Connection Method 1

Connecting the MJ1/MJ2 of the master to CN1 connectors of the slaves

Communication between V9 units: RS-485 (2-wire system), maximum length = 500 m
PLC
(a) Connection between master and PLC
Select the port for connection from among CN1, MJ1 and MJ2.
The communication settings and connection method are the same as those for 1 : 1 connection.
(b), (c) Connection between master and slave
Choose the connecting port of the master between MJ1 and MJ2.
The connecting port of the slave should be CN1. It is convenient to install the optional terminal converter "TC-D9".
Use the "V6-MLT" cable (3 m). If the distance is greater than 3 meters the customer should prepare a terminal block and
extension cable (c), and should make the connection through that terminal block.
(d), (e) Connection between slaves
Use the RS-485 (2-wire system) connection. It is convenient to install the optional terminal converter "TC-D9". Use
twisted-pair cables of 0.3 mm sq or greater.
(b), (c), (d), (e) The maximum length of the wiring among the master and slave is 500 m.

* As a measure against noise, connect the frame ground terminal of each V9 series at one side only. The frame ground of V6-MLT
must be connected to the V9 series.
 When no TC-D9 is used:
Install jumpers between +SD and +RD as well as SD and RD.
