RS-422/485 Connection
•
Connect twisted pairs bSD/
−
SD and +RD/
−
RD.
•
If the PLC has the terminal for signal ground (SG), be sure to connect a wire.
•
Connect the shielded cable either to the V7 series or PLC side. This connection diagram shows
the case where the shielded cable is connected on the V7 series side.
When connecting the shielded cable to the V7 series side, connect it to pin 1 of the connector or
the connector case cover.
The metal shell of the modular jack 2 on the V706 is used as SG (signal ground). Connect the
shielded cable to the metal shell of modular jack 2.
•
To use a terminal block for connection, use Hakko Electronics’ “TC485” optionally available. When
using TC485 on the V706, the option unit DU-01 must be installed.
•
The DIP switch on the side or back of V7 series units is used to set the terminating resistors. For
more information, refer to the description of the DIP switch setting in the relevant Hardware
Specifications.
•
Twisted pairs of 0.3 mm sq. or above are recommended.
