For those with a 920+, you may have encountered a 390' - 400' altitude limitation when trying to perform a structure inspection. You may have also tried to remove this limitation using the Geo Fence setting function inside the Waypoint menu, which will not work. The geo fence adjustments within the waypoint menu is only applicable when flying a waypoint mission. You may have reviewed all the available 920+ documentation in order to locate references to geo fencing to assist and learned the only reference to geo fencing in mentioned in the description of the waypoint functions.

Not mentioned in documentation is that a new 920+ ships with a manufacturer established geo fence for both altitude and distance. The altitude limitation may be set for 122 meters, which works out to 400.2613', and nothing you do in the Waypoint menu within the ST-16 to alter that limit will have any effect. Despite the 400' setting the 920+ will likely not climb higher than 390' - 392', depending on what the baro altimeter is receiving for ambient pressure. I did not make note of the "Distance" fence limit but I know from experience you can fly the 920+ beyond 1,800' and not be impacted by the Distance limit. For those that need to change Geo Fence limits, do not despair, there is a solution, which will be found in the Typhoon H GUI.

To obtain the ability to make changes to the Geo fence you will have to visit Yuneec's website and go to the product Support page for the Typhoon H. Read the "Details" notes on the Downloads page and download the GUI to your computer. Note the GUI is only for Windows operating systems. If you use Mac you will need to find a work around that will provide a Windows OS. Also note the GUI software contains code that triggers a virus alert for many anti virus programs. As I don't know anyone that has de-constructed the code to inspect it you have to make a personal decision whether you want to disable your anti virus software to complete the GUI installation process. Once the GUI is installed you can link your 920+ to the GUI using a micro USB to USB cable. This may require considerable effort.

You should be aware the 920+ and GUI appear to be very sensitive to minor differences in USB cables, and the USB cable that was provided as part of your 920+ kit to be used for charging the ST-16 may not work when trying to link with the GUI. Be prepared to try several USB cables to locate one that will permit connection. Unfortunately, you won't know if your USB cable works until your 920+ makes connection with the GUI, where a few more obstacles that need to be overcome may present themselves.

An initial connection process to make the connection works as follows; You will not need the ST-16 for this process.

Remember to remove the propellers from the 920+ before performing any bench activities that require the aircraft to be powered up.
Accidentally depressing the arming button on the ST-16, or a "glitch" within the 920+, could quickly be fatal or cause extremely severe injury to yourself or others. Any activity performed with the 920+ powered up is at your own risk.

Changing the 920+ Geo Fence Limits
  • Start the GUI on your computer
  • Note the message at the bottom of the page referencing connection method and the serial port for use
  • Go to the Sensor Information page
  • Install at least one battery in the 920+
  • Connect the USB cable to the micro USB port at the front of the 920+ next to the CGO-4's cable plug at the bottom of the 920+
  • Connect the other end of the USB cable to your computer, power up the 920+
  • If connection between the GUI and 920+ is made, skip the following instructions and go to the later section titled "After Successfully Connecting 920+ to the GUI".
  • Go to Device Manager in your computer's Control panel to see if "Ports" has been populated in the listings
  • If Ports is showing, click on that to establish if something titled STtechnologies (or similar) now occupies one of the ports. If it does not your computer is not recognizing the GUI connection. Try a different USB cable
  • Wait for a few moments to establish if sensor information becomes visible in the GUI. If all you see is several small "wheels" turning at the top of the page that never stop the GUI is not connecting.
Trouble Shooting GUI Connectivity
  • At the top of the GUI there are three Drop Down Headings, click "Edit", mouse over "Connect Ways" to determine if USB or Serial Port is selected. Although you have connected via USB the GUI may require that Serial Port be selected to complete the connection.
  • After changing the connection method, return to the drop down selections and click "File", then click "Connect" and wait a few moments to observe the results. If that fails...
  • Return to the "File" drop down, click File, then click "Settings". This will open up a new "USB-Serial Port window that allows to see port and baud rate information. Use this information to make alterations in your Device Manager>Port Settings to match the information in the GUI USB-Serial Port window. After altering your Port Settings...
  • Click the File Drop Down, then click Connect
The process above may have to be repeated several times before you obtain a USB cable that will make a connection. Sorry, but it's pure trial and error, and you may also have to try several variations of the methods mentioned to make a connection, but the 920+ WILL connect with the GUI once you've established the process sequence necessary to make that connection. Understand the GUI will identify your 920+ as a Typhoon H. This is not an error and is of no consequence. You cannot change it. An item missing from this version of the GUI is the ability to change from Metric measure to Imperial measure. You're stuck with metric in the GUI but you can change from Metric to Imperial through the ST-16 when the flight system is powered up to use Imperial measure while you are flying. Use a Metric to Imperial converter that can be found online if you need to make conversions before changing the Geo Fence settings.

After Successfully Connecting 920+ to the GUI

Once you have a live connection between the GUI and 920+ you will need to go to the "Settings" page of the GUI to make changes to Geo Fence limits. Any change you make to the fence settings must be followed up by clicking "Update" before they will be applied. The maximum allowable limits are 1000m for Altitude and 2500m for Distance. Once you have completed your changes return to the "File" drop down and click "Disconnect". After that turn off the 920+ and shut down the GUI. A picture of that page is attached for reference.

If you have one of the original 920's that has not been converted to the 920+ I have absolutely no idea if your system can connect to the Typhoon H GUI. In a conversation with a Yuneec Tech Rep it was mentioned that he has always used the H GUI to communicate with the aircraft system but there was no specific mention of the original 920.

Have to check that on H920.
Originally, I had thought the older 920 would lack NFZ limitations. Was surprised to read it did have same limits.

Thanks for your help with this. I followed what you said and it worked. I can fly high now.
