Hi Douglas,

I looked at the code a bit and I believe that their software uses a broadcast to find available modules even you specify the IP address of the module you want. The broadcasts won’t go between subnets.

>> You need to explain more.  When you change the detector from 10.2.101.34 to 10.2.103.31 are you also physically moving the detector to a different subnet?  Or are you simply changing the IP address.  If the the former, then is there a firewall between the 2 subnets?  If you are simply changing the IP address but not physically moving to another subnet then that is not going to work.
