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.
You can send the following commands to a read point via Jetstream.
|Get Device Status||Yes|
|Sync Device Credentials||No|
|Get All RFID Tags||No|
|Restart a Device||Yes|
|Lockdown a Device||No|
|Unlock a Device’s Door||No|
|Get Device Config Parameters||Yes|
|Set Device Config Parameters||Yes|
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 following are the parameters that can be configured for a read point 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.
|AntennaRxSensitivity||The dB receive sensitivity of all of the antennas.||Int||-80||-30||-70||v4.7.2+|

The following are the Jetstream Events that may come into your queue directly from a read point. Other events pertaining to, but not generated by, the read point 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.
|AggregateEvent||Yes||By default, the readpoint 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 read point does not have a pass reader.|
|HeartbeatEvent||Yes||These can be disabled by setting the HeartbeatEventInterval Config Parameter to 0.|
|LogEntryEvent||Yes||These 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.|
|ObjectEvent||Yes||These can be disabled by setting the ObjectEventHour Config Parameter to -1.|
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 Config Parameter determines which LogEntryEvents are sent to Jetstream, the following logentryevents may be sent when LogEntryLevel = Error.
|LowFlashMemory||LowFlashMemory occurs when the read point has less than 25% flash memory.|
|LowMemory||LowMemory 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%.|
|NewFirmwareDownloadError||NewFirmwareDownloadError occurs when a request to upgrade firmware fails.|
|ReadException||ReadException occurs when there is an issue performing an RFID scan.|
|Startup||Startup occurs whenever the read point is started up.|
The Read Point does not generate any SensorReadingEvents.
