DMX512 LED Strip Installation Guide: Setting Up MADRIX NEO & Wiring Your Strip

Part 1: Software Setup — Installing MADRIX on Your PC

Before touching any wires, you need to set up the control software on your computer.

Step A: Install MADRIX NEO Software

If you haven’t already, download and install the MADRIX NEO​ software on your PC.

💡 The installation process is the same as any other Windows program. Simply follow the on-screen prompts and read each page carefully​ before clicking Next.

• Run the installer

• Accept the license agreement

• Choose your installation directory

• Click Install​ and wait for completion

Step B: Connect the MADRIX NEO Interface

Once the software installation is finished:

1. Connect the MADRIX NEO interface​ to a free USB port on your PC

2. Locate the MADRIX program​ on your computer and open it

3. The software should detect the NEO interface automatically

✅ If everything is working, you’ll see the interface status as “Connected” in the MADRIX window.

Step C: Familiarize Yourself with the MADRIX Interface

Take a moment to look around the MADRIX software window. The layout may seem busy at first, but the key controls are logically placed. Don’t worry about mastering everything at once — we’ll configure just what you need for a basic LED strip.

Step D: Open Matrix Builder (Preferences)

1. Click the Preferences​ tab — you’ll find it at the top of the program

2. Click Matrix Generator​ — a new window will open

3. Under the Placement​ text field, you’ll see the Count XYZ​ section with three axes

Step E: Set the Axis Values

In the Placement​ section:

📌 This tells MADRIX you have a single line of 120 RGB pixels — perfect for a standard DMX512 LED strip layout.

Step F: Configure the Fixture Type

Above the Placement​ section, you’ll see the word Fixture.

1. Set your fixture to “Generic RGB 1 Pixel”

2. Click Apply

3. Click OK

🎉 That’s it! Your DMX RGB LED strip is now mapped and ready for control inside MADRIX NEO. Not too hard, right?

Part 2: Physical Wiring — Connecting Power & Data

Now for the hands-on part. Always prioritize safety — make sure no power is running​ while you work.

Step A: Prepare the Power Cable

1. Cut the connector​ off the end of the power cable to expose the copper wires

2. ⚠️ Be careful not to cut the part that connects to the power socket/outlet

3. Identify the wire with white text/marking​ on the power cable — this is your positive lead (+)

4. Mark it clearly so you don’t mix it up

⚡ Double-check: No power should be connected while you strip wires.

Step B: Connect Power to the LED Strip

Each end of your DMX LED strip needs power:

🔧 Make sure each end of the strip has a power connection.​ For longer runs, inject power at both ends (or at intervals) to prevent voltage drop.

Step C: Connect DMX Data (NEO → LED Strip)

1. Take a 3-pin to 5-pin DMX adapter​ (or the correct adapter for your strip)

2. Connect it to the DMX output​ of the MADRIX NEO interface

3. Connect the other end to the DMX data input​ of your DMX512 LED strip

📌 Remember: DMX carries data only, not power. The strip must have its own 24V power supply connected separately.

Step D: Power On & Test

1. ✅ Verify all connections are secure

2. ✅ Confirm correct polarity (red to positive, black to negative)

3. ✅ Confirm DMX data is connected to the correct pins

4. Switch on the power supply

Your DMX RGB LED strip should now light up and respond to MADRIX NEO software controls.
