1.0 INTRODUCTION
This document provides the procedures required to install the TPRO7100 and the TPRO7200
readers. The installer should carefully read the section entitled “Effects Of Noise In The
Installation Environment” to gain an understanding of the environmental factors which may affect
system performance prior to attempting the installation. Techniques for reducing negative
environmental effects are also discussed in this section. The possible sources of interference for
an RFID system are similar to a standard Electronic Article Surveillance (EAS) system. One key
improvement is that the system has been designed to be immune to resonances and false alarms.
1.1 OPERATIONAL OVERVIEW OF THE TPRO7100 AND TPRO7200
The TPRO7100 and TPRO7200’s function is to read RFID tags which contain product
information. The TPROs read RFID tag data within twelve inches above the reader’s
surface.
The TPRO7100 consists of a TR4090 transceiver board and an antenna whereas the
TPRO7200 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 information
by tuning and detuning its resonant circuit. When tuned, the tag loads the reader antenna
which causes small amplitude perturbations of the reader field. The transceiver receives
this 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 its
serial port to a host PC.
In a TPRO7200, , the TR4090 converts tag data to ASCII and transmits this data over its
serial port to the SBC. The SBC in turn sends the data to a server over a 10base-T
Ethernet link. In addition to the RS-232 communications to the TR4090, the SBC
provides 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 is
read by the TPRO7200.
1.2 SYSTEM CONFIGURATION
The TPROs consist of as many as 5 major components. These are:
1. Antenna
2. TR4090 transceiver board
3. Power Supply (External wall pack)
4. Single Board Computer (TPRO7200 only)
5. Bar Code Scanner (TPRO7200 only)

2.0 EFFECTS OF NOISE IN THE INSTALLATION ENVIRONMENT
The following discussion on noise sources and the effects of noise on the system are provided
primarily to make the installer of the system aware of potential pitfalls when installing the
TPRO7100 or TPRO7200 equipment. However, the TPRO7100/7200 antenna is designed in
such 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 the
performance unless placed directly on top of the reader antenna section.
2.1 EFFECTS OF NOISE ON THE TPRO7100 AND TPRO7200 SYSTEM
The TPRO7100/7200 "listens" for very small field disturbances caused by the presence of
a tag. Since these signals are very small, it is possible to drown these signals in noise
produced by different types of equipment or noise produced by metallic objects in the
immediate 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 SOURCES
In the typical field environment, different noise sources will be encountered. Devices
such as electric motors, transformers, electric lines, etc., radiate alternating magnetic
fields. 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, they
will be "excited" by the system’s transmitted field. This will create noise in the system’s
antenna if the metallic object(s) is being mechanically or acoustically vibrated. As
opposed to the previously described active noise sources, these objects only re-radiate the
system’s signal and are therefore called "passive noise sources". This reflected noise
impairs the system’s sensitivity and may cause the system to miss a tag detection
opportunity.
Provided the mechanism that causes the disturbances are understood and that one is
familiar with the type of equipment / objects that cause these problems, it is quite simple
to avoid these pitfalls.
2.3 TYPICAL ACTIVE NOISE SOURCES
Provided that the distances between the system and the possible noise source(s) indicated
above are maintained, no special problems should be encountered.
The types of equipment typically responsible for system disturbances in a field
environment 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 the
antenna.
• Cash registers within approximately 3 feet (1 meter) from the antenna.
• Neon signs or fluorescent tubes within approximately 3 feet (1 meter) from the
antenna.

2.4 Passive Noise Sources
Passive noise sources can cause decreased sensitivity and lead to poor metal
discrimination and ultimately false alarms. Metal objects cause this. A few typical
examples 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-INSTALLATION
The following items should be checked by the CSE prior to installation. Careful attention to these
tips 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. The
system should be electrically connected to a dedicated AC line. No other device should be
connected at this point in order to diminish the risk of poor performance. An AC filter is
supplied in the power supply to help alleviate this problem and to ensure the unit complies
with EMC standards for both conducted immunity and conducted emissions.

1. Attach your SMB to BNC cable to TP1 on the TR4090 board.
2. 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 SERVICE
7.1 MAINTENANCE
No routine maintenance is necessary on this system though the system should be tested
periodically to ensure it is in safe working condition and that performance requirements
are satisfactory.
7.2 TROUBLESHOOTING
1. System does not work:
Check the fuse on the TR4090 indie the TPRO7100 or TPRO7200 and try again
2. No field is being generated:
Verify that the TR4090 is getting 12 volts
3. No baseband signals are visible at TP1 on the TR4090:
Replace the TR4090 board
4. 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 cash
register 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 the
problem. 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)

11.0 TPRO7100 And TPRO7200 Antenna Tuning Procedure
Tuning the TPRO7100 and TPRO7200 antenna involves adjusting a piston capacitor on the
antenna.
1. Supply power to the TPRO7100 or TPRO7200 using the appropriate wall pack.
2. Adjust the piston capacitor to maximize the distance from the antenna that the tag reads. You
will know that a tag has been read when you see the red LED on the side of the reader blink.
This distance should be > 8 inches when the tag is parallel to the antenna (you should be able
to adjust for at least a 10 inch read range).
