5.1.3  Channel Selection via DIP
Switches
The backplane-mounted DIP switch settings
override the default channel programmed by
PGM800Win.
To set a default channel via the software, all
DIP switches must be set to “OFF” (i.e.
00000000).
When a switch is “Off”, its binary count is ac-
tive; when a switch is “ON” its binary count is
inactive. The various DIP switch combinations
of ON or OFF make up a binary total, which
identifies the channel number.
To select a channel, set the appropriate DIP
switch or switches to “OFF” to make the binary
count total the channel number you want. Set all
other switches to “ON”.
It is recommended to set both SW1 (RX) and
SW2 (TX) to the same settings on both back
plane boards.
Example: To select channel 5, set the DIP
switches as shown below:
