Microsoft Windows 7 Manual Driver Installation

This section outlines the manual driver installation process. If you are using Windows 7 or if the Windows device manager shows 2 USB Serial Devices under as other devices when the EVM is plugged in instead of COM ports as shown in Figure 5-1, use the following steps. If two USB Serial Device devices show up as COM ports automatically (as is the case with Windows 10), then this section can be skipped.
