
Precautions when preparing a cable
(1) Cable
Use a shielded twisted pair cable of 0.3mm
2
or more as
a cable for GOT multi-drop connection.The following
shows recommended model names and manufacturers
of the cable to be used.
(2) Cable for converting D-sub9 pin connector to
terminal block
Create by yourself, referring to the following connection
diagram.
Make sure to connect the wiring branched on the GOT side
connector.
Use a shielded twisted pair cable of 0.2mm
2
or more.
Use an applicable cable to D-sub connector.
Wiring should be the shortest distance.
(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 of the
GOT main unit to "Disable".
(b) For GT14, GT11, GT10
Set the terminating resistor selector switch.
For the procedure to set the terminating resistor, refer
to the following.
