
Precautions when preparing a cable
(1) Cable length
The length of the RS-485 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) RKC temperature controller side connector
Use the connector compatible with the RKC
temperature controller side module.
For details, refer to user's manual of the RKC
temperature controller.

Connecting terminating resistors
(1) GOT side
When connecting a PLC to the GOT, a terminating
resistor must be connected to the GOT.
(a) For GT16, GT15, GT12
Set the terminating resistor by operating the
terminating resistor setting switch.
(b) For GT14, GT11
Set the terminating resistor by operating the
terminating resistor selector switch.
For the procedure to set the terminating resistor, refer
to the following.
