■2. 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.
(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.
■3. Connecting terminating resistors
(1) GOT side
Set the terminating resistor by operating the terminating resistor setting switch.
For the procedure to set the terminating resistor, refer to the following.
