Serial Interfaces
This interface is used to connect an RS-232C/RS-422/RS-485
*1
cable. Connect to the D-SUB 9-pin plug type
connector.
For host controller (PLC, etc.) connection information, refer to the “GP-Pro EX Device/PLC Connection
Manual”.
In the case of RS-232C
In the case of RS-422/RS-485
*1
Communication method is switched via software.
*2
The RI/VCC selection is switched via software. The VCC output is not protected against over current.
To prevent damage or a unit malfunction, use only the rated current.
*3
Select AWG22 cable to use out of two green cables.

• The GP3000H Direct-connect cable’s serial interface is not isolated. When the
host (PLC) unit is also not isolated, and to reduce the risk of damaging the RS-
232C/ RS-422/RS-485 circuit, be sure to connect the SG (Signal Ground)
terminal.
