3.5mm to RS232 adapters have given me trouble with alarm panels.
I've also had issues with long RS232 runs(Over 10-15')
For these reasons, I always run a Global Cache IP2RS232 iTach for alarm panels now. Ethernet to the panel/itach then HSIM or 4232CBM connected right to the itach.
The EA-1 location used to be a GlobalCache IP2SL device. Had the same issue and tech support said change over to an EA-1. Ugh.
