9.5 Theory of Operation
The Linear Analog Output Module circuit consists of an embedded microcontroller and associated circuitry.
The microcontroller picks off display data to the display module during the appropriate bus timing cycles and
performs a digital-to-analog conversion by using the external associated circuitry.
9.6 Troubleshooting
Symptom
Possible Cause
µP Failure LED is illuminated
