I have an EZbridge, the plm, and the 2×4 input module. When I connect to EZbridge everything is fine. When I put in the module id of the 2×4, the utility tries to get data 4 times and times out. I can see valid responses coming through on the ezbridge log. It seems that the software is not responding to valid responses. Also where can I get the function codes to talk to the 2×4 manualy via xml?
