The CIM is where all field connections, such as RS485, EXV and analog/digital wiring, is made to
communicate with the compressor. As previously stated, there are two (2) variants of the CIM.
Revisions A and B do not contain the connector numbers on the front plate (e.g., J5). The "Pin 1"
indicators are also not present on the A and B revisions.
