RFID Specific Terms

Transponder Trans ponders are devices that receive an excitation sig nal, and respond by transmitt ing back a

message. Transponders that are us ed 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-r adi o frequen cy to infra -red li ght. It c an also have a specia l signature (patter n, 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 atta ched), 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.

Read ing Points Reading Point s are installe d at st rategi c areas on the site whe re you want to i dentify obje cts th at are

passing within a specified range. Reading Points generate the excitation signal an d r eceive signals transmitted by the Transponders. Data captured from the Transponders is then tra nsferred 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 mai n com puter and vice-versa.

Communi c at i on Li nks When using Tr ansponders and Reading Poi nts , two wireless communication links exist. They are:

Uplink - from the Rea ding Point to the T r ansponder, and Downlink - from the T r ansponder to the Reading Point.

RFID System Automatic identification systems vary in their complexity. An example of a simple system is a car-

park barrier tha t provides automatic vehicular-access control. A more complex example is a network of on-li ne Readers and Exciters that co mmunicate with a host compute r that is managing an automated industrial facility.

Postal R FID System

The Internationa l P ostal Corporation (IPC) required internationa l end-to-end mail performanc e monitoring to implement new management and financial control systems. This monitoring and controlling is s upp orted by an intern ationa l agreemen t k nown as REIMS (Re munera ting E xchang es of International Mails).

The Postal RFID System was deve loped in response to the IPC’s requireme nts.

The main objective of the Postal RFID System is:

• To monitor the movement of the probe letters at key poi nts 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 Exci ters, you can electronically monitor the path of test letters throug h the collection and delivery process, particularly at points between Postal adminis trations and their agents .

Each probe letter includes a RFID Transponder bearing a unique identification. The probe letters are posted, sor ted, and delivered in the same way as normal letters. As they pass pre-determined points en-rout e (Reading Points/identification z o nes), 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 s pec ific equipment:

• Transponders PT21 carrying the identification data

• Exciters EX21 to generate an electromagnet ic (LF) field that excite s the Transponder PT21

• Readers RD21 to receive data transmitted by the Transponder PT21(UHF) and to relay thi s information via the RS-485 interface to the main computer

• Power Supply TRM95 to power Rea ders RD21 and Exciters EX21 from the local AC main supply.

IMPORTANT This manual refers to S 21 features and equipment associ ated with RFID System S21.

RFID System S21 Configuration Principles

The RFID System S21 is highly config urable, allowing y ou to setup operat ional parameters for the optimum performance of the System. The sections that fol low give some basic information regarding the RFID System S2 1 configuration. A detailed description of the configura tion, with a focus on an IPC implementation, is given in Chapter 5, C onfiguration and Operation.

Communi c at i on Li nks There are sever al communication links between the components of the RF ID System S21. As a

general rule, all equipment attached to a particular link must have the same parameters settings to communicate. Som e comm unication 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-t o-Exciter and Exciter-to-Reader (RS485_COM, RS485_SGN) - fixed configuration.

• Reader- to-Main PC and Main PC-to-Reader (RS232 or RS 485) - configurable.

System Parameters Parameters controlling the RFID Syste m S21’ s con figu ration ar e logi call y org anized in group s. For

a detailed explanation on the meaning and usage of the parameters, refer to the RFI D Sys tem S21 Reference Guide. The parame ters settings that control the hardware configurati on, is described in Chapter 3, Theory of Operation in the RFID System S21 Te chnical Guide. This chap ter gives reasons for using certain parameters for configuring the hardwa re.

System Code A Reader RD21 needs a System Code to function properly. You use the ISC parameter to set the

System Code the firs t time. The System Code is a spec ially encoded number that distinguishes the RFID System from all other similar systems in us e. By obtaining your Sys tem Code from Lyngsoe Systems, you are guaranteed a unique System Code.

Introduction 1-3

RFID System S21 Config ur at i on Pri nc iples

Reader Address When a Reader is part of a network, it mu st 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 addr ess. In this way, you can direct commands ove r the network to a specific Reader .

Real Time Clock T he Reader RD21 ha s an on board Re al Time Clock. Make sure that the date and time are correctly

set. The time ca n be queried and set using the IUT para meter. The pr es ence of the seconds field in the time stamp is optional and is controlle d by the DT S param eter.

Receiving UHF Data The Reader needs to know the data format in which the Transponder is tran smitting informati on to

properly recei ve and interpret the information. The Reader’s se tting can be checked and modified by the Group R parameters.

A simple method of matching an unknown Transponder with the Reader’s parameters setti ng 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 paramete rs 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 monitorin g 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 gre atly simplify the implementation of the monitoring software.

Reader Serial Port When setting the serial port para me ters, 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 Refe rence Guide.

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

• Hardw are reset

• Sof tw a r e re s e t.

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<Enter>

The software reset resets the Micr o controller . T he ha rdware reset resets the Micro controller and runs a complete memory test for receiver REC21.

Exciter Address When an Exciter EX21 is part of a net work, it must have a uniq ue addre ss. You can set the Exciter’ s

address in a binary f ormat between 0001 and 1110, using the S1 switch on the LFA21 board.

Once an addres s is as sig ned, t he Excit er wi ll only proc ess co mmands with a ma tching addr ess fie ld. In this way, you can direct commands in the network to a specific Exci ter EX21.

Compa t ibility wi t h RFID System 95

RFID system S21 can be conf igured as an RFID System S95. By changing the configuration, the S21 system can compl etely simulate the functionality of a S95 syste m. To implement this the following must be done:

•On the Exciter EX21[board LFA21] - se t jumper P1 on the S95 Position.

•On the Reader RD21 [board CTL21] - set jump er P 3 on the S95 pos ition.

•Upgrade Reader RD21 software to ve rsion 6.10.06 or highe r.

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

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

The response should be 00, meanin g tha t the TAP voltage is higher than C 9 thres hold, a nd the Reader should contain in the buffer a mess age from the Test T ag.

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

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

8. Turn of f 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 t hat 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 exc i tation 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 si gnal and adjust the position of the EX21 frames to obtain a minimum unwa nted modulation depth. To do that, the installe r 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

Configuration and Operation 5-9

Configuring the Reader

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

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

command. Note that the default value of these parameters (after the Reader reset) is se t to unreali stic value so that the user does not think that these are actual Exciter settings ( r efer to RFID System S21 Reference Guide).

In orger to set the Exciter T AP voltage, instead of using the :CONFIG:EXCITER n command as described above , the user can iteratively do the following:

NVX=some value<Enter>

POWER:M ATCH:EXCITE R n<En t er>

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 set s its wipe r posit ion. This pos ition wi ll result in a cer tain L F field s trength speci fic to this particular Exciter. The actual field strength can then be checked by query ing the EVA parameter. This procedure can be useful , for example, if the user wants to quickly set the Exciter to genera te the maximum or minimum level of field.

Configuring th e 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 S y stem.

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 cl ose proximity to the Reader; these can accidentally transmit data that can be received by the Reader.

If the HNL value is lower than -105dBm, che ck its value without the UHF antennas attached. The differe nce 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 Ste p 1.

6. Monitor the DATA LED for at least 10 seconds. The LED must not flicker. If it does flicker

occasionally, increme nt the

Programming and Testing the Transponder PT21

This chapter expla ins how to setup a programming site and gives the proc edure for programming the Tra nsponders PT21. This chapte r does not, however, explain how to choose parameter valu es. Transmi ssion 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 us ed to test PT 21/T96/T95 tags and to program tags PT21/T96. The TQ21 is part of the RFID System S21 deve loped and marketed by Lyngsoe Systems. This Chapter gives you a short presentati on of the equipment TQ21 and basic in formation of how to control it through its parameters.

Progr am ming and Testing th e Transponder PT21

Chapter 6

A general overview of the comman ds 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 whic h 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 T erminal 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. Progra mming software can be purchased from Lyngsoe Systems A/S.

1. Connect the RS232 cable. Plu g one end of the cable (DB9-Male) into the 9-pi ns connector on the TQ21 (marked as RS232) . Pl ug th e other end of th e c able (DB9-Fema le) int o th e seria l po rt (typical COM1) of your comput er.

2. Connect the power adapter. Plug the power adapter o u tput into the connec to r marked as

12Vac.

3. Turn on the TQ21 by connecting the powe r adapter into an availabl e el ectrical outlet. The POWER LED goes ON, and the TQ21 performs a brief startup sequence, during which the DATA LED (re d) stays ON continuously for 5-7 s ec onds. After finishing the st artup sequence

the DATA LED must turn OFF and the sign-on message Tag Qualifier TQ21 (c)Copyright Lyngsoe Industries Ltd. 2001 will be displ ayed 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 signaliz e that the power is connected to the TQ21.

•The DATA LED (red) lights continuously during the startup sequence and flashes when UHF signals ar e re cei v ed .

• The TQ21 cannot be used for te st ing if the Data LED randomly flashes after the startup sequence is finis hed. In this case the sensi tivity threshold must be set again and/or the source of unwanted transmi ssion eliminated.

Configuration

6-2

The functionality of the T ag Qualifier TQ21 can be configured by pa ram eters. These parameters can be set from a PC connected through a standard serial int erface RS232 to the TQ21. The parameters and commands supported by TQ21 are quite simi lar with those listed in the Re fere nce 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.

New parameters and commands

When enabled, TQ21 trans m its the received message s using the S21/S96 format for the flags field (i ncluding the ReceivedID information). If disabled, TQ21 transmits the received messages using S95 form at 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 abou t the carrier frequency and f r equency deviation of the rec eived UHF signal (CF and DF). If disabled, TQ21 transmits the rece ived messages using the format defined by DFA parameter.

Parameters and commands disabled

Considering the S95 as a reference, the parameters PTA, P TT, PTV and RSM were disable d 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

Several parameters are used to set (config ure) 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 par amete rs. Th is com mand wi ll se t al l param eter s t o their de fa ult values , this way er as ing the factory settings for the hardware parameters. If you eras e by accident these hardware parameters, TQ2 1 loses it s calibr ation (c apabil ity to m easur e carrier a nd devia tion freq uencie s) and must be recalibrated agai n .

Software configuration parameters

For an optimum operation of TQ21 we recomm end 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 le as t 15 mi nutes;

• 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 "R ef erence Tags" with errors smaller than ±3 kHz.

Testing Tags Using TQ21 it's possi b le 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 carri er 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 message s fo llowing an excitation.

• Flags status . Field FG gives you information regarding the battery stat us and the type of excitation recognized by the tag.

6-4

Remember: To enable the frequency measurement function for the TQ21 pa rameter DFI must be set as DFI=Y and the command B must be active (LF excitation field enabled).

The recommended procedure for testing a tag is the following:

• Check if the tag to be tested (EUT) was outside an LF excitation field for at least 10 s before

testing, and the com mand C is active for TQ21 (LF excitati on disabled).

• Place the EUT inside the slot marked "Postal Tag" on the TQ21, with the batt er y 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 thi s information and to give just the "Pass" or "Fail" mark.

• Send the command C.

Remember: Tag PT21 must be keep at leas t 10 s outside the LF excitatio n field before it can accept a new excitation.

Programm i ng Tags TQ21 is cap able of programming and querying ta gs PT21/T9 6.

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 mu st be kept at least 10 s outside the LF excit ation field (command C active for at

least 10 s) between two co nsecutive 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.

2.1. After the power-on test is finished, the signon message is displayed on th e PC, but the DATA LED is flashing continuousl y at a random rate.

2.1.1. An improper carrier threshold was set, or the re is an unwanted transmission on the UHF channel.

1. Check whether the Reader is r eceiving 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 Transpo nders’ messages, check the nois e level reported by the Reader with and without UHF antennas connected. If the noise level is identical or varies slightl y (±1 dBm), replace the Reader.

5. If the Reader reports a noise level (HNL) abov e -95 dBm, there is unwanted transmission on the UHF channel from an externa l jammer. For proc edures on eliminating the unwanted transmission, refer to Chapter 4, Se tup Guideli nes in the RFI D System S21 Technical Guide.

There is a random dela y cal led InterMsgD elay that occur s be tween two consecutive mess ages. This is implemented to ensure that the del ay time does not repeat itself before 32 messages have occurred.

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

Number of bytes per message: TXBytes = SC + UD + GateID + Cntrl + CRC + Flag + Key Number of bit s per byte: BitsPerByte = 12 for DR4 Number of bits per message: TXBits = Sync + Start + BitsPerByte*TXBytes Bit durati on: BitLen = 1/3840 0 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 - rando m va lu e )

Maximum number of transmitted messages: NM = IP +RC; if L T = 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, usi ng different sets of parameters for the PT21.

Reader Software Upgra de Procedure

Setting the Reader’s Address

3. Upgrading the firmware its elf by using:

a) The RS232 inter face

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

3. Restoring parameters

4. Setting the Rea der’s Network Configura tion

5. Fi nal instructions

To set the Reader’s address, do the following:

1. If the Reader already has an address, f o r exampl e r, then set thi s address to 0 by typing the

follo wi n g commands:

@r IAD=0<Enter> @r :CONFIG:STORE<Enter> @r :RESET<Enter>

For more information, refer to Stor ing the Reader’s Configuration on page 5-17.

2. Check whether the Rea der’s address is 0, by typing the following command:

IVN<Ente r>

The Reader must respond wit h its software version number. If not, repeat Step 1.

Reader Software Upgrade Procedure D-1

Upgrading the Firmwar e

Saving Parameters Follow these steps:

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

DCI<Enter>

For example, th e 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 instal latio n, writ e down the values for the followi ng paramet ers: 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 Rea der RD21 (RS 232 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 fil e. Lyngsoe

recommends having the ne w file on your hard drive and not on a floppy disk.

4. Wait until th e tr ansfer pro c es s is complete . If th e 21 Se r ie s RFI D S ystem aborted the transf er

process, repeat S tep 2.

5. If the downloading proc ess was successful, wait for the Re ade r 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:

D-2 Reader Soft ware Upgrade Procedure

IVN<Enter>

Using the RS485 Interface

Upgrading the Firmware

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

If not, repeat the p rocedure from Step 2 .

7. If after comple ting Step 5, you still cannot communicate with the Reader, replace the Reader with another unit and return the faulty one to Lyngsoe.

4-wire Communication Line

Follow these step s:

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 communicat ion line connection to th e Read er, refer to Connecting the RS485 Four-Wire Communication Line on page 2-3 and Setting Up the Reader/PC Connectio n 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 soft ware , follow steps Steps 2 - 5 in Using the RS232 Interface above.

Reader Software Upgrade Procedure D-3

Upgrading the Firmwar e

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 save d values (see Saving Parameters on Page D-2) .

Note a) Reader firmware ignores leading zeros for int ege rs .

b) If the Reader was already configured on the site, you have to restore all application parameters

queried during the Saving Parameters step, or rest art the configuration process as described in Chapter 5, Configuration and Operation.

3. Check the values of the new parameters, if any, that wer e introduced by this soft ware 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 tha t the Reader is functioni ng properly , by typing:

@r IVN<En te r >

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

5. Verify that the para me ters set in the fo llowing sections are correct:

• Steps 2 and 3 from the section, Restoring Parameters above.

• Step 1 in this se ction.

D-4 Reader Soft ware Upgrade Procedure

Upgrading the Firmware

Final Instruc tions 1. You must repeat this procedure for each Reader RD21 that is installed on the site.

2. Lyngsoe recommends using the RS232 or RS 485 4-wire communication line to upgrade the

Reader’s software (these are more reli able commun ication lin k s).

3. For more information on the Reader’s RD21 configuration, see Chapter 5, Configuration and

Operation.

Appendix E

Reader Hardware Calibration Procedure

This appendix describes the procedures for storing and resetting the cal ibration 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 (s pec ial parameters) are stored in a permanent memory location in th e 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 serv ice life of the boar d.

The special parameter group includes:

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

For detailed explanat ions refer to the RFI D System S21 R eference Gu id e.

Introducing Special Parameters

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

When REC21 board is powered up for th e 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.
