11.8.4 Connecting an analog gauge or source (0-5Vdc) to the

1. Connect the negative side of the analog source to GND.

2. Connect the positive side of the analog source (0VDC - 5VDC) to one of the 2 digital

inputs.

3. These analog inputs are not designed to detect a signal at high speed. This approach

was adopted to minimize the errors which could be caused by the noise of high

frequencies captured by wiring. The detection of a DC source with a slow variation will

not cause any problems.
