CONFIDENTIAL AND PROPRIETARY INFORMATION, FOR INTERNAL USE ONLY.Dwg. No. 813910 Rev. *60 Page 31.0 INTRODUCTIONThis document provides the procedures required to install the TPRO7100 and the TPRO7200readers. The installer should carefully read the section entitled “Effects Of Noise In TheInstallation Environment” to gain an understanding of the environmental factors which may affectsystem performance prior to attempting the installation. Techniques for reducing negativeenvironmental effects are also discussed in this section. The possible sources of interference foran RFID system are similar to a standard Electronic Article Surveillance (EAS) system. One keyimprovement is that the system has been designed to be immune to resonances and false alarms.1.1 OPERATIONAL OVERVIEW OF THE TPRO7100 AND TPRO7200The TPRO7100 and TPRO7200’s function is to read RFID tags which contain productinformation. The TPROs read RFID tag data within twelve inches above the reader’ssurface.The TPRO7100 consists of a TR4090 transceiver board and an antenna whereas theTPRO7200 is composed of a TR4090, a single board computer (SBC), and an antenna.The TR4090 continuously drives the antenna at a carrier frequency of 13.56MHz.The antenna field powers the RFID tag. Once the tag has power, it sends out informationby tuning and detuning its resonant circuit. When tuned, the tag loads the reader antennawhich causes small amplitude perturbations of the reader field. The transceiver receivesthis signal using AM detection, applies gain, and filters the signal.In a TPRO7100, the TR4090 converts tag data to ASCII and transmits this data over itsserial port to a host PC.In a TPRO7200, , the TR4090 converts tag data to ASCII and transmits this data over itsserial port to the SBC. The SBC in turn sends the data to a server over a 10base-TEthernet link. In addition to the RS-232 communications to the TR4090, the SBCprovides RS-232 communications to an external bar code scanner and a data terminal.The bar code scanner is used to enter information which is associated with tag data that isread by the TPRO7200.1.2 SYSTEM CONFIGURATIONThe TPROs consist of as many as 5 major components. These are:1. Antenna2. TR4090 transceiver board3. Power Supply (External wall pack)4. Single Board Computer (TPRO7200 only)5. Bar Code Scanner (TPRO7200 only)
INSTALLATION PROCEDURE,TPRO7100 AND TPRO7200____________________________________________________________________________________________________________________________CHECKPOINT SYSTEMS, INC. CONFIDENTIAL AND PROPRIETARY INFORMATION, FOR INTERNAL USE ONLY.Dwg. No. 813910 Rev. *60 Page 42.0 EFFECTS OF NOISE IN THE INSTALLATION ENVIRONMENTThe following discussion on noise sources and the effects of noise on the system are providedprimarily to make the installer of the system aware of potential pitfalls when installing theTPRO7100 or TPRO7200 equipment. However, the TPRO7100/7200 antenna is designed insuch a way that the reader can be placed on a metal counter without degradation of performance.For the same reason, passive noise sources in general should not be detrimental to theperformance unless placed directly on top of the reader antenna section.2.1 EFFECTS OF NOISE ON THE TPRO7100 AND TPRO7200 SYSTEMThe TPRO7100/7200 "listens" for very small field disturbances caused by the presence ofa tag. Since these signals are very small, it is possible to drown these signals in noiseproduced by different types of equipment or noise produced by metallic objects in theimmediate vicinity of the system’s antenna.Once it is understood what the typical problems are, the Customer Service Engineer (CSE)will find that avoiding these problems simplifies the installation process.2.2 TYPES OF NOISE SOURCESIn the typical field environment, different noise sources will be encountered. Devicessuch as electric motors, transformers, electric lines, etc., radiate alternating magneticfields. These devices will generally be referred to as "active sources".If metallic objects are within (to the sides and above) 1 foot of the system’s antenna, theywill be "excited" by the system’s transmitted field. This will create noise in the system’santenna if the metallic object(s) is being mechanically or acoustically vibrated. Asopposed to the previously described active noise sources, these objects only re-radiate thesystem’s signal and are therefore called "passive noise sources". This reflected noiseimpairs the system’s sensitivity and may cause the system to miss a tag detectionopportunity.Provided the mechanism that causes the disturbances are understood and that one isfamiliar with the type of equipment / objects that cause these problems, it is quite simpleto avoid these pitfalls.2.3 TYPICAL ACTIVE NOISE SOURCESProvided that the distances between the system and the possible noise source(s) indicatedabove are maintained, no special problems should be encountered.The types of equipment typically responsible for system disturbances in a fieldenvironment are:• Transformers or high current AC cables within 6 feet (2 meters) from the antenna.• Escalators within approximately 6 feet (2 meters) from the antenna.• Electronic equipment in general, within approximately 6 feet (2 meters) from theantenna.• Cash registers within approximately 3 feet (1 meter) from the antenna.• Neon signs or fluorescent tubes within approximately 3 feet (1 meter) from theantenna.

No. 813910 Rev. *60 Page 52.4 Passive Noise SourcesPassive noise sources can cause decreased sensitivity and lead to poor metaldiscrimination and ultimately false alarms. Metal objects cause this. A few typicalexamples of metal found near an RFID system include:• Frames in counters.• Metal objects that can be placed in a counter after installation.• Metal dust bins.• Metal displays.• Security gates, especially the closed loop sections.• Metal cabinets.• Door frames, especially closed loops.• Metal tubes/structures hidden in walls.• Metal structures on other side of wall (therefore not visible and uncontrollable).• Sheet metal surfaces.• Metal window frames, especially closed loops.3.0 PRE-INSTALLATIONThe following items should be checked by the CSE prior to installation. Careful attention to thesetips will minimize post installation issues.• A qualified technician should conduct a site survey before contracting and installation.• Quality of the AC ground can have considerable effect on the RFID system sensitivity. Thesystem should be electrically connected to a dedicated AC line. No other device should beconnected at this point in order to diminish the risk of poor performance. An AC filter issupplied in the power supply to help alleviate this problem and to ensure the unit complieswith EMC standards for both conducted immunity and conducted emissions.4.0 INSTALLATION4.1 SERVICE PERSONNELThis product should only be installed and serviced by personnel properly trained to:• Read wiring diagrams• Use electronic test equipment• Make electronic wiring connections• Use hand and small power tools• Fault find on live equipmentCAUTION: Installing this product involves working while AC power is on.

Set your scope to 100 mV vertical, 1 ms horizontal.3. The noise floor will typically be between 50 to 100 mVpp in a “clean” environment.4. The tag signal should always be at least twice the amplitude of the noise.5. See section 8 of this document for how the tag signature should look.7.0 SERVICE7.1 MAINTENANCENo routine maintenance is necessary on this system though the system should be testedperiodically to ensure it is in safe working condition and that performance requirementsare satisfactory.7.2 TROUBLESHOOTING1. System does not work:Check the fuse on the TR4090 indie the TPRO7100 or TPRO7200 and try again2. No field is being generated:Verify that the TR4090 is getting 12 volts3. No baseband signals are visible at TP1 on the TR4090:Replace the TR4090 board4. Noise Level:In a location with high levels of noise, always try to remoce the source of the noise first.For instance, if the noise-source is a cash register near the system, position the cashregister further away from the system’s antenna.5. Fuse on TR4090 keeps blowing:Replace with a fuse fo same type and rating. If it blows again, try to fault-find theproblem. If you can’t solve the problem, then replace the board at fault.6. Poor detection:Make sure the antenna is tuned (see section 12)7.3 SPARE PARTS FOR SERVICE• TR4090, Part # 109210• Single Board Computer, Part# 443702• TPRO7100/TPRO7200 wall pack, Part# 8566128.0 DIAGRAMSThis section includes wiring diagrams for the TPRO7100 and the TPRO7200 as well as a ‘scopeshot’ of the base band signal measured at TP1 of the TR4090. 8.1 TPRO7100 WIRING DIAGRAM
