Name Function/description
1 Power connector Connects 24 VDC.
2 Input/Output connector
This connector can connect the following signals:
z External RESET signal input (1 point)
z User input readable via command (3 points)
z User output operable via command (4 points)
* For the application of specialized antennas, some outputs are reserved for
exclusive use. For the connection in such cases, refer to the respective
Antenna Manual.
Host communication connector
Connects a PLC, PC, or the like to transmit commands to and receives
responses from the Reader/Writer.
COM1
This is a host port used for ordinary communication. The interface conforms to
RS-232C and RS-485, either of which is used selectively as appropriate.
3
COM2
This port conforms to RS-232C and is solely used for setup. The RS-232C
interface of this port operates independent of the RS-232C interface of COM1.
The RS-485 pin is provided for extension when multi-dropped connection is
used.
4
Transmitting/receiving
antenna connector (TX/RX
ANT)
Connects an antenna (the V720-HS04 or the like).
5
Receiving antenna connector
(RX ANT)
A receive-only antennal can be connected to this connector. This connector is
provided for special applications, e.g., connection with a gate antenna. Leave
this connector unconnected in normal use.
Indicators The indicators shows the state of operation, as shown below:
RUN Green Turns on when the Reader/Writer is operating normally.
COMM Green Turns on when the Reader/Writer is in communications with the Tag.
NORM Green Turns on when communication has completed normally.
ERROR Red
zTurns on when a communication error has occurred.
zTurns on when a system error has occurred.
IN1 - IN3 Green Turns on when the input signal is on.
6
OUT1 - OUT4 Green Turns on when the output signal is on.
Note
● Do not connect antennas other than those recommended by OMRON.
● When connecting a Receive-only Antenna, enable the Receive-only Antenna Mode with the Antenna Changeover
Command (AC).
