Serial Channel Selection (own equipment)
If you want to select a channel using serial mode from your own equipment rather than
using the supplied software, then you must use this protocol:
1200 baud, RS232 levels, 1 start bit - 8 bit data - no parity - 1 stop bit
and send the following data sequence to the RS232 input, allowing at least 5ms between
the characters in the data stream:
x40 (decimal 64) synchronising code
Channel number in hex (decimal 0 to 255)
x95 (decimal 149) confirmation byte
Any channel between 0 and 255 can be selected.
v Any serial communication with the unit disables parallel selection.
