SR600 RECEIVER OPERATING INSTRUCTIONS These operating instructions are intended to provide the user with sufficient information to install and operate the unit correctly. The Wood and Douglas SR600 UHF synthesized receiver is intended to fulfil the numerous OEM applications by virtue of its highly flexible synthesized design approach, miniature size and cost-effective performance. INSTALLATION NOTES: Pin spacing on all connectors is 2.54mm (0.1") All dimensions in millimetres CONNECTION Connection to the SR600 receiver is via PL1, PL2 and PL3 which plug directly into the user's own equipment. The location of these connectors is shown in Figure 1 and detailed in the following tables. PIN NAME 0V RF I/P 0V FUNCTION REMARKS 0 volts common ground RF input 50 ohms input 0 volts common ground Connector PL1 pin detail PIN NAME +VIN 0V FUNCTION REMARKS positive supply +6.0V to +15.0V 0 volts common ground Connector PL2 pin detail PIN NAME FUNCTION RSSI S meter output SQF Squelch flag AUDIO AF output DATA REMARKS 0.5 - 2V signal strength indicator, 60dB range open collector output, ON (low) = no signal 250mV p-p ±20% into 10kS Note: The output audio is inverted with respect to the ST600 (or similar Wood & Douglas product) audio input. Data output open collector, no pull-up Note: The data output is inverted with respect to the ST600 (or similar Wood & Douglas product) data input. +5V +5 volt supply output 50mA maximum current drain 0V 0 volts common ground RS232 serial programming I/P input RB1 RB2 10 RB3 parallel frequency select RS232 programming input Note: inverted TTL level data can also be used. If not used, leave not connected, or connect to 0/V internal pull-up to +5V, active low Connector PL3 pin detail FREQUENCY PROGRAMMING The SR600 has an internal memory which can store up to 128 RF channels (16 randomly programmed and 112 sequentially programmed). The frequency and set-up information is programmed into the unit by a synchronous PCM interface protocol. The software supplied with the SR600 receiver is the STSRn00.exe program. The software can be run on a PC with the serial port connected to PL3 of the SR600 receiver via a suitable adaptor as shown in Figure 2. For the read-back function PL3 pin 10 of the receiver must be connected to pin 2 of the PC serial port via a buffer circuit. A 1k pull-up resistor to +5V must also be provided as shown. Figure 2 Programming adaptor RUNNING THE SOFTWARE 1. 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:STSRn003. The user is then prompted to enter the serial port number of his PC which is used to communicate with the SR600 receiver. Enter 1 or 2. 4. Next there is a prompt to select STn00 or SRn00. Enter 2 for the SR600 5. 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 in Figure 3. The screen shows the default settings which are entered at factory set-up. These default settings will be displayed whenever the STSRn00 software is run. Please note that mouse operation is not supported with this program. FREQUENCY STORAGE The internal PIC processor allows for both random allocated frequencies and sequential channels. The program displays the 16 (as channel 0/ to 15) random channels on the main screen. If a sequential table is used then these are stored in channels 16 to 127. These cannot be displayed or printed out. To simplify the situation, the first 16 channels of the sequential table can be copied to the random channel by pressing the F2 button. The first 8 channels (0 to 7) can be selected using the serial interface or the parallel interface, as described later.

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 Figure 2). 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 selection The unit defaults to serial channel selection whenever the software is run. Selecting the F7 function key prompts the user to enter the new serial channel number which is then displayed in ‘Serial channel selected’. Parallel channel selection To enable parallel channel selection mode press the F4 (Parallel channel mode) function key, 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 CHANNEL LOW LOW LOW LOW LOW HIGH LOW HIGH LOW LOW HIGH HIGH HIGH LOW LOW HIGH LOW HIGH HIGH HIGH LOW HIGH HIGH HIGH The logic levels are : LOW < 0.8V HIGH > 2V or floating Programming random channels Random channels between 0 and 15 can be entered using the Up 8 and Down 9 arrow keys and then entering the required operating frequency. The entered value must be an integer multiple of comparison frequency otherwise an ‘invalid’ message is displayed. Programming sequential channels To 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 be increased 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 to ease sequential programming. Programming from customer equipment In the event of a customer wishing to program the SR600 receiver from his own equipment then the following data sequence must be used allowing 5ms between the characters in the data stream: 1200 baud, RS232 levels, 1 start bit - 8 bit data - no parity - 1 stop bit 40 (decimal 64) synchronising code 7 bit channel 0 - 127 (bit 7 = 0) 95 (decimal 149) confirmation byte RANGE INFORMATION The following table gives an indication of the typical ranges to be expected between a transmitter and receiver that have simple end-fed dipole antennas. The following assumptions have been made in the calculations: line-of-sight between antennas 0dB gain for the transmitter and receiver antennas 0dB loss for connectors and cables between the antenna and the radio connector 20dB fade and environmental margin -100dBm received signal strength, allowing for digital and analogue signals Range versus TX power Frequency (MHz) Power (mW) Power (dBm) Range (km) Miles 600 1mW 0.4 0.3 600 10mW 10 1.3 0.8 600 25mW 14 2.0 1.2 600 100mW 20 4.0 2.5 600 500mW 27 8.9 5.5 TECHNICAL SPECIFICATION Frequency range Switching bandwidth Frequency stability Number of RF channels Channel switching delay Channel spacing Modulation type Spurious emissions (conducted & radiated) Supply voltage Supply current at 7.2V Interface connections RF connection Operating temperature Storage temperature Weight Size Type approval Sensitivity Image/spurii Intermodulation response rejection Blocking Intermediate frequencies Adjacent chan. selectivity Audio response Recovered audio level Squelch type General facilities 580 - 625MHz 8MHz +/-2.5ppm up to 128 (16 randomly programmed, 112 sequential), serial select/reprogram, 1200 baud RS232 or 1 of 8 parallel select (10 pin option) <50mS across switching bandwidth 25kHz F3D in accordance with ETS/CEPT specifications 6-12 DC, -ve earth <40mA 2 + 10 pin 0.1" header 3 pin 0.1" header -30oC to +55oC -30oC to +70oC 35g 60 x 39 x 15mm (2.36 x 1.53 x 0.59 inches) <-117 dBm for 12dB SINAD (25 kHz) (Measured with a flat audio response) >60dB >60dB >75dB 45 MHz and 455kHz >60dB for 12.5kHz channel spacing >70dB for 25kHz channel spacing 9Hz to 6kHz at -3dB (25kHz channels) >250mV p-p (±20%) into 10kS Noise operated open collector output RSSI output (0.5 to +2V nominal) +5V output Independent data output Wood and Douglas Ltd Lattice House, Baughurst Road, Tadley, Hampshire RG26 5LP Tel: +44(0) 118 981 1444.
