Verify Temperature
To check the internal temperature of the camera, use the vt command. For proper
operation, this value should not exceed 75°C.
Note:
If the camera reaches 75°C, the camera will shutdown and the LED will flash red .
If this occurs, the camera must be rebooted using the command,
rc
or can be powered
down manually. You will have to correct the temperature problem or the camera will
shutdown again. If you enter any command other than
vt
or
rc
, the camera responds
with:
Error 09: The camera's temperature exceeds the specified operating
range>
Verify Pixel Coefficients
Use the
dpc
command to display the pixel coefficients in the order FPN, PRNU, FPN,
PRNU… The camera also returns the pixel number for each fifth pixel.
End-of-line Sequence
To further aid debugging, the camera can generate an end-of-line sequence. The end-of-
line-sequence outputs "aa", "55", "line counter", "line average", "pixels above threshold",
"pixels below threshold". To activate the end-of-line sequence, use the commands
els 3
(LVAL extended by 16 (stat) pixels) or els 7 (LVAL shifted by
16 pixels to encompass stat pixels)
. To disable the end-of-line sequence,
use the command
els 0
.
Use the
sut
and
slt
commands to set threshold values between 0 and 255 for 8 bit data
modes, or 0 to 4096 for 12 bit data modes.
8.2 Specific Solutions
No Output or Erratic Behavior
If your camera provides no output or behaves erratically, it may be picking up random
noise from long cables acting as antennae. Do not attach wires to unused pins. Verify that
the camera is not receiving spurious inputs (e.g. EXSYNC if camera is in exposure mode
that requires external signals).
Line Dropout, Bright Lines, or Incorrect Line Rate
Verify that the frequency of the internal sync is set correctly, or when the camera is set to
external sync that the EXSYNC signal supplied to the camera does not exceed the
camera‘s useable Line rate under the current operating conditions.
