Transponder Identification System 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.
RFID Specific Terms 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.
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.
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.
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 an unique address. You can set the Exciter’s address in a binary format between 0001 and 1110, using the S1 switch on the LFA21 board.

Before You Begin Chapter 5 Configuration and Operation This chapter explains how to set-up and configure a RFID System S21. The IPC implementation is a practical example of the RFID System S21 configuration. For more information about the RFID System S21 configuration, refer to the RFID System S21 Technical Guide. Before You Begin Before starting the RFID System S21 configuration, do the following: 1.
Setting Up the Reader/PC Connection Setting Up the Reader/PC Connection To connect the Reader to a PC, do the following: 1. Use the RS232 or RS485 communication line to connect the Reader to the PC. For more information on these communication lines, see Connecting the RS232 Communication Line, and Connecting the RS485 Four-Wire Communication Line in Chapter 2. For the initial set-up, Lyngsoe recommends using the RS232 connection with a local, mobile PC (Laptop), as shown in Figure 5-1 below.
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 green POWER LED is on (See Figure 5.1). 3. Check whether the Reader performs the following power-on test sequence: the red DATA LED on the MBD21 board remains ON for 6-7 seconds.
Resetting the Reader learning mode. For more information on this procedure, see Storing the Reader’s Configuration on page 5-14. Notes 6. Press the RESET button again to exit from the learning mode. 7. The DATA LED will stop flashing. 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.
Checking the Reader’s Basic Parameters 2. Check the System Code (SC), by typing: ISC The response should be: ISC= [your SC] If the displayed System Code is not identical with the application system code number, replace the Reader and report the problem to Lyngsoe. 3. Check the Receiver’s Serial Number (SN), by typing: ISN [your SN] If the displayed serial number is not equal to the serial number on the Receiver’s REC21 board, set it to the correct value.
Setting Up the Exciter’s Address Setting Up the Exciter’s Address Your next step is to setup an address for each Exciter by using the S1 slide switch on the LFA21 board, as shown in Figure 5-2. 1 1 2 4 2 3 4 3 0 1 2 3 “1" “0" bit Test J1 J2 S21 S95 OFF ON A d d r e s s J5 J4 O L L Figure 5-2: Setting Up the Exciter’s Address The addresses must be sequential between 1 and 14. For example, if there are 4 Exciters, they must be assigned addresses 1, 2, 3, and 4.
LF Transmitter Output LF Transmitter Output The type of LF excitation signals generated by the S21 depends on the parameter settings and the position of “System” jumpers on the LFA21 and CTL21. For “System S21” jumpers J1 (LFA21) and J3 (CTL21) are to be set on S21 position. The LF excitation signal generated is of type EXID. This signal is a continuous OOK signal on 125 KHz. The modulation is a fixed repetitive frame [Excitation ID] containing the address of the reading point. (Reader Address).
LF Transmitter Output 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.
Configuring the Reader 11. Turn off the excitation field again, by typing: C 12. Check the auto-diagnostic feature, by typing: :TEST:EXCITER k The response should be C9. 13. Repeat Steps 1 to 13 (inclusive) for each Exciter that is connected to the Reader.
Setting Up the Carrier Threshold 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).
Setting Up the Carrier Threshold 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 In installations where random interference is observed please contact Lyngso Industri A/S for assistance.
Setting Up the Exciter’s Test-Tag Setting Up the Exciter’s Test-Tag To set up the Exciter’s Test-Tag, do the following: 1. Example Set the parameters you want for the Test-Tag using the Group W parameters.
Setting Up the Real Time Clock 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 You can set the Reader’s date and time by using the IUT parameter. For more information on setting up the Real Time Clock, refer to the RFID System S21 Reference Guide.
Configuring the Reader’s Network Parameters Configuring the Reader’s Network Parameters To configure the Reader’s network parameters, do the following: 1. Set the reporting mode, by typing: DAR=N. 2. Set the Reader’s address, by typing: IAD=r where r is the Reader’s address. The lowest value for this address is 1. For example, if there are 4 Readers in a network, they must be assigned the following addresses 1, 2, 3 and 4.
Reader - Final Setup Reader - Final Setup To verify whether the Reader is responding, do the following: 1. Disconnect the PC from the Reader (See Figure 5-1 on page 5-2). 2. For network installations set jumper (P3) on the Motherboard MBD21 for “RS485” position. For more information on communication lines used by the Reader RD21, refer to Chapter 2, Reader RD21 Installation and Connections. 3. Verify the connections between the Reader and the rest of the equipment (shorts, loose connections, etc.) 4.
S21 RFID System - Final Test c) Check and record the value for the existing Reader’s Carrier Threshold level, by typing: @r HTL The Reader should respond with the value for this parameter. For example, HTL=95.
S21 RFID System - Final Test The Reader must respond with the oldest record sent by the Exciter k’s Test-Tag, in the format set by the DHX parameter. For more information on this parameter, refer to the 95 Series RFID System Reference Guide. Note If the equipment is connected to the Lyngso Industri EDECS Module all setup parameters are set automatically.

This chapter does not, however, explain how to choose parameter values. Transmission parameters are defined and set in the programming software provided by Lyngso Industri A/S. For more information parameter configurations for the Transponder PT21, see the RFID System 21 Reference Guide.
TQ21 Connections Setup the programming site, as shown in Figure 6.1: Power Supply 12Vac [12-16Vdc]/0.3A DB9-Male RS232 Cable DB9-Female PC or Laptop Power LED Data LED Tag Qualifier TQ21 Figure 1-4: P TQ21 Tag Qualifier Setup TQ21 Connections 1. Connect the RS232 cable. Plug one end of the cable (DB9-Male) into the 9-pins connector on the TQ21 (marked as RS232). Plug the other end of the cable (DB9-Female) into the serial port (typical COM1) of your computer. 2. Connect the power adapter.
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.
Firmware Considering the S95 as a reference, the parameters PTA, PTT, PTV and RSM were disabled for TQ21. Firmware For the command IVN, TQ21 will display its firmware version TQ21 v3.01.06. or a higher version. Hardware configuration parameters Several parameters are used to set (configure) the hardware and must not be changed. If the TQ21's firmware is going to be updated, these parameters must be first written down and reprogrammed if were accidentally erased by the upgrading process.
Operation • 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).

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.
General Guidelines The following table describes several possible failures for the 95 Series RFID System, and the troubleshooting steps to correct them. Problem No communication with a Reader. Symptom Reader does not respond to any command. Probable Cause 1. Reader has an incorrect address. Solution 1. Check whether the Reader responds to commands using different addresses, by typing the following: @1 IVN, @2 IVN, @3 IVN.
General Guidelines Problem Symptom Probable Cause Solution 6. If you are able to communicate with the Reader from the local PC, check the integrity of the communication line between the Reader and the PC. 7. After fixing the communication line’s integrity, reconfigure the 95 Series RFID System and check whether the Reader can communicate with the PC. 8. If you cannot communicate with the Reader (Step 5), check Probable Cause 3. 3.
General Guidelines Problem Symptom Probable Cause Solution 7. Store the Reader’s configuration by following the steps in the section, Storing the Reader’s Configuration on page 5-14. Note The HV0 and HV1 parameters are set at the factory during the adjusting procedure and recorded for each Reader. If you know the Reader’s serial number, Lyngsoe can supply you with the values. Reader does not record the Transponder’s messages.
General Guidelines Problem Symptom After the power-on test is finished, the sign-on message is displayed on the PC, and the DATA LED is flashing only when a Transponder is activated. Probable Cause The configurations of the Transponder and the Reader do not match. Solution 1. Using a Test Transponder TST95 that has been programmed for your application, test the Reader’s receiving capability. 2.
General Guidelines Problem Symptom Probable Cause Solution 4. If the value of (HNL + RSS) is higher than -85dBm, there is either an unwanted transmission on the UHF channel, or the value of the RSS parameter is too high. The value for the RSS parameter must be between 10 and 20. 5. Check whether there are Transponders or an Exciter’s Test Tag in the immediate vicinity that transmit messages accidentally. 6.
General Guidelines Problem Symptom Probable Cause Solution range. When using multiple Transponders, some messages are lost due to the inherent collision between them. Time-out error. (At the command :TEST:EXCITER k, the response is 00, but the Main PC does not receive a message, or a correct message from the Test Tag of the Exciter k after a predetermined period of time). DATA LED is flickering, the Reader’s Tag Record Buffer contains messages from the Test Tag. Test tag was incorrectly programmed.
General Guidelines Problem Excitation field generated by the Exciter is below Specifications. Symptom LF Transmitter Output is low (VTAP< 80 Vpp). Probable Cause The LF antenna loop has a loose connection, or the LF antenna is detuned by a metallic object. Solution 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 EXT95SC assembly (terminal block TB2). 3.

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). This procedure refers particularly to the upgrading process for software version 1.68.02. Upgrading the Firmware Upgrading the firmware involve the following steps: 1.
Upgrading the Firmware Saving Parameters Follow these steps: 1. Write down the values of the following parameters: HV0, HV1, ISC, ISN. To determine a parameter’s value, for example, HV1, type the following command: Note HV1 For example, the Reader responds: HV1=125 where 125 is the parameter value. 2. If the Reader was already configured, write down all parameters whose values differ from the set default values.
Upgrading the Firmware The Reader must respond with the new firmware version number: CRM95 V1.68.02, BUILT: 02/03/98 13:01:12 If not, repeat the procedure from Step 2. 7. If after completing Step 5, you still cannot communicate with the Reader, replace the Reader with another unit and return the faulty one to Lyngsoe. Using the RS485 Interface 4-wire Communication Line Follow these steps: 1. Connect your PC (COM port) to a Converter RS232/RS485.
Upgrading the Firmware Restoring Parameters Follow these steps: 1. Verify whether parameters were erased during the upgrade procedure, by typing: ISC 2. If the Reader responds with ISC=0 then the original parameter values were erased and they were set to their default values. Note 3. Reset the parameters HV0, HV1, ISC, ISN to their original values prior to the upgrade process. You recorded them during the Saving Parametersstep. a) Firmware V1.68.02 ignores leading zeros for integers.
Upgrading the Firmware 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.
