GENERAL DESCRIPTION
The AKD4103A-B is an evaluation board for the AK4103A, 192kHz DIT. The AKD4103A-B has the interface
with AKM’s A/D converter evaluation boards and AKM’s DIR evaluation boards. Therefore, it is easy to evaluate
the AK4103A. The AKD4103A-B also has the digital audio interface and can achieve the interface with digital
audio systems via BNC unbalance or XLR balance connector.

B, C, U, V Inputs (at synchronous mode)
At synchronous mode (ANS=1), C(channel status), U(user data) and V(validity) are input via 10pin header (PORT3:
BCUV). BLS is output at normal mode (TRANS=0), and is input at audio routing mode (TRANS=1). In case of
audio routing mode, BLS, C, U an V can be directly input from the AKD4114 via 10-line flat cable. The pin layout of
PORT3 is shown in Figure 2.

Control Soft Manual
Evaluation Board and Control Soft Settings
1. Set an evaluation board properly.
2. Connect a USB control box (AKUSBIF-B) and an evaluation board.
Pay attention about direction of the 10pin header when connecting to an AKUSBIF-B.
3. Connect a PC (IBM-AT compatible) and the USB control box (AKUSBIF-B).
The USB control box is recognized as HID (Human Interface Device) on the PC.
It is not necessary to install a new driver.
4. Start up the control program.
When the screen does not display “AKUSBIF-B” at bottom left, reconnect the PC and the USB control box, and push
the [Port Reset] button.
5. Proceed evaluation by following the process below.
[Support OS]
Windows XP / Vista / 7 (32bit) (XP compatible mode is recommended for Vista / 7)

■Operation Overview
Function, register map and testing tool can be controlled by this control soft. These controls are selected by upper tabs.
Buttons which are frequently used such as register initializing button “Write Default”, are located outside of the
switching tab window. Refer to the “■ Dialog Boxes” for details of each dialog box setting.
1. [Port Reset]: For when connecting to USB I/F board (AKDUSBIF-B)
Click this button after the control soft starts up when connecting USB I/F board (AKDUSBIF-B).
2. [Write Default]: Initializes Registers
When the device is reset by a hardware reset, use this button to initialize the registers.
3. [All Write]: Executes write commands for all registers displayed.
4. [All Read]: Executes read commands for all registers displayed.
5. [Save]: Saves current register settings to a file.
6. [Load]: Executes data write from a saved file.
7. [All Req Write]: Opens “All Req Write” dialog box.
8. [Data R/W]: Opens “Data R/W” dialog box
9. [Sequence]: Opens “Sequence” dialog box.
10. [Sequence(File)]: Opens “Sequence(File)” dialog box.
11. [Read]: Reads current register settings and displays on to the register area (on the right of the main window).
This is different from [All Read] button, it does not reflect to a register map, only displaying register
settings in hexadecimal.
