Version 1.4.2.0

The application code has not been changed since version 1.4.0.0 at all.

The installer setting has been changed from the previous version 1.4.1.0. The installer setup.exe now installs the application binaries in the same local directory. After the first installation, the application checks if there is a new version on the Internet.

Version 1.4.1.0

The application code itself was not changed at all since version 1.4.0.0. Since this version, every time the application launches, it checks whether a new version is released or not. If released, the user is suggested to upgrade to a new version.

Note: never use this version. The installer of this version has a wrong setting; it tries to install the application based on the files on the Internet, not the local files.

Version 1.4.0.0

This is new version 1.4.0.0! Below are the changes from the previous release (1.3.0.0):

• Added statistics (e.g. number of samples, average, peak-to-peak) to the main screen.

Version 1.3.0.0

This is new version 1.3.0.0! Below are the changes from the previous release (1.2.0.0):

• Reduced the number of digits after the decimal point from 8 to 6 when displaying the current position in mm.
• Improved the GUI responsiveness when the application is connected to the QSB-D.
• Allow the user to select the CSV output path before hitting "Start Recording" button.

Version 1.2.0.0

This new version has changes below from the previous version 1.1.0.0.:

• Configurable connection parameters (COM port name, baud rate, quadrature mode, resolution, zero position count and encoder direction)
• Use the maximum sampling rate of QSB-D (512 Hz = 1.953125 ms) for CSV recording.
• The CSV file does not include absolute time anymore because it is not reliable compared to the 1.953125 ms resolution timestamp generated by the QSB-D.
• Generate a trace log file in the local application data directory to provide more information to the developers when the application encounters a bug.
• "Disconnect from QSB Encode Reader" button to release the COM port without quitting the application.
• Show baud rate, product type (QSB-D or not), serial number and firmware version in the Status textbox when connected to a QSB-D.
• Show application name and version in the Status textbox when launched.
