Read points are powerful RFID sensors that can be mounted almost anywhere to track RFID tags passing through the sensors range. The most common configurations include doorway-mounted portals that track the movement of tags in and out of the room, and ceiling or wall-mounted portals that track the sighting of tags in a particular location.

Model: TS090



The defaults listed here are for an overhead install of the read point, where the desired behavior is to report any tags within it's read range as 'seen'. Terso will provide different recommended defaults if the Read Point is wall mounted, installed at a dock door, being used to explicitly track item removal, or configured in some other novel way to suit your requirements and environment.

The list below are some common, potential LogEntryEvents a read point may send in. However, not all possible LogEntryEvents are listed in this table. The LogEntryLevel in use determines which LogEntryEvents are sent to Jetstream.

LowFlashMemoryLowFlashMemory occurs when the read point has less than 25% flash memory.
LowMemoryLowMemory occurs when the read point 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 read point is started up.


The Read Point does not generate any SensorReadingEvents.
