Test Pattern
The camera can generate a test pattern to aid in system debugging. Use the command
svm 2
to activate the test pattern. The test pattern is a ramp from 0 to 255DN, then starts
at 0 again. Use the test pattern to verify the proper timing and connections between the
camera and the frame grabber.
3.18 Monitoring the Camera
The camera is equipped with a red/green LED used to display the operational status of
the camera. The following table summarizes the operating states of the camera and the
corresponding LED states:
LED state Priority Camera
Status
Condition
Blinking RED 1 Error Fatal hardware failure
Steady RED 2 Warning Monitoring task failure
Blinking GREEN 3 Progress Lengthy operation in progress

Note: When more than one condition is active, the LED indicates the condition with the
highest priority. Error and warning states are accompanied by corresponding messages
further describing the current camera status.
