  back to top

so i have a test rig set up
mimics the file i sent you
on UCM1 (the centralite UCM) ( RS232 daughter board in place but NO RS232 'load") D11 D12 DO NOT flash when I send an RS232 command.
Howeveron UCM2 (the network UCM) D11 D12 DO flash when I send an RS232 command.

Does the RS232 command get sent universally to all boards and only flashes if it sees an RS232 handshake (even though the response is addressed to only a SINGLE UCM !).
