This is one carried over from the old forum
Hi
Not sure why you’d need to design a test circuit but working offshore the easiest way to test a camera is to power it up and plug it into a monitor. This can be done on a bench if you suspect any other part of the ROV system circuits, fibres or wiring.
Camera function control signals can be applied to the correct pins on the bulkhead connector.
If your fault lies inside the camera and you wish to chase logic states or video signals then you’re looking at oscilloscope work and will need a familiarity with the camera or a good set of circuit diagrams. From my experience you probably won’t carry any of the discreet spares anyway.
I have used a device called a Huntron Tracker which is a great piece of kit for component level fault finding. Doubt you’ll see one of these offshore either.
If you open up a camera remember it is housed in a pressure vessel so ensure it is reassembled correctly as water ingress could be rather embarrassing!
Hope this helps.
