4 Introduction

4.1 The reader

The KTC RFID (Radio Frequency Identification) reader 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 “EU” and 902 to 928

MHz for the American market type “US”. 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.

4.2 RFID system

Figure 1 RFID Reader subsystem (up to 4 antennas possible)

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

the RF field with energy.

For testing and parameterizing the reader the Demo Software ReaderStart v2 can be used. The

communication between the ReaderStart v2 and the reader is based on a Dynamic Link Library (DLL) called

RRU4DotNet.dll, which may also be used for creating user specific lane controller applications. The DLL

includes all the relevant commands and functions, which are needed to control the reader. Additionally, the

reader may also be controlled by direct TCP communication.

The user-specific control software may also run on the reader directly. Thus, a stand-alone operation without

permanent network connection is possible

The KTC RFID reader is able to control antennas from the manufacturer Kathrein by using their proprietary

and thus in combination with the KTC RFID reader device there is no active support given by KTC when

using KRAI antennas.
