LANRTC 1. General Information
This installation manual is intended to assist you in installing, connecting and commissioning the LANRTC.
Information or drawings going beyond the content of this manual are available on request.
This device is intended exclusively for use in time recording and access control systems.
The device acts as an interface converter between Ethernet and an RS485 bus.
Any other use than that indicated is not permitted!
This device has been constructed and tested in accordance with the relevant current technological regulations. It left the factory in perfect condition in terms of technological safety and reliability. To maintain this condition and to ensure riskfree operation, the instructions and warnings given in this assembly guide must be observed by the user.
• The device may only be used for the purpose intended by the manufacturer.
Electromagnetic compatibility:
• The device is designed for use in residential, business and commercial areas and conforms to EN 61000-6-2 and 61000-6-3.
• The PCB is at risk from electrostatic discharge and the relevant precautionary measures should be observed
(earthing, etc.).
• The installation and assembly of electrical devices may only be carried out by an electrical engineer.
• Before opening the unit, always switch off the power supply and verify that the device is free of voltage by performing a measurement.
• During assembly, please ensure that the requirements laid down in the relevant device safety standard for the unit are not negatively affected, as this would reduce the safety level of the unit.
• Before switching on, ensure that the operating and control voltages connected do not exceed the permissible values in accordance with the technical data.
• This unit conforms to EN 60950-1 protection class III
• The units must be operated with safety extra low voltage
(SELV)!
• These devices may only be operated when fully assembled.
• The locking screws on unassigned connection terminals should be screwed in as far as they will go.
• If it has to be assumed that danger-free operation is no longer possible, take the unit out of operation and secure against accidental use.
• If the failure or malfunctioning of the unit may result in injury to persons or animals or in damage to works equipment, this must also be prevented using additional safety measures (limit switch, safety devices, etc.).

The device was manufactured using recyclable materials and components.
When disposing of the device and the packaging, please ensure environmentally friendly recycling.
Information for EU Countries
European Directive 2002/96 EC applies to this device.
This means that this product must not be disposed of with normal household waste. We, the manufacturer, will take back our electric and electronic products and dispose of them for you free of charge. Correct disposal of your old equipment protects people and the environment from
The LANRTC permits the connection of two-wire sub-devices to a LAN host.
For connecting the sub-devices there is an RS485 bus available.
• In the event of a fault, the LANRTC automatically repeats buffer-stored data sets or requests these from the network subscribers.
• It monitors the availability of the network subscribers and informs the terminal of the condition of the network.
The LANRTC thereby assumes the following duties:
• As pollmaster, it controls the data transfer to the subnet.
• As gateway, it transmits data sets from the LAN to the subnet.
• It controls the data distribution to the terminal networks connected to the LAN and to the master terminal.
It controls the rhythm check of the sub-terminal, depending on the availability of the other LAN terminals or LANRTCs.

2. Assembly
For assembly and installation of the LANRTC it is necessary to remove the upper side of the device housing.
First remove the special screw on the end of the device using a cross-head screwdriver.
The upper side of the housing can now be pushed back and lifted off from above.

LANRTC 2. Assembly
Space requirement: When planning the installation location for the terminal, sufficient space must be ensured for unhindered operation and service work.
If the LANRTC is to be equipped with the optional built-in power supply unit, this must be installed before the LANRTC is fastened to the wall.
Before drilling, ensure that you will not damage any cables, etc. located underneath the plaster.
First mark two mounting holes according to the drilling pattern and drill using a 6 mm drill bit.
The scope of supply includes two dowels and two Spax screws for wall installation of the LANRTC.
The cables can now be laid through the cable inlets at the correct point, cut to the correct length, the terminals fitted and the cable strain relief clips installed.

LANRTC 2. Assembly
Use the strain relief clamp when laying the wiring of the
LANRTC.
Remove the cable sheathing between strain relief clamp and connecting terminals. Then fold the screen back by approx.
10 mm onto the sheath. Now fasten the cable to the strain relief clamp using cable binders.

The device can be equipped with a power supply unit.
To make the connection, connect the phase and the neutral wire directly to the power supply unit.
In the casing, the earth conductor must be connected to the screw labelled with the earth conductor symbol.
The device is designed for a permanent connection to the power supply circuit only.
It must be connected by a qualified electrician only.
The power supply circuit for this device requires a suitable, easily accessible power isolating device with a minimum contact gap of 3 mm and a fuse element to protect against short circuits, both already provided on site.
The earth conductor must be connected.

5.1.2 General information on changing the battery
Lithium back-up battery
Lithium back-up battery for power failure-proof buffering of the data stored in the RAM.
Continuous buffer time, approx. 3-5 years. Type CR2032/3V,
230 mAh, plugged in, service life approx. 10 years
Changing the battery is permitted when live.
To retain the data in the unit when changing the battery, the power supply to the unit must remain switched on.
Please perform this work with great care to avoid triggering a short-circuit. Do not use any metallic tools for this work.
5.1.3 Replacing the back-up battery
Insert the battery vertically in the holder. To change the battery, push the power failure safety lock to the side. The battery can then be easily removed from the holder.
The new battery can also be pushed into the holder by pushing the safety lock to the side. Please ensure the poles are correctly positioned.
5.1.4 RS232 service interface
The service interface is located on the front of the LANRTC.
The connection to a PC can be made using a null modem cable (Mat. no. 1900070520095) with 9-pin SUB-D plug connectors.
On the LANRTC, the service interface also has the function of the RS232 host interface.
