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).

AltonD 05-27-2016 07:44 PM

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.

No. I don't think the Garmin GTX 345 can interface that way with the AFS 4500. Maybe Rob Hickman or his staff at AFS could answer that question.

However, I understand the GTX 330 offers a Traffic Information Services (TIS) interface when connected to the the AFS 4500. It requires connection between GTX 330 serial port #1 to the AFS 4500 EFIS serial port #2.

I digress.

My GTX 345 is wired to my Garmin GNS 430 W and I should see traffic and WX but honestly when I flew yesterday I didn't think to look for traffic on the 430 screen.

The Bluetooth connection between my GTX 345 and Apple Ipad Mini running Foreflight works well. It's really surprising to look at Foreflight and see how much air traffic is out there around you that I can't actually see when scanning outside.

I have a Garmin Aera 660 coming. Looking forward to testing that out as well.

Freeflight was an option I consider as well. I choose Garmin because I too I'm seriously considering an eventual change from the AFS 4500 to the Garmin G3X Touch. The decision to get the Garmin GTX 345 now was based on that and a couple of other things.

1. Foreflight
2. I could get all the benefits of ADSB in/out and still be able to interface with a G3X down the road (3rd quarter).
3. All-in-one.

I did not want a remote transponder. I like my transponder right there in the panel where I can readily push the buttons. I'm thankful Garmin offered this solution. I swapped a GTX 327 for a GTX 345. They look almost exactly the same except the screen on the GTX 345 is nicer in my opinion.

I really like that I only need one transponder antenna with the GTX 345. That one antenna transmits and receives ADSB. Pretty cool.

Had I gone for the GTX 335 and the GDL 39R solution I would have needed a receiver antenna for the GDL 39R.

GTX 345 Bluetooth Pairing
 
Hey Garmin Experts,
Installing the GTX 345. It has no Bluetooth function under the System(SYS) Menu group even though it is enabled in the installation configuration.

Also, the GTN will not allow interface configuration of RS-232 GTX w/TIS+ #1.

Where did I go wrong?

Hello Kent,

For a GTX 345 not being controlled by a GTN, the "Bluetooth ON" selection on the system page is the 4th page down just past "Messages".

For a GTX 345 controlled by a GTN (V6.11 or newer GTN software), the Connext Setup page on the GTN supports the addition and management of Bluetooth paired devices for the GTX 345. Page 15-48 of the Rev. K GTN 6XX Pilot Guide provides an explanation of this feature.

The GTX 345 uses RS-232 "REMOTE FMT 1" for control via the GTN. The GTX 335 supports TIS-A traffic, but the GTX 345 does not since it supports ADS-B traffic.

An Ethernet (HSDB) connection between the GTN and GTX 345 allows the GTN to both send ADS-B+ GPS position data to the GTX 345 and receive ADS-B traffic and weather.

Please contact us directly if you have additional questions.

Thanks,
Steve

Trevor778 07-18-2016 11:00 PM

Once you have the gtn and gtx talking correctly you will pair the bluetooth of the gtx through the connext page in the gtn. Seems a little backwards i know, and you don't want to know how long it took me to figure that little one out since it's not spelled out anywhere in the gtx manual.

Is there a minimum hardware/software revision needed for the GNS430W to work with a GTX345? If so, what is involved in getting it updated?

Larry,

Yes software. I removed my GNS 430W and brought it to a Garmin Dealer. I explained I was installing the Garmin GTX345 Transponder and needed the most recent software update so my 430 would talk to my 345. They had done a few GTX345 installs and in addition to the software update (I think version 5.30V) they also configured my 430 to interface with my 345.

GTX 345 software updates
 
I purchased & installed the GTX 345 in Nov 2016. At the time I was told that we home builders could not perform any software updates to the 345, only dealers could do it. Has that changed?

I could not find on the Garmin website what the current software version is. In my 345 I have v2.03 XPDR, 2.02 ADSB & 6.0 GPS. I do not no if these have been updated or if still current.

Steve or anyone, is my unit current? If not, do you know if Garmin will be at the AOPA fly-in at the end of April in Camarillo, CA & be performing updates if I bring the unit to them?

If one gets the GTX 345 with GPS - can that GPS be used as a source for other devices - specifically I was wanting to now if it can be used by my 406 ELT as a GPS source?

Hello Corefile,

Your ELT would probably need NMEA or Aviation formats, and neither of those are available from the GTX 345 w/ GPS.

Steve, what about a gps source for a GTR 200 or a D180?

Streamline the D180 RV-12. Replace the SL40, GTX327, Intercom and 496 with a 345 for 2020 and GPS, a GTR 200 for com and intercom, finally an iPad with FF for navigation, traffic and weather?

470 with sl70
 
I just had a gdu 460 installed and am pairing with my old sl70 for now. I was under the impression that I didn't require the old alt encoder however I can't seem to get alt to function. Would love to know if I'm either doing something incorrectly or if the encoder is actually required.

Thanks.

Hello CT,

Just providing GPS position to a GTR 200 has zero value.

The VHF Out format provided by many Garmin portables (and G3X/G3X Touch systems) provides frequencies and identifiers for nearby and flight plan airports and supports selecting and sending frequencies to the GTR 200 from the waypoint page.

More information in this thread.

While drawing up schematics for a GTX-345 install in my RV-6A, I came across this question:

I am using the Garmin GTX 3XX AML STC Installation Manual, Revision 8. Looking at Figure B-11 on page 17 of Appendix B, there is a NOTE 5. This note states that pin 21 and pin 42 are NOT USED.

These two pins are the Aircraft Power pins for the GTX-345. I can only assume this NOT USED note is a typographical error and these pins really are used (as indicated by other diagrams in this section).

Now for the question: are there other pins on the P3251 connector that are not to be used that Note 5 was intended?

MY specific unit is a GTX-345 with GPS with GAE optional encoder.

Hello Noel,

Sorry for the confusion. "Not Used" next to Note 5 on the notes page is meant to indicate that this note is not used for this drawing.

There is a note 5 relating to the two power pins on the GTX 330 installation drawing that doesn't apply to the GTX 345, so this note was marked as "Not Used".

Thanks,
Steve

GSU25 with SL70
 
Hi, on a new install of a GDU460 with GSU25 and (old) SL70 we can't seem to get altitude information to the SL70. Will this G3X provide this information or are we trying to do the impossible and should reinstall the previous altitude encoder?

G3X Expert: Need some "programming" advice
 
Getting ready to self install the GTX 335 into my RV7A. Steinair is sending me a conversion harness to speed up my wiring. I've already installed the adsb antenna. I currently have a GTX 330 (non-ES) which worked well but is not ads-b compliant. The cost of upgrading both my 430s (non-WAAS) and my 330 was just too great so I decided to swap out the 330 for the 335. My dual EFIS' are the old GRT Horizon WS model with a 429 link.

My questions are related to programming. Could you send me (PM) the recommended settings for:
1. Section 6.5 (Interfaces)
2. Section 6.6 (Unit Settings)
3. Section 6.7 (Display Settings)
4. Section 6.8 (Sensors)
5. Section 6.9 (ADSB)

Also how do you enter "letters" for the model S hex code and tail number?

Love the sales price for the 335 kit! Just wish the 345 had a similar deal.

Hello Cyrus,

The older transponders supported by G3X/G3X Touch are shown on page 26-21 of the Rev. AB G3X Installation Manual. You will notice that all of those transponders support the "Remote" or "Remote + TIS" RS-232 format.

I dug up an SL70 manual, and it doesn't seem to support the required protocol.

The G5 flight instrument supports a more generic altitude encoder output, so if you have a G5, you could try using this unit to supply pressure altitude data to your SL70, but we haven't tested this.

Thanks,
Steve

Can the 796 be connected via the bare wire mount to a 900X/GDL-88 combo or do I need the Flightstream 210? I'm still stuck waiting for my software upgrade on the 900X but I'd like to set an appointment for the GDL-88 install.

Hello Scott,

Are you using V5.30 G3X Touch software?

Do you have one of the 4 serial ports on the GTX 45R connected to an RS-232 port on each of your display(s) configured for "Connext 57600 baud"?

You will also want to configure the ADS-B Receive Capability fields of the transponder configuration to show that UAT and 1090ES reception are enabled to make sure you receive TIS-B traffic.

With this software/configuration/wiring the ADS-B In services should automatically become available.

Thanks,
Steve

Hello Marc,

The GDL88 doesn't support the newer "Connext 57600 baud" serial protocol for ADS-B traffic and weather provided by the GTX 345/345R/45R, so it cannot be connected to the Aera 660/795/796 over a hardwired connection.

A FlightStream 210 connected to a GDL88 should work, but only as a wireless connection to the 796.

Thanks,
Steve

Yes, I have 5.3
RS232 IN4 on the GDU460 comes from serial 3 on the GTX 45 and is now set to connext 5700.
On the transponder port 3 has AFS-B. Connext 1, connext2 and GNS options.
Port 2 goes the the GPS20 and has the same options.

Thanks.

Hello Scott,

Page 26-22 of the Rev. AB G3X Installation manual explains how to wire and configure a G3X Touch system for a GTX 45R transponder.

It explains to configure the GDU serial port for "Connext 57600 baud" and configure the corresponding GTX 45R serial port for "CONNEXT FMT 1".

The following page (26-23) in this installation manual shows how to wire and configure a GPS 20A and specifies you should set the GTX 45R port connected to the GPS 20A to "ADS-B+".

Thanks,
Steve

Garmin GTX 345 Install Update
 
I bought and installed my Garmin GTX 345 last year before Oshkosh. I use my Garmin 430W with software updates as the GPS position source. I use the altitude encoder from my AFS 4500. I really like that I only need one antenna to both transmit (ADSB out) and receive (ADSB In). Many of the other systems I looked at required two antennas.

The 345 is connected to a Garmin Aera 660 via the Barewire Cable. I use the bluetooth connection with my Ipad mini using Foreflight as my backup. It's really great being able to look ahead at WX.

I'm surprised by how much traffic is out there that you never see. Its really nice to get audio alerts as well.

This combination has worked flawlessly for over a year. I remain very impressed with these products. I have not required service but when I had questions I received quick and complete responses. I am very satisfied.

Regrets:

If I waited a few months I would have qualified for the FAA $500.00 rebate.

I see there's a software update available for the GTX 345. Can I do that or do I have to bring it to a service center?

Hello Charlie,

Thank you for your report. I am with you. Having ADS-B traffic is awesome. On most days I fly, it is more important than weather.

If you are coming to Oshkosh, we can update your transponder software there, otherwise you would need to visit your dealer.
