How does one update the firmware on the VMX Robotics Controller?


  • VMX Circuit Board (rev. 4.0 or higher)
  • PC with USB 2.0 port running Windows 7 or greater.
  • Micro-USB Cable

Updating the Firmware

  • Download the VMX Tools for Windows latest build.
  • Unpack the contents of the file and run the setup.exe program, which will install the tools as well as all necessary device drivers for communicating over USB with the VMX-pi, as well as some additional tools. In addition, the setup program will install the latest firmware at the following location:
[Installing User Home Directory]\vmx-pi\firmware

For example, if you installed the VMX-pi Software while logged in as user name "Robot", the directory name will be C:\Users\Robot\vmx-pi\firmware.

  • Within that directory, the firmware file will be named using this pattern:

(X = Major Version Number Y = Minor Version Number Z = Revision Number)

  1. Connect a USB-micro cable from a Windows PC to the VMX circuit board. Use the micro-usb connector immediately to the left of the VMX power connector.
  2. From your Start Menu, select “Kauai Labs” and then click on the VMXFirmwareUpdater menu item, and follow the directions included in the program.
  3. Once you have downloaded the firmware, you can use the “Currently-loaded Firmware Version” tab of the VMXFirmwareUpdater to verify the version number you have just installed.
