echoUAT FAQ's

Your echoUAT WI-Fi may have failed. If you can peek inside the echoUAT through the spaces around where the power plug goes in when the echoUAT is powered on. You should not see a steady blue light. If you do then the Wi-Fi has failed.

The ADS-B system is a ground based system. You may not be in range of a ground station. You may Google ADS-B Towers to bring up a map of where these stations are located.

The most likely cause is that your echoUAT is not in sync with your transponder. The transponder transmits your squawk code on 1090 MHz, the tailBeacon transmits on 978 mhz. If the echoUAT does not “see” your transponder it may transmit a code other than your transponder code, hence "2" aircraft are see. Please adjust the transponder threshold to so that the echoUAT shows the same squawk code that is on your transponder.

Your iPad may be switching to a Wi-Fi other that the echoUAT Wi-Fi. Please be sure that any other devices, cellphones etc., have hotspots turned off and set the iPad Wi-Fi to "ask for permission" to join a network. If this does not help please contact our customer support.

The echoUAT requires a Mode C transponder in order to work. If you do have a Mode C transponder, please try adjusting the transponder threshold

To be certain that your echoUAT is not working, please contact our customer support. If the echoUAT has indeed failed, we no longer offer repair/rework service as it is a discontinued product, and you will need to find another solution or a used echoUAT as we no longer sell echoUAT's and have none in stock.

The echoUAT and your transponder must be syncronized to each other in order to send the same squawk. The echoUAT will send for zeros when it does not "see" your transponder. Please try resetting the transponder threshold with your echoUAT app.

Yes the F.U.N.K.E. can be locked as a Mode A/C transponder which will work with the echoUAT. You must program the ICAO in the transponder as "000000" It can be found on pages 16,17 and 44 in the F.U.N.K.E manual.

Yes, You can run a wire from pin 7 of the Sandia 165R to pin 4 of the echoUAT and ithe echoUAT will receive data directly.

When the echoUAT app is opened, it opens to the "Monitor" screen. Select the "configure" screen and in the upper left of the screen you will see "ECHO" inside a white box. Tap on it three time and you will then see "Basic" and "Advanced" you will find the threshold setting in Advanced.

The echoALT device is a blind encoder. It is required by the FAA unless you are hard wired to your aircraft encoder. The echoALT provides altitude information when not in an area serviced by radar.

You may order the echoALT device on our website. Go to uAvionix.com, then select "support" on the top right of the page. Scroll down to "echoUAT" There you will find instructions for ordering the device. Note that you MUST have the echoUAT serial number. If not in your logs it may be found on the side of the echoUAT that is adjacent to the power connector (just around the corner) on a 1/4" metalic sticker.

There are detailed instructions in the echoALT service bulletin which can be found on the uAvionix support page. Scroll down to the "echoUAT" then click on it and find the service bulletin on the left side of the page. There is also a six minute video on YouTube detailing the complete process in real time. Look for "uAvionix echoALT" 

echoUAT Update for your echoALT Installation (Video Transcript)

uaVionix encourages you to read the echoUAT (discontinued) installation manual and the echoALT service bulletin. This video will summarize the process for you. You may use any PC, tablet, or smartphone that is capable of downloading files.

You will not be using the echo app for this process and no changes to your configuration settings are necessary. The first step is to navigate to uavionix.com on your web browser. If you are on a smartphone, you will see a stack icon on the top right corner to open up a drop-down menu, to select the “Support” tab. If you are on a desktop or tablet, you will see the menu laid out at the top of the page, click on the “Support” tab.

Once you are in the support center, you can use the search bar to type in “echoUAT” or you navigate to “General Aviation” and then select echoUAT and then select “echoUAT Documentation” to select the “echoUAT User and Installation Manual."

Once you have opened up the manual, go ahead and turn to page 19, to section 9.4.2 titled “Connecting the echoALT Retrofit,” so that we may understand how to physically connect the ALT unit into the existing echo circuitry.

The ALT unit comes with a pre-wired harness and has three connectors on it. The connectors only fit into their designated place, which will make it difficult for any mistakes to be made. When proceeding with this process, the first thing you want to do is plug the ALT unit into the second center connector of that harness.

Then carefully remove the plug out of the echo. Next, plug one end of the harness into the echo and then, the plug that came out of the echo plug back into the harness (for a better visual demonstration, watch this video). This completes the installation of the physical installation of the echo.

Subsequently, we will now download two files. Navigate to the echoUAT service bulletin and note that there is a warning that you should not proceed with this installation unless you have the ALT physically wired in.

We will need to download 1) Protocol Software (called Device 1), and 2) Transceiver Software (called Device 2). Next, you will need to go into your network settings of the device you are using and connect to the Ping Wi-Fi. You'll want to open up a browser like Chrome or Safari and type in this IP address: 192.168.4.1. This put us directly into our echo. Click on the ADS-B version, the center one where it says update and we're going to choose a file.

Again, the protocol converter file was Device 1. That's the first one we're going to be loading. After this file loads, we're going to hit the advanced button that's underneath choose file and we're going to go to Device 2. We will then wait a moment for the device to restart.

Then, we are going to go to advanced device number 2. We're going to choose the file and Device 2 was the PING transceiver. Click “Update.” Once complete, the screen will read: Update successful, device 2 restarting. After it's restarted you may now shut down because your installation is complete.

Please look at the face of your echoUAT.There are either 2 or 3 very small holes below the "C" in echoUAT about 1/4" from the bottom edge of the echoUAT, just above and slightly to the right of the antenna coax connector. If there are 3 holes the chipset it has cannot be field updated, it must be returned to manufacturing to be updated. Please contact uAvionix support for a RMA before sending the unit in.

The echoUAT flashes red once per second as it transmits ADS-B information. The echoUAT green light will flash randomly as it receives ADS-B information.

A change in the FAA SSR programming (Secondary Surveilance Radar) has rendered the transponder monitor function ("sniffing") of the echoUAT inoperative. Without hardwiring the echoUAT with a MUX cable it will no longer work.

The echoUAT MUX cable is a discontinued product and can no longer be supplied.

There is no direct replacement for the EchoUAT that has both ADS-B in as well as out in a single unit. If your EchoUAT has lost ADS-B out but still receives ADS-B in, you can add a skyBeacon or tailBeacon for ADS-B out while retaining the EchoUAT for ADS-B in. The echoESX is the newest addition to our ADS-B line, it is a full 1090 ES transponder with ADS-B out and internal WAAS GPS, however it is ADS-B out only and requires a control head on the instrument panel such as an AV-20 or AV-30 EFIS.

Yes, the skyFYX-ext is a complete WAAS GPS unit with an integral GPS antenna all in a single unit. It only requires power and ground and its GPS output connected to pin six of the echoUAT.

No, the skyFYX and skyFYX-ext may not be shared with the AV-30-C and it needs to be noted that the AV-30-C requires a GPS input from a GPS navigator, not raw GPS data such as the skyFYX and skyFYx-ext output.
