Precautions when preparing a cable
(1) Cable length
The length of the RS-422 cable must be 1200m or less.
(2) GOT side connector
For the GOT side connector, refer to the following.
1.4.1 GOT connector specifications
(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
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.
