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.
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.
Any of these 4 work modes can be set for any of the 7 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 7 digits that associate 7 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 “0011221” that represents the input 1 and input 2
will be set with the trigger mode “Pulse Interruptible”, input 3, input 4 and input 7 will be set with the trigger mode “Hold and Play
in Loop” , input 5 and input 6 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.
3.2. Audio Files Loading
As you see there is a micro USB socket on the device, and you can connect it to computer through an Android phone purposed USB
cable to load audio files and configuration file. When it’s connected with PC, the built-in flash memory will be detected and displayed
on PC working as a USB flash drive.
7 audio files (or fewer according to actual requirement) 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
