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:
•
•
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.

Chapter 2: Installing and Connecting Speedway/Revolution
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.
