By software, use the IndyTool to turn on the GPIO settings. The General purpose GPIO can be configured as Input or Ouptut and the corresponding state is also reflected. The Refresh button can be used to update the states of the GPIOs configured as input. The greyed state boxes reflect the Input State. When configured as GPOs the state becomes user selectable. The ARM GPOs can be set Low and High via the ARM GPO control box.
12 Chapter 2 Introduction Overview The IndyTool is a .Net-based graphical user interface (GUI) tool that uses the Indy® RFID Host Library API to exercise the functionality of the reader platform, a platform that is based on the Indy chip and firmware. The IndyTool is dynamically linked to the Indy RFID Host Library. Therefore, there is no need to install the interface library separately. However, the USB / UART host driver must be installed prior to using IndyTool. IndyTool is supported on Windows XP only. The goal of this document is to explain the operation of the tool. This document does not explain the underlying RFID functionality that it is controlling via the Indy RFID Host Library API. Indy Tool General Usage General Guidelines  IndyTool will not modify the reader state without user intervention. The state of the reader is only affected when the user executes a function within the application.  Multiple instances of IndyTool can be opened concurrently, however only one reader in one instance can be connected at any one time.  All user input fields indicate the input type. The label (d) indicates a decimal input. The label(h) indicates a hexadecimal input is expected, and if any other characters are inputted they will be corrected by the application. Unless otherwise specified all the input fields in the GUI that are marked (h) do not require the 0x prefix.  All user commands are logged in the Status Window and will show continuous progress or show single command execution depending on the status options.  If a reader is disconnected or reset without using IndyTool, the application will show the last known state of the reader and on the next command attempt, the status will indicate the connection error. To recover, select disconnect, re-enumerate if necessary, and connect back to the reader. IndyTool for Configuration and Development
13  IndyTool can be connected and disconnected to and from a reader at any time. This will allow for a user to configure the reader, disconnect and subsequently run any other application to run the reader.  The target usage for IndyTool is for Engineering Development. The scope of this document is to describe the functions in IndyTool and is not meant to describe the MAC firmware fundamentals, which are a prerequisite to utilizing the system as a whole. IndyTool Main Window The following figure shows the main application window. Main Application Window On IndyTool startup, all the readers connected to the system via USB and the indicated COM port are auto-enumerated. The attached readers are indicated in the status window and a pull down list is populated from which to select. If there are no readers connected to the system, this will be displayed in the status window and there will no readers in the pull down menu. If there is a library exception when starting up the application or any other error, this will be indicated in the status window. Status Window The status window shows the outcome of a user command. All commands and functions will generate some form of feedback in this window. 1. Clear Button – Clears the current contents of the status window. 2. Save Button – Save the current contents of the status window to a specified file. 3. Skip Button – Skips all current status messages queued up by the application for display. Under some high message traffic conditions, the status window will queue up messages for display because it may not be able to keep up with influx of messages. This button will flush the current queue and indicate in the status window how many messages were skipped and show the tail end of the message queue. 4. Remaining– This is count of queued up status messages waiting to be displayed in the status window. The Skip button is most useful when this count is very large and can be useful to flush the messages and see the final status in the queue. 5. Status Options – Special options for controlling the status window: a. Keep History – [Checked] Append all status messages. [Unchecked] Clear status window upon each command operation.
14 b. Status Timestamps – [Checked] Show local timestamp on each status message. [Unchecked] No timestamp. c. Read Only – [Checked] Does not allow user to input any text in status window. [Unchecked] Allows the user to input notes in the status window, which can be useful when logging data and results. d. Large Window Buffer – Increases the size of the window buffer before flushing. 6. Packet Options – Special options for controlling Indy packet displaying a. Decoded Packets – Displays high level decoded packet information. b. Raw Packets 8 – Displays raw packet data in bytes. c. Raw Packets 32 – Displays raw packet data in 32-bit words. d. Packet Timestamps – Displays packet timestamps in milliseconds (when available in the packet). Status Timestamps Decoded Packets Raw Packets 8 Raw Packets 32 Packet Timestamps The status window will self flush automatically when the status window buffer is full. The window will indicate how many times it has self flush at the top of the status window. The current windows buffer if 2^16 characters which is approximately equivalent ot 1500 singulations of 96- bit EPCs. Use the large window buffer option to increase the windows buffer to 2^22. The Help Tab contains the decoded packet descriptions for reference. The following is the summary of the decoded packet formats:  Inv, NB Rssi (d), Rssi (d), PC (h), EPC (h), CRC (h), TID (h)  Access, Command (s), Tag Error (h), Proto Error (h), Write Count (d), Data[] (h)  Debug, Overflow (d), Underflow (d), Data Type (d), Timestamp (d), Id (d), Counter (d), Data[] (h)  XY-Pair, Id (d), Calculation Time Us (d), X (d), Y (d), Res0 (d), Res1 (d), Res2 (d), Res3 (d) Info Bar The Info Bar indicates when a reader is connected or when no reader is connected. The Info Bar will also indicate the type of connection either USB or UART. Enumerate The Enumerate Button will execute the reader enumeration process. The application will scan the USB interface and the selected COM port for valid readers. The enumeration is <2/18/2010 11:05:49 AM> Inv, 42, -78.0, 3000, 11112222CCCCDDDDEEEEFFFF, 7098 Inv, 42, -78.0, 3000, 11112222CCCCDDDDEEEEFFFF, 7098 Inv, 42, -78.0, 3000, 11112222CCCCDDDDEEEEFFFF, 7098 T:0005 V:01 F:02 L:0007 [ 45 6A 0A 00 58 6D 04 01 4A FE 00 00 30 00 AA AA BB BB CC CC DD DD EE EE FF FF 4A 5B ] Inv, 42, -78.0, 3000, 11112222CCCCDDDDEEEEFFFF, 7098 T:0005 V:01 F:02 L:0007 [ 000A6A45 01046D58 0000FE4A AAAA0030 CCCCBBBB EEEEDDDD 5B4AFFFF ] [682579] Inv, 42, -78.0, 3000, 11112222CCCCDDDDEEEEFFFF, 7098
15 only performed when the application is started and when the user presses this button. If a new reader is connected after the application is started, the enumeration process must be executed to control the reader. The reader list will be repopulated when the enumeration is complete. If the reader is not in the pull down list, check the cable connections to make sure the reader is connected correctly. Depending on the situation and nature of readers using the UART port, if the reader is not responding (in UART mode) it is best to shutdown the application and restart to re-enumerate the radio. When changing the COM port to enumerate, the application will need to be restarted (as indicated in the status window) to apply the settings. The RFIDcomm.cfg is used to configure the COM port to control, and by default (after installation) it is set to COM1. Connect The Connect Button will attempt to make a connection to the reader selected in the pull down menu. Upon a successful connection, a new set of menus will appear as shown in the following figure. If the reader is not connected successfully, it will be indicted in the status window and no menus will appear. After the reader is connected it is queried for its parameters. 1. Serial Number 2. Bootloader Version (if available and active) 3. Mac Firmware Version and CRC 4. RF Transceiver Info –R1000, R2000, R500 5. Host To MAC Interface = USB or COMx 6. Build Target – 1 = R1000, 2 = R2000, 3 = R500 7. Region – 0 = FCC, 1 = ETSI, 2 = JAPAN
16 The Info Bar will be updated with the name of the connected Reader and the activated Host To MAC interface. Disconnect and Reset The Disconnect Button will attempt to disconnect from the connected reader. The menus will disappear and the unconnected state will be indicated. The Reset Button will attempt to reset the connected reader and will also make the menus disappear. Cancel and Abort The Cancel and Abort Button will issue the respective command to Reader when executing a MAC Command. The status window will indicate the issuing of the command and the reader will respond accordingly. IndyTool Functions These sections describe the functions found in the visible menus when a reader is successfully connected. Register Access The Register Access menu is shown in the following figure.

MAC – Regular MAC Register a. [Read] The read address and count are the inputs. The count indicates how many consecutive addresses to be read. If the application reaches a register that is not readable, it will stop reading. b. [Write] The write address and data are the inputs. This is single write access. 2. MAC Bank – Banked MAC Register a. [Read] The read address and count are the inputs. The count indicates how many consecutive addresses to be read. If the application reaches a register that is not readable it will stop reading. A banked read will detect if the register is a banked register and display the entire banked contents. If it is not a banked register, the single value is displayed. b. [Write] The write address, data and bank number are the inputs. This is a single write access. If the address is not banked, an error will be displayed. 3. Bypass – MAC Bypass Register a. [Read] The read address and count are the inputs. The count indicates how many consecutive addresses to be read. If the application reaches a register that is not readable it will stop reading. b. [Write] The write address and data are the inputs. This is single write access. 4. OEM – OEM Register a. [Read] The read address and count are the inputs. The count indicates how many consecutive addresses to be read. If the application reaches a register that is not readable, it will stop reading. b. [Write] The write address and data are the inputs. This is single write access. 5. LinkProfile – Link Profile Transceiver Register a. [Read] The read address, count, and profile Id are the inputs. The count indicates how many consecutive addresses to be read. If the application reaches a register that is not readable, it will stop reading. b. [Write] The write address, profile Id, and data are the inputs. This is single write access. All the results are displayed in the status window.

19 Depending on the function selected, the appropriate inputs fields are displayed and valid values are required for all fields. Tag Access Scripts The Scripts menu is shown in the following figure. Batch Script The Batch Access allows a user to have preconfigured access scripts to quickly configure the reader for a specific operation. When the Run is pressed a dialog box prompts the user to select a batch file for execution. The batch files are basic ASCII text with specific commands to execute in order. There is a Syntax Help button to assist a user with the script format when operating IndyTool without the manual. The ReRun Button will re-run the last loaded script file without prompting. The Batch Script Syntax format legend is as follows: Tag Access [Read] Read = Bank:EPC Offset:0002 Count:0001 APwd:00000000 Command Begin (Cmd = 0010) EPC = 3000CFE900238C87234200000000 Read = Flags:80 TagErr:00 ProtErr:0000 Data:CFE9 Command End (Status = 0000) Access Count = 1 Tag Read Executed Tag Access [Write] Write = Bank:EPC Offset:0002 Value:1234 Count:0001 APwd:00000000 Command Begin (Cmd = 0011) EPC = 3000CFE900238C87234200000000 Write = Flags:00 TagErr:00 ProtErr:0000 WriteCount: 1 Command End (Status = 0000) Access Count = 1 Tag Write Executed Batch Script Help Legend * Decimal value or Hex Value (0x_) ** Same as *, but in addition -1 for all banks # is the comment character 'durationMs' - Indicates time in ms before sending cancel 'inventory' - Executes inventory command and dumps summary upon completion Commands script,sleep,*durationMs
20 The following are a list of commands that are supported: 1) Script Sleep 2) Mac Command and EngTest Commands (with duration option) 3) Read/Write of MAC, MAC Bank, Bypass, OEM, and Link Profile Registers The commands are straightforward and follow the same input requirements as the GUI, but are in comma separated format. The ability to put comments in the scripts is also available by using the # symbol. Decimals values are the default input, but if hexadecimal is preferred then add the prefix 0x to the input. Note that ‘single_entry’ is provided as an alias to the ‘oem,write’ command for backward compatibility with previous oem_tool formatted files. For example, to configure the reader for Fixed Q algorithm with a Q value of 0, the following commands can be placed in a batch script. mac,write,0x901,0 # Configure MAC 0x901 with 0 macbank,write,0x903,0,0 # Configure MAC 0x903 Bank 0 with 0 There is a checkbox option called “Batch Stop On Error” that will halt executing a batch script on any access or syntax error. This may be useful when the use case requires all the accesses to be successful (for example, when first writing the batch script and checking for typographical errors). If the checkbox is not checked, the batch will continue to execute even if an error is detected. Jscript The only function available in the JScript menu is to run a JScript. When the button is pressed, the user is prompted with a dialog for selecting a JScript for execution. If the script is valid, IndyTool will disconnect from the reader, run the Jscript, and then reconnect back to the reader for IndyTool control. mac,command,*id mac,command,*id,*durationMs mac,engtest,subcmd,arg0,arg1 mac,engtest,subcmd,arg0,arg1,*durationMs mac,inventory mac,inventory,*durationMs mac,read,*address mac,read,*address,*count mac,write,*address,*data macbank,read,*address,**bank macbank,read,*address,**bank,*count macbank,write,*address,*bank,*data bypass,read,*address bypass,read,*address,*count bypass,write,*address,*data oem,read,*address oem,read,*address,*count oem,write,*address,*data single_entry,*address,*data linkprofile,read,*address,*id linkprofile,read,*address,*id,*count linkprofile,write,*address,*id,*data
21 The JScript feature is legacy feature from the original MACTool which IndyTool is replacing. The low level MacComDirect Library is used to execute these JScripts. IndyTool provides a GUI interface to run these scripts. However, when IndyTool is installed, the MacComDirect is registered in the system so that a JScript can be run outside the IndyTool application. An example JScript is included in the installation directory as a sample. The example script is called Example.js. The example will query and display the current MAC Error in a pop up box.

23 Inventory The Inventory menu is shown in the following figure. The Inventory menu has five inventory functions: 1. As configured – Executes the Inventory command without modifying any Mac Registers 2. Single Cycle - Executes the Inventory with HST_CYCLES set to 1. 3. Infinite Cycles - Executes the Inventory with HST_CYCLES set to 0xFFFF. 4. Test Channel – Executes the Inventory with currently Set Test Frequency. If no test frequency is set an error will occur. The HST_CYCLES will also be set to 0xFFFF. 5. Test Channel with Continuous Tx - Executes the Inventory with currently Set Test Frequency. If no test frequency is set an error will occur. The HST_CYCLES will also be set to 0xFFFF. The continuous_tx bit in HST_TEST_INVENTORY_CFG will also be set. The Start and Stop can be used to initiate and terminate the selected inventory option. Stop is the equivalent to the Cancel Command. The note indicates that the Inventory must be preconfigured prior to executing the command (other than the registers that will be explicitly set by IndyTool as described). It is assumed that the user has preconfigured all the parameters using the Register Access menu. After the Inventory command is complete, the basic singulation rate, tag count, duration and unique count are displayed to the user. The Logical Antena 0 control box allows the configuration of the ohysical antenna port and Inventory Command Begin (Cmd = 000F) EPC = 3000CFE900238C87234200000000 EPC = 3000CFE900238C87234200000000 … EPC = 3000CFE900238C87234200000000 EPC = 3000CFE900238C87234200000000 Command End (Status = 0000) Singulation Rate =34.95 tags/second (70 tags in 2.00 sec, 1 Unique) Inventory Success

32 Chapter 3 Introduction The Tracer application is a .NET-based graphical user interface (GUI) tool that uses the Indy RFID Host Library API to exercise the functionality of the reader platform, a platform that is based on the Indy R1000 and R2000 chip, and Indy R1000 and R2000 firmware respectively. Tracer is dynamically linked to the Indy RFID Host Library. Therefore, there is no need to install the interface library separately. However, the USB / UART host driver must be installed prior to using Tracer. Tracer is supported on Windows XP only. The goal of this document is to explain the operation of the tool. This document does not explain the underlying RFID functionality that it is controlling via the Indy RFID Host Library API. Tracer Installation Installation Requirements Tracer requires Microsoft Windows XP Professional with Service Pack 1 (or later). Tracer also relies on release 2.0 of the Microsoft .Net Framework. The Tracer setup program checks to ensure that the correct version of the .Net Framework is installed. If the correct version is not installed, the Tracer setup program offers to install it. The user may also download and install a copy of the .Net Framework from the Microsoft Windows Update Site (http://update.microsoft.com/) or the Microsoft Download Center (http://www.microsoft.com/downloads/). To communicate with the reader, the current version of the USB / UART host driver must be installed. See the Indy SDK Getting Started Guide for additional information. To take advantage of the data import/export feature, Microsoft Excel 2003 is required. Installation It is possible for multiple versions of Tracer to co-exist on a single system, so long as a unique install path is used for each, such as the default installation directory. Installation Procedure To install the Tracer tool: 1. Double click the Tracer installer file, Tracer v2.4. 2. 2.msi, to launch the installation wizard. 3. When prompted, designate the desired installation directory. The default is [Program Indy Tracer for Demonstration
33 Files]\IMPINJ\Tracer v2.4.2\. 3. Installation includes the C++ runtime libraries and adds a desktop shortcut to the Tracer application. 4. To Start the Tracer application:  Double click the desktop shortcut, or Use the Start Menu. For example, if installed to the default directory:  Click Start, Select All Programs, IMPINJ, Impinj Tracer v2.4.2, Click Tracer.  Open the Tracer installation folder and double click Tracer.exe. Removal Procedure To uninstall the Tracer tool: 1. Click Start, Select All Programs, IMPINJ, Impinj Tracer v2.4.2, Click Uninstall Tracer. 2. When prompted to uninstall this product, click Yes. Alternatively: 1. Open the Control Panel and select Add or Remove Programs. 2. Select the entry for the Tracer version to uninstall and click Change/Remove. 3. When prompted to remove this product, click Yes. Configuring for UART Operation In the installation directory there is a file called RFIDcomm.cfg. This file contains the COM Port number if UART operation is desired. The Tracer program will need to be restarted if this files is changed. With UART operation, only a single reader can be controlled. Tracer Usage This section describes the features of the Tracer Application. Tracer has been adapted with reader platform differences in mind. Consequently, Tracer version 2.2.0 supports both the Indy R1000-based and R2000-based reader, hereafter referred to as the reader. Tracer Appearance The Tracer consists of a main display window and a floating control panel window. See figure below.  The main window contains a menu and a main display area used to show different views of the data received from the reader.  The floating control panel is used to start, stop, and pause inventory rounds, and to perform other reader actions. Tracer User Interface Main Window (left) and Control Panel (right)
34 Selecting a Device and a Mode Selecting a Device When the Tracer application starts, it attempts to open all attached readers. Each attached reader is listed separately in the Device menu. If no readers are found, the application displays a warning and the Device menu is empty. The reader that is found first is automatically selected as the active device. The name of the active reader device is always displayed on the window caption. To change the active reader, make a selection from the Device menu as shown in the figure below. Controlling a Device The Device Menu After making a selection from the Device menu, you can control the active reader from the Reader Control menu or from the floating Control Panel. The figure below shows the Control Panel buttons and describes the actions they perform. Reader Control Panel

RFID Data Views Overview The Tracer provides several views that allow users to examine RFID data from different perspectives. Use the View menu (on the main window) to select different views. Tracer provides two types of data views:  Live data views, which are captured in real-time from the reader  Post-capture views, which are generated after an operation is completed The live data views display data as the packets arrive from the reader. The application applies minimal processing to this live data. The following table describes the three live data views that are available. Live Data Views View Name Contents Summary View Overview statistics about the current session, currently executing command and reporting time slice. Standard View A list of unique tag singulations (tag id inventoried) in the session and a count of the number of times the id was read (inventoried). Protocol Trace A graphical view of the packet data for the current (active) command broken out by the packet fields. Note that while a reader is actively executing a command, such as Inventory, only live data views are available. Even if a user has selected a post-capture view, the view is automatically switched to a live data view when a command is issued to the reader. While the command is running, users can switch between any of the three live views (Summary, Standard and Protocol Trace). However, the user interface prevents users from switching to any of the post-capture views. See the figure below. View Menu Options – During Reader Command Execution Performing Post-Capture Processing After one or more reader functions has completed, Tracer must perform the post-capture processing to create the post-capture views. The post-capture processing builds an index of the captured data which provides the data for the post-capture views. You can perform the post processing by initiating it yourself or by configuring the application to invoke it automatically. The procedure for each approach is described below:  To initiate the post processing (i.e., to build the indexed data file), select Build Post-Capture Views as shown in the figure below. This option is enabled after the reader functions have completed.
42 View Menu Options - Build Post-Capture Views  To configure the application to automatically invoke the post-capture processing: 1. From the Tools menu, select Tracer Options. The Tracer Option dialog box displays. 2. Select Automatically perform post-capture processing as shown in the figure below. Automatically Perform Post-Capture Processing When the post-capture processing completes, all views become available from the View menu, as shown in the figure below. View Menu Options - Post-capture Views Except for the Reader Protocol view, all post-capture views are divided into three groups under the submenus:  Packet Views  Diagnostic Views  Performance Views The Protocol Trace is the only view that supports the display of both live and post-capture data. When the reader is active, the Reader Protocol view displays the last one thousand captured packets for the current command. When the post-capture process completes, the Reader Protocol view displays all packets for the active session.
43 The following table lists the post-capture packet views that are available: Post-Capture Packet Views View Name Contents Tag Access Lists in chronological order all Inventory Response packets received from the reader. The view includes the Tag ID, time of packet arrival, the Antenna number, device time, the access type, and the tag data. Command Summary Provides summary information about the commands executed by the reader in the current session. Data items include elapsed time of the command, execution mode, tag count, unique tag count, and tag read rate. Antenna Cycle Summary Provides summary information about the antenna cycles executed by the reader in the current session. Data items include the number of antennas included, the tag count, unique tags, and tag singulation rate. Inventory Cycle Summary Provides a summary of all of the inventory cycles included in the current session (or since the last time the session was cleared). The view includes the total and unique tag count, logical antenna number, and read rate. Inventory Round Summary Lists data related to each inventory round including the antenna used, tag count, and elapsed time in milliseconds. Inventory Parameters Lists the parameter used in the session’s inventory rounds. The following table lists the post-capture diagnostic views that are available: Post-Capture Diagnostic Views View Name Contents All Packets (Raw Format) Lists in chronological order all packets received from the reader. Invalid Packets Lists invalid or unrecognized packets, the raw data, and the parsing error. Inventory Cycle Diagnostics Lists diagnostic information for each inventory cycle. Note: The extended data format must be selected to obtain this information. Inventory Round Diagnostic Lists the diagnostic information for each inventory round. Note: The extended data format must be selected to obtain this information. The following table lists the post-capture performance view that is available: Post-Capture Performance View View Name Contents Singulation Rate Data Provides data useful for calculating the read rate achieved by the reader. Exporting Data The Tracer application allows you to export data to Microsoft Excel 2003. To export data:  From the File menu, click Export. A dialog box opens from which you can select the views you wish to export. You can export one or more views at a time. The application saves exported files in the user’s temporary directory. After the export completes, Tracer invokes Microsoft Excel, or the associated application for xml format worksheets, to open the exported data file. Each view selected for export becomes a separate sheet in an Excel workbook. Note: Microsoft Excel allows only the first 65536 rows in each view to be exported. If a session is too big for Excel, you can always view it in the Tracer application.
44 Logging Data Tracer supports the logging to a text file of all packets received from readers. See figure below To enable logging: 1. From the Tools menu, click Tracer Options. This opens the Tracer Options dialog box. 2. In the Tracer Options dialog box, click the Data Logging tab. 3. Select the Enable Logging check box. 4. If desired, specify an alternative directory in which log files should be stored. Data Logging The log files created by Tracer are named rfidxxxx.log, where xxxx is a four digit sequence number. The figure below shows an example of log file content. Log File Example
45 The log file contains four fields separated by tab characters. These fields are defined in the following table. Log File Field Definitions Field Contents Radio Index A unique serial number for the reader. Time stamp Elapsed time in milliseconds from the start of the session. Symbolic Name The symbolic name for the packet. Packet Data The packet data in hexadecimal format. Accessing and Changing Reader Configuration The Tracer application allows the user to configure many of the settings of the attached readers. To access the configuration panel:  From the Reader Control menu, select Configure Reader. Alternatively, from the Control Panel, select Configure Reader. See the figure below. This opens the Tracer Reader Configuration dialog box.
