PRODUCT INFORMATION RFL 9850 TX Programmable FSK Tone Transmitter .-------- NOTE -----,----, The RFL 9850 TX requires the use of the RFL 9800 DSP Programmer to set its operating parameters. Before attempting to program the RFL 9850 TX for the first time, be sure to fully read the programming instructions starting on page 4 of this Instruction Data Sheet. Additional information on the RFL 9800 DSP Programmer can be found in its Instruction Data Sheet (Publication No. ID 103000). DESCRIPTION The RFL 9850 TX (Fig. 1) is a fully-programmable FSK tone transmitter. It can be programmed to operate on any standard center frequency from 300 Hz to 3200 Hz, with frequency shifts up to 300 Hz and at speeds up to 600 baud (2F operation only). The RFL 9850 TX uses Digital Signal Processing (DSP) tech­ niques to replace the discrete oscillators, modulators, and filters normally used in FSK transmitters. The RFL 9850 TX's operating characteristics can be changed by using the hand-held RFL 9800 Programmer to modify the software. This means its operating characteristics cannot be modified by unauthorized personnel. 0 RTS 0 CTS 0 SP IN 0 MK IN @HI C OUT ©) LO 0 0 0 O 0 0 0 0 0 0 0 0 0 0 98 TX SPECIFICATIONS As of the date this Instruction Data Sheet was pub­ lished, the following specifications apply to the RFL 9850 TX Programmable FSK Tone Transmitter.

This procedure can also be used to re-program the RFL 9850 TX any time a change in operating parameters is desired. An RFL 9800 DSP Programmer is required to do the programming. By only giving authorized personnel access to the programmer, all the RFL 9850 TX's operating parameters can be set and unauthorized personnel cannot change them. Push the RFL 9850 TX module all the way into the front of the chassis, and then use a flat-blade screwdriver to turn the two quarter-turn fasteners to secure the module in place. The RFL 9850 TX is now installed. CALCULATING SERIES RESISTOR VALUES FOR THE ISOLATED INPUT KEYING OPTION --����-NOTE When the RFL 9850 TX is equipped with the isolated input keying option, the MARK IN, SPACE IN, and RTS inputs are fed through optical isolators. These isolators normally require de input voltages between 5 and 1O volts for proper operation; they are equipped with current limiting resistors and clamping diodes for protection against reversed input polarities. If keying input voltages higher than 15 volts are to be used, ad­ ditional resistance must be added to the keying input lines external to the chassis. The following formula is used to determine the proper series resistance: During most programming steps, the [INCR] and [DECR] keys will change the parameter number; during dynamic set steps, they will affect the programmed YfilY..e. Parameters may be stepped (rather than entered) with these keys. The following procedure is used to check the settings of all programmable parameters and change them if necessary. Tables 3 and 8 list all the parameters programmed Ea - 9.75 during this procedure, and the entries that are valid for each parameter.

Plug. the RFL 9800 DSP Programmer's ribbon cable into the mating connector at the front of the RFL 9850 TX. 3. 10. Using the keypad, enter the desired Clear-ToSend delay. This is the amount of time in mil­ liseconds between the detection of a Request-To-Send (RTS) signal and the activation of the CTS output; it can be set to any value between 0005 (5 ms) and 0255 ( 255 ms). Note the status of the programmer's display. The parameter display should read "TXBW" (Transmitter Bandwidth), fol­ lowed by a four-digit number in the variable display. If it doesn't, press the [RESET] key. 4. 11. Press the [ENTER] key. The parameter display will read "TXMP .. (Transmit MARK Polarity), followed by a four-digit number. Using the programmer's keypad, ·enter the desired transmitter bandwidth. Valid choices are as follows: 0050- 50 Hz 0060 • 60 Hz 0085• 85 Hz 0120- 120 Hz 02 40-240 Hz 0300- 300 Hz 0600• 600 Hz 5. 6. 12. Using the keypad, enter the value for the desired transmit MARK pola.rity value. The transmitter section has two data in­ puts: MARK IN and SPACE IN. Both are used during 3F operation; only MARK IN is used for 2F operation. The TXMP parameter controls how the RFL 9850 TX will respond to various MARK IN/SPACE IN input level combinations. Press the [ENTER] key. The parameter display will read "TXCF" (Transmit Carrier Frequency), followed by a four-digit number. Valid settings for this parameter are 0000 and 0001. Table 4 lists how the RFL 985 0 TX will respond to each of these settings. For either setting, the MARK IN and SPACE IN indicators on the front panel will light when a logic one is present at the input; they will go out when a logic zero is present. Enter the desired transmit carrier (center) frequency using the keypad. The transmit carrier frequency can be any frequency between 300 Hz and 32 00 Hz that is compatible with the selected transmit channel bandwidth. For example, if the bandwidth was set to 300 Hz during step 4, the carrier fre­ quency cannot be set to 400 Hz; this would result in a low frequency of 2 50 Hz, which is beyond the range of the RFL 985 0TX. 7. 8.

Block diagram, RFL 9850 TX Programmable FSK Tone Transmitter Basic Operating Modes While in this mode, the parameter value will flash on the programmer's display. By pressing the [INCR] and [DECR] keys on the programmer, the transmitter out­ put level can be changed to any value between -40 dBm and O dBm. Each time the [INCR] or [DECR] keys are pressed, the output level will change by 0.25 dB; holding a key down will cause the level to change in 0.25-dB steps until the key is released. The RFL 9850 TX has two basic operating modes: the normal operating mode (RUN), and the Transmitter Set Mode (TXST). Normal Operation (RUN Mode): During normal operation, the transmitter section continuously monitors the MARK, SPACE, and RTS inputs. These in­ puts are used to control the output frequency of a waveform generator located in the DSP microcom­ puter. The output of the waveform generator is sub­ jected to a sine conversion routine, and then a filter routine. Once the desired output level is displayed, the user presses the [ENTER] key to store the new value in the programmer's RAM memory. Input Sampling The resultant filtered sine wave is multiplied by a con­ stant to set the fine output level. The DSP microcom­ puter periodically sends the sine wave to a digital-to­ analog (DIA) converter; this sampled sine wave is smoothed by an analog reconstruction filter before being passed to a digitally-controlled attenuator, where coarse level adjustments are made. The signal then goes to a voltage-to-current converter, which is used to drive the line. II The transmitter section's sampling period is 128 µs. MARK, SPACE, and RTS inputs are received by three line receivers in quad RS-232 line receiver U22. Op­ tional pull-up or pull-down resistors allow the user to tailor the input voltage threshold levels to the voltages that are present at the installation. This forms the data input interface (INTFIN). In a two-frequency mode of operation (2F), microcontroller U14 samples the MARK input four times during every sampling period, or once every 32 µs; the RTS line is sampled once every sam­ pling period, and the SPACE line is ignored. All data input lines are checked once every sampling period during three-frequency (3F) operation. The microcontroller assembles these data samples into a data byte. II Current drive allows several channels to be mixed onto a single line without isolating filters. The line must be terminated with a 600Q resistor to develop the proper voltage. Transmitter Set Mode (TXST): The transmitter set mode allows the user to activate the transmitter sec­ tion of the RFL 9850 TX and vary its output level.

(973) 334-3100 Because RFL™ and Hubbell® have a policy of continuous product improvement, we reserve the right to change designs and specifications without notice. Digital Signal Processing At the beginning of each sampling period, microcontroller U14 requests the attention of digital signal processor U13 and informs it of the status of all the data input lines. U13's operating program incre­ ments the oscillator phase, according to the state of the MARK and SPACE bits. An algorithm converts the phase into the digital equivalent of a sine wave. This sine wave passes to a filter algorithm; the output of this algorithm is multiplied by a constant which con­ trols the transmitter output level. DIA Conversion And Filtering The processed digital FSK signal is transferred back to U14 at the start of the sampling period as two bytes. U14 massages the bits in this signal and transfers them as serial data to the D/A converter input of CODEC U15. The anaiog output of U15 is a stepped wave; it is smoothed by a switched-capacitor low-pass filter in U8. The output of this filter is passed through digitally­ controlled potentiometer U7, which provides a coarse signal-level adjustment. The signal then passes to a bandpass filter in U8. This second filter removes addi­ tional spurious tones. If U14 finds that the programmer is not present, it goes to a setup routine, which initializes U 14 and digi­ tal signal processor U13. Once both devices are initial­ ized, U14 obtains the system operating parameters from U3. These parameters control coefficients and branching within U14 and U13; the parameters that control U13 are passed from U14 to U 13 over their direct interface. After the parameters are distributed, some additional initialization steps are performed, and then the module enters the RUN mode, where it will remain until reset. If U14 finds that the programmer is connected to the programmer port, it initializes for programming, trans­ fers U3's contents to the programmer, and enters a loop to wait for instructions from the programmer. The user can then use the programmer to view all the parameter settings, and change them if necessary. The RFL 9850 TX is idled during programming; when programming is completed, U14 accepts the new set of parameters from the programmer and writes them into U3. U14 then distributes the new parameters to itself and U13, and enters the RUN mode using the new parameters. If further programming needs to be done, the programmer can regain the attention of U14 by issuing a hardware reset; this is done when the user presses the [RESEn key in the keypad. r------- NOTE ----___, Throughout the following software description, signal names appear in CAPITAL letters. Inverted or active-low signals are indicated by an asterisk after the signal name (WR*, BIO*, etc). Voltage-To-Current Conversion The voltage output of U8 is applied to the input of operational amplifier U9. U9 acts as a voltage-to­ current converter to produce the current used to drive the line. U9 has a compliance of ±9 volts, which means that signals with a combined power of up to 18 dBm can be mixed on a 600Q line, assuming that the carrier level is less than O dBm. The output is coupled to the line by coupling transformer T2. Programmability SOFTWARE DESCRIPTION The heart of the RFL 9850 TX is digital signal processor U13, which is under the control of microcontroller U14. U14 controls all timing functions and all data transfers into and out of U13. Timing synchronization is achieved by activating U13's BIO* input (pin 9). Data is passed from U14 to U13 as eight-bit bytes; U13 combines these bytes into 16-bit words. Programmability is provided by U3, which is a non­ volatile Electronically Erasable Programmable Read­ Only Memory (EEPROM). When the RFL 9850 TX is first turned on, microcontroller U14 interrogates the programmer port to check whether the RFL 9800 DSP Programmer is connected to the module. RFL 9850 TX February 3, 2000 Power-Up Reset At power-up, U14 receives a hardware reset, and it sends a reset to U13. U13 then sends an identification code back to U14. This code informs U 14 of the cur­ rent hardware and software environment; it needs this information because its operating software contains code for several modules in the 9800 Series, and it 9 RFL Electronics Inc. (973) 334-3100 Because RFL™ and Hubbell® have a policy of continuous product improvement, we reserve the right to change designs and specifications without notice. must know which code to use. If the RFL 9800 DSP Programmer is connected to the RFL 9850 TX and the RFL 9850 TX is not running, U14 sends a "keep-alive" code to U13. U13 will then enter a loop and wait for a reset from U14. U14 resets U13 at regular intervals, in­ itiating the "READ" operation that strobes U13's DEN output (pin 32). This prevents the watchdog timer from resetting the module. the data registers that Will be used during the RUN mode of operation. Data memory locations containing constants needed for running are re-initialized, and U13 proceeds to the RUN phase of its program code. When the RFL 9850 TX enters the RUN mode or one of the four dynamic set modes controlled by the RFL 9800 programmer, U14 reads the data stored in EEPROM U3 and sends U13 the data it needs to operate. U13 stores each byte of data in its memory and echoes it back to U14. If the echo is not valid, U14 will reset U13 and start the data transfer again. Once all the data has been successfully transferred (with valid echoes), U13 starts the initialization phase of its program code. Synchronizing BIO* signals initiate the exchange of information between microcontroller U14 and digital signal processor U 13 (the DSP). During each sampling period, two pieces of information are exchanged: the transmitter output level into CODEC U15, and the ter­ minal input vectors that contain information on data and carrier status. Microcontroller-To·DSP Data Exchange Transmitter Control In its initialization pha�e, U13 loads a set of constants into its memory and then computes and saves the phase increment values needed for the desired center, MARK, and SPACE frequencies; if the 2F transmit mode has been selected, the center and SPACE fre­ quency phase increments are equal. These phase incre­ ments represent the amount by which the phase of the FSK oscillator will advance for each quarter of the sam­ pling period. U13 then determines the filter coeffi­ cients required by the transmit bandpass filter, and loads them into data memory. The bandpass filter has an equiripple group delay in its passband to minimize pulse distortion. Its primary function is to limit the sideband energy of the FSK carrier that would fall into adjacent channels; the frequency spectrum of the keyed carrier is kept well within CCITI limits. The running code begins with the computation of the FSK oscillator frequency for the transmitter section. The basic DSP sampling period is 128 µs; for high­ speed data (such as 600 baud, where the period of one bit is 1667 µs), discrepancies caused by the fixed sampling times could amount to nearly 8 percent of a data bit; this would produce excessive jitter in the data stream. To keep jitter within acceptable limits, U14 samples the input data status four times every sam­ pling period. The terminal input vector passed to U13 indicates data status for each quarter of the previous sampling period, and U13 uses this information to make any required adjustments to the phase increment of the FSK oscillator. The generated phase ramp is es­ sentially a triangular wave, which is converted into a sinewave by an algorithm and then passed through a bandpass filter. The conversion to a sine wave eliminates distortion products which might otherwise alias back into the filter passband. The transmitter gain factor is then computed, based on the dB values entered by the user using the RFL 9800 programmer. After the gain factor is computed, U13 computes a few more running parameters and clears After filtering, the amplitude of the FSK signal is fine­ adjusted in quarter-dB steps; coarse adjustment is a hardware function performed by digitally-controlled potentiometer U7.
