Transponder offset returns wrong value

Recommended Posts

Hi!

 

I have a problem with getting the Transponder code from FSX, my code looks actually like this :

Offset<short> TransponderReq = new Offset<short>(0x0354);

FSUIPCManager.ProcessFSUIPC(); //Processing FSUIPC

double  Transponder2 = (double)TransponderReq.Value;
string Transponder = Transponder2.ToString();

And it returns "4608" for the transponder "2406".

It not works with any different values.

 

Thank you !

The encoding for this offset is Binary Coded Decimal which means you need to get the ToString() in hexadecimal, not decimal.

 

If your transponder is showing 2406 then this offset will contain the value 9222. If you convert 9222 in to hexadecimal you get 0x2406 which is what you want.

 

I've no idea why you are getting 4608. This is 0x1200. It might be that the aircraft you are testing on doesn't use the normal FSX transponder. Is it a 3rd party add-on? If so, try with a default FSX plane.

 

This conversion should work:

string Transponder = TransponderReq.Value.ToString("X4"); // X4 = Hex format padded to 4 characters

I was just worried by the Offset description and went in the wrong way, thanks !
