    Pressure altitude and heading to GTN 650 failing

    First, one thing is not clear. Has this ever worked in this plane, or has it been like this since it was installed? Something very odd is up. Here are the labels we transmit: Here are the labels I see from your GIF: In other words, none of your labels make any sense for any device in a...

    D180-Season variation on OAT accuracy?

    When was your EDC made? It may be part of this TSB from 2008, which would cause exactly what you describe: http://www.dynonavionics.com/bulletins/support_bulletin_110107.php

    EMS "CONTACT" inputs anomally

    Are you sure tach goes red X? MAP makes sense, tach does not. Is it also true that if you have 2/3 contacts at 14+V, it's OK, but only if all 3 are above it's an issue? Knowing these will help us look at what might be different.

    DYNON HELP -BOTH ADAHRS/ EMS FAIL

    It is acceptable to use resistors, except they need to be remarkably well matched, within 0.1% of one another. This means 0.05% resistors or better, which are in the neighborhood of $3 each. The bigger issue is that 5K resistors would reduce the gain by 6X, so you'd have a lot less sensitivity...

    VP-X issues with V15.x

    Jason, We've seen the lines on the VP-X like that a few times. We're looking into it. In our experience, it doesn't do it all the time. We haven't heard of the data output to the VP-X being broken, so we're not quite sure what to do there. Did you test this in-flight, and are you able to...

    Fuel Levels Calibration

    It will be obvious when you do it, but you put the 1.4 gallons in and hit "FULL" (because it's now full). The system knows your last pour is less than 2 gallons and does the right things.

    Power dual Skyviews with dual power busses

    The power on the network wires is not aircraft power. It's power after all the voltage regulation in each screen. It's at a completely different voltage than the plane's main power, and it's protected from all the noise and spikes on the main aircraft power. Clearly the system is designed to...

    User Logs - Mark Now?

    There is not a specific marker in the SkyView data log system. Options: 1) Hook a button to an unused input on the EMS, and set it up as a contact. You don't have to display it on the screen. The state will be in the data log. 2) Use a less commonly used bug (IAS?). Change it each time you...

    ADAHRS 200 inverted

    You're likely just thinking about it wrong. It feels very strange to only move the AHRS and not the screen. When you tilt the AHRS down (diving the plane), the screen moves *UP* because that way it's showing you below the horizon. Same with roll. If you're convinced, take a picture and post it...

    Powering SkyView with battery for bench testing

    Scott, That does seem odd. You can bypass the black wires and just run ground to the case of the screen if you want to try it. An alligator clip to the heat sink pins or the cage of the fans works fine.

    Powering SkyView with battery for bench testing

    Scott, There is a yellow LED on the back of SkyView that comes on when it has external power. It's on the Ethernet jack. There's no software or anything else required to make this light turn on. Is it coming on when you hook up the battery? If not, it's almost guaranteed that you have a wiring...

    Transponder failure after updating to v15

    You must remove power from the transponder after the update and then restore power. You can't just turn off the SkyView screen.

    Yes. In setup, LOCAL SCREEN SETUP, then battery, there is a BATT INSTALLED option. Set to NO.

    EMS Screen Editor

    Just look more carefully. They are all in the INFO on the EMS screen editor.

    Checklists

    The excel tool uses functions only available on windows and we haven't been able to find the time to work on a Mac version. You'll need to edit by hand or find a windows machine.

    DYNON HELP -BOTH ADAHRS/ EMS FAIL

    Kurt, This sounds like maybe one device in the network is really broken? Generally the network is very robust with lots of redundancy, but it is possible for certain shorts to take out lots of things. I'd unplug everything except the AHRS-200 from the network and see if it's OK, then work device...

    Settings export

    The main items that are not exported are HOBBS and TACH. We didn't want people loading old settings files to keep resetting their hobbs and tach.

    Updating to v15.0.3

    This is normal. The system has a "master" screen and "slave" screens. If the master turns off, it takes a second for the slave to take over. Which one is master is kind of random because it doesn't really matter to the end user. But if you want to force your P1 screen to be master, go do a...

    SV-ARINC-429 Help

    The issue is the 430 doesn't let you set two serial channels to the same format in software. No idea why, but if one is set to Aviation, it won't let you set a second one to Aviation. Unless a newer firmware changes this...

    SV-XPNDR-261 and Garmin 430W details

    You need version 5 or newer on your 430 or it does not output the data required to be 2020 compliant. Nothing we can do about that. You can install now and wait until closer to 2020 to upgrade if you want. In this case, the GPS-250 is actually a higher quality source. The Transponder does not...
