Connection for the "Reference x" Pin .
The simulated sensor is located between pin A and pin C. The reference signals
ca be used to reference the respective channel to an electrical reference potential
of the signal source (e.g. ECU potential).

Connection of the signal lines and the Reference x pin to
an ECU.
Note
The function of the reference pin is given only if noise immunity is observed
during the design of the grounding/cabling concept. (This means, for example,
signal flow with low impedance, defined reference potentials, low transition
resistances, shielded design, no crosstalk).
