ran a TECC command as well--That was part of the troubleshooting flowchart for a CAN communications failure. Placed the system in inspection mode and ran the TECC command followed by DCN. It shows node 0 offline, 1 online, and 2 offline. None of the jumpers were changed, so the node addressing should be correct as well. --My concern is the fact that the top floow and the bottom floor the lights don't light up, even momentarily, but the middle floor both buttons work to call the elevator.


I appreciate everyone's help and quick replies. It's always fun troubleshooting through a forum
