The maximal wire length is limited by the resistive loading to the maximum wire resistance
divided with the wire resistance per length of the unit.
The maximal wire length is limited by capacitive loading to (100nF - external capacitive
loading) divided with the wire capacitance per length of unit.
R
is resistance for the complete wire.
