    I have a twin MAN D2876LE423 with twin digital display MMDS CLC 6.3 / STEP 2 / CR on the lower helm. The upper helm has no digital display and the engines are not connected to the MFD on either helm. I have been trying to figure out a way to get the digital engine displays interfaced with the N2K or at least the MFD on the upper helm so at least I can get basic readings digitally while on the upper helm but every vendor I talk to warns that the data will not copy well into the MFD. Putting new MAN displays on the upper helm is not an option as they are super expensive. I'm wondering if anybody figured out a solution for this issue or what do you guys do on the upper helm? Just rely on the basic data from the analog gauges?

    Don't have two helm stations, and haven't ever seen any reason waste MFD real estate with data that already displays nicely on our CLC displays... so haven't given it any thought.

    That said, if techs suggest data wont transfer nicely from MMDS to MFD, maybe another way around it might start at the senders? I dunno is sensor signals can be split or not, but if not maybe it'd be possible to add basic senders to the engines and route that output to MFD, or even to individual digital gauges?

    That wouldn't be anywhere near like what data is available on the CLC displays, but might at least solve basic stuff like RPM, temps, oil pressure, etc.

    Or maybe you mean you already have analog gauges at your upper helm for that kind of basic info? And just prefer digital display? If so, you could convert those to digital relatively easily. Aetna does digital tachs, CruzPro does digital tach, tank levels (fuel), oil pressure, coolant temp, voltage, etc. Most of those can be a simple gauge swap.

    Or route the inputs that already go to your analog gauges to your upper helm MFD.

    The builder already did, check this out.
    BTW, that's NOT a Mickey Mouse solution - just in case you're not aware, Boening is the actual OEM manufacturer of MAN MMDS displays.

    Nearing the end of the process of replacing all of the analog gauges & switches along with 3 new carbon fiber dipped panels that will be LED back lit. Gave only a little thought to going all digital to MFD's so as to avoid the loss of all Man Engine information in the event of a black-out especially when out of country. Might be old school, but a lot to be said about old reliable.

    Nifty. The EN version of the tech data specifically confirms it supports OP's engines, too.

    I didn't check that, but I think that if the Boening interface can't do what the OP wants, nothing else can.

    In fact, @SplashFl: when you say that you considered replacing analogue gauges with MFDs, do you mean that your MANs are electronically controlled, as is the case with the OP engines?
    I'm asking because if yes, I don't think that analogue gauges (rather than the MMDS displays or the N2K interface connected to MFDs) are any better, in terms of reliability.
    I mean, I've seen several installations with common rail MAN engines where the MMDS display are only at the main helm, with analogue gauges on the flybridge - which is what also the OP has.
    But those analogue gauges are actually digitally driven, (through the two wires can-bus), and they are very diffent from the old school VDO gauges, each connected to its own bulb, that I have in my boat and were also fitted in each and every boat powered by mechanical engines.
    In any MMDS-based installation, I think that any fault affecting the MMDS is also reflected in the analogue gauges, because they are all on the same boat, so to speak... :)

    PS: and if by chance your engines are NOT electronic, I think you have no other choice than replacing the old analogue gauges with something similar, because you have no way to send engines data to the MFDs through N2K - let alone to the MMDS displays.

    Engines fortunately not electronic (VDO gauges except for digital tach's) as no damage was sustained a few weeks back when a lightning storm, which seemed to park near my dock a few weeks back, "only" fried the two ECM's on the Tiara docked next door but no other electronics effected. Previous boat had electronic controls fried when lightning hit another boats antenna two homes west sending bits of fiberglass all over 3 yards but didn't destroy anything else on mine but the boat hit lost all the electronics.

    That's exactly what I was looking for. Thank you.
