Document type: Title: Revision date: Revision: User's Manual (MUT) Mod. A528 OEM UHF Multiregional compact reader 02/04/2008 2 1. Introduction The A528 is an OEM UHF multiregional compact reader for integration into label printers, label applicators, handheld devices and in general any fixed or mobile short and medium range device requiring UHF tag programming and reading. The A528 can operate in both European (ETSI EN 302 208) and US (FCC part 15) regulatory environments and is fully programmable up to 500 mW conducted power. The reader supports EPC Class1 Gen2 protocol. The module uses the Intel® UHF RFID Transceiver R1000 and features a Gen2 Dense Reader Mode capability. Due to its multiregional capabilities the A528 is ideal for integration in devices requiring compliance to different geographic regions. A service board (Mod. A528ADAT), which allows to manage the A528 via USB and RS232, is available. Fig. 1-1: Mod.

Power supply connection In the following schematic suggested A528 power supply connection is shown. The use of fuse F1 is recommended since A528 doesn't provide internal current limitation protection. Diode D1 avoid damage to the reader in case of reverse polarity connection. The use of optional LC filter improves reader immunity in presence of noisy power supply. In order to ensure the correct operation of the reader the power supply shall not enter in burst mode (switching frequency less than 100kHz) when A528 reader is in idle mode (supply current less than 0.2A). As a rule of thumb the power adapter shall have a maximum current rating from 1A to 1.5A. Fig. 2-2: Mod. A528 power supply connection 2.2.4. General purpose I/O connections The GPIO0-GPIO3 pins are 4 general-purpose bidirectional pins. Their default direction after a power on reset or a general reset is set to Output. GPIO, when configured as Outputs, can be used to drive indicators as leds or buzzers or to send trigger signal to others equipments. GPIO, when configured as Inputs, can accept control signals from other equipments or trigger signals from sensors (i.e. photocells). In the following schematic an example of application of GPIO is shown. NPO: Filename: Number of pages: Page: 00101/07:A528X.MUTx/02 A528_REV02.DOC 19 10

Document type: Title: Revision date: Revision: User's Manual (MUT) Mod. A528 OEM UHF Multiregional compact reader 02/04/2008 2 2.5.1. A528 USB Recovery/FW upgrade USB upgrade is based on Atmel Smart Arm Microcontroller Boot Assistant (hence forth referred to as “SAM-BA”). The SAM-BA tools is distributed by Atmel via http://www.atmel.com/dyn/products/tools_card.asp?tool_id=3883 (download and install AT91-ISP.exe file). USB upgrade requires the following steps: 1. With power supply disconnected, connect with a short circuit J1 pin 4 (GPIO4) and TP1 pad. 2. With short circuit inserted connect the power supply to the board and wait for 5 seconds at least. 3. Disconnect the power supply. 4. Remove the short circuit between pin 4 of J1 and TP1. 5. Connect the power supply and the USB cable to A528ADAT. 6. At this point, Windows XP will detect the platform (in SAM-BA mode) and display the “Found New Hardware Wizard”. 7. The first screen asks if Windows can connect to Windows Update to search for the software, select: “No, not this time” and then click the NEXT button. 8. On the next wizard screen, select: “Install the software automatically”, then click the NEXT button. 9. A dialog will popup indicating that the driver has not passed “Windows Logo Testing”, click the “CONTINUE ANYWAY” button. 10. When the last screen appears, click the “Finish” button to dismiss the New Hardware Wizard 11. Reboot PC when prompted. 12. Run the SAM-BA v2.6 application on the WinXP host machine 13. When a dialog box appears, ensure AT91SAM7S256-EK is selected in the drop down list then click on the "USB connection" button. Note that a number of the names in the dropdown list are similar so ensure you select the correct one. 14. Ensure the "FLASH" tab is selected. 15. Enter the path in the "Send File Name:" or use the corresponding "Browse" button to find and select the file containing the new firmware. Latest release can be downloaded from CAEN RFID website (http://www.caen.it/rfid) 16. Click the "Send File" button. 17. Click "Yes" in response to "Do you want to unlock involved lock region(s)". Click "No" in response to "Do you want to lock involved lock region(s)". Finally - confirm the programming by clicking the "Compare sent file with memory" button. When SAM-BA reports that the files are identical click the “OK” button. 18. Exit the SAM-BA application via the File -> Quit option. 19. To ensure correct behaviour of Windows XP, click the “Safely Remove Hardware” icon in the Windows system tray, and Stop the Atmel Test Board entry and power DOWN your A528ADAT (disconnect power supply) NPO: Filename: Number of pages: Page: 00101/07:A528X.MUTx/02 A528_REV02.DOC 19 17

A528 RS232 FW upgrade To perform the FW upgrade via RS-232 interface these steps shall be followed: 1. Turn off the reader 2. Connect the reader with the RS232 serial cable to your PC using the adapter board A528ADAT. 3. Setup a serial terminal (such hyperterminal available on all windows OS) with the following settings: - baud rate: 115200 - data bits: 8 - parity: none - stop bits: 1 - Flow control: None 4. Turn on the reader. If A528 is configured to use INTEL protocol a boot message (see Fig. 2-8 ) will appear press the space bar within 6 seconds from boot. Fig. 2-8: Mod. A528 debug shell window If A528 is configured to use CAEN protocol no boot message will appear: in this case you shall type quickly and in capital letters the word “CAEN”. 5. After that in both cases a prompt ">" should be displayed. The reader is waiting for commands to be sent over the serial port. 6. Type "upgrade", press return and disconnect the serial port NPO: Filename: Number of pages: Page: 00101/07:A528X.MUTx/02 A528_REV02.DOC 19 18

Launch the upgrade tool (AT91SAM7SERIALBOOT.exe) provided into CAEN SDK CD-ROM on your PC. 8. Select the COM port you are using (typically is COM1) with the radio button on the left of the main window and press the connect button. 9. Click the Open button and Browse until you find the .bin firmware upgrade image 10. Press the Download button. If, for any reason, the upgrade procedure fails, do not power off the reader but press the download button again. 11. At the end power off the reader and power it on again. Firmware upgrade has been completed. If some problems occur in this procedure the recovery of module operation can be obtained by performing the procedure described in § 2.5.1. 2.5.3. Regulatory Compliance (FCC) This equipment has been tested and found to comply with Part 15 of the FCC Rules. NOTE: (a) Any changes or modification not approved by CAEN RFID could void the user’s authority to operate the equipment. (b) The A528 Module, which is rated at 500 mW output, are approved for operation with the CAENRFID antenna Mod. WANTENNAX010 (Linear polarized 3dBi gain 915 MHz PIFA antenna). Use of other than the approved antenna with this unit may result in harmful interference with other users, and cause the unit to fail to meet regulatory requirements. Professional installation is required for A528 Module. NPO: Filename: Number of pages: Page: 00101/07:A528X.MUTx/02 A528_REV02.DOC 19 19
