I have a Trane BCU (BMTX) that stopped communicating over the LAN after a storm. There is no visable bamage that I can see but the LAN connection is no longer functional. If I unplug the CAT5 LAN cable form the BCU and plug a cable from my laptop to the BCU, I show activity in my taskbar like it's trying to connect but it never does. I have tried disabling IP connections in the BCU and tried to connect direct, but no luck. I think I have a hardware issue with the board. The BCU is still controling the building but you can't communicate with it.
Has anyone ever repaired the network connection part of a BCU (BMTX)?
