offsets for SB3 push-to-talks

[NicD]

I've been succesfully using the built-in SB3 PTT function in FSUIPC. However, we now want to hook-up our private-voice-comms (PVT) to a different button which is hooked up to an open-cockpits master card (i.e. not a joystick button). Can't find the offsets for SB3-PTT and SB3-PVT anywhere ... can anybody help out with this?

cheers

Can't recall right now since I'm at work for a couple of days. But one option is to use offset 3110 length4 and control number 1006 wich is for the KeySend command, and then use the parameters in wideclient.ini

[sas550]

There's a reference in the "FSUIPC for advanced users.pdf"

3110 length4

control number 1068 for pvt on

and control number 1069 for pvt off.

Edit: Under the "Additional controls added by fsuipc" there's all the extra fs controls that can be used with offset 3110.

PS. Let me know if you kneed an example of the sioc code.

[NicD]

Thanks for that. Will I still need to set parameters in wideclient with those - or just set 1068, 1069?

If you can send the SIOC code too that would be excellent.

[sas550]

No you don't need to enter anything in wide client. Here's the code (from memory)


Var 0001, name PVT, Link FSUIPC_OUT, Offset $3110, Length 4
Var 0002, name PVT_BUTTON, Link IOCARD_SW, Input 21
{
IF &PVT_BUTTON = 1
{
&PVT = 1068
}
ELSE
{
&PVT = 1069
}
}

Thanks very much for the code - I'll give it a try

Hello Nic,
did you try it - did it work?

I have also drilled two push-to-talk buttons into my yoke-column too, and like to get them to work with the SB3 "PTT On" and "PTT Off" funktion! So: any hints about the appropriate FSUIPC offsets appreciated!

Cheers from the other side of the globe ...

Offset 3110, length 4, control nbr 1001 for on and 1002 for off.

What interface are you using? If you're using a hacked usb stick it's easy. You only assign the function via FSUIPC button page.

Hey, Anders,
thanks for your quick reply!

No, my yoke column (Cockpitsonic) is connected via an USB/Interface to a client computer. This computer is part of a VPN network, where the complete Project Magenta software, FS2004 and SB3 is running. The question is, how to emulate the signal from the button as push-to-talk for SB3 via FSUIPC.

Cheers

This usb interface, does it provide any programming capabilities for buttons/switches?

[flightdeck]

Yes, it is driven by a specific software "Tempest", made by Cockpitsonic as well.
And they promised to amend their programm for me, if I tell them the FSUIPC offset for the RW "Transmit On" and "Transmit Off" command.

We've only done a simple test so far and the offsets work fine. just haven't rigged it up into the sim yet.

In the 737NG there can be 3 PTT buttons for each pilot - 1) on the yoke, 2) on the radio control panel (pedestal), and 3) on each corner of the glareshield (just to the side of the master caution lights). We might configure the one on the pedestal as PTT for private voice.

We learned through experience that it is very difficult for the pilot-not-flying to use the yoke PTT while the pilot-flying is wrestling the beast down the approach ... it's hard to press that PTT when the yoke is moving all over the place in front of you! :)

[NicD]

A further question on this topic... we've finally wired up our 737 audio panels (pedestal) and have the INT switch wired as our push-to-talk for private voice. This is offset 3110 - values 1068 on, 1069 off ... correct ?

Trouble is it just doesn't work. Switch and code are working fine - the values are being sent, but SB just doesn't seem to pick up these commands.

Any clues guys? (Pete ?)
