■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) AZBIL control equipment side connector
Use the connector compatible with the AZBIL control equipment side module.
For details, refer to the user's manual of the AZBIL control equipment.
■3. Connecting terminating resistors
(1) GOT side
Set the terminating resistor by operating the terminating resistor setting switch.
For the procedure to set the terminating resistor, refer to the following.
➠
(2) AZBIL control equipment side
When connecting a AZBIL control equipment to the GOT, a terminating resistor must be connected.
