MC-LSI Landing System Interface Board
The MC-LSI mounts in the cartop box and provides a connection point for the landing system
and for the Car Panel Interface board (MC-CPI) if one is used. The MC-LSI board receives 24
VAC power from an external transformer operating from the controller 2 Bus (120 VAC). In
turn, the LSI board provides power to the landing system and to any Universal I/O boards that
might be used on the cartop through the CAN connections to those components. A shielded,
external CAN connection runs from the LSI board, through the traveler, to the Motion 2000
controller.
