Terminating Resistance Setting
For V7 Series:
•
The terminating resistance of the V7 series should be set on the DIP switch.
•
When the PLC and the master station are connected via RS-422/485, set the terminating
resistance at the PLC and the master station (CN1).
•
When the V7 series (master and slave stations) are connected via RS-485 (2-wire), set the
terminating resistance at the V7 series master station (MJ1/2) and the terminating slave station
(CN1).
