Hello All,
I have a CCTV camera and recently obtained a power zoom lens that I would like to use. I would like to make a small controller to control the lens.
The controls needed would be to Zoom In, Zoom Out, Focus Near and Focus Far.
There are three wires that control the above parameters Blue is Focus, Green is Zoom, White is Common. When a positive 9 volt is applied to the Green and negative connected to common the lens zooms to wide, When reversed the lens zooms to telephoto. Same with the focus with positive on Blue for focus near reversed focus far.
I am somewhat new to electronics but able to solder well. I would like to use two rocker switches to control the lens, one for focus and one for zoom. Could someone help in the design of the controller?
Many Thanks,
Randy
