COMPLEX LOGIC CONNECTION EXAMPLE
This example shows a device with more complex logic functions like that typically found in a computer
playback system. On most peripheral devices, the logic ground and +5 volt supply connections are not used, but
in this example the playback system logic I/O connections are also isolated.
