3.1. Set Work Mode
There are 7 main trigger modes (from “0” to “6”) and 5 auxiliary modes (from “7” to “B”) available for users to set in a
configuration file according to the actual needs
Each of the parameters from “0” to “B” represents a corresponding trigger mode, which can be set individually for
each of the 4 trigger inputs. See the details below.
Detailed Explanations on the Main Trigger Modes 0-6
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/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: 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.
Hold and Play Once: 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 not start to play it again.
All in Loop: In this mode, a single negative pulse will start playback.Press the button and it’s
able to play all the audio files in the storage device one by one in loop. During playback, if the the
same button is pressed again, the playback will be stopped. In addition, if the associated trigger
input is shortened with GND first, the player will automatically play the audio files one by one in
loop once it is powered on.
Play Next in Associated Folder: In this mode, a single negative pulse will start playback.Every
time press the button and it’s able to play next audio file and stops when the audio file is finished
in the associated folder. During playback, if the the same button is pressed again, the playback
will be interrupted and it will activate the next audio file at the same time. In this mode, as many
as 100 audio files can be loaded into the folder.
Single in Loop: In this mode, a single negative pulse will start playback.Press the button and it’s
able to play the associated audio file in loop. During playback, if the the same button is pressed
again, the playback will be stopped.
Any of these 12 work modes can be set for any of the 4 trigger inputs through a configuration file named “read.cfg”,
which comes from a text file(.txt) originally. In the configuration file, each digit that represents the work mode is
associated with one trigger input, so there are total of 4 digits that associate 4 trigger inputs respectively. Please
refer to the two steps below on how to build a configuration file successfully.
1). Build a new text file on computer and enter the corresponding number like “0113” that represents the input 1 will

be set with the trigger mode “Pulse Interruptible”, input 2 and input 3 will be set with the trigger mode “Hold and Play
in Loop”, input 4 will be set with the trigger mode “Hold and Play Once”. 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.
3.2. Audio Files Loading
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 configuration file. Once the connection is done, the internal
flash memory will be detected and displayed on PC working as a USB flash drive.

Except for the trigger mode 5 (Play Next in Associated Folder) that supports multiple audio files, all of the other 6
main trigger modes(0-4, and 6) work based on one-on-one control. 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 storage device will
be associated with input 1. The last file to be loaded in the storage device 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 equipment with computer through the USB cable, and you will see a removable disk / 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 / USB flash drive”.
7). This should send the 4 audio files to the memory in a correct sequence.
8). Put the prepared configuration file into the root directory together with audio files and then refresh.
Refer to the image below.
9). Safely remove the USB data cable from computer.
10). Apply power to the equipment and push any of 4 wired buttons to play back a corresponding sound.
Note: Any of the 5 auxiliary modes (from “7” to “B”) can be set for any of the 4 trigger inputs as well if
required.
4.2.2. Files Loading Method for Triggering Mode 5
The trigger mode 5 (Play Next in Folder) is a special feature of this device that is able to meet some special
applications. When building the configuration file, please fill in the number “5555”. In this way all of the 4 trigger
inputs will be worked in mode 5 (Play Next in Folder). It’s also fine if you just want the first 2 trigger inputs to be
worked in mode 5, and the other 2 trigger inputs to be worked in the other modes like filling in the number”5512”.

Let’s take all of the 4 trigger inputs to be worked in mode 5 as example. Please refer to the steps below on how to
load the audio files.
1). Firstly connect the device to computer using the USB cable, and you will see a removable disk / USB flash drive.
2). Build 4 new folders in the memory and rename them 01, 02, 03, and 04. The first trigger input will be associated with
the folder 01, the second trigger input will be associated with the folder 02,...and the fourth trigger input will be
associated with folder 04. Refer to the image below.
3). Respectively copy audio files from computer to the associated folder. The audio files in the folders can be renamed
as 001.mp3, 002.mp3, 003.mp3.....It also works if you don’t change the names.
4). Put the prepared configuration file into the root directory together with the folders and then refresh. Refer to the
image below.
5). Safely remove the device from computer.
6). Apply power to the equipment and push any of 4 buttons to play back a sound from the associated folder.

4. Schematic of Connection
4.1. Connection for Normal Use
4.2. Connection for Automatic Loop Playback When Powered Up
This wiring method is for those customers’ reference, who need the player to play the sound messages automatically in
a loop once it’s powered up. Besides, to achieve this function the trigger mode in the configuration file must be “4” for
the first trigger input only.
6. Installation
As the picture is shown below either you can use two screws or use a sticker to install / fix the player easily.
