Hello.
The values listed in the “Connected to:” drop-down menu are the serial numbers of each Maestro unit connected to your computer. The device number can be found under the “Serial Settings” tab in the Maestro Control Center.
As for sample code, there is another member who shared his code for communicating with a Maestro servo controller from Visual Basic 6.0 that you might find useful.
If you continue to have issues, you can post your code and pictures of your setup, and I would be happy to take a look.
