OEM 737-500 IRS Conversion

[Ridgenj]

Hi, I have been doing  simple work with panels with  switches and pots.
Now I want to take next step and try to work on an IRS Display.
Willow has been very helpful.
Does any one knows what I/O card plus extras do I need to convert the Display?
Thanks in advance.
Cheers
Luis

AFAIK you need to be talking ARINC429 to those units.

Many thanks, now I remember that someone  was using Data Information System Protocols in a converted OEM, I think it was a RMI standby unit.
Where to go from here?

Hi Luis,

I am halfway through doing this, i will get some pics and info together and post it later today, teaser photo below

I'm going to talk to mine in native ARINC... I'm not much of a hardware guy, so I do things at the software level!

[Ridgenj]

Wow guys, now I am impressed.  I see some hope in the horizon. I am neither hard- nor software literate, so I am willing to contribute by other means like ordering PCB's etc. I used to get most of my parts from Europe but lately, Leo, Gwyn, Willow and others in A/NZ are fair suppliers. Please PM me to see how can I cooperate, need to see this unit up and running soon.

Cheers

This is actually pretty easy to extract from FSUIPC want you have your displays wired.

Thanks Mike, very nice video and the proof that it works. Now the question is how to get there. What type of I/O cards did you use

Cheers

Luis, I hand wired all my displays. I will log on and send you some diagrams of how to do this. As for I/O, I use the EPIC card. But I can provide you software code that can get you started in the right direction.

Mike,

Are you using LED 7 segments and just the original incandescent N/S & E/W Alpha displays hardwired?

[Ridgenj]

Many thanks Mike, your help is really appreciated. I believe more than one is learning something new here. Thanks for sharing the code too, this will jumpstart my work.

Wow and I always thought that Phidget's had a price but EPIC seems to be above. Anyhow, how many analogs do you use and is also EPIC display needed? I guess you got these cards at a time that alternatives where limited?

Cheers

Luis,

Yes I have 2 display cards as I have several digital displays such as:

Com & Nav, IRU displays, fuel displays, TAT, SAT, Compartment temp displays, APU usage, etc.

As for analogs, many. Ailerons, elevators, steering tiller, rudder pedals, differential braking on pedals, two throttles, two reversers, speedbrake, and trims for ailerons, elevators & rudder. I think thats it.

As for te IRU's, here is my code to drive the displays: Remember this is for Epic but you should see similarities with other I/O software:

In the execution file:

// Pigeon holes and Qprocs


:DisplayLLorWind
{
if(showLatLon)
{
   Display.LonD = lonDeg;
   Display.LonM = lonMin;
   Display.LonS = lonSec;
   Display.LatD = latDeg;
   Display.LatM = latMin;
   Display.LatS = latSec;
}
else
{
  Display.LatBlank = blank;
  Display.LonBlank = blank;

  Display.Windir_speed = windSpeed;
  Display.Windir_dir = windDirection;
}
}

In your definition file:


byte lonDeg;
byte lonMin;
byte lonSec;
byte latDeg;
byte latMin;
byte latSec;

word windDirection;
word windSpeed;

Dear Mike,

One more time, many thanks for sharing your work. I is amazing what you have accomplished here.

Cheers
Luis
