Change log

The LI-8250 updater will install updated firmware for all components in a system.

Version 2.1.4 (current version; released December 12, 2023)

  • Migration to Buildroot.

Version 2.1.2 (released April 27, 2023)

  • Support for version 3 printed circuit boards. Adds support for power sequencing the an internal temperature sensor. No changes to the interface or operation.

Version 2.1.1 (released January 13, 2023)

  • Support for an updated System-on-Module (SOM), the components of the embedded processing system. No changes to the interface or operation.

Version 2.1.0 (released February 14, 2022)

  • Interface v1.5.2
  • Multiplexer firmware v2.1.0
  • Extension manifold firmware v1.0.11
  • Chamber firmware v1.1.7

New Features

  • Added support for the flask sampling kit.

Bugs Fixed

  • Set limit for pre-purge to 5 seconds and post-purge for 0 seconds.
  • Resolved issued with manifold valve state when loading configuration page in the interface.
  • Improved reporting of chamber status.
  • Added 15 second delay after a measurement is aborted due to a flow restriction.
  • Improved system performance following multiplexer reboot scenarios.
  • Truncated significant digits after a decimal to 2 characters in the interface.
  • Improved communication between the LI-870 and multiplexer (changes to the LI-870 firmware).
  • Improved detection and display of trace gas analyzer nodes.
  • Improved performance of connection when a computer is reconnected to the device network after being connected to a different network.
  • Improved alignment of Stevens Probe SDI-12 measurements with other chamber measurements to avoid missing soil water content and temperature data.
  • Additional refinements.

Version 2.0.0 (released December 3, 2021)

  • Added support for extension manifolds.

Version 1.2.5 (released March 17, 2021)

Embedded firmware

  • Now continues to track chamber status beyond end of measurement

Interface changes

  • Shows correct number of files found
  • Fix chambers expanded state in diagnostics page
  • Fix some color inconsistencies
  • Refactor tool-tips
  • Add files error dialog to deletion and copy on USB operations

Chamber changes

  • More gracefully handle a close limit or open limit sensor failure
  • Cache measurement set configuration info while SDI-12 device is performing measurement
  • Report -9999 for SDI-12 fields that are not reported by device due to a misconfiguration
  • Does a full SDI-12 measurement reinitialization on start command even if already in measurement mode
