Take a drift scan image


First, connect the camera with the computer using the parallel port.
(or Ethernet adapter or USB if you have a camera with an USB port)
I would not recommend to use the Ethernet interface for drift scan images, except using a focal length < 1000 mm. See also "Settings-Computer".
Then start the program.
If the Camera is not found, check Camera- Settings Computer. It is assumed, that the camera is focused and orientation of the camera is checked, see:
Orientation of the camera
Then start the program.
If the Camera is not found, check Camera- Settings Computer. Settings - Computer
Check all Settings before starting a drift scan image:
Change Time Date: Check Time and Date and Time Zone
Settings Temperature: Check the settings related to the temperature regulation
Settings Information: Fill in some information's to be stored in the file info
Settings Computer: Address of the parallel port, directory to store the images, control image and other settings.
