Designated Value Signals

Designated Value Signals




Designated values are produced through fixed resistance positions of a multi-position switch. As the switch is operated the voltage drop across the resistor(s) of each switch position causes the voltage level of the input signal to change to a predetermined voltage value.
These predetermined (designated) voltages signal the control module to perform specific functions.

Voltage Values seen as input by control module.




Typical Application of Designated Values

- Cruise Control Switch On E 32
- Seat and Mirror Memory Position Buttons.

Coded Ground Signals






Coded ground signals produce a set of High/Low requests, the combination (pattern) of which is interpreted by the control module to perform a specific function.
Coded ground signals are generated through a switch or series of switches signaling the control module requests for operation.

Typical Applications of Coded Ground Signals

- Wiper Switch
