USB Tethering Configuration


This document will cover the step by step instructions for configuring USB Tethering on the EnSURE™ Touch. It will also cover the requirements and troubleshooting steps.  


EnSURE Touch needs an internet connection to communicate with SureTrend Cloud. Most customers will use the Wi-Fi features of EnSURE Touch. In some cases, Wi-Fi is not available or acceptable. EnSURE Touch can be connected to a Windows 10 computer using the USB cable that comes with EnSURE Touch and share the internet connection of the Windows 10 computer.


  1. Windows 10 computer with an internet connection and an EnSURE Touch.
  2. Permissions to install Windows 10 RNDIS6 driver.
  3. Permissions to configure Windows Internet Connection Sharing (ICS).
  4. USB-C Cable that comes with the EnSURE Touch.
  5. Windows 10 knowledge and ability to navigate to Device Manager and Windows Network Connections.


  1. Only one EnSURE Touch can be connected at a time. You can configure multiple instruments on one computer, but only one can be connected at a time.
  2. Once configured, disconnecting the EnSURE Touch will remove the network adapter from Windows 10. Reconnecting the EnSURE Touch to the Windows 10 computer will reestablish the network adapter and ICS setting, but there is a short delay. The delay is about 30 seconds depending on the computer. Attempting to Sync or perform any network functions during this delay will result in failure. The failure can be dismissed.
  3. USB Tethering has not been tested on every Windows 10 computer. Success is dependent on the Windows 10 computer ability to support the network adapter driver and ICS configuration.
  4. Windows 10 computer BIOS, drivers, and Windows updates may be required.
  5. 3rd party software firewalls may block ICS.
  6. TeamViewer support on EnSURE Touch does not work with USB Tethering

Configuration Steps

The following are the steps to enable USB Tethering. Each EnSURE Touch has a unique serial number that is bound to the Windows RNDIS driver. This means the Windows steps below must be done for each EnSURE Touch that will be connected to this computer. Once the configuration is complete, disconnecting and reconnecting the EnSURE Touch will reestablish the network adapter ICS settings. This typically takes less than 30 seconds.
