How to Update the AV-30-C Software (YouTube Video Transcript)
In the video demonstration: "How to Update AV-30-C Software Video," we demonstrate how to update the AV-30 unit. The items you're going to need are: 1) AV-30 device, 2) 15-pin D-sub connector, and a, 3) 9-pin D-sub connector. This video will demonstrate what wires you will be hooking up and to which location.
First, you will need the Sabarent cable and a Windows operating laptop. Next, you will want to address the steps below in the following order:
- The 15-pin connector will pin, pin 1 with power. Then pin 9 with ground and 8 with 15. Then, you will be plugging in the 15-pin.
- Next, Pin 8 is going to go to pin 3, pin 15 is going to go to pin 2.
- Then, on the ground wire, you will parallel that wire with one wire is going to the power supply and the other to pin 5 of the 9-pin dsub.
- Lastly, of course, make sure the power and ground do to touch each other because that could cause problems.
Now, you have the ground wire going to both the 9 ping dsub and to the power supply. You are now going to take the Sabarent cable out of the packaging. Take note that one side of this cable is a male 9-pin. We're going to take this one, plug it straight into the USB port on the AV-30 device, which allows us to power on the AV-30. Now, it is time to turn on the power supply. In this video demonstration, we have it on 12 volts.
When the AV-30 is powered on, you are going to see the software version that you have running on your unit load onto the screen—the demonstration video shows that this AV-30 device has the 2.3.9 software version. Once the unit is powered on and going, we will turn on Windows laptop and navigate to uavionix.com. Once on the website, navigate to the “support” tab, navigate to the appropriate product category (General Aviation), and then select "AV-30." You will then select the service bulletin with the most recent software update [3.2.1 is the most updated]. In the service bulletin article, you will want to select and download the AV update tool and the firmware. Once it is downloaded, you cannot open it and you will not be opening it.
Moving onto the update tool, you will click on that. You will select “more information” and then select “run it anyway.” Next, you will select COM port 8 because that's what it selected. We're going to press “connect.” Then, the AV-30-unit screen will go black. Next, we will select “open file.” This will then prompt to bring up a downloads file and then you will select the file that you just downloaded and select “write firmware.” After this action, you will begin to see that it's going to start programming and running it. The AV-30 screen will remain black, and it will remain that way until the update has been completed.
Once it has finalized and updated, the unit will come back on. The screen will go from black back to the uAvionix logo and load. It will then show the newest software version, demonstrating that the software download and update process has been successful. For a visual representation of this process, select and watch the video listed above this article.
A pitot zero calibration will be required in order to resolve this issue. Please refer to the installation manual. To shut off the AV-30 until the pitot zero is completed, press and hold the left and right buttons until it shuts off. See Video.
Tech Tip Tuesday: How to Complete Pitot Zero (Video Transcript)
In addition to this demonstrational video, please refer to our Support Article: How To Complete A Pitot Zero On the AV-30.
In this video, we demonstrate how to complete PITOT ZERO. You may need to complete PITOT ZERO if you just completed a software update, or you are indicating airspeed while on the ground or in the hanger, and that's going to be indicated here [left-hand side of the AV-30 device, see photo below):
In order to begin this process, you will need to turn off the unit and place the unit in “install mode.” So, first, you are going to power off the device and wait until the screen goes black. Once it has, you will press the center button (PUSH-SET) and apply pressure until you see the uAvionix logo appear—which will then be your sign to release the button.
- Once the AV-30 device has fully powered on and loaded, you will follow the instructions below:
- You will press the left button (left of PUSH-SET button) 1X to select “Menu”
- You will then come to a sub-menu, and you will press the left button 2X and you will see “INSTALL” pop up on the screen.
- Using the center “PUSH-SET” button, we are going turn the knob to the right until we see it show “PITOT ZERO PRESS TO ZERO”.
- The screen states to “Press” in order to “Zero,” so we are press the center button 1X to make that selection.
Once you have pressed the center button, the font will go from white to purple and your screen will read: “Uncover Pitot. Aircraft must be stationary and in still air.” At this point, you will want to remove your PITOT cover if you have one, or anything that may be covering it. Then, you are going to press the right button (HLD BRT) in order to select “ZERO.” The device will then proceed to take a measurement, to see if there’s a difference between PITOT and static.
The screen will then read: “Measurement complete. P-S difference __.” In this demonstration video, we have a difference of 1.1. Once the measurement is taken, it should clear any indicated airspeed that you have there, and it will also be ready for the software update also. At this point, press the left button to select “DONE” and go back to the “Homepage” of the device. But now that you have completed all of these steps, you have successfully completed “Pitot Zero.”
Please make sure that the display shows DG HEADING and not GPS TRK, you will select the center knob until the display shows DG ADJUST, use the center knob to scroll either left or right to set proper DG heading. Watch this video on the difference of GPS Track and DG HDG.
Tech Tip Tuesday: Difference Between DG, HDG, and GPS TRK (Video Transcript)
In this video, there is a demonstration of how to identify the difference between the DG heading and the GPS track on the AV-30 and what you need to know about these differences. In this video demonstration you will see a top unit and a bottom unit. The top unit displays “NO DATA.” The reason for that is not because it doesn't have DG heading, but because the GPS has been selected and it's either not turned on, or it is perhaps not installed.
With that, we are going to press the left button on the unit (top unit in the video). This will then bring up the menu, and it will read: “EDIT FIELDS SEL FIELD” on the bottom of the screen. Press the center button (PUSH-SET) in order to select that option.
Following, you will turn the center knob until you see “DG HDG” and then press the center knob 1X to make selection. This will then take you back to the sub-menu of “EDIT FIELDS” and just press the left button 1X to select “DONE.” In the video you will note that there is now a DG HDG.
In this demonstration video, we have AV-30 device connected to the AV-Mag and it's displaying the magnetometer heading. If you don't have a magnetometer connected, then it would display whatever's there. In order to correct it, you should press the center (PUSH-SET) button until it brings up a sub-menu. You will continue to press the center button, until you see “DG ADJ” and you can turn the center knob to adjust the number, because the AV mag connected, you would be able to change the heading.
After adjusting the DG Heading, press the center knob 1X to complete. Please note that this will eventually reset after the power cycle. Moreover, in the second half of this video, you will see a demonstration of the bottom unit. The heading is actually the DG heading, GPS track, no data. And that's because we don't have our GPS turned on. You'll also see waypoint is dashed out.
In order to change that, you are going to press the left button 1X, and then press the center button (PUSH-SET) 1X, and begin turning the knob to the right to select “HDG ROSE.” And with HDG ROSE, you're going to now have the correct heading being displayed there.
You'll know that you're looking at GPS track if all it will do is display north. The unit defaults to north if looking at GPS and it doesn't have a GPS input. And that's how you see the difference between the two units.
In this demonstration video, we show you how to change the heading bug. You press the center (PUSH-SET) button until you see “DG ADJ,” and you use the center knob to select (change number). If you're unable to adjust the unit, that means you're most likely displaying the GPS ROSE. You will only see the heading change on the left-hand side, not at the top of the screen. And that's how you see the difference between DG heading and GPS track.
Tech Tip Tuesday: AV-Mag Calibration (Video Transcript)
Confirm that Serial 4 has been set to AV-Mag and that the configuration has been completed correctly. Watch the video on the Calibration of the AV-Mag. Additionally, please refer to our Support Article: How To Calibrate The AV-Mag From The AV-30.
In this video, we will demonstrate how to calibrate the AV-Mag. You will see a flashing “MAG CAL” flag on the right-hand side of the device (noted in video). The first thing we need to do, is to into the install menu, so press the left button 3X. Then using the center knob (PUSH-SET), you will rotate to the MAG-CAL.
To begin to calibrate, you will need to press the center button 1X, and then press the right button (HLD BRT) 1X, that reads: CALB on the lower right-hand screen of the device.
After completing those steps, you will wait several seconds until the unit tells you that we can line up on north. Once it does, you will move on and click press the right button 1X to select “NEXT” and wait for it to calibrate. Then, the unit is going to tell us to turn to three zero. As long as you know north, you're going to have a countdown as it takes you down to zero, and then you'll be able to click the next button then—eventually take you to the next setting.
In the video, it is demonstrated that there is a 12-point calibration, and you are eventually able to press the right button 1X to select “NEXT.” The video then shows that the next setting is going to be zero six zero, which will require for you to wait for that to calibrate. When you are doing more than one indicator, you can do them at the same time.
Following, you will press the right button 1X to select “NEXT,” and now it's going to direct you to go to the next setting of zero nine zero. While you are completing this progress, it is also recommended that you have your normal amount of lights on, in order to highlight any discrepancies that may exist. You would be able to see this while you're doing the calibration.
Next, you will move onto one two zero degrees. You will be able to note the countdown all the way to zero, so you will not have to worry about getting on the compass rose. This video demonstration shows that we could just refer to the north and then use the AV-30 for the rest of the headings.
Important things to remember while you're doing the AV-MAG calibration:
- If for some reason you get a “NO MAG” flag, then you need to check and make sure that your connections are correct and that there's nothing prohibiting it from being connected. There is a brown wire, a red wire, and a black wire, and if any of those wires are not connected properly, you will not be able to get the MAG-CAL.
- If you have a “NO MAG” flag, you will not be able to complete the MAG calibration.
Following the last step we just completed, we will move onto making a heading to two one zero. If for some reason after the MAG calibration, you observe some deviations in the DG heading or you see it jumping around, pay close attention to what has been turned on or off, or investigate if anything may be causing interference with the magnetometer.
The hope is that during the installation phase, everything was turned on and it was ensured that nothing was present that could potentially interfere with it.
During the installation, observe the DG heading, as it should be a steady turn, and not moving around. If you see the heading moving around, it should not jump back and forth several degrees. If you note something like this during the install process, you will need to find a different location or figure out what may be causing the issue. For example, strobe lights can cause problems—the grounding of the strobe lights, specifically.
Next, in this MAG CAL process, we move onto two seven zero. At this point, we are almost done, with two more headings to go. Something to note is that if you do go past a heading, you can always go back to it. You will need to turn—if you're going right and you go past it; you can just go left and go back to that heading. With that, keep in mind that you're going to want to make sure you have a large space to maneuver around. Most airports have either a grassy area or even a paved area that you should be able to go and maneuver around. And as mentioned before, all you need to know is north.
Finally, we move onto our last heading. The last one may take a longer time than the previous ones. Once you are done, you will want to go through and verify all headings and adjust if necessary. If you are off just a little, and you want to make sure everything is exactly right, you can still adjust DG heading. You will want to access the PUSH-SET menu, by pressing the center button, and it will be the last adjustment. You are able to do this if you want to get that one degree closer to the most accurate reading. Keep in mind that the power cycle will reset adjustments.
Tech Tip Tuesday: How to Unlock Advanced AP on the AV-30 (Video Transcript)
Please refer to the Installation Manual, as well as our Reference Video. Additionally, please refer to our Support Article: How to Unlock Advanced AP on the AV-30.
In this video, we demonstrate how to unlock the code for the autopilot GPSS. The first thing you want to do is ensure that everything is off. Next, you will press and hold the center button of the unit that you wish to unlock, until you see the uAvionix logo appear. Once you see the uAvionix logo appear, you can release the center button.
Following, you will want to be sure that you are selecting one of the pages. At the bottom of the unit, you will see “MENU” on the bottom left-hand side, and on the right, it will show which page you are on (in this video, it is 1:3). You will go into the MENU, by pressing the left button 3X until you see the screen at the bottom read “INSTAL ROT TO SEL” [ROT TO SEL= rotate to select].
Then, by using the center knob, you will rotate to the right until you see “ADVANCED AP.” When you arrive to this function, it will either say “LOCKED” or “UNLOCKED.” In this video demonstration, it states it is “LOCKED.”
Next, you click the center button and one thing to make note of is a QR code will pop up when it is done aligning. You will then take your smartphone and scan the QR code with your camera. It will give you a web address that you will need to click on, and it will take you to the place where you will need to purchase your unlock code. The “activation code” will be provided to you once you have checked out.
Once you have received the activation code, you will insert it into the device, using the knob to place the accurate letters and numbers. As you rotate to select the correct letter or number, be sure to press the center knob 1X to make the selection, so that you can move onto the next. Once you have pressed the final number, your screen will read: ADVANCED AP ENABLED.
