I have a trouble with all-sky camera SBIG-340 using my utility. After writing a wrong data sequence into port (starting boltwood's daemon on port, belonging to all-sky) I can't get image: in any image format the first data portion have less bytes than need and after the first data portion transfer stops. All other communications (get version, send commands) works fine. I see that protocol from camera's homepage isn't full. Is there a place, where I can found full protocol description for this all-sky camera? Or at least can someone to clarify, how can I return camera to its original state? Reset didn't help me. I need to run this camera under linux to have ability of raw FITS files archiving (including header with boltwood's data) & posting color image to web page.
