Note 1. The maximum cable length for RS-232C is 15 m.

2.The maximum combined cable length for RS-422A/485 is 500 m including branch lines.

3.The maximum cable length is limited to 2 m when an NT-AL001-E Link Adapter is connected.

4.Branch lines must be a maximum of 10 m long.

Connection Examples

The connection examples in the remainder of this section show only the basic connection diagrams. We recommend that appropriate noise countermeasures be taken in actual applications, including the use of shielded twisted-pair cables. Refer to 2-3 Wiring for actual wiring methods.
