My cockpit build Log(WIP)

[bonjourno38]

Hi,

To begin, thanks for your very fast answer. But I have bad news for you, your answers have led to further questions from me .
I have seen the wiring diagrams of a power supply. But I don't Understand something...

-How can I plug the + or - of the power supply to the Revburners !!!!
Because the power supply is sell with an adaptor 2.1mm or 5.5mm. I want you explain that to me, because I'm not a professional in electronics.

-If I wan't to find the good connections on the back of the Dashboard, how can I do ? I should test with a multimeter?

I hope that my English isn't too bad.

Thanks a lot for the creation of Revburners !!!! And for the help you give to me.

Bye.

Hello.
Usually you would connect the power supply to the black connector (DC in the picture) near the usb socket.

But because the power requirements for a dashboard often exceed the Rev Burner's capabilities, the power supply must be connected like in the picture.

In the picture the positive and negative wires from the power supply are connected to the orange screw terminal on the Rev Burner. It is visible in this picture on the right hand side of the board:

Regard finding the connection of the dashboard, I suggest to proceed in this way: first take the 12V and ground wires from the power supply and experiment with the dashboard until it turns on (the fuel gauge will move, some lights will switch on). if you don't have any documentation or manuals the only options is to try avery single connectors until something happens.

Next is the RPM signal from the rev burner. In the Rev Burner configuration screen in SimDash generate a test rpm signal and test every connector on the dashboard until you find the one which make the tachometer move. If it doesn't work try and move the "12V-5V" jumper on the rev burner to the "12V" position. This generates a "stronger" signal for the dashboard.

To the same for the speed signal, using the second rev burner.

I know it is not very scientific but if you have no information about your dashboard there isn't anything else you can do.



Cheers

Hello,

Thanks for your answers, but I have some other questions for you today:

-How can I find the wires + and - of the power supply if there is a 2.1mm or 5.5mm plug ? I should cut the wire before that plug ?
-If I test on all the single connectors, I will not break the dashboard ?
-Can you give me photos of your different installations (particulary the revburners photos and the 156 dashboard) ?

Thanks for your fast answers...  Soon I'll be able to order my 2 revburners With your help fast.

Bye.

Cordially, Florian.

I'd like to offer a few potential answers.

You can find the polarity(+ and -) by using a multimeter.
Set it to volts, stick one test lead inside the plug, and hold the other to the body. If the it indicates a negative voltage, you have the polarity wrong(So switch the red and black leads around).

Most power supplies also have this symbol on the label(without the text):

If yours doesn't, use a multimeter to be sure.

Of course, if you don't have a female connector for the 2.1/5.5mm plug to fit into, cutting it off and connecting the wires directly will work just fine. Provided you're not planning to use the power supply for something else.
Otherwise, if you have a local electronics shop, you could ask them for a 2.1/5.5mm socket. 2.1mm is a common connector, so they'd probably have it in stock.


If you'd like to find out the dashboard connections, try this service manual. I haven't checked because it's a large file, but chances are the connections/pinout are listed in there.

im trying to source a manual for you.

[nescafe37]

here you go.

its 300mb file...
hope it helps

Hello,

Thank you for all your answers, I think I don't have other questions for the moment.
I thank you a lot for your help,  I expect to have the dashboard and after I order my revburners.
If I have other questions, I will post here later...
@Nescafe and Mortos: Thanks for the manual of the GTV.

PS: Nescafe, can you post others photos with the plug on the Revburners ?

A+.

Hello,

I have others questions for you:

-If I use an external 12V, 3A power supply for supply the Dashboard, Should I supply the revburners with other 500mA power supplies via their DC outputs ?
-A power supply 3A/12V does she not give too power for a dahsboard? That is will not to break him ?

Thanks for answers.

Bye.

Great job nescafe looks the nuts. By the way have you seen the wheel adaptor offered by chillicoke? It allows you to fit standard momo wheels on a G25/27. I got one before my rev burners because I prefer the feel of a full size wheel but the other advantage is a full size wheel won't cover your dials... Just wondered if you'd seen it. You don't need to make any perminant changes so you can always switch back if you don't like it. He also does larger paddle shifters if you want these to go with your larger wheel. Google chillicoke and it should come up.

[nescafe37]

yeah i seen them matey and decided to make my own adapter as chillcoke are not cheap

Hello.
Don't connect another power supply to the DC connector of the rev burner. Only use the 12V 3A power supply, connected as indicated in the picture I linked previously

The current rating of the power supply is the maximum current it is able to provide to the dashboard. But the dashboard will only use the amount it needs. So you could use a 12V 3000000A power supply with no problems,  apart from cost.

hey nescafe nice sim u have there, do you mind sharing some measurements or a plan sheet? i want to make another sim like yours very soon.

Thanks Joe

[nescafe37]

sorry buddy but all plans are in my head....basically just made it up as i went along...however i will give you some tips...make sure you get the monitor height correct and make sure you leave enough room to be able to adjust your pedals...

[ORA-Young Joe]

what about the seat height and width of the whole sim and the length that would be help

[nescafe37]

honestly mate you will need to make your own measurements because we are all different sizes and we all have different seating positions
