New (to me) boat with some older electronics integrated with the MFD via the N2K connection. Some of the "sensor list" items on the MFD do not align with the tags e.g. an older Airmar Smart Tri Multisensor is listed as an DST 200 when the label on the transducer has an Airmar part nr that equals a DST 800. Is my MFD reading the connected equipment ID thru PGN 126996? Is there a way to read a specific PGN without special gear?
