Does anyone know anything about the Trane LCI card? We are involved in a project where Trane has furnished these cards as a LON interface to their control boards on RTU's. The cards are networked on a LON bus. We can see the cards, but the data field in each controller appears to be locked out, preventing a successful interface with the RTU's. Is this the case where Trane only makes controllers that talk to Trane controllers? Suggestions?? Any help would be appreciated.
