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.
6.3 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). Unused signals in the cable should be termintated in 100
Ω.
Line Dropout, Bright Lines, or Incorrect Frame 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 frame rate under the current operating conditions.
Noisy Output
Check your power supply voltage outputs for noise. Noise present on these lines can
result in poor video quality.
Dark Patches
If dark patches appear in your output the optics path may have become contaminated.
Clean your lenses and sensor windows with extreme care.
1.
Take standard ESD precautions.
2.
Wear latex gloves or finger cots
3.
Blow off dust using a filtered blow bottle or dry, filtered compressed air.
4.
Fold a piece of optical lens cleaning tissue (approx. 3" x 5") to make a square pad that
is approximately one finger-width
5.
Moisten the pad on one edge with 2-3 drops of clean solvent—either alcohol or
acetone. Do not saturate the entire pad with solvent.
