Hi Kent,

Walt is correct that the GTX23ES is designed to connect to a GSU25 ADAHRS in a G3X/G3X Touch system, so can't be used without one of these systems.

The GTX23ES is $2,199, which is a great price, but a quick search turns up street prices under $2,900 for either the panel mount GTX 335 or remote mount GTX 335R which will interface to your GTX 650 and provide ADS-B Out.

Let us know if you have additional questions.

Thanks,
Steve

I got my new GTX-345 up and running. Love it. Seeing all of the traffic is eye opening (Pun intended). I have it paired up with a GNS 430W and the Flight stream 210.

Only bump in the process was figuring out my com port on the 430W was inop for receive. I could receive flight plans on the IPad, but I could not send them to the GMS. The 430 also had some other minor issues, so off to Garmin for refurb (Ouch$).

I did go with the Garmin pressure transducer for the encoder. My EFIS was feeding the previous transponder and I wanted to free up a com port for other things.

Thanks to the Garmin experts and Stark Avionics for help trouble shooting.

Don't forget, if the encoder or altimeter has been replaced, a Data Correspondence Check must be accomplished to ensure the altitude data transmitted to ATC corresponds to within 125 feet of the altimeter normally used to maintain flight altitude per CFR 91.217.

With an EFIS feeding the xpdr this data always matches, now with a seperate encoder both units (alt & encoder) must be checked to be sure they match (makes the IFR cert a bit more trouble).

Thanks Walt. I have the IFR cert schedule as soon as the radio gets back from Garmin. **** poor planning on my part, just had the cert done in March.

I finished the install of a Garmin GTX 345 on my RV8 equipped with an updated Garmin GNS 430 W and an AFS 4500.

I replaced a Garmin GTX 327.

I'm using the same altitude source for the 345 that I was using on the 327, specifically, pin 13 from the AFS 4500 which I believe is an ICARUS device. My GTX 345 RS232 port 3 for altitude is configured in accordance with the installation manual (ALT FMT 1-100).

When I set my EFIS barometer to 29.92, the altitude on the EFIS and the GTX match exactly, as they should.

Question: Do I need to have a shop conduct a Data Correspondence Check?

My last check (GTX 327) was conducted February 2014.

Thank you!

Hi. I see a 345 Remote transponder, could these transponder be controled from the g3x GDU370 or only on GTN?s?

Hello Hernan,

Yes, as previously announced we plan to support both panel mount and remote mount versions of both the GTX 335R and GTX 345R in Q3 of this year for G3X and G3X Touch systems. It takes a great deal of software development and testing for both systems to offer this capability. We have both G3X and G3X Touch flight test aircraft equipped with these systems now.

While your G3X system will indeed support remote controlling a GTX 345R transponder from the PFD, note that we don't currently plan to support the ADS-B receiver provided by the GTX 345 for a G3X (GDU 37X) system. We will, of course, continue to support the use of a GDL 39/39 3D/39R dual frequency ADS-B receiver for these systems which provides a similar function.

As such, the GTX 335/335R probably makes the most sense for G3X systems (or continue to use the GTX23ES). G3X aircraft choosing to install any of these new GTX 3X5 transponders may also install the internal GPS option and use this in lieu of the GPS 20A (if desired) for 2020 ADS-B Out compliance.

For G3X Touch systems, we plan to also support the ADS-B receiver provided by the GTX 345/345R (also in Q3) for those customers that prefer to install a GTX 345/345R instead of a transponder and a GDL39R. These customers may also install a GTX 345/345R with GPS option if they prefer which will perform the same functions as a GTX23ES/GDL39R/GPS20A.

If your system also has a GTN 6XX/7XX, a single ethernet connection from the GTX 345/345R to the GTN provides the ADS-B Out position data from the GTN to the transponder, and the transponder provides ADS-B traffic and weather data back to the GTN. Since the GTN doesn't interface with a GDL39, having this new method of providing ADS-B traffic and weather to the GTN in an experimental aircraft is an added benefit of installing a GTX 345/345R.

A GTX 345/345R will also provide traffic and weather to a GNS 4XXW/5XXW.

In a G3X Touch system, a GTX 345/345R can provide hardwired ADS-B traffic and weather to up to 3 GDU 4XX displays and to one or two GTN 6XX/7XX (or GNS 4XXW/5XXW).

Thanks,
Steve

Charlie, are you using the AF4500 to display traffic and weather from the GTX345, and how has it been working? Or are you only feeding the 430W? I'm considering the same transponder swap for my AF4500-equipped panel, but when I checked in with both Garmin and AFS, they hadn't heard of anyone flying the combination, and weren't certain it would work at all for display.

Off-topic, my other option is Freeflight connected to the AFS (which is verified to work), but I haven't yet determined if the Freeflight will feed G3X Touch, should that be the direction a future panel update takes me.

No data correspondence check required as you did not change the altimter or encoder (one in the same with an efis), however you do need to have a 91.413 transponder check done.
