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 carpark 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.

1-2 Introduction



RFID System S21 Configuration Principles

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:

IMPORTANT



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.

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.

Introduction 1-3



RFID System S21 Configuration Principles

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.

1-4 Introduction



RFID System S21 Configuration Principles

For the software reset, press the RESET button on the Motherboard MBD21 twice, or type the command: :RESET 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.

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:

Note

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.

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.

Configuration and Operation 5-3



Reader’s Power-up Sequence

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 ] 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

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.

Configuration and Operation 5-7



LF Transmitter Output

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:

3.

Set the wanted TAP voltage to the value required by application (90V recommended for most cases):

NVA=xx,xx - is the value in Volts 4.

Set the wanted C9 threshold voltage to the value required by application (40V recommended for most cases):

NVT=xx,xx - is the value in Volts 5.

To start the Exciter self calibration process send

:CONFIG:EXCITER n 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 :TEST:EXCITER n 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 The TAP voltage amplitude should become zero. 9.

Turn on the LF field again, by typing:

B 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 V TAP due to unwanted modulation should be more than two thirds or 67% of the application required Vpp value.

Configuration and Operation 5-9



Configuring the Reader

To check the Exciter’s current settings including its serial number, do the following: POWER:QUERY:EXCITER n ESN EVT - returns the value of threshold in Volts EVA - 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 POWER:MATCH:EXCITER n POWER:QUERY:EXCITER n EVA - 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 Hardware configuration Instrument generic configuration Tag data reading configuration

-

Group D parameters Group H parameters Group I parameters 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

5-10 Configuration and Operation



Setting Up the Carrier Threshold

DHX=N To setup the Reader’s carrier threshold, do the following: 1.

Switch off the excitation field, by typing:

C 2.

Set the Receiver’s signal-to-noise ratio, by typing:

RSS=10 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 Ensure that both UHF antennas are connected. If you are not using Diversity, disable it by typing:

HAD=N 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 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 or

:CONFIG:THRESHOLD

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.

Configuration and Operation 5-11



Setting Up the Exciter’s Test-Tag

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.

Configuration and Operation 5-13



Configuring Reader Motion Sensor Driven Mode of Operation

Example

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

IUT=YYMMDDhhmmssZ 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.

- special message is generated every time MS changes its status;

5-14 Configuration and Operation



Configuring Exciter Motion Sensor Driven Mode of Operation

ROE=100

- after MS turns inactive, LF field and data buffering remain enabled for 5sec;

DNT=Y

- special message is generated if no tag is received before MS turns inactive;

HMS=24

- special message is generated if MS never turned active in 24hrs;

DIS=Y

- adds special field to the buffered message indicating MS status;

HOA=H

- MS is concidered active when OS line is at +5V;

HOS

- returns the current status of MS (High or Low).

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.

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. Note

There is a fixed extension time of 5sec when the LF field remains ON after MS becomes inactive.

Configuration and Operation 5-15



Configuring the Reader’s Application Parameters

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 2.

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

IFA=Y 3.

Set the data filtration on the Reader, by typing:

Programming and Testing the Transponder PT21

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.

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.

Configuration

6-2



New parameters and commands

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.

6-3



Hardware configuration parameters

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

Testing Tags

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.

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

• • • •

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.

Preventive Maintenance

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.

Symptom

Probable Cause

3.1. Reader does 3.1.1. The receiving zone is too small because of not record all either a high carrier transmitted threshold, or there is messages by the random interference on Transponder. the UHF channel.

Solution 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.

Solution 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.

Troubleshooting 7-7



General Guidelines

Problem

Symptom

Probable Cause 7.1.2. The LF antenna is detuned by metallic objects that are in close proximity.

8. The Reader does not communicate to the PC.

8.1. No response 8.1.1. RS485 cable wires are damaged. from the Reader, intermittent response or garbled response.

8.1.2. Program in the Reader is not running due to internal failure.

Solution 1. Check the Exciter’s VTAP. 2. Reposition the EX21 frames to minimize the detuning. If this is not practical, consider readjusting the antenna for a larger output or reduce the C9 threshold. Refer to LF Transmitter Output on page 5-8

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.

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.

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.

Transponder PT21 Messages B-1



Message Format

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.

Upgrading the Firmware

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

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

Setting the Reader’s Address

3.

Restoring parameters

4.

Setting the Reader’s Network Configuration

5.

Final instructions

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 @r :CONFIG:STORE @r :RESET 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 The Reader must respond with its software version number. If not, repeat Step 1.

Reader Software Upgrade Procedure D-1



Upgrading the Firmware

Saving Parameters

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

Note

DCI 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

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 or type the following shortcut:

F 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 Powerup 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:

D-2 Reader Software Upgrade Procedure



Upgrading the Firmware

The Reader must respond with the new firmware version number, for example: Receiver REC21 (c)Copyright Lyngsoe Systems Ltd. 2003 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

Restoring Parameters

Note

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).

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. Setting the Reader’s Network Configuration

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

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 2.

Store the Reader’s parameters, by typing:

:CONFIG:STORE 3.

Reset the Reader, by typing:

:RESET 4.

Verify that the Reader is functioning properly, by typing:

@r IVN 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.

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 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.
