1 Scope
Radio Frequency Identification (RFID) has been included in the 21st century
one of the 10 major technologies. RF is the automatic identification object
recognition technology. Readers are to read in the attached electronic tags on
objects such as to carry out card access to the information, animal tracking,
checking inventory and merchandise checkout, and sales of the whole supply chain
management. This will become a model to change human consumption patterns
emerging technology.
The main operation principle of RFID is utilizing the reading device (Reader)
Send RF wave for the electronic label that is planted into or stuck on the things
(Tag) in order to distinguish the wireless materials. The composition component of
RFID system includes Reader, Tag, PAD or cell-phone and the contents which are
in reader or tag.
When the application system wants to distinguishing things, the host can be
passed by RS-232 to control reader and sends radio wave energy. When Tag senses
this energy that there is asking the answering machine inside (Transponder) and the
mechanism will change power into energy that passes a series of discernment
materials giving back to reader and host that are in order to distinguish the things.
The specification of ART-320 is in compliance with EPC Class-1 Gen 2 that
is a specification for RFID air interface.
The changes or modifications not expressly approved by the party responsible
for compliance could void the user’s authority to operate the equipment.
Note: This equipment has been tested and found to comply with the limits for
a Class B Digital Device, pursuant to part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the instruction,
may cause harmful interference to radio communication. However, there is no
grantee that interference will not occur in a particular installation. If this equipment
dose cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on , the user is encouraged to try to
correct the interference by one or more of the following measures:
--Reorient or relocate the receiving antenna.

4 System Specification
Reader is mainly used to read the materials from tag to carry on the work of
distinguishing of the things with PDA or the cell-phone. When PDA or the
cell-phone assigns the order for Reader, reader will transmit RF wave with data out
through antenna. Once tags are receiving the information, the tag will backscatter
the data with 96-bit EPC C1G2 protocol to Reader through RF mechanism that is
built inside. Reader receives after the data that will give PDA or the cell-phone the
work of distinguishing which carries on the things.
For the wired RS232 interface of entity among PDA, cell-phone and readers,
the industrial communication protocols are interchanging in order to reach the data.
It is depending on the untouchable RF wave between reader and tag to reach the
data to interchange with the communication protocol that is defined by EPC
C1G2。
The Fig 4-1 is a data flow chart. It is including Reader, PDA and cell-phone
communication code of protocol during the encoding and decoding. The code of
the communication protocol between Reader and Tag is operated with decoding.。

4.1.1 Radio Frequency Circuit
This is a transceiver module with ISM of the electromagnetic wave for a
transmission and receiving. It is among them transceiver inside that is in transmitter
and the receiver function as follows:
The function of the Transmitter:
The function of the transmitter is controlled and produced the signal
carrier by the synthesizer of the microprocessor. The signal that will be
modulated in amplitude to be an ASK signal used to offer the power that
the tag is used to read data from its memory as well as using the pulse to
adjust the way of changing to write the data into the tag。
The function of the Receiver:
The function in receiving information from tags has been demodulated to
several digital signals. The signals are also amplified and straining waves
to deal with microprocessor.

4.1.3 Hardware User Manual
The ART-320 connects to the host via a 16 pins header for data,
communications and 4-pin header for power. The 3 data lines are: Ground, Data
Transmit (TX) and Data receive (RX) for UART. The communication header also
contains the additional pins which are interfaces for JTAG. Those pins can be used
to provide data to another sensor or auxiliary board. The power header pins
supplying power to the ART-320 is 3.3 Volts (and must be low-noise and
regulated). A diagram of the pins are given below.

4.1.4 Module Operation
The ART-320 is a dual-antenna reader module. The backscatter signal is
demodulated to baseband through a standard mixer stage and is filtered and
amplified. The baseband signal is then sampled and processed by a microcontroller.
The entire RF section of the reader module can be completely turned OFF under
software control by the microcontroller. This allows the ART-320 to consume
very low power when in standby mode. During RFID operation, the transmit
power of the ART-320 is 1W, so the total power consumption is 1.8A during the

4.1.5 Interfacing with ART-320
The ART-320 is designed to interface with another circuit board and communicate
using a simple 3-wire serial interface. However, for testing purposes, it is possible
to connect the ART-320 to a computer using a serial RS-232 adapter. In this case,
the Advantech RFID Utility software can be used.

4.1.6 Starting Windows Demo Program
After installing the demo program, you can connect the reader to the computer
using a serial cable (standard DB9 connectors). Please make sure that you have an
antenna connected to the reader.
The program supplied with the kit is able to interface to all the RFID readers made
by Advantech. You should open the program (Advantech RFID Utility), then go to
the Inventory menu and selected . Then go to the Connection menu and select the
proper COM port where you connected the reader, you can click the CONNECT
button. After you run the program for the first time, the software settings will be
saved automatically so you should not need to reconfigure the control program
unless you switch to another reader product.
