The OMRON V740 RFID Reader/Writer (herein
after denoted as Reader) uses RFID (radio
frequency identification) technology to read data
stored on RFID tags. The Reader operates
analogous to an SQL (structured query language)
server, providing tag data in response to requests
from another application. A separate software
application may be used to direct its operation and
provide a user interface.
The Reader supports UHF (ultra high frequency)
antennas, which are available separately. The
Reader supports multiple configurations of UHF
antenna ports and transfers data to a remote
computer over a network connection.

This installation and usage guide explains how to
install the V740 Reader, how to use the browserbased interface, and how to control the Reader
remotely. .
Use the instructions provided with the antennas to
install and service the antennas.
Note: Because customer requirements dictate the
placement of Reader and antenna components,
your OMRON representative will supply this
information separately.
Before You Begin
Installation Requirements
•The Reader is shipped with a certified limited
power source with a cable length of 1.8m (6ft).
•Use only authorized antennas and cables to
maintain FCC approval (see page 3).
Performance Considerations
Reader performance may be affected by external
factors including tag variables and environment.
Performance tests conducted under typical
operating conditions at your site are recommended
to help you optimize system performance.
Tag Variables
There are several variables associated with tags
that can affect Reader performance:
•Application surface — Some materials interfere
with tag performance including metal and
moisture. Tags applied to items made from or
containing these materials may not perform as
expected.
•Tag orientation — Reader performance is
affected by the orientation of the tag in the
antenna field.
•Tag model — many tag models are available.
Each model has its own performance
characteristics.
•In order to comply with FCC requirements for
RF exposure safety, a separation distance of
at least 21 cm (8.3 in) needs to be maintained
between the radiating elements of the antenna
and the bodies of nearby persons.
• Provide strain relief for all Reader connections.
• The minimum screw size for mounting the
Reader is #12 (M5). Use suitable wall anchors
when mounting to drywall or masonry.
•An Shielded Ethernet cable must be used to
communicate with other devices.
•Multiple Readers and antennas can be used in
combination to enhance detection at specific
locations provided the software application is
able to synchronize antenna operation.
•Recommended minimum configuration for a
computer running an application that interfaces
with the V740 Reader:
Pentium® 400 MHz processor
–
– 128MB memory
– 10 GB hard drive
– Microsoft® Windows® 2000 or Windows XP
operating system
– Base-T-10/100 Ethernet® port
– CD-ROM drive
Environment
Reader performance may be affected by the
following:
•Metal surfaces such as desks, filing cabinets,
bookshelves, and wastebaskets may enhance
or degrade Reader performance.
Mount antennas as far as possible from metal
surfaces that are adversely affecting system
performance.
•Devices that operate at 900 MHz, such as
cordless phones and wireless LANs, can
interfere with Reader performance.
These devices may degrade performance of
the Reader. The Reader may also adversely
affect performance of 900 MHz devices.
•Antennas operating in close proximity may
interfere with one another, thus degrading
Reader performance.
•Interference from other antennas may be
eliminated or reduced by using either one or
both of the following strategies:
Affected antennas may be synchronized by a
–
separate user application using a timemultiplexing strategy.
The only antennas authorized by the FCC for use
with the V740 Reader/Writer are listed below.
Detailed information on each antenna is available
from their respective manufacturers.
IMPORTANT: No other antennas may be used
with the V740 Reader/Writer without violating FCC
regulations. It is the responsibility of the user to
comply with this requirement.
The only cables authorized by the FCC for use with
the V740 Reader/Writerare listed below:
Setting the Reader RF Power
During initial installation, the Reader must be
properly configured to use the correct RF power to
comply with FCC regulations. DO NOT increase
the power beyond this level.
The maximum RF power is determined from
antenna gain and antenna cable loss using the
formula:
Pmax = 36 dBm - Antenna Gain + Cable Loss
For example, if the antenna has a maximum gain
of 6 dBi, and the cable has a minimum loss of 1.4
dB, the maximum RF power that may be set is (366 + 1.4) = 31.4 dBm.
The Reader RF Power is set through the Settings Page as described on Page 10. Note that in no
case may the power be set higher than 32.5 dBm.
