RFID Surface Read Points are used to track inventory and transactions. It's sleek, rugged form factor and ease of install allow it to be used in a wide variety of environments where a RFID read point is desired. Common applications include tracking two-bin kanban systems for consumable inventory, or as a check-in/check-out station.

Model: TS082


You can send the following commands to an RFID Tray via Jetstream.


The following are the parameters that can be configured for an RFID Tray via policy. Available parameters may differ by firmware version. To configure your own devices via Jetstream, follow this guide. Terso Support can also manage these configuration settings for you.

The following are the Jetstream Events that may come into your queue directly from an RFID Tray. Other events pertaining to, but not generated by, the RFID Tray are not listed here as those Jetstream-generated events do not vary by device type. See the Event entry in the Glossary to see a complete list of which events are from a device and which come from the Jetstream application.




AggregateEventYesBy default, the RFID Tray will only return "Adds" in it's aggregate events. "Removes" can be enabled by setting the RemoveEvent config parameter to 1. PassRFID parameter will always be blank, since the RFID Tray does not have a pass reader.
HeartbeatEventYesThese can be disabled by setting the HeartbeatEventInterval Config Parameter to 0.
LogEntryEventYesThese can be disabled or increased by configuring the LogEntryLevel Config Parameter. Disabling LogEntryEvents is NOT recommended, as this would prevent you or Terso from remotely monitoring the health of the unit. See the LogEntryEvents section below for more details.
ObjectEventYesThese can be disabled by setting the ObjectEventHour Config Parameter to -1.


The list below are some potential LogEntryEvents an RFID Tray may send in. However, not all possible LogEntryEvents are listed in this table. The LogEntryLevel Config Parameter determines which LogEntryEvents are sent to Jetstream, the following logentryevents may be sent when LogEntryLevel = Error.

LowFlashMemoryLowFlashMemory occurs when the tray has less than 25% flash memory.
LowMemoryLowMemory occurs when the tray has less than 25% memory. This event will be sent every hour until the device reboots. Reboot occurs automatically if memory drops to 10%.
NewFirmwareDownloadErrorNewFirmwareDownloadError occurs when a request to upgrade firmware fails.
ReadExceptionReadException occurs when there is an issue performing an RFID scan.
StartupStartup occurs whenever the tray is started up.


The RFID Tray does not generate any SensorReadingEvents.
