(2) Precautions when preparing a cable
(a) Cable length
The length of the RS-422 cable must be 1200m or less.
(b) GOT side connector
For the GOT side connector, refer to the following.
➠ 1.4.1 GOT connector specifications
(c) YOKOGAWA PLC side connector
Use the connector compatible with the YOKOGAWA PLC side module.
For details, refer to the YOKOGAWA PLC user's manual.
(3) Connecting terminating resistors
(a) GOT side
1) For GT27,GT25(Except GT2505-V?,GT23
Set the terminating resistor setting switch of the GOT main unit to "Disable".
2) For GT2505-V
Set the terminating resistor selector to "330Ω".
For the procedure to set the terminating resistor, refer to the following.
➠
1.4.3 Terminating resistors of GOT
(b) YOKOGAWA PLC side
When connecting a PLC link module to a GOT, a terminating resistor must be connected to the PC link module.
The following describes how to connect it on the PC link module.
• F3LC11-2N
Set the terminator switch (TERMINATOR) on the front panel of F3LC11-2N to the "4-WIRE" side to enable the
terminator.
• LC02-0N
Connect the terminating resistor provided with the LC02-0N across SDA and SDB, and across RDA and RDB
on the terminal block.
