3. Operation Guide

3.1. Set Trigger Mode and Volume

There are 4 trigger modes and 31 volume levels available for users to set in a configuration file according to the actual needs.

Trigger Modes

Each of the parameters from “0” to “3” represents a corresponding trigger mode. See the details below.



Pulse interruptible one-on-one playback: In this mode, a single negative pulse (caused by motion sensor for example )
will trigger playing of an MP3 sound file. Playback can be interrupted by triggering another pulse (by re-triggering the

motion sensor) which will then cause the playback to restart immediately and play until complete.

 Level hold loop playback: In this mode, the negative pulse must be held/maintained to the sound module

Example: A motion detector senses continual motion within a room, triggering the audio file to play. Once the motion

stops, playback will be cancelled.



Pulse non-interruptible one-on-one playback: In this mode, a single negative pulse will start playback. It is

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 in its entirety.



Standard MP3 key mode playback: In this mode, the four inputs on the E-TMAPS-10W will function as

Previous, Next, Play/pause, and Stop triggers respectively, allowing more than four audio files to be placed
on the device.

Volume Levels

Each of the parameters “00” to “30” represents a volume level. “00” represents mute while “30” represents the max. Volume level.

Any of these 4 trigger modes and 31 volume levels can be set through a configuration file named “read.cfg”, which comes from a

text file(.txt) originally. Please refer to the two steps below on how to build a configuration file successfully. Let’s take the trigger

mode ”level hold loop playback” and volume level “20” as an example.

1). Build a new text file on computer and enter the corresponding number “120” that represents the trigger mode ”level hold loop

playback” and volume level “20”. Refer to the image below.

volume level

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 will not work. Refer to the image below.

Example: A motion detector senses when a person enters a room, which triggers the audio player to play the MP3
sound file. Once the audio file is triggered, the playback will only end once the file has played in its entirety.
