Precautions when preparing a cable

(1)Cable length

The length of the RS-232 cable must be 15m or less.

(2)GOT side connector

For the GOT side connector, refer to the following.

Precautions when preparing a cable

(1)Cable length

The length of the RS-422 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

Connecting terminating resistors

(1)GOT side

When connecting a PLC to the GOT, a terminating resistor must be connected to the GOT.

(a)For GT16, GT15, GT12

Set the terminating resistor setting switch of the GOT main unit to "Disable".

(b)For GT14, GT11, GT10

Set the terminating resistor selector to "330".

For the procedure to set the terminating resistor, refer to the following.
