Precautions when preparing a cable
(1) Cable length
(a) The length of the RS-485 cable used for
connecting the temperature 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
connecting the temperature controller to the GOT
The total distance (between GOT and controllers)
of RS-485 cable must be 13m or less.
(2) Connector conversion box side connector
For the connector conversion box side connector, refer
to the following.
6.6 Connector Conversion Box
(3) External cable side connector
For the connector specifications of the external cable
side, refer to the following.
8.2 External Cable, Relay Cable
(4) YOKOGAWA temperature controller side connector
Use the connector compatible with the YOKOGAWA
temperature controller side.
For details, refer to the user's manual of the
YOKOGAWA temperature controller.
