From my T7-Pro anolog output, I am observing large negative and positive voltage readings.
Puzzled as to why I am observing these voltage, despite the fact that all the power supplies for the external devices that are hooked up to T7 are removed.
Is it possible that a program may be running in the background after I connect to T7?
Your Help greatly appreciated.

What you are seeing is the expected behavior from the analog inputs while they are floating/unconnected:
