■2. Precautions when preparing a cable
(1) Cable length
(a)
The length of the RS-485 cable used for direct connecting the indicating controller to the
communication converter
The length of the RS-485 cable must be 1200m or less.
(b)
The length of the RS-485 cable used for direct connecting the indicating controller to GOT
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) Shinko Technos indicating controller side connector
Use the connector compatible with the Shinko Technos indicating controller side.
For details, refer to the user's manual of the Shinko Technos indicating controller.
■3. Connecting terminating resistors
(1) GOT side
(a)
For GT27, GT25(Except GT2505-V), GT23
Set the terminating resistor setting switch of the GOT main unit to "Enable".
(b)
For GT2505-V
Set the terminating resistor selector to "110Ω".
For the procedure to set the terminating resistor, refer to the following.
➠
(2) Shinko Technos indicating controller side
When connecting a Shinko Technos indicating controller to the GOT, a terminating resistor must be connected to the
Shinko Technos indicating controller.
