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 (incl usi ve 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.

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:

Configuring the Speedway reader for use within existing network environments is done via the
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:

The first parameter to the utility must be the actual IP address for the reader to be used on the network, expressed in dotted­quad 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.

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
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

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.

network device

Set to “Cisco Systems”

2. The active domain name servers on the network, as well as the DHCP lease status.

3. Op tionally, 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.

Antenna

The Speedway reader supports four (4) independent, bidirectional, full duplex TX/RX ports, which must be cabled to their
respective, Impinj-approved anten nas prior to power-up. Each antenna port is labeled (ANT1−ANT4) on the Speedway unit,
and these designations correspond to the
antennas activated by clicking the appropriate button(s) will be operational.

Session

The reader may be assigned to one of four
mode, the use of sessions allows as many as four 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, 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
.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 Im pi n j-a p pr oved 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
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
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.

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 t a gs,
of interest (e.g., a tag that meets the
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.

Tag Access allows the user to automatically Halt the inventory process upon finding a tag
