OMRON Cables with Connectors
The OMRON cables listed below can be used when connecting with a method
other than the RS-232C communications method.
Model Cable Length
XW2Z-200S 2 m
XW2Z-500S 5 m
XW2Z-200T 2 m
XW2Z-500T 5 m
The OMRON cable listed below can be used when connecting to a personal
computer using RS-232C communications.
Model Cable Length
XW2Z-S002 2 m
The cable's tensile load is 30 N. Do not subject it to loads greater than this.
Otherwise a discontinuity may occur, causing operation to fail.
Applicable Units: C200H-LK201-EV1
CV500-LK201 (communications port 1)
Compatible cables with attached connectors:
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) below.
