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 easily through a configuration file, which is a text document (.txt). Users just need to fill in a number/numerical value that is corresponding to a trigger mode in a new built text file. Save it and rename it “Config.txt” or other name you like, then put it together with the audio files in the root directory of the built-in flash memory. Please refer to the sheet below about the numerical values and the associated trigger modes.
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 playback by pressing any of the other 2 buttons. Once playback is interrupted, it will automatically start the sound that is associated with the button pressed.
Level hold for 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 play back while button, or negative pulse, is held/maintained. 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 is uninterruptible
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.
Examples of Connections
1. Connection for Key Control
2. Connection for Automatic Loop Playback When Powered On
Note: Get the yellow wire (first trigger input) with the black wire (ground) short-circuited, and use the number “1”in the config file.
