4-3 Connections

4-3-1 Types of Connection

Port connections for Host Link communications are shown in the following table.

Up to 32 nodes can be connected for 1:N connections.

				Resistance ON

Note 1. Four-wire connections must be used for RS-422A/485 connections with Host Link communications.

2.“Resistance ON” indicates the terminating resistance must be turned ON.

3.“5-V power” indicates that a 5-V power supply is required for the Link Adapt- er. Refer to the Link Adapter manual for details. A 5-V power supply is not required for a Link Adapter connected to a Serial Communications Board because power is supplied from pin 6 of the connector.

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

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.
