Agree with Lincoln on this one.? I would set it up to control the DMPS
units with rs232 like an external device, rather than an internal
device.
You could make a simple program for the DMPS that get's
loaded into all of them, that has a custom rs232 protocol implemented to
perform local actions on the DMPS unit, and then sends feedback back
out the rs232 port (if you need status feedback or anything).
Then
your main controller in each room, would just send out commands based
on your implemented protocol to a single rs232 port on the AV3, and it
wouldn't matter which DMPS was plugged in, as the DMPS would receive the
RS232 command and the local DMPS program would perform the requested
action locally and send any necessary feedback back to the AV3.
This
would be simple especially if your only controlling switching on the
DMPS.? But would still work even if your controlling IR devices locally
on the DMPS as well, just a bit more protocol to implement.
