ACM100 Firmware Versions

1.1.1.2 (01-24-2020)

  • Support small CT
  • Correctly assign minimum current threshold depended on CT selected
  • Correct calibration process frequency check
  • Fix bug which cause a wrong time reading when timer compare match occur and interrupt was disabled and insert folder name in include header
  • Support Heartbeat PGN (126993)
  • Comply with NMEA2000 version 2.100 certification
  • Change NMEA Certification Level to 2 (As of February 2015 and Version 2.000 of the NMEA 2000 Main Document, Certification Level Field (7) shall be set to 2 meaning “Not Applicable”)
  • Default to use fix phase option (estimate VLL using user configuration instead of fully mathematics calculation) (bug #4348)

 

1.0.9.2 ( 7-13-2013)

  • Changed the default transmit rate of all messages from 100ms to 500ms to reduce network congestion on networks with multiple ACM100's- Added support for resetting the total kW hours transmitted by the ACM100 using the standard NMEA command mechanism
  • Updated the supported NMEA 2000 database version to 2.000

 

1.0.7 (2011-03-15):

  • Add support for 400 Amp AC Transducer with Cable (M000612)

  • Corrected a problem where Line-to-Line voltage measurements were inaccurate in some cases

 

 

1.0.5 (2009-02-23)

  • Improved support for labeling of the device and its channels to store more pertinent information

 

 

1.0.4 (2008-12-05)

1.0.3 (2008-10-21)

  • Changed NMEA 2000 Class and Function Codes to 30 (Power Management) and 140 (Power Management and Lighting Systems / Load), respectively, to enhance compatibility with future NMEA 2000 protocol enhancements

 

 

1.0.2 (2008-08-21)

  • Changed the default node address to 0xC0 to support internal production program
  • Corrected a problem where an invalid damping period value could be programmed into the device

 

 

1.0.1 (2008-07-24)

  • Initial public release
