.
1:1 Connection Example Using RS-232C Port
Connection Example with E5CK Digital Controller
1:1 RS-485 Connection Example Using RS-422A/485 Port
Note 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
