Gigabit vs USB connection

TDT system 3 hardware can be connected to the computer with two different types of connection:

Gigabit: This is a specialized connection that requires a dedicated PCI card in the controlling computer. This is the default connection type. To connect using gigabit you should use either project = DSPProject() or more explicit project = DSPProject(interface='GB')

USB: This is a standard USB connection. If you are connecting your system 3 with USB you need to state it explicitly. project = DSPProject(interface='USB')
