RS-422/RS-485 connection

Prepare a communication cable on your side. Twisted pairs of 0.3 mm sq. or above are recommended.

The maximum length of wiring is 500 m.
* The maximum length varies depending on the connected device. Check the specifications for each device.
 Connect twisted pairs bSD and  SD, and bRD and  RD.
 If the PLC has a signal ground (SG) terminal, connect it.

To use a terminal block for connection, use Hakko Electronics’ optionally available “TC-D9”.

The DIP switch on the back of the V9 unit is used to set the terminating resistance.
For more information on DIP switches, refer to “1.2.6 DIP Switch (DIPSW) Settings” (page 1-7).
 Connect a shielded cable to either the V9 series or the connected device. The connection diagram shows the case where
the shielded cable is connected on the V9 series side. Connect the cable to the FG terminal on the backside of
MONITOUCH.
- RS-422 (4-wire system)
- RS-485 (2-wire system)

If noise disturbs communications, connect a shielded cable to both the V9 series and the connected device.
- RS-422 (4-wire system)
