3.3.6 I/O Expansion Board (MCTC-KZ-G1)
The expansion board (MCTC-KZ-G1) has one RS458 interface, one CANbus communi-
cation interface, ten DI and ten DO terminals. The expansion board is connected to the
CAN1 bus of the control board via the CANbus interface to implement I/O terminal ex-
pansion. The CAN1 bus supports up to two expansion boards, one of which is placed
in the equipment room and the other at the top of the car. The DIP switch on the
expansion board is used to set an address. When all switches are OFF, this board is at
the top of the car. When switch 1 is in 1 position, this board is in the equipment room.
The terminals of the expansion board are allocated with functions in FD-11 to 50.
