Introduction
This document describes technical features and directions for installation of the Long Range Reader with external
antennas due to read the following types of transponders, some defined in ISO 11784 /11785:
FDX-B
HDX
Destron
Datamars
Trovan
PSK with an side band carrier of fc/2 and 16 field cycles per bit
furthermore Read-Only transponder using ASK 64bit Manchester encoding with an data transfer
rate of 2 kBaud( e.g. EM 4102)
By means of the external antenna the reader generates an alternating magnetic field, which powers the transponder.
Coded signals sent back from the transponder are received and decoded by the reader. The result is fed via the RS
232 interface to the next level of the evaluating system
The comands to control the operation of reader uses parts of the ASB 1.0.

Installation of the Reader
2.1
Using Serval Readers within a Close Operating Area
A synchronisation of the readers is not available.
Therefore the operation of serveral readers within an close area may reduce the reading performance of the readers
significantely. The reduction of the reading performance must be tested.
2.2
Reading Performace
The reading range and the reading area depends on size of the applied antenna. The decoder will only work with a
Passive Two Coil Antenna AAN PT for example
Typ: AAN PT8 flex. 2m
