Attachment Method
• For the GP-4200 series, attach the unit to the panel.
Attaching the Unit directly to the Display
When attaching the unit on the rear side of the Display, among the 4 screws shown in the diagram
below, use 2 horizontally positioned or 2 vertically positioned screws to attach the unit. If the
Display already has an attachment, it may restrict the direction in which you can place the unit.

1) Attach one screw to the Display's rear side.
Use a torque of 0.5 N•m to 0.6 N•m (4.4 lb-in
to 5.3 lb-in).
2) Attach the unit to the Display.
3) Slide the unit in the direction of the arrow
so the unit is hooked by the screw from step1.
4) Fix the unit in place with another screw.
Use a torque of 0.5 N•m to 0.6 N•m (4.4 lb-in
to 5.3 lb-in).
• When attaching the unit to the Display, be
careful with the attachment position.
• Attach the unit to a stable surface. Do not
leave the unit hanging by its cord.
• Be careful with wire placement.
Overlapping cords may cause noise.
• When attaching another unit to the
Display, be careful of the place for the
attachment.
• If this unit and Pro-face Product, VM Unit
(GP2000-VM41) are attached to AGP-
35*0T at the same time, only when this
unit is attached in the position as shown
below, it's possible to attach the VM Unit
with it at the same time.
• Make sure the unit is placed inside the
edges of the Display.

Display side settings
When connecting the RS-232C isolation unit,
the following two settings are made in the
Display's Offline mode or using the screen
creation software.
• Setting the Display's communication
method to RS-232C
• Setting the Serial Interface port's number
9 pin to VCC
In the case of the operation in the Offline
mode, change it with [Peripheral Settings] of
[Device PLC/Settings]. For the software's
operation, refer to “Device/PLC Connection
Manual”.
CE Marking
• The CA3-ISO232-01 and CA3-ISO485-
01 are a CE marked, EMC compliant
