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.
