This video information can be sampled through the serial port by issuing the following
command:
get_line
This command returns a complete line of video (without digital processing or test
pattern) displaying one pixel value after another. It also displays the minimum,
maximum, and mean value of the line sampled.
Use this command to ensure the proper video input range into the processing chain
before executing any pixel calibration commands.
C13 Monitoring the Camera
Temperature Measurement
The temperature of the camera can be determined by using the verify_temperature
command. This command will return the temperature inside the cover in degrees Celsius.
For proper operation, this value should not exceed 75°C.
Voltage Measurement
The command verify_voltage checks the camera’s input voltage and internal
voltages during power-up. If they are within the proper range, the camera returns OK>.
Otherwise the camera returns an error message. Note that the voltage measurement
feature of the camera provides only approximate results (typically within 10%). They
should not be used to set the applied voltage to the camera. The purpose of this test is to
isolate gross problems with the supply voltages.
C14 Rebooting the Camera
The command reset_camera reboots the camera. The camera starts up with the last
saved settings. Previously saved pixel coefficients are also restored.
C15 Setting the Pre-trigger
The command set_pretrigger sets the pre-trigger to a specified integer value in the
range of 0 to 15. A pre-trigger may be required for some frame grabbers.
C16 Setting and Reading FPN Coefficients
The command set_fpn_coeff integer integer sets the FPN coefficient. The first
integer is the pixel number, the second integer is a specified value within a range (see
table).
Number of
Pixels
Value 1 (pixel #) Value 2 (FPN coeff)
512 0 to 511 0 to 511
1024 0 to 1023 0 to 511
