Serial Car Call Board
The MC-CPI-2 board, mounted in the car operating panel, converts the discrete closures from
the panel buttons and switches to serial data for the CAN bus. Unused spare inputs to and out-
puts from these boards are set to NOT USED at the factory. If a CPI-2 board is replaced in the
field or if controller software is upgraded, it is very important to check programmable CPI-2
board inputs and outputs and verify unused connections are set to NOTUSED. The CPI-2 board
is also responsible for landing system control. For additional information, please refer to
