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.

Cable Length
CV500-CN228
2 m
XW2Z-S002
2 m
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).
