I have Universal MX-3000 remotes all over the house that using a MSC-400 send serial commands to the OMNI. The system worked great for years until X10 just completely quit altogether. I never tried to use the remotes to control anything for years since the X10 was so problematic. Now I want to use HomeSeer and Z-Wave to solve that problem.
But I cannot seem to get the basic setup of the serial communication working again between the MSC-400 and the OMNI. I verified the cable and connection using my server that has PC Access and I can connect to the panel using serial connection just fine. I set Serial 1 to 9600 and Omni-Link and the Serial Address to 0. PC Access works just fine. Then I tested the serial connection from the MSC-400 to a laptop using a serial-to-USB and it communicates just fine, every time I hit a button, I get the text command.
The cabling I'm using is the same I've been using for years and I have been using the same cabling for testing and it seems to be working fine. Am I missing something in the Setup?

I'm using the BEEP 1 for testing to make the consoles beep when it does receive a message. The message here is GR LAMP ON.
