•
•
•
•
•
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 4).
In order to comply with FCC requirements for
RF exposure safety, a separation distance of
at least 23 cm (9.1 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.
A 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 disk drive
– Base-T-10/100 Ethernet® port
1.1.2 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(refer to Chapter 3).
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 time-
multiplexing strategy.
– Antenna power can be reduced by reconfiguring
the RF Transmit Power setting for the reader.

1.2.3 Setting the Reader RF Power
1.2 Authorized Antennas
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
the recommended power setting as calculated below.
The antenna authorized by the FCC for use with the
V740 Reader is described below.
IMPORTANT: No other antennas may be used with
the V740 Reader without violating FCC regulations. It
is the responsibility of the user to comply with this
requirement.
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 1.5 dB, the
maximum RF power that may be set is (36- 6 + 1.5) =
31.5 dBm.
