NavX-MXP Board User Interface

This is my teams first year trying to use the NavX board on our robot. We bought the board and ran the setup to get all of the different interfaces, but when trying to load the UI to see the Rotation, and all that other stuff a black screen shows up saying no com’s in red. I have contacted Kuwai Labs and they said run the setup.exe file as a administrator to download the drivers for the board. When I did this still the same problem. Any help would be appreciated, thanks in advance!

Try unblocking the zip file per

Then connect the navx micro usb port before you open up any navx programs and watch for the driver loading.

It sounds like you are not connecting the navX to your computer via a serial port. If you have, then my next guess is that you are telling the navX to use a different port than the one your computer has. Look in the list of ports in the device manager (in the control panel) for the correct COM port to tell the navX.

I am unable to even get to the Com tab to change. I have tried running as admin, and i have made sure Windows 10 wasn’t trying to protect me from harmful things. Also, i never see the driver loading. When i go into Manage Devices it always says it needs drivers.

I have the same issue. I have Java JDK 11 and JRE 8 installed and have reinstalled & ran with admin privileges.

Have you tried a second pc / cable? Are you connecting the navx before you open navxui? We found we had to do that before the driver would load

Yes we have tried another computer and it works. But we neef a differnet one because that one won’t be there as it is a mentors. And we try load the UI after it gets connected but still the same issues. We are just trying to figure out why it is being so choppy for us, where it works on one but not the other using the same install steps and everything.

Alright, for this issue i contacted Kuiai Labs for help. It has something to do with the Serial Ports that Microsoft uses for Windows 10. So, if you are running into this error just tell me, and i will post everything that is needed to get the board to work correctly.

OK, had the same issue with the navx-micro (uses the same PC software) and the folks at Kauai Labs were very helpful. After a couple of messages back and forth, it turned out I needed a new USB serial driver on my (Windows 10) PC; the version I received from Kauai Labs was installer version 1.5.0 (the Windows 8 installer, which runs on Windows 10) – it was called “vpcinstaller”, I believe. So if you’re connecting the navx via USB, this could be the same problem.

Once I installed the new USB serial driver, the navXUI software worked fine on the PC.

If you need to reference my issue with navx support, it was support ticket #000075.

Hope this helps!

That was the same as mine. They were also very nice and helped out. When i talked to them they said that they were working on updating the download package so hopefully soon it will comeout so this isn’t a future issue

Any update on this? If anyone still has the correct installer file and could send it that would be great.

please post everything… I can’t find the Windows 10 native inbox driver which is referred to as being required on Windows 10 (instead of the virtual comm port driver).

Here’s a link to the latest USB Serial driver installers.

This is installer version 1.5.0, newer than the one currently installed w/the navX-MXP setup.

Choose the 32 vs 64 bit version to match the 32/64-bitness of your Windows OS. Then run the Windows 8 installer (this should be run as administrator on your computer) This will install updated .inf files so that the vendor and product id of the navX sensor property indicates that the Windows 10 usbser.sys driver (provided by Microsoft) should be used.
