The network for an Impinj ItemSense installation consists of the components that reside within a private Customer Operated Network.
|ItemSense to reader||80||Gateway discovery|
|51505||Reader Agent provisioning|
|22||SSH commands during reader registration|
|Reader to ItemSense||443||ItemSense Agent Protocol (ISAP) for configuration and data/health reporting|
|End user to ItemSense||80||REST API access|
|443||REST API access via TLS|
|161||SNMP v2 requests for reader health monitoring|
|Reader and ItemSense to NTP server||123||Network Time Protocol (NTP) for clock synchronization|
The bulk of the traffic within the customer-operated network consists of the communication between the ItemSense instance and the RAIN RFID gateways, as shown in the following diagram. Although the diagram below shows the IMC and ItemSense core as architecturally separate components, they are currently co-located on the same host.
ItemSense supports the Turbo version of these readers: Speedway R120, Speedway R220, Speedway R420, xPortal, xSpan, and xArray.
The following table summarizes the reader modes and the readers that support each mode.
|Mode ID||Mode Name||Readers|
|2||Dense Reader M4||All models support these modes|
|3||Dense Reader M8|
|5||Dense Reader Two M4|
|0||Max Throughput||All models except Speedway R120 and Speedway R220 support these modes|
|1003||AutoSet Static Fast|
|1004||AutoSet Static DRM|
Readers operate at the 802.11af Class 3 limit for POE power, and require that the maximum resistance of the Ethernet cable is 10 Ohms or less (for 100 meter length cable). For more information refer to the Gateway Installation and Operation Guides on support.impinj.com.
ItemSense is shipped with the latest Octane Reader firmware. All readers should be upgraded to this firmware version after ItemSense has been installed. Readers without the latest firmware show an alert in the ItemSense Management Console, with instructions to upgrade.
The regulatory requirements of a region must be considered when setting a reader's RF power level, mode, and channel frequency. See the Reader Configuration section in the ItemSense Reference Guide for more details.
