*1 The RI/5V can be switched. Use the IPC’s switch to change if necessary.
*2 Set up the SIO type with the DIP Switch. Please set up as follows according to SIO type to be used.

GP-Pro EX Device/PLC Connection Manual 5

 A Series CPU Direct Driver

*3 When making communication between an External Device and COM port on the Expansion slot,
only RS-232C is supported. However, ER (DTR/CTS) control cannot be executed because of the
specification of COM port.
For connection with External Device, use user-created cables and disable Pin Nos. 1, 4, 6 and 9.
Please refer to the IPC manual for details of pin layout.
*4 Set up the SIO type with the BIOS. Please refer to the IPC manual for details of BIOS.
*5 When setting up communication between an External Device and the RS-232C/422/485 interface
module, use the IPC (RS-232C) or PS5000 (RS-422/485) cable diagrams. However, when using
PFXZPBMPR42P2 in a RS-422/485 (4-wire) configuration with no flow control, connect 7.RTS+
and 8.CTS+, and connect 6.RTS- and 9.CTS-.
When using RS-422/485 communication with External Devices, you may need to reduce the
transmission speed and increase the TX Wait time.
*6 To use RS-422/485 communication on the RS-232C/422/485 interface module, the DIP Switch
setting is required. Please refer to "Knowledge Base" (FAQs) on the support site. (http://www.pro-
face.com/trans/en/manual/1001.html)

*7 Set up the SIO type with the DIP Switch. Please refer to the IPC manual for details of DIP Switch.
The BOX Atom has not a switch to set the RS-232C, RS-422/485 mode. Use the BIOS for the
setting.
*8 For the connection with the External Device, on the user-created cable read as if the connector on
the Display-side is a M12 A-coding 8 pin socket. The pin assignment is the same as described in
the cable diagram. For the M12 A-coding connector, use PFXZPSCNM122.
*9 In addition to COM1, you can also use the COM port on the optional interface.
*10 Install the optional interface in the expansion slot.

• We recommend that ferrite core should be attached to your cable for improving noise
tolerance.
• Attach ferrite core to the closest position to the connector on both ends of the cable.
Also, wind the cable around ferrite core (1 turn) to expect more noise tolerance as
shown below.
