1. INTRODUCTION
The Avante SMART-TRAKKER™ Model SR3002 RFID Long Range Reader was designed to
communicate with Avante SmartTag® RFID tags based on the ICODE IC. Read/write functionality
and methods to use the anticollision capability of ICODE are included.
The primary focus is on the long-range capability, which makes the reader suitable for gate antennas
and tunnel applications.

2. SYSTEM HARDWARE
2.1 OVERVIEW
The SMART-TRAKKER™ in a complete RFID system:
2.2 SMART-TAGS®
The SMART-TRAKKER™ can communicate with the ICODE IC in any Avante I-code Smart-Tag
2.3 HOST
Any PC or Laptop computer running Windows 95/98/2000/XP Operating System with the Smart-
Trakker™ Software installed and having an RS232 serial port will serve as the host.
2.4 I/O PORTS
The Smart-Trakker microcontroller board has 6 input ports, 4 output ports and one EAS signal
output port all software addressable. The ports are not ESD protected, since they are not fed through
the metal housing. The data transmission connection between the Smart-Trakker™ and the Host
computer is through an RS232 serial port and cable. See the section on Reader to Host Protocol for
the communication protocol

2.5 ANTENNA
Any Avante Smart-Trakker™ 50-ohm antenna designed for the reader can be used. A 50-ohm
coaxial cable terminating in a 50-ohm BNC connector transmits data from the antenna to the reader
2.6 POWER SUPPLY
A linear regulated power supply of 24 VDC at a maximum of 2.0A is included.

3. DESCRIPTION
3.1 BLOCK DIAGRAM
See Attachment.
3.1.1 Power Supply
Generates 24 VDC power from 120 VAC line voltage.
3.1.2 Voltage Regulation
Generates all necessary voltages for the Smart-Trakker from the 24 VDC power supply voltage.
3.1.3 Clock Generator
Generates the 13.56 MHz clock for the transmitter amplifier. A divided clock signal synchronizes
the microcontroller.
3.1.4 Modulator, Transmitter Amplifier
Modulates the carrier with a digital signal from the microcontroller for data transmission. The
Transmitter Amplifier amplifies the modulated carrier.
3.1.5 Modulation Index, RF Power Regulation
Keeps the Antenna Output Voltage to a software adjustable value. The Modulation Index is
software adjusted after any change in the RF-output power and at large temperature variations.
3.1.6 Receiver, Filter, Demodulator and ADC
The SmartTag IC sends an AM signal. This signal is converted for digital processing by the 12-bit
ADC after filtering, demodulation, and amplification.
3.1.7 Optocouplers
All internal signals are galvanically decoupled by optocouplers.

3.1.7 Microcontroller
Processes the communication protocol between the SmartTag IC and the Smart-Trakker reader. The
serial interface signals are converted so that the tag IC can process them and signals from the tag are
converted to serial interface compatible signals.
3.1.8 RS232 Interface
Communication to the host is via a serial interface with a jumper selectable baud rate of 57.6 or
115.2 kbaud.

5. TROUBLESHOOTING
For any problems (reduced communication distances, errors or failures), check the following list:
• Power at the outlet source.
• Power supply cable not properly plugged in to the power supply or loose.
• Serial interface cable not plugged in or loose.
• Serial interface cable, power supply cord or antenna cable are too close to the antenna.
• Interference to the antenna from an external source.
• Antenna mounted on or too close to a metal environment.

6. OPERATING CONSIDERATIONS
6.1 SUPPLY VOLTAGE
The Smart-Trakker Reader is protected against supply peaks and incorrect polarity for short periods
of time. Longer periods of out-of-spec supply power will result in permanent damage to the reader.
6.2 ANTENNA OPENS OR SHORTS
The Smart-Trakker can withstand short periods of open circuit or shorting at the antenna. Permanent
damage will result from a longer uncorrected fault.
