(2) Precautions when preparing a cable
(a) Cable length
The length of the RS-422 cable must be 500m or
less
(b) GOT side connector
For the GOT side connector, refer to the following.
1.4.1 GOT connector specifications
(c) KEYENCE PLC side connector
Use the connector compatible with the KEYENCE
PLC side module.
For details, refer to the KEYENCE PLC user's
manual.
(3) Connecting terminating resistors
(a) GOT side
When connecting a KEYENCE PLC to the GOT, a
terminating resistor must be connected to the GOT.
• For GT16, GT15, GT12
Set the terminating resistor setting switch of the
GOT main unit to "Disable".
• For GT14, GT11, GT10
Set the terminating resistor selector to "330 ".
For the procedure to set the terminating resistor,
refer to the following.
