💡 DMX Overview – Understanding Channels and Values
Every DMX network has 512 channels. Each of these channels can carry a value between 0 and 255, which controls specific functions of your lighting devices—like brightness, color, or effects.
All your devices need to be placed within these 512 channels. How many channels a device uses depends on the model and its features. You can find this information in the device’s user manual.
📌 Example: Assigning a Start Address
Every DMX-compatible lighting fixture requires a specific number of channels to function. In this case, our fixture **uses 3 channels** to control different colors (Red, Yellow, Blue).
When we assign a start address of 10, the fixture **maps its channels relative to this address**:
- 🎨 Fixture Channel 1 → Assigned to **DMX Channel 10** → Controls the **Red** color
- 💛 Fixture Channel 2 → Assigned to **DMX Channel 11** → Controls the **Yellow** color
- 🔵 Fixture Channel 3 → Assigned to **DMX Channel 12** → Controls the **Blue** color
🔗 Using the Same Start Address for Multiple Fixtures
If we have **three identical lights**, we can set all of them to start address 10. This means they will all receive the same DMX data and will operate **synchronously**.
💡 Example: Assigning Different DMX Addresses
Now, let’s consider a different lighting fixture that requires **4 channels**:
- 🌓 Channel 1 → Dimmer function
- 🔴 Channel 2 → Red
- 🟡 Channel 3 → Yellow
- 🔵 Channel 4 → Blue
If we assign this light start address 10, we would create a **conflict**:
- 💡 Fixture 1 → Interprets **channel 10 as Red**
- 🚨 Fixture 2 → Interprets **channel 10 as the Dimmer function**
✅ Best Practice: Avoiding Channel Overlap
To avoid conflicts, we need to **carefully allocate DMX addresses**. Let’s say we have two different fixtures:
- 🎭 Fixture A: Requires **3 channels**
- 🎨 Fixture B: Requires **4 channels**
A correct setup would be:
- 💡 Fixture A → Start address **10** → Uses channels **10–12**
- 🚀 Fixture B → Start address **13** → Uses channels **13–16**
🎚️ DMX Fader & Color Control
In this image, you can see that:
- ✅ Channel 10 → **Highlighted in Red**
- ✅ Channel 11 → **Highlighted in Yellow**
- ✅ Channel 12 → **Highlighted in Blue**
Each **DMX channel** has values ranging from **0 to 255**:
- 🔽 **Slider at the bottom (Value = 0)** → The color **does not light up**
- 🔼 **Slider at the top (Value = 255)** → The color **is at full brightness**
This allows each channel to be **controlled individually**, making it possible to mix colors precisely.
📡 DMX Addressing Overview
Here is a simple overview of how devices are assigned addresses in a DMX network.
🔹 DMX provides **512 channels** for controlling your devices. 🔹 You decide which device gets which address. 🔹 All your devices must fit within these **512 channels** in your DMX setup.
If you have **more devices than available addresses**, don’t worry! I will explain how to handle that in a later section.
🎛️ **Setting the DMX Address**: The address must be set directly on the device. If you are unsure how to do this, check the **user manual** of your DMX device.
⚠️ **Make sure your device is in DMX mode!** Many devices have different operating modes. Some can work **without DMX**, reacting to sound (e.g., changing colors to the beat of the music). You can find out how to switch to DMX mode in your device’s **user manual**.
🎛️ Proper setup ensures your devices work correctly in the DMX network.
🔌 DMX Wiring: How to Connect Your Lighting Equipment
Now that we have answered the first questions, let’s take a closer look at DMX wiring and connections.
📌 Important to know:
Art-Net is transmitted over network cables (Ethernet),
but don’t worry—I will explain that later, once you understand the
classic DMX wiring.
🎛️ Connecting Your DMX Devices
The connection starts at the DMX controller. We will use the free and open-source software QLC+, which you can download here: 🔗 Download QLC+.
DMX works by daisy-chaining the devices. This means: You start from the controller and connect it to the first device. Each DMX device has both an input and an output.
📡 Step-by-Step DMX Connection
- 🔹 Step 1: Connect the DMX cable from the controller to the input of the first device.
- 🔹 Step 2: Take another DMX cable and connect it from the output of the first device to the input of the next device.
- 🔹 Step 3: Repeat this process for all your devices in the chain.
✅ This method ensures a stable and structured DMX signal flow through all devices.
🔌 XLR Connectors in DMX
The 5-pin XLR was originally designed for DMX. However, only 3 of the 5 pins are actually used. Because of cost reasons, many manufacturers switched to the 3-pin XLR.
📌 Today, both types are widely used. If your equipment has different connectors, you can use an XLR adapter:
- 🔄 5-pin to 3-pin adapter
- 🔄 3-pin to 5-pin adapter
✅ Both types work perfectly fine in DMX setups.
🛠️ DIY XLR Cables – Pin Layout
You can also make your own cables. Make sure to follow the correct **pin layout**:
- 🔹 Signal - → Connects to Signal -
- 🔹 Signal + → Connects to Signal +
- 🔹 Shield → Connects to Shield
❌ Do NOT cross wires or use unused pins! Incorrect wiring can cause communication errors in your DMX setup.

🌐 Simple DMX Network – Understanding Universes
If all your devices fit within the **512 available DMX channels**, they belong to the same **universe**. In DMX terminology, each separate network of **512 channels** is called a universe.
📌 What if you have too many devices? If your devices exceed **512 channels**, you need a second DMX output. Devices connected to this output will be in **Universe 2**.
This concept becomes very important when using **Art-Net**, because it allows you to manage multiple **universes** efficiently.
⚠️ Important Note About DMX Universes
DMX universes start counting from 0: - Your first DMX network is called **Universe 0**. - If you add another, it becomes **Universe 1**, and so on.
🚀 This is just a small introduction to **Art-Net**— more details will follow later!
🎥 Controlling DMX Devices with QLC+
I found a great video that explains how to control **DMX devices using QLC+**. Since this video covers the topic well, I won’t go into detail on how to set up devices in QLC+ here.
📺 Watch the video below for a step-by-step guide:
🛠️ Setting Up QLC+ with a USB-DMX Adapter
Despite the video, I still want to explain the **setup process** in my own words. Follow these steps to get started with **QLC+ and a USB-DMX adapter**:
- 🔌 **Connect your USB-DMX adapter** to your PC.
- 🖥️ **Open QLC+** and select your **USB-DMX adapter** as the **output device**.
- 🎛️ **Add your DMX device(s)** under the Fixtures tab.
- 📂 **Choose a fixture template**:
- QLC+ already includes many pre-configured devices.
- If your device is not listed, select **Generic** as a fallback.
- 🔢 **Set the correct start address**:
- The **start address of the device** must match the **address in QLC+**.
- For example, if your device starts at 10, enter 10 in QLC+.
- 📊 **Configure the DMX channels**:
- If your device uses 4 channels, set **4 channels** in QLC+.
- This ensures the correct control of all device functions.
✅ Once everything is set up correctly, you can **control your DMX devices** directly from QLC+.
🚀 Getting Started with Art-Net
Now that you are familiar with a **basic DMX network**, we can take the next step and explore **Art-Net**.
❓ Why Use Art-Net?
**Art-Net** offers two major advantages over traditional DMX connections:
1️⃣ Multiple Universes
- As mentioned earlier, a **DMX network** with **512 channels** is called a universe.
- If you have more devices than available DMX channels, you need to use **multiple universes**.
- Art-Net allows you to control **multiple DMX universes** easily.
2️⃣ Network-Based Data Transmission
- In a **traditional DMX setup**, the signal is sent from the **DMX output** of your controller.
- With **Art-Net**, the DMX signal is transmitted via a **network cable (RJ45 port)**.
- This allows you to use **network switches, fiber optic connections, and standard networking equipment**, just like in a normal computer network.
- The result: More flexibility and easier expansion of your lighting setup!
💡 Example: When Do You Need Art-Net?
Imagine you need more than **512 DMX channels** for your lighting setup.
🔌 Traditional DMX Setup
In a standard DMX setup, you would need **multiple DMX output adapters** connected to your controller:
- 🎛️ Devices in Universe 0 are connected to DMX Adapter A.
- 🎛️ Devices that don’t fit in Universe 0 are connected to DMX Adapter B.
🌐 Art-Net Setup
Instead of using multiple DMX adapters, **Art-Net** allows all DMX data to be transmitted over a **single network cable**! This simplifies the setup and provides much greater scalability.
🚀 This is just the beginning! In the next section, we will explore how to set up **Art-Net** step by step.
🌐 Why Art-Net Makes Sense When Using Software Like QLC+
Using Art-Net makes the most sense when your controller is a **software-based solution**. I personally use QLC+ as my DMX controller.
In QLC+, you can easily assign your devices to the correct universe. Each universe is linked to the network interface used for the Art-Net connection.
I assign IP addresses manually to all my Art-Net devices within a custom network range. For example, I use the range: 10.10.80.0/24.
💡 Direct Art-Net Device Connection
Some DMX devices already come with a built-in network port. In this case, you simply connect the network cable (carrying the Art-Net signal) directly to the device.
Inside the device's menu (e.g., a moving head or DMX LED), you need to set the correct universe and start address.
🔧 For example: If in QLC+ your device is assigned to Universe 1 with Start Address 100, then you must also configure the **same settings** in the device menu.
🔁 Using an Art-Net Gateway
Another common method is to use an Art-Net Gateway. In this case, the Art-Net signal is sent via network cable to the gateway.
Most gateways have multiple DMX output ports. You can configure which universe is assigned to which port— either through a built-in screen or a web interface.
🧠 Example: If the gateway receives Universes 0 to 3, you can set:
- 🔹 Port 1 → Universe 0
- 🔹 Port 2 → Universe 1
- 🔹 Port 3 → Universe 2
- 🔹 Port 4 → Universe 3
You can now connect your DMX devices to the gateway’s output ports using standard XLR cables, just like in a traditional DMX setup.
✅ Whether you connect directly via network or use a gateway—Art-Net gives you flexibility and scalability far beyond traditional DMX setups!
