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
(3) LS INDUSTRIAL SYSTEMS PLC side connector
Use the connector compatible with the LS
INDUSTRIAL SYSTEMS PLC side module.
For details, refer to the user's manual of the LS
INDUSTRIAL SYSTEMS PLC.
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.
1.4.3 Terminating resistors of GOT
(2) LS INDUSTRIAL SYSTEMS PLC side
When connecting an LS INDUSTRIAL SYSTEMS PLC
to the GOT, a terminating resistor must be connected.
