5.2 Troubleshooting Using the Serial Interface
Communications
To quickly verify serial communications send the
h
(help) command. By sending the
h
and receiving the help menu, the serial communications are verified. If further problems
persist, review Appendix B for more information on communications.
Verify Parameters
To verify the camera setup, send the
gcp
(get camera parameters) command. To retrieve
valid parameter ranges, send the
h
(help) command.
Verify Factory Calibrated Settings
To restore the camera’s factory settings send the
rfs
command. To restore the camera’s
factory calibrated FFC coefficients, first pick the appropriate set (
csn 0
to
7
) and then
send
lpc
to load said set.
After executing this command send the
gcp
command to verify the factory settings.
Verify Timing and Digital Video Path
Use the test pattern feature to verify the proper timing and connections between the
camera and the frame grabber and verify the proper output along the digital processing
chain.
5.3 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 using an internal
signal for synchronization).
Line Dropout, Bright Lines, or Incorrect Frame rate
Verify that the frequency of the internal sync is set correctly.
Noisy Output
Check your power supply voltage outputs for noise. Noise 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.
