4.5 Cable Diagram at the time of replacement

The pin assignment and the shape of plug/socket connector of ST-3501T/C are the
same as those of GP-4501 series, but GP-3500 series are different.
Please note that there are precautions and restrictions as described below when
replacing GP-3500 series.
・ When a RS-422/485 device is connected via the COM1 port, if GP-3500 series is
replaced with GP-4500 series, it will be connected via the COM2 port of
GP-4500 series. (The cable diagram can be still used.)
Before GP-4500 series is connected, be sure to change the port setting to COM2 on
the Device/PLC setting. Also, please check the communication settings with
GP-Pro EX Device/PLC Connection Manual just in case.
