I want to design N number circuit, Two transmitter/receiver are
matched, No other should be able contact this dedicated pair, N number
should be self identifyable/programmed.
Please give circuit/parts and other details.
Thanks

What is being transmitted? (data, button pushes, prescence)?

Over what medium? Hardwire, optcal, RF, sound?

Is a micro an option? Ready to go IC? Discretes?

Will it need field programmable (dip-switches, eeprom, computer
programming, handheld programmer?

How many unique units?

Is there any security concerns? (as in possible cloning or monitoring of
transmitter unist?


Well no matter what it is, I'm *sure* it can be done with a PIC.
