Changes since March 28, 2012 to July 1, 2012 - build 352:
• Improved handling of dual synced plates.
• Removed function to get current sync drift since this no longer applies.
• Added functions to check if sync cable connected and resetting of sync values.
• Added code to resolve problems with certain mixes of system USB ports, amplifiers, and devices.
• Other minor improvements.

Changes since August 23, 2010 to March 28, 2012 - build 310:
• Added advanced functionality to control usb thread priority.
• Changes made to support control over the usb timeouts.
• Now supports plates that have calibration matrixes that include + signs as part of the data.
• Error logging in the %TEMP% folder now records more information which will assist in resolving device issues.

Changes since October 28, 2009 to August 23, 2010 - build 300:
• Removed Get/SetAcquirePortReadRate.
• Added ClearPollBuffer to discard current buffered data.
• Added GetZeroLevelNoiseValue for advanced filtering.
• Changed how multiple plates are handled to prevent "stalling" on some systems.
• CoP channel now uses a threshold value for better results.
• Better handling of USB errors.
• Updated to current chipset drivers.
• Improvements to data reading to reduce "lag" on slower systems, noticeably older laptops.
• No longer initializes devices twice.
• Syncing with more than one device now works properly

Changes since October 8, 2009 to October 28, 2009 - build 200:
• Support for new firmware version that mitigates some USB port issues and data interference.
• USB port reading speed has been improved, along with memory and resource management.

Changes since July 20, 2009 to October 8, 2009 - build 194:
• Improved support for more than two synchronized plates, including diagnostic function to get current offset.
• Flow control has been improved
• Support for newest firmware and data checksum functionality.
• Changes in calibration matrix now handled better.
• Improved the startup response time, no longer inits the devices twice on first start.
• New functionality: get last set buffer size.
• New functionality: set and get the low-level read size for fine control of device latency.
• New functionality: able to clear the poll buffer.
• Added JAVA bindings and example code.
• .NET support library updated with TransducerStatus and better event support.
• Updated examples to be more clear and less redundant.

Changes since February 11, 2009 to July 20, 2009 - build 183:
• Improved processor usage when no devices are connected.
• Improved data sequence checking.
• Improved the way fallbacks are done with regards to handling versions of the FTDI chipset.
• Added support for more "generic" FTDI chipsets for wider range of device usage.
• Added support for new firmware that allows for CRC checksum.
• Devices are now always initialized on startup, instead of waiting for them.
• Error logging is done to a %TEMP%\bertecdevicelog.txt file.
• Multiple synchronized devices are now supported better.
• Corrected handling of plates that report more channels than actually exist.
• The usb controller now uses RTS/DTS flow control to improve latency on some systems.

Thank you for your support.
