Introduction to Speedway® Revolution

Speedway® Revolution is a stationary,

small form factor, UHF Gen 2 RFID tag

reader that provides network connectivity

between tag data and enterprise system

software. Built with the same industry-

leading quality, high performance, and

excellent reliability of Impinj’s original

Speedway reader, Speedway Revolution

offers a variety of new features that

increase its application flexibility:

•Low Power Consumption

With a low power consumption design,

Speedway Revolution is capable of using Power over Ethernet (PoE). Using PoE sim-

plifies deployment and dramatically reduces the costs and greenhouse gas emissions

(GHG) of your RFID infrastructure. Even when using PoE, however, Speedway Rev-

olution does not compromise on performance. It delivers the full 30 dBm transmit

power. Note that Speedway Revolution supports the IEEE standard 802.3af (for PoE).

• Compact Form Factor

The compact size of Speedway Revolution (7.4 x 6.9 x 1.2 in) eases installation in

tight spaces and embedded applications.

• Availability of Two Models

Impinj offers two Speedway Revolution models, with different high performance

monostatic (transmitter and receiver utilize the same port) antenna port configura-

tions. The R220 model is a two-port configuration, while the R420 is a four-port con-

figuration (shown in the above photograph).

• High Performance Features

Speedway Revolution utilizes a variety of high performance features making it possi-

ble to read more than 1100 tags per second. These features include Autoset, Low Duty

Cycle, dynamic antenna switching, inventory search modes that improve tag popula-

tion management, and receive sensitivity filtering for read zone confinement.

Chapter 1: Introduction

• Ease of Use Features

Speedway Revolution uses industry-standard application interfaces, simplifying its

integration with RFID middleware or custom software solutions. In addition, it offers

enterprise-class management and monitoring capability.

• Robust Reader Design

Just like its Speedway predecessor, Speedway Revolution uses a single circuit board

design that delivers field-proven, enterprise-class quality and reliability.

Requirements for Using Speedway

Revolution

This section describes the key requirements for operating and interfacing with a Speedway

Revolution reader.

Environmental Requirements

• Operating temperature: -20º C to +50º C (non-condensing)

• Supported Regions: US, Canada, and other regions following US FCC Part 15 regula-

tions; European Union and other regions following ETSI EN 302 208 v1.2.1 without

LBT regulations

Hardware Requirements

• TCP/IP network equipment, as required to connect the reader to a PC, Mac, or other

network terminal. If you plan to use PoE, you must have either a power injector or a

network switch that supports PoE.

• Impinj-approved UHF RFID antenna(s), including associated RF cable(s) with RP-

TNC male connector interface

• A computer running Microsoft Windows XP, Vista, or Linux PC, which has:

• an available RS-232 serial port

• a Cisco Management Cable (RJ-45 to DB9)—to communicate over serial

• An Ethernet port

• Standard Ethernet cable(s)

Note: To use the MultiReader application (see page 13), you must be running Microsoft Win-

dows XP.

Power Requirements

As noted earlier, there are two options for powering your Speedway Revolution reader:

Power-Over-Ethernet (PoE) or an external universal power supply. PoE offers the most

efficient power consumption and supports up to +30 dBm. An external universal power

supply supports up to +32.5 dBm. Operating at +32.5 dBm requires professional installa-

tion. See “Appendix A: Information Specific to Regions of Operation” on page 27 for

details.

If using a universal power supply module, you must use a module with +24 VDC output

that has the following part number: IPJ-A2001-000. Use AC power cords with either of

the two part numbers: IPJ-A2051-USA (for North America) or IPJ-A2051-EU1 (for

European Union). You can order the universal power supply and power cords from Impinj.

Speedway Revolution Installation and Operations Guide

Supported Operating Environments

This section describes the environments in which you can access the Speedway Revolu-

tion Rshell console (for configuring, monitoring, and maintaining the reader). The tools

you use to access the Rshell console depend on how you connect your PC to the reader:

serial connection (RS-232) or Ethernet connection (SSH/Telnet). On PCs running

Microsoft Windows, you can now use the same tool—Putty—for both types of connec-

tions.

Supported Communication Protocol

For client control of the reader, Speedway Revolution supports the EPCglobal Low Level

Reader Protocol (LLRP) v1.0.1. LLRP is an EPCglobal standard interface that allows

communication with the reader and with EPCglobal Gen 2 RFID tags.

Antenna Requirements

Depending on the reader model you are installing, Speedway Revolution is equipped with

two (R220) or four (R420) monostatic antenna ports (independent, bidirectional, and full

duplex TX/RX).

Antenna requirements vary by regulatory region. For details about the requirements in a

specific region, see the relevant antenna section in “Appendix A: Information Specific to

Chapter 2: Installing and Connecting Speedway Revolution

Installing and Connecting the Reader

Listed below are the primary steps to follow to install and connect Speedway Revolution:

1. Position the reader appropriately for your environment. This may or may not involve

mounting the reader.

2. Connect the antenna(s) to the appropriate ports on the reader.

3. Connect the reader to the network.

4. Connect power to the reader.

5. Test the reader installation by reading some tags.

Detailed Installation Procedures

This section provides the details for each step listed above.

Step 1: Position the Speedway Revolution Reader

and (optionally) Mount the Reader

Choose the appropriate location for the reader. Generally speaking, you should always

keep the unit away from direct sunlight, high humidity, extreme temperatures, vibration,

and sources of electromagnetic interference. Any combination of these conditions may

degrade performance or shorten the life of the unit. Because the Speedway reader supports

Power over Ethernet (PoE), it can obtain its electrical power along with data via standard

cable in an Ethernet network. To minimize power loss, it is best to position the reader

within 100 meters of its power source. Or, if you plan to power the reader using an exter-

nal universal power supply, confirm that there is a standard 120 or 220 VAC outlet nearby.

Depending on your environment, you may need to mount the reader to a wall or another

object.

To mount the Speedway Revolution reader:

1. Locate the four mounting slots on the reader, as illustrated below:

Speedway Revolution Installation and Operations Guide

2. Using 1/4" - 20 or M6 screws, secure the unit. You can mount the reader horizontally

or vertically.

Caution: If there is any chance of dust or water exposure, you should mount the reader so that digi-

tal I/O ports are facing down to prevent ingress.

Step 2: Connect the Antenna(s) to the Speedway

Revolution Reader

Depending on the Speedway Revolution model you are installing, the reader has either

two antenna ports (R220) or four antenna ports (R420). Each port is independent, bidirec-

tional, and full duplex TX/RX (monostatic).

Warning: You must use Impinj-approved antennas with Speedway Revolution. See “Appendix A:

Information Specific to Regions of Operation” on page 27 for a detailed list of approved

vendors. Using any other antenna may adversely affect performance or damage the reader.

Speedway Revolution requires professional installation to correctly set the TX power for

the RF cable and antenna selected.

To connect the antenna(s) to Speedway Revolution:

1. Position each reader antenna, keeping the following points in mind:

• Position the antenna(s) to achieve the most effective and efficient tag reads.

• Position the antenna(s) to maximize operator safety. Personnel who will be in the

area for prolonged periods of time should be able to remain at a safe distance at all

times. See “Appendix A: Information Specific to Regions of Operation” on

page 27 for the specific requirements for your regulatory region.

2. Mount the antenna(s) according to the instructions provided by the antenna manufac-

turer.

3. Attach the antenna cable(s) to the antenna port(s) on the reader. You can choose any

port for any antenna.

4. Finger-tighten each connection, making sure it is secure. A loose connection nega-

tively impacts the performance of the antenna. The antenna cable is properly tightened

when you are no longer able to twist the cable inside the connector.

Caution: Impinj has designed the Speedway Revolution antenna ports to be self-terminating. There-

fore, it is important that you do not terminate unused antenna ports. Leave them uncon-

nected.

Step 3: Connect Speedway Revolution to the

Network

You are now ready to connect the installed Speedway Revolution to your network. You

have two options:

• If your network supports DHCP, you can connect the reader directly to your Ethernet

network and, once the reader is powered, immediately communicate with it via Telnet

(TCP/IP).

• If your network does not support DHCP, you will need to connect a PC directly to the

reader using a serial connection (RS-232), then use the reader’s Rshell command line

interface to configure a static IP address for the reader. At that point, you will be able

to connect the reader to your Ethernet network.

Chapter 2: Installing and Connecting Speedway Revolution

The details of completing each connection option are discussed below. Before proceeding,

however, take note of the reader’s factory default network settings:

To connect Speedway Revolution to the Ethernet network:

• Using a standard Ethernet cable, connect the RJ-45 connector on the reader to a LAN

drop or network switch. A typical network configuration is illustrated below:

If your network switch is PoE-enabled, the reader will power on when you connect it

to the network. See “Step 4: Power the Reader” on page 11 for information about what

to expect.

Note: If you need to connect a PC directly to the Ethernet port, you can use a standard Ether-

net cable. A crossover cable is not necessary.

Table 3: Default Network Settings

Setting Description

hostname SpeedwayR-XX-XX-XX where XX-XX-XX is the last three

bytes of the reader’s MAC address (which is printed on the ver-

sion label attached to the reader enclosure)

DHCP Enabled. The reader also reports its hostname to the DHCP

server.

Speedway Revolution Installation and Operations Guide

To connect Speedway Revolution to your PC over a serial

connection:

1. If necessary, download the latest version of Putty, which is a free and reliable SSH,

Telnet, and serial client. Version 0.60 or higher contains support for serial connections.

2. Using a Cisco management cable (RJ-45 to DB9, available from Impinj with a part

number of IPJ-A4000-000), connect your PC’s valid/active COM port to the serial

port on the reader, as illustrated below:

3. Power the reader and wait for the boot sequence to complete. (See “Step 4: Power the

Reader” on page 11.)

4. On the PC, run the Putty application and select the Serial connection option. Verify

that Serial line to connect to is set to COM1 (if that is correct for your PC). Set

Speed to 115200. Set Flow control to None.

5. Click Open. The Rshell console window opens.

6. Press Enter. The Rshell login prompt appears.

Chapter 2: Installing and Connecting Speedway Revolution

7. Log in with the following default credentials (unless they have been changed):

User Name: root

Password: impinj

8. When the Rshell command line prompt appears, you can begin configuring the net-

work settings for the reader. See “Using Rshell to Configure Network Settings for

Speedway Revolution” on page 12 for details.

9. When you have completed configuration of the appropriate network settings, connect

the reader to your Ethernet network as described on page 9.

Note: If you decide to connect to DHCP after connecting serially, remember to use Rshell to

change the IP address on the reader from static to dynamic. See “Using Rshell to Config-

ure Network Settings for Speedway Revolution” on page 12 for details.

Step 4: Power the Reader

You have two choices for powering Speedway Revolution:

• Power over Ethernet (PoE)

• External universal power supply

If you are using PoE, your reader began receiving power when you connected it to the net-

work in the previous step. Therefore, there is nothing more you need to do. If you are

using an external universal power supply, connect the AC power plug into a suitable 100-

240 VAC, 50-60 Hz power outlet.

In either case, when power is supplied to the reader, it begins its boot sequence. This

sequence typically completes within 30 to 45 seconds. Until the boot sequence completes,

the reader will not accept commands. The Power and Status LEDs on the reader alert you

to what is happening. See Table 2 on page 6 for details.

Important: If a reader is receiving its power via PoE and it detects that an external universal power

supply has been connected, the reader reboots and switches its power source from PoE to

the external universal power supply. If, however, the reader is receiving power via an

external universal power supply and it detects the connection to a PoE-enabled network

switch, nothing changes. The reader continues to receive its power from the external sup-

ply. Because the external universal power supply is capable of higher power than PoE, it

always takes precedence if both sources are connected.

Step 5: Test the Installed Reader

To test that everything is connected and functioning properly, try reading some tags. The

easiest and quickest way to verify operation is by using the MultiReader application, a test

application from Impinj that is useful for quickly configuring various reader parameters

and running simple inventory operations. For details about how to access and use Multi-

Reader, see page 13.

Speedway Revolution Installation and Operations Guide

Chapter 3: Configuring and

Monitoring Speedway Revolution

This chapter provides a high-level view of the configuration and monitoring options avail-

able for Speedway Revolution.

Configuring Speedway Revolution

You can think of Speedway Revolution configuration in two categories: configuration of

the device itself and configuration of the reader’s RF behavior. This chapter provides the

basics for each type of configuration.

Device Configuration

To configure and manage network settings, firmware upgrades, and other device-oriented

operations, you use Rshell, a proprietary command line management interface. This chap-

ter introduces the Rshell commands you are most likely to need when initially installing

and connecting the reader. You can find full details and syntax for all Rshell commands in

the Rshell Reference Manual.

Note: Rshell is designed to be a machine interface. As such, it is always backward-compatible

with previous Speedway Revolution versions. Existing inputs and outputs will never

change. New commands may be added, however, as well as new optional arguments

(which will always be added at the end).

Important: The Speedway Revolution version of RShell is NOT compatible with the original Speed-

way reader.

Using Rshell to Configure Network Settings for Speedway

Revolution

The default configuration settings in Speedway Revolution are often enough to get you up

and running with little to no configuration required. In some cases, especially if you are

not using DHCP to assign IP addresses, you will need to configure a few of the reader’s

network settings.

The following procedure outlines the Rshell commands you may need for connecting the

reader to your network.

To configure the reader’s network settings:

1. Open the Rshell console (see page 10 for details).

2. View the reader’s current configuration settings by issuing the show network sum-

mary command at the Rshell command prompt:

> show network summary

Status='0,Success'

PrimaryInterface='eth0'

ActiveInterface='eth0'

Hostname='SpeedwayR-00-00-B9'

connectionStatus='Connected'

ipAddressMode='Dynamic'

Chapter 3: Configuring and Monitoring Speedway Revolution

ipAddress='10.0.10.41'

ipMask='255.255.0.0'

gatewayAddress='10.0.0.10'

broadcastAddress='10.0.255.255'

3. Configure the appropriate TCP/IP parameters for your environment. The applicable

commands are outlined below:

• Setting Hostname

> config network hostname <HOSTNAME>

• Setting Static IP Address

> config network ip static <IP ADDRESS> <NETMASK> <GATEWAY>

Note that, except for the IP address, the other parameters are optional. If an

optional parameter is omitted from the ip command, its default value is used.

• Enabling DHCP

> config network ip dynamic

• Configuring NTP Servers

> config network ntp add <NTP SERVER ADDRESS>

4. After successfully configuring all required network settings, you can connect the

reader to the network via the Speedway Revolution Ethernet port.

RF Configuration

The approach you use to configure the reader’s RF behavior depends entirely on your

implementation. You may be using a custom software application, middleware running on

a server, or some other approach. MultiReader (see below) is an example of such a client

application. Regardless of the application you’re using, however, the underlying protocol

is the same—Low-Level Reader Protocol (LLRP), a standard, asymmetric, binary proto-

col used for communication between a client application and the reader. LLRP controls

configuration of such things as the antenna transmit power and receive sensitivity, the

mode in which the reader should operate, and more. For details about LLRP, see one or

more of the following documents:

•LLRP Standard: http://www.epcglobalinc.org/standards/llrp/llrp_1_0_1-standard-

20070813.pdf—This document provides the specifics of the EPCglobal-ratified LLRP

standard.

•Octane LLRP (Revision 4.2)—This document provides the details of the LLRP capa-

bilities supported by Speedway Revolution. It also describes the custom LLRP exten-

sions added by Impinj.

• Impinj LTK Programmer’s Guide—This guide, intended for software engineers, pro-

vides guidelines and best practices for working with the LLRP Toolkit. In addition,

software engineers can access language-specific reference guides and sample applica-

tions illustrating the scenarios discussed in the Programmer’s Guide.

Using MultiReader to Configure and Test Speedway

Revolution

Impinj provides a simple, easy-to-use LLRP application for configuring and testing the

basic RF behavior of Speedway Revolution. This application, called MultiReader, is avail-

able from the Impinj support Web site (support.impinj.com). To use MultiReader, your

Speedway Revolution Installation and Operations Guide

computer must be running Microsoft Windows XP. MultiReader is recommended for test

purposes only.

This section explains how to use MultiReader to connect to and configure a reader’s RF

parameters. It also provides a high level description of each parameter.

To configure and test a reader from within MultiReader:

1. Install and launch the MultiReader application. The following screen appears:

2. Click Configure Settings. The Reader Settings screen appears:

3. Connect to the reader by doing the following:

•In Name or IP Address, type the reader’s IP address (or host name). You can

determine the name and the IP address via the Rshell show network summary

command.

Note: The show network summary command will provide the dynamic values returned by

DHCP or LLA if the current configuration is dynamic. The local hostname resolution fea-

ture (mDNS) gives the reader a local hostname in addition to an IP address as its network

Chapter 3: Configuring and Monitoring Speedway Revolution

identity. On an isolated network that lacks DNS service but has mDNS enabled, a reader

with hostname speedway-00-01-02, for example, may be reached using speedway-00-01-

02.local.

•In Model, select the appropriate Speedway Revolution model (either Speedway

R220 or Speedway R420). If you want MultiReader to issue a warning if it detects

a model other than what is configured, select the Warn on model mismatch

checkbox. It is selected by default.

4. Configure a few key RF parameters as described below:

•Under Reader 1 (in the list of readers on the left side), click Modes, RF, Power.

The following screen appears:

•In Reader Mode, select AutoSet Dense Reader. The Reader Mode specifies the

rules to use for communication between the reader and tag. With AutoSet Dense

enabled, the reader automatically senses the environment and adjusts its mode

accordingly.

•In Search Mode, select Dual Target. In Session, select Session 1. Search Mode

and Session work together to control when and how often the reader reads a tag.

Here is a very high level description of how it works: Each tag contains a flag that

is flipped from A to B or from B to A when it is read. The Session value controls

how long the flag retains its value before reverting back to its original value.

Search Mode controls which flag values the reader reads and, in some cases, what

happens to the flag value once the tag has been read. With Dual Target, the reader

reads all the tags with A flags, flipping each one to B after it has been read. When

there are no more A tags to read, the reader reads all the B tags, flipping each one

to A after it has been read. It continues this process back and forth from A to B

and back to A. Session 1 ensures a persistence period that prevents tags from

reverting before they have all been read.

• On the right of the screen is a checkbox for each of the reader’s antenna ports. By

default, they are all enabled. Disable any port to which no antenna is connected (in

other words, deselect the checkbox). Note that leaving all the ports enabled does

no harm, but it does waste processing time because the reader hops to all enabled

ports, verifying the presence of an antenna before attempting to activate it.

Speedway Revolution Installation and Operations Guide

• For each enabled antenna, set the appropriate transmit power (Tx Power) and

receive sensitivity (Rx Sensitivity).

Transmit power controls the power of the signal leaving the antenna—and thus

controls the range of the signal. The optimal setting depends on many things: how

you are powering the reader, the cable length connecting the antenna to the reader,

the number of antennas in the area, the anticipated distance between the antenna

and the tags, and more. For testing purposes, you may want to use the default

value of 30 dBm. Note that the maximum configurable value is 32.5 dBm (if using

an external power source).

Receive sensitivity controls the tag signal threshold below which the tag is

ignored by the reader. This parameter is useful in mitigating stray reads (as stray

tags often have a weaker signal than the tags that are intended to be read). By

default, the Max checkbox is selected, which tells the reader to read all tags,

regardless of the tag’s signal strength (also known as its Received Signal Strength

Indicator—or RSSI). If you want to configure a specific receive sensitivity, dese-

lect the Max checkbox and type the value you want for each connected antenna.

Note that maximum sensitivity is -80.

Keep in mind that, for now, you are simply configuring the reader to test your

installation. You can always adjust these settings later when you begin using the

reader in a live RFID operation.

5. Click Apply. MultiReader displays a progress bar as it connects to the reader. When

the connection completes, the following status appears at the bottom of the applica-

tion:

6. It’s now time to test your reader installation. Place one or more tags in the read zone of

one or more of the attached antennas. Click START Inventory. Tag reads appear in

the large gray area on the left:

In this case, the reader detected five tags. Because the search mode is Dual Target, the

reader continuously reads the tags (first reading the A flags, and then reading the B

flags). Notice in the above image that one of the tag entries is a pinkish color. When a

tag is not being actively read, its entry begins changing to red. For example, if you

were to change the Search Mode to Single Target with Suppression (which tells the

reader to read a tag only once), all five entries would quickly turn red and stay red:

Chapter 3: Configuring and Monitoring Speedway Revolution

So what is the bottom line? If you see tag data appearing in MultiReader, your reader

is most likely installed correctly and its antennas are functioning properly. If you don’t

see all the tags that you placed in the read zone, try moving them to a slightly different

location or placing them in a different orientation.

7. To stop the tag inventory, click STOP Inventory Run.

Monitoring Speedway Revolution

When Speedway Revolution is up and running, you can use Rshell to monitor its health

and performance. This section presents the primary Rshell commands to use for viewing

network and RFID statistics as well as the reader logs. For details about these commands,

see the Rshell Reference Manual.

Octane 4.2 adds support for SNMP and EPCglobal Reader Management MIBs. For more

information, see the Octane SNMP Guide.

Configuring and Viewing Speedway Revolution

Logs

Speedway Revolution uses the standard Syslog protocol to forward its logged events to a

remote Syslog server. The reader also stores the logged events in its filesystem, accumu-

lating and persisting this information across reboots. Logs are classified into three catego-

ries: Management, RFID, and System.

All logged events have an associated severity level. There are eight possible levels which

are listed below in decreasing order from most severe to least severe:

• Emergency

•Alert

• Critical

• Error

•Warning

•Notice

•Info

•Debug

You can configure the log levels you want to see. The reader then retains only the events

with a severity greater than or equal to the configured level. For example, if you choose a

logging level of Warning, then the logs will contain the following levels: Warning, Error,

Critical, Alert, and Emergency.

Note: Regardless of the configured log level, the reader retains all Error level logs (and higher)

in an independent error log.

Use the Rshell config logging command to configure options for the storage and for-

warding of logged events. Use the show logging command to display the logging con-

figuration as well as the actual logged information (in text form). For details about these

commands, see the Rshell Reference Manual.

Viewing the State of the Speedway Revolution

Device

To display information about the current state of the reader itself, use the Rshell show

system command. Using this command, you can view the following statistics:

• A summary of system information—show system summary

• Platform memory usage and available application space—show system cpu

• Generic platform statistics—show system platform

For more details about the show system command, see the Rshell Reference Manual.

Chapter 4: Upgrading the

Speedway Revolution Firmware

Speedway Revolution contains firmware (known as Octane) which you may periodically

want to upgrade. This chapter explains how to manually upgrade a single reader.

In addition to supporting upgrade procedures, Speedway Revolution also provides meth-

ods for reverting its firmware to a previous valid image and for restoring its firmware to

factory default settings. The procedure for reverting to the previous image is explained in

this chapter, while returning to factory defaults is explained on page 23.

A Brief Overview of the Speedway

Revolution Firmware

To minimize downtime and maximize the robust handling of possible upgrade failures,

Speedway Revolution contains dual images of its firmware. When an upgrade is

requested, the reader continues to operate using the primary image while, in the back-

ground, it upgrades the secondary image. When the upgrade completes, the reader reboots

to the new upgraded image, but retains the previous firmware version on the other image.

This approach makes it easy to revert to the previous working version in case there are any

problems with the upgraded image.

Within each firmware image are three individual partitions that logically organize the sys-

tem software. Although you do not need a full understanding of this architecture to per-

form a simple manual upgrade, it is a good idea to be familiar with its structure at a high

level. For a more in-depth discussion of the firmware and how it is organized, see the

Embedded Developer’s Guide.

Following are high-level descriptions of the firmware’s three partitions:

•System Operating Partition (SOP)—The SOP is the primary system partition of the

Speedway Revolution reader. It contains the Linux kernel, the FPGA firmware, the

RFID management software, the reader management software (Rshell), the logging

management software, the firmware upgrade control, the system watchdog software,

and the factory default data.

•System Persistent Partition (SPP)—Files in this partition are automatically gener-

ated and maintained by the software running on the reader. It contains the reader con-

figuration (network settings, LLRP configuration, log settings, and so on), reader logs,

and debug information used by Impinj engineers.

•Custom Application Partition (CAP)—This partition contains custom application

software, other items required by the custom application (extra libraries or tools, con-

figuration files), and custom application logs.

Upgrading the Firmware

Speedway Revolution provides two methods for upgrading the firmware—manual and

automatic. The manual method, which is accomplished by issuing commands from within

Chapter 4: Upgrading the Speedway Revolution Firmware

the Rshell console, is best for upgrading individual readers. The automatic method, which

involves the use of an upgrade configuration file called a metafile, is useful for automating

the upgrade of a large number of readers. As previously mentioned, the focus of this guide

is the manual method.

To upgrade the Speedway Revolution firmware:

1. Obtain the firmware upgrade file from the Impinj support Web site (sup-

port.impinj.com). The upgrade file always has an extension of .upg.

2. Place the upgrade file on a server (http, tftp, or ftp) that is accessible by the reader you

are upgrading.

3. Using the putty application, connect and log in to the reader.

4. From the Rshell command prompt, issue the following command:

>config image upgrade <URI>

where <URI> is the server location and name of the upgrade file.

For example:

>config image upgrade http://usacorp/rfid/reader/image/

OCTANE_4_0_0.upg

>config image upgrade ftp://anonymous:abc@myserver/

ftpdirecotry/image_4_2_0.upg

>tftp://server/sop_3_2_1_RC5.upg

1. After starting the upgrade, you can view the upgrade status at any time by issuing the

following command:

>show image summary

This command provides the current upgrade status, the last operation, the status of the

last operation, and information about the primary and secondary images. You can con-

tinue to reissue the show image summary command if you want to keep an eye on

the upgrade status. Some of the status values you may see are:

WaitingForImageFileTransfer

WaitingForCommitImage

WaitingToActivateImmediate

The upgrade is complete when the UpgradeStatus parameter value is Ready. The

LastOperation parameter should be WaitingToActivateImmediate and the Last-

OperationStatus should be Waiting for manual reboot.

2. Reboot the reader by issuing the following command:

>reboot

Speedway Revolution goes through its reboot process, displaying messages in the

Rshell console as it goes through each stage of the process. When the reboot com-

pletes, the reader login prompt appears on the console and the status light on the

reader is solid green. (See page 6 for details about the LED behavior to expect when

the reader is booting up.)

3. Log in to the reader.

Speedway Revolution Installation and Operations Guide

To fall back to the previous image

1. If you need to revert to the pre-upgrade image, simply issue the following command

from the Rshell prompt:

config image fallback

When the command completes successfully, the reader reboots automatically and

returns to the login prompt.

2. Log in to the reader. It is now running the pre-upgrade image.

Note: If there is no valid previous image, the response to the config image fallback com-

mand is Status=‘8,Permission-Denied’.

Chapter 5: Troubleshooting

This brief chapter presents a few suggestions of things to try if you experience problems

with Speedway Revolution.

Returning to the Factory Default

Configuration

If you are experiencing problems with the reader and are having difficulty pinpointing the

cause, it is often useful to return the reader to a known state (in this case, the factory

default configuration) and try again.

Important: Factory Default Configuration Restore returns the reader configuration to its default state,

but leaves any custom applications installed in the CAP intact. To restore the reader to its

default state AND remove any CAP contents, use Factory Default Restore. See “Warn-

ing:” on page 23.

There are two ways to return Speedway Revolution to its factory default configuration—

issuing an Rshell command or pushing the Factory Default Reset (FDR) button on the

device itself.

To use Rshell to return the reader to its factory default configuration

(leaving CAP intact):

1. At the Rshell prompt, issue the following command:

config image default

When the command completes successfully, it automatically reboots the reader and

returns to the login prompt.

2. Log in to the reader. It is now running with its factory default configuration.

To use the FDR button on the reader to restore to its factory default

configuration:

1. Using an object with a sharp tip (for example, a paper clip), press the FDR button on

the back of the reader (while applying power). When the Power LED turns off, wait

for 3 seconds (while watching the Power LED). When you see the LED blink red once

(this should occur at 3 seconds), release the FDR button. At this point, the reader will

boot up normally.

Warning: Pressing the FDR button for longer than 3 seconds can cause a factory default restore

to occur. Unlike a factory configuration restore, the factory default restore removes

Speedway Revolution Installation and Operations Guide

the reader’s custom application partition (CAP), if one exists, returning the unit to its

state as shipped from the factory. Although there may be situations in which this

removal is necessary, it’s important to avoid accidentally removing the CAP.

The following table lists the factory default configuration values:

Submitting Diagnostic Data for Analysis

by Impinj Technical Support

If Speedway Revolution is exhibiting RF behavior that differs from what you expected

and you are unable to determine the cause, you may want to submit relevant data for anal-

ysis by Impinj Technical Support. Using the Impinj MultiReader application, you can eas-

ily capture data related to the problem scenario (by creating a Reader Diagnostic Data

file), which you can send to Impinj.

Note: An alternative is to create a network trace using Wireshark, a free protocol analyzer that

you can download from the Internet.

To capture data to a Reader Diagnostic Data file:

1. Open MultiReader and connect to the appropriate Speedway Revolution reader. (See

page 13 for details.)

2. Click Configure Settings to open the Reader Settings screen.

3. Verify that you are viewing the connection settings for Reader 1. If you are not, click

Reader 1 in the menu on the left.

4. In Control Reader, select No. This setting value tells MultiReader that you do not

want the MultiReader configuration controlling the reader. Changing this value is

important because you most likely want to capture data for a reader operation that is

being controlled by your application. If, however, you want to capture an RF scenario

that is controlled by MultiReader, set Control Reader to Yes.

5. In the menu on the left, click Data Capture. The following screen appears:

As you can see, Reader 1 is already populated with the IP address. Also note that the

them here. Also note that you can capture data for up to four readers simultaneously.

In this example, we are capturing data for only one reader.

6. Confirm that Capture is set to On.

Speedway Revolution Installation and Operations Guide

7. Click Apply. MultiReader connects to the reader and begins “listening” for any RF

activity. At this point, it will capture data surrounding any RF activity it detects.

8. Perform the RF activity that you want to submit for analysis.

9. When you have completed the activity you want to capture, select the File menu in the

upper left corner of the application.

10. Click Save Debug Data.... A browse window opens.

11. Type a name for the file and save it in the desired location.

12. Send the .rdd file to Impinj Technical Support. For details about how to submit the

file, talk with your Impinj representative or visit the Impinj support Web site (sup-

port.impinj.com). Note that this file contains binary data.

Appendix A: Information Specific to Regions of Operation

Appendix A: Information Specific

to Regions of Operation

Speedway Revolution is designed to work in various regulatory regions. This appendix

includes frequency ranges and antenna requirements specific to each supported region.

Important: For each region, the reader is locked such that it can operate only in the specific frequen-

cies for that region. The region-specific frequencies are listed in this appendix.

Operation in North America

Frequency Plan

The FCC specifies 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). The frequency plan is further explained in the table below:

Antenna Requirements

Positioning

Position the antenna such that personnel who will be in the area for prolonged periods of

time can remain at least 25 centimeters from the antenna’s surface. This positioning is

required by the FCC. For more details, see the following FCC bulletins:

• FCC OET Bulletin 65: Evaluating Compliance with FCC Guidelines for Human

Exposure to Radiofrequency Electromagnetic Fields

Speedway Revolution Installation and Operations Guide

Installation

Because Speedway Revolution is capable of up to +32.5 dBm conducted power on the

housing RF connector, professional installation is required.

Power

Speedway Revolution may only be operated with Impinj-approved antennas and can radi-

ate no more than 36 dBm EIRP per FCC Part 15.247 regulations. The Speedway Revolu-

tion 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 conductor and radiated maximum criteria. The

expression for the maximum reader power setting is:

Maximum power setting (in dBm)

= The Smaller of

(36 - Composite Antenna Gain (in dBm))

(30 + Cable Loss (in dBm)),

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 in the next section.

Operation in European Union

Frequency Plan

For European operation, the Speedway Revolution readers support the frequency plan

listed in Table 8 and is compliant with the ratified ETSI EN 302 208 specification v.1.2.1.

This specification states that no listen-before-talk is performed, the maximum continuous

transmit time on a channel is four seconds, and the reader enforces the 100 ms off time

before reusing the same channel.:

Antenna Requirements

Power

European regulations allow a maximum radiated power of 33 dBm ERP (Effective

Radiated Power) for high power RFID systems. The maximum Speedway Revolu-

tion 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. The max-

imin transmit power of Speedway Revolution is 31.5dBm measured at the RF

antenna port. 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

Warning: The use of any antenna not listed above may damage the reader or adversely affect perfor-

mance.

Appendix B: GPIO Details

Speedway Revolution includes a multipurpose I/O port that contains an RS-232 serial

port, four opto-isolated inputs, four opto-isolated outputs, and a +5V supply. You access

these features through a DE15 connector mounted on the side of the reader.

The four opto-isolated inputs have a range of 0–30V. The reader treats an input of 0–0.8V

as a logic 0, and an input of 3–30V as a logic 1. The reader has a per-input debounce inter-

val that is configurable via LLRP (see the document titled Octane LLRP for more informa-

tion). This value dictates the minimum pulse width of an input. Impinj recommends that

external devices guarantee a minimum pulse width of at least 100 milliseconds.

The reader also provides four opto-isolated outputs. For the GPIO outputs to function, an

external user supply must be connected between V+, and V-. The maximum voltage for

this supply is 30V. When the user configures a selected GPIO output via LLRP to output

logic 0, an isolated FET switch within the reader effectively shorts that output to V- with a

current sink capability of up to 200mA. When the user configures a selected GPIO output

to logic 1, the selected output is pulled to V+ through a 10K resistor. If GPIO isolation is

not required, the reader provides a +5V supply and a ground pin on the DB-15 that can be

connected to V+ and V-.

Figure 3 shows the detailed function of each pin of the GPIO DB-15 connector.

Figure 3: DB-15 GPIO Port

Note: As described above, both the input and output pins are opto-isolated.

Table 9 and Table 10 further explain the function of each pin.
