User Manual Version 1.1.0 August 23, 2005 Page 4 ©Avante International Technology, Inc. 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.com or call the technical support center of Avante International Technology, Inc. 1-800-735-5040. Basic features of the SR-3002 Long Range Reader • 24VDC power supply input • 13.56 MHz carrier frequency • RS323 serial interface, 115.2 or 57.6 KBaud data rate • Regulated RF output power, software adjustable from 2 to 10 W @ 50 ohm • Software adjustable modulation index (10%-20%) • RS232 upgradable firmware • Anticollision capability • Standard and Fast Mode support • BAPT and FCC approval • CE compliant
User Manual Version 1.1.0 August 23, 2005 Page 5 ©Avante International Technology, Inc. 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 SR3002
User Manual Version 1.1.0 August 23, 2005 Page 6 ©Avante International Technology, Inc. 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.
User Manual Version 1.1.0 August 23, 2005 Page 7 ©Avante International Technology, Inc. 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.
User Manual Version 1.1.0 August 23, 2005 Page 8 ©Avante International Technology, Inc. 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.
User Manual Version 1.1.0 August 23, 2005 Page 9 ©Avante International Technology, Inc. 4. SPECIFICATIONS 4.1 ELECTRICAL 4.1.1 Power Supply The power supply supplies voltage with the following basic specifications. Although the circuit performs some filtering of the power supplied, the input power must meet some minimum ripple standards. Output Voltage +24 VDC Nominal Current 2 A Maximum Ripple freq. 50Hz to 10 MHz 100 mV max. Amp. 10 MHz to 20 MHz 50 mV max. Amp. 20 MHz + 100 mV max. Amp.

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.
User Manual Version 1.1.0 August 23, 2005 Page 15 ©Avante International Technology, Inc. 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.
