Address number (ADDRESS)

Set the address number of the VJ Series itself. An address number of 1 to 99 may be
assigned in any order. However, there is a limitation - the number of VJ Series to be
connected to a single communication port is limited to 31.

Example of connecting four VJ Series signal conditioners to a higher-level device by setting
address numbers of 1, 50, 10, and 20

ADDRESS=1

ADDRESS=20

ADDRESS=10

ADDRESS=50

Maximum overall cable length of 1200 m
for a maximum of 31 substations

Communication rate (BAUD RATE)

Set the communication rate identical to that of the higher-level device to be connected.
(Otherwise, proper communication cannot be achieved.) The unit of the communication
rate is bps (bits per second).

Parity (PARITY)

Set the handling of parity to be carried out when data is sent or received. Set the parity bit
state identical to that of the higher-level device to be connected.

Stop bit (STOP BIT)

Set the stop bit identical to that of the higher-level device to be connected.

Data length (DATA LEN)

Set the data length identical to that of the higher-level device to be connected. (When
Ladder or MODBUS communication is chosen in protocol selection, the data length is
fixed.)
