Make sure to pull the cable shield line into inside the connector cover, and treat the line end for obtaining shield effect.
(1) Precautions when preparing a cable
(a) Cable length
The maximum distance (between GOT and
controllers) of RS-485 cable must be 13m or less.
(b) Connector conversion box side connector
For the Connector conversion box side connector,
refer to the following.

(c) FUJI PLC side connector
Use the connector compatible with the FUJI PLC
side module.
For details, refer to the user's FUJI PLC manual.
(2) Connecting terminating resistors
(a) GOT side
When connecting a PLC to the GOT, a terminating
resistor must be connected to the GOT.
Set the terminating resistor setting switch of the
GOT main unit to "Enable".
For the procedure to set the terminating resistor,
refer to the following.
