*1 Connect FG grounding to the appropriate part of a cable shield line.
*2 Terminating resistor should be provided for a PLC which will be a terminal.

Precautions when preparing a cable
(1) Cable length
The total distance (between GOT and controllers) of
RS-422 cable must be 13m or less.
(2) Connector conversion box side connector
For the Connector conversion box side connector, refer
to the following.
6.7 Connector Conversion Box
(3) GE PLC side connector
Use the connector compatible with the GE PLC side
module.
For details, refer to the GE PLC user's manual.

Connecting terminating resistors
(1) GOT side
When connecting a PLC to the GOT, a terminating
resistor must be connected to the GOT.
Set the terminating resistor setting switch of the GOT
main unit to "Disable".
For the procedure to set the terminating resistor, refer
to the following.
4.2 Back Panel
(2) GE PLC side
When connecting a GE PLC to the GOT, a terminating
resistor must be connected.
