side (CD485/V)

When combining the module, because the communication line is connected between the modules with each other, wire only the

communication terminal on the both end of the combination module.

Terminating resistor should be provided for a temperature controller which will be a terminal. When combining the module,

provide the terminating resistor to the end of the combination module (the one that is far from the converter). When using X-TIO,

turn ON the terminating resistor selector in the terminal base.

For the terminal number of the temperature controller, refer to the following table.

Precautions when preparing a cable

(1) Cable length

The length of the RS-485 cable must be 1200m or less.

(2) 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) RKC temperature controller side

The terminating resistor must be connected to the

RKC temperature controller.
