Specs
- up to 4 devices (2 bit)
- encoder 6(old)7x8x4
- receiver 6x6(old7)x4+1*
- up to 8 devices (3 bit)
- encoder 9x8x4
- receiver 6x10x4+1*
- up to 16 devices (4 bit)
- encoder 11x8x4
- receiver 6x13x4+1*
* the plus one is for the output inverter torch althoug it can be left away.

Encoder/sender
-> configure pulses
-> start button
-> toggles a pulse limiter
-> launch bit release circuit
- send starters pulse
-> start releasing pistons for 1,2 etc. pulses
-> send the pulses in order

Between sender & receiver
- pulses are send over one line

Receiver
->start pulse comes in
-> triggers starters memory cell
-> triggers a pulse shortner for a short pulse opening the memory cell's for the incoming bits
-> opens first memory cell -> opens second memory cell -> same, depends on how many bits you have
- first pulse comes in - second pulse coming in - ,,
->starting compare circuit
-> if onboard: pulse become longer
-> toggles last redstone torch of
-> if correct output will turn on
-> output cannot be on anymore
-> reset circuit launched
-> reset the bits memory cells
- reset the starters memory cell
-> finshid circuit.
