CONNEXT...
If I have a GTN625 with no Com/Nav, is a serial connection for CONNEXT needed to the PFD or MFD? If needed, which is best?

Different drawings show different things too.

Should the GSU25 backup serial port go to the PFD, or the GTX45R? Seems the GTX is a better choice since that keeps ADSB going even on a CAN bus or PFD failure? The GTX would be getting GPS via ethernet in that mode still.

Should a serial GTN->GTX link be provided for backup even when an ethernet is cabled in?

Hello JDA_BTR,

Yes, the Connext interface shown between PFD1 and the GTN on page 26-26 of the Rev. AB G3X Installation Manual is needed for the GTN 625 if you want to be able to push flight plans from the PFD1 display or from an external portable device Bluetooth connected to PFD1 to the GTN.

This is purely an optional feature and not needed to use the GTN and fly IFR if you don't want to install this RS-232 connection.

Thanks,
Steve

Hello JDA_BTR,

The GSU 25 ADAHRS to GTX 45R transponder interface is a single RS-232 interface and is shown on page 26-22 of the Rev. AB installation manual. This interface has absolutely nothing to do with a GSU 25 backup data path.

The GSU 25 RS-232 backup data path to a display (PFD1 recommended) is shown on page 26-9. There is no such thing as a GSU 25 backup data path to a GTX.

The Ethernet interface between the GTN and GTX 45R shown on page 26-22 is a bi-directional link that both provides ADS-B+ data to the GTX 45R enabling it to provide ADS-B Out and provides ADS-B traffic/weather data from the GTX 45R to the GTN.

We don't recommend both the Ethernet interface and an RS-232 interface to get GPS data from the GTN to the GTX and haven't tested that, but it might work.

Just follow those two wiring diagrams on those two pages and you can't go wrong.

Thanks,
Steve

Just connect a single serial port connection from the GNC 255 to your PFD as shown on page 26-15 of the Rev. AB G3X Installation Manual.

We recommend you connect the MapMX serial interface from the much higher capability GTN 625 to the G5 serial port input like shown on page 62 of the Rev. C G5 Installation manual. Note that this same GTN serial output is also connected to the PFD.

With this installation, you could turn off both the GDU 460/470 displays and still fly an autopilot coupled LPV approach with the GTN 625 and G5, and of course fly an autopilot coupled flight plan entered on the GTN anywhere you like.

Thanks,
Steve
Dear Steve. I need to connect a GNC 255 to G3X GDU 460, I cannot find page 26-15 of the Manual. Is there any installation guide or manual for this interconnection ? Thanks !

Maximo,

See page 27-25 of the current Rev. AP G3X Touch Installation Manual.
