Speedway Reader IPJ-R1000 for Gen 2 UHF RFID 4 Mounting the Speedway Reader When securing the unit with #10 screws via the four mounting brackets, the Speedway reader may be mounted horizontally or vertically on a stable surface where it will be safe from disturbance. Keep the unit away from direct sunlight, high humidity, extreme temperatures, vibration, and sources of electromagnetic interference, as any combination of these conditions may degrade performance or shorten the life of the unit. Connecting the Antenna(s) Do not apply power prior to making the required antenna connections, and always power down the reader before removing an antenna port connection. The Speedway reader is equipped with four (4) independent, bidirectional, full duplex TX/RX ports, which must be cabled to their respective, Impinj-approved antennas prior to power-up. Unused antenna ports must be left unconnected; they should not be terminated. Note: Reader power has been factory preset to 30 dBm to accommodate an antenna with 6 dBi composite gain (inclusive of cabling). The Speedway reader may only be operated with Impinj-approved antennas and can radiate no more than 36 dBm EIRP per FCC Part 15.247 regulations. To obtain the maximum allowable reader power setting, the following expression should be used: Speedway power setting (in dBm) = 36 – Antenna Gain (in dBi) where the antenna gain includes the loss of the associated cable from the reader to the antenna. Approved antenna vendors, model numbers, gain characteristics, and associated RF cable/connector include: • Cushcraft Model Number S9028PCL/R (left- or right-hand CP); 6 dBi gain, with integrated pigtail to RP-TNC female connector Connecting Power Connect the power plug into the reader’s DC power input and secure the threaded locking jack. When the DC connection is secure, connect the AC power plug into a suitable 100-240 VAC, 50-60 Hz power outlet. The reader will begin its boot sequence. Note: normal boot time for the reader’s operating system is ~20 seconds. The reader cannot be commanded until the boot sequence is complete. Connecting & Configuring the Network Interface Reader control is accomplished via either TCP/IP (Ethernet) or serial (RS-232) interfaces on the Speedway unit. Preparing the IP Interface Before power-up, connect the reader to your network via the Ethernet port. If your network is capable of communicating to the reader in its default IP configuration, then no serial interface is required. Connect the PC’s Ethernet port to the Speedway reader using one of the following two methods: • Use of a single Ethernet crossover cable with PC IP address set to a static value (e.g., 192.168.1.10) within the subnet of the reader. • Use of an Ethernet router or switch with either PC IP address set to a static address within the subnet of the reader (switch) or router’s DHCP set to provide the PC with an IP address within the reader’s subnet. To verify correct TCP/IP connectivity ping (using the "ping" command) or traceroute (using the “traceroute” command in a Linux environment, or the “tracert” command in a Windows environment) the reader’s IP address using the PC’s command line interface. Open the PC’s web browser application and connect to the reader's hosted webpage (e.g., http://192.168.1.10). To get to the reader's command line interface, use SSH Client or Telnet Client software. !
Speedway Reader IPJ-R1000 for Gen 2 UHF RFID 5 Default login (case-sensitive) is as follows: User Name: root Password: impinj Preparing the Serial Interface Serial communication with the reader can be used at any time in conjunction with, or in lieu of, Ethernet connectivity in order to configure the reader. The serial interface may be necessary to establish initial communications with the Speedway reader if your network equipment is not compatible with the default network configuration of the reader. In this case, the reader’s network connection can be configured using the serial port; Ethernet connectivity can then be used for control thereafter, if desired. To begin, launch HyperTerminal on a PC via the serial port (or a similar communication program, such as minicom in Linux) to establish serial reader communication. Configuration settings are entered via the command line interface, the prompt for which appears when the reader is connected to the PC via the serial interface port. Set the communication parameters of the terminal software as follows: • Data rate: 115200 bps • Data bits: 8 • Parity: None • Stop bits: 1 • Flow control: None Configuring the Network via the Command Line Interface Whether using HyperTerminal (Serial Interface), SSH (IP Interface), or Telnet (IP Interface), log in with the same user name and password indicated earlier. The syntax for setting the reader's host name is as follows: platformname <host name> Configuring the Speedway reader for use within existing network environments is done via the netconf utility, which resides on the reader. The three configuration modes, accessed via the netconf utility, include: 1. Static configuration mode 2. Dynamic configuration mode without a record 3. Dynamic configuration mode with a record Static Configuration Mode To set a static IP configuration, use: netconf <IP address> [optional parameters] The first parameter to the utility must be the actual IP address for the reader to be used on the network, expressed in dotted-quad notation (e.g., 192.168.20.100). The parameters shown in Table 1 are optional qualifiers for the remaining networking settings. If they are not provided, the Speedway reader will assume defaults for their values.
Speedway Reader IPJ-R1000 for Gen 2 UHF RFID 6 Table 1 Optional Parameters Optional Parameter Definition Action -b Broadcast Address Defaults to IP address masked with 255 -g Gateway Address Defaults to IP address masked with 1 -m Netmask Address Defaults to a class C network -n Network Address Defaults to IP address masked with 0 Operationally, Speedway reads the settings provided to the netconf utility via the syntax shown above, computes the remaining settings that were not entered, and uses this information to reconfigure its networking interface. Note that no steps are taken to verify the correctness of these settings with any of the network configuration servers; the user must ensure the validity of the data entered at the command line. Furthermore, in the static configuration mode, the reader will not contact any of the network management services (such as DHCP or DNS) to register its presence. When connecting in this mode, unless steps are taken by the network administrator at the deployment site, the reader can only be contacted via its IP address, and not its host name. Dynamic Configuration Mode without a Record The dynamic configuration mode relies on a DHCP server to request the necessary network settings, which can be assigned dynamically when the reader is rebooted or reconfigured with netconf. In addition to providing more flexibility than the static mode, the settings provided by the network management authority (the DHCP server) will be assured to be accurate and free of contention. To invoke dynamic configuration from the netconf utility, simply run the following command: netconf dynamic In executing the command, the reader issues a DHCP query to request all the necessary network settings. As shown in Table 2, the DHCP query includes a number of fields that identify the reader as a unique device on the network, such that the DHCP server can manage the configurations on a per-device or per-device-type basis, as appropriate. Table 2 DHCP Query Fields Field Description Vendor Class Identifier Set to “RFID” to identify the reader as an RFID device DHCP Client Identifier Set to the MAC address of the interface to identify the reader as a unique network device Vendor Encapsulated Options Set to “Cisco Systems” User Class Set to “Default” Host Name Set to the current local host name of the reader The DHCP server responds with all the necessary information that the reader will require to configure its network interface, the most important of which includes: 1. The new IP address, netmask, gateway address, and any other address information required for routing IP traffic through the network. !
Speedway Reader IPJ-R1000 for Gen 2 UHF RFID 7 2. The active domain name servers on the network, as well as the DHCP lease status. 3. Optionally, the new host name and the domain name. If the host name is specified, then the reader will set its local host name to this value, overriding the value set previously. Dynamic Configuration Mode with a Record This network configuration mode, which also relies on the DHCP server for its network settings, is an extension of the dynamic configuration without a record mode. It is useful in those cases where the network administrator prefers to create preconfigured records for some or all of the reader devices on the DHCP server. In this mode, rather than the server computing default query field values, it returns the preconfigured data in response to the DHCP request. Note that in this mode, the reader’s host name may be overridden with the response returned by the DHCP server. Configuring Speedway via the Web Interface If connecting via host name, navigate the browser to http://speedwayn, where n represents the host name suffix (simply concatenate the unit's serial number to the word "speedway" to complete the host name entry). You'll then be directed to the specific Speedway unit's homepage (see Figure 2), which details the host name, IP address, and system statistics information. Figure 2 Speedway Reader Homepage To proceed to the configuration menu, click on the Config tab in the screen's navigation bar (will require the same username/password as indicated earlier). The Upload Configuration to Reader screen will appear, which provides the option of loading preset configuration settings to the reader. These files are created by establishing the configuration settings on a "golden" reader unit, and then downloading them to a locally stored configuration file. Note, of course, that when this file is uploaded to other readers, fields such as host name must be updated.
Speedway Reader IPJ-R1000 for Gen 2 UHF RFID 8 Figure 3 Config Default Page (Upload/Download Configuration) The three other submenu options in Config are Host name, Network, and Access. Access Configuration (see Figure 4) provides for changing the password associated with the root command line login. Figure 4 Access Configuration The host name can be changed under Host Name Configuration (Figure 5).
Speedway Reader IPJ-R1000 for Gen 2 UHF RFID 9 Figure 5 Host Name Configuration The network configuration can be established or modified via the Network tab (see Figure 6). If you choose Dynamic, there's nothing left to do; the host name will be assigned using DHCP over the network. If Static, the fixed IP address and its associated parameters are entered in the corresponding fields. These fields have no meaning in the Dynamic setting. Figure 6 Network Configuration
Speedway Reader IPJ-R1000 for Gen 2 UHF RFID 10 Speedway Reader Settings The Speedway reader applet is a Java program that runs from within a web browser (see Figure 2, Speedway Homepage). Speedway requires Java Runtime Environment (JRE), version 1.4.2 or later. Note that Windows 2000 default is 1.3.1. The latest version of JRE can be downloaded from: http://java.com/en/download/manual.jsp The reader applet is accessed via the RFID menu tab at the top of this page. Clicking this tab will bring up a dialog box prompting the user to enter a login ID and password, the default for which is: User name: root Password: impinj The Java program will load and open the Settings page (see Figure 6) The five user-selected fields on the Settings page include Profile, Antenna, Session, Transmit Power, and Channel, each of which are described below. Figure 6 Speedway Reader Settings Page Profile The reader mode is established via the Profile pull-down menu, the parameters of which are detailed in Table 2. Each profile (0−3) is a factory preset that configures the reader according to the profiles' respective default settings (Figure 6 shows the settings for Profile 0).

Speedway Reader IPJ-R1000 for Gen 2 UHF RFID 11 Antenna The Speedway reader supports four (4) independent, bidirectional, full duplex TX/RX ports, which must be cabled to their respective, Impinj-approved antennas prior to power-up. Each antenna port is labeled (ANT1−ANT4) on the Speedway unit, and these designations correspond to the Antenna selection buttons that appear on the lower half of the screen. Only those antennas activated by clicking the appropriate button(s) will be operational. Session The reader may be assigned to one of four Sessions (0−3), selectable via this pull-down menu. A function of dense-reader mode, the use of sessions allows as many as four different readers to access the same population of tags through a time-interleaved process. In this mode, a shelf-mounted reader in the midst of a counting operation (assigned to, say, session 1), for example, may be interrupted by another reader entering the field—possibly a handheld reader—to perform its own inventory operation (in session 2, perhaps). Dock door and forklift readers, assigned to sessions 3 and 4 respectively, might also initiate an inventory round. Because Gen 2 tags maintain a separate "inventoried" flag to keep track of each of these various random and independent sessions, they're able to seamlessly resume their participation. Transmit Power The reader power setting is selected from the Tx Power pull-down menu. Ranging from 15 dBm to a maximum of 30 dBm (in .25 dB increments), measured at the Speedway reader's antenna ports, the maximum setting assumes an antenna with 6 dBi composite gain (inclusive of cabling). An Impinj-approved antenna with higher gain may be used provided the Speedway reader power is reduced so as not to exceed 36 dBm total transmitted power, the maximum allowed by the FCC (see Connecting the Antennas). Channel The FCC stipulates frequency hopping across the North American spectrum allocated to UHF RFID (902−928 MHz, with hopping occurring between 902.75−927.25 MHz in 500 KHz steps). As such, the Speedway reader does not allow the setting of a static frequency. For North American operation, Channel is factory-set and fixed to frequency hop. Using Filters The Inventory Filter screen (see Figure 7) is the user interface to the Select command, which the reader may apply successively to sort a particular tag population based on user-defined criteria, which may include union, intersection, and negation-based tag partitioning (union and intersection operations are performed by issuing successive Select commands). Select commands apply to a single memory bank; the MemBank field specifies if the criteria applies to the TID, EPC, or user memory, as follows: MemBank 00 (0): Reserved MemBank 01 (1): EPC MemBank 10 (2): TID MemBank 11 (3): User Successive Selects may apply to different memory banks. The Bit Offset and Bit Length fields are used to target a specific portion of the tag memory on which to perform the filtering, while the Pattern field contains the comparison bits of interest. As tags are read, the pattern is evaluated against the Select criteria, which includes Equal, Not Equal, Greater Than, or Less Than options in the Comparison field. The Inventory Filter allows the use of two sets of criteria (defined by primary filter A and secondary filter B) that may be used separately, jointly, or not at all (the pull-down options include No Filter, A ONLY, A AND B, A OR B). When applied to an inventory round, only those tags that match the Select criteria will be displayed.
Speedway Reader IPJ-R1000 for Gen 2 UHF RFID 12 A Figure 7 Inventory Filter Accessing Tags After acknowledging a tag, the Speedway reader may choose to access it. The Access command set comprises Req_RN, Read, Write, Kill, Lock, Access, BlockWrite, and BlockErase. Tag Access (see Figure 8) adds a Mask field to the filtering operation, which allows the user to mask individual "don't care" bits or segments of the matching pattern, where "1" identifies a bit of interest and "0" represents a masked bit. Tag Access differs from the Inventory Filter operations in several respects. First, rather than simply continuously inventorying a population of tags, Tag Access allows the user to automatically Halt the inventory process upon finding a tag of interest (e.g., a tag that meets the Halt Filter criteria). At this point, the tag can be automatically read, written, locked, killed, or erased according to the action selected in the Action pull-down menu. Furthermore, the action is applied only to the selected MemBank, and within it, the desired memory rows (00−07), the rows being made up of 16-bit words. If Action calls for a write, the specific bit pattern to be written must be entered (in hex format) in the corresponding field(s) below the selected row number(s). Note that multiple selected rows must be contiguous. The Tag Access view is consistent with the Operation view (described below) in that settings applied to one are valid for the other.
Speedway Reader IPJ-R1000 for Gen 2 UHF RFID 13 A Figure 8 Tag Access Operation If the Halt Filter has been activated in Tag Access, this status will be indicated in the Operation view with the text **Halt Filter** appearing at the top of the screen. Likewise, if the Inventory Filter has been activated, the text **Inventory Filter** will also appear. The inventory operation is enabled via the Start/Stop toggle button. Auto Continue Referring to the set of three buttons in the lower-left portion of the screen, Auto Continue directs the reader to continue singulation after a halt condition has been met. Otherwise, if the Halt Filter has been set, the reader will stop reading and return control to the user, resuming operation only when the Continue button has been clicked by the user. Note also that Halt does not require any subsequent action. Act Once The Act Once button, if enabled, directs the reader to execute the action indicated in the Tag Access Action setting (read, write, lock, kill, etc.). If the operation is successful (see Last Status column in the primary read window), the reader will continue inventorying or halt operation, depending on the status of the Auto Continue setting. Note that if the Act Once setting is not enabled, and the action indicated is a write, the reader will continuously write the tag over and over in a continuous loop. If, on the other hand, both Act Once and Auto Continue are enabled, the reader will write the tag once, and then continue the inventory operation, responding in accordance with the Inventory Filter settings that have been established. Read TID As tags are read, their EPC numbers appear in the primary window of the Operation screen. If the Read TID button has also been enabled, the logo of the tag silicon manufacturer corresponding to the TID will also be displayed. Monitoring Inventory Results The Start/Stop button controls singulation of tags within range of the reader. In addition to the EPC and TID (if enabled), the results displayed include Read Rate (expressed as tags/sec) and Running Time (in hh:mm:ss from last Start). Total Tags and Total Active Tags report statistics on the total number of tags read as well as the number of tags currently in the reader's field of view. Active tags being read are displayed in white fields, and fade to blue after not being seen by the reader within the last ~10 seconds. To see all tags and their status, simply scroll the screen. Finally, the Clear button clears the results of the inventory operation that commenced with Start.
Speedway Reader IPJ-R1000 for Gen 2 UHF RFID 14 To change settings from Operation mode: a. Stop continuous singulation using the Start/Stop button b. Return to Home screen and configure reader to desired new mode c. Return to Operation mode and re-start continuous singulation Figure 9 Operation Versions The Version screen (see Figure 10) simply reports the versions of the four primary components of the Speedway reader.

Technical support is available via phone (206-517-5300) or e-mail (info@impinj.com). Table 3 Troubleshooting Problem Solution The reader’s default page does not load Most likely the reader operating system is still booting or TCP/IP connectivity has been lost. Retry or “ping” the reader to verify connectivity. If more than 20 seconds have elapsed since power was applied, disconnect and reconnect power, then re-attempt to ping the unit after 30 seconds. Java applet does not load after selecting “RFID” from default page Verify that the PC’s web browser has Java Runtime Environment (JRE) of version 1.4.2 or later. The latest version of JRE may be installed from: http://java.com/en/download/manual.jsp “Initializing” or “Calibrating” dialog boxes do not disappear The reader has likely locked up. Power cycle the reader. Tags/sec rate varies when configuration settings are changed This is normal. Currently, the Maximum Throughput mode should have >200 tags/sec, while Dense-Reader or Initialization modes are ~100 tags/sec. Some transmit frequencies will be better than others (no interference or less noise). Best rates will be achieved with 10 to 30 tags within range. None of the recommend actions fixes the problem Power cycle the reader.
