4. Configuració

4.1 Connexió del cablejat

Refer to the diagram below for proper wiring of the module. Ensure all connections are secure before applying power.

Wiring diagram for DY-HL30T module showing connections for power input (DC 9V-24V), 4-8ohm speaker, lamp, playing indicator, power indicator, Micro USB, adjust volume potentiometer, switch module (DIP switch), TF card socket, and 9 trigger inputs (S1-S9) with a common ground (GND). — Detailed Wiring Diagram for the DY-HL30T Module.

GND/COM: This is the common terminal for trigger signals.
S1-S9: These are the 9 trigger input pins. Each pin can be configured to play a specific audio file (e.g., S1 for 00001.mp3, S2 for 00002.mp3, etc.). These are low-level trigger inputs, meaning they are triggered by connecting them to GND.
9-24V Terminal: Connect your DC 9V-24V power supply here.
Ponent: Connect your 4-8ohm speaker to these terminals. The module supports 10W-30W speakers.
Light/Alarm Output: This output provides voltage identical to the input work voltage and can be used to connect external alarm or warning lights.
Playing Indicator: Green LED indicates power is ON, Red LED indicates playback.
Micro USB Socket: Used to connect the module to a PC for downloading music files.
Ajustar el volum: A potentiometer allows for volume adjustment.
Switch Module (DIP Switch): A 3-bit red toggle switch (ON DP 1 2 3) is used to set the 8 different triggering modes.
Socket de targeta TF: Insert a TF memory card (up to 32GB) here for audio file emmagatzematge.

4.2 TF Card Preparation

The module requires a TF (MicroSD) card for storing audio files. Please follow these guidelines:

Format: The TF card must be formatted to FAT32. NTFS format is not supported.
File Denominació: Àudio files (MP3 or WAV) must be named as 5-digit numbers, for exampel, 00001.mp3, 00002.mp3, up to 00009.mp3.
File Transferència: After inserting the TF card into the module and connecting the module to a computer via a USB data cable, the TF card will be recognized as a removable disk (U disk). You can then directly copy audio files to the TF card.
Inter-Cut Trigger Mode: If using the Inter-Cut Trigger mode, background music should be stored in the root directory, and insert music must be placed in a folder named "CHABO". For other play modes, a "CHABO" folder is not required.

The laptop screen displays audio files named 00001.mp3, 00002.mp3, 00003.mp3, etc., indicating how to copy files to the TF card. A note emphasizes that the TF card must be in FAT32 format. — Instructions for connecting the module to a computer and copying audio files to the TF card.

5. Instruccions de funcionament

5.1 Work Modes Configuration

The DY-HL30T module offers 9 different work modes, configured using the 3-bit red DIP switch. Important: The power must be restarted after changing the DIP switch settings for the new mode to take effect.

Table detailing 9 different work modes for the DY-HL30T module, controlled by a 3-bit DIP switch. Each mode (Level Trigger Non-interruptible, Level Trigger Interruptible, Pulse Trigger Non-interruptible, Pulse Trigger Interruptible, Level Keep Trigger, Play or Pause Trigger, Inter-Cut Trigger, MP3 Mode 1, MP3 Mode 2) has a corresponding DIP switch setting, function description, and applicable scenarios. — DIP Switch Settings and Corresponding Work Modes.

Here is a summary of the work modes:

Mode de treball	Descripció de la funció	Escenaris aplicables
Level Trigger Non-interruptible	Input trigger signal to start playing. Stop after playing once. Input trigger signal again is invalid during playing. Loop playback if input signal is kept.	Cannot be interrupted by other signals during playing. Only the first triggered signal plays when multiple signals are triggered simultaneously.
Level Trigger Interruptible	Input trigger signal to start playing. Stop after playing once. Replay music after input trigger signal again during playing. Loop playback if input signal is kept.	Immediately replays music upon receiving a signal. Only the last triggered signal plays when multiple signals are triggered simultaneously.
Pulse Trigger Non-interruptible	Input trigger signal to start playing. Stop after playing once. Input trigger signal again is invalid during playing. Plays just once even if input signal is kept.	Plays music in the order of triggering when multiple signals are triggered simultaneously.
Pulse Trigger Interruptible	Input trigger signal to start playing. Stop after playing once. Replay music after input trigger signal again during playing. Plays just once even if input signal is kept.	Immediately replays music upon receiving a signal. Only the last triggered signal plays when multiple signals are triggered simultaneously.
Level Keep Trigger	Plays when input signal is kept. Stops immediately if input signal is removed. Input other trigger signals again is invalid during playing.	Signal hold trigger.
Play/Pause Trigger	Input trigger signal to start playing and keep loop playback. Input trigger signal again to stop. Restarts playback after input trigger signal again during stopping.	Self-locking playback.
Inter-Cut Trigger	Plays music in folder CHABO in root directory. S1-S9 can trigger music in folder CHABO after input trigger signal. Plays background music after power ON. Input trigger signal again is invalid during playing.	Background music names cannot be 00001.mp3 to 00009.mp3. Replays background music after inter-cut music. S1-S9 can trigger music 00001.mp3 to 00009.mp3 in folder CHABO.
MP3 Mode 1	S1: Connect to GND. S2: Next Music. S3: Prev Music. S4: VOL+. S5: VOL-.	Input trigger signal to start playing. Stop after playing once. Play in order of music files. Potentiometer adjusts the upper limit of the maximum volume.

8. Consells d'usuari

The trigger inputs (S1-S9) are low-level triggers, meaning they respond to a GND signal.
Always power cycle the module after changing the DIP switch settings to ensure the new mode is applied.
For the Inter-Cut Trigger mode, ensure background music is in the root directory and insert music is in the "CHABO" folder. For other modes, a "CHABO" folder is not necessary.
Verify that your TF card is formatted to FAT32 and not NTFS for proper operation.
Assegureu-vos l'àudio files are named with 5 digits (e.g., 00001.mp3) for correct recognition and playback.

9. Solució De Problemes

Sense so: Check power supply (9V-24V DC), speaker connection (4-8ohm), and ensure the volume potentiometer is not set to minimum. Verify TF card is inserted and contains correctly named audio files.
Incorrect Playback Mode: Ensure the DIP switch settings match your desired work mode and that the module was power cycled after changing the settings.
FileNo s'està reproduint: Confirm TF card is FAT32 formatted. Check that audio files are MP3 or WAV format and named with 5 digits (e.g., 00001.mp3). If using Inter-Cut Trigger mode, verify folder structure for background and insert music.
Module Not Recognized by PC: Ensure the Micro USB cable is functional and properly connected. Try a different USB port or cable.
