Just to eliminate the obvious. Do you have power connected to both the controller and and relay pack? Usually the you plug power into the relay pack, and the controller gets power down the serial cable (when hooked up as a wired configuration). Some people don't realize that when you use the wireless pack, that you need to hook up seperate power feeds to both units. Also, I believe what AMP says is true about compatability, but I believe there is a way to make it work. I'll let "Support" field that one.
Once you eliminate the obvious, call support at 800 322 6337, and they can either tell you whats wrong or recommend a fix if it is possible between the ADJ/LSC compatability issue.
