Interface Specifications

This section describes the specifications of each interface of the GP Series unit.

„Serial Interfaces

‹Serial Interface (COM1)

This interface is used to connect an RS232C/RS422/RS485 serial cable. A D-sub 9-pin plug connector is

used.

Communication method is switched via software

• For instructions on how to connect to other devices, always refer to the “GP-Pro EX

Device/PLC Connection Manual”.

• Always connect the #5 SG (Signal Ground) of the GP unit to the connected device,

especially if the connected device is also not isolated. Failure to do so may damage

the RS232C/RS422/RS485 circuit.

• When connecting an external device to the GP using the SG terminal, be sure to

check that no short-circuit loop is created when you setup the system.

When isolation is necessary, you can use either RS232C isolation unit (CA3-ISO232-01) on

COM1 or RS485 isolation unit (CA3-ISO485-01) on COM2.
