Introduction
2.1.
The reader
English
The Kathrein RFID (Radio Frequency Identification) 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.
2.2.
RFID system
An RFID system consists of the control computer of the actual reader, antennas, antenna connection cables and the
tags. The figure below shows the schematic structure of the system:
RS232
RS422/485
Ethernet
By the ETL and ELC
Reader is an industrial
PC with Linux operating
system is integrated.
Figure: continuous operation ETL and ELC RFID 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 identified 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
field with energy.
If the information in one tag should be read, this tag should be first 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.
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.

Kathrein RFID Antenna Interface © KRAI
With the new © KRAI product series Kathrein has introduced a revolutionary system.
By using Kathrein © KRAI antennas, reading rates can be increased by 33% compared to simple circular
antennas.
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
antennas.
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 Interface © 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.

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.

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.
4.8.2.3.
Status byte
The status byte has the following significance:
50:

Response: “OK”
Response: “Memory error” (the receiver was unable to allocate any memory for the data block received)

4.8.2.4.
Frame number
English
The frame number defines how many more frames there are in this data block. Only the first 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 first 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 first 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.
4.8.2.5.
User data
User data are the bytes in a frame that flow into the block transmitted.
4.8.2.6.
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.

Ethernet transmission
English
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.
4.9.1.
Frame structure
A frame is structured as follows:
Start + Data block + End
The start consists of 0xAA 0xBB 0x01 0x01, where the first 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)
4.9.2.
Port
The TCP communication port is the Port 4007.
4.9.3.
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

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.

Communication
English
The communication tab groups together all the functions for establishing connections and configuring the
interface cards. The various communication connections are grouped under 3 headers, COM for serial
connections via the COM port (RS232/485/422), USB for connections up to version USB 2.0 and Ethernet for
connections via TCP/IP.
When the connection is established, the program interrogates the information about the installed I/O cards. The
information can be viewed and changed via the I/O card configuration.
Figure: Tab for the Communication by Ethernet I/O card
6.1.1.
COM header
The serial interface is used for communication with the reader via RS232, RS485 and RS422.
The RS485/RS422 interface card supports the standard data rates of the serial interface on a PC. A level converter is
also required for communication to convert the RS232-compliant signal from the PC into a differential RS485/RS422
signal.
A serial COM port on the PC can be opened in this group box. For this purpose the correct serial interface must
be selected in the Port drop-down list box. Only the ports available on the PC are displayed in this list box.
It is not checked whether this port is already in use by other applications.
In the menu below the desired Baud rate must still be set, and if used, the flow control setting. The COM port is
opened by clicking on the Connect button, which blocks it for other applications. If this port is already being
used by another application, a corresponding error message is output. If the port is free, the reader can be
operated using this port.
Pressing the Disconnect button breaks the connection and releases the interface again.

If a RRU4 is connected to the PC via USB, the unit is installed in the system as a USB HID-compliant device.
Correct logging in can be seen in the program if a reader number appears in the drop-down menu. This number is
unique for each reader. If several readers are connected to the PC, the related reader can be selected on this menu.
Clicking on Open now establishes the connection between the reader and PC.
6.1.3.
Ethernet header
The Ethernet connection can be achieved by linking the reader into an existing network, or by a direct connection
between the reader and a control computer. For direct connection of the reader to the PC, a cross-link cable
is required, unless the LAN interface on the PC supports “auto-mdi-x”. Alternatively two standard patch cables
and a switch can be used.

Operating the reader
The user will be informed with the status messages about the progress of the reset process. The final message will be
„Reader with IP Address 192.168.0.1 …. (???????????) .
Note
From reader firmware 2.04, the reader in the ex-works condition has the IP address 192.168.0.1 with the network
mask 255.255.255.0. Reader versions earlier than this are configured for DHCP.
To integrate the reader into a corporate network, please contact your administrator who will be able to allocate
you a spare IP address and assign the correct network mask. Alternatively the reader can also be configured to
obtain an IP address automatically. For this service, referred to as DHCP, an appropriate DHCP server must be
operating in the network. You can obtain more details about this from your network administrator.
Note
The IP addresses of the control computer and the reader must be in the same IP range, but they must not be the same.
The network mask on the other hand must be identical.
In order to establish the connection to the reader, the program offers two options. On the one hand, it is possible
to communicate directly with the reader by entering the IP address, on the other hand it is also possible to
establish a connection using the reader's host name.
For the connection using a host name, there must be a correspondingly configured DHCP server and a DNS
in the network. After power up, the reader makes a DHCP request and logs on to the DHCP server. This assigns
the reader an IP address and reports the network name and IP address to the DNS server. If now the connection
has been established, the IP address of the reader is determined by an enquiry on the DNS server.
The establishment of the connection is achieved if the establishment of the connection is selected under the
Ethernet header, meaning the selection of the IP address or name. For this, the correct IP address or the host
name of the reader must be entered in the corresponding field. Pressing the Connect button then opens the
data channel to the reader.
If you wish to establish a connection via an IP address, the IP address field must be highlighted and
this address entered in it. The connection is established by clicking on the Connect button.

I/O card configuration
English
The communication interface settings can be changed using the IO card configuration. All available I/O cards are
displayed here in the form of tabs. Clicking on the respective tab opens the associated card and displays all respective
configuration parameters, together with the card type that was detected.
Under the IO card type header there is a drop-down menu, in which the card type can be set to Auto detect, Card not
used or to the actual card type. Automatic detection restores the interface to the default settings. What these settings
are is described in the following sections in relation to the interfaces. If the card type is set to not used, this interface
can no longer to used.
All card-specific configuration parameters are displayed on the card sheet when the recognised card type is set.
These parameters are described in the following sections for the respective card. The settings are saved to the
reader by pressing the Save changes button.
Note
The new parameters, provided nothing to the contrary is specified for the specific card, become valid only when the
reader has been restarted. If incorrect parameters are loaded, the reader can no longer be accessed!
6.1.5.1.
RS232
The serial interface supports communication to the EIA232 standard and, depending on the expansion stage, has five
outputs for activation of LEDs. The configuration parameters are split between the Port settings and Output headers.
Figure: Configuration of the RS232 card
Installation manual Reader

6.
English
Operating the reader
The communication parameters are grouped as follows:
Baud rate – the speed of the connection. All popular serial data rates up to 230,400 bps are supported
Data bits – the number of data bits transmitted per byte. The card supports 5 – 8 data bits.
Parity – a bit for security of the data transmission
If None is selected, this bit is not transmitted. For all other settings this bit is transmitted. The even or odd parity
checks whether the number of bits including the parity bit is even or odd. Based on this information the recipient
can determine whether a bit has been switched. Mark and space specify whether the parity bit should be
transmitted with a fixed 1 or 0. In this case no data transmission security is achieved.
Stop bits – specifies whether the transmission of a byte should be terminated with one or two stop bits.
Flow control – for readers with the appropriate interface, this allows specification of whether the synchronisation
between the PC and reader should be by software None or by hardware wires (Hardware).
Note
Note that for a point-to-point connection, the setting of this parameter must be the same for both participants,
otherwise no connection can be established. RS232 readers, whose serial interface is performed
via 4-pin M12 connector, do not support hardware flow control.
The RS232 card has a further five outputs, which can be used for activation of LEDs. The configuration parameters
for these outputs can be found under the Output header.
Note
Not all reader hardware issues support this functionality. Please check the reader data sheet for information.

Operating the reader
Each input channel has two configuration parameters available. The Invert logical input option negates the electrical
input signal and uses this status for processing in the reader. If the check is not set, the signal is used unchanged.
Depending on the sensor being used (mechanical or electrical switch), a debounce time in milliseconds can be assigned
to each channel.
The outputs from the card can be assigned various functions. Further parameters can be activated, depending on the
function selected. The following functions are available:
Off – the selected output is deactivated
On – the selected output is always on
1Hz frequency – the selected output flashes at a frequency of 1 Hertz
2Hz frequency – the selected output flashes at a frequency of 2 Hertz
4Hz frequency – the selected output flashes at a frequency of 4 Hertz
8Hz frequency – the selected output flashes at a frequency of 8 Hertz
RF on – the output is active for Turn-off time milliseconds as soon as the radio frequency is present at the antenna
First antenna to Last antenna.
Antenna error – the output is active for Turn-off time milliseconds as soon as an antenna error occurs at antenna
First antenna to Last antenna.
Tag found – the output is active for Turn-off time milliseconds as soon as a tag is found at the antenna
First antenna to Last antenna.

Protocol access – the output is released and can be activated with all KBRP commands for GPIO.
Note
If the output is not set to protocol access, it cannot be accessed when processing action lists. See the
GPIO functions section for more details on action lists.
Once all the settings have been performed, the changes are loaded to the reader by pressing the Save changes

RS485
English
In order to establish a serial symmetrical connection to the EIA-485 standard, a RS485/RS422 card is required for
the reader. In addition to the parameters Baud rate, parity and stop bits, which are identical to RS232, the tab for
configuration of this interface has certain other specific settings under the Port settings header.
The LED control is only possible with ARU reader.
Figure: Configuration of the RS485 card
The parameters have the following meaning:
Pull-up – when this parameter is set, the differential wires are pulled up with 120 Ohm to a fixed reference
potential (+5 V and GND). This procedure is recommended when the signal ratios between the communications
participants are critical.
Load resistor – terminates the differential wires against each other with 120 Ohm. This variant is required
when the reader forms the end point of the network.
RS422 – activates the RS422 mode of the interface card. This changes over the connection from 2-wire for
RS485 to 4-wire for RS422. This achieves a full duplex connection with differential RX and TX wires.
Note
Note that for a point-to-point connection or for connection of the participants in a network, the setting of this
parameter must be the same for both participants, otherwise no connection can be established.

The parameters have the following functions:
Name – Here the host name of the reader which is logged on to the DNS server is stated. The reader can be
addressed by this name as an alternative to the IP address.
DHCP – activates the automatic issuing of an IP address by a DHCP server; if the network has a configured
DNS server, the host name of the reader can also be used.
IP address – for manual issuing of the address. This parameter can be used only if the DHCP is deactivated
Subnet mask – for manual issuing of a network mask. This parameter can be used only if the DHCP is deactivated.
Keep-alive time – this time specifies the intervals of time at which the reader sends a data packet to check
whether the receiver is still available. If the connection to the reader is broken, the reader shuts down the
connection. If this parameter is deactivated (0 ms), the socket is shut down only when the reader is restarted.
Note
If no keep-alive time is set it may happen that the reader cannot take up any further connections because the
existing connections have not been properly shut down (e.g. following a breakage in the wire). In this case the
reader has to be restarted. It is recommended that the keep-alive time is used to check the connection between the
reader and PC.
The data are saved in the reader by pressing the Save changes button. The data are however not loaded to the working

Application
English
The Application tab enables quick and easy configuration of the Kathrein RFID Reader for a selected application. The
available applications are represented visually in the upper area of the tab by labelled pictograms. Under the Settings
header, the number of tags expected, the antennas to be used, the parameter set in which the configuration should be
saved and the values for max. read frequency and max. read reliability options are stated.
Figure: Application tab
When the button for the desired application is clicked, it glows green continuously. In addition the designation,
the properties and the settings of the selected application are displayed in the respective fields.
The following applications are available for selection in version 2.00 of the ReaderStart v2:

If there are more applications than fit on the screen, the buttons alongside the applications are activated to allow
scrolling.
When the max. read frequency is set, for every detection (inventory) all tags are reset in order to read
them afresh. Under some circumstances the time allowed for detecting the tags may be insufficient,
so that some transponders are not detected. The frequency for detecting the tags should then be increased.
When the max. read reliability is set, tags that have already been read are not reset at every detection
(inventory), provided they are still being supplied with power. This means that only those tags which
have not yet been registered are detected. The confidence that all tags are read is thus increased.
Clicking on the Apply settings button saves the settings that were made, as well as the settings for the selected application,
in the selected parameter set. This is done by first resetting them to the factory settings and thus overwriting the previous
configuration. This must be acknowledged. Success is indicated by a the Apply settings button glowing briefly, and by
display of a success message in the status window. If the process fails, the button glows briefly orange for a warning or briefly
red for an error (and if the failure was due to an entry being omitted, in addition the field that is lacking the entry glows red),
and by display of a warning description or error description in the status window.
If the settings have been loaded successfully, a switch can now be made to the Basic reading tab and the read process
can be started.
Note
If more than one hundred tags simultaneously in the field, the application can read or read safety frequency can be
optimized.
When reading frequency, the number of readings is optimized. It may happen, however, that the same day is read several times, since the max setting. Frequency of reading with each sensing (Inventory) will be reset every day to read it
again. It may happen that the time to collect all tags may not be enough and so some transponders are not recognized.
The frequency of the detection of the tag is thus increased.
For read security as many different tags to be read.
If the setting max. Reading Security selected tags that have been read are not reset each time detecting (Inventory),
provided that they continue to be supplied with energy. This leads to that not only registered tags are detected during
reading. The security to read all tags, thus increased.

Basic read functions
English
This index card is divided into two columns, the first column contains a table with information about the read tags, and
in the second column you can find the controls, which control the reading process.
Figure: Basic read functions tab
The table next to the Electronic Product Code (EPC), you can find the following information:
Length - indicates the length in bits of the EPC, valid lengths 0-496 bit
EPC - EPC of the tag in hexadecimal representation
Antenna - tag was read over this antenna post, valid values 1-4
RSSI - is the unitless (shown as having no units) signal strength of the tag response, valid values 0-255
Readings - shows how many times this tag has been read successfully
Cycles - indicates how often an inventory was started
Last reading - is the timestamp of the last reading of the day
First reading - is the timestamp of the first reading of the day
The appearance and disappearance of the day is shown in colour in the field for better visual effect.
When a tag appears in the field, the row is represented by the green tag information, when it disappears the row is red.
The control of the reading process takes place in the second column of the index card. A distinction is made between
two different modes. These can be selected by selecting „synchronous“ and „asynchronous“. The description of these
two modes is done on the following pages.
The second column can be sorted by the read result (unique) tags. This is especially useful in multi-antenna applications. For example, with a gate application with 4 antennas read per pallet with 100 tags, then the maximum number
of reading results will be 400. Since not all tags are read by all antennas, the reading results in general, will level off at
about 250. In order to detect how many different tags have been read, the selection „sort by unique tags“ can be made.

Operating the reader
The row "number of unique tags" specifies how many different tags were read.
When the day count is very high (> 200) the detection of the tags can be speeded up, by commanding the reader may
change to new "select command" (see EPC global standard (E)).
This can be tested by selecting "Expert Parameters" directly in read mode. If the read operation box is ticked with
"Transmit Select If No Filter Is On", a "Select" is sent in each "Inventory". This means that all the tags that are defined at
this time in the field will be reset. It can also happen that tags that have been read are sometimes reset and re-recorded
again. In order to capture only new tags, a renewed "Select" can be prevented. This tick box is cleared on "Transmit
Select If No Filter Is On" and thus all tags defined only once read. This selection result is that no time is lost due to a
re-read. Please note, however, that tags in which the read operation was interrupted, they cannot be retrieved! Thus,
it may be that not 100% of the tags are read. Therefore, this parameter should be used with care in order to achieve
top results.

6.3.2.
Synchronous mode
English
This mode is intended for applications when the requirements for timing are not so demanding. This mode allows
the facility to switch the carrier off during the idle times, thus saving power.
The inventory of the tags (the read process) is performed across all the antennas that are configured. Once all
tags in the field have been read on the last antenna, data are sent to the PC. The inventory of the tags is then
automatically retriggered by the PC.
The Pause after reading option specifies how many milliseconds the pause between two inventories should be. During
this waiting time the carrier can be deactivated. See section ((B)) „configurational manual reader“ for more information
about switching off the carrier.
In order to keep the time between inventories as short as possible in synchronous mode, data transmission between
the inventories can be dispensed with. That means that the reader saves all the tags that it finds in the field in
its internal RAM. After a configurable time this results list is sent to the PC. This time is given in milliseconds by
the Bulk read parameter.
The current reading performance is displayed under the item Tags per second.
Note
The read rate is influenced by many parameters; these include in addition to the selected broadcasting profile
with the respective data rates also application-specific data such as how many tags the reader should expect
in the field. You can optimise these parameters using the expert settings 1 and 2. There is more about this in
the following sections. If you are unsure whether the settings you have chosen are optimum for your application,
please contact KATHREIN Support.
If the tags that have been read are to be saved to a file, this can be done by activating the Save to file option. The
EPC, the length of the EPC, the antenna on which the tag was read, the RSSI valuetogether with the time stamp when
the tag was read are saved.
The data are then saved in a csv file in the Program directory. In the File menu, you can “change to the log file
File / Options / Path” under the location of the CSV file. The file can opened or deleted in the context menu
for this item.
6.3.3.
Asynchronous mode
This mode is intended for applications for which maximum performance is required.
The reader starts the inventory as quickly as possible, and at the end of an inventory it does not deliver every tag
that was read to the PC, but only those that had newly appeared in the field or newly left it. This allows the time
required for communication with the higher level to be minimised.
The timing of when a tag was reliably read in the field and when the tag no longer appears in the field can be
defined more precisely using parameters. Details of these ObservedThresholdCnt and ObservedTimeoutCnt
parameters can be found in section ((B)) „configurational manual reader“.
Note
The read rate is influenced by many parameters; these include in addition to the selected broadcasting profile

6.4.1.
Synchronous writing
In this type of writing the data can only ever be written selectively to one EPC. This is selected in the EPC ComboBox.
Clicking on the Refresh button detects once again all tags in the antenna field and adds them to the ComboBox.
When all necessary data such as password, memory bank and memory address have been input a decision can
be made whether to specify the data to be written or to generate them at random. If specified data should be
written, optionally a data mask can be specified. When using random data, the number of them should be stated
in words (16-bit).
Note
Right-clicking on the Data to write field opens a context menu, which allows the selected EPC to be copied into this
field.
Note
Right-clicking on the Data mask field allows this to be filled optionally with 0 or F according to the number of the data
entered to be written.
Clicking on Start starts the performance of the previously specified number of write attempts. The error-free
completion of all write attempts is once again indicated by the button glowing green and by a message in the status
window. If any necessary data are lacking, the button briefly glows red and the field lacking the data glows red
somewhat longer. The associated error message appears in the status window.

6.5.		GPIO functions
Readers with GPIO functionality offer the facility to set up small controls which trigger the reader for instance by a
light barrier or which trigger an action at the outputs of the reader by reading specific tags. Such an action might be
switching an output to control the flow of goods.
The GPIO function tab allows the user of the program the facility to load or switch inputs and outputs manually. For
more complex procedures, action lists can be created here, which execute a sequence of commands on the reader.
This list can then be linked to various inputs.
This configuration sheet is divided into 5 different headers. In order to perform settings on a card, firstly the card
number must be selected in the GPIO card drop-down menu. This shows only cards of this type.
Figure: GPIO functions tab
The Test output header can be used in order to selectively connect an output manually. In order to enable
this access, the respective output of this card must previously have been connected to protocol access (see
I/O card configuration). The output in the drop-down menu is now selected in the header, and time is defined
using the Duration parameter, until the output automatically returns to its idle mode. The connections can
now be made using the Set output on and Set output off buttons.
The inputs to the reader can be interrogated under the Read inputs header. Whether an input is set or
not is shown in the signal fields. A one-off read process can be triggered by pressing the Read inputs
button. If this interrogation should be performed automatically, this process can be started by pressing
the Read inputs cyclic start button.
To automate the processes, command sequences in the form of action lists can be stored on the reader. These are
triggered by a change of flank at the selected input on the respective GPIO card.
The action lists consist of a sequence of individual actions, which can be loaded in the form of an ML file in
the context menu of the Action item under the Action list. This file can be created or edited manually, using
a text editor. The syntax can be seen from the example. The individual actions can be selected from the
functions described in section 7 “Reader configuration”.
The file is saved in the folder “..\My files\Kathren Sachsen GmbH\ReaderStart v2\” and can be edited using a text editor.
In order to use the newly added actions in the program, the file must be reloaded into the context menu.
The action list must be selected from the drop-down list. The desired actions are now selected individually
from the action list and added to the action list in the sequence in which they are to be executed. Pressing the
Clear action list button clears down the selected list.

Note
When the action list has been created, it is assigned under the Assign input to action list header to an input and a
selected flank. If it is desired to assign the list to both flanks, the assignment must be made once for the positive flank
and once for the negative flank.
The assignment can be cancelled again by a restart/reset of the reader or by assignment of the No action list
item.
The action lists that are created are stored only in the RAM of the reader. On restarting the reader these lists are
deleted again.
For continuous operation of the reader, the commands for the digital inputs and outputs can be integrated into a software application. This application software can be run on an external PC or on the industrial PC ETL and ELC reader.

Pre-setting can be selected under the Current parameter set header. This is done by selecting a parameter set in
the drop-down menu. This parameter is now active and loaded, and the headers are updated. When all the desired
changes have been made, they can be saved. The changes to the settings can be discarded by pressing the Reload
configuration button. The parameter set can be reloaded by pressing the Load factory defaults.
Under the Transmission power header, the parameters of the transmission path can be entered; these include the
transmission power, transmission channel (only ETSI) and spectrum. The applicable standards in the related approval
region are to be observed when setting the transmission power.
Note
To operate the reader in accordance with the related national standards, the antenna gain and the cable
attenuation must be taken into account in the transmission power setting. In no circumstances is it allowed to
exceed the permitted transmission power. Failure to observe this instruction can result in non-compliant operation
of the reader rendering void the unit's type approval.
6.6.1.1.
Transmission power
The radiated power is limited in Europe in accordance with ETSI 302208 to 2 W ERP. In the FCC region, max. 1 W
connected RF power applies with an antenna gain of 6 dBi. If the antenna gain is greater than 6 dBi, the RF power must
be reduced accordingly. While the European standard refers to a half-wave dipole, FCC part 15 refers to an isotropic
radiator.
To set the transmission power, the length-dependent cable attenuation and the antenna gain must be included in
the calculation of the transmission power. An example for the calculation of the transmission power for Europe and
FCC is given in the following.
The following applies to the European approval region:
PReader = PERP + DKabel – GHW
PReader...Transmission power of the reader in dBm
PERP......Transmission power based on a half-wave dipole in dBm
DKabel.....Cable attenuation in dB
GHW......Antenna gain based on a half-wave dipole
The cable attenuation is the length-dependent attenuation of the cable at the related frequency:
DKabel = l*DdB/m
DKabel....Cable attenuation in dB
l...........Length in m
DdB/m.....Attenuation in db/m at frequency
The antenna gain is stated in various different units. These units include dBi and dBic. The units dBi and dBic refer
to an isotropic (spherical) radiator, where dBic refers to a circularly polarised isotropic radiator and dBi to a linearly
polarised isotropic radiator.
In the European approval area, the radiated power must not exceed 2 W ERP. This figure refers to a half-wave dipole.
The relationship shown below exists between an isotropic radiator (dBi) and a half-wave dipole.

If the gain of the antenna is referred to the polarisation of a circular isotropic antenna (dBic), the linear gain of the
antenna is 3 dB lower. As a result the transmission power can be increased by 3 dB.
GHW = Gisot – 2.14dB – 3dB

Gisot....Gain based on an isotropic radiator in dBic
In the FCC approval region, the RF power connected at the antenna input must not exceed 1 W. If the gain of the
antenna is higher than 6 dBi, the RF power connected must be reduced correspondingly. The reader's transmission
power is then:
PReader = Pcond + DKabel with Pcond ≤ 1W and Gisot ≤ 6dB
PReader...Transmission power of the reader in dBm
Pcond......Power on antenna output in dBm
DKabel.....Cable attenuation in dBm
GHW......Antenna gain in dBi
If the antenna gain is stated in dBic, the reader's transmission power can be increased by 3 dB.
The transmission power for the European variant can be set in 0.25-dB steps from 20 dBm to 33 dBm.
The heading provides separate fields for inputting the antenna gain and the attenuation.
Note
The antenna gain must be stated in dBic.
The RFID reader's transmission power can be set separately for each antenna or all antennas at the
same time. If the All antennas same power check box is set, the sliders for the other antennas are
set to the same power when a slider for the power for antenna 1-4 is adjusted. If this check box is
not selected, the power at the antennas can be set separately for each output.
Pre-defined antennas can be selected in the Antenna type selection drop-down menu. This selection sets
the antenna gain in the program, and limits the transmission power to the maximum value permitted for this
antenna. If Custom antenna is selected, the gain and power can be freely set.
The context menu allows the XML file to be opened, and if changes are made to the file also allows it to be reloaded.

Antenna multiplex configuration
English
The sequence in which the antennas are used to read the tag can be set under this header. If this antenna is not
activated, the system proceeds to the next entry on the multiplex list. For asynchronous operation of the reader,
the exposure time on the antenna can also be specified. See section ((B)) „configurational manual reader“,
sections MultiplexingAntennaport and MultiplexingExposureTime for more details.
6.6.1.3.
RF settings
Depending on the approval region, the reader transmits in the frequency range 865 MHz to 868 MHz for Europe or
902 MHz to 928 MHz for USA.
In Europe the number of channels to be used can be limited. For this purpose the related check box
for each channel the reader is to use must be selected on the Available channels list. In this manner
it is possible to avoid from the start the usage of specific channels on which there is interference.
Each read command connects the channels under country-specific conditions and in accordance with the selected
communications standard. The reader then starts to search through the channels in ascending order.
In the Communication standard drop-down menu, when necessary and when permitted by the reader, the reader can
be switched to a different country-specific communications standard.The device version governs the communications
standards that are permitted.
The modulation type can be switched between double sideband and PR-ASK modulation in this drop-down menu.
The communications profile is critical for the data rate and the read reliability. This option allows the technician to
directly influence the performance of the reader and the spectrum of the signal. The profile names contain basic
orientation on the transmission and reception data rates.
Note
A special data rate may be necessary, depending on the tag used. Please contact Kathrein (rfid@kathrein.de) for
further details.
The “Time until carrier stand-by” parameter specifies how long the carrier of the reader remains active on the air
interface after the last action. Once this time has elapsed the carrier is switched off.

Initial Q value – reflects the number of tags expected in the field. (see ((B)) capital2.4.2. “InitialQ”)
Sel – specifies whether other parameters are of interest for an inventory of the tag population, or not. (see ((B))
capital 2.4.10. “QuerySel”)
Sessions - this configuration parameter instructs the reader the session with which it should work. (see ((B))

Get all EPCs
To read a tag in this menu, the Get all EPCs button must be clicked once the reader has been correctly
configured. The reader now tries once again to read all the tags in the field of the selected antenna.
If in the Antenna selection drop-down menu the number of antennas has been restricted, reading will
now be performed using the currently selected antenna, or using the antenna selected with All in the
Expert settings 1.
The EPCs from the tags read successfully are displayed in the field below. For the following operations, a tag can be
selected from this list by clicking on it.
6.7.2.
Write EPC
The EPC of the tag can be altered as desired under this header. For this purpose an EPC in hexadecimal format
must be entered in the New EPC field.
Note
Comply with the maximum EPC length supported by the tag - if this is exceeded the tag will return an error.
If the requirement is only to amend an existing tag, this tag can be loaded to the field by pressing the Apply selected
EPC button. Now the EPC can be changed manually, or by using the Auto increment option can be increased by one
at each write event.
The write event itself can optionally be executed on this tag by pressing the Write EPC to selected tag button. At this
time there may be several tags in the field, but at least one tag from the list must be selected. The second option is to
write the specified EPC without a tag being selected. When using this function, make sure there just one single tag in
the field.
6.7.3.
Change password
The EPC standard see ((B)) specifies that the tag should have two modes, the open and the secured state.
In the open state, operations can be performed on the tag if the associated memory areas are not secured with
a password greater than 0. If a password has been set and the Lock header has been used to set the memory
areas to password protected, the desired operation will not be executed, and the tag will report an access error.
Normal access remains available in areas that are not blocked.
If when the tag is accessed the valid password is given, the tag switches into the secured state and access is available
even in blocked areas. Setting the password and setting how individual areas are blocked is performed under the
Change password and Lock headers.
Under the first header, the password for restricting access to the tag and the password for deactivation of the
tag are set. The access password can be used to restrict access to the tag in the open state. Depending on the
configuration under the Lock header, parts of the tag can be provided with completely or partially restricted access
rights.
The deactivation password is required to deactivate the tag permanently by means of a Kill command.
Note
After a Kill tag command, the tag will be unusable.
To change the password, the current password must be given. If no password has yet been set, the
default value is 0. The new password is entered in the field of the same name, in hexadecimal format.
Clicking on the Set password on selected tag button replaces the old password with the new password.
The deactivation password is entered in the field of the same name by clicking on the associated button.
If the password is changed and the memory area in question is already protected by the access password, in addition
to the new password the access password must be entered in the Current password field.

Read/write data
English
This header supplies detailed access to all the data areas of the tag. Access is obtained by entering the selected
memory bank, the address within the memory bank and the number of words, expressed as 16-bit words.
If data are to be written, they must be entered in the Data to write field. The data mask allows only
individual bits on the tag to be changed. To do this, the mask must be entered in the Data mask field. The
reader uses this mask to change the data read from the tag at the points where 1 bits are written in the
mask, and writes the result back into the tag. The desired data can optionally be written to a single tag
in the field or to all tags in the field. If they are written to all tags in the field, these tags must all have the same
configuration (lock and password).
The header also offers the facility to read data from the selected tag or from all tags in the field. If the tags in the
field have differing passwords and are configured differently, the data must be read by individual tags.
The next section deals in more detail with the saving of the individual memory areas.
6.7.5.
Lock
The EPC Gen 2 standard provides security mechanisms for the tag data areas. This allows individual memory areas
and functionalities of the tags to be provided with a password to protect it against access and/or changes.
Under the Lock header, the mask that specifies access to the areas in accordance with the EPC Gen 2 standard can be
customised to suit the application. If no changes are required for an area, No change must be selected in the respective
drop-down menu. The areas are grouped as follows:
Deactivate – specifies whether or not a deactivation password is necessary for deactivating the tag. Further
details can be found in ((E)).
Access – specifies whether an access password is necessary for accessing a tag. If no access password is set,
the TAG can be addressed in the open state condition. Further details can be found in ((E)).
EPC – allows specification of whether or not the access password is necessary for changing the EPC.
TID – this area contains general information about the tag. This area can also be protected against user access
by setting the access password.
USER – if the tag has a memory area provided for user data, these can be protected by setting the access
password.
The respective items in the drop-down menu are divided into access blocks, which prevent reading and writing, and
write blocks.
Note
If the option with the suffix is permanently selected, this option can no longer be changed. Further details can be
found in ((A)) „communication protocol“.
Clicking on the Lock selected tag button loads the mask that was created to the list of the selected
tag. Alternatively all the tags in the field can be blocked, on the precondition that the tags all have the
same password.
Note
Wrongly configuring the Lock header can render the tag unusable.

The choice of configuration options depends on the types of the connected antennas. The category polarisation is for
antennas with polarisation switching, and the cable attenuation category is available for use by SmartShelf antennas.
Depending on the features that are integrated in the antennas LEDs can be controlled / configured under the section
LED.
Figure: Example WIRA with KRAI function and LEDs
In the polarisation section, the polarisation modes RHCP, LHCP, and the horizontal and vertical positions of the panels
can be set. If there are several types of polarisation selected at the same time in the check boxes, then the antenna
configuration changes after every inventory (read cycle) in the specific given order.
Using the button “Read Polarisation” the stored information from the Reader can be called up and using the “Set Polarisation” button a new input configuration can be stored.
The configuration of the LEDs in the LED section is analogous to the description of the functions in Section 6.1 to the
tab communication, heading IO-Card configuration/RS232. The features are as follows:
1 - Off - the selected LED is off
2 - On - the selected LED is always on
3 - RF on - the LED is active when the high frequency is fed to First to the Last antenna.
4 - Antenna Error - The error LED flashes/displays off-time in milliseconds when an error occurs in between the First
and Last antenna
5 – Tag found - The error LED flashes/displays off-time in milliseconds whenever a tag is found on the antennas
6 - Operation successful tag - the output is active for milliseconds at switch off time as soon as an operation on the tag
was successful on the First to the Last antenna.
7 - Protocol - the LED can be directly switched on and off via the protocol.

For cascadable SmartShelf antennas an absolute attenuation value is to be entered under the heading “interim cable
loss” (in 0.25 dB steps) for the lines between the antennas. The given value is set with “interim cable loss” to the reader.
Conversely, this can be called up from the reader using the button “Read interim cable loss”.
Note
For cascading smart shelf antennas, it is necessary to use cables with the same attenuation (cable length). Otherwise
the TX-power of the antennas that is derived from the intermediate cable attenuation is not calculated correctly.
Furthermore, the value of the intermediate cable loss should be correct, so that the output power can be correctly calculated and fed accordingly.
The libraries and headerfiles to support the software integration of the reader into existing applications can be found
on the CD in the /API directory. The user can choose the appropriate library for the target system (windows/ linux/ ELC/
ETL).
As another way of integration the user can implement the KBRP protocol according to the specification ((A)).
The example projects are located in the directory RFIDDemoApp. They demonstrate the programming of applications
for the reader under Windows, Linux and embedded Linux (ELC/ ETL) in C#, C++ and VB.Net. The examples are based
on the use of library functions. This examples are console applications. They show how to establish an connection to

Access Manager
Kathrein RFID solutions are characterised by ease of use and intuitive operation. They have extensive capabilities for
fast and secure ID applications of all kinds.
The devices of the ARU4 and RRU4 series have an optional integrated industrial PC platform based on Linux OS on
which the complete application control can be run directly on the device. A permanent data connection is not necessary!
The application software Access Manager V 1.0 allows user-controlled input and configuration of the transponder data
to be collected. Programming skills are not required! Digital inputs are thereby connected/linked to digital outputs and
then to defined EPC and TID data dependent on transponders.
For flexible and efficient usage of the transponder, Kathrein RFID systems are equipped with up to 4 digital inputs
that can be used to control features. This allows starting points of the application to be set, in which a photoelectric or
inductive ground loop is requested to enable the reading process. When registered in the system transponder these
can be detected and assigned to specific processes so that individual transponders are assigned appropriate authorisations. Depending on these decisions up to 4 digital outputs can be connected, e.g. to allow access by opening a
barrier or a gate.
As an example, on the Kathrein RFID homepage a demo version of ACCESS Manager can be downloaded. This demo
version is limited to 5 TAGs, and can be enabled if required for up to 500 transponders.

Finally, the unique transponders are assigned to the respective representatives of the user group, so as to achieve an
unambiguous classification and identification of vehicles and users.
This can be either a “Name”, “Username” or “ID”.
After expanding the input mask using the “>” button, the current transponder is read. This can always be re-launched
via the menu item “Update”.
With “Accept the selected tag” the EPC and TID of the selected transponder is transferred to the mask.
At the end the tab “Tag-user Group relationship” is used to assign the user to his user group.
Thus authorisations and the unique identifier are defined by the transponder.
Since the processing of the Access Manager runs immediately into a SQL database on the Linux part of the reader,
the transponder is also connected immediately. It is recorded in the corresponding driveways, after the triggering of the
trigger and depending on its corresponding privileges, the barrier is opened or access is denied. Upon completion of

Programming the Reader
For the integration of the reader into an existing application on Windows, Linux for operation as a standalone device
with embedded Linux appropriate libraries and header files are located on the CD in the subdirectory / API.
The user has the choice to use the appropriate target system library for Windows or Linux, or to implement KBRP
according to the supplied protocol specification ((A)) in its target application.
The RFIDDemoApp directory contains sample projects for Windows, Linux and embedded Linux that demonstrate the
programming in C #, C + + and VB.Net. These examples are based on the use of the library functions. This is a console
application that shows how the connection is established to the reader and how tags are read, GPIOs used and action
lists are built.
7.1.
Preparation
The examples have been tested on Windows 7 and Debian 6.0. Before the programs are compiled, the environment
must be adapted. Copy the folder / AP and / RFIDDemoApp in your user directory. For the preparation of programs for
an Embedded Linux, an Embedded Linux Development Kit must be installed. For more information on the installation,
please see Chapter 7.6.
Note
The example is based on the connection parameters from the factory default settings of the IO cards. This may need
to be adapted to your building in the reader and in the source code of the program.
The necessary libraries for the programs can either be stored in the respective program folder or the default library
folder of the operating system.
Now, the programs can be created using the following procedure.

The same source code can be used in Linux. A distinction is made as follows:
7.4.
Using the examples with Linux on a PC
The program is built in the / RFIDDemoApp / Linux with the command make. If the compiler finds all the necessary data,
the program Console Linux demo is created in the same folder.
LibReaderLib.so the library from the / API / Linux as root (su + root password) is still needed for the program, this file
can be copied to the / urs / lib (libReaderLib.so cp / usr / lib ) or will be stored in the folder with the source code. Then
the program with. / Console Linux demo can be started.
7.5.
Using on an embedded system
If the example is to be complied for the embedded system of an ETL or ELC reader, the ELDK must be installed for the
corresponding target System on Linux. The process for this is described in Chapter 7.7. The cross compiler creates the
program for the target system.
Note
The program created will only run on the target system.
To start the compilation process please use the file from the respective folder

The ELDK is a development tool, which includes cross-compiler tools and furthermore useful programs, included already compiled for the target (eg libraries or user programs) provides.
The CD / DVD contains the information necessary for the installation of .iso files which were current at the time of
creation of the CD / DVD. Newer versions can be downloaded at the following address
ftp://ftp.denx.de/pub/eldk/
(at the time of this writing, eg "version number" = 5.3). The directory structure is then given by
“Version-Nummer” → iso → eldk-“Versions-nummer”- “Architecture”.iso
It is important to note that the type of Reader RRU4 ETL files with the extension “~ armv4t.iso” (eg eldk-5.2.1-armv4t.
iso) and for readers of the type RRU4 ELC those ending with “~ armv7a.iso” (eg eldk-5.2.1-armv7a.iso) must be used.
To install the ELDK on the Linux system root privileges are required (su -> password). In the first step, you copy the
.iso file to a temporary directory, eg / tmp
Now the .iso file can be mounted to a different directory eg / mnt / tmp directory (the directory if not available, create
with mkdir / mnt / tmp)
mount -o loop /tmp/eldk-X.X.X-armvXX.iso /mnt/tmp
Next change to the mount directory
cd /mnt/tmp
and run the following command
./install.sh -s qte -r - armvXX
The ELDK is then installed by default in the / opt directory. There, the tools can be found. In the following directory
/opt/eldk-X.X.X/armvXX/sysroots/i686-eldk-linux
You will find the the Toolchain with the Cross-Compiler. In the following directory
/opt/eldk-X.X.X/armvXX/sysroots/armvXX-vfp-neon-linux-gnueabi
compiled tools can be found within the directory.
It is important that the last step is the unmounting of the .iso file
This can be completed using the following command
umount /mnt/tmp
The .iso file can then be deleted from the temporary folder.
rm -f /tmp/eldk-X.X.X-armvXX.iso

Installation Linux application
English
The reader is equipped with a separate module, running a linux on it. That gives the user the opportunity to install an
application that will start automatically after powering up the reader. The flash memory is divided into a writable and a
read only part of the file system.
This application note describes how to install a user application to the non-volatile memory (flash) of the reader. To
do this it is necessary to copy the application and the script, which starts the application, to the target and make both
executable.
Requirements:
RRU4-ETL-xx/ ARU-ETL-xx
Ethernet connection to the reader
For connecting to the Reader a client like putty ((F))
ftp client e.g. ftp (for Windows you can use the Explorer)
the user application
For writing and compiling an application please use the manual for the Reader.
First make a connection to the reader by opening a command shell:
C:\> putty –telnet ip_address 		
C:\> putty -ssh ip_address 			
for xxxx-ETL-xx
for xxxx-ELC-xx
where ip_address is the address of your reader. Per default this address is 192.168.0.1. The default login data is “root”
with the password “UHF-RFID-Dev”.
To copy a program to the reader ftp is used. Therefore the ftp server on the reader needs to be started. This can be
done via telnet by calling
# /usr/rfid/ftpstart
from the command line.
Now it is possible to establish a connection to the reader via ftp. To do so, open another command-shell, go to the
directory of the application to copy and start the ftp client e.g.:
C:\> ftp ip_address
where ip_address is the address of you reader. Login name is “root”, no password is required. If there is a problem
establishing the connection, check your firewall or ask your network administrator
To copy the application use
# put source /flash/destination
where source is the source filename and if necessary the directory from where to copy it. Destination should be the
filename that it should be called on the target. It’s important to copy the file into the “/flash” folder, because there is the
writeable file system.
After the file is put in that folder, the ftp is not needed anymore. With
# /usr/rfid/ftpstop
the server can be stopped. The FTP service is also stopped after a reboot.
On reader side the application file needs the permission to execute for all intended users. To change the permission
use
# chmod permission_owner permission_group permission_other application
where all permission_xxx consist of 3 bits, first read, second write and third execute. If the bit is set, the permission is
granted otherwise it is not. At least the application should be executable. Application is the name of the application on
the target. To give the permission to read and execute to all 3 groups it should look like this:
# chmod 555 application

the target. To give the permission to read and execute to all 3 groups it should look like this:
# chmod 555 application
So now we have an application in the non volatile memory on the target that is allowed to be executed. The next and
last step is to make it bootable by default after power up. During boot process the script inittab is called. This script
looks for a script named
startup
in the directory
/flash.
The linux will execute its content on every boot. Therefore we need to add the programcall in that script. Below is an
example shown, how this can be done from the commandline on the reader:
root@UHF-RFID-Dev:~# echo >> /flash/startup
root@UHF-RFID-Dev:~# echo # now lets start the application >> /flash/startup
root@UHF-RFID-Dev:~# echo /flash/application >> /flash/startup
The first line adds a newline into the startup-File, the second adds a comment to it. The third line calls the application.
When you need to modify the script, take use an editor that can handle Unix line breaks at the end of each line (0x0A),
the normal windows carriage return and linefeed in the script won’t work.
