Cable Shield Grounding
Camera and frame grabber cable “outer” shields are connected to the CLV-401A
aluminum case. Case and endplate contacting surfaces are unpainted, providing a Faraday
cage to shield internal circuitry. The case is isolated from the CLV-401A circuitry and the
cable “inner” shields, avoiding possible safety concerns.
The camera and frame grabber cable “inner” shields connects to circuit digital ground,
maintaining signal reference levels between the camera and the CLV-401A. and between
the CLV-401A and the frame grabbers.
