2.1 Application
2.1.1 Description
The ASR700 is a stationary reader, which is used for contact less identification in combination
with passive transponders. The hardware of the ASR700 reader is designed for noisy environ-
ments. With the on board signal processor it is possible to read transponders where other read-
ers could not detect them (for example in slaughterhouses).
It has been developed for stationary use. Combined with one of our antennas it provides a flexi-
ble and universal RFID system.
Antennas with various dimensions and read ranges are available to closely match individual re-
quirements.
The ASR700 reader is compatible with the ISO 11784/5 standard and can read HDX- or FDX-B
compatible transponders. The transponders are registered within an extremely short time and
over a wide detection area. Individual parameters of the read function can be configured.
It can be run using a computer, but application software is then required to drive the reader and
to further process the transponder data supplied.
The message format of the transmitted transponder data is configurable. For description of the
data protocol see chapter 5.

2.1.2 Contact less identification with RFID
How RF identification works.
The items to be identified are fitted with passive transponders, which contain the identification
data. A reader is required for communication with the transponders. The reader generates a
high frequency field using an antenna. This high frequency field activates each transponder,
which is inside the reading range. The high frequency field is used for supplying the trans-
ponder with energy and for transmitting the transponder data to the reader. From the received
data, the reader generates a data block (ID message). This ID message is sent out by an inter-
face to a controller for further processing.
The reading range depends on the antenna and the environment.
The following things may influence the reading range (see also chapter 8):

The following things may influence the reading range (see also chapter 8):
• Mounting antenna on or near metal
• Noisy environment (for example electrical machines, screens etc.)
• Antenna mistuned (see chapter 2.2.4 auto tuning for details)
• Noisy environment (for example electrical machines, screens etc.)
• Antenna mistuned (see chapter 2.2.4 auto tuning for details)
The demonstration software Asrdemo.exe includes tools for checking the tuning state of the an-
tenna and the noise of the environment.
