AWID PROPRIETARY
transponder. Once the IC is energized, it goes through an initialization process and is ready to
accept further commands. Upon receiving a command to broadcast its identity, the RFID ASIC
begins to broadcast its identity through a low energy back-scattering technology that selectively
reflects or backscatters the electromagnetic energy back to the reader. The receiving circuits in
the reader senses and decodes this back-scattered signal and hence determines the identity of
the transponder.

3.1 Measuring Read Distance
The transponder for this Reader is designed for windshield mounting. To measure the read
range between the Reader and the transponder, the transponder must be placed behind a piece
of glass of about 0.25 inches in thickness and the transponder must be flat against the glass.
Grasp the transponder by the edges and hold the transponder in the same orientation as
indicated in the transponder. Move the transponder toward the Reader, with the card surface
parallel to the Reader, until confirmed data detection occurs. This indicates that the Reader has
successfully read the transponder. In order to read again, the card must be fully withdrawn from
the Reader’s field of view and then approached again.
NOTE: FAILURE TO FOLLOW THE INSTALLATION GUIDE MAY RESULT IN POOR
PERFORMANCE OR EVEN CAUSE PERMANENT DAMAGE TO THE READER,
THUS VOIDS THE PRODUCT WARRANTY.
4.0 PREPARATION FOR INSTALLATION
4.1 Site Survey:
Always conduct a site survey before starting installation, avoid any possible sources of
interference. If the Reader is not installed properly, the performance will be degraded or more
seriously the Reader may be damaged. The following is a list of installation procedures that
should be followed during installation:
