MVD zero suppression
This document summarizes some information about zero-suppression and which packets are currently "on" in the MVD. Look here to see details of the addressing and packet formats. Look here for notes on setting up the zero suppresion thresholds.
Currently, I have marked all channels as "?" in the "response OK" column because none have yet been tested this year.
