Chapter 1

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.

RFID Specific Terms

Transponder Transponders are devices that receive an excitation signal, and respond by transmitting back a

message.

Excitation Signal The excitation signal is a form of electromagnetic energy that is used to wake up the tag.

Response 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.

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. .

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.

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/PT23 carrying the identification data

• Exciters EX21 to generate an electromagnetic (LF) field that excites the Transponder PT21/

PT23

• Readers RD21 to receive data transmitted by the Transponder PT21/PT23(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

Communication Links There are several communication links between the components of the RFID System S21.

• 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. System Code

Reader Address When a Reader is part of a network, it must have a unique address.

Real Time Clock The Reader RD21 has an on board Real Time Clock.

Reader Data Handling Data that is captured from the Transponder is stored in an internal buffer.

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.

Reader Reset There are two main ways to reset the Reader:

• Hardware reset

RFID System S21 Configuration Principles

1-4 Introduction

• Software reset.

For the hardware reset, switch off the Reader’s power supply for a least 5 seconds. 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 system 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 6.10.06 or higher.

For more information regarding communications and upgrading firmware - see Appendix D.

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.

Configuration and Operation

This chapter explains how to set-up and configure a RFID System S21. The IPC implementation is

a practical example of the RFID System S21 configuration. For more information about the RFID

System S21 configuration, refer to the RFID System S21 Technical Guide.

Before You Begin

Before starting the RFID System S21 configuration, do the following:

1. Check whether all equipment is correctly installed and interconnected according to the

requirements stated in Chapter 2, Reader RD21 Installation and Connections and Chapter 3,

Exciter EX21 Installation and Connections in this guide.

2. Check if each Reader and Exciter has a unique address according the approved documentation

describing the RFID System configuration (see the specific Site Survey documentation).

3. Familiarize yourself with the instructions format described in the RFID System S21 Reference

Guide, and the system’s functionality described in the RFID System S21 Technical Guide.

4. Refer to the section, RFID System S21 Configuration Principles on page 1-3, for some general

explanations on configuring the RFID System S21. Pay special attention that the jumpers on

the CTL21 and LFA21 are set for S21 operation.

General Procedure Rules

Each Reader and Exciter in the RFID System must be configured individually.

Lyngsoe recommends that you follow the general rules listed below:

1. Configure each Reading Point, one by one. Each Reading Point is defined and controlled by a

reader. Configuration of the Reader and interconnected Exciters is accomplished by

connecting a PC to the serial communication link.

2. Follow the step-by-step instructions described in this chapter.

3. If you do not obtain the expected results, refer to Chapter 7, Troubleshooting.

Setting Up the Reader/PC Connection

5-2 Configuration and Operation

Setting Up the Reader/PC Connection

To connect the Reader to a PC, do the following:

1. Use the RS232 or RS485 communication line to connect the Reader to the PC. For more

information on these communication lines, see Connecting the RS232 Communication Line,

and Connecting the RS485 Four-Wire Communication Line in Chapter 2.

For the initial set-up, Lyngsoe recommends using the RS232 connection with a local, mobile PC

(Laptop), as shown in Figure 5-1 below.

Figure 5-1: Connecting the Reader to a PC/Laptop

2. Run a terminal emulation program on the PC, such as, Hyper Terminal in MS Windows. The

recommended configuration for the PC’s port is:

• Data rate - 19200 bps

• Data bits - 8 bits

• Parity - none

• Stop bits - 1

• Flow control - none

Configuration and Operation 5-3

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

each other. If you modify the Reader’s parameters, you must save them before leaving the

learning mode. For more information on this procedure, see Storing the Reader’s

Configuration on page 5-14.

6. Press the RESET button again to exit from the learning mode.

7. The DATA LED will stop flashing.

Notes 1. The serial communication configuration for an IPC application has the default values for the

group of S parameters. For more information on the group of S parameters, refer to the RFID

System S21 Reference Guide.

2. If the noise and interference level on the UHF channel exceeds the carrier threshold or a

Transponder is transmitting information, the DATA LED will start flashing at a faster rate.

Resetting the Reader

There are 2 ways to reset the Reader (see Figure 5-1):

• By resetting the hardware

• By resetting the software

For a hardware reset, switch off the Reader’s power supply for a least 5 seconds.

For a software reset, you can:

1. Press the RESET button twice.

2. Type the following command at the prompt:

:RESET <Enter>

Checking the Reader’s Basic Parameters

To check basic parameters of the Reader, do the following:

1. Check the software version number by typing:

IVN <Enter>

The response should be:

IVN=REC21 V5.00.01., BUILT: __/__/__ __:__:__.

Note You can upgrade the Reader software, if necessary. For more information on upgrading the

software, refer to Appendix D, Reader Software Upgrade Procedure.

Checking the Reader’s Basic Parameters

Configuration and Operation 5-5

2. Check the System Code (SC), by typing:

ISC <Enter>

The response should be:

ISC= [your SC]

If the displayed System Code is not identical with the application system code number, replace

the Reader and report the problem to Lyngsoe.

3. Check the Receiver’s Serial Number (SN), by typing:

ISN [your SN]<Enter>

If the displayed serial number is not equal to the serial number on the Receiver’s REC21

board, set it to the correct value. For example, if the SN is U123456, then type:

ISN=U123456<Enter>

4. Store the new SN and/or SC parameter values, by typing:

:CONFIG:STORE <Enter>

:RESET <Enter>

5. Check if the IVN, ISC, and ISN parameters have correct values, by repeating Steps 1 to 3.

6. Switch off the LF field, by typing:

C<Enter>

Setting Up the Exciter’s Address

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]

Note Figure 5.2 displays the S1 setting for address 1.

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.

3. For checking of LF signal integrity refer to the field application notes provided with the

equipment or 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.

Setting Up the Carrier Threshold

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>

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>

: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/PT23 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.

Setting Up the Exciter’s Test-Tag

rr is the Reader’s address. If Reader’s address is 1, rr = 01.

kk is the Exciter’s address. If the Exciter’s address is 1, kk = 01.

2. Turn off the LF field, by typing:

C<Enter>

3. Program the Exciter Test-Tag, by typing:

:TAG:MATCH:EXCITER k<Enter>

where k is the address of the Exciter you want to program.

If the response is not 00, the Exciter is not programmed. Repeat this command several times,

waiting at least 3 seconds between retries.

Note If you cannot program the Test Tag, see Chapter 7, Troubleshooting.

4. Turn on the LF field, by typing:

B<Enter>

5. Test the Exciter Test-Tag, by typing:

:TEST:EXCITER k<Enter>

where k is the address of the Exciter you want to test. The correct response is 00, followed by

Chapter 6

Programming and Testing the Transponder PT21/PT23

This chapter explains how to setup a programming site and gives the procedure for programming

the Transponders PT21/PT23. 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/

PT23, see the RFID System 21 Reference Guide.The PT21/PT23 Transponder is programmed using

the Tag Qualifier TQ21.

TQ21 - Tag Qualifier General Description

Tag Qualifier TQ21 can be used to test PT21/PT23/T96/T95 tags and to program tags PT21/PT23/

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.

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.

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

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

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/PT23 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/PT23/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/PT23 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

or to control the 95 Series RFID System, refer to the RFID System S21 Reference Guide.

3. Information regarding the RFID System S21 configuration and operation is described in

Chapter 5, Configuration and Operation.

4. The locations of the DATA LED, the POWER LED, and the RESET button are shown in

Figure 5-1.

5. All the reference to commands are made assuming that the Reader’s address is 0.

7-2 Troubleshooting

The following table describes several possible failures for the 95 Series RFID System, and the

troubleshooting steps to correct them.

Problem Symptom Probable Cause Solution

No communication with

a Reader.

Reader does not

respond to any

command.

1. Reader has an incorrect

address.

2. Faulty communication line

between the Reader and

PC.

1. Check whether the Reader responds to

commands using different addresses, by

typing the following: @1 IVN<Enter>,

@2 IVN<Enter>, @3 IVN<Enter>. When

a correct address is sent, the Reader will

respond with its version number.

2. If, by using a specific address, you are

able to communicate with Reader, use this

address or change the address to another

value.

3. If after checking all possible addresses (up

to 31), you still cannot communicate with

the Reader, check Probable Cause 2.

1. Open the Reader’s enclosure and connect

the PC directly to the Reader using the

RS-232 communication line. See

Connecting the RS232 Communication

Line on page 2-2.

2. Switch off the Reader’s power supply for

at least 5 seconds, then perform the steps

in the Reader’s Power-up Sequence on

page 5-3.

3. If the Reader performs the power-on test

successfully, press the RESET button

once. Check whether the DATA LED

starts flashing at the rate of 2 Hz.

4. Press the RESET button again. Check

whether the DATA LED stops flashing.

5. Check whether the Reader is responding

to local commands by typing: @r IVN,

and pressing <Enter>, where r is the

Reader’s address. The Reader must

respond with its version number.

configuration parameters.

6. If you are able to communicate with the

Reader from the local PC, check the

integrity of the communication line

between the Reader and the PC.

7. After fixing the communication line’s

integrity, reconfigure the 95 Series RFID

System and check whether the Reader can

communicate with the PC.

8. If you cannot communicate with the

Reader (Step 5), check Probable Cause 3.

1. Open the Reader’s enclosure and connect

the PC directly to the Reader using the

RS-232 communication line. See

Connecting the RS232 Communication

Line on page 2-2.

2. Switch off the Reader’s power supply for

at least 5 seconds, then perform the steps

in the Reader’s Power-up Sequence on

page 5-3.

3. If the power-on test is successful, the

DATA LED should start flashing

continuously at the rate of 1.4 Hz.

4. Check the System Code number by

typing: ISC, and pressing <Enter>. If the

Reader responds with ISC = 0, setup

the Reader’s System code again by

typing: ISC = your SC, and pressing

<Enter>.

5. If the Reader restored one of its

parameters to the default value, all other

parameters are also reset to their default

values. Check and reset all the

application- specific parameters to their

original values.

6. Check the HV0 and HV1 parameter

values. If these parameters have default

values 73 and 105 respectively, you must

set them again using the correct values

from Lyngsoe’s database.

General Guidelines

7-4 Troubleshooting

7. Store the Reader’s configuration by

following the steps in the section, Storing

the Reader’s Configuration on page 5-14.

Note

The HV0 and HV1 parameters are set at the

factory during the adjusting procedure and

recorded for each Reader. If you know the

Reader’s serial number, Lyngsoe can supply

you with the values.

Reader does not record the

Transponder’s messages.

After the power-on

test is finished, the

sign-on message is

displayed on the PC,

but the DATA LED is

flashing continuously

at a random rate.

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

Guidelines in the 95 Series RFID System

Technical Guide.

but the DATA LED is

not flashing when a

Transponder is

activated.

The configurations of the

Transponder and the Reader

do not match.

The carrier threshold value is

too high.

1. Using a Test Transponder TST95 that has

been programmed for your application,

test the Reader’s receiving capability.

2. If you can receive transmitted messages

from the TST95, the Transponders are

either not correctly configured for your

application, or they are out of

specifications. Reprogram the

Transponders and check whether the

Reader can receive messages.

3. If you cannot receive transmitted

messages from the TST95, the Reader has

an incorrect configuration. Go to Steps 4

and 5.

4. Check whether the DAR parameter and

the Group R parameters are set according

to the application’s specifications.

5. With this new set of parameters, check

whether the Reader can receive

transmitted messages from the TST95. If

the Reader can receive the messages, save

its configuration, by typing the following

commands and pressing <Enter> after

each command: :CONFIG:STORE,

:RESET.

1. Run the procedure, S21 RFID System -

4. If the value of (HNL + RSS) is higher

than -85dBm, there is either an unwanted

transmission on the UHF channel, or the

value of the RSS parameter is too high.

The value for the RSS parameter must

be between 10 and 20.

5. Check whether there are Transponders or

an Exciter’s Test Tag in the immediate

vicinity that transmit messages

accidentally.

6. Run the procedure, Setting Up the Carrier

Threshold again, and monitor the value

for the HNL parameter after each setup.

7. For procedures on eliminating the

there is random interference

on the UHF channel.

1. Run the procedure, S21 RFID System -

Final Test on page 5-15. Step 2 - Set up the

Carrier Threshold for the Reader.

2. If you observe a random variation of noise

and interference on the UHF channel,

either increase the value of the RSS

parameter, or set the HTL parameter to a

higher value than the one that was

automatically set by the Reader.

3. If the receiving zone is too small after you

set a higher carrier threshold, follow the
