MAN MMDS monitors

Ok there are two different issues possible. The display on the helm starts showing all its data in metric units. This can come from a faulty battery for the memory, just like the memory in your car radio that holds all your stations. The display default is metric so when the memory battery goes bad it runs home to Gremany. BUT in some cases a component in the display can fail and cause a large draw on the battery. Just having the battery repalced may not always fix the problem.

Exactly what my port display began doing earlier in the month. 5 quick button pushes on the display puts it back in °F. on re-start, it's back in °C. At least it stays in English!

Hmmm - I almost like Vessel View now....

As to the "runaway hour meter", this is causded by a failed component on the MMDS board that runs the diagnostis system. To be fixed correctly the MMDS boards go back to the manufacturer to be repaird and have a new battery installed also. When they come back they are at zero hours and must be set with the MAN computer and software. Also be aware the gearbox parameters will also be reset to factory defaults, whidh means they will be looking for gerbox sensors. If your boat does not have these sensors you will get an alarm for bearbox temp. and pressure sensor failure.
The control units on the engine are also recording the engine hours so with the MANCATS system the true engine hours can be pulled up and then set onto the MMDS that sends the information to the helm display. Its not a simple case of "just replacing a battery" the battery is soldered to the circuit board and its not something thats standard.

Just know which issue you have so you dont remove the wrong thing and end you spending extra on something that didnt need to be removed. People thing all the time that the display is bad when some issues come from the MMDS board that is in that black box in your engine room. And just know inside that balck box there re a lot os things that could be svrewed up if handled wrong.. Always disconnect the box from power before opening it up.

I can change the battery, and set the engine hours as needed. so, after replacing the battery, all parameters and settings of the gearbox are reset. engine hours are sometimes set not to zero, but randomly. I have a complete project to reset MMDS to factory settings, software to configure settings and cable diagram to connect to MMDS. With this project, you will be able to set the engine hours yourself and restore all MMDS settings. If you are interested please contact.
Ready to configure remotely. I can sell the whole set of software and instructions for performing all operations.
Any MMDS unit is subject to simple repair (battery replacement) and configuration.

Hi Ivan. Maybe you can advise me? I have MAN/Boning MMDS CLC 6.3 which is damaged and probably irreparable.
I can swap for an unused MMDS CLC 6.5. for a low price.
Are the units interchangeable?
Regards Matalex

Hi, can be changed without problems - it's just a monitor

Thank you for your help.
