Omron NT631C manual Wiring for a Host Link Unit 25-pin Connection, Serial Port A, B

Connecting to the RS-232C Port at the Host Section 4-1

Note

Wiring for a Host Link Unit (25-pin) Connection

When a connection is made to a personal computer at serial port A in the memory link method, OMRON cable with connectors shown below are avail- able.

Model	Cable Length	Connector Specification
CV500-CN228	2 m	9-pin ⇔ 25 pin
XW2Z-S002	2 m	9-pin ⇔ 9 pin

The cable’s tensile load is 30 N. Do not subject it to loads greater than this.

Applicable Units: C200H-LK201-EV1 3G2A5-LK201-EV1 C500-LK203 3G2A6-LK201-EV1

CV500-LK201 (communications port 1)

Cables with connectors that can be used at serial port A:

XW2Z-200S (9-pin ⇔ 25-pin, 2 m)

XW2Z-500S (9-pin ⇔ 25-pin, 5 m)

CVM1/CV-series Host Link Units (CV500-LK201) have two types of connec- tor; a 25-pin connector (communications port 1), and a 9-pin connector (com- munications port 2). When using communications port 2, refer to Wiring for Other Connections (Other Than the Memory Link Method) (page 75).
