[AKD4588]
„ Jumper setting
[JP1] (GND): Analog grand and digital grand
Open: Analog grand and digital grand is separated. < Default>
Short: Analog grand and digital grand is common. “DGND” jack is able to open at this time.
„ Operation of toggle switch.
[SW1](PDN): Resetting of AK4588. It must be “H” during operation this board.
„ Indication of LED
It turns on each pin when each pin output is “H”.
[LE1] (INT0): Indicate of AK4588’s INT0 pin output.
[LE2] (INT1): Indicate of AK4588’s INT1 pin output.
„ Serial Control
The AK4588 can be controlled via the printer port (parallel port) of IBM-AT compatible PC. Connect PORT1
(uP-I/F) with PC by 10 wire flat cable packed with the AKD4588.
Be careful connector direction. Flat cable should be connected 10-pin header, red line put on 10pin header 5 and 6
pin.
