Rebooting the Camera
The command
rc
reboots the camera. The camera starts up with the last saved settings and the baud rate
used before reboot. Previously saved pixel coefficients are also restored.
Diagnostics
Generating a Test Pattern
Purpose:
Generate a test pattern to aid in system debugging. The test patterns are useful for
verifying proper timing and connections between the camera and the frame grabber. The
following tables show each available test pattern.
Syntax:
svm i
Syntax Elements:
i
Svm 0
: Video
Svm 1
: DC
DCi = Integer ((i – 1) / 1024) * 24 + 24
Where i = 1 to 8192
Svm 2
: Horizontal
HORi = Modulus (DCi + Modulus (Modulus ((i – 1), 1024), 256), 256)
Where i = 1 to 8192
Svm 3
: Vertical
VERi = Modulus (DCi + FR, 256)
FR = 1, 2, 3, 4, …, 256
Svm 4
: Diagonal
DIAGi = Modulus ((HORi + FR), 256)
Where i = 1 to 8192, FR = 1, 2, 3, 4, …, 256
Notes:
•
When returning to video (
svm 0
) after viewing a test pattern, the camera restores
the saved user settings for set subtract background (
ssb
), and set system digital
gain (
ssg
).
Example:
svm 2
Returning Video Information
The camera’s microcontroller has the ability to read video data when operating the camera in TDI Mode.
This functionality can be used to verify camera operation and to perform basic testing without having to
connect the camera to a frame grabber. This information is also used for collecting line statistics for
calibrating the camera.
