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 or PRIN, if camera is i n
exposure mode that regulates external signal s).
Line Dropout, Bright Lines, or Incorrect Line Rate
Verify that the frequency of the internal sync is set correctly, or when the camera i s set to
external sync that the EXSYNC signal supplied to the camera does not exceed the
camera’s maximum specified line r ate.
Noisy Output
Check your pow er supply v oltage ou tputs for noi se. N oise present on these lines can
result in poor video quality. Low quality or non-twisted pair cable can also add noise to
the video output.
Dark Patches
If dark patches appear in your output the optics path may have become contaminated.
Clean your lenses and sensor w i ndow s w i th extreme car e.
1. Take standard ESD precautions.
2. Wear l atex glov es or fi nger 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 appr oximately one finger-width
5. M oisten the pad on one edge w i th 2-3 drops of clean solvent—either alcohol or
acetone. Do not saturate the entire pad with solvent.
6. Wipe across the length of the window in one direction with the moistened end first,
followed by the rest of the pad. The dry part of the pad should follow the moistened
end. The goal is to prevent solvent from evaporating from the window surface, as this
will end up leaving residue and streaking behind.
7. Repeat steps 2-4 using a clean tissue until the entire w i ndow has been cleaned.
8. Blow off any adhering fibers or particles using dry, filtered compressed air.
Stuck Bits
If data bits seem to be stuck or do not change, check that the camera is not saturated by
preventing light from entering. To verify the data path integrity, check the levels of the 2
test pattern pixels (first 2 pixels following the last End-of-line pixel. You may need to turn
