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. Should there be any questions about this manual, please visit the user section of www.avantetech.
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 SmartTrakker™ Software installed and having an RS232 serial port will serve as the host. SR3002 2.
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.
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.

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.
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. User Manual Version 1.1.0 ©Avante International Technology, Inc.
