The GNC255 didn't have ARINC input and I haven't seen the 215 install manual. If it doesn't have ARINC input, the only way to control OBS from the EFIS is through RS232. If it has ARINC input, it may work, but our ARINC output sends the same course select to everything based on what NAV MODE the ...

A beta update with the GTR/GNC protocols is also available for the Mini but just hasn't been posted to the web site yet.

We usually use the RS232 interfaces when we can although the ARINC interface is good if you don't care about frequency transfer or anything besides VOR and ILS display. The GNC ...

Yes, the GNC215 has a similar RS232 interface to the SL30 and it is compatible with the SL30 format for frequency input. Our beta software update supports the newer Garmin GNC RS232 protocol. I have heard of customers using the ARINC 429 interface of GNC2XX models for the VOR/ILS display if they ...

We had some customers who wanted to manually limit what alarms are enabled during special flight operations. When this button is set to F/O-PRS, then only Oil Pressure and Fuel Pressure alarms are enabled and all other alarms are disabled.

I got a model 122020 to work on a Horizon 10.1 after finding updated driver code from earlier this year. I just need to make one more update. I should be able to make updates for the 2nd HXr processor and 3rd HX processor/OS from around 2017+. It will take more work for the earlier processors so not ...

Yes, ours depends on the static pressure. The pitot input pressure is measured relative to static, and the AOA input pressure is measured relative to static, and then we compare the relative pitot and AOA pressures.

That's a video signal issue and we can still fix that on the SX models. It has to do with the video cable and connection. You can send it to GRT with a copy of the Service Request Form inside the box to get it fixed. Get the form from our Support page:

If you mean the PFD split pages that have map, there are only two versions of the map available: arc view and HSI. The HSI is 360 but has very little map data.

The full width map pages can have a 360 map or 360 HSI, but no PFD.

You can't view it in the SET MENU. The other displays will detect that a remote channel is available as an option for a bar graph or data box. You have to go to a bar graph or data box setting on the other displays and set it to the remote channel. The remote channel number is just a unique number ...

We had other modules a long time ago but only the Safe-Fly now.

The Stratux and other standard receivers send some limited GPS data as part of the traffic interface. The EFIS can use this if you turn on SET MENU, Display Unit Maintenance, "Advanced ADS-B Receiver Settings", and then configure SET ...
