Introduction to Speedway®/Revolution

Speedway®/Revolution (or Speedway/R) is a sta-

tionary, small form factor, UHF Gen 2 RFID tag

reader that provides network connectivity between

tag data and enterprise system software. Built on

the industry-leading quality, high performance,

and excellent reliability of Impinj’s original

Speedway reader, Speedway/R includes a variety

of new features that increase its application flexi-

bility:

• Low Power Consumption

With a low power consumption design, Speed-

way/R can utilize Power over Ethernet (PoE).

Using PoE simplifies deployment and dramatically reduces costs. Speedway/R does

not compromise on performance, however. Even when using PoE, the reader delivers

the full 30 dBm transmit power. Note that Speedway/R supports the IEEE standard

802.3af (for PoE).

• Compact Form Factor

The compact size of Speedway/R (7.4 x 6.9 x 1.2 in) enables ease of installation in

tight spaces and embedded applications.

• Availability of Two Models

Speedway/R offers two models, each with a different number of high performance

monostatic antenna ports. The R220 model is a two-port configuration (shown in the

above photograph), while the R420 is a four-port configuration.

• High Performance Features

Speedway/R utilizes a variety of high performance features making it possible to read

up to 1150 tags per second. These features include Autoset, Low Duty Cycle, dynamic

antenna switching, and receive sensitivity filtering for read zone confinement.

Requirements for Using Speedway/R

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

way/R reader.

Environmental Requirements

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

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

tions

Speedway Revolution Installation and Operations Guide

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 associating RF cable with RP-TNC

male connector interface

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

• an available RS-232 serial port (required only if host system does not support

DHCP)

• Standard, grounded DB9 serial cable (required only if your system does not sup-

port IP provisioning). The Cisco Management Cable (RJ-45 to DB9) is recom-

mended.

• An Ethernet port

• Standard Ethernet cable(s)

Power Requirements

As noted earlier, there are two options for powering your Speedway/R reader: Power-

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

consumption and allows up to +30 dBm. An external power supply allows up to +32.5

dBm.

If using a power supply module, you must use a module with +24 VDC output that has the

following part number: IPJ-A2001-000. Use an AC power cord (for North America) that

has the following part number: IPJ-A2051-USA. You can order this power supply and

power cord from Impinj.

Supported Operating Environments

This section describes the environments in which you can access the Speedway/R 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 con-

nection (RS-232) or Ethernet connection (SSH/Telnet). On PCs running Microsoft Win-

dows, you can now use the same tool—Putty—for both types of connections.

Supported Communication Protocol

For client control of the reader, Speedway/R supports the EPCglobal Low Level Reader

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

cation with the reader and with EPCglobal Generation 2 (Gen 2) RFID tags.

Antenna Requirements

Depending on the reader model you are installing, Speedway/R 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

Regions of Operation” on page 19.

Speedway Revolution Installation and Operations Guide

Overview of Installation and Connection

Process

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

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. Using the MultiReader application, read some tags with your newly-installed reader.

Detailed Installation Procedures

This section provides the details for each step listed above.

Step 1: Position the Speedway/R 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. Also, if you plan to power the reader

using an external power supply, confirm that there is a standard 120 or 220 VAC outlet

nearby. To minimize power loss, it is best to position the reader within 100 meters of its

power source. To learn more about choosing the appropriate location for maximizing the

performance and efficiency of your reader, see the Impinj System Design Guide.

Mounting the Reader

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

To mount the Speedway/R reader:

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

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.

Chapter 2: Installing and Connecting Speedway/Revolution

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

Reader

Depending on the Speedway/R model you are installing, the reader has either two antenna

ports (Speedway R220) or four antenna ports (Speedway R420). Each port is independent,

bidirectional, and full duplex TX/RX (monostatic). It is recommended that you connect

the antenna(s) before powering on the reader.

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

tion Specific to Regions of Operation” on page 19 for a detailed list of approved vendors.

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

way/R requires professional installation to correctly set the TX power for the RF cable and

antenna selected.

To connect the antenna(s) to Speedway/R:

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

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

details on the best layouts for various environments, see the Impinj System Design

Guide.

• 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 19 for the specific requirements for your regularity 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 the connection, making sure it is secure. A loose connection negatively

impacts the performance of the antenna.

Caution: Impinj has designed its antenna ports to be self-terminating. Therefore, it is important that

you do not terminate unused antenna ports. Leave them unconnected.

Step 3: Connect Speedway/R to the Network

You are now ready to connect the installed Speedway/R 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.

Speedway Revolution Installation and Operations Guide

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/R 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 on 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 Speedway-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.

Chapter 2: Installing and Connecting Speedway/Revolution

To connect Speedway/R 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 0.59 or higher contains support for serial connections.

2. Using a standard, grounded DB9 serial cable, 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. Log in with the following default credentials (unless they have been changed):

User Name: root

Password: impinj

7. 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/R” on page 13 for details.

8. 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/R” on page 13 for details.

Speedway Revolution Installation and Operations Guide

Step 4: Power the Reader

You have two choices for powering Speedway/R:

• Power over Ethernet (PoE)

• External 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 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 the table labeled “Reader Operations and Associated Status

LED Behavior” on page 6 for details.

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

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

power supply. If, however, the reader is receiving power via an external 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 supply. Because the external power sup-

ply is capable of higher power than PoE, it always takes precedence if both sources are

connected.
