■2. Precautions when preparing a cable
(1) Cable length
The length of the RS-485 cable must be 500m or less.
(2) GOT side connector
For the GOT side connector, refer to the following.
➠
(3) OMRON temperature controller side connector
Use the connector compatible with the OMRON temperature controller.
For details, refer to the user's manual of the OMRON temperature controller.
■3. Setting terminating resistors
(1) GOT side
Set the terminating resistor setting switch of the GOT main unit to "100 OHM".
For details of terminating resistor settings, refer to the following.
➠
(2) OMRON temperature controller side
When connecting a OMRON temperature controller to the GOT, the terminating resistor must be connected to the
OMRON temperature controller.
