When a new project is created and after BTSensors have been calibrated (see BTSensor Calibration Settings in Motive for BlackTrax), all sensor serial numbers, exposure, gain, threshold, video type, and intensity are saved in the BlackTrax project file, loaded every time the project is opened, and the connection to BTNet is enabled.
When you open a project with a completed calibration file, the saved calibration file is loaded, and Sensor settings are pushed to the BTSensors.
You can also import and load a calibration file manually via the File > Import > Sensor Calibration menu. For more information on importing calibration data, see File Menu.
