2. Introduction

2.2. RFID system

An RFID system consists of the control computer of the actual reader, antennas, antenna connection cables and the

tags. The gure below shows the schematic structure of the system:

The tags consist of an antenna and a small chip. The chip is the true carriers of the information,

the EPC number. This number can be identied products or product groups. Alternatively, the EPC can be overwritten

with new information.

To read the tag information, the reader sends an RF carrier by an active antenna and thus supplies the tags in the RF

eld with energy.

If the information in one tag should be read, this tag should be rst selected (inventoried) from the population of tags.

Upon successful completion of the inventory, the EPC number of each tag can be read and sent to the PC. Additional

information can be attached to the EPC, for example the antenna which read it the time point at which it was read.

2.1. The reader

The Kathrein RFID (Radio Frequency Identication) reader RRU4 is a multi-protocol-capable device for reading active

and passive RFID tags in the frequency range from 865 to 868 MHz for Europe type “E6” and 902 to 928 MHz for the

American market type “U6”. As supplied the unit can read and write tags in accordance with the EPC-Gen2 standard.

Additional protocols can be loaded using software updates.

The device has a maximum of four external antenna ports for connection of the transmission/reception antennas for

communication with RFID tags.

For integration into a variety of infrastructures, the device has different communication interfaces depending on the

variant. The power supply is provided by a 4-pin M12 panel connector in A coding.

Important!

The reader operates using the frequency hopping process, so as to avoid faults and interference between readers.

Within the FCC area this procedure is mandatory. The readers changes its transmission frequency randomly,

with equal distribution across the 52 available channels. Each channel is used for max. 400ms in an interval of 20s.

For testing and parameterizing the reader the Demo Software“Reader Start v2”can be used.

The communication between the“Reader Start v2” and the reader is based on the DLL, which includes the commu-

nication protocol ((A)). For specic applications the user can build its own control software based on the reader DLL.

The DLL includes all the relevant commands and functions, which are needed to control the reader
