When using the host link or NT link (1:1), set the RS-422A send mode to continual sending (set both SW1-5
and 6 OFF).
When using the NT link (1:N), set the RS-422A send mode to complies with CS control of RS-232C (i.e., one of
SW1-5 and SW1-6 must be ON).

Using an RS-232C/RS-422A Adapter
(1) Do not set both SW1-5 and SW1-6 ON at the same time. This may damage internal circuits.
(2) The power supply to the device supplying +5 V must be turned OFF before starting wiring work.
(3) Before connecting the RS-232C cable and turning on the power to an RS-232C device such as a
(4) When the Adapter is connected to an OMRON C200HX/HG/HE(-Z)E, CQM1H, or CS/CJ-series
PT (i.e., turning on the power to the Adapter), check that the cable is wired correctly and that the
DIP switch settings are correct. If the power is turned on while there is a wiring fault, the internal
circuits of the Adapter or the RS-232C device may be damaged.
