What happens when the ADC knob is set to ADC 1?

When the ADC knob is set to ADC 1, data reception occurs solely from ADC 1. This selection isolates the data input to only that specific source, ensuring that the signals being processed or analyzed come entirely from ADC 1 without any interference or influence from ADC 2. This is crucial for scenarios where precise and clear data is required from a specific sensor or data stream, preventing any mixing with potentially conflicting data sources.

The other responses would imply situations where data from multiple sources is mixed or not received at all, which does not apply when ADC 1 is selected. By setting the knob specifically to ADC 1, the system is directed to prioritize and utilize data from this source exclusively.
