Introduction
This chapter describes Transponders and their functions, the purpose of the Postal RFID System
and its uses. It also gives information on the RFID System S21 configuration principles.
Transponder Identification System
The purpose of a data capture or identification system that uses a Transponder as an identification
token is:
• To automatically identify animate or inanimate objects having attached a Transponder with an
unique identifier
• To ensure that information is available in a format that can be readily accepted by a computer
• To minimize the possibility of errors in the identification process.
The concept of Radio Frequency Identification (RFID) is presented in Figure 1-1.

Transponder Transponders are devices that receive an excitation signal, and respond by transmitting back a
message. Transponders that are used in identification systems are sometimes referred to as
electronic tags or tags.
Excitation Signal The excitation signal is a form of electromagnetic energy and can operate anywhere in the RF
spectrum from a low-radio frequency to infra-red light. It can also have a special signature (pattern,
coding, etc.) to avoid false or unwanted excitations. When there is no excitation signal, the
Transponder is dormant (in sleep mode). Transponders do not transmit information
involuntarily.
Response Signal The Transponder’s response can be a separate RF transmission or a supplementary modulation of
the excitation signal. The response signal contains information that allows you to identify: the
transponder (the object to which it is attached), the reading point which excited the tag, battery
status etc. Some or all of this information may be stored in memory that can either be pre-coded
and unalterable, or re programmable.
Reading Points Reading Points are installed at strategic areas on the site where you want to identify objects that are
passing within a specified range. Reading Points generate the excitation signal and receive signals
transmitted by the Transponders. Data captured from the Transponders is then transferred to the
main computer. In so doing, the Reading Point functions as a relay or an interface that transfers
data from the Transponders to the main computer and vice-versa.
Communication Links When using Transponders and Reading Points, two wireless communication links exist. They are:
Uplink - from the Reading Point to the Transponder, and Downlink - from the Transponder to the
Reading Point.
RFID System Automatic identification systems vary in their complexity. An example of a simple system is a car-
park barrier that provides automatic vehicular-access control. A more complex example is a
network of on-line Readers and Exciters that communicate with a host computer that is managing
an automated industrial facility.
Postal RFID System
The International Postal Corporation (IPC) required international end-to-end mail performance
monitoring to implement new management and financial control systems. This monitoring and
controlling is supported by an international agreement known as REIMS (Remunerating Exchanges
of International Mails).
The Postal RFID System was developed in response to the IPC’s requirements.
The main objective of the Postal RFID System is:
• To monitor the movement of the probe letters at key points in the system
• To supply evidence of mailing system performance
• To highlight problem areas.

RFID System S21 Configuration Principles
Introduction 1-3
By using a RFID system comprising of a population of Transponders and strategically placed
Readers and Exciters, you can electronically monitor the path of test letters through the collection
and delivery process, particularly at points between Postal administrations and their agents.
Each probe letter includes a RFID Transponder bearing a unique identification. The probe letters
are posted, sorted, and delivered in the same way as normal letters. As they pass pre-determined
points en-route (Reading Points/identification zones), the Transponders are identified. The
collected information is then read and stored on local computers. This information is downloaded
on demand to a Central Management System (CMS).
The Postal RFID System includes the following main specific equipment:
• Transponders PT21 carrying the identification data
• Exciters EX21 to generate an electromagnetic (LF) field that excites the Transponder PT21
• Readers RD21 to receive data transmitted by the Transponder PT21(UHF) and to relay this
information via the RS-485 interface to the main computer
• Power Supply TRM95 to power Readers RD21 and Exciters EX21 from the local AC main
supply.
IMPORTANT This manual refers to S21 features and equipment associated with RFID System S21.
RFID System S21 Configuration Principles
The RFID System S21 is highly configurable, allowing you to setup operational parameters for the
optimum performance of the System. The sections that follow give some basic information
regarding the RFID System S21 configuration. A detailed description of the configuration, with a
focus on an IPC implementation, is given in Chapter 5, Configuration and Operation.
Communication Links There are several communication links between the components of the RFID System S21. As a
general rule, all equipment attached to a particular link must have the same parameters settings to
communicate. Some communication links can be configured, others, however, have fixed
configurations, as follows:
• Reader-to-Transponder: excitation (LF=125.0 kHz - uplink) - configurable;
writing (LF) - fixed configuration.
• Transponder-to-Reader (UHF-433.92 MHz - downlink) - configurable.
• Reader-to-Exciter and Exciter-to-Reader (RS485_COM, RS485_SGN) - fixed configuration.
• Reader- to-Main PC and Main PC-to-Reader (RS232 or RS485) - configurable.
System Parameters Parameters controlling the RFID System S21’s configuration are logically organized in groups. For
a detailed explanation on the meaning and usage of the parameters, refer to the RFID System S21
Reference Guide. The parameters settings that control the hardware configuration, is described in
Chapter 3, Theory of Operation in the RFID System S21 Technical Guide. This chapter gives
reasons for using certain parameters for configuring the hardware.
System Code A Reader RD21 needs a System Code to function properly. You use the ISC parameter to set the
System Code the first time. The System Code is a specially encoded number that distinguishes the
RFID System from all other similar systems in use. By obtaining your System Code from Lyngsoe
Industries, you are guaranteed a unique System Code.

RFID System S21 Configuration Principles
1-4 Introduction
Reader Address When a Reader is part of a network, it must have a unique address. The address is set by the IAD
parameter. Once the Reader has an address assigned, it will only process commands with the
address field matching the Reader’s address. In this way, you can direct commands over the
network to a specific Reader.
Real Time Clock The Reader RD21 has an on board Real Time Clock. Make sure that the date and time are correctly
set. The time can be queried and set using the IUT parameter.
Receiving UHF Data The Reader needs to know the data format in which the Transponder is transmitting information to
properly receive and interpret the information. The Reader’s setting can be checked and modified
by the Group R parameters.
A simple method of matching an unknown Transponder with the Reader’s parameters setting is
given below:
1. Use the programming setup described in Chapter 6, Programming and Testing the Transponder
PT21.
2. Query the Transponder. (See the Q command).
3. Check the Transponder’s parameters using the Group T parameters.
4. Set an identical set of parameters for the Reader using the Group R parameters.
Reader Data Handling Data that is captured from the Transponder is usually stored in an internal buffer. It is then sent to
the monitoring equipment either voluntarily (if DAR=Y), or in response to a query command. You
can customize the format and the fields using the Group D parameters. By setting appropriate
values, you can greatly simplify the implementation of the monitoring software.
Reader Serial Port When setting the serial port parameters, remember that communication with the monitoring
equipment can result in a bottleneck in the RFID System. We recommend, therefore, using the
highest baud-rate available. Also, the line turn-around delay (STD parameter) can greatly degrade
the RFID System’s performance. This parameter must be set to 0, unless required otherwise. For
more information on the Group S parameters, refer to the RFID System S21 Reference Guide.
Reader Reset There are two main ways to reset the Reader:
• Hardware reset
• Software reset.
For the hardware reset, switch off the Reader’s power supply for a least 5 seconds.
![](/img.php?id=293359&img=bg11.png)
RFID System S21 Configuration Principles
Introduction 1-5
For the software reset, press the RESET button on the Motherboard MBD21 twice, or type the
command:
:RESET<Enter>
The software reset resets the Micro controller. The hardware reset resets the Micro controller and
runs a complete memory test for receiver REC21.
Exciter Address When an Exciter EX21 is part of a network, it must have an unique address. You can set the
Exciter’s address in a binary format between 0001 and 1110, using the S1 switch on the LFA21
board.
Once an address is assigned, the Exciter will only process commands with a matching address field.
In this way, you can direct commands in the network to a specific Exciter EX21.
Compatibility with
RFID System 95
RFID system S21 can be configured as an RFID System S95. By changing the configuration the
S21 can completely simulate the functionality of a S95 system. To implement this the following
must be done:
•On the Exciter EX21[board LFA21] - set jumper P1 on the S95 Position.
•On the Reader RD21 [board CTL21] - set jumper P3 on the S95 position.
•Upgrade Reader RD21 software to version 4.01.06 or higher.

Mechanical Assembling
To assemble the Exciter EX21, refer to the assembly drawing (900061), and complete the following
steps.
Assembling the LF
Antenna for EX21
The antenna frame consists of five separate segments, each with the following dimensions: two
pieces - 0.4m long, two pieces - 2.0m long, and one piece - 1.0m long. Each segment includes an
aluminum tube with an internal rubber hose. The segments are joined together using plastic
corners. The antenna cable (7-wire cable) runs through the rubber hose spacers inside the aluminum
tubes.
To assemble the antenna, do the following:
1. Starting with one side of the antenna frame that is beside the plastic enclosure (0.4 m segment),
place the corresponding rubber hose inside the aluminum tube, and run the antenna cable
through the rubber hose. Run the cable through a plastic corner, and secure the plastic corner
inside the aluminum tube using a rubber mallet.
2. Repeat Step 1 for each side of the frame, finishing with the last short segment (0.4m). You
should have a 1x2m rectangular aluminum frame with the antenna cable inside.
3. Terminate the antenna frame with the plastic base connectors.
4. Place the 90° brackets on each ends of the frame, and secure the frame against the plastic
enclosure using M6 screws, washers and nuts.
5. Connect the antenna frame to the LFA21 ground using the cable provided. Place one terminal
lug of the cable on the M6 screw and the other under one screw which holds the LFA21 board
in place as shown on the assembly drawing.
Note Always ensure that the ends of the antenna cable inside the plastic enclosure have at least - 110mm
respective - 360mm long. For more information, see the drawing 900061.
6. Use the self-drill screws (M3.5x9.5) to secure the 1 inch square aluminum tube in each corner
of the LF antenna frame, and to secure the 90° brackets against the aluminum tubes.
For tuning procedures refer to procedure 950031.

Reader’s Power-up Sequence
To verify the Reader’s power-up sequence, do the following:
1. Connect the power supply to the Reader.
2. Check whether the relay on the MBD21 board immediately clicks, and the green POWER
LED is on (See Figure 5.1).
3. Check whether the Reader performs the following power-on test sequence: the red DATA LED
on the MBD21 board remains ON for 6-7 seconds. Afterwards, the following sign-on message
is displayed on the PC’s screen:
Receiver REC21 (C) Copyright Lyngsoe Industries Ltd 2002.
Notes 1. If you did not assign a System Code identification number (SC) to the Reader, the DATA LED
will flash On and Off at a rate of 1.4 Hz. To set the System Code, type:
ISC=[your SC] <Enter>
2. If a string of unrecognizable characters appears on the PC’s screen, it means that the
communication link between the Reader and the PC is not set properly. Run the Learning
Procedure, as described below, to establish the correct settings.
Learning Procedure (Optional)
This a special mode of operation, specifically designed to allow a Reader to communicate with the
PC to which it is attached, by adapting itself to the serial frame format that the PC is using.
To force the Reader into the learning mode, follow the steps below. (See Figure 5-1).
1. Press the RESET button once.
2. Verify whether the DATA LED flashes at a rate of 2 Hz. This means that the Reader is in the
learning mode, and is waiting to determine the frame format sent by the PC.
3. Send a few characters to the Reader, for example, LYNGSOE.
4. When the learning process is finished, the DATA LED will start flashing at 1.4 Hz rate and the
following message will be displayed on the PC:
Learned: rate, parity, bits
where:
rate: is the serial data rate (baud) expressed as a numeric value, for example,19200.
parity: is a single character that reports the parity bit: N for no parity, Y for parity.
bits: is a single digit (7 or 8) that reports the number of bits per character.
5. Check the Reader’s current serial communication configuration parameters by using the group
of S parameters. You can change the settings for the PC or Reader so that the settings match

5-6 Configuration and Operation
Setting Up the Exciter’s Address
Your next step is to setup an address for each Exciter by using the S1 slide switch on the LFA21
board, as shown in Figure 5-2.
Figure 5-2: Setting Up the Exciter’s Address
The addresses must be sequential between 1 and 14. For example, if there are 4 Exciters, they must
be assigned addresses 1, 2, 3, and 4. Use the S1 switch to set the address to binary format. For
example, in binary format:
• address 1 is 00012
• address 2 is 00102
• address 3 is 00112
• address 4 is 01002
If the switch is in the ON position, the bit is set to “1”. Otherwise, the bit is set to “0”.The factory
default address setting is address 1 [00012]

LF Transmitter Output
Configuration and Operation 5-7
LF Transmitter Output
The type of LF excitation signals generated by the S21 depends on the parameter settings and the
position of “System” jumpers on the LFA21 and CTL21.
For “System S21” jumpers J1 (LFA21) and J3 (CTL21) are to be set on S21 position. The LF
excitation signal generated is of type EXID. This signal is a continuous OOK signal on 125 KHz.
The modulation is a fixed repetitive frame [Excitation ID] containing the address of the reading
point. (Reader Address).
For “System 95” jumpers J1 (LFA21) and J3 (CTL21) are to be set on S95 position. The LF
excitation signal generated is of type CSAC. This is a continuous signal as defined in the Appendix
C of the 95 Series RFID Systems User’s Guide.
To check the LF signal, refer to Figure 5-3 below, and do the following:
Figure 5-3: LF Signal Measurement
1. Connect the power to the Exciter.
2. To determine the Exciter mode of operation following the field application note instructions
provided with the equipment. For additional information or questions contact Lyngsoe
Industries.

5-8 Configuration and Operation
Note When more than one Exciter EX21 is used to create a wider excitation zone, a magnetic coupling
can appear. The phenomenon is explained in Chapter 4, Setup Guidelines in the RFID System S21
Technical Guide. The coupling generates an unwanted amplitude modulation with a frequency of
several Hertz, the modulation depth depending directly on the coupling. The installer has to
monitor the TAP signal and adjust the position of the EX21 frames to obtain a minimum unwanted
modulation depth. The installer can increase the distance between frames, level the frames in the
same plane, or place the frames with the shorter sides (1m) in parallel. The minimum amplitude of
VTAP due to unwanted modulation must be larger than 60Vpp.
4. Turn off the excitation field, by typing:
C<Enter>
The TAP voltage amplitude should be zero.
5. Turn on the LF field again, by typing:
B <Enter>
The TAP voltage signal should have the same value as measured in Step 4.
6. Set the wanted excitation mode.
To set a specific excitation mode, refer to Appendix C, Excitation Modes. If you want to return
to the initial excitation mode as determined in Step 2, you have to restore the values of the
parameters modified in Step 3.
For example, Lyngsoe recommends the following parameter values for the Conditional
Switching AC mode (CSAC) for the IPC installation:
RCS=Y; RES=Y; REM=C; RET=A; HCC=8; HCS=7; HE0=18; HE1=6
These parameters all have the default values.
7. Check the excitation field pattern as set in Step 7, by monitoring the TAP voltage.
For example, if the IPC’s CSAC mode was set and the Reader did not receive a valid message,
the TAP voltage has the following repetitive pattern: a carrier of 125.00 kHz modulated ON/
OFF with 610Hz for 60 ms, followed by no signal for 180 ms.
8. Save the excitation mode set in Step 7, by typing:
:CONFIG:STORE <Enter>
:RESET <Enter>
9. Check the parameter values set in Step 7 again.
10. Check the auto-diagnostic feature, by typing:
:DAR=Y <Enter>
:TEST:EXCITER k <Enter>
where k is the decimal address (1, 2, 3,...) of the Exciter that you want to test.
The response should be 00, followed by a number (between IP-2 and IP) of messages from the
Test Tag.

Configuring the Reader
Configuration and Operation 5-9
11. Turn off the excitation field again, by typing:
C<Enter>
12. Check the auto-diagnostic feature, by typing:
:TEST:EXCITER k <Enter>
The response should be C9.
13. Repeat Steps 1 to 13 (inclusive) for each Exciter that is connected to the Reader.
Configuring the Reader
The Reader’s receiving configuration is controlled by the following group of parameters:
• Data buffering/reporting configuration - Group D parameters
• Hardware configuration - Group H parameters
• Instrument generic configuration - Group I parameters
• Tag data reading configuration - Group R parameters
For more information on these parameters, see the RFID System S21 Reference Guide and the
RFID System S21 Technical Guide.
Note You can set these parameters for each particular application to optimize the functionality of the
Reader and the RFID System.

Warning Before starting this procedure, you have to enable the auto-report mode for the reader and set the
data report in ASCII format, by typing the following:
DAR=Y<Enter>
DHX=N<Enter>
To setup the Reader’s carrier threshold, do the following:
1. Switch off the excitation field, by typing:
C<Enter>
2. Set the Receiver’s signal-to-noise ratio, by typing:
RSS=10<Enter>
Note You can set other values for the RSS parameter. Lyngsoe recommends using a value between 10
and 20 for the RSS parameter.
3. If you are using Diversity, enable it by typing:
HAD=Y<Enter>
![](/img.php?id=293359&img=bg2e.png)
Setting Up the Carrier Threshold
5-10 Configuration and Operation
Ensure that both UHF antennas are connected. If you are not using Diversity, disable it by
typing:
HAD=N<Enter>
Ensure that only the right UHF antenna is selected (see the HAS parameter).
4. Check the noise level on the UHF channel, by typing:
HNL<Enter>
The HNL value should be between -107 to -95dBm.
If the HNL value is higher than -95dBm, check if there are unwanted transmissions on the
UHF channel (433.9 MHz). Pay special attention to Transponders or Exciters in close
proximity to the Reader; these can accidentally transmit data that can be received by the
Reader.
If the HNL value is lower than -105dBm, check its value without the UHF antennas attached.
The difference between these two readings must be greater than 3dB.

Setting Up the Carrier Threshold
Configuration and Operation 5-11
5. Set the carrier threshold, by typing:
S <Enter>
or
:CONFIG:THRESHOLD<Enter>
Note If the Reader resets itself, repeat the procedure from Step 1.
6. Monitor the DATA LED for at least 10 seconds. The LED must not flicker. If it does flicker
occasionally, increment the RSS parameter value by one. Go to Step
In installations where random interference is observed please contact Lyngso Industri A/S for
assistance.
IMPORTANT * For a normal setup, the sum of (HNL+RSS) must be less than - 85 dBm.
* If the noise level is higher than -95 dBm, disconnect the UHF antennas from the Reader, and
check whether the HNL value drops below -107 dBm. If this occurs, it means that there is
unwanted transmission on the UHF channel. To correct this situation, refer to Chapter 4, Setup
Guidelines in the RFID System S21 Technical Guide.
7. Place your Test Transponder PT21 1-2 m away from an Exciter that is controlled by the Reader
you are configuring. For more information about identification zones and the Test
Transponders, refer to Chapter 4, Setup Guidelines in the RFID System S21 Technical Guide.
8. Start the excitation field, by typing:
B<Enter>
9. Verify that the DATA LED is flickering, and check whether the Test Transponder’s messages
are displayed on the PC’s screen.
If data is not displayed, check the Reader’s parameter configuration, and follows the
troubleshooting instructions in Chapter 7, Troubleshooting.
If the number of displayed messages is below n=IP-2, check the carrier threshold and try to
adjust it again. Go to Step 1.
10. Remove the Test Transponder from the field and make sure that it is no longer transmitting by
ensuring that the DATA LED is not flickering.

Chapter 6
Programming and Testing the Transponder PT21
This chapter explains how to setup a programming site and gives the procedure for programming
the Transponders PT21. This chapter does not, however, explain how to choose parameter values.
Transmission parameters are defined and set in the programming software provided by Lyngso
Industri A/S. For more information parameter configurations for the Transponder PT21, see the
RFID System 21 Reference Guide.The PT21 Transponder is programmed using the Tag Qualifier
TQ21.
TQ21 - Tag Qualifier General Description
Tag Qualifier TQ21 can be used to test PT21/T96/T95 tags and to program tags PT21/T96. The
TQ21 is part of the RFID System S21 developed and marketed by Lyngsoe Industries.
This Chapter gives you a short presentation of the equipment TQ21 and basic information of how
to control it through its parameters.
A general overview of the commands and parameters used for TQ21 is presented in the Reference
Guide for RFID System S21 (or S95).
TQ21 Installation and Setup
To power up and interconnect the Tag Qualifier TQ21 with your computer see Figure 6-1 which
presents a typical installation.
WARNING Before you start the installation, check if the Power Supply provides the specified
output voltage - 12Vac or 12-16Vdc, and min. 0.3A; any polarity can be used for the dc output.
PC Software Configuration
The simplest way to control TQ21 is by using a Terminal Emulation program on the PC. The
general configuration procedure consists of:
• Open a Terminal Emulation program on your computer (Procomm, Hyper Terminal, etc.).
• Configure the computer's COM port to which the TQ21 is connected. The recommended PC
configuration for the COM port is: COM port - COM1; Data rate - 19200 bps; Data bits - 8
bits; Parity - none; Stop bits - 1; Flow control - none.
• From the PC send commands to TQ21 and observe the responses on the PC.
Other dedicated software can be used to control TQ21 as long as the correct commands are
provided for TQ21. Programming software can be purchased from Lyngso Industri A/S.
![](/img.php?id=293359&img=bg38.png)
TQ21 Connections
6-2
Setup the programming site, as shown in Figure 6.1:
Figure 1-4: P TQ21 Tag Qualifier Setup
TQ21 Connections
1. Connect the RS232 cable. Plug one end of the cable (DB9-Male) into the 9-pins connector on
the TQ21 (marked as RS232). Plug the other end of the cable (DB9-Female) into the serial port
(typical COM1) of your computer.
2. Connect the power adapter. Plug the power adapter output into the connector marked as
12Vac.
3. Turn on the TQ21 by connecting the power adapter into an available electrical outlet. The
POWER LED (green) goes ON, and the TQ21 performs a brief startup sequence, during
which the DATA LED (red) stays ON continuously for 5-7 seconds. After finishing the startup
sequence the DATA LED must turn OFF and the sign-on message Tag Qualifier TQ21
(c)Copyright Lyngsoe Industries Ltd. 2001 will be displayed on the PC.
4. TQ21 Sensitivity Threshold. Set the carrier threshold of TQ21 by sending the command S,
then save the setting by sending the commands:CONFIG:STORE and:RESET.
IMPORTANT NOTE
• The Power LED (green) lights to signalize that the power is connected to the TQ21.
• The DATA LED (red) lights continuously during the startup sequence and flashes when UHF
signals are received.
• The TQ21 cannot be used for testing if the Data LED randomly flashes after the startup
sequence is finished. In this case the sensitivity threshold must be set again and/or the source
of unwanted transmission eliminated.

New parameters and commands
6-3
The functionality of the Tag Qualifier TQ21 can be configured by parameters. These parameters
can be set from a PC connected through a standard serial interface RS232 to the TQ21. The
parameters and commands supported by TQ21 are quite similar with those listed in the Reference
Guide for System S21 with the following modifications.
New parameters and commands
Parameter:DFA
Type:Bit (Read/Write)
Range:Y/N
Default value:Y
Description:Enable (Y) or disable (N) the transmission of the flags using S21/S96 format. When
enabled, TQ21 transmits the received messages using the S21/S96 format for the flags field
(including the ReceivedID information). If disabled, TQ21 transmits the received messages using
S95 format for the flags field.
Parameter:DFI
Type:Bit (Read/Write)
Range:Y/N
Default value:Y
Description:Enable (Y) or disable (N) the frequency measurement for the UHF received signal.
When enabled, TQ21 transmits together with the received messages data about the carrier
frequency and frequency deviation of the received UHF signal (CF and DF). If disabled, TQ21
transmits the received messages using the format defined by DFA parameter.
Parameter:PME
Type:Bit (Read/Write)
Range:Y/N
Default value:Y
Description:Enable (Y) or disable (N) the transmission of the excitation signals using a Manchester
encoding format. When disabled, TQ21transmits the excitation signal using the S95 format. If
enabled, TQ21 ignores the status of the parameters REN and RTF (it operates with the default
values REN=N and RTF=Y).
Parameters and commands disabled
![](/img.php?id=293359&img=bg3a.png)
Firmware
6-4
Considering the S95 as a reference, the parameters PTA, PTT, PTV and RSM were disabled for
TQ21.
Firmware
For the command IVN, TQ21 will display its firmware version TQ21 v3.01.06. or a higher version.
Hardware configuration parameters
Several parameters are used to set (configure) the hardware and must not be changed. If the TQ21's
firmware is going to be updated, these parameters must be first written down and reprogrammed if
were accidentally erased by the upgrading process.
These parameters are: HA0, HA1, HA2, HA3, HA4, HA5, HA6, HA7, HA8, HA9, HA9, HAA,
HV0, HV1, ISC and ISN.
NOTE: Do not use the command:CONFIGURE:DEFAULT without saving first the values of all
hardware parameters. This command will set all parameters to their default values, this way erasing
the factory settings for the hardware parameters. If you erase by accident these hardware
parameters, TQ21 loses its calibration (capability to measure carrier and deviation frequencies) and
must be recalibrated again.
Software configuration parameters
For an optimum operation of TQ21 we recommend the following setting: DFI=Y, DHX=N,
DAR=Y, RCC=0, REC=Y.
Operation
General conditions In order to minimize the measurement errors the following conditions must be met before you can
start testing transponders:
• Power-up TQ21 for at least 15 minutes;
• Transponders to be kept at the room temperature (22 ±5 °C) for at least 2 hours.
• The Data LED to be steady Off (no flickering); see also sensitivity threshold, par.2.2.
• TQ21 to measure the "Reference Tags" with errors smaller than ±3 kHz.
Testing Tags Using TQ21 it's possible to test the following performances of a tag:
• Carrier frequency of the UHF transmission for modulation logic level "1". Field CF displays
the difference in kHz between the measured carrier frequency and 433.800MHz.
• Dynamic frequency deviation of the UHF transmission. Field DF displays the difference in
kHz between the measured carrier frequency for modulation logic "1" and logic "0".
• User data content; field UD.
• Number of transmitted messages. This number can be determined by counting the number of
![](/img.php?id=293359&img=bg3b.png)
Operation
6-5
received messages following an excitation.
• Flags status. Field FG gives you information regarding the battery status and the type of
excitation recognized by the tag.
Remember: To enable the frequency measurement function for the TQ21 parameter DFI must be
set as DFI=Y and the command B must be active (LF excitation field enabled).
The recommended procedure for testing a tag is the following:
• Check if the tag to be tested (EUT) was outside an LF excitation field for at least 10 s before
testing, and the command C is active for TQ21 (LF excitation disabled).
• Place the EUT inside the slot marked "Postal Tag" on the TQ21, with the battery side first
(battery to be at the bottom of the TQ21's slot).
• Send the command B.
• Check the content of the received messages on the PC. Dedicated software can be provided in
order to automatically process this information and to give just the "Pass" or "Fail" mark.
• Send the command C.
Remember: Tag PT21 must be keep at least 10 s outside the LF excitation field before it can accept
a new excitation.
Programming Tags TQ21 is capable of programming and querying tag PT21/T96.
The procedure of programming and querying is identical with the procedure used for tags T95
described in the User's Guide RFID S9. It includes the commands :TAG:MATCH (shortcut M),
:TAG:CLONE and :TAG:QUERY (shortcut Q), setting the "wanted" parameters (group W) and
querying the parameters (parameters from group T).
There are several particularities regarding the query/programming procedure.
• The tag programming function is performed without being necessary to change the status of
parameter DFI (works with DFI=Y and DFI=N).
• Tag PT21 must be kept at least 10 s outside the LF excitation field (command C active for at
least 10 s) between two consecutive commands M and/or Q.
• Tag must be inside the TQ21's slot for the whole duration of the query or programming
process; these processes are finished when the Data LED on the TQ21 stop flickering.

Troubleshooting
This chapter describes maintenance and troubleshooting procedures that you must follow when
using the RFID System 21. These procedures complete the troubleshooting information given in
Chapter 5, Configuration and Operation, for the initial system installation and configuration.
Preventive Maintenance
By using special commands, built-in Self Diagnostic circuits can check any part of the system and
report an error code, if necessary. Depending on the error code received, the service technician will
know the piece of hardware that is malfunctioning, and can immediately take corrective action to
remedy the situation.
All units have a warranty seal placed on their enclosures. Removal of this seal will void the
warranty.
General Guidelines
Below is a list of some assumptions and guidelines:
1. The chapter assumes that repairs for any electronic assemblies are not made on site. Unless
otherwise stated, if a specified condition cannot be met, the electronic assembly must replaced
and returned to the manufacturer for repairs.
2. For a complete technical description of the RFID System S21, refer to the RFID System S21
Technical Guide. For a detailed description of the commands and parameters used to configure

An improper carrier
threshold was set, or there is
an unwanted transmission on
the UHF channel.
1. Check whether the Reader is receiving
information that has been accidentally
transmitted from other Transponders in its
vicinity. If you eliminate the unwanted
transmission, the DATA LED will stop
flickering.
2. Check whether an Exciter’s Test Tag is
transmitting accidentally. Switch off the
power supply of all Exciters surrounding
the Reader and monitor the DATA LED. If
the DATA LED stops flickering, the
unwanted transmission originated in one
of the Exciters.
3. Run the procedure, S21 RFID System -
Final Test on page 5-15. Step 2 - Set up the
Carrier Threshold for the Reader.
4. If the Reader reports a channel noise level
below -95dBm, but you are still not
receiving the Transponders’ messages,
check the noise level reported by the
Reader with and without UHF antennas
connected. If the noise level is identical or
varies slightly (±1 dBm), replace the
Reader.
5. If the Reader reports a noise level (HNL)
above -95 dBm, the unwanted
transmission is on the UHF channel. For
procedures on eliminating the unwanted
transmission, refer to Chapter 4, Setup

Message Format
Transponder PT21 Messages B-1
Appendix B
Transponder PT21 Messages
Message Format
Each message has the following format
where:
Prmbl = 0.7 ms continue 1.
Sync = a string of 10 bits of “0101010101”; transmitted only if SM=Y.
Start = a string of 13 bits “0101010000111”; transmitted only if SM=Y.
SC = 2 bytes system code; transmitted only if TS=Y.
UD = user definable data; number of bytes is set by CC (1 to 32).
CRC = 2 bytes CRC; transmitted only if EC=Y.
Flag = 2 bytes message flags; transmitted only if TF=Y. It has 1 byte if HF=N and 2 bytes if
HF=Y.
Key = 1 byte message key; transmitted only if EN=Y.
PT21 Parameters The parameters that control the message transmission for PT21 are shown in the table below:
Total Transmission
Time
After a valid excitation, the PT21 transmits the initial number of messages defined by the IP
parameter, followed by an extra number of messages (up to the RC) for as long as the excitation
exists. Then it goes to sleep.
There is a random delay called InterMsgDelay that occurs between two consecutive messages.
This is implemented to ensure that the delay time does not repeat itself before 32 messages have
occurred.
Parameter Range Description
DR 3,4 Data rate; DR3 = 19.2 kbps, DR4= 38.4 kbps
EC Y/N Standard error check transmitted
EN Y/N Data encryption available
HF Y/N Flags in hexadecimal
ID 0...200 Initial delay
IP 1...200 Initial number of messages transmitted after a valid execution
LT Y/N Limit repeated transmissions
RC 0...255 Number of extra messages transmitted after IP during a continuous excitation
RS 0...255 Random seed
SD 1...220 Subsequent delay
SM Y/N Synchronous preamble transmitted
TF Y/N Transmit Flags
TS Y/N Transmit System Code

Message Format
B-2 Transponder PT21 Messages
The following is the method of evaluating the maximum transmission time for the PT21:
Number of bytes per message: TXBytes = SC + UD + CRC + Flag + Key
Number of bits per byte: BitsPerByte = 12 for DR4, and = 11 for DR3
Number of bits per message: TXBits = Sync + BitsPerByte*TXBytes
Bit duration: BitLen = 1/DR
Message length: MsLen = 0.0007 +TXBit*BitLen
Intermessage constant: InterMsgUnit = (UD + Flag)*0.0003066, for DR4;
= (UD + Flag)*0.0005657), for DR3
Intermessage delay: InterMsgDelay = [SD +RND(0…31)]*InterMsgUnit;
(RND - random value)
Maximum number of transmitted messages: NM = IP +RC; if LT = N
Total transmission time: TXTime = NM (MsLen +(NM-1) (InterMsgDelay)
The following tables present the maximum number of messages (NM) that can be transmitted in
five seconds, using different sets of parameters for the PT21.

Upgrading the Firmware
Reader Software Upgrade Procedure D-1
Appendix D
Reader Software Upgrade Procedure
This appendix describes the procedures for upgrading the Reader RD21 (P/N 600002) main
software using the serial interface RS232 or RS485. This software controls the functionality of the
Micro controller placed on the Receiver assembly REC21 (P/N 500007). This procedure
refers particularly to the upgrading process for software version 1.68.02.
Upgrading the Firmware
Upgrading the firmware involve the following steps:
1. Setting the Reader’s Address to 0
2. Saving parameters: HV0, HV1, ISC, ISN
3. Upgrading the firmware itself by using:
a) The RS232 interface
or
b) The RS485 interface: 4-wire communication line or 2-wire communication line
3. Restoring parameters: HV0, HV1, ISC, ISN
4. Setting the Reader’s Network Configuration
5. Final instructions
Setting the Reader’s
Address
To set the Reader’s address, do the following:
1. If the Reader already has an address, for example r, then set this address to 0 by typing the
following commands:
@r IAD=0<Enter>
@r :CONFIG:STORE<Enter>
@r :RESET<Enter>
For more information, refer to Storing the Reader’s Configuration on page 5-14.
2. Check whether the Reader’s address is 0, by typing the following command:
IVN<Enter>
The Reader must respond with its software version number. If not, repeat Step 1.
![](/img.php?id=293359&img=bg5a.png)
Upgrading the Firmware
D-2 Reader Software Upgrade Procedure
Saving Parameters Follow these steps:
1. Write down the values of the following parameters: HV0, HV1, ISC, ISN.
Note To determine a parameter’s value, for example, HV1, type the following command:
HV1<Enter>
For example, the Reader responds:
HV1=125
where 125 is the parameter value.
2. If the Reader was already configured, write down all parameters whose values differ from the
set default values.
For example, for an IPC installation, write down the values for the following parameters: DCI,
DRI, HTL, RCC, RSS.
Using the RS232
Interface
Follow these steps:
1. Connect your PC (COM port) to the Reader RD21 (RS232 interface) using a standard RS232
cable. For more information, refer to Setting Up the Reader/PC Connection on page 5-2.
2. Start the upgrading procedure by typing the following command:
:CONFIG:FIRMWARE:LOAD<Enter>
or type the following shortcut:
F<Enter>
3. Start XMODEM, send protocol on the PC, and then send the new firmware file. Lyngsoe
recommends having the new file on your hard drive and not on a floppy disk.
4. Wait until the transfer process is complete. If the 95 Series RFID System aborted the transfer
process, repeat Step 2.
5. If the downloading process was successful, wait for the Reader to reset - it takes about 5-7
seconds. For more information on the Reader’s power-up sequence, refer to Reader’s Power-
up Sequence on page 5-3. If the Reader did not reset properly and did not send a sign-on
message, then switch the Reader’s power supply Off and then On.
6. To verify whether the upgrade process was successful, type the following command:
IVN<Enter>
![](/img.php?id=293359&img=bg5b.png)
Upgrading the Firmware
Reader Software Upgrade Procedure D-3
The Reader must respond with the new firmware version number:
CRM95 V1.68.02, BUILT: 02/03/98 13:01:12
If not, repeat the procedure from Step 2.
7. If after completing Step 5, you still cannot communicate with the Reader, replace the Reader
with another unit and return the faulty one to Lyngsoe.
Using the RS485
Interface
4-wire
Communication
Line
Follow these steps:
1. Connect your PC (COM port) to a Converter RS232/RS485. Connect the 4-wire
communication line to the Converter (RS485 side). For more information on the
communication line connection to the Reader, refer to Connecting the RS485 Four-Wire
Communication Line on page 2-3 and Setting Up the Reader/PC Connection on page 5-2.
You can have a different assignment for the RS485 interface on the Converter side. Use the

Upgrading the Firmware
D-4 Reader Software Upgrade Procedure
Restoring Parameters Follow these steps:
1. Verify whether parameters were erased during the upgrade procedure, by typing:
ISC<Enter>
2. If the Reader responds with
ISC=0
then the original parameter values were erased and they were set to their default values.
3. Reset the parameters HV0, HV1, ISC, ISN to their original values prior to the upgrade
process. You recorded them during the Saving Parametersstep.
Note a) Firmware V1.68.02 ignores leading zeros for integers.
b) If the Reader was already configured on the site, you have to restore all application parameters
queried during the Saving Parametersstep, or restart the configuration process as described in
Chapter 5, Configuration and Operation.
3. Check the values of the new parameters that were introduced by this software version. For
example, For an IPC installation, the following parameters must have the default values as
follows:
HCC=8, HCS=7, HE0=18, HE1=6, RCS=Y, RES=Y, SFC=N
Setting the Reader’s
Network Configuration
To set the Reader’s network configuration, do the following:
1. Set the Reader’s address to it initial value (see step 1 in Setting the Reader’s Address): by
typing:
IAD=r<Enter>
2. Store the Reader’s parameters, by typing:
:CONFIG:STORE<Enter>
3. Reset the Reader, by typing:
:RESET<Enter>
4. Verify that the Reader is functioning properly, by typing:
@r IVN<Enter>
where r is the Reader’s address. The Reader must respond with its software version number.
5. Verify that the parameters set in the following sections are correct:
• Steps 2 and 3 from the section, Restoring Parameters above.
• Step 1 in this section.

Reader Software Upgrade Procedure D-5
Final Instructions 1. You must repeat this procedure for each Reader RD21 that is installed on the site.
2. Lyngsoe recommends using the RS232 or RS485 4-wire communication line to upgrade the
Reader’s software (these are more reliable communication links).
3. For more information on the Reader’s RD21 configuration, see Chapter 5, Configuration and
Operation.
