AK4683 Evaluation Board Rev.1
AKD4683-A -- AK4683 Evaluation Board 10 wire flat cable for connection with printer port of PC (IBM-AT compatible machine), control software for AK4589, driver for control software on Windows 2000 / XP are packed with this. Control software does not work on Windows NT Windows 2000 / XP needs an installation of driver. Windows 95 / 98 / ME does not need an installation of driver. AK4683 supports the standard-mode I2C-bus (max: 100kHz), and does not support a fast-mode I2C-bus system (max: 400kHz).
FUNCTION On-board clock generator (use AK4114, x2) Compatible with 2 types of digital audio interface - Optical output / input and RCA input / output - 10pin header for interface with external data source (x2) RCA connector for clock input with external clock source 10pin header for register control

2. Register control
2-1. 10-wire flat cable for register control AK4683 can be controlled via printer port (parallel port) of IBM-AT compatible PC. Connect printer port (parallel port) of PC and PORT2 (uP-I / F) of AKD4683-A by 10-wire flat cable (packed with AKD4683-A). Take care of the direction of 10-pin connector and 10-pin header. (The red line side of 10-wire flat cable of 10-pin connector should be connected to No.5pin and No.6pin of 10-pin header.)

AKD4683 (DIR / DIT) part Control Program operation manual
Set-up of evaluation board and control software
(Note) Control software does not work on Windows NT Windows 2000 / XP needs an installation of driver. Windows 95 / 98 / ME does not need an installation of driver. Please refer to "Installation Manual of Control Software Driver by AKM device control software", about the method of installation of driver. AK4683 supports the standard-mode I2C-bus (max: 100kHz), and does not support a fast-mode I2C-bus system (max: 400kHz).
Operation flow
Keep the following flow. 1. 2. 3. Set up the control program according to explanation above. Click Write default button. Then set up the dialog and input data and evaluate AK4683 (DIR / DIT) part.

Indication of data
Input data is indicated on the register map. Red letter indicates "H" or "1" and blue letter indicates "L" or "0". Blank is the part that is not defined in the datasheet.
Attention on the operation
Input data to all boxes when you have set up "Function1 dialog". An "attention dialog" is indicated if you input data or address that is not specified in the datasheet or you click "OK" button before you input data. In that case set up the dialog and input data once more again. These operations does not need if you click "Cancel" button or check the check box.
