Introduction This document describes the architecture important functions. For a complete reference of implemented functions please refer to the Doxygen documentation. Application Layer After connecting the reader to the computer the reader is automatically installed as a HID (Human Interface Device). The USB HID protocol defines different reports. Every report starts with its own report ID defining the length and if it is an incoming or an outgoing report. USB Report-Frame Each report frame starts with a Report ID byte. The second byte defines the length of the frame (the ID and the length bytes are included in the length). Byte 1 Byte 2 Variable length Report ID Frame Length Payload Table 2 Report Frame USB Reports The following table gives an overview of the implemented USB reports. Each USB report causes the device to reply with a response frame (incoming report).

Copyright by Arygon Technologies AG - 2011 Page 22 of 28 Before calling any of the functions the AUDR UHF reader chip needs to be initialized using AUDR UHF readerInitialize(). Next the function gen2Open() needs to be called for opening a session. gen2SearchForTags() should be called to identify the tags in reach. Typically tag singulation is done next. In order to do so gen2SearchForTags() is called again provided a proper mask to singulate (select) a tag. In this case only one tag is returned by gen2SearchForTags(). This tag is then in the Open/Secured state and may be accessed using the other Gen2 functions (gen2WriteWordToTag(), gen2ReadFromTag(), ...). When finished with gen2 operations this session should be closed using gen2Close().

Per default it loads the European frequency setup upon start up. Different setup can be applying the commands described in tables 18 – 25. Nevertheless the default function implemented in firmware after loading the region specific frequencies is as follows. ARYGON Reader Suite GUI is designed to allow most freedom in select different adoptions in the worldwide setup. Picture 6 – Parameters

Copyright by Arygon Technologies AG - 2011 Page 27 of 28 In the frequency section e.g. USA settings: Each setting can also be manually changed upon user requirements. The selection of a profile will load region specific settings for: Start frequency: The lowest channel frequency End frequency: the highest channel frequency Increment: The channel spacing between two channels RSSSI Threshold: give the opportunity to set a Listen before Talk (LBT) value. In case a LBT is not needed or not wanted, this level should be as high as possible ( e.g. -40 dB) The thresholds that can be managed by the system starts at -47 dBm and can reach up to -86 dBm. (Please note that the levels are chip values and can be changed by the external components. That means that Arygon will have a 10 dB higher value than the described value in the GUI) Listen time: This time specify how long the reader is listening to the channel. The largest recorded signal during the listen time will determine the channel power. Idle time: This time specify the time between two channel hop. Maximum allocation time: This time define the maximum time on one frequency. The profile will be transferred with the “Set” Button to the reader. After press the button, the GUI will start to transfer a randomized frequency table List and store it in its memory. Now the reader will change the frequency on every Inventory or Tag command according to the list. Since the Gen2 anti collision round is limited by the slot counter Q, it is possible to calculate the maximum allocated channel time to less than 400ms. Nevertheless it is also possible to limit the channel allocation time with the maximum allocation time. Since Arygon is used as a desktop reader, the user is advised to use a max Q value of less than 4. The Gen2 settings are for individual Link frequencies. For USA, it is recommended Link frequency: 256 kHz Session:S0 Q_Begin: 4

Firmware update of the AUxx reader Assuming that the boot loader is already loaded into the flash memory the firmware of the AUxx reader system can be updated in an easy way. Care needs to be taken that the ARYGON Reader Suite is not running at the same time during the programming process. To program the AUxx UHF reader system simply double click the batch file “FWupdate_ARYGON_UHF_reader.bat”. The batch file will run the “up.exe” executable which loads the “Arygon.bin” into the micro AUDR‘s flash memory. Therefore those two files need to be present in the same directory as the batch file itself. When the programming is completed the message “Successfully written xxxx bytes” appears. Hit any key to close the window and return to WINDOWS. Picture 7: Firmware updating response The Arygon readers are now able to communicate with the ARYGON Reader Suite via USB.
