*1 Terminating resistors should not be provided for a PLC and
an RS-232/RS-422 interface converter which will be
terminals.
*2 Set the terminating resistor of GOT side which will be a


Precautions when preparing a cable
(1) Cable length
The maximum length of the RS-422 cable must be
500m or less.
(2) GOT side connector
For the GOT side connector, refer to the following.
1.4.1 GOT connector specifications
(3) JTEKT PLC side connector
Use the connector compatible with the JTEKT PLC side
module.
For details, refer to the JTEKT PLC user's manual.

Connecting terminating resistors
(1) GOT side
When connecting a JTEKT PLC to the GOT, a
terminating resistor must be connected to the GOT.
(a) For GT16, GT15, GT12
Set the terminating resistor setting switch of the
GOT main unit to "Disable".
(b) For GT14, GT11
Set the terminating resistor selector to "330 ".
For the procedure to set the terminating resistor, refer
to the following.
