Complex Logic Connection Example
Table 2-7 and Figures 2-39 and 2-40 show 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.
