader "B" Reader PXL-250 MASTER Address - 1 PXL-250 Tiger Controller Door Switch and Request to Exit Inputs General Purpose Inputs Door Lock Output Relay (3A, Form C) Door Alarm Output Relay (3A, Form C) 4 Output Relays 8 General Purpose Inputs SB-293 SATELLITE BOARD SB-293 Satellite Board May Have 8 General Purpose Inputs and 4 Output Relays Global Unlock or Auxiliary RTE-A Input Door Alarm Lock, Door Switch, RTE "A" Reader PXL-250 SLAVE Address - 3 "B" Reader PXL-250 Tiger Controller Door Switch and Request to Exit Inputs General Purpose Inputs Door Lock Output Relay (3A, Form C) Door Alarm Output Relay (3A, Form C) RS-485 Serial Communication Controller Network Figure 2 – A Basic PXL-250 Access Control Network with Options 01836-002 Rev. 3.1 Page 8 of 46 Printing Date October-1998 Technical Reference Manual – PXL-250 SYSTEM INFORMATION RS-485 Serial Communication Controller Network 1 Input can be User Configured for Auxiliary RTE - "B" 6 General Purpose Inputs Both Output Relays can be User Configured for Additional Alarm Annunciation 2 Output Relays Lock, Door Switch, RTE - "B" Door Alarm - "B" SB-293 SATELLITE BOARD Auxiliary RTE - "A" or General Purpose Input SB-293 Satellite Board May Have Second Door Control with Door Switch & Request to Exit Inputs Door Lock Output Relay (3A, Form C) Door Alarm Output Relay (3A, Form C) and 6 General Purpose Inputs 2 Output Relays Door Alarm - "A" Lock, Door Switch, RTE - "A" "A" Reader PXL-250 SLAVE Address - 2 "B" Reader PXL-250 Tiger Controller Door Switch and Request to Exit Inputs General Purpose Inputs Door Lock Output Relay (3A, Form C) Door Alarm Output Relay (3A, Form C) 4,000 Feet Total Distance for Controller Network Communication Figure 2 – A Basic PXL-250 Access Control Network with Options Printing Date October-1998 01836-002 Rev. 3.1 Page 9 of 46 SYSTEM INFORMATION Technical Reference Manual – PXL-250 Specifications Unit Dimensions • PXL-250 controller PCB − 6.75 inches high by 6.00 inches wide by 1.75 inches deep, including wiring connectors − (17.15 cm by 15.25 cm by 4.45 cm) • PXL-250 controller PCB with an SB-293 Satellite Board − 7.25 inches high by 6.00 inches wide by 1.75 inches deep, including wiring connectors − (18.45 cm by 15.25 cm by 4.45 cm) • PXL-250 controller PCB with an LCD-1 Alpha/Numeric Display − 7.70 inches high by 6.00 inches wide by 1.75 inches deep, including wiring connectors − (19.60 cm by 15.25 cm by 4.45 cm) • Enclosure − 9.70 inches high by 8.20 inches wide by 2.60 inches deep − (24.65 cm by 20.85 cm by 6.60 cm) Operating Temperature/Humidity Range • 0°F to 140°F (-18°C to 60°C) • 0% to 90% Relative Humidity, non-condensing Controller Power Requirements • 12 VDC @ 750 mA Current Draw • maximum current draw 500 mA for a controller with all options installed • 120 mA max for a PXL-250 Controller • 150 mA max for an SB-293 Satellite Board • refer to Table 1 for Reader current draw Current Draw MS-3000 50 mA MS-4000 50 mA Reader Type MS-5000 100 mA MS-7000 200 mA MS-9000 200 mA Table 1 – Reader Current Draw NOTE: If an electronic locking device (such as a magnetic lock, a door strike, or similar device) is to be driven by the same power supply as the PXL-250 controller, please ensure the power supply provides enough current to drive every device connected to that supply plus an adequate safety margin.

However, the wire gauge to use should be determined by the current draw requirements of the Wiegand device and the actual length of the cable run. A +5 VDC Wiegand device must have +5 VDC at the device (long cable runs have a voltage drop across the length of the run due to the resistance in the cable). To ensure +5 VDC is available at the device a larger gauge of wire (having less resistance) or a separate power supply at the Wiegand device may be required. Input and Output Connections • two conductor, stranded, AWG 22 or a larger gauge NOTE: The Lock Output relay may require a heavier gauge of wire depending upon the current demands of the lock and the length of the lock wiring run.

Without a quality earth ground connection, the access control system may appear to operate correctly, but will be extremely susceptible to transients and electromagnetic interference on data and power lines. An earth ground brings all electrically neutral lines to the earth’s surface potential (essentially to a zero potential) providing three primary benefits to the PXL-250 controller. 1) An earth ground protects the PXL-250 controller from electrical transients such as power surges and lightning strikes (also providing a degree of safety for an operator). 2) An earth ground provides a path to ground for electrical interference minimizing data and communication problems for the reader data and network communication lines. 3) Through a feature on the PXL-250 controller the shield for the entire RS-485 network is automatically grounded at one point on the master controller minimizing communication problems. Here are some possible sources for an earth ground. 1) 2) 3) 4) 5) copper shrouded ground rod cold water pipe (must be a metal pipe – not PVC) steel building framing member (if the building’s frame is embedded in the earth) electrical system ground (at the breaker/fuse box) telephone system ground Electromagnetic Interference Electromagnetic interference is electromagnetic energy radiated by an electrical device that may affect the operation of other electrical devices. The PXL-250 controller can be sensitive to electromagnetic interference (EMI), affecting the controller's performance. To ensure the best operating conditions for the controller, please review and consider the following suggestions. Power Supplies Switching power supplies are known sources of EMI and cannot be used as the 12 VDC source for the PXL-250 controller. Only linear, regulated power supplies should be used with any access control system using proximity readers. When installing a power supply for the PXL-250 controller, mount the power supply three feet or greater from the controller to provide a degree of isolation from EMI that may be generated by the power supply. EMI Sources Keri Systems also recommends installing the controller in low EMI areas whenever possible. Always be cognizant of sources of EMI that may affect the operation of the PXL-250 controller and install your controller away from these sources. Common sources of EMI include computer monitors, electric motors, and air conditioning and heating units. Separating Power Cables from Network and Reader Cables To prevent EMI that may be conducted between power cables and network/reader cables, Keri Systems recommends running the power cables apart from the network and reader cables. This will minimize the possible effect a voltage surge on the power cable may have on the network and reader cables. Printing Date October-1998 01836-002 Rev. 3.1 Page 13 of 46 SYSTEM INFORMATION System Cautions SYSTEM INFORMATION Technical Reference Manual – PXL-250 Transient Suppression Voltage transients are electrical surges or spikes conducted through power, input, or output lines. Transients are generated when electric devices (such as electric locking devices) are turned on or off. Transients may affect the operation of the PXL-250 controller. Because of this, transient suppression is required for the PXL-250 controller. A transient suppressor is a device added to an electrical circuit that minimizes the affects of transients. Depending upon the application, a transorb or an isolation relay provides the suppression necessary to ensure proper operation of the access control system. Under normal circumstances, a 1.5KE39C transorb must be installed across the positive and negative power lines at the electric locking device to provide the best operating conditions for the PXL-250 controller. This transorb will prevent any transients that may be generated by an electric locking device from affecting the operation of the PXL-250 controller. Two bipolar transorbs are provided with each PXL-250 for this purpose. In applications such as parking gates or turnstiles (or any application using a large electric motor), a transorb alone may not provide enough suppression; an isolation relay may be required. For ease of installation, Keri Systems offers an Isolation Relay Package (Keri Systems p/n IRP-1) which can provide suppression for the large transients generated by these types of devices. PC COM Port A COM port is a hardware device that allows a computer to communicate with external devices. To ensure proper communication between the access control system and the PC, the PC's COM port must be configured properly and be operating correctly. Most communication problems between PC and access control system are directly attributable to an improperly configured or inoperable PC COM port. Please ensure the PC COM port is working correctly before loading the Doors32™ access control software on your PC system. Keri Systems cannot be held responsible for problems using the Doors32™ access control software that are due to an inoperable COM port. To assist in verifying basic COM port operation, Keri Systems has provided a basic COM port test with the Doors32™ software package. COM port test instructions can be found with the documentation supplied with the Doors32™ software. 01836-002 Rev. 3.1 Page 14 of 46 Printing Date October-1998 Technical Reference Manual – PXL-250 PXL-250 System Installation Advance Planning A successful, easy to maintain installation requires advance planning – making sure the site has everything necessary for a successful installation and making sure that all materials are placed in easily maintainable locations that take advantage of the features the PXL-250 access control network has to offer. Utility Requirements A successful installation needs: • grounded power outlets for the PC system and for controller power supplies • dedicated analog telephone lines if communication between access control network and PC is to be done via modem – one for the host PC system and one for each master PXL-250 controller Where should the controllers be installed? Controllers should be accessible for ease of installation and ease of maintenance. Service closets may be a viable installation location. Controllers can be mounted centrally, or distributed across an access control network. Central Mounting places all controllers in one location, running lengths of cables out to each door to support the needed readers, inputs, and outputs. The benefit to central mounting is that all controllers are together in one location making it easier to maintain and secure the controllers. The drawback to central mounting is that it tends to use more cable, routing cables from the controller to each door for the reader and the necessary inputs and outputs. Accordingly, the cable costs for central mounting is higher. Also, reader cable lengths are limited to 500 feet making central mounting in a large installation difficult, if not impossible. Distributed Mounting places a controller near each door. The RS-485 network communication cable is then routed to every controller on the access control network. The benefit of distributed mounting is that less cable is needed for the reader and the necessary inputs and outputs as they are all near the controller. Only the network cable needs to be routed throughout the installation. The drawback to distributed mounting is that a location needs to be found near each door for every controller. More effort may be needed to maintain and secure the controllers. All controllers need to be mounted in environmentally suitable locations. They require protection from weather and from temperature/humidity extremes. If a PXL-250 controller is to be used outdoors, it must be installed in a watertight, weatherproof enclosure. All controllers need at least three feet of separation between the controller and the controller’s power supply. This will prevent EMI radiated by the power supply from affecting the performance of the controller. The Enrollment Reader The enrollment reader is the "A" reader on the master controller on the access control network as the Doors32™ access control software expects all card enrollment information to come from the "A" reader on the master controller. For ease of card enrollment, the enrollment reader and master controller should be physically near the host computer running the Doors32™ software. The enrollment reader can be a Keri proximity reader or a Wiegand compatible device reader. Printing Date October-1998 01836-002 Rev. 3.1 Page 15 of 46 SYSTEM INSTALLATION NOTE: In most cases, modems are not compatible with private branch exchange (PBX) telephone switching systems causing disconnection problems with the modem. For this reason, dedicated analog telephone lines are required for successful modem communication. Technical Reference Manual – PXL-250 The enrollment reader can be used at a door for access control as well as enrollment. However, during the enrollment process the door or doors assigned to the master controller become unavailable for access; these doors will remain locked throughout card enrollment. Further, if the master controller has both "A" and "B" readers, it is possible for an existing cardholder to present an already enrolled card at the B reader while an operator is enrolling a card at the A reader. In this case, the card read by the B reader will generate a "Card Already Enrolled" error message and the cardholder will not be granted access through the door because the controller/reader is in enrollment mode. For these reasons, an installer may consider reserving the master controller and one reader for card enrollment only. SYSTEM INSTALLATION Where should cables be routed? The PXL-250 controller offers flexibility in cabling options between optimizing cable costs versus controller access/convenience. However there are several things to keep in mind. When routing cables for an installation: • Do not route cables near EMI sources. Cables can act as antennas, receiving EMI that can affect controller performance. • Do not stretch cables or route them over sharp edges. • Do route cables in accessible areas whenever possible. This will make cable/system maintenance easier. When routing cables into and inside an enclosure: • Do note the location of the enclosure's knockouts (circular, removable plates on the enclosure's base plate) and remove the knockout that allows you to route your cables into the enclosure in the easiest, most direct path. • • Do not let the cables and the individual wires get tangled. Keep them neatly tied back and clear from the controller PCB. Do not stretch cables or route them over sharp edges. RS-485 Networking The PXL-250 uses a half-duplex, RS-485 communication bus. Per RS-485 industry specifications, the following rules apply when wiring the controller network communication bus. 1. The total network cable length cannot be greater than 4,000 feet. 2. Controllers can be connected in a single, continuous daisy chain. However, Keri Systems PXL-250 controllers can be connected in certain extended network configurations (subject to certain limitations). The following rules apply for extended network configurations. 1. The controller network can be wired in a “Star” pattern. 2. The network cable length of a daisy chain connected to the master controller (at the center of the star) cannot be greater than 5,000 feet. 3. The total network cable length cannot be greater than 16,000 feet. Please refer to Appendix 3, the Network Wiring Application Note (p/n 01824-001), for detailed information on extended network configurations. NOTE: Keri Systems defines a “Star” pattern as multiple sets of daisy chained controllers all connected to the master controller at the center of the star. 01836-002 Rev. 3.1 Page 16 of 46 Printing Date October-1998 Technical Reference Manual – PXL-250 NOTE: Communication buses such as RS-485 often appear to work even if installed incorrectly, but can have intermittent problems making problem diagnosis difficult. Failure to properly install an RS485 network can result in network communication errors and can cause the access control system to lock up. Although Keri Systems has lab tested the functionality and data integrity of the extended network configurations, no guarantees can be given for extended network configurations. Jumper Settings On the PXL-250 controller, there is only one jumper that may require setting. JP4 sets the power supply voltage with which the controller powers the reader (see Figure 3). 5 5 6 6 7 7 TB5 TB6 6 1 3 12VJP4 5V Figure 3 – Setting the JP4 Jumper Installing the Enclosure The PXL-250 controller enclosure may be installed on any kind of wall material: wood, sheet-rock, concrete, or metal. Mount the 12 VDC power supply for the PXL-250 controller three feet or greater from the controller to provide a degree of isolation from EMI that may be generated by the power supply. Always be aware of sources of EMI that may affect the operation of the PXL-250 controller and make your installations away from these sources whenever possible. The enclosure's mounting holes are found at each corner of the unit (top left, top right, bottom left, and bottom right). To mark a surface for drilling enclosure mounting holes, simply place and hold the enclosure in the desired location and with a pencil or scribe place a mark on the mounting surface at each mounting hole. Note the location of the enclosure's knockouts (circular, removable plates on the enclosure's base plate) and remove the knockout that allows you to route your cables into the enclosure in the easiest, most direct path. Understanding Inputs and Outputs The following section provides descriptions of all Inputs and Outputs on the PXL-250 controller. Wiring diagrams for all inputs and outputs are included in the next section, Wiring Connections, which begins on page 21. Printing Date October-1998 01836-002 Rev. 3.1 Page 17 of 46 SYSTEM INSTALLATION JP4 - Reader Power Supply Voltage – Jumper across JP4 pins 1 and 2 enables 12 VDC power for readers. All Keri Systems proximity readers require 12 VDC. This is the factory default setting for PXL-250 controllers shipped with proximity readers. – Jumper across JP4 pins 2 and 3 enables 5 VDC power for readers. Most Wiegand output devices require 5 VDC. This is the factory default setting for PXL-250 controllers shipped with a Wiegand compatible reader interface. If your Wiegand compatible reader requires 12 volts, move the jumper from pins 2 and 3 to pins 1 and 2. Technical Reference Manual – PXL-250 Controller Inputs An input detects a state change generated by a device outside of the controller. The controller then responds to that state change. The input devices that generate the state change may be normally closed or normally open. SYSTEM INSTALLATION A normally closed input device continually keeps a circuit closed or complete. A state change is generated when the normally closed input device is opened, breaking the circuit. In an access control system, a door switch is a typical example of a normally closed device. While the door remains closed, the switch remains closed. When someone opens the door, the door switch is opened, breaking the circuit and generating a state change. The controller then responds to this state change and generates an output (such as sounding an alarm if the door is a secure door). A normally open input device continually leaves a circuit open or incomplete. A state change is generated when the normally open input device is closed, completing the circuit. In an access control system, a request-to-exit (RTE) button is a typical example of a normally open device. In an access control installation, an RTE button is located on the secured side of the door. While there is no one at the door pressing the button, the switch remains open. When someone desires to exit through a secure door, they press the RTE button, closing the circuit and generating a state change. The controller then responds to this state change and generates an output (such as unlocking the door to allow egress). Door Status Switch Input The door status switch input accepts a signal from a normally closed input switch that indicates the status of the door: open or closed. While the door remains closed, the switch remains closed. When someone opens the door, the door switch is opened, breaking the circuit and generating a state change. The controller responds to this state change and generates an alarm output if the door is forced or held open too long. Refer to Figure 12 on page 27 for a typical door status switch wiring diagram. NOTE: A door switch must be installed on any door to which anti-passback is being applied for proper tracking of the anti-passback feature in the Doors32 program. NOTE: If the door status switch is not being used, a jumper must be installed across pins 1 and 2 of TB-4 to prevent a continuous door open alarm from being received by the controller and to ensure proper operation/annunciation of Door Forced and Door Held Open alarms. Request to Exit Input The request to exit (RTE) input accepts signals from a normally open input device that indicates that a request has been made for someone to exit a secured door. Motion detectors, pressure-sensitive floor mats, or push buttons may make RTE requests. While there is no one there to activate the RTE request, the input remains open. When someone desires to exit through a secure door, they activate the RTE device, closing the circuit and generating a state change. The controller then responds to this state change and generates an output unlocking the door to allow egress. Refer to Figure 11 on page 27 for a typical RTE wiring diagram. General Purpose Input The general-purpose input accepts signals from a normally closed input device that indicates when a change in state has occurred. While the input device is in its normal state, the general-purpose input circuit remains closed. When the input device is activated, the general-purpose input circuit is opened generating a state change. The controller may respond to this state change per programmed instructions. The general-purpose input is configured through the Doors32™ access control software. 01836-002 Rev. 3.1 Page 18 of 46 Printing Date October-1998 Technical Reference Manual – PXL-250 There are three possible uses for the general purpose input. • • • Global Unlock input (ONLY on the master controller – configured in the Doors32™ program). Auxiliary RTE input for the A-door (configured in the Doors32™ program). General Purpose input Using the general purpose input for global unlock allows an operator to unlock all doors, immediately (this input is only valid on the master controller). Using a normally closed switch as the input device, while the switch is in its normal state, the general-purpose input circuit remains closed. When the operator opens the switch, the general-purpose input circuit is opened generating a state change. The master controller then responds to this state change per programmed instructions and generates a command to all controllers to unlock all doors and allow immediate egress. Refer to Figure 8 on page 25 for a typical global unlock input wiring diagram. When not used for global unlock or auxiliary RTE, the general-purpose input can accept signals from either a normally closed or a normally open input device that indicates when a change in state has occurred. For a normally closed input device, while the input device is in its normal state the generalpurpose input circuit remains closed. When the input device is activated, the general-purpose input circuit is opened generating a state change. The controller can respond to this state change per programmed instructions. For a normally open input device, while the input device is in its normal state the general-purpose input circuit remains open. When the input device is activated, the generalpurpose input circuit is closed generating a state change. The controller can respond to this state change per programmed instructions. The general-purpose input is configured through the Doors32™ program. Refer to Figure 10 on page 26 for typical general-purpose input wiring diagrams. Controller Output Relays In many respects, a Form C output relay performs the opposite task of an input. An input detects a state change generated by a device outside of the controller. An output relay receives a signal from the controller that energizes the output relay, switching its state. This state change typically prompts an action outside of the controller. The inputs drive the signals that control the output relays. An example of this process is when a secure door is forced open. As the door is opened, the door status switch opens. The door status switch input detects the switch's state change. The controller sends a signal instructing the alarm relay to energize. The alarm relay switches its state to activate an audio alarm notifying everyone in the immediate area that the door has been forced open. A variety of devices may be activated by an output relay such as an electric door strike, a magnetic lock, an alarm, a light, a video camera, or a modem. A Form C relay has both normally closed and normally open circuits. When the relay is not energized, the normally closed circuit is complete and the normally open circuit is open. When the relay is energized the circuits switch roles; the normally open circuit is closed and the normally closed circuit is open. This dual nature of Form C relays (having both normally closed and normally open circuits) allows for two types of applications outside the controller. A device may be attached to the normally closed circuit so that it is always on until the relay energizes to open the circuit and turn it off. Or, a device may be attached to the normally open circuit so that it is always off until the relay energizes to turn it on. Printing Date October-1998 01836-002 Rev. 3.1 Page 19 of 46 SYSTEM INSTALLATION Using the general purpose input for auxiliary RTE allows a second RTE switch to be used to unlock the A-door at a controller. Using a normally open switch as the input device, while the switch is in its normal state, the general-purpose input circuit remains open. When a person requesting egress closes the switch, the general-purpose input circuit is closed generating a state change. The controller then responds to this state change per programmed instructions and generates a command to unlock the door and allow egress. Refer to Figure 9 on page 25 for a typical auxiliary RTE input wiring diagram. Technical Reference Manual – PXL-250 Lock Relay Unlocking a door is controlled by the Form C lock relay. When installing a door lock there are two things to consider: safety versus security, or should the door be "fail-safe" or "fail-secure." Fail-safe means that if the power should fail at a door (perhaps due to a power outage or equipment failure), the door will automatically unlock allowing entrance and egress. Power is required to keep the door locked. A fail-safe door ensures people will be able to enter and exit a secured area through that door in the case of an emergency. SYSTEM INSTALLATION A typical fail-safe application may use a magnetic lock. In this application, the controller energizes the lock relay, causing the lock relay to change its state. In its new state the normally closed circuit is opened breaking the power to the magnetic lock and allowing the door to be opened. Refer to Figure 14 on page 29 for a typical fail safe lock relay wiring diagram. Fail-secure means that if the power should fail at a door (perhaps due to a power outage or equipment failure), the door will automatically lock and not allow entrance but will continue to allow egress. Power is required to unlock the door. A fail-secure door ensures a secured area remains secure regardless of the situation. A typical fail-secure application may use a door strike. In this application, the controller energizes the lock relay, causing the lock relay to change its state. In its new state the normally open circuit is closed activating the release mechanism for the door strike on the door to be opened. Refer to Figure 15 on page 29 for a typical fail secure lock relay wiring diagram. Alarm Out Relay Activating an audio (or a silent) alarm is controlled by the alarm out relay. The controller energizes the alarm out relay, causing the alarm out relay to change its state. In its new state the normally open circuit is closed activating the alarm. Refer to Figure 13 on page 28 for a typical alarm out relay wiring diagram. 01836-002 Rev. 3.1 Page 20 of 46 Printing Date October-1998 Technical Reference Manual – PXL-250 Wiring Connections Before performing any wiring or connection operations, ensure that controller power is OFF. Serious damage to sensitive components on the controller may occur if wiring changes are made while controller power is on.

To remove the terminal block from the printed circuit board, grasp the terminal block and gently pull it away from the printed circuit board. Figure 5 – Installing Wiring and Removing a Terminal Block For a first-time installation, Keri recommends you make all wiring connections in the following order, installing the wiring from the terminal block connections at the bottom of the controller to the top. This will allow you to route and install the cables in a sequential order and it ensures that an adequate earth ground is attached to the controller before power is applied. WIRING CONNECTIONS TB-5/TB-6 – Reader Connection The inputs on TB-5 accept wiring from Keri Systems proximity readers or from Wiegand compatible devices. To use Wiegand compatible devices a Wiegand receiver board must have been installed on the PXL-250 controller by the factory. A Wiegand compatible controller (a PXL-250W) will have "WIEGAND INTERFACE" stenciled on the receiver PCB. A Keri Systems proximity controller (a PXL250P) simply states "RECEIVER BOARD." Refer to Figure 4 on page 21 for the location of the receiver board. Two readers may be installed for one door to allow for access control in both directions. The "A" reader, allowing entrance, is connected to TB-5 on the PXL-250 motherboard. The "B" reader, allowing egress, is connected to TB-6 on the receiver board. If your application uses just one reader, connect it to TB-5 on the PXL-250 motherboard.

Up to 128 controllers can be attached to this network. Per the RS-485 specification this network must be in a daisy chain with a total network cable length of no greater than 4,000 feet. To provide the best operating conditions for the RS-485 communication network, the PXL-250 controller automatically configures three network setup requirements using circuitry embedded on each controller. 1. The last controller on the network is automatically configured for end-of-line termination. 2. The necessary network biasing resistors are automatically implemented. 3.

These configurations include a “star” pattern network communication bus, a spur cable length of up to 5,000 feet, and a total network cable length of up to 16,000 feet. Refer to Addendum 3, PXL-250 Network Wiring Application Note (p/n 01824-001), for detailed information on extended network configurations. RS-232 Controller/PC Connection In either case, a connecting cable is available from Keri Systems (PXL to PC or PXL to modem), or you may make your own cable. If you make your own cable, please install housings on each connector to protect the wire/connector pin junctions. NOTE: When using 56K modems to communicate with remote access control networks, all modems must use the same communication format – either X2 or Flex. Incompatibilities between the two formats make some modems of one format incapable of reliable communication with modems of the competing format. Modems using the V.90 specification are compatible regardless of whether they are from an X2 or Flex manufacturer. NOTE: Do not use male/female gender change plugs or 25-pin to 9-pin adapters when making RS232 serial port connections, these devices may have internal wiring changes that can disrupt communications when implemented in conjunction with the Keri Systems serial wiring instructions. If you must use a gender changer plug, ensure it is a "straight-through" plug. Printing Date October-1998 01836-002 Rev. 3.1 Page 31 of 46 WIRING CONNECTIONS The RS-232 serial port (see Figure 4 on page 21) provides a communication link between the access control network of PXL-250 controllers and the host computer running the Doors32™ access control software. This link can be made via a serial cable directly connecting the serial port of the master PXL-250 controller and the host computer, or it can be made via a modem making a remote connection between the master PXL-250 controller and the host computer. The PXL-250 controller will automatically determine the communication method (direct or modem) and will configure itself accordingly. Technical Reference Manual – PXL-250 Direct PC to Controller Serial Connection If the host computer has a male DB-9 connector on the serial port, you must use a Keri Systems KDP-252 cable or create a cable according to Table 16 and Figure 18.

When powering on the system for the first time, the installer should verify the 12 VDC controller supply voltage and reset system RAM to ensure proper operation of the PXL-250 controller. Verify 12 VDC Supply Voltage To verify the 12 VDC supply voltage: 1. 2. 3. 4. set the DVM to a DC volts scale capable of reading 12 VDC place the Red DVM lead on Pin 1 of TB-2 place the Black DVM lead on Pin 2 of TB-2 check the DVM reading – it should read between +12 VDC to +14 VDC If the DVM does not read 12 VDC, verify the power supply is of the correct voltage, verify the cable length does not exceed 200 feet, and verify the cable gauge is AWG 18. NOTE: On long power cable runs, keep in mind the resistance in the cable itself causes a drop in voltage at the end of the run. The power supply must be able to account for this voltage drop. Verify Wiegand Compatible Reader Supply Voltage All Keri Systems proximity readers use 12 VDC power while most Wiegand compatible readers use 5 VDC power. For Wiegand configured PXL-250 controllers, there is a warning LED on the receiver board to indicate if the controller is applying 12 VDC to the Wiegand compatible reader (see Figure 23). If your Wiegand compatible reader does operate on 5 VDC no changes need to be made, the default position for the jumper is to set power to 5 VDC. If your Wiegand compatible reader requires 12 VDC, turn the controller power off and follow the instructions in the Jumper Settings section on pages 17 and 18 to set the reader supply voltage to 12 VDC. When power is restored, the warning LED will turn on indicating 12 VDC is being supplied to the Wiegand compatible reader. WARNING! IF LIT, 12 VOLTS IS ON CARD READER, TO SELECT 5 VOLTS, CHANGE JP4 ON MOTHER BOARD DESIGN6 PXL-250 WIEGAND INTERFACE Resetting the Controller's RAM If you’re turning system power on for the first time, the PXL-250 controller's RAM must be reset before performing any other action. This clears any spurious information that may be in the RAM in preparation for entering your access control information. On the controller, insert a jumper across pins 1 and 2 of JP3. Hold the S1 Address and Diagnostics Button down (see Figure 4 on page 21 and Figure 24 on page 37) and turn the controller's power on. Printing Date October-1998 01836-002 Rev. 3.1 Page 37 of 46 OPERATION & MAINTENANCE Figure 23 – Wiegand 12 VDC Warning LED Technical Reference Manual – PXL-250 The beeper for the reader attached to the controller will beep as power comes on followed by a beepbeep indicating the controller's firmware has reset the controller's RAM. Release S1. If the optional Alpha/Numeric Plug-in Display has been installed, it will display a "SYSTEM RESET" message. Remove the jumper on JP-3. The controller is now ready for use. RESET JP-3 Address Display S1 - Address & Diagnostics Button Figure 24 – Close-Up of JP-3, S1, and Address Display LEDs NOTE: Resetting the system RAM completely erases all information within the PXL-250 controller. Should there be any information in system RAM from an access control installation and the system RAM is reset, the information in the controller is lost and cannot be recovered from the controller. Normal Operation For normal operation, turn the system power on. The power LED should be on. On the master controller the network LED should be blinking, indicating it is communicating with other PXL-250 controllers on the network. If this is a single controller network, the LED will blink for several minutes until it determines that there are no other controllers with which to communicate, then it will turn off. The address programmed into the controller will flash on the address display LEDs for 2 seconds. If the optional Alpha/Numeric Plug-in Display has been installed, it will display a Keri Systems header and the controller's address (see Figure 25). * KERI SYSTEMS * UNIT XX OPERATION & MAINTENANCE Figure 25 – PXL-250 Controller Standard Operation Message Viewing Controller Addresses To view a controller's address, click S1 (see Figure 4 on page 21 and Figure 24). The controller's address will appear on the address display for 2 to 3 seconds. Setting Controller Addresses To set the desired operating address for the controller, turn the controller's power off. Verify JP3 is not installed (if JP3 is installed, the controller RAM will be reset when the power is turned on). Hold the S1 Address and Diagnostics Button down and turn the controller's power on. The beeper for the reader attached to the controller will beep as power comes on followed by a beep-beep indicating the controller's firmware has entered the address setting mode. Release S1. The address display LEDs then become active and the controller's address can be set. If an Alpha/Numeric Display (LCD-1) is 01836-002 Rev. 3.1 Page 38 of 46 Printing Date October-1998 Technical Reference Manual – PXL-250 connected to the controller, "Address Change" will appear on the display. The address range is from 1 to 128 (the Master Controller must always be set to address 1). Quickly double clicking S1 toggles between increasing and decreasing the controller address. The top LED character will display either a “+” or a “-” to show which direction is active. A single click of S1 changes the controller address by 1. If you’re at address 128, a +1 click will roll the address over to 1; conversely, if you’re at address 1 a -1 click will roll the address over to 128. Holding S1 down rapidly scrolls through the addresses. Click through the address range until the desired address is displayed by the address display LEDs. After the new address has been set, you must wait approximately 30 seconds. There is a timer in the controller's firmware that assumes that after 30 seconds of inactivity (no address clicks), the entered address is the desired address for that controller. When the 30-second timer expires, there will be a beep-beep indicating the controller has recognized and accepted the new address and the address LEDs will turn off. If an Alpha/Numeric Display (LCD-1) is connected to the controller, "UNIT ##" will appear on the display (where ## is the controller's address – see Figure 25 on page 37). Master Controller Requirements The master controller must be set to address 1 so that all slave controllers on the access control network can identify the master controller. For the master controller to correctly identify all slave controllers on the network, one of two things must be done. 1) The master controller must be the last unit on the network to be powered on. This ensures that when the master controller begins polling the network to see what slave units are connected for system configuration, all slave units are already communicating their unique addresses and their configuration information. 2) The Auto-Configuration routine within the Doors32™ program must be run. This instructs the master controller to poll all controllers on the network for addresses and configuration information (the Auto-Configuration button is found under the Setup/System/controllers tab). Proximity Reader Responses to Access Control Events During day-to-day activity, a proximity reader will respond to access control events in a specific manner.

Verify the controller's earth ground is still a quality earth ground. 2. Verify all terminal block connections continue to be secure. 3. Perform the signal strength test found in the Troubleshooting and Diagnostics Appendix to ensure that reader signal quality at the controller is maintained and that reader read range continues to be high. 4. If the controller has a backup battery for operation during a power outage, disconnect the power and verify the controller continues to operate under backup battery power. OPERATION & MAINTENANCE If there are any concerns regarding the operation or performance of the PXL-250 controller, please review the Troubleshooting and Diagnostics Appendix. 01836-002 Rev. 3.1 Page 40 of 46 Printing Date October-1998 Technical Reference Manual – PXL-250 Glossary AUXILIARY RTE – a second input source that informs the controller that someone has requested egress from a secure area. RTE and REX are common abbreviations. See REQUEST TO EXIT. COM PORT – A COM port is a hardware device that allows a computer to communicate with external devices. CONTROLLER – a central unit containing a microprocessor, a database, inputs, and outputs. The microprocessor processes information received from the inputs, compares it to information in the database, and determines if an output should be generated. DOOR FORCED ALARM – a door that is forced open generates a door forced alarm. DOOR HELD OPEN ALARM – a door that is held open beyond the Open Time (as programmed in the Doors32™ program) generates a held open alarm. DOOR SWITCH – a switch that reflects the current state of the door: if the door is open, the switch is open; if the door is closed, the switch is closed. EARTH GROUND – an electrical connection point that brings all electrically neutral lines to the earth's surface potential (essentially zero potential). A good earth ground protects electrical devices from transients such as power surges and lightning strikes, and drains electrical interference from data, communication, and power lines that support these electrical devices. ELECTROMAGNETIC INTERFERENCE – Excess electromagnetic energy radiated by an electrical device that may affect the operation of other electrical devices. EMI – see ELECTROMAGNETIC INTERFERENCE. FAIL-SAFE – fail-safe means that if the power should fail at a door, the door will automatically unlock allowing egress. A fail-safe door ensures people will be able to exit a secured area through that door in the case of an emergency. FAIL-SECURE – fail-secure means that if the power should fail at a door, the door will automatically lock and not allow entrance, but will continue to allow egress. A fail-secure door ensures a secured area remains secure regardless of the situation. GLOBAL UNLOCK – a normally-closed input (as programmed in the Doors32™ program) that, when opened, generates a signal that unlocks all doors in the access control network. INPUT – an electronic sensor on the controller that detects a change of state in a device outside the controller. See NORMALLY CLOSED, NORMALLY OPEN. LOCK RELAY OUTPUT – a relay on the controller that changes its state upon command by the controller. Typically the lock relay output unlocks a secure door. NETWORK – a series of controllers linked together via a communication cable. NORMALLY CLOSED – an input device that continually keeps a circuit active or complete. A state change is generated when a normally closed device is opened. See INPUT. Printing Date October-1998 01836-002 Rev. 3.1 Page 41 of 46 GLOSSARY ALARM RELAY OUTPUT – a relay on the controller that changes its state upon command by the controller. Typically the alarm relay output activates an audible alarm. Technical Reference Manual – PXL-250 GLOSSARY NORMALLY OPEN – an input device that continually keeps a circuit open or incomplete. A state change is generated when a normally open device is closed. See INPUT. OUTPUT RELAY – a device that changes its state upon receiving a signal from the controller. Typically the state change prompts an action outside of the controller such as activating or inactivating a device. PROXIMITY – a method of reading identification codes from cards or key tags that require bringing the card or key tag within the proximity of a reader. No mechanical interaction between card and reader is required for the reader to receive the identification code. READER – a device that "reads" an identification code from a card, key tag, magnetic stripe, or related item. RELAY, FORM C – a device that has both normally closed and normally open circuits. When the relay is not energized, the normally closed circuit is complete and the normally open circuit is open. When the relay is energized the circuits switch roles, the normally closed circuit is open and the normally open circuit is complete. This dual nature of Form C relays allows for two types of applications outside the controller. A device may be attached to the normally closed circuit so that it is always on until the relay energizes to open the circuit and turn it off. Or, a device may be attached to the normally open circuit so that it is always off until the relay energizes to turn it on. REQUEST TO EXIT – a signal that informs the controller that someone has requested egress from a secure area. RTE and REX are common abbreviations. REX – see REQUEST TO EXIT. RS-232 – a serial communication protocol for connecting data terminal devices. RS-232 is the most commonly used communication protocol. It works best over shorter distances. RS-485 – a serial communication protocol for multi-drop communications. It is used for higher speed and longer distance communications. RTE – see REQUEST TO EXIT. SUPPRESSION – the addition of a device to an electrical circuit that minimizes or prevents transients from affecting the proper operation of that circuit. TRANSIENTS – electrical surges or spikes conducted through power or data lines. Transients are generated as electrical devices are turned on or off. TRANSORB – an electrical suppression device. See SUPPRESSION. WIEGAND COMPATIBLE DEVICES – a proprietary coding format for information used by many of the suppliers of cards, key tags, proximity readers, magnetic stripe readers, bar code readers, and related items. 01836-002 Rev. 3.1 Page 42 of 46 Printing Date October-1998 Technical Reference Manual – PXL-250 Index Printing Date October-1998 Request to Exit, 18 Connections, 26 REX.

The PXL-250 uses a half-duplex, RS-485 communication bus. Per the RS-485 specification, the access network communication bus is guaranteed to communicate with a total network cable length of up to 4,000 feet and with the controllers connected in a single, continuous daisy chain. However, Keri Systems has identified specific extended network configurations that could be used to wire a controller network communication bus (subject to certain limitations defined on page 2). These configurations include a “star” pattern network communication bus, a spur cable length of up to 5,000 feet, and a total network cable length of up to 16,000 feet. Lab tested extended network configurations are presented beginning on page 2. Cable Requirements The RS-485 network should be wired using a cable with the following characteristics: twisted, shielded pair of stranded AWG 24 conductors (such as Belden 9501 or a larger gauge). Earth Ground Requirements A quality earth ground connection to the master controller is required to ensure the best possible operating conditions. Without a quality earth ground connection, an access control network may appear to operate correctly, but will be extremely susceptible to transients and electromagnetic interference. An earth ground brings all electrically neutral lines to the earth’s surface potential (essentially a zero potential) providing three benefits. Application Note Network Requirements 1. An earth ground protects the network from electrical transients such as power surges and lightning strikes (also providing a degree of safety for an operator). 2. An earth ground provides a path to ground for electrical interference, minimizing data and communication problems for the reader data and network communication lines. 3. Through a feature on the PXL-250 controller, the shield for the entire RS-485 network is automatically grounded at the master controller minimizing communication problems. Possible earth ground sources: copper shrouded ground rod cold water pipe (must be a metal pipe – not PVC) steel building frame member (if the building’s frame is embedded in the earth) electrical system ground (at the breaker/fuse box) telephone system ground NOTE: Communication buses such as RS-485 often appear to work when installed incorrectly, but can have intermittent communication problems. This intermittence can make diagnosing a problem difficult. Failure to properly install an RS-485 network can result in network communication errors and can cause the access control system to lock up.

The extended network configurations described in this section have been verified in the lab to provide proper, reliable communication between all controllers in an access control network. Extended Network Guidelines There are several guidelines for installing an extended network. 1. The network uses a “star” pattern communication bus. Keri Systems defines a star pattern as a communication network with sets of daisy chained controllers all connected to the master controller at the center of the star. 2. Any daisy chain off the star can have a maximum cable length of 5,000 feet. 3. The total cable length of all daisy chains can be no more than 16,000 feet. 4. Any number of daisy chains can be installed as long as the cabling for these daisy chains meets the above guidelines. 5. Any number of controllers can be installed in any daisy chain (up to the 128-controller limit for the entire network). The Master Controller For the best operating conditions the master controller for the access control network should be at center of the star. If an existing network is being upgraded to an extended network or when installing a new extended network, the master controller printed circuit board must be at level –002 Rev. A or greater to ensure proper network termination. The printed circuit board level information is at the lower right corner of the board (see Figure 1). PXL-250 Lithium Battery 04174- 002 REV A Figure 1 – Location of Printed Circuit Board Level NOTE: Keri Systems has tested the functionality and data integrity of the extended network configurations presented in this document under lab conditions. Because of the nature of extended networks, the operation of extended networks in the field is strongly dependent upon the quality of the installation. 1530 Old Oakland Road, Suite 100 01824-002 Rev.

Certain star networks may have more spurs to be wired than can be held by the wiring locations. External jumper blocks can be used to make these connections. Perform the following steps to make an external jumper block. Application Note Figure 2 is a generic drawing for an extended network, meeting the guidelines listed above. 1. Count how many spurs have been run to the master controller. 2. Provide jumper blocks with enough connector points to support three times the number of spurs (each spur has three wires: Tx-, Tx+, and Shield). This can be individual jumper blocks with three connectors for each spur or one large jumper block with enough connectors to handle all 3 sets of wires from all spurs (see Figure 3). 4 spurs x 3 wires per spur = 12 wire connection points TxTx+ Shield Spur #2 TxTx+ Shield Spur #3 TxTx+ Shield Spur #4 TxTx+ Shield OR PXL-250 Spur #1 Figure 3 – Determining the Number of Jumper Block Connector Points NOTE: The remaining figures assume one large jumper block with enough connectors to handle all 3 sets of wires from all spurs has been provided for connecting wires. 3.

Clicking S1 once advances to the next test. Double-clicking S1 enters the test identified on the display. Receiver A and B Signal Quality Tests The receiver input signal quality tests provide a measure of the strength of the signal and the amount of interference in the signal received by a PXL-250 controller from the A-Reader or BReader. There are two methods for measuring receiver input signal quality: the on-board diagnostics and measuring with a DVM (instructions for measuring with a DVM are provided in a separate section, later in this document, for installations without an LCD-1 display). NOTE: The Receiver Signal Quality Tests are only valid for Keri Systems proximity readers. These tests are not valid for Wiegand readers or for proximity readers from other manufacturers. The steps for performing the Receiver A and Receiver B Signal Quality Tests are identical. The following instructions may be applied to either test. 1.

Monitor the MV reading over a period of time. The reading fluctuates as the signal strength fluctuates. Determine an average value for this reading. The average value should be around 500 mV. This indicates the PXL-250 controller is receiving a reader signal with little electrical interference. A higher reading indicates the controller is receiving electrical interference that may affect the reader's signal. The higher the reading, the more interference is being received which directly affects the reader's read range. A lower reading indicates the controller is receiving a weak signal from the reader. The lower the reading, the weaker the signal being received, which directly affects the reader’s read range.

This can help verify the integrity of the controller communication network. A polling cycle is defined as the set of network communications between the master controller as it contacts each slave controller in the access control network, one-at-a-time, monitoring slave controller status. 1. Once in the diagnostic routines, single-click S1 until the Net Error Rate Test header appears on the LCD display (see Figure 6). * KERI SYSTEMS * NET ERROR RATE Figure 6 – Net Error Rate Screen 2. Double-click to enter the diagnostic routine. Three sets of numbers appear on the LCD display (see Figure 7). Each set of numbers corresponds to different kind of network error count. ## * KERI SYSTEMS * ## ## Troubleshooting and Diagnostics PXL-250 Figure 7 – Net Error Rate Fields 3. The first set is a count of the number of network errors that have occurred on the current polling cycle. If network errors are occurring during the current polling cycle, this counter will increase until the end of the polling cycle. When a new polling cycle begins this number resets to zero. 4. The second set is a count of the highest number of network errors that have occurred on any single polling cycle since the test began. 5. The third set is a count of the total number of network errors that have occurred over all polling cycles since the test began. NOTE: A number of network errors will be reported during an auto-configuration initiated by the Doors/Doors32 program. This is due to the master controller polling all 128 possible controllers on the network to determine which controllers are actually connected. Errors during an autoconfiguration cannot be considered valid errors. Exiting Diagnostics 1. Single-click S1 until the Exit header appears on the LCD display (see Figure 8). * KERI SYSTEMS * EXIT Figure 8 – Exit Diagnostics Screen 2.

Remove TB-6 from the receiver board. 2. Disconnect the wire at TB-6, pin 1. 3. Loosen the wire connection at TB-5, pin 1 and attach a jumper wire between TB-6, pin 1 and TB-5, pin 1. 4. Tighten both connections and reinstall TB-6 on the receiver board. 5. Set the DVM to a range that allows it to read between 500 mV to 2 volts DC. 6. Connect the ground lead of the DVM to TP-2 on the receiver board. 7. Connect the positive lead of the DVM to TP-1 on the receiver board. 8. Take the reading from the DVM. Reader "B" Measurement (refer to Figure 9) 1. Remove TB-6 from the receiver board. 2. Disconnect the wire at TB-5, pin 1. 3. Loosen the wire connection at TB-6, pin 1 and attach a jumper wire between TB-6, pin 1 and TB-5, pin 1. 4. Tighten both connections and reinstall TB-6 on the receiver board. 5. Set the DVM to a range that allows it to read between 500 mV to 2 volts DC. 6. Connect the ground lead of the DVM to TP-2 on the receiver board. 7. Connect the positive lead of the DVM to TP-1 on the receiver board. 8. Take the reading from the DVM. Reference Document Receiver Signal Quality Test – DVM The receiver input signal quality tests provide a measure of the strength of the signal and the amount of interference in the signal received by a PXL-250 controller from the A-Reader or BReader. There are two methods for measuring receiver input signal quality: the on-board diagnostics and measuring with a DVM (the on-board diagnostics method is described earlier in this document). Be sure to remove the jumper wire between TP-6, pin1 and TP-5, pin1. Be sure to restore the "A" reader lead to TB-5, pin 1 and the "B" reader lead to TB-6, pin 1. A higher reading indicates the controller is receiving electrical interference that may affect the reader's signal. The higher the reading, the more interference is being received which directly affects the reader's read range. A lower reading indicates the controller is receiving a weak signal from the reader. The lower the reading, the weaker the signal being received, which directly affects the reader’s read range. Troubleshooting and Diagnostics PXL-250 The average value should be around 500 mV. This indicates the PXL-250 controller is receiving a reader signal with little electrical interference. 1530 Old Oakland Road, Suite 100 01841-001 Rev.

However, the wire gauge to use should be determined by the current draw requirements of the Wiegand device and the actual length of the cable run. A +5 VDC Wiegand device must have +5 VDC at the device (long cable runs have a voltage drop across the length of the run due to the resistance in the cable). To ensure +5 VDC is available at the device a larger gauge of wire (having less resistance) or a separate power supply at the Wiegand device may be required. Input and Output Connections • two conductor, stranded, AWG 22 (or a larger gauge) NOTE: The Lock Output relay may require a heavier gauge of wire depending upon the current demands of the lock and the length of the lock wiring run.

Set the DVM to a DC volt scale capable of reading 12 VDC. Place the Red DVM lead on Pin 1 of TB-2. Place the Black DVM lead on Pin 2 of TB-2. Check the DVM reading. It should read +12 VDC +/- 2 volts. If the DVM does not read 12 VDC, verify the power supply is of the correct voltage, verify the cable length does not exceed 200 feet, and verify the cable gauge is AWG 18. NOTE: On long power cable runs, keep in mind the resistance in the cable itself causes a drop in voltage at the end of the run. The power supply must be able to account for this voltage drop. Verify the Wiegand Reader Supply Voltage All Keri Systems proximity readers use 12 VDC power while most Wiegand compatible readers use 5 VDC. For Wiegand configured PXL-250 controllers, there is a warning LED on the receiver board to indicate if the controller is applying 12 VDC to the Wiegand compatible reader. If your Wiegand compatible reader does operate on 5 VDC no changes need to be made; the default position for the jumper is to set power to 5 VDC. If your Wiegand compatible reader requires 12 VDC, turn the controller power off and move the jumper on JP4 (at the lower left-hand corner of the controller) from pins 2-3 to pins 1-2. When power is restored, the warning LED will turn on indicating 12 VDC is being supplied to the Wiegand compatible reader. NOTE: Resetting the system RAM completely erases all information within the PXL-250 controller. If there is any information in system RAM from an access control installation and the system RAM is reset, the information in the controller is lost and cannot be recovered. Viewing the Controller's Address To view the controller’s address, click S1. The controller’s address will appear on the address display for 2 to 3 seconds. PXL-250 Resetting the Controller's RAM If you’re turning system power on for the first time, the PXL-250 controller’s RAM must be reset before performing any other action. This clears any spurious information that may be in the RAM in preparation for entering your access control information. On the controller, insert a jumper across pins 1 and 2 of JP3. Hold the S1 Address and Diagnostics Button down and turn the controller’s power on. The beeper for the reader attached to the controller will beep as power comes on followed by a beep-beep indicating the controller's firmware has reset the controller's RAM. Release S1. If the optional Alpha/Numeric Display has been installed, it will display a "SYSTEM RESET" message. Turn system power off and remove the jumper on JP3. The controller is now ready for use. Quick Start Guide NOTE: Before turning the power on for the first time, please verify the earth ground has been connected at pin 3 of TB-2. Setting the Controller's Address To set the desired operating address for the controller, turn the controller’s power off. Verify JP3 is not installed (if JP3 is installed, the controller RAM will be reset when the power is turned on). Hold the S1 Address and Diagnostics Button down and turn the controller’s power on. The beeper for the reader attached to the controller will beep as power comes on followed by a beep-beep 1530 Old Oakland Road, Suite 100 01835-002 Rev. 3.2 San Jose, CA 95112 USA (800) 260-5265 (408) 451-2520 FAX (408) 441-0309 Page 13 of 16 Quick Start Guide PXL-250 Tiger Controller indicating the controller's firmware has entered the address setting mode. Release S1. The address display LEDs then become active and the controller's address can be set. If an Alpha/Numeric Display is connected to the controller, "ADDRESS CHANGE" will appear on the display. The address range is from 1 to 128 (the Master Controller must be set to address 1). Quickly double clicking S1 toggles between increasing and decreasing the controller address. The top LED character will display either a “+” or a “-” to show which direction is active. A single click of S1 changes the controller address by 1. If you’re at address 128, a +1 click will roll the address over to 1; conversely, if you’re at address 1 a -1 click will roll the address over to 128. Holding S1 down rapidly scrolls through the addresses. After the new address has been set, you must wait approximately 30 seconds. There is a timer in the controller's firmware that assumes that after 30 seconds of inactivity (no address clicks), the entered address is the desired address for that controller. When the 30-second timer expires, there will be a beep-beep indicating the controller has recognized and accepted the new address and the address LEDs will turn off. If an Alpha/Numeric Display is connected to the controller, "UNIT ##" will appear on the display (where ## is the controller's address). The Master Controller The Master Controller must be set to address 1 so that all slave controllers on the access control network can identify the master controller. For the Master Controller to correctly identify all slave controllers on the network, one of two things must be done. 1) The master controller must be the last unit on the network to be powered on. This ensures that when the Master Controller begins polling the network to see what slave units are connected for system configuration, all slave units are already communicating their unique addresses and their configuration information. 2) The Auto-Configuration routine within the Doors™ program must be run. This instructs the Master Controller to poll all controllers on the network for addresses and configuration information (the Auto-Configuration button is found under the Setup/System/Controllers tab).

A state change is generated when the normally closed input device is forced open, breaking the circuit. In an access control system, a door switch is a typical example of a normally closed device. While the door remains closed, the switch remains closed. When someone opens the door, the door switch is opened, breaking the circuit and generating a state change. The controller then responds to the state change and generates an output (such as sounding an alarm if the door is a secure door). Normally-Open A normally open input device continually leaves a circuit open, or incomplete. A state change is generated when the normally open input device is forced closed, completing the circuit. In an access control system, a request-to-exit (RTE) button is a typical example of a normally open device. In an access control installation, an RTE button is located on the secure side of a door. While there is no one there pressing the button, the switch remains open. When someone desires to exit through a secure door, they press the RTE button, closing the circuit and generating a state change. The controller then responds to this state change and generates an output (such as unlocking the door to allow egress). Quick Start Guide A controller input detects a state change generated by a device outside the controller that may prompt a response from the controller. Input devices that generate a state change may be normally closed or normally open. This section provides a brief description of normally closed versus normally open inputs. General Information on Safety versus Security with Door Locks When installing a door lock there are two things to consider: safety versus security, or should the door be “fail-safe” or “fail-secure.” Fail-Secure Door Lock Fail-secure means that if the power should fail at a door (perhaps due to a power outage or equipment failure), the door will automatically lock and not allow entrance but will continue to allow egress. Power is required to unlock the door. A fail-secure door ensures a secured area remains secure regardless of the situation. A typical fail-secure application may use a door strike. In this application, the controller energizes the lock relay, causing the lock relay to change its state. In its new state the normally open circuit is closed activating the release mechanism for the door strike on the door to be opened. PXL-250 Fail-Safe Door Lock Fail-safe means that if the power should fail at a door (perhaps due to a power outage or equipment failure), the door will automatically unlock allowing entrance or egress. Power is required to keep the door locked. A fail-safe door ensures people will be able to enter and exit a secured area through that door in the case of an emergency. A typical fail-safe application may use a magnetic lock. In this application, the controller energizes the lock relay, causing the lock relay to change its state. In its new state the normally closed circuit is opened breaking the power to the magnetic lock and allowing the door to be opened. 1530 Old Oakland Road, Suite 100 01835-002 Rev. 3.2 San Jose, CA 95112 USA (800) 260-5265 (408) 451-2520 FAX (408) 441-0309 Page 15 of 16 Quick Start Guide PXL-250 Tiger Controller PXL-250 THIS PAGE IS INTENTIONALLY LEFT BLANK 1530 Old Oakland Road, Suite 100 01835-002 Rev. 3.2 San Jose, CA 95112 USA (800) 260-5265 (408) 451-2520 FAX (408) 441-0309 Page 16 of 16 Product Warranty All Keri Systems, Inc. products are warranted to the original Buyer to be free from defects in material and workmanship for the time period identified in Table 1.
