There are actually two panels in the project.
1. EA-1 with a 6' cable to the HSIM, and then a 2' run of security cable from the HSIM to the panel.
2. IOX with a 30' cable to the HSIM, and then a 2' run of security cable from the HSIM to the panel.
The issue occurs on both panels (though not at the same.)
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.
