And change the file name "xxx.txt" to "read.cfg" as below, then the configuration file with level hold loop playback mode is
made successfully. Please be noted the extension name".txt" of the text file must be changed to ".cfg", otherwise the
configuration will not work.
Note: The factory default triggering mode is "pulse interruptible", so it's also workable even though you don't put the
configuration file for "pulse interruptible".
3.2. 'One-on-one' sound file triggering control (for direct playback of the associated sound file)
The 20 sound files need to be directly stored in the root directory of the on-board flash memory or the micro SD card. No other
folders can be in the 'root directory'. The arrangements of the sound files are managed by a physical indexing sequence. In other
words, the file that is to be loaded first in the storage device will be associated with input "K1". The last file to be loaded in the
storage device will be associated with input "K20". In order to guarantee a correct 'one-on-one' order, please refer to the following
steps.
1). Build a new folder on the computer and put 20 sound files in this new folder.
2). Rename the audio files from 001.mp3/wav to "020.mp3/wav", and make sure they are ranked from "001.mp3/wav" to
"020.mp3/wav" in order.
3). Connect the module with computer through a USB data cable and you will see a simulated USB flash drive on computer.
4). Delete the pre-loaded files for testing purpose at factory. If using a micro SD card, please format it to FAT32 at this step.
5). Go back to the folder on computer and select all the sound files in the folder.
6). Right click on the first file (001.mp3/wav) and choose "Send to removable disk".
7). This should send the 20 sound files to the on-board flash memory or the micro SD card in a correct order.
8). Once the files transfer is complete, put the configuration file in the on-board flash memory or the micro SD card together
with the sound files as below.
