Recommended Approach

If you need to upgrade or roll back the Serial Solutions driver, we recommend completely uninstalling the existing drivers first, and then installing the new drivers from fresh. This will restore all the factory settings to default.

However, if you wish to keep all of your existing settings, you can use the Update Driver or Rollback Driver options in Device Manager.

Upgrading the Serial Solutions Driver​

  1. Go to Device Manager and right-click on the Serial Card entry (Found under Multiport Serial Adaptors - see image below).

  2. Repeat this for every Serial card and port entry.
