16.2 Connection Cable
16.2.2 RS-422 cable
2 Connector specifications
(1) GOT side connector
Use the following as the RS-422 interface and RS-422/485 communication unit connector on the
GOT.
For the GOT side of the RS-422 cable, use a connector and connector cover applicable to the GOT
connector.
(a) Connector type
9-pin D-sub (female)
(b) Connector model
3 Precautions when preparing a cable
Limit the length of the RS-422 cable to 1200m.
4 Connecting the terminating resistor
When connecting a PLC link module to a GOT, a terminating resistor must be connected to the PC link
module.
No terminating resistor needs to be connected on the GOT side as one is already built into the GOT.
The following describes how to connect it on the PC link module.
(1) F3LC11-2N
Set the terminator switch (TERMINATOR) on the front panel of F3LC11-2N to the "4-WIRE" side to
enable the terminator.
(2) LC02-0N
Connect the terminating resistor provided with the LC02-0N across SDA and SDB, and across
RDA and RDB on the terminal block.
