Whats the Transponder OFFSET?

[388TH_A]

On here http://www.rvdijk.nl/download/QI_RVD_737NG_XPNDR.pdf whats the Offset if any, also what are they used for? There are 5 positions,

STBY = SWK stby
ALT RPTG OFF = ?
XPNDR = Swk C (Normal)
TA ONLY = ?
TA/RA = ?

Also is there a OFFSET for the Ident Button?

I believe that transponder default of the FS does not simulate these positions that you mentioned. The offset in FSUIPC is 0354, but only of the frequency of the XPDR. I did not find the functions that you mentioned.

Well thats to show the Freq and then i did find 3BE4 as the offset to show when the Transponder failed and it works great. Just would be nice to have a Ident button, Swk Stby, and Swk C as well.

Hi,

FS9 & 10 don't have an offset for the Transponder Mode.
There is an offset for the items you needed, they are provided by IVAO if you want to be an online pilot.
Maybe VATSIM have one too.

From the SDK:

0x7B91 Lenght 1 Transponder Mode charlie = 0 standby = 1

0x7B93 Lenght 1 Squawk Ident

(These offsets work alone with IVAO Pilot client software)

Best regards

Thanks again Jan ill give that a try. And as far as the other things on the 5 position switch im not even sure what the other ones are any ways so guess in the end it doesnt matter. Since on the panel it shows TCAS i looked into the TCAS offsets but didnt really see any thing for the other items listed. But i wont be using a TCAS so again guess i wont need them. Well again thanks ill give thoughs two a try hope they work that would be great if they did then i could get away from the mouse clicks.

in C++ i did that below but seems to half way work... so do you see any thing wrong with this code at all?

		

MkFsObject(FS_XPNDRIDENT,  "OID", EventHandler, 0x7B93, 1, TP_UI8,  FS_NORMAL);


 case C_SXPNDRIDENT:
	if (XPNDRIDENT ==0)
	FsWrite (FS_XPNDRIDENT, 1);
	if (XPNDRIDENT <1)
	FsWrite (FS_XPNDRIDENT, 0);

http://www.squawkbox.ca/doc/sdk/fsuipc.php Shows that SB only reads but doesnt Write the Transponder mode so that would mean that i cant use a knob with this right?

Hi,

what is XPNDRIDENT for a variable???

Try:

case C_SXPNDRIDENT:
	if (val ==0)
	FsWrite (FS_XPNDRIDENT, 1);
	if (val >=1)
	FsWrite (FS_XPNDRIDENT, 0);
break;

[388TH_A]

static int XPNDRIDENT = 0;

is that what your looking for? or..

MkFsObject(FS_XPNDRIDENT, "OID", EventHandler, 0x7B93, 1, TP_UI8, FS_NORMAL);

Is TP_UI8 wrong maybe?

[388TH_A]

Yeah that didnt work i just get a error in the DOS window when i hit the ident button

[sgaert]

static int XPNDRIDENT = 0;
Which code set the 0 to an other value?

You are online on VATSIM/IVAO and check your Output with ATC?
You self see only a small light in the PilotClient, nothing more.

Bzw: If you press and release a button you generate 2 Events, one press (value 0) and two release (value 1).
In the most cases that is not what you whant.
You can only use the press Event by using that code:

case XYZ:
if (val == 0)
{
your code
}
break;
