One might be able to get a rate converter to work, but that feels like a science project.

115200 will be supported in a future release.

Then that may well solve that one issue, connecting to both an ASPEN & IFD.

Great news Simpson.   Thanks.

PS - Which of the NGT serial rates does the IFD presently support?  I didn't see it in the Installation Manual - is it in there?

Does anybody on forum have experience and/or photos of 
        GTX345 displaying ADSB Traffic & Wx on the 540's?

Also, assuming GTX345 does play with our 540's, will the 540 internal WiFi allow:
  .  ADSB Wx ADSB Wx downloads to iPad Apps?
  .  full 540 Apt Info integration  - like Density Altitude etc.

Thanks.

Progress on the 115.2 baud rate? Yes, still slated for an upcoming release.

It was a little confusing in the 10.2.1 thread: Is the NGT-9000 TIS-B and FIS-B data feed supported or not?

My IFD540 has been displaying TIS-B and FIS-B weather from my NGT-9000 since 10.2.0 was installed.  I have some missing blocks sometimes in the nexrad but I am hopeful that the baud rate increase in 10.2.1 resolves that.

It takes some tricks to make this happen (the NGT's output is RS422, and the IFD has no RS422 input, from what I recall), but this forum has discussed how it's possible to wire it up to make it happen.  Yours is the first post I've seen that indicates the work-around actually works.  

Do you get the full ADS-B traffic symbology the NGT-9000 provides on its own display, also displayed on the IFD540, or just the simple traffic icons?

I did the 10.2.1 for a customer today. He had aspen, ngt900, and ifd540. Prior to today, he had wx and traffic on aspen from ngt9000, nothing on ifd540 because of baud rate conflicts. Now, with 10.2.1, we changed the format to capstone HS wx and traffic. The ngt9000 data feeding the aspen now also feeds the ifd540 and seems to work properly. I verified traffic, metars, winds aloft, there was no actual nexrad near me to see, but the shaded out lines weren’t there, so I’m guessing that’s good also. The owner will fly it soon and give me a report, but I think it’s good!

By the way, the speed on the ngt9000 is 115200 for the aspen, so it is high speed which hopefully will provide better thru put.

OK, it's official now. What do I need to do to get full functionality display on the IFD540?

Running 10.2.1 right now. Looks like installer configured the TIS-B data on the ARINC429 connection. Is there a specific NGT-9000 firmware version required? Does it require RS-232? Should be able to just move pins on both boxes, correct?

There is not any upgrade or minimum version required on the NGT-9000.

The NGT-9000 sends traffic only out its ARINC429 port; it sends both traffic and FIS weather out its RS-422 port.

Only requirement is that the NGT-9000 RS-422 out be wired in a particular way to the IFD-540 RS-232 in.  Then the settings on each device for their respective ports are set to 'high speed'. 

I am not an installer.  The ability to set the IFD's baud rate to the 'high speed' setting did not exist until version 10.2.1.  Leave the details to your installer.

And, there is a $$ promotion on right now, for the 9000 + IFD.

Thanks for the information Alex. As a firmware engineer of 30 years with a BS+MS in EE, leaving the details to the installer is not an option. :-)
