I'm an Opticodec-PC SEE user and I wonder if it could be started on and off automatically?
No, the Opticodec-PC SEE doesn't support automatic on or off. I have checked the website and the user guide, but I couldn't find anything related to On/Off procedure. There are, however, other automatic features available in the software like automatic reconnection when the line drops.
For more information I recommend checking the following manual: ftp://www.orban.com/1010/Documentation/Opticodec-PC_Manual_(eBook).pdf
