I am having trouble with the M1XIN Expansion board. I got it enrolled into the system, but it will not properly recognize the sensors I've tried to add to it. Its connected to the M1DBH and is properly terminated using the plug. I've rewired all the connections to rule out wiring problems, and I've tried the sensors on the main board, and they all work. It just lists each sensor as violated, with no voltage or anything. I've tried a glass sensor and a water sensor. Any ideas or do I just have a bad board?
