connections are explained.
Connecting method 1 (using MJ-D25)
• To connect the PLC and the V7 series at the MJ port, use the Hakko Electronics’ MJ to
D-sub conversion cable “MJ-D25” (0.3 m, metric thread) and the cable for 1 : 1
connection at CN1. For more information on the cable for 1 : 1 connection at CN1, refer

connection at CN1. For more information on the cable for 1 : 1 connection at CN1, refer
to “Wiring” in “Chapter 5 Connection to PLCs.”
• This combination of cables (MJ-D25 + 1 : 1 connection cable) can be used either for
RS-232C or RS-485 (RS-422) 2-wire connection.
• With RS-485 (2-wire connection), a maximum of 31 PLCs can be connected. For
information on connection between PLCs, refer to the instruction manual for the PLC.
Connecting method 2 (using V6-TMP)
• Use Hakko Electronics’ cable “V6-TMP” (3 m) when connecting the V7 series to a PLC
at the MJ port. The shielded frame ground of V6-TMP must be connected to the V7
series.
