Motorola CDM 750 CPS Warning Tone question

[Kenyon]

Hi All,

Is there a way to program one of the input pins to have the Motorola play a tone when that input pin gets power or ground? This would be used to warn a driver in a race car when a specific engine parameter has been exceeded (in conjunction with dash lights). The concept is similar to avcomm's warning tone generator: http://www.desertrides.com/forum/viewto ... =16&t=8365

Thanks in advance for the ideas.
