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 may be in the 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.
95 Series RFID System 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.
95 Series RFID System Configuration Principles settings that control the hardware configuration, is described in Chapter 3, Theory of Operation in the 95 Series RFID System Technical Guide. This chapter gives reasons for using certain parameters for configuring the hardware. System Code A Reader R95 needs a System Code to function properly. You use the ISC parameter to set the System Code the first time.
95 Series RFID System Configuration Principles For the software reset, press the RESET button on the Motherboard MBD95 twice, or type the command: :RESET The software reset resets the Microcontroller. The hardware reset resets the Microcontroller and runs a complete memory test. Exciter Address When an Exciter E95 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 EXT95SC board.

Before You Begin Chapter 5 Configuration and Operation This chapter explains how to set-up and configure a 95 Series RFID System. The IPC implementation is a practical example of the 95 Series RFID System configuration. For more information about the 95 Series RFID System configuration, refer to the 95 Series RFID System Technical Guide. Before You Begin Before starting the RFID System 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 RS-232 or RS-485 communication line to connect the Reader to the PC. For more information on these communication lines, see Connecting the RS-232 Communication Line, and Connecting the RS-485 Four-Wire Communication Line in Chapter 2. For the initial set-up, Lyngsoe recommends using the RS-232 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. Turn on the power supply to the Reader. 2. Referring to Figure 5-1, check whether the relay on the MBD95 board immediately clicks, and the green POWER LED is on. 3. Check whether the Reader performs the following power-on test sequence: the red DATA LED on the MBD95 board remains ON for 6-7 seconds.
Resetting the Reader using Group S parameters. You can change the settings for the PC or Reader so that the settings match each other. If you modify the Reader’s parameters, you must save them before leaving the learning mode. For more information on this procedure, see Storing the Reader’s Configuration on page 5-13. 6. Press the RESET button again to exit from the learning mode. 7. Notes The DATA LED will stop flashing. 1.
Setting Up the Exciter’s Address 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 CRM95 board, set it to the correct value.
LF Transmitter Output 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. Note Addresses 00002 and 11112 are reserved for special modes of operation.
LF Transmitter Output The Reader will respond with the parameter value, for example, HE1=6 where 6 is the value for the HE1 parameter. 3. Set the Continuous DC Mode type of execution, by typing: RCS=N RES=N REM=C RET=D Note If a parameter already has the wanted value (determined in Step 2), you do not have to reset it. 4.
Configuring the Reader For example, Lyngsoe recommends the following parameter values for the Conditional Switching AC mode (CSAC) for the IPC installation: RCS=Y; RES=Y; REM=C; RET=A; HCC=8; HCS=7; HE0=18; HE1=6 These parameters all have the default values. 8. Check the excitation field pattern as set in Step 7, by monitoring the TAP voltage. For example, if the IPC’s CSAC mode was set and the Reader did not receive a valid message, the TAP voltage has the following repetitive pattern: a carrier of 128.
Setting Up the Carrier Threshold 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 and set the data report in ASCII format, by typing the following: DAR=Y DHX=N To setup the Reader’s carrier threshold, do the following: 1. Switch off the excitation field, by typing: C 2.
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 5. IMPORTANT * For a normal setup, the value of (HNL+RSS) must be less than - 85 dBm.
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. Set the parameters you want for the Test-Tag using the Group W parameters.
Setting Up the Real Time Clock received, verify whether the UHF channel is jammed or replace the EXT95SC board. Note If you do not see the expected number of messages on your PC, (13-15 messages for an IPC site), see Chapter 7, Troubleshooting and check the following parameters: DAR=Y; DCI=0, DRI=0 6. Repeat Steps 1 to 5 for each Exciter that is connected to the Reader. Setting Up the Real Time Clock You can set the Reader’s date and time by using the IUT parameter.
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. Set all jumpers (J1-J4) placed on the Motherboard MBD95 according to the type of communication line used for the network. For more information on communication lines used by the Reader R95, refer to Chapter 2, Reader R95 Installation and Connections. 3.
95 Series RFID System - Final Test If there is no unwanted transmission on the UHF channel, the Reader must respond with a value lower than -95dBm for the HNL parameter. If not, refer to Setting Up the Carrier Threshold on page 5-9. 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.
95 Series RFID System - Final Test e) Check the received messages, by typing: @r D or @r :DATA:REPORT 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 For an IPC application, the Reader’s Tag Record Buffer contains 13-15 identical messages sent by the Exciter k’s Test Tag in ANS.1 format.
Setting Up the Programming Site Chapter 6 Programming and Testing the Transponder T95 This chapter explains how to setup a site and gives the procedure for programming the Transponders T95. This chapter does not, however, explain how to choose parameter values. For more information on configuring the Transponder 95, see the 95 Series RFID System Reference Guide.
Programming Procedures 4. Power-up the Programmer PGM95 from an AC power supply 9Vac + 10%, 50/60 Hz, or a DC power supply 11 to 14 Vdc. The maximum power supply is 0.5A. Programming Procedures Place the Transponder T95 inside the special slot of the PGM95, with the component side (battery side) down, and gently push it until it is inside the PGM95.

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 5-13. 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 Solution The configurations of the 1. Using a Test Transponder TST95 that has been programmed for your Transponder and the application, test the Reader’s Reader do not match. 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 Solution The LF antenna loop has 1. Check whether the LF antenna wires are connected to the terminal a loose connection, or the block (See LF Antenna Connections LF antenna is detuned on page 3-3). by a metallic object. 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 R95 (P/N 600405) main software using the serial interface RS232 or RS485. This software controls the functionality of the Microcontroller placed on the Receiver assembly CRM95 (P/N 500056). 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. 3. Reset the parameters HV0, HV1, ISC, ISN to their original values prior to the upgrade process. You recorded them during the Saving Parametersstep. Note a) Firmware V1.68.02 ignores leading zeros for integers.
Upgrading the Firmware Final Instructions 1. You must repeat this procedure for each Reader R95 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 R95 configuration, see Chapter 5, Configuration and Operation.
