A warning off switch. Specific requirement of the PDA system. With the Bunderson, and I suspect many other vehicles the PDA will be sealed and button function will not be accessible. If the PDA is programmed to supply out of bounds alerts the alerts must be able to be switched off given a toggle switch position. Unfortunately this button cannot be directly accessed by the PDA itself, however insertion of a toggle switch position in the Genboard serial stream would allow the audio warnings to be toggled off.
Requires one digital input.
