Ok hey all! Let me set the sceen...
there is an array of 8 (key) switches in one box...
and an array of 8 indicators in another box...
These two boxes are connected Via 20m of Fibre Optic cable.
The idea is by turning on one (or more) of the 8 key switches on box 'A' to have a relivent indicator on box 'B'.
i am thinking in my head some kind of time sharing ccti n box 'A' allowing each key (once energised) in turn to send its own freq down the fibre optic to box 'B'.
Box 'B' will then have a set of 8 filters each tuned to the freq of the relevent switch. once the filter recieves the appropiate freq sig then it iluminates its indicator for a short Time.
I went through and made a basic cct ages ago that was a matter of a few relays and copper lines instead of the fibre but it was just below standard. What are ppls ideas??
Help is really appreciated!!
