Software Installation

The ATAK2270 host installation software as well as the related datasheets and documentation are pro-

vided by the CD-ROM included in the kit. Furthermore, the up-to-date software and documentation are

available via the web.

Execute the setup.exe file found on the CD-ROM to launch the installation and generate the

ATAK2270.exe program file. If the default settings are accepted during installation, the program file will

be installed to path: X:\Programme\ATAK2270\ATAK2270.exe.

Note:

Administrator rights are required to install this software.

2.2.1

AVR Programming Guide

The AVR base board (Figure 2-3) is equipped with two programming interfaces, ISP and JTAG allowing

reprogramming or updating the firmware of AVR flash memory.

ISP is a downloading method. Only six I/O lines are needed. The provided header works with the

ATSTK500 as well as the AVR ISP In-System Programmer. Both of these are available from Atmel or

distributors for very low cost program development. To program the flash memory and the EEPROM,

first connect the programming tool to the MB using a six-pin ribbon connector. Make sure that proper ori-

entation is maintained by aligning pin1. The files types accepted use Intel Hex format.

To program a hex file into the target AVR device, select “Program AVR” and then “Connect...” from the

“Tools” menu in AVR Studio. Once AVR Studio has been opened, connect to the STK500 or AVRISP by

selecting “STK500 or AVRISP” in the Platform List. Then select “Connect...”. The driver for the STK500

and AVRISP is then started, and the STK500 dialog should appear. Note that the system supports other

programming platforms as well, like the JTAGICE or the JTAGICE mkII.

Then select the AVR target device from the pull-down menu on the “Program” tab and locate the Intel-

hex file to download. Select the “program” button. Repeat for the EEPROM section.

The same steps apply when using the JTAGICE MKII.

The JTAG Platform allows more control during software development by allowing real-time debugging of

the source code. The JTAGICE MKII supports setting breakpoints and stepping through the code being

executed on the target micro. This is very useful for a more complex software project such as this one.

Fuse Settings:

Fuse bits must be set properly for the kit to function. The only fuse bits that should be set are listed

below.

„ JTAG Interface Enabled; (JTAGEN = 0)

„ Serial program downloading (SPI) enabled; (SPIEN = 0)

„ Boot Flash section size = 512 words Boot start address = $FE00; (BOOTSZ = 11)

„ Brown-out detection level at VCC = 2.7V; (BODLEVEL = 1)

„ Int. RC OSC. 8MHz; Start-up time; 6CK + 64 ms; (CKSEL = 0100 SUT = 10)

All others should be unchecked.

Description of the Application Board System

3.1

System Overview

The ATAK2270 application board unit (Figure 2-3) consists of a ready-to-run standard microcontroller

main board equipped with the Atmel AVR^®microcontroller ATmega8515L, combined with a piggybacked

antenna interface board containing the U2270B reader IC.

The following functionality is controlled by the AVR microcontroller:

„ Handling of the bi-directional data communication between the RS232 interface and the host PC

„ Execution of the read and write commands to be sent to the antenna interface

„ Decoding of the specific read data delivered by the antenna interface

The source program is written in C, and the compiled hex code is loaded in the 8-kByte Flash of the

microcontroller.

3.2

3.3

Power Supply

To operate the reader board, an external power supply in the range of DC 10V to 15V/200 mA has to be

connected to the jack, alternatively use the mains SMPS. A bridge rectifier placed at the connector input

is used for polarity independence.

Antenna Interface

The antenna interface (Figure 2-2) is supplied and controlled by the main board via header pin X2/1. The

current power supply voltage is indicated by LED1, Power. To adapt a specific antenna coil to the reso-

nant frequency and the Q factor, the components CANT1/CANT2 and R14 (Figure 2-2) can be changed.

For the antenna included in the kit, the parameters are matched as follows:

Resonant frequency:

f_res= 125 kHz 1%, adjusted by CANT1/CANT2 with jumper 3 in

position dis

Whole antenna quality factor:

Q = 20, adjusted by R14

Frequency Tuning Mode Selection

The reader interface has a built-in frequency tuning feature. By the host software, the resonant fre-

quency of the LC antenna circuit can be switched in four steps. Therefore the board is equipped with two

stages of high-voltage transistor switches to tune the resonator via switched capacitors.

Table 3-1. The Frequency Tuning Can Be Selected Using Jumper J3

Tuning Mode

Disabled

Jumper J3 Position

1-2

2-3

Enabled

In default setting Tuning Mode is activated, allowing the adjusting of antenna frequency by host menu.

The binary control of the two tuning stages enables the selection of one out of four frequency states.

According to the menu definition the frequency steps are designated as follows:

High Frequency

134.2 kHz (acc. ISO11784/85)

Semi High Frequency

Semi Low Frequency

Low Frequency

130 kHz

125 kHz

121 kHz

In disabled mode, the interface operates with the fixed frequency adjusted typically to 125 kHz.

The currently selected frequency stage is displayed on the application board by the red LEDs Tune 1

and Tune 2 (shown in Figure 2-2, see Table 5-1 for interpretation).

3.3.2

T5557/ATA5567 Multifunction Read/Write Transponder

The ATA5567 offers an improvement over T5557’s slow power-on behavior. Apart from this difference,

both transponders are functionally identical and thus can be managed by same user interface. Both tran-

sponders are backward compatible to the older T5551/TK5551 version. Therefore, they can be operated

in the Compatible or Basic Mode.

For Compatible Mode refer to Section 5.3.3 ”TK5551 Read/Write Transponder” .

5.3.4.2 T5557/ATA5567 Extended Mode

In contrast to Compatible Mode, Extended Mode is enhanced by additional features, which can be

enabled. These include:

„ SST Sequence Start Marker

„ Inverse Data Mode

„ OTP General Data Protection

„ Enlarged Data Rates

„ Fast Write Mode

„ Traceability Manufacturer Data

Figure 5-15. Extended Mode Main Read Tab

Selecting Extended Mode displays the Read tab (Figure 5-15). The Read tab is divided into two areas –

Configuration Setup and Read Timings.

5.3.4.3 Configuration Setup

„ Bitrate: Rf / (n + 2) for n = 0 to 126 (default setting Rf/32)

„ Coding: Manchester, Biphase 1('50), Biphase 2 ('57), Direct, PSK..., FSK,...

(refer to the T5557 datasheet), (default = Manchester)

„ ID-Code Length: Block0, Block1, Block 1 to 2, Block 1 to 3, ..., Block 1 to 7 (default = Block 1 to 7)

„ Signature: 8-bit Header, Sequence Start Terminator (default = Header 6Eh)

„ Use 12-bit Header: RFID application complying to the ISO/IEC 11784/85 standard. For example, for

animal IDs, the 11-bit binary header 0000 0000 001(0) is used. For this reason, a three-nibble header

window is specified (default = 002h)

„ Password: Activates password mode used for protection against overwriting and Answer On Request

(AOR) Function (default = not activated)

„ Lock Block 0: Setting this bit locks the Configuration Block 0 of the transponder. Once the lock bit is

set, the bit rate, coding etc., are locked and cannot be changed. Use this feature with care.

„ Inverse Data: Data uplink is performed inversely when activated (default = not activated)

„ Answer On Request (AOR): Activates anticollision mode. (When this check box is selected, an

additional button appears for AOR wake-up.) (Not activated is the default.)

„ POR-Delay: In the default setting, the modulation starts after 192 clock cycles (1.5 ms at 125 kHz) are

recognized. When actively selecting POR-Delay, the modulation delay measures 8382 clock cycles

(67 ms at 125 kHz)

„ Fast Write: When Fast Write is selected, the write times in the Write menu are reduced by half

„ OTP: If OTP is set, all memory blocks are write-protected

These configuration parameters are sent to the transponder when the Configure Transponder button is

clicked. The transponder should be placed close to the reader antenna when this is at that time.

Note:

The base station IC U2270B does not support the reading of all bit rates and codings offered by the tran-

sponder type. If a non-supported mode is configured, a warning message will be displayed on the screen.

5.3.4.4 Data Read

When a read command is executed by clicking the Read button, the current Read Timing parameters,

among others, are sent to the microcontroller baseboard via the RS232 interface. The data stream com-

ing in from the antenna interface is analyzed in real time as specified by the timing definition. Afterwards,

the microcontroller transfers the decoded binary values to the host. Default timing settings are suitable

for the transponder samples contained in the kit. If a Header Signature is used, ensure that the related

Header has already been programmed into the transponder using the Write menu.

Note:

When reading a transponder, the specific programmed configuration has to be matched with settings on the

host menu, such as Bitrate, Coding, ID-Code Length, and Signature. If the configuration of the transponder

is unknown, a reconfiguration is needed.

Click the Default button to resets the default settings.

Click the Reset Command button to send the OP code 00 to the transponder. This initializes the Read

Mode operation.

The structure of the ATA5577 user interface differs from the other transponder types.

In the Setup window, four tabs – Transp. Settings, Write, Read and ISO 11784 – and the Downlink sec-

tion allow the configuration, reading, writing and programming and reading transponder according ISO

11784/85 standard.

5.3.6.2 Downlink Settings

The Downlink section, above the tabs, indicates the current downlink mode from the reader to the tran-

sponder. Downlink modes are selectable as follows:

„ Downlink Protocol

5.3.6.4 Selecting Write tab

Figure 5-22. ATA5577 Write Tab

In the Extended Mode, the Fast Write check box in the Downlink section is released (This is the only dif-

ference to the Write tap in Basic Mode).

However the Fast Write feature makes less sense for programming via resonating antenna coupling, due

to the needed time duration determined by the gap time of the ON/OFF Keying (OOK). Nevertheless, the

feature is performed by the software.

It may be worth considering for production programming transponders in Fast Mode by direct coupling or

by antennas with low Q factors. If the Fast Write is selected the default values of the Write Timing will be

reduced accordingly.

In the Write tab, the block data 1-7 and write timing text boxes are automatically populated with their

default values. If the Write check boxes are not selected, the blocks will not be written. If the Lock check

boxes are selected, the block will be permanently locked.

The data for each block is entered in hex. The blocks to be programmed are chosen by selecting the

check box in the Write column. To protect the data from being overwritten, select the Lock check box.

Once the lock bit is set, the information cannot be overwritten. Use this feature with care. Click the

Default button to restore the default settings. To exit the menu, click the Cancel button.

The default write timing set should be suitable for typical antenna with Q factors in low to medium range.

For special transponders, three ranges of antenna Q factors are selectable. According to Q selection,

the required write timing parameters are transferred to the timing window.

The synchronization of the transponder can be configured in the Synchronization area. (Terminator is

selected by default.) If Synchronization Bits is chosen, an 8 bit header can be entered. E6h is entered by

default in this field. An extended header can be configured by clicking the 12 Bit Header check box and

entering the longer header in either the Binary or Hex text field. For an ISO11784/85 transponder, the

default header 002h or 003h are needed.

Click the Read button to read the transponder block data as specified by the settings. The transponder

data is read only once. To read the transponder continually, select the Continuously Read check box. To

receive audible notification, select the Sound On check box. This indicates an incorrect or correct

reading.

To read a specific block from page 0 or page 1, click the Direct Access button. The Direct Access mes-

sage box is displayed, see Figure 5-24. Select the Page radio button, (Page 0 or Page 1), then select the
