3.5.6 Programming Sequential Channels
To generate a new frequency table the following parameter values must be entered:
- start frequency
- the maximum frequency
- the table step as a multiple of 12.5kHz.
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.
The function key F2 can be used to copy the contents of channel 16-31 to channel 0 - 15
to ease sequential programming.
3.5.7 Programming from Customer Equipment
In the event of a customer wishing to program the ST500 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 interface, 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
