Technical Specifications

The D2-CX is a professional-grade 2-channel DMX512 decoder engineered for precise, reliable control of constant voltage LED lighting. As a key component for any serious DMX512 control system, this decoder seamlessly translates standard DMX signals into smooth PWM dimming for two independent channels. Its dual-channel design makes it the perfect solution for managing dual white CCT LED strips, allowing you to dynamically adjust color temperature from warm to cool white. It can also be used to control two separate zones of single-color LED strips. Featuring both DMX512 and RDM protocols, the D2-CX offers both standard control and advanced remote device management, simplifying configuration and monitoring in complex installations. With a robust 10A per channel output, it provides ample power for demanding architectural, stage, and commercial lighting projects.

Application Scenarios

Tunable White Architectural Lighting Ideal for residential and commercial spaces requiring dynamic mood lighting. Use the D2-CX to precisely control dual white CCT LED strips in coves, under cabinets, and in linear fixtures to shift from a cozy warm white to a productive cool white.
Theatrical & Stage Accents In performance environments, this decoder provides reliable DMX512 control for two separate single-color lighting zones. Perfect for backdrops, set pieces, or accent lighting where two distinct colors or areas need independent dimming control from a main console.
Retail & Exhibit Displays Create engaging product displays by using two channels to control different aspects of the lighting. For example, use one channel for primary illumination and the second for a subtle accent, all managed through a centralized DMX512 system for easy scene changes.

How to Control & Use This DMX512 Decoder

  1. Power Connection: Connect a suitable DC12V or DC24V power supply to the V+ and V- input terminals. Ensure the voltage matches your LED strips.
  2. DMX Signal: Connect your DMX512 master controller to the DMX signal input terminals or RJ45 port.
  3. LED Strip Wiring: Connect your constant voltage LED strips to the output terminals. For CCT strips, connect the common V+ wire, then connect the warm white wire to CH1 and the cool white wire to CH2.
  4. Set DMX Address: Use the buttons next to the digital display to set the desired starting DMX address. This decoder will occupy that address and the next one (e.g., if set to 001, it will use channels 1 and 2).
  5. Test System: Power on the system and use your DMX controller to test the dimming control for each of the two channels.
⚠ Precautions
  • Always match the power supply voltage (12V or 24V) to the operating voltage of your LED strips.
  • Do not exceed the maximum rated load of 10A per channel or 20A total for the decoder.
  • Ensure all wiring polarity is correct (+ to +, - to -) to prevent damage to the decoder and your lights.

Frequently Asked Questions

Q: What is the main difference between the D2-CX and other D-CX models?

A:The D2-CX is specifically a 2-channel decoder, making it ideal for CCT (tunable white) LED strips or two single-color zones. The D1-CX has one channel, while the D3-CX, D4-CX, and D5-CX have 3, 4, and 5 channels for RGB, RGBW, and RGBCCT strips respectively.

Q: What is RDM and how does it help?

A:RDM (Remote Device Management) allows a compatible DMX controller to discover, address, and configure the decoder remotely. This is a significant time-saver in large installations with many fixtures.

Q: Can I use this decoder for RGB LED strips?

A:No, this is a 2-channel decoder. For standard 3-color RGB strips, you need a 3-channel decoder like our D3-CX model.

Q: What kind of power supply is required?

A:You need a constant voltage DC12V or DC24V power supply. The voltage must match your LED strips, and the power supply's wattage must be at least 20% higher than the total wattage of your connected strips.

Q: How do I set the DMX address?

A:The DMX starting address is set easily using the buttons and digital display on the unit. This decoder will occupy the set address and the subsequent address for its two channels.

Q: Will this work with any brand of DMX512 controller?

A:Yes, this decoder adheres to the standard DMX512 protocol and is designed to be fully compatible with any standard DMX512 master controller, console, or software interface.
