■ Cable connection example
<Connection with DOS/V PC>
Connect the upstream controller to the CIDRW controller using the cable whose configuration is speci-
fied below. Limit the whole cable length to 15 m.
*1 Ground the shielded cable either on the PC/AT side or CIDRW controller side.
*2 The controller can run without a wiring between RS and CS. Note, however, that a wiring connec-
tion from RS to CS(*2-2)enables verification of correct connection with the CIDRW system. Fur-
thermore, with an additional connection from RS to CS(*2-1),the directionality of cable will be lost.
• Recommended cable: CO-MA-VV-SB 5PX28AWG (Hitachi Cable, Ltd.)

Recommended connector: socket-Model XM2D-0901 (OMRON), hood-Model XM2S-0913 (OMRON)
