Connecting to the RS-232C Port at the Host Section 4-1
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.
Note The cable’s tensile load is 30 N. Do not subject it to loads greater than this.

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).
