4 AUTOSTAR CCD PHOTOMETRY
The AutoStar Envisage window will then open (Fig. 2-2). After a
few moments, if there are problems and the camera image doesn't
show up, check the USB connection to the DSI camera. You
should use a powered USB 2.0 interface, even though the DSI
camera will work marginally with USB 1.0. If problems persist, try
another USB cable. Note: A maximum length of 12 to 16 feet (3.5
to 5 meters) is recommended for the USB 2.0 cable connection to
the DSI camera.

(Camera Not Connected or Inoperative).
Figure 2-2 shows the AutoStar Envisage default window, the one
that displays when the camera is not recognized (not connected or
has a problem). This is easily identified by the "Add" and
"Remove" buttons at the upper left. When the camera is connected
and all is working, those are replaced by the "Gain" and "Offset"
sliders. (Also note that the window showing the camera image is
blank.) It may be necessary to re-connect the USB cable and
camera to a specific USB port, in order for the device to be
recognized.
