Read Range
The PosiXtend extended range proximity reader is designed to offer the best possible
read range for all installations. The PosiXtend reader automatically calibrates its read
range to the maximum possible range, however in certain installations the read range
may be reduced due to the environment. It is strongly recommended that you test the
PosiXtend reader before mounting and installing the reader.
Testing the Read Range
Test the reader's range for your particular installation site before mounting and
installing the unit.
Perform the read range test as close as possible to the final mounting
location.
1. Connect the PosiXtend extended range proximity reader to a power supply
unit and power up the reader.
2. Position an access card or key tag parallel to the reader, and move the card
or key tag toward the reader slowly until the reader beeps to indicate that the
card or key tag has been read.
3. Measure the read range distance and compare it to the values in the "Technical
Specifications" on page 3. If the read range is drastically reduced, Ferrite plates
can be used to decrease the interference and thus increase the range.
Automatic Read-Range Calibration
On power up, the PosiXtend reader will automatically calibrate its read range to
the maximum possible range for the installation site. The reader will beep during
the calibration sequence, which lasts approximately 15 seconds. When the
automatic read-range calibration is complete, the reader will emit a long beep
("Beeeeeeeep"). After the initial read range calibration is complete, the PosiXtend
reader will continue to fine-tune its read range during normal operation.
Please note that after powering up the unit, the automatic range
adjustment feature can take up to 5 minutes before it stabilizes the
reader's maximum range.
Range Reduction
If the PosiXtend extended range proximity reader is mounted in an electrically
noisy environment, on a metallic surface, or within close range of a CRT or a
computer monitor, the read range will be reduced. This range reduction can be in
excess of 35% depending on the type of interference. Refer to "Mounting on
Metal" on page 6 for more information.
