The GDI/USB PWB has two circuits; one for transmitting and receiving
IEEE1284 signals and the other for transmitting and receiving USB sig­nals and converting USB signals into IEEE1284 signals.

IC601, 602 and 603 are connected between IEEE1284 an ASIC to con­vert signals.

IC501 transmits and receives USB signals and converts USB signals
into IEEE1284 signals.

IC502 stores various setup data necessary for USB operation of IC501.

IC503 informs the CPU of connection of USB. It is connected with PC
via a USB cable. When 5V is inputted from PC to the IC’s input pin,
the output pin (signal name: USB-IN) is driven to HIGH to inform the
CPU of connection of USB.

IC504 detects connection with PC via a USB cable, supplies power to
the USB port signal line (signal name: DATA+) to enable USB com­munication.

When USB is connected, the CPU enables USB and disables
IEEE1284.

(When USB is enabled, IE1284 is disabled.)
