Basics:
In a bus system the single items are operated via addresses.
Every address only exists once in the system and is permanent assigned to every part.
By sending the address with a corresponding information in digital format the CPU tells the
parts which actions shall be taken.
Additionally the CPU can receive information from the parts (e.g. actual rpm`s).
If two ignition boxes respectively two motors are installed in a unit, the identical parts must
have different addresses. These different addresses are generated by setting a jumper in the
corresponding parts (see pictures above).
