By sending the hand receiving the help menu, the serial communications are verified. If further problemspersist, review Appendix B for more information on communications.Verify ParametersTo verify the camera setup, send the gcp (get camera parameters) command. To retrievevalid parameter ranges, send the h (help) command.Verify Factory Calibrated SettingsTo restore the camera’s factory settings send the rfs command. To restore the camera’sfactory calibrated FFC coefficients, first pick the appropriate set (csn 0 to 7) and thensend lpc to load said set.After executing this command send the gcp command to verify the factory settings.Verify Timing and Digital Video PathUse the test pattern feature to verify the proper timing and connections between thecamera and the frame grabber and verify the proper output along the digital processingchain.5.3 Specific SolutionsNo Output or Erratic BehaviorIf your camera provides no output or behaves erratically, it may be picking up randomnoise from long cables acting as antennae. Do not attach wires to unused pins. Verify thatthe camera is not receiving spurious inputs (e.g. EXSYNC, if camera is using an internalsignal for synchronization).Line Dropout, Bright Lines, or Incorrect Frame rateVerify that the frequency of the internal sync is set correctly.Noisy OutputCheck your power supply voltage outputs for noise. Noise present on these lines canresult in poor video quality. Low quality or non-twisted pair cable can also add noise tothe video output.
