External Connection

This chapter describes the interface connectors on the board and the external I/O circuits.
Check the information available here when connecting an external device.

Using the On- Board Connectors

Connecting a Board to a Connector

Use the optional connection cable (CNT-68M/50M or PCA68PS-**P, PCB68PS-**P) to connect the
board to an external device. Uses the cable together with a terminal block for the wiring between the
board and external device.
