Garmin GNC215 and MiniGA
To follow up on the same question about Trig TX56 and MiniGA compatibility for Nav information, is the Garmin GNC215 compatible with the MiniGA? I see that the GNC215 has both RS232 and ARINC429 outputs.
Re: Garmin GNC215 and MiniGA
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 already have ARINC 429 on their EFIS and an unused ARINC 429 input. If you want to send frequencies from the Mini to the GNC, only RS232 can do that.
Re: Garmin GNC215 and MiniGA
I didn't know if the GVC215's RS232 used the SL30 format or the Garmin255 format. You mentioned in my Trig question that the Minis at this time didn't recognize the 255 format. Is that beta software update available if I want to use the RS232 through a Serial Port Combiner? Would the settings be the same as mentioned for the Trig?
If I'm already using an ARINC429 module to connect a GPS175 to the Mini am I correct that there is still one input available, in this case ARINC 429 2 In, A and B? Would it be necessary to parallel the ARINC 429 Out to both devices? I don't need to control frequencies from the Mini.

Re: Garmin GNC215 and MiniGA
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 RS232 data can go through the serial port combiner.
Yes, you would be able to connect the GNC ARINC output to the unused 2nd ARINC input on the GRT module. What do you mean by both devices? If you are also connecting the GNC ARINC output to something else, you would splice the wires to go to both, matching A and B connections. This is a newer interface of the GNC models (the SL30 and others didn't have ARINC 429) and some customers just wired it and said it worked, so we don't have any details on it. From what I've heard it works as well as the VOR/ILS output of an IFR GPS/VOR/ILS navigator like the GNS430 and later GTN models.

Re: Garmin GNC215 and MiniGA
By both devices I mean the GPS175 and GNC215. The GNC ARINC A&B out would just go to the GRT ARINC Module if I went with that connection. While I'm not interested in selecting frequencies from the Mini would the Mini be able to select the OBS course. Could I do that with the ARINC connection or would that just be able via the RS232?
Re: Garmin GNC215 and MiniGA
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 EFIS is in.
