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.
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.

2.3. Kathrein RFID Antenna Interface © KRAI
By using Kathrein © KRAI antennas, reading rates can be increased by 33% compared to simple circular
The Kathrein-RFID Antenna Interface © KRAI consists of a digital control bus, which enables connection
between the RFID reader and the RFID antennas in order to allow control and regulation tasks in remote
The phase control elements integrated in the © KRAI antennas enable static or dynamic adjustment of
antenna characteristics.
Due to this, four different polarizations can be selected for the new 70° Wide Range antenna (type 52010193
WIRA-70-KRAI-ETSI): RHCP / LHCP/ horizontal linear / vertical linear
One can choose between static polarization and automatic switch-over. As the Kathrein-RFID Antenna In-
terface © KRAI is transmitted over the standard antenna cable, no additional lead or connection is required
to control the new antenna types.
The Kathrein RFID © KRAI system permits the cascading of up to 8 SMSH antennas at a single antenna
port. This allows selective access to up to 32 individual antennas. This allows the reading result to be linked
to the antenna recognition (e.g. antenna 3 (5)) and be output.
With the new © KRAI product series Kathrein has introduced a revolutionary system.

4.8. UART transmission (RS232, RS422, RS485 or similar)
4.8.1. Bit transmission layer (physical layer)
A full or half-duplex connection such as RS232, RS422 or RS485 is used for the physical layer.
4.8.2. Data link layer
Transmission is in frames and blocks. A block comprises a maximum of 256 frames. A frame comprises a
maximum of 256 bytes, of which a maximum of 250 bytes can be user data. The result is a maximum block size of
64000 bytes of user data.
The data link layer is used to safeguard the data between sender and recipient. The sender receives a response
from the recipient for each frame received. If the sender does not receive a response from the recipient within a
time window of 350 milliseconds after sending a frame, the frame sent is repeated until the error counter signals
the cancellation of the transmission. Structure of a frame
5A LL SS FF DD ... DD P1 P2
5A: Start code for synchronisation
LL: Number of bytes in the frame not including the start code
SS: Status byte
FF: Frame number
DD: User data
P1: 16-bit checksum low byte
P2: 16-bit checksum high byte Start code and synchronisation
The start code is used to synchronise the recipient to the sender. It further allows the receiver to synchronise to the
start of a frame when no data have been received for 15 milliseconds. Status byte
The status byte has the following signicance:
50: Data packet
A0: Response: “OK”
A1: Response: “Memory error” (the receiver was unable to allocate any memory for the data block received)
A response is only 3 bytes long and is not CRC checked.
“OK” response: 5A 02 A0
“Memory error” response: 5A 02 A1
4. Connections and displays
Installation manual Reader 25
Modications, misprints and errors excepted
4. Connections and displays Frame number
The frame number denes how many more frames there are in this data block. Only the rst frame in a data block
can be shorter than 256 bytes. Each additional frame must have a length of 256 bytes (length byte LL is FF).
It is therefore possible to calculate the block size from the rst frame number.
For example:
A block with 700 bytes of user data is to be transmitted. For this purpose the block is divided into three frames.
1. frame: 5A CD 50 02 – there now follow 200 bytes of user data – P1 P2
2. frame: 5A FF 50 01 – there now follow 250 bytes of user data – P1 P2
3. frame: 5A FF 50 00 – there now follow 250 bytes of user data – P1 P2
The receiver can use the frame number of the rst frame (here 02) and its length byte to calculate the block size
(block size = frame number * 250 bytes + length byte -5) (here in the example: 2 * 250 bytes + 205 bytes - 5 bytes =
700 bytes), and reserve an appropriate amount of memory for the data. User data
User data are the bytes in a frame that ow into the block transmitted. Checksum
The checksum is calculated using the polynomial x^16 + x^12 + x^5 + 1 with a pre-initialisation of 0x0000 from the
start code to the last user data byte.
4.8.3. Network layer
As the KBRP is a point-to-point protocol, there is no network layer.
4.8.4. Transport layer, session layer, presentation layer
Do not exist.
4.8.5. Application layer
The application layer transmits data blocks from 1 to a maximum of 64000 bytes.

4.9. LLRP-Protocol
Based on the communication protocol TCP, the Kathrein RFID reader with the Linux
operating system can handle the so called Low Level Reader Protocol (LLRP).
This is a by EPCglobal (http://www.epcglobalinc.org/standards/llrp) standardized com-
munication interface between RFID reader and a LLRP-enabled application software.
The default port for LLRP is 5084.
This LLRP protocol is roughly divided into the following parts:
Automatic query of the reader functions by the application software
Conguration of the reader functions by the application software
Triggering of read and write operations on the air interface by the application
Transfer of the found tag data to the application software
To start the LLRP application, please use the AppManager of the ReaderStart Sw.
There you can load the LLRP protocol engine with „Install App“ then start with „Start
To test the Kathrein reader with the LLRP protocol you can use the open-source pro-
gramming tool „Eclipse (IDE)“. With the so called LLRP Commander the Reader can
be controlled and operated.
Eclipse (IDE) and LLRP Commander are not part of the Kathrein RFID SW

4.11. Digital inputs and outputs
4.10.1. Frame structure
A frame is structured as follows:
Start + Data block + End
The start consists of 0xAA 0xBB 0x01 0x01, where the rst 1 is the data transmit byte and the second 1 a stuff byte.
The end consists of 0xAA 0xCC. If the byte 0xAA occurs in the KBRP frame, it must be doubled (0xAA → 0xAA 0xAA)
4.10.2. Port
The TCP communication port is the Port 4007.
4.10.3. Example
As an example the frame for “ASyncGetEPCs” is shown. The ID for this command is the “0x0111” which then causes
the frame to appear as follows:
0xAA 0xBB 0x01 0x01 0x11 0x01 0xAA 0xCC
4.10. Ethernet transmission
When communication to our reader is via Ethernet, a data transmission layer is also used, as for serial communication.
The transmission layer via Ethernet looks much simpler here, because the TCP/IP protocol already provides a
data security layer. All we need to add are the packet start and packet end, since TCP/IP is a streaming protocol.
The activation and evaluation can be performed using the software ReaderStart v2, with the DLL supplied, or by
access to the reader protocol.

Allocation of the GPIO interface cable (Order-No. 52010125, 52010126)
The digital inputs and outputs are communicated via two eight-pin sockets in A-coding with M12 connection
threads. The inputs are double isolated from the power supply of the reader and can be operated irrespective of
the polarity of the input signal. For this reason there is a common pin for the inputs (INP_CMN). The connection
variants for the inputs are shown below. Depending on the application, the power to the inputs can be double insulated
from the external power supply to the reader, or not double insulated from it.

Modications, misprints and errors excepted
4. Connections and displays
The outputs are also double insulated from the power supply to the reader and have a common pin (OUT_CMN).
If the double insulation is not required, the power supply can also be taken directly from the reader.
Please note that the load per channel is limited to a maximum of 0.5 A, and the total load across all the channels
must not exceed 1.5 A. The inputs and outputs are designed for a maximum voltage of 30 V DC. Further information
can be found in the data sheet for the reader.

For the connection to the RFID antennas, the reader has four antenna connections that are of reverse
TNC design. Please only use the cable from the accessories or equivalent cable for this connection.
Please only use cable suitable for the impedance (50 Ohm), as otherwise the performance of the reader will be
severely limited by the mismatch. If the mismatch is large, the reader may indicate a fault.
The reader has a 2-colour LED for the indication of the operating state. The table below shows the colours used
and the related operating state.
Red Green Operating state
Xashes approx. every 8 seconds Error during initialisation
