Function/description
Connects 24 VDC.
This connector can connect the following signals:
External RESET signal input (1 point)
User input readable via command (3 points)
User output operable via command (4 points)
Connects a PLC, PC, or the like to transmit commands to and
receives responses from the Reader/Writer.
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.
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.
Connects an antenna (the V720-HS03 or the like).
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.
