GRT Avionics

Playing around with this more, I got the Stratux to operate using the GPIO serial port and a USB to TTL-UART cable (https://www.amazon.com/gp/product/B008AGDTA4)
I had to use a power USB hub though, and the TTL-UART cable powers the Stratux from that.

Which USB to serial adapter is that? The Mini needs real RS232 levels, not TTL. The serial rate for the standard Stratux software is 38400. Our original test software was 115200. The best place to check for ADS-B communication is the ADS-B Status page in SET MENU, Display Unit Maintenance. Valid Fr...

How does the 3 multiple power inputs perform? I assumed A is main, B is secondary if A is missing. And C is the last one if A and B are missing. Out of curiosity, I hooked up Amp meters in-between and noticed if all three powers are applied, they share the amps in-between each other. I thought they ...

That sounds funny, but I understand why. Any dongle that GRT plays nice with?

Is there any support for straight USB to USB? I don't have any free serial ports.

Can the interlink send all the necessary info the HXr would need for GPS? It doesn't need the rest of messages? Geographic Latitude and Longitude (GPGLL), DOP and active satellites (GPGSA), Satellites in View (GPGSV)? I have to free up one more 'serial port' to get everything to fit on a single HXr....

Excellent. I'm receiving the raw analog inputs from the HXr. I'll just have to copy the fuel tables to my program to convert the raw value into fuel levels. Then send the total fuel BACK to the HXr via EIS to give the 'fuel total'. I couldn't see an option in the HXr that automatically adds the left...

4a) Is there a place where we can submit a ticket for future requests to add another fuel tank? 4b) So the 'Send Analog Inputs' only sends certain functions (ILS, Dimmer, Hold/Seq) but not when we select an Analog input as an Aux (EIS compatible). How do I send Remote Analog Aux 0-16? Is that the Ca...

I'm going to interface MegaSquirt's engine Can bus to your interlink EIS. It's not Can aerospace standard (or even car standard), but I can help if that's something you'll be interested into add to your module down the road. To be able to port MegaSquirt ECU to your EIS protocol standards.

a) & 3. Doah!! It was right infront of me and didn't catch it. I have character stuffing working properly now. 1. I still have 000000000000 between EGT6 and Airspeed on the interlink packet. I'm wondering are they intentionally zero based on early design? Do the tach & fuel flow stopped bits...
