I plan on calling Avidyne tech support but does anyone no how they're configured for settings between the IFD440 and GTX345?

I too would like to know.

I have a IFD440 with a Garmin GTX345R and I cant get Wx and traffic. 

Must be somewhere in the settings. I hope.

Because I have a G5 that uses my channel 1 RS-232 out, I can't go right off the config they have on the service information letter. So, I have ADS-B+ (G2) in line 2 out, and my Capstone WX is set in RS-232 channel 4 in.

I'll report back when I get a chance to take a longer flight.

I had a 345 installed and  was at v10.2.0.0.A on the IFDs (I have two 540s).    I was getting ADS-B Position IFD-540 -> 345 and Traffic:  345 ->  IFDs.  But no weather.  

After the 10.2.3.1 install, nothing is working, no traffic, or weather OR GPS.  Transponder showing

"No 1090ES TX".  

I have the settings as follows:

 IFDXXX RS232 output setting: ADS-B+ (G2)…. GTX 345 RS 232 input setting: ADS-B+ FMT 2

 IFDXXX RS232 input setting: Capstone HS Wx …. GTX 345 RS 422 output setting: Optimized Legacy ADS-B    (on this one, the IFD seems to only have "Capstone WX"   (No HS). 

 IFDXXX ARINC429 receive setting: GDL 88 Traffic at High Speed…. GTX 345 ARINC429 transmit setting: Traffic 

I am hoping to fly again tomorrow, and triple check all settings, etc.

I have an Avidyne SkyTrax100 receiver (also called MLB 100) for ADS-B In, and an Avidyne transponder for ADS-B Out. 

My original setup had Traffic coming over ARINC-429 (In 1 set to MLB 100 Traffic) and Weather over RS-232 Input Channel 3 (set to MLB100 Wx). This displayed an older version of of traffic targets that were just small magenta diamonds. Getting traffic over RS-232 would allow more information to be displayed, and even provide speed vectors to the traffic display. It is much nicer than what is available over the ARINC interface. 

I went in and set ARINC-429 data for In 1 to off. I then changed RS232 CHNL 4 In from MLB 100 Wx to SkyTrax Trfc+Wx. This gave me the better traffic display. There were other settings available, like Capstone and the like. You might want to change over from ARINC to RS232 for the GTX345. 

In talking to technical support, I learned that in my system, RS-232 CHNL 2 Output was used to provide position information to my ADS-B Out (an Avidyne AXP-340) and needed to be set to ADS-B(Avi). CHNL 3 Out was used for the ADS-B receiver. It was set to Aviation, but could be changed to ADS-B+(G) if I changed a setting in the receiver too. Aviation is an older format, but seems to be accurate enough for traffic display. 

What I see in all this is that you have to program the IFD to provide position information to the transponder, and you need to select the same format on the transponder side.

You can then transport traffic and weather into the IFD. In my case, traffic was coming over the ARINC429 interface, and weather over RS232. Having both traffic and weather over RS232 gives more information and a more pleasing (to me) traffic display. My understanding is that the use of RS232 for both traffic and weather came with a recent firmware upgrade to the IFD540. Initially, the ARINC429 interface was required. 

Yes, that would be ideal if it would transmit both traffic and weather on the same RS-232 channel, but I don't believe there is a setting for that with the GTX345. I could very well be wrong though. 

My current settings in my IFD:

ARINC 429 in 1: High speed GDL 88 Traffic

RS-232 1 out: Map MX (for G5)

RS-232 2 out: ADS-B + (G2)

RS-232 3 in and out used for MVP50P

RS-232 4 in: Capstone Wx

Current settings in GTX345:

ARNIC 429 out: Traffic

RS-232 in 1: ADSB+ FMT 2

RS-422 out: MX FMT 1

Like I had said in an earlier post, I'm getting traffic on my IFD440, but it appears to be only the transmitted traffic from ground stations, no plane to plane like I get on Garmin Pilot directly from the GTX345. I do not think I'm getting weather on my IFD, but I do have it on Garmin Pilot.

Any help from tech support would be appreciated!

I didn't make any cabling changes. I just turned off ARINC 429 and changed the RS232 CHNL 4 input from something that said Wx to something that said Tfc+Wx. Of course the 345 would also need the correct output setting.

Is there a typo in "RS-422 out: MX FMT 1"? It should be RS-232, right?

 This might not apply to the GTX345. I'm just throwing out how it works on my system, in case it helps. I have no knowledge of the Garmin product.

All Garmin will do to help is say "take out the IFD440 and replace with GTN 650"

If you got them to work i would love to hear about it.  BTW I also have G5 so had similar configuration differences, i.e. use Channel 4 IN for  Capstone HS Wx because 2 Out was going to G5 and Channel 3 going to JPI fuel flow.  Also, I made recommended configuration changes per the version 10.2.3.1 installation instructions .
