We have upgraded the firmware on the Decagon 5TM (V4.00) and MPS2 (V3.86) to help prolong the life of the embedded sensors on the hillslopes.

The main features of the new firmware upgrades:

  1. Only SDI12 addressed as Zero will go to awake state and send sensor read on during initial power on. All other non-zero addressed sensors will go to quiescent mode.
  2. Help sensor be more robust to brownout conditions.

The following dates were the serials of events that occurred when the aforementioned sensors were powered off or on for the upgrades.

  • 2/27/2018 - West hillslope powered off.
  • 2/28/2018 - Center hillslope powered off.
  • 3/1/2018 - West hillslope powered on.
  • 3/2/2018 - Center hillslope powered on.
  • 3/6/2018 - East hillslope powered off.
  • 3/13/2018 - East hillslope powered on.

The 2 attached documents are the full record of firmware updates from notes taken and will be updated as further troubleshooting occurs and an abbreviated version showing only removed sensors
