5 Function

As indicated above, AEC-4420P/4420PB is connected to an ACARD copy control-

ler via link mode control. Generally, when the copy controller is standalone, Q-

Switch is connected to IDE connector. But when the copy controller is to be link

host, Q-Switch will be switched to USB Bridge through link mode control, and thus

4420P/4420PB will be connected to PC. In link host mode, the device that PC con-

trols is either a CD/DVD writer or a hard drive connected to the IDE bus on Q-

Switch.
