QSI 500 SERIES USER GUIDE
Status and Notification
QSI 500 Series camera utilizes a variety of methods to inform the operator of the camera's
operation, status and other events. A built-in LED Status Indicator and audible Beeper
provide notification at the camera. In the event of a serious internal error, the camera will
also pass a descriptive error code back to the controlling application which then reports it to
the user.
Camera Status Indication
There is a small tri-state LED indicator on the camera back just above the connector panel.
The LED indicates the current status of the camera and any operation that is underway.
The LED can display green, yellow or red and flash at various rates.
Camera Operational State Indication
Green solid In Idle state, not Busy. Ready to accept commands.
Green flashing USB cable not connected. Not ready to accept commands.
This only indicates that the USB cable is not physically
connected between the camera and computer or hub.
Yellow solid Busy with internal operation. Not ready to accept commands.
This state is seen while the camera is performing power-up
initialization, moving the filter wheel or shutter, or when
uploading an image to the computer
Yellow flashing Upgrading firmware. The indicator will flash rapidly while
downloading the camera firmware and then more slowly as it
is validated.
Red slow flashing Exposing an image. Flashes once every 4 seconds. The
camera can still respond to commands (such as abort image
or read CCD temperature) while in this state.
Note: The Status Indicator can be disabled for the normal camera states
described above. This may be desirable during long exposures where the light
from the Status Indicator may be reflected into the telescope. See the Advanced
Setup dialog box.
Camera Error Indication
Camera error conditions are indicated by a more elaborate sequence of Red and Yellow
flashes of the Status Indicator. Errors are classified as Soft errors or Hard errors. Soft errors
are those that the camera can mitigate, but typically need operator action to resolve. Soft
errors always begin with one Red flash followed by a number of Yellow flashes.
