Here are some quick facts:
The LCI-X is a host based LonTalk interface board for Commercial Self Contained, Intellipak, Voyager, and Precedent.
The LCI-X replaces the current LCI-I and the LCI-R.
The LCI-X is an LCI-I that has been reduced to the size of an LCI-R.
The LCI-X uses the same software as the LCI-I when it is used as an LCI-I.
The LCI-X does not use the current LCI-R software. It requires new software to interface with the ReliaTel control.
The LCI-X has been released and is being used as an LCI-I at this time.
The LCI-X does not support communications to a Voyager UCP.
There is a Rover and LNS plug-in for the LCI-R, but not the LCI-I. That is the same for the LCI-X.
The LCI-X hardware is a direct replacement format for the ReliaTel system in the Precedent and Voyager rooftop units.
Problem
The new LCI board uses half wave rectification. IPAK-1 boards are all full wave. Need to buy another 50 VA 24 vac transformer and use it just for the new LCI. This way we can keep half wave and full wave boards electrically separate. We have lost RTM boards when the separate transformer was not used.
Note
Notice that 24 vac hot /neutral and the IPAK-1 IMC is on the same connector now.
Pins on the 4 pin connector: Pin 1 = +24vac; Pin 2 = 24 vac neut. Pin 3 = IPC +; Pin 4 = IPC neg >per wire color code black and white.
(If you do not see a software value at the end of config menu for this board, then switch polarity on IPC.)
