Connectors and Cables Recommended for RS-422A/485
When making an RS-422A/485 connecting cable, as far as possible use the rec-
ommended 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 (CP) side. Some units come supplied with one connector and connector
hood.
Check the required parts and prepare them in advance.
