| Can someone tell me where Avidyne specifies the 429 data protocol between the GTX345 and the 540? |

How does this work if there is an EX5000 MFD in the setup? The 345 needs to talk to it using the same rs422 output port, but with a different format. |

Now I've been approved for posting, what is the purpose of the RS-232 line going from the GTX-345 pin 8 to the IFD pin 57? Thanks, John.

| Mine is wired like that but both ports are turned off so I guess nothing. |

Well, the line from the IFD to the 345 should be for GPS position source for ADS-B. I too have turned off the 345->IFD and haven't noticed anything yet not working but it's also waiting to be flown after the install. John |

So, just to bring this full circle after speaking to Avidyne Tech Support. For 10.2.3.1, the Installation manual has been updated to cover the GTX-345. Below is the wiring:  The settings are indicated as follows:  That should clean all this up. John

Question..... If you don't have the AIRINC line between the GTX-345 and the IFD, does the RS-422 line carry wx and traffic from the GTX-345? If using the setting "Capstone HS Wx+Trfc" would I get both wx and traffic on the display? Is there any difference in the data stream between the AIRINC and RS-422? John PS: My reading seems to indicate that the GTX-345 RS-422 stream when set to "OPT LGCY ADSB" is the GDL-90 protocol...... but there is little information on this.

OK - so I tried to set "Capstone HS Wx+Traffic" as the receive protocol on the IFD and now have both displayed via the RS-232 line. No 429 line required. John

I get traffic over the ARINC 429 line from the GTX 345 In a one hour flight I get the TIS-B with the red circle and slash through it more than I get the traffic It clears itself for a while but then fails again. Anyone know why ?

| Could be that you are not picking up a station, If you are in the middle of nowhere, sometimes mine will go out or say degraded. |
