Serial Port Multiplexer Board

One of the accessory board options available is the serial port multiplexer. This enables the
CNI2 serial data port to access two external devices (electronic correctors for example). Two
terminal blocks provide the connection point for serial data cable.
A metal base plate is included for the purpose of securing the board into position as seen in the
illustration.
