4.2 Pasos de conexión

  1. Conexión de la fuente de alimentación: Connect a DC12V-24V power supply to the "INPUT: DC12V-DC24V" terminals. Ensure correct polarity (V+ to positive, V- to negative). The maximum output current is 3x8A, so ensure your power supply can handle the total load of your LED lights.
  2. Conexión de salida LED: Connect your LED lighting products (e.g., RGB LED strips) to the "OUTPUT: CH1, CH2, CH3" terminals. For RGB strips, connect Red to CH1, Green to CH2, Blue to CH3, and the common anode to V+. For single-color lights, connect to any channel. Ensure the total current for each channel does not exceed 8A.
  3. DMX Signal Input:
    • Conexión XLR: Connect your DMX controller's output to the "DMX512 IN" XLR port. If daisy-chaining multiple decoders, connect the "DMX512 OUT" of the first decoder to the "DMX512 IN" of the next.
    • Conexión RJ45: Alternatively, use a Cat5 Ethernet cable to connect your DMX controller to the RJ45 input port. The RJ45 ports are wired for standard DMX pin locations.
  4. Encendido: Once all connections are secure, apply power to the decoder. The digital display will illuminate.

5. Instrucciones de funcionamiento

The AMKI DMX512 Decoder offers DMX mode and several built-in static/dynamic modes. The digital display and buttons are used for configuration.

5.1 Setting DMX Address (A Mode)

In DMX mode, the decoder responds to DMX signals starting from a specific address. This is the default operating mode.

  1. When powered on, the display will typically show an 'A' followed by a four-digit number (e.g., A001). This indicates the current DMX start address.
  2. Presione el COLOCAR button to enter address setting mode. The digits will flash.
  3. Utilice el + y - buttons to adjust the DMX start address (range A001 to A512).
  4. Presione el COLOCAR button again to confirm and save the address. The display will stop flashing.
  5. The decoder will now respond to DMX signals on the set address and the subsequent two channels (for a 3-channel device). For example, if set to A001, it will use DMX channels 1, 2, and 3.

5.2 Built-in Modes (H Mode)

The decoder includes pre-programmed static and dynamic lighting effects. These modes disable DMX control.

  1. From DMX address setting mode (A mode), press the COLOCAR button repeatedly until the display shows 'H' followed by a two-digit number (e.g., H-01). This indicates the built-in mode selection.
  2. Utilice el + y - buttons to cycle through the available built-in modes (H-01 to H-11). Each mode represents a different static color or dynamic effect.
  3. Presione el COLOCAR button to confirm the selected mode.

5.3 Adjusting Speed/Brightness (S Mode)

For dynamic built-in modes, you can adjust the speed. For static built-in modes, this may adjust brightness.

  1. While in a built-in mode (H mode), press the COLOCAR button again until the display shows 'S' followed by a two-digit number (e.g., S-01). This indicates speed/brightness adjustment.
  2. Utilice el + y - buttons to adjust the speed or brightness level (S-01 to S-20).
  3. Presione el COLOCAR Botón para confirmar la configuración.

Note: To return to DMX control, you must manually set the device back to 'A' mode and select a DMX address. The device will retain its last setting upon power cycle.

6. Mantenimiento

  • Mantenga el dispositivo limpio y sin polvo. Utilice un paño suave y seco para limpiarlo.
  • Asegúrese de que todas las conexiones estén seguras y libres de corrosión.
  • Guarde el dispositivo en un entorno seco y fresco cuando no esté en uso.
