2018-08-28 - Version 1.3.7

Bug fixes

  • Fixed potential endless loop in power supply firmware
  • Fixed calculation of cell voltages in cases that the voltages are low

2018-05-15 - Version 1.3.6


  • Measurement > CAN termination: Removed the calibration option. It is now available via Support > Calibration CAN Termination
  • Measurement > CAN termination: Added a visual indication of the measured termination (green = ok, yellow = out of range)
  • Scope: Added "ack start delay" to reports which is the delay between the minimum expected start of ACK until the received start of ACK field)

Bug fixes

  • Power supply: There were problems with the detection of the akku charge level and the akku charging

    • Performance improvements for tracing, especially when using the binary trace format
    • Enhanced the compatibility to older ASCII trace file formats from PEAK-System
  • Revamped the playback section
    • Multiple information about the currently running playback like the current loop cycle and file index are now displayed
    • The playback progress in terms of time and messages transmitted is now displayed with progress bars. The bars are drawn green when the playback is running, yellow when paused, and red when stopped
    • A warning message is shown if a trace playback was paused due to bus errors
  • User defined bitrates are now permanently stored to the bitrates.ini of the project


  • The binary trace file format is now the default file format for tracing, because of its better performance
  • Moved the battery view from the Analog Measurements menu to the new Power Supply submenu in the Support section

Bug fixes:

  • Corrected the handling of CAN frames with 29-bit IDs
  • Corrected the presentation of file lists
  • Multiple issues concerning recording and playback of CAN traffic were solved with the revamp of the trace and playback sections
  • Minor bug fixes and changes of the user interface
  • Multiple issues concerning the charge level presentation were fixed
