I heard that Noland Engineering is developing an engine monitoring
system that can interface with sensors / gauges using an NMEA 0183
format, rather than the NMEA 2000 format. I'm not an expert in this
area, so perhaps you should check it out for yourself. I think they
call it a vessel monitoring system. I'm familiar with their
multiplexer and expander products, and they work great and are
reasonably priced.

I think the OP's point was that the raymarine e series accepts the
input from 'standard' NMEA 2000 and displays the stuff on the screen
without the need for another display so you dont need the e80 and a
laptop.

I think the OP's point was that the raymarine e series accepts the
input from 'standard' NMEA 2000 and displays the stuff on the screen
without the need for another display so you dont need the e80 and a
laptop.

I want to use my E-80 to monitor the engines and fuel. I'm also
hoping/expecting that I might also be able to extract at least some of that
same data ot my laptop, currently connected via NMEA-0183. The latter being
something I'd expect might require an extra interface as -0183 is slower
than -2000.

Regardless, I'd prefer to avoid duplicating sensors. The boat's already got
analog gauges monitoring everything but the fuel flow. I'd expect to add
fuel flow sensors, unless the fuel injection/engine management system can
provide this data. But I'd certainly want to avoid attaching all new oil,
temp, rpm and alternator sensors AND their wiring. If it means 'tapping
into' the wires currently feeding the analog gauges that's not an
unreasonable solution, providing it's not horrendously overpriced.

The reason I have both the laptop AND the e-80 is I prefer to layout routes
on the PC and do other work on it. That and the e-80 works better in
sunlight and wet weather.
