This document will describe the components of the reader system ARE K1 / PFB and the procedure
how to do the set up of the reader. The main features of the reader are listed below:
• algorithms to read Trovan und PSK1-transponders
• the Profibus-DP-interface is opto-isolated and placed inside of the housing, allowed baud rate are
up to 12MBit/s
• the node address of the reader can be chosen from 2 to 99, using adress switches which can be set
without opening the housing
• the allowed supply voltage is 18 to 28VDC (typical 24V)
• The reader is equipped with an galvanic disconnected digital input. The positive edge causes a
trigger signal. The input voltage is 24 V.
• low power consumption of reader < 24Watt
• high reliability for reading within an industrial environment.
• reading distance using the ID 200 transponder and the AAN FK2 antenna:
- 40 cm in static application
- 30 cm when transponder is moved with up to 10m/min
• different antenna types available to meet special application demands
• fully compatible with Compact reader system ARE I2 / PFB
• the cabling concept of the reader is optimised to service demands.
• the protection class of the housing is IP65
• ambient temperatur limit: -20 to 70 °C
2 System Overview
The reading systems consists of two modules (see Figure 2-1)
• the reader box ARE K1/PFB and
• the active antenna (i.e. AAN FK2)
By means of the active 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.

Figure 2-1: Concept of the Reading System
The reader is fully controlled by an Profibus-Master while using the integrated Profibus interface.
The antenna must not be brought next to a metal surface. This could lead to a significant change of
the properties of the antenna circuit, which in turn reduces the reading range considerably. Please
take account to the installation manual of the antenna!
Environmental electromagnetic noise may also reduce the specified reading performance.
Special hints to overcome these problems are documented in chapter 3 and in the installation manuals
of the antenna.
The antenna is connected to the reader by the antenna cable. The typical length of the cable is 5 m.
3 Project Planning
For proper function of the identification system attention should be paid to the mounting of antenna
and antenna cable according to the rules, pointed out in the installation manuals of the antenna and
the reader.
Make shure that the reader box is grounded. Otherwise the reading distance can be reduced significantly and the electronics can be damaged by electrostatic discharge.
To get reliable readings, the distance between reader and transponder must be within the specified
reading volume.
The reading characteristic in front of the antenna is not isotropic. To get the maximum reading distance, the orientation between antenna and transponder must be well suited. The best orientation depends on the type of antenna. Please take attention to the installation manual of the antenna.
To get reliable reading performance, the time of the transponder while crossing the sensitive area of
the antenna must be co-ordinated to the data transfer characteristics of the transponder. In general
the time depends on the speed of the transponder, the size of the transponder and the way the transponder is mounted on the vehicle and must be verified by field tests.
Environmental electromagnetic noise may also reduce the read range considerably.
Arrangement to eliminate such troubles must be done specific to the application by the help of engineers of the manufacturer.
