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.
2.4. Connecting Power
Connect the AC power plug into a suitable 100-240 VAC, 50-60 Hz power outlet. The reader’s green Power LED will light
when power is on. The reader will then begin its boot sequence (the normal boot time for the reader’s operating system is ~50
seconds). The reader will not accept commands until the boot sequence is complete.
2.5. Connecting the Antenna(s)
The Speedway reader is equipped with four (4) independent, bidirectional, full duplex TX/RX ports (monostatic).
Caution Unused antenna ports must be left unconnected; they should not be terminated.
2.5.1. FCC and Industry Canada
!
Warning Position reader antennas such that any personnel in the area for prolonged periods of time may safely
remain at least 25 cm from the antenna’s surface. See FCC OET Bulletin 65, “Evaluating Compliance with FCC
Guidelines for Human Exposure to Radiofrequency Electromagnetic Fields,” and FCC OET Bulletin 56, “Questions
and Answers about Biological Effects and Potential Hazards of Radiofrequency Electromagnetic Fields,” for more
details.
!
Warning Readers of hardware revision 2.0 (see section 2.5.1.1) and higher and ru n ni n g software versions 2.6.0 and higher are capable of up to 32.5 dBm conducted power on the Speedway housing RF connector
and require professional installation.
For readers of revision 1.X.X, 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 (Equivalent Isotropically Radiated Power) per FCC Part 15.247 regulations. The Speedway output power
may be increased to provide the maximum allowable EIRP subject to a maximum conducted power allowance as well. The
maximum conducted power at the antenna connector can be no more than 30 dBm. The maximum allowable output power of
the reader can be set to satisfy both the conducted and radiated maximum criteria. The expression for the maximum re ader
power setting is:
where the composite antenna gain comprises the maximum linear antenna gain in dBi minus any cable loss between the reader
and antenna in dB. Approved antenna vendors, model numbers, and associated gain are listed below:
•Cushcraft Model Number S9028PCL/R (left- or right-hand CP); 6 dBi composite gain (including integrated pigtail
with RP-TNC female connector)
•Sensormatic Electronics Corp. model number IDANT20TNA25 (includes 25 foot Belden 7806A RG-58 coaxial cable

2.5.2. European Economic Area
European regulations allow a maximum radiated power of 33 dBm ERP (Effective Radiated Power) for high power RFID
systems. The maximum Speedway output power is determined by the following equation:
Maximum power setting (in dBm) = 33 – Antenna Gain (in dBd) + Cable loss (in dB)
For example, for an application with an antenna gain of 6 dBd and cable loss of 2 dB, the reader output power can be set no
higher than 33-6+2 = 29 dBm. Note that it is important to apply the antenna gain expressed in dBd (dB with respect to a
dipole), which is equivalent to the isotropic antenna gain (in dBi) minus 2.15 dB. Additionally, the antenna gain used to set the
output power must be the maximum linear gain of the applicable antenna.

3. Communicating with the Speedway Reader
Reader connectivity and control is accomplished via either network (Ethernet, TCP/IP) or serial (RS-232) interfaces on the
Speedway unit (see Figure 3-1).
If connecting via Ethernet, see Section 3.2. If your network equipment is not compatible with the default network configuration
of the reader (DHCP), connecting via the serial interface will be necessary to establish initial command line-level
communications with the Speedway reader. If making a direct serial connection, see Section 3.1.

3.1. Preparing Serial Connectivity
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
(via the command line interface) if your network equipment is not compatible with the default network configuration of the
reader (DHCP). In this case, the reader’s network connection can be configured using the serial port; Ethernet connectivity can
then be used for control thereafter.
Launch HyperTerminal (supplied with Microsoft Windows) or a similar communication program (such as Tera Term for
Windows or Minicom for Linux) to establish serial reader communication. Configuration settings are entered via the command
line interface (see section 4), accessed via your preferred terminal emulator, the prompt for which appears when the reader is
connected to the PC via the serial port and booted.
After connecting the Speedway reader’s serial port to the host PC’s valid/active COM port, plug the reader’s AC power unit
into a suitable 100-240 VAC, 50-60 Hz power outlet. The Power LED will illuminate when power is applied. The reader will
then begin its boot sequence. (Normal boot time for the reader’s operating system is ~50 seconds. The reader will not accept
commands until the boot sequence is complete.)
Set the communication parameters of the terminal software per Figure 3-2 (Tera Term screenshot shown).
Once the terminal window opens, log onto the reader by entering the established user name and password. The default login
(case-sensitive) is:
User Name: root
Password: impinj
The Speedway reader is now ready to accept command line instructions (see section 4).
Figure 3-2 Serial Port Configuration
13
Speedway Reader IPJ-R1000 for UHF Gen 2 RFID
3.2. Preparing Ethernet (TCP/IP) Connectivity
Connect the reader to your network via the Ethernet port (see Figure 3-3). If your network is capable of communicating to the
reader in its default IP configuration (DHCP), then complete and verify connectivity as described below. Note that the host
computer must be on the same subnet as the reader.
Ethernet
PC
Ethernet
Figure 3-3 Ethernet Connectivity
Connect the computer’s Ethernet port to the Speedway reader using one of the following two methods:
•Use 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.
•Use a single Ethernet crossover cable to connect directly to your PC with the PC IP address set to a static value within
the subnet of the reader.
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. Once connectivity is established, open the computer’s web browser application and connect to the Speedway
reader’s hosted webpage (see Section 4), and login to complete the Speedway reader configuration. The default login (casesensitive) is:
User Name: root
Password: impinj
Proceed to section 4 to configure the network.
3.3. Mach1 Interface
The Speedway reader has a comprehensive RFID Command Interface, the Mach1, used by the reader to communicate with
EPCglobal™ Generation 2 (Gen 2) RFID tags. Many application providers offer software that is compatible with Mach1.
Consult your solutions provider or applications software vendor for additional information.
14
Speedway Reader IPJ-R1000 for UHF Gen 2 RFID
4. Network Configuration
The network may be configured for the Speedway reader using the Rshell command line interface (CLI), accessed via the serial
port (see section 3.1) if your system does not support DHCP.
To complete the host name, concatenate the last three bytes of the unit’s MAC address (printed on the Speedway reader
enclosure and expressed in hexadecimal, e.g., MAC 00:16:25:00:41:0C) to the word “speedway” separated by “-” (e.g.,
speedway-00-41-0C).
Shown here are the essential configuration commands; for complete information on this interface, see section 8).
To view the reader's current configuration settings, enter the following command at the prompt:
> show network summary
The reader will respond with the following (sample only; actual data will differ):
At this point, the TCP/IP configuration parameters, such as its IP status (static or dynamic) and hostname, may be changed via
the following command examples:
•To set hostname, at the prompt, enter the command:
config network hostname <HOSTNAME>
• To set static IP address, at the prompt, enter the command:
config network ip static <IP ADDRESS> <NETMASK> <GATEWAY> <BROADCAST>
•Alternatively, either of the following two versions of the config network ip static command may be used, in which
case the reader will use default values for the unspecified parameters:
config network ip static <IP ADDRESS>
config network ip static <IP ADDRESS> <GATEWAY>
• To set DHCP, at the prompt, enter the command:
config network ip dynamic
You may now continue to use the Speedway reader in serial mode or connect to the network via the Speedway reader's
Ethernet port.

Speedway Reader IPJ-R1000 for UHF Gen 2 RFID
5. Speedway Reader Settings
Navigate to the Speedway reader's hosted webpage. If using DHCP with DNS hostname registration enabled, connect via the
default host name by navigating the browser to http://speedway-nn-nn-nn, where nn-nn-nn represents the host name suffix.
To complete the host name entry, concatenate the last three bytes of the unit’s MAC address (printed on the Speedway reader
enclosure and expressed in hexadecimal, e.g., MAC 00:16:25:00:41:0C) to the word “speedway” separated by “-” (e.g.,
speedway-00-41-0C).
If your DHCP server does not support DNS hostname registration, the option has been turned off in Rshell, or you are using a
static IP address, navigate to the IP address assigned (e.g., http://xxx.xxx.xxx.xxx
DNS server (e.g., http://hostname). You’ll then be directed to the specific Speedway unit’s homepage (see Figure 5-1), which
details the hostname, IP address, serial number, hardware revision, and system statistics information. Note that the actual GUI
appearance may vary from that shown in this User’s Guide.

Antenna
The Speedway reader supports four (4) independent, bidirectional, full duplex TX/RX ports. 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 third of the screen. Only those antennas activated by clicking the appropriate button(s) will be operational. (See Figure

Figure 5-4 Closeup of Variable Selections
Session
The reader may be assigned to one of three sessions (1−3), selectable via the Sessions pull-down menu. A function of densereader mode, the use of sessions allows as many as three different readers to access the same population of tags through a timeinterleaved process. In this mode, a shelf-mounted reader in the midst of a counting operation (assigned to 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, for example). A dock door or forklift reader (assigned to Session 3, for example) 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. The output power ranges from 15 dBm to a
maximum of 30 dBm (in .25 dB increments), measured at the Speedway reader's antenna ports.
Channel
North America: 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 and the Channel is factory-set and fixed to frequency
hop.
Europe: A pulldown menu supports channel selection.
Taiwan: The NCC stipulates frequency hopping across the Taiwanese spectrum allocated to UHF RFID (922-928 MHz, with
hopping occurring between 922.25–927.75 MHz in 500 KHz steps). As such, the Speedway reader does not allow the setting of
a static frequency for North American operation and the Channel is factory-set and fixed to frequency hop.

Operation screen has been enabled, the logo of the tag silicon manufacturer corresponding to the TID will also be displayed.
In addition to the EPC and TID, the results displayed include: Read Rate (expressed as tags/sec), Running Time (in hh:mm:ss
from last Start), Total Tags (total number of tags read), and Total Active Tags (number of tags currently in the reader's field of
view).
For more sophisticated inventory operations, the Inventory Filter and Tag Access pages allow the selection of tags according
to user-specified criteria and rules. To access the Inventory Filter, Tag Access or protocol setup menus, any currently executing
operation must be stopped.
6.2. Operation Screen—Filters
If the Inventory Filter has been activated (see Section 6.3), this status will be indicated in the Operation screen view (see Figure
6-2) with the text **Inventory Filter** appearing at the top of the screen. Likewise, if the Halt Filter has been activated (see
Section 6.4), the text **Halt Filter** will appear.

Referring to the set buttons in the lower-left portion of the Operation 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.) only one time (see section 6.4). If the operation is successful (see Last Status column in the primary read
window), the reader will continue the inventory or halt operation, depending on the status of the Auto Continue setting. If the
Act Once setting is not enabled, and the action indicated is a write, the reader will write the tag over and over in a continuous
loop. If 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.
To change settings from Operation mode:
a. Stop continuous singulation using the Start/Stop button
b. Configure the reader to the desired new mode using the Settings, Inventory Filter and Tag Access pages
c. Return to the Operation page and re-start continuous singulation

6.3. Inventory Filter Screen
The Inventory Filter screen (see Figure 6-3) 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 that 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 Mem Bank field specifies if the criteria applies to the TID, EPC, or User
memory of the tag (see Figure 6-4), as follows:
Mem Bank 00 (0): Reserved (cannot select filter on this bank)
Mem Bank 01 (1): EPC
Mem Bank 10 (2): TID
Mem Bank 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.
Note that the Bit Length must be non-zero. As tags are read, the Pattern is evaluated against the Select criteria, which includes
Equal and Not Equal 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.
Figure 6-3 Inventory Filter
In Figure 6-3, the Pattern written is “0xE017FF00431E55550000000000000000, the bit offset is “0x0020”, and the bit length is
“0x0040.” The bit offset for an EPC code must be nonzero because the first 32 bits in the memory map (see Figure 6-4) are
taken up by the CRC and PC codes. Figure 6-5 provides an example of how this pattern would be stored into the tag memory.

6.4. Tag Access Screen
After acknowledging a tag, the Speedway reader may choose to access it. Under the Tag Access menu, a pull down menu
provides five command Actions: Read, Write, BlockWrite, Lock, and Kill.
The menu item Tag Access (see Figure 6-6) 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.
