(2) The contents of the CompoWay/F command enclosed in the FINS mes-
sage that is sent is as follows:
Node number + subaddress + SID + command text (ASCII must be used.)
STX, ETX+BCC are not required when sending FINS. They are added
automatically for serial communications.
Connection diagrams are provided here. OMRON recommends the use of
shielded twisted-pair cables for actual wiring to enhance noise resistance. For
details on wiring methods, refer to 3-4 RS-232C and RS-422A/485 Wiring .

Be sure to connect terminating resistance of between 100 and 125 Ω (1/2 W)
to the terminals of the remote devices at either end of the RS-422A/485 trans-
mission path. (Set the terminating resistance on the Board/Unit by turning
ON/OFF the Terminating Resistance Switch.)
