4.7 Troubleshooting
No Video but the system is running and has power supplied to it.
Listen closely to the PathFindIR II unit when it is initally powered on. If you hear the mechanical
shutter (clicking noise, see section 4.2 "Initial System Startup" on page 17) but the camera does not
produce an image, check the video connections. The PathFindIR II works with most standard NTSC
monitors that have 75 ohm componsite (analog) input.
A proprietary authentication scheme is used between the ECU and the PathFindIR II camera. The
ECU and camera combination represents a matched-pair system which is programmed at the
factory. By design, individual camera and ECU components do not operate on their own or when
paired with other components.
No Video, no clicking.
If video is not displayed and you do not hear a "clicking" sound from the PathFindIR II, check the
power inputs. The PathFindIR II runs on 6V to 16V power through the optional 20 foot standard cable
power leads. If this voltage is exceeded the unit will not function and may be damaged.
The image is cloudy or hazy, or the window has fog or ice built up.
The PathFindIR II is equipped with an automatic heating element which turns on at cold
temperatures. The heater requires a few moments to stabilize the window. Once the window is
thermally stabilized the heating element will turn off automatically.
The image has "lines" or screen door appearance.
Check to see if the image "freezes" or if you hear a mechanical "clicking noise" from the PathFindIR
II unit. If you do not see the image freeze momentarily (this may take a few minutes), the internal
shutter may be damaged. Contact the manufacturer.
The image is shaky.
Check your mounting. The PathFindIR II does not incorporate image stabilization and must be
mounted soundly and securely.
Image is dim.
Check your monitor and video connections. It is recommended that you use separate power
supplies for the PathFindIR II and the local display to make sure you have clean uninterrupted
