Precautions when preparing a cable

(1)Cable

Use a shielded twisted pair cable of 0.3mm2 or more as a cable for GOT multi-drop connection.The following shows recommended model names and manufacturers of the cable to be used.

(3)GOT side connector

For the GOT side connector, refer to the following.

1.4.1 GOT connector specifications

Connecting terminating resistors

When connecting a Serial Multi-Drop Connection Unit to the GOT, a terminating resistor must be connected to the GOT.

(a)For GT16, GT15, GT12

Set the terminating resistor setting switch.

(b)For GT14, GT11, GT10

Set the terminating resistor selector switch.

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

1.4.3 Terminating resistors of GOT

(2)Cable for converting D-sub9 pin connector to terminal block

Create by yourself, referring to the following connection diagram.

Example of connection diagram for 2 pair wiring

Make sure to connect the wiring branched on the GOT side connector.

Use a shielded twisted pair cable of 0.2mm2 or more. Use an applicable cable to D-sub connector.

Wiring should be the shortest distance.
