
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.
1.4.1 GOT connector specifications
(3) FUJI temperature controller side connector
Use the connector compatible with the FUJI
temperature controller side.
For details, refer to the user's manual of the FUJI
temperature controller.

Connecting terminating resistors
(1) GOT side
Set the terminating resistor setting switch of the GOT
main unit to "100 OHM".
For the procedure to set the terminating resistor, refer
to the following.
1.4.3 Terminating resistors of GOT
(2) FUJI temperature controller side
When connecting a FUJI temperature controller to the
GOT, a terminating resistor must be connected.
