Series subfolder - created automatically Files limit in a subfodler - number of files stored in a subfolder inside Series subfolder CF card device name - GPS/IMU log is saved to the internal CF cards. On the master camera they are /dev/hda1 & /dev/hdb1 GPS/IMU log file name - absolute path (in the master camera)+ log base name Starting index - logs are named as follows - [base_name]-[index] Records per file - number of records per log file. New file: an incremented index is added to the base name.

HDRVexpos - in the HDR mode - the darker frame multiplication coefficient to get exposure for the lighter frame. AutoExp max, ms - the autoexposure value limit.

Note: Missing files most likely means that the FPS is too high.
