Transponder Identification System

Introduction 1-1

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. 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

Systems, 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. The presence of the seconds field in

the time stamp is optional and is controlled by the DTS 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.

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 a 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.

2-4 Reader RD21 Installation and Connections

Caution Before installing the RFID System, label the 4 wires of the RS485 line as A, B, Z and Y. Keep this

naming convention for all connections made on this RS485 communication line.

4. Set the termination load for the RS485 communication line. The ends of a multidrop network

line can be easily identified, because only one RS485 cable is connected to that equipment. To

connect a 120 ohm terminating load, place the jumper P1 between pins 1-2 of J1(load

position). If the equipment is not at the end of the RS485 communication line (two RS485

cables coming in), place the jumper P1 between pins 2-3 of J1 (Open position).

5. To select the RS485 interface, place the jumper P3 between pins 2-3 of J3.

6. Plug terminal blocks TB4 and TB6 into connectors TB3 and TB5 respectively.

Connecting the Exciter Communication Line

Two separate RS485 two-wire interfaces are used to communicate between Readers and Exciters.

For more information regarding the communication link, see the RFID System S21 Technical

Guide. The RS485 connectors and jumpers for these lines are located on the Controller Board

CTL21. The CTL21 is the top board of the Reader Module Assembly.

Notes 1. For the RS485 line, use specially designed cables only, such as, BELDEN type 9842, or

similar.

2. To simplify the RS485 multidrop-type connection, the two RS485 connectors, TB4 and TB6,

are wired in parallel on the MBD21. Connect the incoming RS485 cable to one connector and

the out going RS485 cable to the other.

To connect Exciter communication lines to the Reader, refer to Figure 2-3 and:

Complete the following steps:

1. Unplug terminal blocks TB2 and TB4 from connectors TB1 and TB3 respectively.

2. Run the RS485 incoming and out going cables through the cable grips into the Reader’s

enclosure.

3. Connect the four-wire communication line to the corresponding pins A1, B1, A2, and B2 on

terminal block TB2 (or TB4). Connect the cable shield to the pin marked GP on terminal block

TB2 (or TB4).

Reader RD21 Installation and Connections 2-5

Caution Before installing the RFID System, label the two wires of one line of RS-485 as A1 and B1, and the

other two wires of RS485 as A2 and B2. Keep this naming convention for all connections made on

this communication line.

4. Set the termination load RS485 communication line for each two-wire line. The ends of a

multidrop network line can be easily identified, because only one communication cable is

connected to that equipment. To connect a 100 ohm terminating load on each separate RS485

line, place jumper P1 between pins 1-2 of J1(Load position), and jumper P2 between pins 1-2

of J2 (Load position). If the equipment is not at the end of the RS485 communication line (two

RS485 cables coming in), place jumpers P1 between pins 2-3 of J1, and P2 between pins 2-3 of

J2 respectively (open position).

5. Plug terminal blocks TB2 and TB4 into connectors TB1 and TB3 respectively.

Connecting the Power Supply

The Reader RD21 requires a 12Vac or 13 to 16Vdc power source, and a maximum current of 0.3A.

For more information on the Reader, see Appendix A, Specifications. The power supply connector

is located on the Motherboard MBD21. The MBD21 is the bottom board of the Reader Module

Assembly (P/N 500020).

Notes 1. To connect the power supply, use electrical wire gauge 16 AWG (minimum).

2. The main ground connection of the Reader is on the power supply connector. It is indicated by

the ground symbol. Use an electrical wire with at least gauge 16AWG for the main ground

connection.

3. To power up Reader RD21 we recommend using Power Supply, model TRM95 120V or

TRM95 230V, as required by the local AC power line voltage.

4. Two different installation types exist: one Reader per power supply and multiple Readers per

power supply.

Mechanical Assembling

3-2 Exciter EX21 Installation and Connections

Mechanical Assembling

To assemble the Exciter EX21, refer to EX21 General Assembly drawing 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 EX21 General Assembly drawing.

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.

2 wires on the RS485_SGN line A2 and B2. Keep this naming / wire colour convention for all

connections made on these RS-485 communication lines.

4. Set the terminating load for the each RS485 communication line. The ends of a multidrop-

network line could be easily identified, because only one cable is connected to the

equipment.To connect a 100 ohm terminating load to the RS485_CMD line, place the jumper

P2 between pins 1-2 of J4. When connecting any other equipment to this RS485

communication line, place the jumper P2 between pins 2-3 of J4.

To connect a 100 ohm terminating load to the RS485_SGN line, place the jumper P3 between

pins 1-2 of J5 (Load position). When connecting any other equipment to this RS-485

communication line, place the jumper P3 between pins 2-3 of J5 (Open position).

5. Plug terminal blocks TB4 and TB6 into connectors TB3 and TB5 respectively.

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, the connection with a local, mobile PC (Laptop) can be realized using an

RS232 interface as shown in Figure 5-1 below.

Figure 5-1: Connecting the Reader to a PC/Laptop using RS232 interface.

Alternatively, the PC/Laptop can be connected to Reader’s RS485 interface.In this case, the

specially designed RS485 Tester and Connecting Board CBD16 (both products of Lyngsoe

Systems) can be used. The usage of a third party RS485 converter is not recommended due to

different technical standards used by different manufacturers. The set-up is shown in Figure 5-2

Reader’s Power-up Sequence

5-4 Configuration and Operation

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 POWER LED is on

(See Figure 5-1).

3. Check whether the Reader performs the following power-on test sequence: the 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 Systems Ltd 2003.

Notes 1. If the Reader does not have assigned a System Code identification number (SC) or one or more

manufacturing calibration parameters are missing, then the DATA LED will flash On and Off

at a rate of 1.4 Hz. To set the calibration parameters, return the Reader for re-calibration. 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

Resetting the Reader

Configuration and Operation 5-5

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

Configuration on page 5-17.

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 V_.__.__., 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

5-6 Configuration and Operation

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<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

Configuration and Operation 5-7

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 5-3.

Figure 5-3: 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 5-3 displays the S1 setting for address 1.

LF Transmitter Output

5-8 Configuration and Operation

LF Transmitter Output

The type of the generated LF excitation signals depends on the 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 signal is defined in the Appendix C. To properly

set the transmitter output for “System 95” please refer to the “95 Series RFID Systems User’s

Guide”.

To set the LF signal for “System S21”, refer to Figure 5-4 below, and do the following:

Figure 5-4: LF Signal Measurement

1. Connect the power to the Exciter. If there are additional Exciters connected to the same

Reader, make sure that their power is off.

2. To ensure proper setup, send the following commands:

4. Set the wanted C9 threshold voltage to the value required by application (40V recommended

for most cases):

NVT=xx<Enter>,xx - is the value in Volts

5. To start the Exciter self calibration process send

:CONFIG:EXCITER n<Enter>

Wait about 30 seconds for the process to finish. If the returned error code is not 00, refer to

RFID System S21 Reference Guide for the command operation and error codes description.

6. Check the auto-diagnostic feature, by typing:

:DATA:PURGE<Enter>

:TEST:EXCITER n<Enter>

where n is the decimal address (1, 2, 3,...) of the Exciter that you want to test.

The response should be 00, meaning that the TAP voltage is higher than C9 threshold, and the

Reader should contain in the buffer a message from the Test Tag.

7. Check the excitation field pattern by monitoring the TAP voltage with the Oscilloscope. Make

sure that the TAP voltage is set to the correct value.

8. Turn off the excitation field, by typing:

C<Enter>

The TAP voltage amplitude should become zero.

9. Turn on the LF field again, by typing:

B <Enter>

The TAP voltage signal should have the same value and pattern as measured in Step 7.

10. Repeat Steps 1 to 9 (inclusive) for each Exciter that is connected to the Reader.

11. Power up all Exciters connected to the Reader.

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. To do that, 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. As a general

guideline, the minimum amplitude of VTAP due to unwanted modulation should be more than two

thirds or 67% of the application required Vpp value.

Configuring the Reader

5-10 Configuration and Operation

To check the Exciter’s current settings including its serial number, do the following:

POWER:QUERY:EXCITER n<Enter>

ESN<Enter>

EVT<Enter> - returns the value of threshold in Volts

EVA<Enter> - returns the TAP signal value in Volts

Note The value of Group E parameters is valid only after a successful :POWER:QUERY:EXCITER

command. Note that the default value of these parameters (after the Reader reset) is set to

unrealistic value so that the user does not think that these are actual Exciter settings (refer to RFID

System S21 Reference Guide).

In orger to set the Exciter TAP voltage, instead of using the :CONFIG:EXCITER n command as

described above, the user can iteratively do the following:

NVX=some value<Enter>

POWER:MATCH:EXCITER n<Enter>

POWER:QUERY:EXCITER n<Enter>

EVA<Enter> - returns the TAPsignal value in Volts

The LF field strength in the Exciter is set by a digital potentiometer. The NVX parameter

directly sets its wiper position. This position will result in a certain LF field strength specific to

this particular Exciter. The actual field strength can then be checked by querying the EVA

parameter. This procedure can be useful , for example, if the user wants to quickly set the

Exciter to generate the maximum or minimum level of field.

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>

Setting Up the Carrier Threshold

Configuration and Operation 5-11

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>

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.

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 5.

Setting Up the Exciter’s Test-Tag

5-12 Configuration and Operation

In installations where random interference is observed please contact Lyngsoe Systems 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 follow the

troubleshooting instructions in Chapter 7, Troubleshooting.

If the number of displayed messages is below n=IP+RC-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.

11. Set the DAR and DHX parameters to their original values. To store the settings, type

:CONFIG:STORE<Enter>

Setting Up the Exciter’s Test-Tag

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:

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

a number of messages between IP-2 and IP. If less messages are received, verify whether the

UHF channel is jammed or replace the LFA21 board.

Note If you do not see the expected number of messages on your PC, (13-15 messages for an IPC site),

see Chapter 7, Troubleshooting and check the following parameters:

DAR=Y; DCI=0, DRI=0

6. Repeat Steps 1 to 5 for each Exciter that is connected to the Reader.

Setting Up the Real Time Clock

The Real Time Clock operation is controlled by the following commands/parameters: IUT, IUM,

DTS. For more information on setting up the Real Time Clock, refer to the RFID System S21

Reference Guide. You can set the Reader’s date and time by using the IUT parameter.

Configuring Reader Motion Sensor Driven Mode of Operation

5-14 Configuration and Operation

Example For an IPC application, you should set the IUT parameter to GMT time. To set it, type:

IUT=YYMMDDhhmmssZ<Enter>

where YYMMDDhhmmss is the year, month, day, hour, minute and second respectively.

Note: The parameter DTS must be set to “Y” in order for the reader to report time in seconds.

The parameter IUM must be set to “Y” in order for the Reader to generate and store a special

message each time the RTC is set by the IUT command.

Configuring Reader Motion Sensor Driven Mode of Operation

In this mode, the MS is connected to the Mother Board MBD21 as shown in Figure 5-5. One MS

controlls all Exciters connected to the Reader.

Figure 5-5: MS connection to the Reader MBD21.

The following parameters define the Reader MS Driven Mode of operation:

ROD, IOF, IOM, ROE, DNT, HMS, DIS, HOA, HOS.

For detailed explanations refer to the RFID System S21 Reference Guide.

Example ROD=Y<Enter> - enables MS Driven Mode;

IOF=Y<Enter> - LF field and data buffering is turned ON/OFF by MS;

Configuring Exciter Motion Sensor Driven Mode of Operation

In this mode, each exciter is controlled individually by its own MS. One or two Motion Sensors can

be connected to the Exciter LFA21. Figure 5-6 shows the connection of one MS. Similarly, the

second MS can be connected to the MS2 input. When two MSs control one Exciter, either one of

them can turn the LF field on.

Note Motion Sensor contacts must be normally closed when there is no motion. Unused MS input must

be shorted to the Ground by means of wire in the connector.

Figure 5-6: MS connection to the Exciter LFA21.

The following commands/parameters define the Exciter MS Driven Mode of operation:

:ENABLE:MS:EXCITER n, :DISABLE:MS:EXCITER n, :TEST:MS:EXCITER n, EMS.

For detailed explanations refer to the RFID System S21 Reference Guide.

Configuring the Reader’s Application Parameters

5-16 Configuration and Operation

To remotely test the MS functionality do the following:

Send the :TEST:MS:EXCITER n command. Wait for a period of time. Send the

:TEST:MS:EXCITER n again. Check the value of the EMS parameter. This value indicates the

number of times the MS turned active since the last time the :TEST:MS:EXCITER n command was

sent. If you know that there was some activity around the gate but the EMS=0, this means that the

MS is defective.

Note Execution of the :TEST:EXCITER n command is not affected by the motion sensor status. If MS is

not active, the LF field is forced ON for a brief period of time enough to finish the self test

procedure.

Configuring the Reader’s Application Parameters

You can configure the Reader’s application parameters by setting the appropriate values for the

parameters in the following groups:

• Data buffering/reporting configuration (D)

• Hardware configuration (H)

• Instrument generic configuration (I)

• Tag data reading/excitation configuration (R)

• Serial communication configuration (S)

For detailed explanations refer to the RFID System S21 Reference Guide.

Example For example, for an IPC application, do the following:

1. Set the Flags reporting format to S95:

DFA=N <Enter>

2. Enable the Gate ID filtration on the Reader, by typing:

IFA=Y <Enter>

3. Set the data filtration on the Reader, by typing:

DCI=10 <Enter>

DRI=30 <Enter>

4. Set the reported data format as ANS.1 format, by typing:

DHX=Y <Enter>

5. Set the Tag data character count, by typing:

RCC=5 <Enter>

6. Use the default values for all the other parameters.

S21 RFID System - Final Test

IMPORTANT * These tests must be done after all Readers and the Main PC are connected to the network

according to the site documentation.

* The PC must be connected using an appropriate serial communication interface.

* To communicate with the Reader, either use a terminal emulation program, such as Hyper

Terminal or Procomm in MS Windows applications, or the dedicated service module of the

application software running on the Main PC.

* All commands to the Reader must include the address field @r where r is the Reader’s address

(an integer followed by a blank).

You must repeat the following procedure for each Reader that is connected to the Main PC.

For the final test, do the following:

1. Verify that the Reader is communicating with the Main PC, by typing:

@r IVN <Enter>

where r is the Reader’s address. The Reader must respond with the software’s version number.

2. Set up the Carrier Threshold for the Reader as follows:

a) Switch on the excitation field, by typing:

@r B <Enter>

b) Check the noise level, by typing:

@r HNL<Enter>

If there is no unwanted transmission on the UHF channel, the Reader must respond with a

value lower than -95dBm for the HNL parameter. If not, refer to Setting Up the Carrier

Threshold on page 5-10.

c) Check and record the value for the existing Reader’s Carrier Threshold level, by typing:

level again, by typing:

@r S<Enter>

@r :CONFIG:THRESHOLD<Enter>

The Carrier Threshold level setting is correct if the new HNL level displayed is smaller than or

equal to the level displayed in Step c. If not, check for unwanted transmission on the UHF

channel. You should also refer to Chapter 4, Setup Guidelines in the RFID System S21

Technical Guide.

3. Verify that an Exciter that is controlled by a Reader communicates with the Main PC:

a) Delete all Tag records from the Reader’s buffer, by typing:

@r :DATA:PURGE<Enter>

b) Confirm that the Reader’s buffer is empty, by typing:

@r D<Enter>

@r :DATA:REPORT<Enter>

The Reader must report a Null value.

Note For an IPC application, the data structure conforms to the ANS.1 standard. If the Reader’s buffer is

empty, the Reader sends a Null value of $0500. In ASCII format, the Null value is {}.

c) Switch on the LF field, by typing:

@r B<Enter>

d) Send a Test Exciter command, by typing:

@r :TEST:EXCITER k<Enter>

where r is the Reader’s address and k is the Exciter’s address. The correct Exciter’s response is

00.

e) Check the received messages, by typing:

@r D<Enter>

@r :DATA:REPORT<Enter>

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 Lyngsoe

Systems 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 Systems.

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 14-16Vdc, 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 Lyngsoe Systems A/S.

TQ21 Connections

6-2

Setup the programming site, as shown in Figure 6.1:

Figure 1-7: 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 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 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.

Parameters and commands disabled

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

6-4

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, 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

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

Operation

6-5

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 tags PT21/T96.

The procedure of programming and querying is identical with the procedure used for tags T95

described in the User's Guide RFID S95. 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.

• 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 Q and/or M.

• 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.

Chapter 7

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 RFID System S21, 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 references to commands are made assuming that the Reader’s address is 0.

The following table describes several possible failures for the RFID System S21, and the

troubleshooting steps to correct them.

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.

1.1.2. Faulty

PC.

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 5-4.

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.

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

main PC.

7. After fixing the communication line’s integrity,

reconfigure the RFID System S21 and check

whether the Reader can communicate with the PC.

8. If you cannot communicate with the Reader (Step

5), check Probable Cause 3.

2. Push once the RESET button on the Motherboard.

The DATA LED should start blinking indicating the

“Learning Mode”.

3. Type several random characters on the PC

keyboard. The Reader should recognize the serial

communication parameters, match them and display

them on screen, f.e. 19200, None, 8, 1.

4. Set the relevant Reader parameters accordingly

(refer to the RFID System S21 Reference Guide).

5. Send :CONFIG:STORE.

6. Push the RESET button again to exit “Learning

displayed on the

PC, but the

DATA LED is

flashing

continuously at a

random rate.

2.1.1. 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 is being 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

(faulty board). 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 5-18. 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, there is unwanted transmission on the UHF

channel from an external jammer. For procedures on

eliminating the unwanted transmission, refer to

2.3.1. The carrier threshold

value is too high. 1. Check the ambient noise level (HNL parameter).

The noise shoud not be higher than -95dBm. Type

HNL several times to ensure that ambient noise

does not change over time. If the noise is higher

than -95dBm, it means that there is a jammer. In that

case, go to Step 7.

2. Make sure that RSS value is in between 10 and 20

reported by the Reader with and without UHF

antennas connected. If the noise level is identical or

varies slightly (±1 dBm), replace the Reader.

7. Investigate from where the unwanted transmission

is coming. It could be Exciter Tag or some other

Tags in close proximity or an external transmitter.

8. If the unwanted transmission is impossible to

eliminate, refer to Chapter 4, Setup Guidelines in

the RFID System S21 Technical Guide.

3. Reader does not

record all transmitted

messages.

3.1. Reader does

not record all

transmitted

messages by the

Transponder.

3.1.1. The receiving zone

is too small because of

either a high carrier

threshold, or there is

random interference on

the UHF channel.

1. Run the procedure, S21 RFID System - Final Test on

page 5-18. 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 setup guidelines

recommended in Chapter 4, Setup Guidelines in the

RFID System S21 Technical Guide.

Note

A UHF channel is subject to random noise and

interference. The Reader disregards the messages with

data errors. For an optimal channel, free of interference

and industrial noise, the Reader must be able to receive

all messages transmitted by a single Transponder

placed in its reading range. When using multiple

Transponders, some messages are lost due to the

inherent collision between them.

4. Time-out error. At

the command

:TEST:EXCITER k,

the response is 00,

but the Main PC does

not receive a correct

message from the

Test Tag of the

Exciter k after a

predetermined period

of time.

4.1. DATA LED

is flickering, the

Reader’s Tag

Record Buffer

contains

messages from

the Test Tag.

4.1.1. User data in the Test

tag was incorrectly

programmed.

1. Query the Test Tag programming parameters using

:TAG:QUERY:EXCITER k.

2. Check the user data (TUD).

3. Correct the user data (WUD).

4. Reprogram the Test Tag using the command

:TAG:MATCH:EXCITER k.

4.2. DATA LED

is flickering, but

the Reader’s Tag

Record Buffer is

empty.

4.2.1. Test tag was

incorrectly programmed. 1. Query the Test Tag programming parameters using

:TAG:QUERY:EXCITER k.

2. Check the value of all group T parameters.

3. Correct the values using the group W parameters.

4. Reprogram the Test Tag using the command

:TAG:MATCH:EXCITER k.

4.3. DATA LED

is not flickering

4.3.1. Exciter’s Test Tag is

placed beyond the limits

of the receiving zone, or

the noise level is too high,

or the Test Tag is out of

specifications.

1. Run the procedure, S21 RFID System - Final Test on

page 5-18. Step 2 - Set up the Carrier Threshold for

the Reader.

2. Check the RF level of the messages received from

the Test Tag; it must be higher than

(RSS+HNL+3)dBm, that means 3dB above the

carrier threshold value.

Note

The Reader reports the RF level of the received

message only if the parameter DLI=Y.

3. If the RF level of the Test Tag’s received messages

is lower than -85dBm, either reposition the

Reader or Exciter, or use a higher gain UHF antenna

for the Reader.

5. Excitation field

generated by the

Exciter is below

Specifications.

5.1. LF

Transmitter

Output is low.

5.1.1. The LF antenna loop

has a loose connection, or

the LF antenna is detuned

by a metallic object.

1. Check whether the LF antenna wires are connected

to the terminal block (See LF Antenna Connections

on page 3-3).

2. Check the 3-wire connection between the LF

antenna terminal block and the LFA21 assembly

(terminal block TB2).

3. Check whether the recommended setup guidelines

for the Exciter’s location are met. Pay special

attention to metallic surfaces surrounding the

Exciter, short-circuit loops, and the spacing between

adjacent Exciters.

6. The Exciter

responds with CA at

the Self-Diagnostic

Procedure.

6.1. Exciter k

responds with CA

at the command:

:TEST:EXCITER

k sent by the Main

PC (k is the

Exciter’s

address).

6.1.1. A faulty Exciter or a

loose connection in the

power cable or

communication cable

between the Reader and

the Exciter.

1. Check the power cable and the communication

cable between the Reader and the Exciter.

2. Check the Exciter’s address setting.

3. Check the LF Transmitter’s output. (See LF

Antenna Connections on page 3-3).

7. The Exciter

responds with C9 at

the Self-Diagnostic

Procedure.

7.1. Exciter k

responds with C9

at the command:

:TEST:EXCITER

k sent by the Main

PC (k is the

Exciter’s

address).

7.1.1. A large magnetic

coupling between 2

adjacent Exciter EX21

frames

1. Check the Exciter’s TAP voltage. (See LF

Transmitter Output on page 5-8).

2. Reposition the EX21 frames to minimize the

unwanted modulation.

3. Only if absolutely necessary, consider readjusting

the C9 threshold (NVT). Refer to LF Transmitter

Output on page 5-8

7.1.2. The LF antenna is

detuned by metallic

objects that are in close

proximity.

1. Check the Exciter’s VTAP.

2. Reposition the EX21 frames to minimize the

detuning. If this is not practical, consider re-

adjusting the antenna for a larger output or reduce

the C9 threshold. Refer to LF Transmitter Output on

page 5-8

8. The Reader does

not communicate to

the PC.

8.1. No response

from the Reader,

intermittent

response or

garbled response.

8.1.1. RS485 cable wires

are damaged. 1. Isolate the problem area by checking

communication with other Readers located before

or after on the RS485 bus.

2. Inspect the installation specifically looking for

pulled out or damaged cables or bad contacts.

8.1.2. Program in the

Reader is not running due

to internal failure.

1. Get access to the Motherboard and see that Data

LED is OFF.

2. Push RESET button once. Data LED should start

blinking.

3. Push RESET button again. Data LED should go

OFF. If this is not happening, the Reader program is

not running properly and the Reader has to be

replaced.

8.1.3. RS485 interface in

the Reader is damaged. 1. Find all the Readers on the bus that are not

communicating. Perform the following steps with

each of them.

2. Disconnect RS485 bus terminal block/s from the

Motherboard.

3. Locally connect Laptop to the Reader using RS485

Tester and Connecting Board CBD16 (refer to

Figure 5-2 in Chapter 5).

4. Set the line termination jumper on the Motherboard

to Load and RS485 Tester attenuation switch to ON.

Check if you can communicate to the Reader using

the correct address. If not successful, replace the

Reader.

5. Reconnect the bus, place the termination jumper to

its original position and move on to the next Reader.

6. Reapeat steps 2 through 5 until all Readers are

checked.

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”.

Start = a string of 13 bits “0101010000111”.

SC = 2 bytes system code; transmitted only if TS=Y.

UD = user definable data; number of bytes is set by CC (1 to 32).

GateID = 1 byte with received gate ID.

Cntrl = 1 control byte.

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.

Parameter Range Description

DR 4Data rate; 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

TF Y/N Transmit Flags

TS Y/N Transmit System Code

SYNC START SC UD GateID Cntrl CRC KEY FLG

Message Format

B-2 Transponder PT21 Messages

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.

The following is the method of evaluating the maximum transmission time for the PT21:

Number of bytes per message: TXBytes = SC + UD + GateID + Cntrl + CRC + Flag + Key

Number of bits per byte: BitsPerByte = 12 for DR4

Number of bits per message: TXBits = Sync + Start + BitsPerByte*TXBytes

Bit duration: BitLen = 1/38400

Message length: MsLen = 0.0007 +TXBit*BitLen

Intermessage constant: InterMsgUnit = (SC+UD+2+CRC+Key+Flag)*0.0003066, for DR4

Intermessage delay: InterMsgDelay = [SD +RND(0…31)]*InterMsgUnit;

(RND - random value)

Maximum number of transmitted messages: NM = IP +RC; if LT = Y

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.

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).

Upgrading the Firmware

Upgrading the firmware involve the following steps:

1. Setting the Reader’s Address to 0

2. Saving parameters (those that are different from default)

3. Upgrading the firmware itself by using:

a) The RS232 interface

b) The RS485 interface: 4-wire communication line or 2-wire communication line

3. Restoring parameters

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 5-17.

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.

Note To determine a parameter’s value, for example, DCI, type the following command:

DCI<Enter>

For example, the Reader responds:

DCI=30

where 30 is the parameter value.

3. 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.

4. Send:

:CONFIG:DEFAULT<Enter>

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 21 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 5-4. 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>

Upgrading the Firmware

Reader Software Upgrade Procedure D-3

The Reader must respond with the new firmware version number, for example:

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

following conventions for the connections between the Reader RD21 and the PC:

A <--> TX+; B <--> TX-; Z <--> RX+; Y <--> RX-.

2. To upgrade the Reader’s software, follow steps Steps 2 - 5 in Using the RS232 Interface

above.

Upgrading the Firmware

D-4 Reader Software Upgrade Procedure

Restoring Parameters Follow these steps:

1. Verify whether parameters were set to default during the upgrade procedure, by checking their

values. If yes, then reset their values to the saved values (see Saving Parameters on Page D-2).

Note a) Reader firmware 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 Parameters step, or restart the configuration process as described in

Chapter 5, Configuration and Operation.

3. Check the values of the new parameters, if any, that were introduced by this software version.

Setting the Reader’s

Network Configuration To set the Reader’s network configuration, do the following:

1. Set the Reader’s address to its 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.

Upgrading the Firmware

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.

Reader Hardware Calibration Procedure E-1

Appendix E

Reader Hardware Calibration Procedure

This appendix describes the procedures for storing and resetting the calibration data in the Reader

RD21 (P/N 600002). This procedure must only be used in a controlled lab environment.

When first manufactured, certain calibration parameters (special parameters) are stored in a

permanent memory location in the Reader. Once stored, these parameters are not affected by the

:CONFIG:DEFAULT, :CONFIG:REVERT commands or firmware upgrades. Neither can they be

manually changed. These are board specific parameters and as such should remain untouched for

the service life of the board.

The special parameter group includes:

HV0, HV1, HD0, HD1, ISN and ISC.

For detailed explanations refer to the RFID System S21 Reference Guide.

Introducing Special

Parameters When REC21 board is powered up for the first ime (during manufacturing), the Data LED starts

flashing with a 1sec interval. This flashing indicates that special parameters are not stored. All

special parameters must be set to the proper values for the board to be operational.

Introduce all special parameters, when done, the Data LED stops blinking. At this point the service

person must carefully check for any typos or wrong values. If an error occured when introducing a

parameter, the Reader has to be reset and all special parameter values reintroduced anew.

After making sure that all calibration parameters are correct and Data LED is OFF and not blinking,

send

::CONFIG:HW<Enter>

This finalizes the permanent storage of calibration (special) parameters.

Notes In certain special cases, it could be neccessary to change the calibration values set at production

time. To return the Reader to the pre-production state, do the following:

1. Turn OFF Reader’s power.

2. Press and hold down the Reset Button on the Motherboard.

3. Turn ON Reader’s power without releasing the Reset Button.

4. Wait 7sec and release the Reset Button.

5. Make sure that the Data LED is now flickering at a 1Hz rate.

6. Go to Introducing Special Parameters.
