It also gives information on the RFID System S21 configuration principles. Transponder Identification System The purpose of a data capture or identification system that uses a Transponder as an identification token is: • To automatically identify animate or inanimate objects having attached a Transponder with an unique identifier • To ensure that information is available in a format that can be readily accepted by a computer • To minimize the possibility of errors in the identification process. The concept of Radio Frequency Identification (RFID) is presented in Figure 1-1.

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: • • • 1-2 Introduction To monitor the movement of the probe letters at key points in the system To supply evidence of mailing system performance To highlight problem areas. RFID System S21 Configuration Principles 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 Industries, 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. 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: :RESETThe 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. 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 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 4.01.06 or higher. For more information regarding communications and upgrading firmware - see Appendix D Introduction 1-5 RFID System S21 Configuration Principles 1-6 Introduction Before You Begin Chapter 2 Reader RD21 Installation and Connections This chapter explains how to: • • • • Install the Reader Module Assembly into the Reader’s enclosure Connect the serial interfaces and the power supply Set the jumpers for interfaces Connect the external devices to the Reader RD21 (optional) Before You Begin Before installing the Reader: • Read Chapter 4, Setup Guidelines in the RFID System S21 Technical Guide. • Have at your disposal, the complete approved documentation describing the RFID System configuration, equipment location, and wiring distances between the equipment (see the Site Survey Documentation). • Check whether the Reader’s enclosure, power supply and interconnection cable with the main PC are installed on the site according to the approved documentation (see the Site Survey Documentation). • Set a color table for each interface and power supply cables.

The IPC implementation is a practical example of the RFID System S21 configuration. For more information about the RFID System S21 configuration, refer to the RFID System S21 Technical Guide. Before You Begin Before starting the RFID System S21 configuration, do the following: 1. Check whether all equipment is correctly installed and interconnected according to the requirements stated in Chapter 2, Reader RD21 Installation and Connections and Chapter 3, Exciter EX21 Installation and Connections in this guide. 2. Check if each Reader and Exciter has a unique address according the approved documentation describing the RFID System configuration (see the specific Site Survey documentation). 3. Familiarize yourself with the instructions format described in the RFID System S21 Reference Guide, and the system’s functionality described in the RFID System S21 Technical Guide. 4. Refer to the section, RFID System S21 Configuration Principles on page 1-3, for some general explanations on configuring the RFID System S21. Pay special attention that the jumpers on the CTL21 and LFA21 are set for S21 operation. General Procedure Rules Each Reader and Exciter in the RFID System must be configured individually. Lyngsoe recommends that you follow the general rules listed below: 1. Configure each Reading Point, one by one. Each Reading Point is defined and controlled by a reader. Configuration of the Reader and interconnected Exciters is accomplished by connecting a PC to the serial communication link. 2. Follow the step-by-step instructions described in this chapter. 3. If you do not obtain the expected results, refer to Chapter 7, Troubleshooting. Configuration and Operation 5-1 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. CNO COM CNC + - + 8V DTA PWR OS I/0 DATA [Red LED] DATA Controller CTL21 Power [Green LED] POWER S95 S21 RESET Button RESET J3 J3 J1 J2 Load Load Open Open J1 P3 J2 Open Open Load Load AB ZY AB ZY RS485 RS232 Interface Selection TX GND RX TX GND RX Laptop RS232 Cable Figure 5-1: Connecting the Reader to a PC/Laptop 2. Run a terminal emulation program on the PC, such as, Hyper Terminal in MS Windows. The recommended configuration for the PC’s port is: • • • • • 5-2 Configuration and Operation Data rate Data bits Parity Stop bits Flow control 19200 bps 8 bits none none 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. Afterwards, the following sign-on message is displayed on the PC’s screen: Receiver REC21 (C) Copyright Lyngsoe Industries Ltd 2002. Notes 1. If you did not assign a System Code identification number (SC) to the Reader, the DATA LED will flash On and Off at a rate of 1.4 Hz. 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 Configuration and Operation 5-3 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. If the noise and interference level on the UHF channel exceeds the carrier threshold or a Transponder is transmitting information, the DATA LED will start flashing at a faster rate. Resetting the Reader There are 2 ways to reset the Reader (see Figure 5-1): • • By resetting the hardware By resetting the software For a hardware reset, switch off the Reader’s power supply for a least 5 seconds. For a software reset, you can: 1. Press the RESET button twice. or 2. Type the following command at the prompt: :RESET Checking the Reader’s Basic Parameters To check basic parameters of the Reader, do the following: 1. Check the software version number by typing: IVN The response should be: IVN=REC21 V5.00.01., BUILT: __/__/__ __:__:__. Note 5-4 Configuration and Operation You can upgrade the Reader software, if necessary. For more information on upgrading the software, refer to Appendix D, Reader Software Upgrade Procedure. Checking the Reader’s Basic Parameters 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. For example, if the SN is U123456, then type: ISN=U123456 4. Store the new SN and/or SC parameter values, by typing: :CONFIG:STORE :RESET 5. Check if the IVN, ISC, and ISN parameters have correct values, by repeating 6. Switch off the LF field, by typing: Steps 1 to 3. C Configuration and Operation 5-5 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. 2 3 4 “1" “0" bit Test J1 J2 S21 S95 OFF ON J5 J4 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. 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 5-6 Configuration and Operation Figure 5.2 displays the S1 setting for address 1. 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). 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 is a continuous signal as defined in the Appendix C of the 95 Series RFID Systems User’s Guide. To check the LF signal, refer to Figure 5-3 below, and do the following: J4 S21 S95 J5 J2 J1 Test GND ANT TAP Oscilloscope To LF Antenna Terminal Block Figure 5-3: LF Signal Measurement 1. Connect the power to the Exciter. 2. To determine the Exciter mode of operation following the field application note instructions provided with the equipment. For additional information or questions contact Lyngsoe Industries. 3. For checking of LF signal integrity refer to the field application notes provided with the equipment or contact Lyngsoe Industries. Configuration and Operation 5-7 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. The installer has to monitor the TAP signal and adjust the position of the EX21 frames to obtain a minimum unwanted modulation depth. 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. The minimum amplitude of VTAP due to unwanted modulation must be larger than 60Vpp. 4. Turn off the excitation field, by typing: C The TAP voltage amplitude should be zero. 5. Turn on the LF field again, by typing: B The TAP voltage signal should have the same value as measured in Step 4. 6. Set the wanted excitation mode. To set a specific excitation mode, refer to Appendix C, Excitation Modes. If you want to return to the initial excitation mode as determined in Step 2, you have to restore the values of the parameters modified in Step 3. 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. 7. 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 125.00 kHz modulated ON/ OFF with 610Hz for 60 ms, followed by no signal for 180 ms. 8. Save the excitation mode set in Step 7, by typing: :CONFIG:STORE :RESET 9. Check the parameter values set in Step 7 again. 10. Check the auto-diagnostic feature, by typing: :DAR=Y :TEST:EXCITER k where k is the decimal address (1, 2, 3,...) of the Exciter that you want to test. The response should be 00, followed by a number (between IP-2 and IP) of messages from the Test Tag. 5-8 Configuration and Operation 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. 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 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 Configuration and Operation 5-9 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). 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. 5-10 Configuration and Operation 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. IMPORTANT For a normal setup, the sum of (HNL+RSS) must be less than - 85 dBm. If the noise level is higher than -95 dBm, disconnect the UHF antennas from the Reader, and check whether the HNL value drops below -107 dBm. If this occurs, it means that there is unwanted transmission on the UHF channel. To correct this situation, refer to Chapter 4, Setup Guidelines in the RFID System S21 Technical Guide. 7. Place your Test Transponder PT21 1-2 m away from an Exciter that is controlled by the Reader you are configuring. For more information about identification zones and the Test Transponders, refer to Chapter 4, Setup Guidelines in the RFID System S21 Technical Guide. 8. Start the excitation field, by typing: B 9. Verify that the DATA LED is flickering, and check whether the Test Transponder’s messages are displayed on the PC’s screen. If data is not displayed, check the Reader’s parameter configuration, and follows the troubleshooting instructions in Chapter 7, Troubleshooting. If the number of displayed messages is below n=IP-2, check the carrier threshold and try to adjust it again. Go to Step 1. 10. Remove the Test Transponder from the field and make sure that it is no longer transmitting by ensuring that the DATA LED is not flickering. Configuration and Operation 5-11 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. For an IPC application, you have to program the following parameters, by typing: WDR=4 WEC=Y WEN=N WHF=N WID=0 WIP=15 WLT=Y WRC=0 WRS=0 WSD=15 WSM=Y WTF=Y WTS=N WWP=Y WUD=$43FEnnrrkk where: nn is the PC’s address. If PC’s address is 1, or there is only one PC/site, nn=01. rr is the Reader’s address. If Reader’s address is 1, rr = 01. kk is the Exciter’s address. If the Exciter’s address is 1, kk = 01. 2. Turn off the LF field, by typing: C 3. Program the Exciter Test-Tag, by typing: :TAG:MATCH:EXCITER k where k is the address of the Exciter you want to program. If the response is not 00, the Exciter is not programmed. Repeat this command several times, waiting at least 3 seconds between retries. Note If you cannot program the Test Tag, see Chapter 7, Troubleshooting. 4. Turn on the LF field, by typing: B 5. Test the Exciter Test-Tag, by typing: :TEST:EXCITER k where k is the address of the Exciter you want to test. The correct response is 00, followed by a number of messages between IP-2 and IP. If less messages are received, verify whether the UHF channel is jammed or replace the LFA21 board. 5-12 Configuration and Operation 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. 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. 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 example, for an IPC application, do the following: 1. Set the data filtration on the Reader, by typing: DCI=10 DRI=30 2. Set the reported data format as ANS.1 format, by typing: DHX=Y 3. Set the Tag data character count, by typing: RCC=5 4. For System S21 operation set RMY =Y, DTS=Y, IUM = Y, and PME=Y 5. Use the default values for all the other parameters. Configuration and Operation 5-13 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. Storing the Reader’s Configuration To store the Reader’s configuration, do the following: 1. Store the Reader’s parameters, by typing: :CONFIG:STORE 2. Reset the Reader, by typing: :RESET Note The:CONFIG:STORE command stores the current Reader’s configuration in the non-volatile memory. The:RESET command updates the contents of the working memory from the non-volatile memory. 3. Check whether the Reader is operating properly, by typing: @r IVN where r is the Reader’s address. The Reader must respond with its software version number. 5-14 Configuration and Operation 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. Close the Reader’s enclosure. S21 RFID System - Final Test IMPORTANT These tests must be done after all Readers and the Main PC are connected to the network according to the site documentation. The PC must be connected using an appropriate serial communication interface. To communicate with the Reader, either use a terminal emulation program, such as Hyper Terminal or Procomm in MS Windows applications, or the dedicated service module of the application software running on the Main PC. All commands to the Reader must include the address field @r where r is the Reader’s address (an integer followed by a blank). You must repeat the following procedure for each Reader that is connected to the Main PC. For the final test, do the following: 1. Verify that the Reader is communicating with the Main PC, by typing: @r IVN where r is the Reader’s address. The Reader must respond with the software’s version number. 2. Set up the Carrier Threshold for the Reader as follows: a) Switch on the excitation field, by typing: @r B b) Check the noise level, by typing: @r HNL 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. Configuration and Operation 5-15 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. d) If the HNL level measured in Step b) is lower than -95dBm, set the Reader’s Carrier Threshold level again, by typing: @r S or @r :CONFIG:THRESHOLD The Carrier Threshold level setting is correct if the new HNL level displayed is smaller than or equal to the level displayed in Step c. If not, check for unwanted transmission on the UHF channel. You should also refer to Chapter 4, Setup Guidelines in the RFID System S21 Technical Guide. 3. Verify that an Exciter that is controlled by a Reader communicates with the Main PC: a) Delete all Tag records from the Reader’s buffer, by typing: @r :DATA:PURGE b) Confirm that the Reader’s buffer is empty, by typing: @r D or @r :DATA:REPORT The Reader must report a Null value. Note For an IPC application, the data structure conforms to the ANS.1 standard. If the Reader’s buffer is empty, the Reader sends a Null value of $0500. In ASCII format, the Null value is { }. c) Switch on the LF field, by typing: @r B d) Send a Test Exciter command, by typing: @r :TEST:EXCITER k where r is the Reader’s address and k is the Exciter’s address. The correct Exciter’s response is 00. e) Check the received messages, by typing: @r D or @r :DATA:REPORT 5-16 Configuration and Operation 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. For an IPC application, the Reader’s Tag Record Buffer contains 13-15 identical messages sent by the Exciter Test Tag in ANS.1 format. To read all messages, you have to repeat the commands: @r D @r E until you get the Null value $0500. f) Empty the Reader’s Tag record buffer, by typing: @r :DATA:PURGE g) Confirm that the Reader’s buffer is empty, by typing: @r :D or @r :DATA:REPORT The Reader must report the Null value ($0500) in ANS.1 format. 4. Repeat Step 3 for all Exciters controlled by the Reader r. 5. Repeat Steps 1 to 4 for all Readers that are connected to the same PC. Configuration and Operation 5-17 S21 RFID System - Final Test 5-18 Configuration and Operation 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 Lyngso Industri 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 Industries. 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 12-16Vdc, 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 Lyngso Industri A/S. 6-1 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. 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 (green) 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. • • • Configuration 6-2 IMPORTANT NOTE The Power LED (green) lights to signalize that the power is connected to the TQ21. The DATA LED (red) lights continuously during the startup sequence and flashes when UHF signals are received. The TQ21 cannot be used for testing if the Data LED randomly flashes after the startup sequence is finished. In this case the sensitivity threshold must be set again and/or the source of unwanted transmission eliminated. New parameters and commands 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. Parameter:PME Type:Bit (Read/Write) Range:Y/N Default value:Y Description:Enable (Y) or disable (N) the transmission of the excitation signals using a Manchester encoding format. When disabled, TQ21transmits the excitation signal using the S95 format. If enabled, TQ21 ignores the status of the parameters REN and RTF (it operates with the default values REN=N and RTF=Y). Parameters and commands disabled 6-3 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. These parameters are: HA0, HA1, HA2, HA3, HA4, HA5, HA6, HA7, HA8, HA9, 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: • • • • 6-4 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 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). 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 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 tag PT21/T96. The procedure of programming and querying is identical with the procedure used for tags T95 described in the User's Guide RFID S9. 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. • • • The tag programming function is performed without being necessary to change the status of parameter DFI (works with DFI=Y and DFI=N). 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 M and/or Q. 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. 6-5 Operation 6-6 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 95 Series RFID System, refer to the RFID System S21 Reference Guide. 3. Information regarding the RFID System S21 configuration and operation is described in Chapter 5, Configuration and Operation. 4. The locations of the DATA LED, the POWER LED, and the RESET button are shown in Figure 5-1. 5. All the reference to commands are made assuming that the Reader’s address is 0. Troubleshooting 7-1 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 . When a correct address is sent, the Reader will respond with its version number. 2. If, by using a specific address, you are able to communicate with Reader, use this address or change the address to another value. 3. If after checking all possible addresses (up to 31), you still cannot communicate with the Reader, check Probable Cause 2. 1. Open the Reader’s enclosure and connect the PC directly to the Reader using the RS-232 communication line. See 2. Faulty communication line Connecting the RS232 Communication between the Reader and Line on page 2-2. PC. 2. Switch off the Reader’s power supply for at least 5 seconds, then perform the steps in the Reader’s Power-up Sequence on page 5-3. 3. If the Reader performs the power-on test successfully, press the RESET button once. Check whether the DATA LED starts flashing at the rate of 2 Hz. 4. Press the RESET button again. Check whether the DATA LED stops flashing. 5. Check whether the Reader is responding to local commands by typing: @r IVN, and pressing , where r is the Reader’s address. The Reader must respond with its version number. 7-2 Troubleshooting 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. Reader lost its System Code Identification number and other configuration parameters. 1. Open the Reader’s enclosure and connect the PC directly to the Reader using the RS-232 communication line. See Connecting the RS232 Communication Line on page 2-2. 2. Switch off the Reader’s power supply for at least 5 seconds, then perform the steps in the Reader’s Power-up Sequence on page 5-3. 3. If the power-on test is successful, the DATA LED should start flashing continuously at the rate of 1.4 Hz. 4. Check the System Code number by typing: ISC, and pressing . If the Reader responds with ISC = 0, setup the Reader’s System code again by typing: ISC = your SC, and pressing . 5. If the Reader restored one of its parameters to the default value, all other parameters are also reset to their default values. Check and reset all the application- specific parameters to their original values. 6. Check the HV0 and HV1 parameter values. If these parameters have default values 73 and 105 respectively, you must set them again using the correct values from Lyngsoe’s database. Troubleshooting 7-3 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. After the power-on test is finished, the sign-on message is displayed on the PC, but the DATA LED is flashing continuously at a random rate. 1. Check whether the Reader is receiving An improper carrier information that has been accidentally threshold was set, or there is transmitted from other Transponders in its an unwanted transmission on vicinity. If you eliminate the unwanted the UHF channel. transmission, the DATA LED will stop flickering. 2. Check whether an Exciter’s Test Tag is transmitting accidentally. 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 5-15. Step 2 - Set up the Carrier Threshold for the Reader. 4. If the Reader reports a channel noise level below -95dBm, but you are still not receiving the Transponders’ messages, check the noise level reported by the Reader with and without UHF antennas connected. If the noise level is identical or varies slightly (±1 dBm), replace the Reader. 5. If the Reader reports a noise level (HNL) above -95 dBm, the unwanted transmission is on the UHF channel. For procedures on eliminating the unwanted transmission, refer to Chapter 4, Setup Guidelines in the 95 Series RFID System Technical Guide. 7-4 Troubleshooting 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. If you can receive transmitted messages from the TST95, the Transponders are either not correctly configured for your application, or they are out of specifications. Reprogram the Transponders and check whether the Reader can receive messages. 3. If you cannot receive transmitted messages from the TST95, the Reader has an incorrect configuration. Go to Steps 4 and 5. 4. Check whether the DAR parameter and the Group R parameters are set according to the application’s specifications. 5. With this new set of parameters, check whether the Reader can receive transmitted messages from the TST95. If the Reader can receive the messages, save its configuration, by typing the following commands and pressing after each command: :CONFIG:STORE, :RESET. After the power-on test is finished, the sign-on message is displayed on the PC, but the DATA LED is not flashing when a Transponder is activated. 1. Run the procedure, S21 RFID System Final Test on page 5-15. Step 2 - Set up the Carrier Threshold for the Reader. The carrier threshold value is 2. If the Reader reports a channel noise level below -95dBm, but you are still not too high. receiving the Transponders’ messages, check the noise level reported by the Reader with and without connected UHF antennas. If the noise level is identical or varies slightly (±1 dBm), replace the Reader. 3. Check the HNL and RSS parameter values. Troubleshooting 7-5 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. Run the procedure, Setting Up the Carrier Threshold again, and monitor the value for the HNL parameter after each setup. 7. For procedures on eliminating the unwanted transmission, refer to Chapter 4, Setup Guidelines in the 95 Series RFID System Technical Guide. Reader does not record all transmitted messages. Reader does not record all transmitted messages by the Transponder. The receiving zone is too small because of either a high carrier threshold, or there is random interference on the UHF channel. 1. Run the procedure, S21 RFID System Final Test on page 5-15. 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 95 Series RFID System 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 7-6 Troubleshooting 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. 1. Query the Test Tag programming parameters using :TAG:QUERY:EXCITER k. 2. Check the value of all group T parameters. 3. Correct the values using the group W parameters. 4. Reprogram the Test TAg using the command :TAG:MATCH:EXCITER k. DATA LED is flickering, but the Reader’s Tag Record Buffer is empty. Test tag was incorrectly programmed. 1. Query the Test Tag programming parameters using :TAG:QUERY:EXCITER k. 2. Check the value of all group T parameters. 3. Correct the values using the group W parameters. 4. Reprogram the Test Tag using the command :TAG:MATCH:EXCITER k. DATA LED is not flickering Exciter’s Test Tag is placed beyond the limits of the receiving zone, or there is a random interference on the UHF channel, or the Test Tag is out of specifications. 1. Run the procedure, S21 RFID System Final Test on page 5-15. 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. Troubleshooting 7-7 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. Check whether the recommended setup guidelines for the Exciter’s location are met. Pay special attention to metallic surfaces surrounding the Exciter, shortcircuit loops, and the spacing between adjacent Exciters. The Exciter responds with C9 at the Self-Diagnostic Procedure. Exciter k responds with C9 at the command: :TEST:EXCITER k sent by the Main PC (k is the Exciter’s address). A faulty Exciter or a loose connection in the power cable or communication cable between the Reader and the Exciter. 1. Check the power cable and the communication cable between the Reader and the Exciter. 2. Check the Exciter’s address setting. 3. Check the LF Transmitter’s output. (See LF Antenna Connections on page 3-3). A large magnetic coupling between 2 adjacent Exciter EX21 frames 1. Check the Exciter’s TAP voltage. (See LF Transmitter Output on page 5-7). 2. Reposition the EX21 frames to minimize the unwanted modulation; the amplitude of VTAPmin> 60 Vpp. 1. Check the Exciter’s VTAP. The LF antenna is detuned by metallic objects that are in close proximity. 2. Reposition the EX21 frames to minimize the detuning; the amplitude of VTAP> 80 Vpp. 7-8 Troubleshooting Chapter 8 Drawings Overview This chapter contains drawings for the following: • • • Lyngsoe Industries Reader RD21 (600002) Lyngsoe Industries Exciter EX21 (600003) Lyngsoe Industries TRM95 Power Supply (600579) & (600626) -1 -2 ITEM QTY {247.0[9.7]} {420.0[16.5]Approx.} DESCRIPTION R21 MODULE 433 MHZ ANTENNA ENCLOSURE - BASE & LID SCREW - 6/32 X 1/4" SCREW - 6/32 X 3/8" CABLE RF ASSEMBLY Lyngsoe Industries PART NO: 500020 350873 400847 400561 400562 500053 {100.0[3.937]} 17 16 15 14 13 12 11 10 Item -3 LI P/N Part Description 400640 Mech Part 1" Sq.

It has 1 byte if HF=N and 2 bytes if HF=Y. = 1 byte message key; transmitted only if EN=Y. The parameters that control the message transmission for PT21 are shown in the table below: Range 3,4 Y/N Y/N Y/N 0...200 1...200 Y/N 0...255 0...255 1...220 Y/N Y/N Y/N Description Data rate; DR3 = 19.2 kbps, DR4= 38.4 kbps Standard error check transmitted Data encryption available Flags in hexadecimal Initial delay Initial number of messages transmitted after a valid execution Limit repeated transmissions Number of extra messages transmitted after IP during a continuous excitation Random seed Subsequent delay Synchronous preamble transmitted Transmit Flags Transmit System Code 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. 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. Transponder PT21 Messages B-1 Message Format The following is the method of evaluating the maximum transmission time for the PT21: Number of bytes per message: TXBytes = SC + UD + CRC + Flag + Key Number of bits per byte: BitsPerByte = 12 for DR4, and = 11 for DR3 Number of bits per message: TXBits = Sync + BitsPerByte*TXBytes Bit duration: BitLen = 1/DR Message length: MsLen = 0.0007 +TXBit*BitLen Intermessage constant: InterMsgUnit = (UD + Flag)*0.0003066, for DR4; (UD + Flag)*0.0005657), for DR3 Intermessage delay: InterMsgDelay = [SD +RND(0…31)]*InterMsgUnit; (RND - random value) Maximum number of transmitted messages: NM = IP +RC; if LT = N 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.

C-2 Excitation Modes 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. Setting the Reader’s Address to 0 2. Saving parameters: HV0, HV1, ISC, ISN 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: HV0, HV1, ISC, ISN 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 5-14. 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: 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. For example, for an IPC installation, write down the values for the following parameters: DCI, DRI, HTL, RCC, RSS. 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 95 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 5-3. If the Reader did not reset properly and did not send a sign-on message, then switch the Reader’s power supply Off and then On. 6. To verify whether the upgrade process was successful, type the following command: IVN D-2 Reader Software Upgrade Procedure 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. 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: 2. TX+; B TX+;Y To upgrade theAReader’s software, followRX+; steps ZStepsRX-. 2 - 5 in Using the RS232 Interface above. Reader Software Upgrade Procedure D-3 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. b) If the Reader was already configured on the site, you have to restore all application parameters queried during the Saving Parametersstep, or restart the configuration process as described in Chapter 5, Configuration and Operation. 3. Check the values of the new parameters that were introduced by this software version. For example, For an IPC installation, the following parameters must have the default values as follows: HCC=8, HCS=7, HE0=18, HE1=6, RCS=Y, RES=Y, SFC=N Setting the Reader’s Network Configuration To set the Reader’s network configuration, do the following: 1. Set the Reader’s address to it 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. D-4 Reader Software Upgrade Procedure 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.
