    Two Radios into top line of HDX

    I currently have a Garmin GTR 225 connected to my HDX and it works fine using the GTR 225 protocol. I also have an Avidyne IFD540 in the panel and would like to connect either to the HDX selectively, using a switch: Both radios must use the same protocol for this to work, and both will work...

    Fargo

    Press release this morning says Dynon is opening a location in Fargo, with postings for software engineers. If Fargo will advance autopilot certification, it is indeed great news, and I congratulate them and wish them well!

    Serial Port Six

    HDX. I see references in the USER_CONFIG.dfg file to it, i.e., "ser_in_dev6=SERIAL_IN_DEVICE_NONE". Is it available anywhere?

    ARINC 429 Driving TruTrak Autopilot

    I have an Avidyne IFD540 talking successfully to the HDX through an ARINC 429 Module. By adding a second ARINC 429 Module, could one use the HDX to drive a TruTrak autopilot directly? In addition to just GPS lateral steering, I would think this could provide ILS and VOR steering to the TruTrak...

    HDX Touch Intermittent

    Yesterday my HDX wouldn't recognize the Back or X buttons in the top right corner. Also, by touching the Map or Engine buttons, they would highlight, but not envoke that function. I had to close the configuration window by pushing the hard Exit button. I shut down and restarted the HDX, and...

    Create an Audio Caution for a Contact

    I am monitoring my Landing Gear Pump motor with EMS37-P11, and when the pump runs, it turns the widget BLUE on the HDX. Works fine. I'd like to also get an audio tone, chime, or other headset message when the pump is running. Is this possible? c37_p11={ valid=1 name=GRPUMP...

    Brad Thurow

    Got the email today. "leads the team that develops the Dynon product line, which spans avionics for experimental amateur-built, light sport, and type-certificated aircraft.". Hopefully Brad's 1st, 2nd, and 3rd priorities are to add aircraft to the autopilot AML - we really need some good news...

    HDX Certified - Clearing the Logs

    Anyone know how to? The experimental Installation Guide ("Clearing Data Logs") says the option is available at SETUP MENU > SYSTEM SETUP > DATA LOG SETUP > CLEAR ALL DATA, but that menu doesn't exist in the certified firmware.

    Map Zoom - CW/CCW

    Re: Improved: Map zoom/range feature can be reversed so that clockwise rotation "zooms in" to the map (decreases range) to suit user preference. Anyone know how to do this? (HDX) Thanks, JJ

    EMS - EGT Difference

    I'm currently installing and configuring an HDX with EMS system and can't find anything that'll alarm when the EGT temperatures differ. My last plane had a JPI and I set the "diff" to alarm with 200 degrees difference between any two EGTs. I found this very useful in detecting FF, spark plug...

    D10A with HDX System

    The D10A just doesn't seem to be the best match as a backup attitude indicator for the HDX system. I'm reviewing everything now as part of my pre-installation planning and it appears to lack lighting control. Since it needs to stay on at all times to be a valuable backup, when night flying...

    91.411 Checks on an HDX System

    I'm planning an STC HDX installation in my Cardinal and am curious as to how the Static/Altimeter/Encoder check is done every two years. I ask because if the technician needs access to the ADAHRS static port and/or the D10A static port, I'll plan my installation to make these more easily...

    EFIS-D10A STC Usage

    My Cessna has steam gauges, and will eventually have a Skyview system when the 177RG gets added to the AML.  When that happens, I'd like to have three independent attitude displays - the Skyview, and two D10As. While I'm waiting for the STC, I'll install an Avidyne IFD540 and would like to...

    Trying to work thru ADS-B options

    I currently have an Avidyne IFD540 and plan to display TIS-B and FIS-B on it, and as soon as my aircraft gets added to the AML, I'd like to install a Skyview system in the plane. I would want to display TIS-B and FIS-B on the Skyview screen too., as well as on a tablet or phone, preferably...

    Skyview Capabilities from 2 Nav Sources

    I've read the manuals and searched as much as I could, and still have some questions about the Skyview system and how it relates to other avionics. I plan to install the complete STC'd system (10" Skyview, D10A backup, autopilot, AOA, etc.) in my Cardinal when it becomes available and would...
