Wiring and Connections	Section 3-4

The following diagram shows the wiring in the RS-422 cables used to connect CPM1A PCs to a 3G2A9-AL004-E Link Adapter. In both the Link Adapter/ RS-422 Adapter connections and the RS-422 Adapter/RS-422 Adapter connec- tions, connect the SG, RDA, RDB, SDA, and SDB terminals to the same termi- nals in the other Adapter.

3G2A9-AL004-E Link Adapter

9-pin D-sub Connector

25-pin D-sub Connector

Use a straight RS-232C cable to connect to the host computer’s RS-232C port.

Signal Pin no.

Note 1. The maximum length of the RS-422 cable should be 500 m.

2.Set the termination resistance switch to “ON” (upper side) for Adapters on both ends of the Host Link system.

Always use crimp connectors when wiring the RS-422 Adapters. Use M3 termi- nal screws and tighten the screws securely to the torque of 0.5 N S m.
