3. Option of Trigger Modes
There are 3 trigger modes available for users to choose according to the actual needs. Any of these 3 trigger modes
can be set / acquired through a configuration file named “read.cfg”, which comes from a text file(.txt) originally. Users
just need to fill in a digit / parameter that is corresponding to a trigger mode in a new built text file. Save it and
rename it “read.cfg”, then put it in the root directory of the flash memory together with the 4 audio files. Please refer
to the sheet below about the digits and the associated trigger modes.
Pulse interruptible one-on-one playback: In this mode, a single negative pulse will start playback.
It is possible to interrupt the playback by pressing the same button used to activate. Once
playback is interrupted, it will automatically restart the audio file immediately. It’s also
possible to interrupt the play back by pressing any of the other 3 buttons. Once playback is
interrupted, it will automatically start the sound that is associated with the button pressed.
Level hold loop playback: In this mode, the negative pulse must be held/maintained to the
sound module trigger for audio file to complete. The audio file will only playback while button,
or negative pulse, is held/maintained during playback. Once the button being held, or
negative pulse, is removed, the playback will be stopped/cancelled. Once the button is kept
holding, when the playback of the audio file is finished, it will start to play it repeatedly(loop
playback).
Pulse non-interruptible one-on-one playback: In this mode, a single negative pulse will start
playback.It's not possible to interrupt the playback by pressing the same button or the other
buttons. Once an audio file is triggered, the audio file will not be able to be
interrupted/cancelled during playback. The playback will only end when the audio file has
played its entirety.
For example, if the trigger mode of level hold loop playback is needed, firstly build a new TXT file on the computer, and
simply enter the digit “1” as below, and save the file.

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.

4 audio files need to be directly stored in the root directory of the flash memory. No folders can be in the root
directory. The arrangements of the audio files are managed by a physical indexing sequence. In other words, the file
that is to be loaded first in the internal memory will be associated with input 1. The last file to be loaded in the internal
memory will be associated with input 4. 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 the 4 audio files into this new folder.
2). Rename the audio files from 001.mp3 to “004.mp3”, and make sure they are ranked from “001.mp3” to “004.mp3”
in order.
3). Connect the player with computer through the USB cable, and you will see a simulated USB flash drive.
4). Delete the sample audio files pre-loaded at factory for testing purpose.
5). Back to the folder and select all of the 4 audio files in the folder.
6). Right click on the first file (001.mp3) and choose "Send to removable disk".
7). In this way it will send the 4 audio files to the memory in a correct sequence.
8). Put the configuration file with the trigger mode needed into the root directory together with audio files as below,
then refresh.
9). Safely remove the simulated USB flash drive (internal memory of the player) from computer.
6). Apply power to the player and push any of 4 keys / buttons to play back an associated sound.
