ST600 TRANSMITTEROPERATING INSTRUCTIONS1892 1273PL1 PL3PL2Figure 1 Physical ArrangementThese operating instructions are intended to provide the user with sufficient informationto install and operate the unit correctly. The Wood and Douglas ST600 UHF transmitter is intended to fulfil the numerous OEMapplications by virtue of its highly flexible synthesized design approach, miniature sizeand cost-effective performance. The transmitter can accept analogue and digital datainput and provides an RF output power of 125mW (adjustable down to 1mW, refer toSales Office for details). INSTALLATIONNOTES: Pin spacing on all connectors is 2.54mm (0.1")All dimensions in millimetresFor 7 pin connector version position is shown dotted.
TXECONNECTIONConnection to the ST600 transmitter is via PL1, PL2 and PL3 which plug directly intothe user's own equipment. The location of these connectors is shown in Figure 1 anddetailed in the following tables. (The unit is fitted with a 10 pin connector when parallelfrequency select facility is provided).PIN NAME FUNCTION REMARKS10V 0 volts common ground2RF O/P RF output 50 ohms output30V 0 volts common groundConnector PL1 pin detailPIN NAME FUNCTION REMARKS1+VIN positive supply +6.0V to +15.0V20V 0 volts common groundConnector PL2 pin detailPL1PIN NAME FUNCTION REMARKS10V 0 volts common ground2transmit enable o/c = transmitter disabledLOW <+0.5V = transmitter enabled1k nom. internal pull-up to +Vin3DIGITAL I/P data input 0/+3V to 0/+12V, DC-coupled4ANALOGUE I/P data input > 50 mV p-p, AC-coupled5+5VOUT + 5 volt supply output 50mA maximum current drain6RS232 I/P serial programmingi/p RS232 level programming inputNote: Inverted TTL data can also be used.If not used, leave not connected, orconnect to 0/V70V 0 volts common ground8RB1 parallel frequencyselect internal pull-up to +5V, active low9RB210 RB3Connector PL3 pin detail
Figure 2 Programming AdaptorFREQUENCY PROGRAMMINGThe ST600 has an internal memory which can store up to 128 RF channels (16randomly programmed and 112 sequentially programmed). The frequency and set-upinformation is programmed into the unit by a synchronous PCM interface protocol.The software supplied with the ST600 transmitter is the STSRn00.exe program. Thesoftware can be run on a PC with the serial port connected to PL1 of the ST600transmitter via a suitable adaptor as shown in Figure 2. If the read-back function isdesired, then PL1 pin 10 of the transmitter must be connected to pin 2 of the PC serialport via a buffer circuit. A 1k pull-up resistor to +5V must also be provided as shown.
RUNNING THE SOFTWARE1. Connect ST600 to a suitable supply and to the PC using the programmingadaptor.2. Insert the STSRn00.exe 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 isused to communicate with the ST600 receiver. Enter 1 or 2.4. Next there is a prompt to select STn00 or SRn00. Enter 1 for the ST6005. 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 shownin 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 STORAGEThe internal PIC processor allows for both random allocated frequencies andsequential channels. The program displays the 16 (as channel 0/ to 15) randomchannels on the main screen. If a sequential table is used then these are stored inchannels 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 tothe random 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 toFigure 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 selectionThe unit defaults to serial channel selection whenever the software is run. Selectingthe F7 function key prompts the user to enter the new serial channel number which isthen displayed in ‘Serial channel selected’.
Parallel channel selectionTo 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 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 arrowkeys and then entering the required operating frequency. The entered value must bean integer multiple of comparison frequency otherwise an ‘invalid’ message isdisplayed.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 willbe increased automatically.When the frequency table has been generated the user then selects F6 to program theunit, 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.
