The command that HG is sending looks correct. The problem is that the module does not trigger. AHP connected to a second CM15A on a PC located in my office shows the following for that event:
7/25/2014 19:27 Receive O1
7/25/2014 19:27 Receive O Off
7/25/2014 19:27 Receive B On
So HG thinks it's sending the full command, but something isn't working. The sequence should be:
7/25/2014 19:27 Receive O1
7/25/2014 19:27 Receive O Off
7/25/2014 19:27 Receive B1
7/25/2014 19:27 Receive B On
The B1 command is getting lost somehow. It's either because of issues with the setup of hardware (noise, signal sucker, etc) or with the signal (HG is sending the command too close to the O1 Off being received, something else). I can play with the hardware to isolate things, but I was looking to see if giving a longer pause between commands might help.
The issues is that this happens occasionally but not in a way that I can currently cause manually. IOW, I don't know how to make this happen so I don't know how to easily debug it yet.
