Wiring Section 3-3
Connection Examples
The connection examples in the remainder of this section show only the basic
connection diagrams. We recommend that appropriate noise countermea-
sures be taken in actual applications, including the use of shielded twisted-
pair cables. Refer to 3-4 RS-232C and RS-422A/485 Wiring for actual wiring
methods.
