If Data Gateway Interface (DGI) connections are not detected by the MPLAB® Data Visualizer, try the following steps.

  1. Close all applications (including MPLAB X IDE and/or the standalone Data Visualizer).
  2. Unplug the kit or tool from the machine and plug it back in again.

  1. Unplug all kits from the Windows machine.
  2. Right-click the Start button and select Device Manager.
  3. Select the View menu and turn on Show Hidden Devices.
  4. Expand the node Microchip Tools which lists DGI-capable devices.
  5. Right-click the entry for the device you want to uninstall, go to Properties, Driver tab, and click on Uninstall.
  6. On the Confirm Device Removal dialog box, if you wish to remove the driver package in addition to uninstalling the device, select the Delete the driver software for this device option.
  7. When ready to complete the operation, select OK.
  8. After completing the procedure, plug the kit back in and start MPLAB Data Visualizer.
