Re: Horizon 10.1 install

They’re pretty much duplicates. The efis will flash red to alert you to an issue, pretty hard to miss, so I just hooked up the red warning light to the EIS. I also set different limits, e.g., efis flashes red the cht scale if it exceeds 420 F; EIS turns the red light on if CHT exceeds 430 F. So if t...

Re: secondary power input and auto startup/shutdown

As an old electronics guy, I would recommend not running avionics during engine start, unless you have backup power. Modern electronics are usually very tolerant of over-voltage events, but not necessarily under-voltage events.

Re: secondary power input and auto startup/shutdown

The Hx has multiple power inputs but they are all equal - no primary or secondary. So yes, they all need to be switched off to turn off the unit. OTOH if one power source fails, you don’t have to do anything to keep the second supply on. The Hx takes a couple of minutes to fully boot up. It’s import...

Re: Horizon 10.1 install

I’ll try to answer a bit. First, while most of the GRT equipment has RS232 hardware with in and out pairs, it doesn’t have to be that way. For example, I have an SL30 nav-com. It has an RS232-out port, and I use it to send nav data to my GRT Hx. The SL30 also has a RS232-in port, which I could use t...

Re: Horizon 10.1 install

Glad to see you made it onboard!
Make certain that when you wire up the Garmin gps that you include an extra shielded wire connected to a spare RS232 out port. You’ll need this to go to the TT22 for ADSB-out.

Attn: Jeff

Another GRT user asked about programming his EIS, and I referred him here. But he couldn’t figure out how to get a log-in password - and neither can I! Any advice? Specifically, he couldn’t see what to enter in response to ‘I am not a robot’.

Re: Garmin GDL-39 & Garmin 796 to HXR

I can vouch for the Skyradar D2 (USB into an Hx). Works fine. I think you can find them used for $500 or less. That includes a gps source that the Hx can read and use. Also sends out WiFi to an iPad running WingX.

Re: USB GPS

I use a Skyradar D2, with its own gps, to feed adsb-in data to my Hx via USB. The Hx does see the gps data (I labeled it gps2). So it is possible.

Re: Issues with the EchoUAT

You are correct: the rules require the same altitude source drive both the transponder and the adsb-out device.

Re: new-to-me HX installation questions

I’m sure GRT Jeff will come along and answer your questions, and tell you the age of your equipment based on their serial numbers. The Mini can interface with the Hx. But carefully decide what you want the Mini interfaced to, remembering that it only has a limited number (2 or 3, I think pairs?) of ...
