In light of a request by TAGERT and other device link users concerning this issue I am starting this thread on Device Link. I am starting it here because it a technical issue and also this board has a smaller number of stickies...
Please limit your posts here to specific questions or tips concerning device link. All superfluous posts will be deleted. What I would like, before any posts really get rolling is for all those who either use it or are familiar with it to post here the what, why and how of the tool. This Device Link FAQ thread will be 100% user built from the ground up so if it flies or dies it will be up to the Device Link users themselves. If you see something that has already been said no need to repeat it... occasionally I will trim the thread to keep it as to the point as possible. Thank you all for your cooperation ... and let the thread begin.... |

First a little DeviceLink discription/summary. The initial and/or real purpose of DeviceLink is to provide the home build cockpit guys with a way to send and receive data to/from IL2-PF. DeviceLink is the gateway between the real world gauges and levers and the simulation world gauges and levers. With your own hardware and a little software you can read out the simulation altitude via DeviceLink and use it to cause the real altitude gauge in your home build cockpit to display the altitude. You could also have a switch on your home build cockpit that is used to raise and lower the landing gear. In short, you could have a gauge and or lever in a home build cockpit to control just about everything in the simulation.
That is the initial and/or real purpose of DeviceLink, but there is an added benefit to DeviceLink. You can capture all that data to a file. Then look at (plot) the data to see what is actually going on as opposed to what people *think* is going on. This comes in very handy to see if a bug is a true bug, or just another case of the user misconception of what was actually going on. My first contribution to this thread shall be a cut-n-paste from a post by lurker_hlb3 that tells you step by step how to install and setup UDPSpeed. The UDPSpeed program works in real time to display these values to the screen and/or save them to a file. UDPSpeed also works during playback of track files! Which comes in very handy during testing. There are other progams out there that interface with DeviceLink. But, UDPSpeed is a good place to start.

Bearcat......ty very much for this. Tagert...a veruy good start with UDPSpeed. Let everyone be aware also that another program is out there called UDPGraph which is far more flexible. It can be found in that same article at SimHq just farther down the thread. Also......everyone be aware that UDPSpeed and UDPGraph only work offline. No one ahs found a way to make it work online yet that I know of.

Yes Thanks Bearcat!! I was going to include it, but the link to UDPGraph looked dead? http://www.avcsite.ru/il2dl/graph.htm That and I didnt have a good step by step on how to set it up. I never really looked into that too hard.. I know the reasoning is that some consider it a cheat.. that and it supose to put a little burden on the server.. But, I seem to recal that *if* the server enables DeviceLink that *some* of the info will work.. but not all. I dont recall which do and dont.. Does the DeviceLink doc address that? Anyway, I have to admit, I personally dont care about spinning any guages on a home build cockpit! But some do, my only real interest is in proving and disproving bugs! PS if anyone has a full up version of UDPGraph that they downloaded before the sight went down I could host it for dl on my page. |

Would it be possible to get slipindicator working with this UDBspeed gadget?
Would be nice now when trimming is so essential. "Enemy fighters at 2 oâ´clock!" "Roger! What should i do until then?"! |

Would you guys like a Device Link Chapter in the IL2 CC Manual?
I could also expand the FAQ to include device Link IL2CCM |

Also...yes if the server enables DeviceLink parts of it will work but not any of the really good stuff. I think it was jsut a couple functions that would work if any at all. of use. |

Snoopy...I think that would be great. Lets try to get all our ducks in a row with all the available programs and setups then post it. |

PS where is BaldieJR? I thought he was big into this stuff? Im sure he would have some good input to all this!

That would be cool! But, we also need a forum where guys can get togther and share info, lessons learned and new ideas.. Which in turn could be folded back into your FAQ page as we learn them. |

This is link for UDPGraph:

Does anyone know how to reliably obtain true airspeed from UDPGraph? The utility includes two functions. One requires IAS and altitude as parameters. The other requires IAS, altitude, temp, and pressure at sea level.
The stumbling point for using the second function, which I assume is more accurate, is of course temperature. I am not sure if the function requires another function that to adjust the temp with altitude or not. Anyone know how these functions work in UDPGraph?

You could use the temp equation I came up with for temp on the Crima map, as for pressure, not 100% sure. But the simpfied version of the TAS is problly good enough for most of what we do. In that temp only effects the IAS to TAS conversions during extream temp changes. Since Crima is supose to be close to the standard day.. the simply convesion should be fine. Why do you ask by the way? Does that energy method require TAS? Keep in mind that the wonder woman view does display TAS.. But.. Dont put too much credit in that display just yet.. We found some errors between TAS and IAS at sea level on the Crima map.. And if the Crima map is close to the standard day, then there should be no difference between TAS and IAS at sea level.. So something is a miss here. Just not sure what it is yet. |

Sorry for taking so long but here is a forum for Device link:Device Link Forum
and the beginnings of a device Link section in the IL-2 Online manual: IL2CCM Device Link I will be using material from this thread and the Device Link Forum in the Manual so if anybody objects to their material being used please say so. |

COOL! As for objections! None here! I consider it an honor to be quoted at your sight! In that it is the best flight sim sight in town imho! |

Ive had a request for udpspeed, if anyone has it please upload to submissions and I can make it available.
Forum is still alive |

Trouble in the whole story is that I can't find UDPspeed anywhere to download.
http://www.barans.ru/upload/alezz/UDPSpeed/UDPSpeed.zip don't work for me. I can download UDPgraph instead... but since I don't have much experience with this type of programs I figured that it would be better to use UDPspeed if I could find myself one.

I would use UPDGraph, it is easyier to set up and can graph variables in real time while your flying |
