MPRF Temperature, Pressure and Humidity
DataTrace Pro Compatible Firmware:
Revision S - compatible only with DT Pro v1.0
Revision T -compatible only with DT Pro v1.0
Revision 001 -compatible only with DT Pro v1.1
DataTrace RF Compatible Firmware:
Revision B - Initial Product Build
Revision C - For internal use only
Revision D - For internal use only
Revision E - For internal use only
Revision F - Addressed the following two issues:
1. A temperature compensation to the oscillator used for radio transmission and reception has been implemented. This compensation adjusts the operating point of the frequency control circuits inside the radio transceiver to keep the operating frequency close to the frequency associated with the selected channel.
2. Improving the immunity of the MPRF loggers to ambient light, especially light with a high IR content.
MPIII Temperature, Pressure and Humidity
Revision N - Initial Product Release
Revision P - Addressed a known issue with dual-channel (pressure, humidity and dual-temperature) devices.
Revision Q - Added more dual-channel devices to the firmware for compatibility.
MPIII Temperature and Pressure
NOTE: New circuit board design added to MPIII Temperature and Pressure data loggers to address a known failure with the internal clock on some boards at elevated temperatures. At this point firmware revisions were reset to 'A' on this board design. Temperature and Pressure data loggers that are functioning properly with Rev. Q firmware do not need to be changed. The MPIII Firmware Upgrade Utility will detect which circuit board you have and not allow a firmware upgrade to be applied if your logger does not have the newer board.
- Installation package to upgrade your computer's MPIII firmware package. Works with new circuit board loggers only (Revs. B to F).
Revision B - Adapts MPIII firmware to work with new MPIII hardware.(1)
Revision C - Fixed battery reset issue resulting in lost header information.(1)
Revision D - Addressed an issue in Rev. C with data logger communication modes which can cause a data
logger to stop communicating.(1)
Revision E - Addressed an issue in Rev. D that could sometimes create a corrupt header after a battery
change.
Revision F - This change is for internal use only and does not require a field upgrade from Rev. E. Mesa Labs
does not recommend returning the data logger to the factory for this firmware revision change.
(1)NOTE: Please note that if these firmware revisions are found in your inventory they should be upgraded using the MPIII Firmware Upgrade Utility or sent to Mesa Laboratories, Inc. to be upgraded.
