Note: Installing and using the USB drivers for the TDC Ultra is only supported for the Windows 7, 8, 8.1, 10 & 11 operating systems.

IMPORTANT: Two drivers will be installed, one right after the other. When you first connect a TDC Ultra to your computer, the USB drivers are automatically available through Windows Update. This is the recommended method for installing the drivers and is described below.

If you have trouble installing the drivers automatically, they can be installed manually by downloading them from the link below. This file contains everything needed to install the USB drivers for the TDC Ultra.

Step 8

To install this second driver, follow the same steps as the first.

Once the second driver is installed, you may see a message like the one below, prompting you to restart your computer.

Step 9

The process of installing the USB drivers has created a virtual comm (serial) port on your computer and assigned this port a number. You will need to select this comm port number in PETRAPro when you go to download your Ultra. PETRAPro makes this easier to do by only listing the comm ports that are available in the download screen. If you want to check to see what port number the virtual comm port has been assigned, you can do so through the computer’s Device Manager list, as shown here.
