Connectors and Cables Recommended for RS-422A/485

When making an RS-422A/485 connecting cable, as far as possible use the recommended parts indicated in the table below. When using the memory link method, however, use a connector that matches with the RS-422A port at the CPU Unit (CP) side. Some Units come supplied with one connector and con- nector hood.
