Introduction
The K20W Sound Writer Programmer is designed to support the following IC:
-K161004 (10 sec, 4 I/O OTP chip)
-K162104 (21 sec, 4 I/O OTP chip)
-K164208 (42 sec, 8 I/O OTP chip)
-K208511 (85 sec, 11 I/O OTP chip)
-K2N341N (341 sec, 15 I/O OTP chip)
This development system serves two main functions:
Compiler –to created a DAT file from user’s sound files
Writer –to program the DAT file into the voice chip
The Compiler is used to combine the edited sound files into the chip to form the desired
Voice Group and to define the playback functions of each Voice Group by selecting
different Options and Trigger Modes of each individual Voice Group.
The Writer is used to program the voice data into the voice chips that resulted from the
Compiler Function. The Writer must be connected to the PC to use the program.
System Requirement
This program only works with Windows XP and a computer with USB connector.
Installation
Installing the USB driver
If this is the first using this program, after connecting the USB cable to the computer, you
will be asked to install the USB driver. Follow the instructions on the screen to install the
USB driver.
Installing the Software
Create a new folder on your computer. Copy the K20W_Vxxx_yyyymmddtttt.ZIP to the
folder, where “xxx” represents the version number and “yyyymmddttt” represents the date
and time of the software. Unzip the file into the folder.

Writer Board Connection
1) Connect the USB cable from the writer board to the computer. The computer will display
a new hardware is found message. The installation will begin automatically.
2) If there are too many USB devices connected to your computer at the same time, the
current supply from USB may not be sufficient to support the Writer. In this case, an
external 5V DC adapter with at least 1A capacity should be connected separately to the
power jack (center positive) of the Writer.
3) The power LED will be turned ON
4) The BUSY LED will be turned ON

Running the Software
Double click the file K20W.EXE to launch the software. The software will start and check
the firmware version on the Writer Programmer board. The following Window will be
displayed (Fig. 2).

Update Firmware
If the firmware version is correct, the program starts automatically. If the Firmware version
is not correct, it will display a firmware update window to automatically update the firmware
(Fig. 3).
Fig. 3
Press Y to continue. Then a warning window as shown in Fig. 4 will be displayed as a
reminder to not disconnect the USB cable during the firmware update. Otherwise, the
Writer Programmer board will be damaged permanently. Press OK to begin the update
process.
Fig. 4
In case of firmware update failure, an error message window as shown in Fig. 5 will be
displayed. If this happens, press Cancel and connect the Writer Programmer board to
another USB port of the computer and try to start the program again. Some USB ports of
the computer may not have enough power for the firmware update to perform.
Fig. 5
If the firmware update is completed successfully, the software starts automatically.

Compiler Window
When the K20W USB Sound Writer is launched, the Compiler Window is displayed. The
Compiler Window consists of the following areas:
-Device Selection: to select which voice chip to be used
-Trigger Selection: to determine how the chip to be triggered
-Voice Output Type: to select the type of voice output, VOUT or COUT
-VOUT Volume: VOUT volume can be selected in some of the voice chip
-Pin Status Display:shows the pins status
-File Display Area: displays a list of sound files used
-Voice Group Listing: shows the available voice groups and the trigger options
-Function Buttons: to perform the specific functions
-Memory Usage: displays in percentage how much memory is used
Fig. 6
Voice data and user selectable options must be set up and combined together to create a
DAT file for programming into the voice chip. The following procedures describe step by
step how to compile the voice data and select the options to produce the DAT file for
programming.

Step 1 –Select Device
-Click the pulldown list to show a list of devices and select the device you want to
work on.
Step 2 –Select Trigger Mode
-Select the type of Trigger Mode you want. For more information, see Trigger Options
or Triggering examples.
Step 3 –Select Voice Playback Volume Type

Step 4 –Select Voice Compress Type
-Click the pulldown list to select the compress type for the input sound file. Lower bit
compression such as 4-bit ADPCM, takes less memory space to store the sound file.
However, the sound quality is better with higher bit compression.
