4.3 Operation
The test software “ReaderStart” for the RRUI4 is described in the section that follows. Before the
description addresses the user interface and the individual confi guration features and controls,
the principle of operation of this RFID reader system is described.
4.3.1 General
An RFID system comprises, along with a control computer and the actual reader, also the
antennas for the reader, the antenna connection cables and the tags. The fi gure below shows the
schematic layout of the system:
Figure: Schematic illustration of an RFID reader system
4. Software
16
The computer controls the reader via one of the available interfaces and receives over this interface
the EPCs and data from the tags read.
To read from an EPC tag, the reader emits an RF carrier via the active antenna and in this way
supplies the tag with power. If the information on the tag is now to be read, a connection to the tag
is established. For this purpose the tag is selected from a possible number of tags (singularisation).
For the transmission of data from and to the tag, the reader requests a handle from the tag. The rest
of the communication with the tag can be undertaken using this handle and the EPC read.
The tag's EPC is transferred from the reader to the PC and displayed on the PC with additional
information. This information includes, along with the time the tag was read, also the antenna used for
communication with the tag. It is always possible to communicate directly with the tag using this EPC,
as soon as the tag is in range of the reader.
The ReaderStart application communicates with the reader using the DLL supplied. On the
user interface it provides information on all the unit's functions of relevance to the user. Every
connection between the application and the reader over the various interfaces in the reader is made
using this DLL. The functions that can be used are listed in the header fi le “ReaderDll.h”.
4. Software
4.3.2 User interface description
The program is started by double-clicking “ReaderStart.exe”. After a splash screen, the program's
user interface appears.
Figure: ReaderStart user interface
Menu bar
Tab
Status box
The status box contains current messages from the reader and can be seen on every tab.
17
4.3.3 Establishing connection
The “Verbindung” (Connection) tab contains all controls for establishing a connection to the reader.
Depending on the unit, it is possible to establish a connection via RS 485 or RS 422, via USB or via
Ethernet.
4. Software
4.3.3.1 “ComPort” group box
The serial interface is used for the communication with the reader via RS 485 or RS 422. The
RS 485/RS 422 interface card supports the standard data rates of the serial interface on a PC. A level
converter is also required for the communication to convert the RS 232-compliant signal from the
PC into a differential RS 485/RS 422 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.
The required baud rate must also be set in the list box below. The com port is opened by clicking
the “Öffnen” (Open) button and the port is then no longer available for other applications. If
this port is already in use by another application, a corresponding error message is displayed.
If the port is free, the reader can be operated using this port.
4.3.3.2 “USB” group box
If an RRUI4 is connected to the PC via USB, the unit is installed in the system as a USB HID-
compliant device. Correct installation can be seen in the application if a number appears in the drop-
down list box after reader installation. This number is unique for each reader. If several readers are
connected to the PC, the related reader can be selected on this menu. The connection between
the reader and PC is now established by clicking “Öffnen” (Open).
4.3.3.3 “Ethernet” group box
The application offers two ways of establishing a connection to the reader via Ethernet (only
possible on readers with Ethernet interface). 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.
To integrate the reader into a corporate network, please contact your administrator who will be
able to allocate you a spare IP address. If you want to connect the reader directly to the PC,
please use a cross-link cable (crossed network cable). You can use a standard patch cable for
connecting to the PC using a hub or switch.
If you have a spare IP address, you must allocate this address to the reader. For this purpose a
connection must be established to the reader (e. g. via USB). It is now possible to enter the IP address
on the “Konfi guration” (Confi guration) tab. After the confi guration has been saved it is possible to
communicate with the reader using this address. For this purpose, mark the “IP-Adresse” (IP address)
box and enter this address. The connection is established by clicking the “Öffnen” (Open) button.
For the connection using a DNS name, there must be a correspondingly confi gured DHCP and
DNS server in the network. If the reader is registered on the DHCP server and the DNS server, it is
also possible to connect to the reader using a network name. For this purpose, select the “Name”
box and enter the name agreed for the reader. The connection to the RRUI4 is established by
clicking the “Öffnen” (Open) button.

4. Software
4.3.4 Konfi guration (Confi guration)
On the “Konfi guration” (Confi guration) tab it is possible to set all the RF parameters for the reader
as well as to set the parameters for the communication interfaces. It is also possible to read and
write the licence key for the reader on this tab.
If a connection has been established to the reader, the settings in the reader are read when
the “Konfi guration” (Confi guration) tab is opened. The confi guration can also be read manually
from the reader by clicking the “Konfi guration lesen” (Read confi guration) button. During this
process all settings in the user interface are overwritten. The current settings are saved in
the reader by clicking “Konfi guration schreiben” (Write confi guration). This action includes all

4.3.4.1 “HF-Einstellungen” (RF settings) group box
In this group box the radio frequency parameters, such as the transmission power, transmission
channel (EU only) and the spectrum can be set. The applicable standards in the related approval
region are to be observed when setting the transmission power.
4. Software
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.
Sendeleistung (Transmission power)
The RFID reader's transmission power can be set separately for each antenna or all antennas at
the same time. If the “Alle Antennen gleiche Leistung” (All antennas same power) check box is
selected, 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.
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. 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 + DCable - GAntenna
PReader ... Reader's transmission power in dBm
PERP ... Radiated power referred to a half-wave dipole in dBm
DCable ... Cable attenuation in dB
GHW ... Gain of the antenna referred to a half-wave dipole
The cable attenuation is the length-dependent attenuation of the cable at the related frequency:
DCable = L * Dper m
DCable ... Cable attenuation in dB
L ... Length in m
Dpro m ... Attenuation in dB/m
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.
20
4. Software
In the European approval area, the radiated power must not exceed 2 W ERP. This fi gure refers
to a half-wave dipole. The relationship shown below exists between an isotropic radiator (dBi)
and a half-wave dipole.
GHW = Gisot - 2.14 dB
GHW ... Gain referred to half-wave dipole
Gisot ... Gain referred to isotropic radiator in dBi
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 - 2.14 dB - 3 dB
GHW ... Gain referred to half-wave dipole
Gisot ... Gain referred to 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 + DCable, with Pcond ≤ 1 W and Gisot ≤ 6 dB
PReader ... Reader's transmission power in dBm
DCable ... Cable attenuation
Gisot ... Gain of the antenna in dBi
Pcond ... Power at the antenna input in dBm
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.
Kanalwahl (Channel selection)
The reader transmits, dependent on the approval region, 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 must be selected on the “verfügbare Kanäle” (Available
channels) list for each channel the reader is to use. In this manner it is possible to avoid from the start
the usage of specifi c channels on which there is interference. In the case of a read command, the
reader searches for a spare transmission channel using LBT (Listen Before Talk). The reader starts
to search through the channels in ascending order. As soon as it fi nds a free transmission channel,
the reader starts to send its data on this channel.
21
Antennenkonfi guration (Antenna confi guration)
If all antenna outputs on the reader are selected, the reader attempts to read the tags in the fi eld
starting at antenna 1. Once no more new tags are found, the reader switches to the next antenna. It is
then again attempted to read all tags that reply to the reader's request. This process starts again from
the beginning after the last antenna.
If not all antennas are selected, the reader starts its request with the lowest antenna selected and
then switches through all antennas selected in ascending order.
It is possible to quickly select the antennas to be used on the “Test Gen2-Funktionen” (Test Gen2
functions) tab by forming an antenna group. For this purpose a selection must be made from the
active antennas by selecting the check boxes in the “Antennengruppe” (Antenna group) list. The
resulting group can now be selected using the “Test Gen2-Funktionen” (Test Gen2 functions).
The “Tags lesen” (Read tags) function is then only performed for this group.
Modulationstypen (Modulation types)
The modulation type can be switched between “Zweiseitenband” (double sideband) and PR-ASK
modulation in this drop-down list box.
Trägerabschaltzeit (Carrier shut down time)
The “Trägerabschaltzeit” (carrier shut down time) defi nes how long an RF carrier remains enabled
after the last command from the reader to the tag. If the time between two commands is long, it is
recommended to shut down the carrier to save energy and to avoid using the channel unnecessarily.
The shut down time can be set as an integer from 0 to 65535 seconds.
Mögliche Kommunikationsprofi le (Possible communication profi les)
If the confi guration is read, the communication profi les that can be used are read from the reader
and can be selected in the drop-down list box. The profi le defi nes the speed at which data are
transmitted to and from the tag. The person confi guring the reader thus has direct control over the
performance of the reader and the spectral characteristics of the transmission signal.

The order with which the channels are to be searched using LBT can be defi ned with the aid
of the selection of the preferred channels. The channels selected here are searched fi rst in
ascending order. If a spare channel is not found in the preferred channels, the remaining channels
are searched.
In the USA the RF power connected at the antenna input is related to a minimum number of
channels used.

4.3.4.2 “IO-Modul-Einstellungen” (IO module settings) group box
The reader is supplied either with an Ethernet or RS 485/422 interface depending on its features.
The confi guration of the interface can be adapted to the application using this group box.
Note
Incorrect settings can result in an interruption of the connection to the reader. The settings on
readers without USB can only be reset using an interface that matches the confi guration.
Figure: Part of the “Konfi guration” (Confi guration) tab
The card type for the reader can be set in the “Modultyp” (Module type) drop-down list box. The
remaining confi guration boxes in this group box are activated depending on the card type selected.
The following settings are possible:
- Autodetect:
The reader detects which I/O card is installed. The settings for the card detected are made in
accordance with the default confi guration (see section 4.3.4.3).
- RS 485:
The reader expects a corresponding RS 422/485 card. To set the interface type from RS 485
to RS 422, the RS 422 check box must be selected. It is also possible to enable pull-ups and a
terminating resistor in the receive and transmit path. The terminating resistor is imperative for
a reliable point-to-point connection. It should only be deactivated in RS 485/422 networks in
which the reader is not installed at one of the ends of the network. The data transfer can also be
made using two stop bits. The transmission speed is set in the “Baudrate” drop-down list box.
The parity is set in the “Parität” (Parity) box to suit the required setting.
- Ethernet:
If the “Ethernet” module type is selected, it is possible to enter the network name and IP address.
If DHCP is activated by selecting the check box with the same name, the reader logs into the
DHCP server in the network and gets its IP address from there. For this reason the “IP-Adresse”
(IP address) fi eld is also deactivated. An appropriate network name can still be entered; this name
can then be used to communicate with the reader in the network provided there is an appropriately
confi gured DNS server.

4.3.5 Test Gen2-Funktionen (Test Gen2 functions)
This tab makes it possible to test the individual reader functions. This includes, along with the
functionality in accordance with the EPC-Gen2 standard, e. g.: reading individual tags, writing
tags, setting passwords, also the measurement of the temperature inside the reader, as well as
the selection of the antenna.
Along with the “Temperatur lesen” (Read temperature), “EPCs lesen” (Read EPCs) buttons,
antenna selection and the box for displaying the EPCs read, this tab comprises the “Schreibe EPC
auf einzelnen Tag” (Write EPC to an individual tag), “Passwörter verändern” (Change passwords),
“Daten lesen schreiben” (Read write data), “Lock Tag” and “Kill Tag” group boxes. The sections
that follow explain this functionality in more detail.
Figure: The “Test Gen2-Funktionen” (Test Gen2 functions) tab
4.3.5.1 Reading tag
To read a tag on this tab, the “EPCs lesen” (Read EPCs) button must be clicked once the reader
is correctly confi gured. The reader now tries to read once all the tags in the fi eld of the selected
antenna. If the number of antennas is limited in the “Antennenwahl” (Antenna selection) drop-
down list box, only the available antennas or the antenna group set in the confi guration are
used for reading. The EPCs from the tags read successfully are displayed in the fi eld below.
The status box shows the EPCs of the tags read in relation to the antenna used.
The actual temperature inside the reader can be requested using the “Temperatur lesen” (Read
temperature) button. This function is for information only.

There are two ways of writing a tag's EPC in this group box. The fi rst is to change an existing tag
or to write to any tag in the fi eld.
“übernehme EPC” (Copy EPC) button
Figure: The “Schreibe EPC auf einzelnen Tag” (Write EPC to an individual tag) group box
26
4. Software
To change an existing EPC, the EPC must be selected in the “gelesene EPCs” (EPCs read) box.
The EPC is copied to the editable “EPC” box using the “übernehme EPC” (Copy EPC) button. There
the code can be changed either manually or using the “auto-inkrement” (Auto-increment) function;
the latter function increases the EPC by 1 each time the code is written successfully to a tag. The
“Schreibe EPC” (Write EPC) button transfers the number from the EPC box to the selected tag. If the
“EPC auf einen Tag schreiben” (Write EPC to a tag) button is used it is not necessary to know the
EPC on the tag. But there must only be one tag in the fi eld. This tag is detected by the reader and
the new EPC written to the tag. If the data area on the tag is protected with an access password,
this password must be entered in the “Passwort” (Password) box prior to the write operation.
4.3.5.3 “Passwörter verändern” (Change passwords) group box
According to the EPC standard, the access to the individual memory areas of a tag can be restricted.
The confi guration of which area is protected is defi ned in the “Passwörter verändern” (Change
passwords) and “Lock Tag” group boxes.
The access password and the kill password can be set in the fi rst group box. For this purpose the
old password must be entered fi rst. If a password has not been set, 0 must be entered. The new
password is entered in the “neue Passwort” (New password) box. The old password is replaced
with the new password by clicking the “Schreibe Passwort” (Write password) button. To set a kill
password, the access password must also be entered. The kill password is only needed for the fi nal
deactivation of the tag.
Note
The tag will be unusable after a “Kill Tag” command!
The new kill password is entered in the fi eld and transferred to the tag by clicking the “Kill
Passwort setzten” (Set kill password) button. Once this process has been completed, the new
password applies.
4.3.5.4 “Lock Tag” group box
In this group box, the access to individual tag data areas can be inhibited as per the EPC standard.
Access is then only possible using a valid password, or is no longer possible until the inhibit
is removed.
The access is confi gured in 3 steps:
1. Enter the access password
2. Set mask bits for the “Kill”, “Access”, “EPC”, “TID” and “User” data areas. If a check box is selected,
the related action bit is defi ned as per the setting, otherwise it is ignored
3. Set action bits for the data areas. The function of the bits for each area is identical and is shown
in the following table. A set bit is the same as the selection of a check box on the user interface
You will fi nd more detailed information on these bits and the related memory areas in the latest
version of standard “Radio-Frequency Identity Protocols Class-1 Generation-2 UHF RFID” from
EPC global.

After the defi nition of the functionality, this confi guration is written to the tag by clicking the
“Lock für Tag” (Lock for tag) button. This confi guration is transferred to every tag in the fi eld with
the same access password using the “Lock für jedes Tag” (Lock for every tag) button.
4.3.5.5 “Daten lesen und schreiben” (Read and write data) group box
Each memory bank in the tag can be read and written in this group box. The exact layout of
the tag memory is given in the EPC Global standard “Radio-Frequency Identity Protocols
Class-1 Generation-2 UHF RFID”.
4.3.5.6 “Kill Tag” group box
The tags can be fi nally deactivated in this group box.
Note
The tag will be unusable after a “Kill Tag” command!
To start this operation, the correct kill password must be entered. The “Kill Tag” button only
deactivates the tag marked on which the kill password matches the password entered. Groups
of tags can be deactivated using the “Kill jedes Tag” (Kill every tag) button; here it is also required
that the tags have the same kill password.
4.3.6 Test Lesefunktion (Test read function)
Using the functions available on this tab the “Read Performance” can be tested. Part of the tab
is designed for cyclically polling the tags in the fi eld.

The largest part of the tab is taken up by the “gelesene EPCs” (EPCs read) box. This box contains
a table that displays each tag read. Additional information is shown for each tag:
- Antenne (Antenna) This number is the same as the antenna port on the
reader via which the tag has been read
- Leseanzahl (Number of reads) Indicates the number of successful read processes
completed
- Anzahl Zyklen (Number of cycles) Indicates the total number of read cycles since the
start of the read process
- zuerst gelesen (Read fi rst) Time the tag was read for the fi rst time
- zuletzt gelesen (Last read) Time the tag was active in the fi eld for the last time
The right part of the tab contains various options that affect the reader's mode of operation.
The “Start” and “Stop” buttons start and end the reader's read cycle. The “Intervalllänge” (Interval
length) box defi nes how long the software waits after a read command until the next read command
is sent to the reader. The interval length can be between 0 and 9999 ms.

If there is a very large number of tags in the fi eld, the reader may take a very long time to singularise
and read the EPCs on the tags. In such a case the software may end the read process with a
timeout. In the “Readtimeout” (Read timeout) box you can defi ne how long the software waits for a
reply from the reader before the read command is declared invalid and the software outputs an
error message. This time is entered in seconds and can be a maximum of 99 seconds.
The “gelesene EPCs” (EPCs read) table can be completely erased manually using the “Clear” button.
The check boxes underneath this button make it possible to reset the table:
- Either on each start
- After a specifi c time in seconds
- Or a specifi c time after the last tag was read.
The related function is activated by selecting the related check box. The maximum waiting time
before the table is cleared is 999 seconds.
The “Bulk-Modus” (Bulk mode) changes the reading behaviour of the reader such that the EPCs
for the tags successfully read are not logged into the reader immediately after the end of a read
process. The reader automatically starts read commands on all available antennas until the time
stated in the “Lesezeit” (Read time) fi eld has elapsed. All the tags read are then transferred to the
software. If there is a large number of tags in the fi eld, the transmission time from the reader
to the PC is optimised using this function and the performance of the reader improved.
The “Antennen unabhängige Anzeige” (Antenna-independent indication) check box makes it
possible to suppress the multiple indication of tags that are read via more than antennas. With
this indication, each tag, irrespective of which antenna is used to read it, is added to the EPC list
and counted only once.
A trigger event can send the read command to the reader using the “Sensor Read” function.
For this purpose a suitable signal must be applied to a spare serial port on the PC. If the condition
is met, the PC sends read commands to the reader until the condition is no longer met.
To set the correct signal level, a check box can be used to switch between RTS and CTS. CTS is the
input as per table 7. RTS is set to the required active level. The correct level to trigger the trigger event
is set on CTS using the check box.
To confi gure this function, the level for RTS and CTS must fi rst be defi ned. In the next step, the
required port must be selected in the drop-down list box. The com port is opened by selecting the
“Sensor Read” check box, and the related settings made.
