File Access

File Access

The file access interface allows access to the cameras file system.

It provides access to the cameras user set files, LUT files and a user definable file.

Usage of the file access features and registers should not be attempted directly. Instead access the file system through the file access interface of the host application.

There are three user set files (UserSetDefault, UserSet0, and UserSet1). The user set files are treated differently than the other files in the system. When uploaded these files modify the user set setting within the camera. If the user set file is from an older version of the camera or a different model, the user sets within the file are converted to the appropriate user sets for the new firmware. The file is then replaced with the updated user set file. If the file contains user sets that are not appropriate for the firmware version on the camera, they are ignored and discarded. If the file has been modified in any way, the file is discarded and regenerated. UserSetDefault is read-only and cannot be modified.

The UserFile1 is a user definable file.

The SerialPort0 is a file that can be transferred via the serial port.

While a file is open within the file access interface, the camera is not able to start acquisition. Also, the FileAccessExecute command is disabled when the camera is in acquisition mode. Care should be taken to not leave any file open within the camera's file system as it disables the start acquisition register without any feedback as to why.
