General:

As this technology is based on radio frequency, one must exercise the following operational and
mounting instructions to achieve best operation:

• Metal affects radio signals. Normally the antenna has to be as far away as possible from any
metal object and it’s damping influence on the magnetic field. Only this leads to the best
distribution of the magnetic field in the reading range. Very important as well is not to have “short
circuits”, in the vicinity of the antenna, damping the magnetic field. A “short circuit” is any metal
near the antenna, building a “metallic ring”, so that currents introduced by the RF-field can flow,
destroying the energy needed for the tag to operate.

• Care must be exercised to reduce or eliminate unwanted signals (so called interference or
noise) from external sources. The reading range may be reduced by following noise sources:

• portable two way radio

• cellular phones

• switching power supplies

• computer monitors

• frequency converters (e.g. motor control systems)

• The read range is depending upon

• performance of the reader

• size of the antenna

• size of the tag (the bigger the better)

• orientation of the tag antenna plane to the reader antenna plane

• quality of the tag

• matching of reader antenna size and tag (-antenna) size

• environmental, electrical noise

• If influence of metal can not be fully avoided a tuning of the antenna is required and will

improve reading range

2 System Description

Manual and Specification

SIR-2720 (13.56 MHz Midrange Reader)

The "SIR-2720 13.56 MHz Midrange Reader System" is hereafter referred to as "Reader."

This manual describes the SIR-2720 13.56 MHz Midrange Reader System, Reader for short.

This SIR-2720 Midrange Reader System is designed as a multi-tag system to read and write information
stored on transponders (tags). The operating frequency of 13.56 MHz yields a relatively wide reading
range of up to 700 mm depending on antenna system (mainly with larger externally attached antennas)
and transponder -type and -size. This first generation of SIR-27xx Midrange Readers is based on the
hardware developed by scemtec Transponder Technology featuring an RF transmitting power of
max. 1.4W @ 50Ω-load. The SIR-2720 13.56 MHz Midrange Reader System is the second product in
the SIR-27xx product family. The transmission of data between the reader and a host computer via the
asynchronous RS232 interface can be up to 115200 baud. A USB 2.0 full speed compatible interface
and an Ethernet port is available as well.

The reader is compatible with standards ISO/IEC 15693- 2 and ISO18000-3 "A."
