Argonaut SL/SW/XR Firmware

Latest firmware for SonTek/YSI Argonaut-SL/SW/XR.

Changes and Known Issues
12.2 (released 3/2016)
- Corrects Modbus Output "Level" Parameter: The Modbus output of the "Level"parameter in Register 30051 & 30052 was corrected to not include the SystemElevation used in the "Stage" parameter and the flow calculations. It is now simply the water level above thevertical beam as intended.
12.0 (released 4/09)
- Allows new channel types in the internal flow calculation menu option
- Added "Remember Total Volume" feature. Unit continues accumulating flow even if data collection is interrupted. In older versions, the counter was reset to zero if data collected was interrupted.
- Added feature to initiate autonomous sampling in the unit if it is in SDI12 mode and doesn't receive a command from a datalogger. Helps prevent data loss in the event there is a problem with the datalogger.
- Added voltage protection feature. Units used to shut down when battery power dropped too low and would remain down. New feature monitors battery voltage every 2 hts and will reinitiate data collection if levels return to >10V
11.8 (released 5/07)
- Firmware supplied with Argonauts with low-profile housing
- Improved vertical beam algorithms to improve water level measurements, allowed measurements in shallower water
- Required upgrading to ViewArgonaut v3.50 or higher
- Added ability to accumulate flow volume
Do Not Use
- Units with firmware prior to vers 7.0 need to be sent to Sontek for a hardware upgrade

Software/Firmware Status Definitions

Required Minimum: Minimum version required. This version has proven stable and may contain enhancements that are significant over previous required versions

Recommended: Shown to have been reliable and contains features that result in a recommended upgrade over the required version. There could be a few specific use cases where this version may have issues that would result in some users not using this version. If so, those cases will be noted.

Allowed*: Deemed reliable during initial testing. Any issues will be noted along with improvements available over prior versions. Use of allowed versions may be desired in cases when the changes benefit a significant number of the user's conditions or equipment. For example: a new version of software is released that adds support for new hardware. If the user has this hardware, they would need to upgrade to the newer software before it becomes recommended or required. Use of these versions by experienced users will also help OSW identify any unknown issues.

Testing*: OSW is currently testing; any known issues or advantages over prior release will be noted. The use of a version that is in testing should usually be limited to advanced users that can trouble shoot potential issues and provide feedback on any irregularities or problems observed.

Do Not Use: A version either prior to the required minimum or that contains issues that significantly affect operations.

*Note: A version may remain in Allowed or Testing indefinitely. Example: A new version is released while the prior version is still in Testing. In this case the prior version may remain in Testing, while future testing efforts are placed on the newer version.
