SR600 RECEIVEROPERATING INSTRUCTIONSThese operating instructions are intended to provide the user with sufficient information toinstall and operate the unit correctly. The Wood and Douglas SR600 UHF synthesized receiver is intended to fulfil the numerousOEM applications by virtue of its highly flexible synthesized design approach, miniaturesize and cost-effective performance. INSTALLATIONNOTES: Pin spacing on all connectors is 2.54mm (0.1")All dimensions in millimetres
CONNECTIONConnection to the SR600 receiver is via PL1, PL2 and PL3 which plug directly into theuser's own equipment. The location of these connectors is shown in Figure 1 and detailedin the following tables.PIN NAME FUNCTION REMARKS10V 0 volts common ground2RF I/P RF input 50 ohms input30V 0 volts common groundConnector PL1 pin detailPIN NAME FUNCTION REMARKS1+VIN positive supply +6.0V to +15.0V20V 0 volts common groundConnector PL2 pin detail

Figure 2 Programming adaptorFREQUENCY PROGRAMMINGThe SR600 has an internal memory which can store up to 128 RF channels (16 randomlyprogrammed and 112 sequentially programmed). The frequency and set-up informationis programmed into the unit by a synchronous PCM interface protocol.The software supplied with the SR600 receiver is the STSRn00.exe program. The softwarecan be run on a PC with the serial port connected to PL3 of the SR600 receiver via asuitable adaptor as shown in Figure 2. For the read-back function PL3 pin 10 of thereceiver must be connected to pin 2 of the PC serial port via a buffer circuit. A 1k pull-upresistor to +5V must also be provided as shown.
RUNNING THE SOFTWARE1. Connect SR600 to a suitable supply and to the PC using the programming adaptor.2. Insert the STSRn00PRG disk into drive A and type:A:STSRn00 <return> 3. The user is then prompted to enter the serial port number of his PC which is usedto communicate with the SR600 receiver. Enter 1 or 2.4. Next there is a prompt to select STn00 or SRn00. Enter 2 for the SR6005. Next is the prompt to select freq. range: 1 : ST100 (125 - 180MHz)2 : ST/SR500 (400 - 650MHz)3 : ST/SR800 (800 - 880MHz)After the software has successfully loaded the main menu screen is displayed as shown inFigure 3. The screen shows the default settings which are entered at factory set-up. Thesedefault settings will be displayed whenever the STSRn00 software is run.Please note that mouse operation is not supported with this program.FREQUENCY STORAGEThe internal PIC processor allows for both random allocated frequencies and sequentialchannels. The program displays the 16 (as channel 0/ to 15) random channels on the mainscreen. If a sequential table is used then these are stored in channels 16 to 127. Thesecannot be displayed or printed out.To simplify the situation, the first 16 channels of the sequential table can be copied to therandom channel by pressing the F2 button.The first 8 channels (0 to 7) can be selected using the serial interface or the parallelinterface, as described later.

Freq. 458.95 MHz Sequential frequencies, Chan. 16 to 127 Table step 1 x 12.5 kHzFigure 3NOTES:1. The reference (TXCO) frequency is not programmable.2. The readback function (F5) reads the current settings from the unit into the PC.3. Function F6 (program the unit) is only enabled after the read-back, (refer to Figure2). This function re-programs the unit connected.4. A value for each parameters has to be entered.5. Only channel 0 to 15 frequencies can be displayed by this software explicitly. 6. Sequential channel table is displayed as start, step and stop frequencies. Serial channel selectionThe unit defaults to serial channel selection whenever the software is run. Selecting the F7function key prompts the user to enter the new serial channel number which is thendisplayed in ‘Serial channel selected’.
Parallel channel selectionTo enable parallel channel selection mode press the F4 (Parallel channel mode) functionkey, The screen then displays ‘parallel channel selected’. Three inputs RB1, RB3 and RB3 applied via PL3 to pin 8, pin 9 and pin 10 respectively,select the operating channel as shown in the following table.CHANNEL SELECTION PIN 10 PIN 9 PIN 8 CHANNELLOW LOW LOW 7LOW LOW HIGH 6LOW HIGH LOW 5LOW HIGH HIGH 4HIGH LOW LOW 3HIGH LOW HIGH 2HIGH HIGH LOW 1HIGH HIGH HIGH 0The logic levels are : LOW < 0.8VHIGH > 2V or floatingProgramming random channelsRandom channels between 0 and 15 can be entered using the Up 8 and Down 9 arrow keysand then entering the required operating frequency. The entered value must be an integermultiple of comparison frequency otherwise an ‘invalid’ message is displayed.Programming sequential channelsTo generate a new frequency table the following parameter values must be entered:- start frequency- the table step as a multiple of comparison frequency.The maximum frequency is calculated from the start table frequency and the table step..Therefore if the calculation exceeds the maximum frequency then this parameter will beincreased automatically.When the frequency table has been generated the user then selects F6 to program the unit,assuming the unit has been read before.The function key F2 can be used to copy the contents of channel 16-31 to channel 0 - 15 toease sequential programming.
Programming from customer equipmentIn the event of a customer wishing to program the SR600 receiver from his own equipmentthen the following data sequence must be used allowing 5ms between the characters in thedata stream:1200 baud, RS232 levels, 1 start bit - 8 bit data - no parity - 1 stop bit40 (decimal 64) synchronising code7 bit channel 0 - 127 (bit 7 = 0)95 (decimal 149) confirmation byteRANGE INFORMATIONThe following table gives an indication of the typical ranges to be expected between atransmitter and receiver that have simple end-fed dipole antennas.The following assumptions have been made in the calculations:line-of-sight between antennas0dB gain for the transmitter and receiver antennas0dB loss for connectors and cables between the antenna and the radio connector20dB fade and environmental margin-100dBm received signal strength, allowing for digital and analogue signalsRange versus TX powerFrequency (MHz) Power (mW) Power (dBm) Range(km) Miles600 1mW 00.4 0.3600 10mW 10 1.3 0.8600 25mW 14 2.0 1.2600 100mW 20 4.0 2.5600 500mW 27 8.9 5.5
