3. Option of Trigger Modes
There are 4 trigger modes available for users to set in a config file according to the actual needs. Each of the
parameter from “0” to “3” represents a corresponding trigger mode, which can be set individually for each of the 4
trigger inputs. See the details below.
Detailed Explanations
Pulse Interruptible: 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.
Hold and Play in Loop: 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/canceled. 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: 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/canceled during playback. The playback
will only end when the audio file has played its entirety.
All in Loop: In this mode, a single negative pulse will start playback.Press the button and it’s

input is shortened with GND first, the player will automatically play the audio files one by one in
loop once it is powered on.
Any of these 4 trigger modes can be set for any of the 4 trigger inputs through a config file named “read.cfg”, which
comes from a text file(.txt) originally. In the config file, each digit that represents the trigger mode is associated with a
trigger input port, so there are total of 4 digits that associate 4 trigger input ports respectively. Please refer to the two
steps below on how to create a config file successfully.
1). Create a new text file (.txt) on computer and enter the corresponding number like “0012” that represents the input
1 and input 2 will be set with the trigger mode “Pulse Interruptible”, input 3 will be set with the trigger mode “Hold and
Play in Loop” , input 4 will be set with the trigger mode “Pulse Non-interruptible”. Refer to the image below.
2). Save it and change the file name “xxx.txt” to “read.cfg”. Please make sure your computer shows filename
extensions. The extension “.txt” must be changed to “.cfg’’, otherwise the file is not workable. Refer to the image
below.
Note: If there is no config file on the memory, the player works under the mode “Pulse Interruptible” by
default.

As you can see the picture above, there is a micro USB port, and you can connect it to computer through an Android
phone purposed USB data cable to load audio files and config file. Once the connection is done, the internal flash
memory will be detected and displayed on PC working as a USB flash drive.
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). Create a new folder on 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 / Send to USB flash drive".
7). In this way it will send the 4 audio files to the memory in a correct sequence.
8). Put the config file with the trigger mode needed onto the root directory together with audio files as below,
then refresh.
