*1 R is the terminating resistor. Connect the terminating resistor (110W) between terminals SDA
and SDB.
*2 Connect the shield of the FX2N-485-BD, FX1N-485-BD using shielded twist-pair cable to
ground (100W or less).
Please adjust the grounding only to one side.
*3 Connect terminal FG to each terminal of the programmable controller body, grounded with
resistance of 100W or less. However, for the computer link unit of the A series programmable
controller, see the manual of the computer link unit.
*4 If an RS485/232 adapter is required, please use the FX-485-PC-IF. When using the FX-
485PC-IF with this wiring method, either take account for or ignore the “echo” of the commands
sent by the computer

Two-pair Wiring
*1 R is the terminating resistor. Connect the terminating resistor (330W) between terminals SDA
and SDB, and terminals RDA and RDB.
*2 Connect the shield of FX2N-485-BD, FX1N-485-BD using shielded twist-pair cable to ground
(100W or less).
Please adjust the grounding only to one side.
*3 Connect terminal FG to each terminal of the programmable controller main body grounded
with resistance of 100W or less. However, as for the computer link unit of the
A series programmable controller, see the manual of the computer link unit.
*4 When using RS232/485 or RS232/422 adapter, please the adapter use FX-485PC-IF.
