Install the software by following the instructions on the SquirrelView Installation Guide.
Connect the 2020/2040 to the PC via either USB or Serial connections. If you are using USB

Hardware Installation warning that refers to Windows Logo testing.

Click on the shortcut icon on your desktop to launch SquirrelView or select it from your start
menu - Program group menu within Windows. When the SquirrelView Assistant has opened,
ensure the correct logger type and communication method is selected. This can be viewed in
