Introduction:

The MultiReader software from Impinj is a very helpful tool for setting up and testing the Speedway Revolution readers for basic read/write functionality. This tool was created using the Octane SDK and is very easy to utilize for a quick test of a reader.

First, power your reader and connect it to your computer using an Ethernet cable. Be sure to plug the Ethernet cable into the Ethernet port of the reader, not the Console port. Next, download the MultiReader tool from the link provided above and install it to your computer. Once installed, open MultiReader to view the screen as seen below.

Configure the Reader

Next, select Configure Settings to open the Settings menu. Select the "Yes" option in the Control Reader drop-down list and enter the reader's username or IP address of the reader in the field labeled "Name or IP Address". The reader's username follows the format "speedwayr-xx-xx-xx" where "xx-xx-xx" is the last six digits of the MAC Address of the reader. The remaining fields will need to be filled out according to the reader that you are using and the operating region in which the reader will be used. Selecting 'Apply' will apply the settings and attempt to connect to the specified reader.

Additional settings can be found in the categories under the Reader 1 heading in the left-hand side bar. The page titled Modes, RF, Power allows the user to set the reader's Reader Mode, Search Mode, Session, and antenna power. Descriptions for each of these settings can be found on page 39 of the Installation and Operations Guide linked above.

The Field of View page allows the user to modify settings that affect the read field of the antenna. Changing the Population Estimate will help the reader to adjust to higher or lower amounts of tags that should be read in a specific area. The Low Duty Cycle settings allow the user to customize the amount of time the antenna is receiving power as well as the amount of time the antenna is not active.

The GPI Triggers and GPO Settings pages allow the user to configure how the reader reacts to external signal inputs. GPIO functionality requires the purchase of the Impinj GPIO Box (https://www.atlasrfidstore.com/impinj-speedway-revolution-gpio-box/).

The options under the Display page and its child pages allow the user to configure the various display settings of MultiReader. These include the timestamps reported for each tag, the color mapping of tag reads, and the ability to filter tag reads.

The Run Mode page provides the user with the ability to customize the way that the reader inventories tag reads. Using these options, the user can set delays, notification sounds, and run limits. Users can also create a custom set of incremental power steps to test, in order to find the optimal power setting for their tags and environment.

The Data Capture page allows the user to export debug data for troubleshooting. This process is outlined on page 53 of the Installation and Operations Guide.

Reading Tags

Now that the reader has been configured, it is able to perform a tag reading session. Simply press the 'START Inventory Run' button to begin reading tags. Tag reports will be displayed on the screen in the order in which they are read, and will be colored different shades of red that correspond to the amount of time since the last tag read. If a tag moves out of the range of the read zone, the tag report will turn a dark shade of red. Select the 'STOP Inventory Run'  button to stop the read process, and select 'CLEAR Inventory' to clear the screen of the previous tag reports.
