DMX-WTR | DMX-WRE: How To Set Up & Use

Introduction

Wireless DMX technology eliminates the need for long cable runs between your DMX controller and lighting fixtures. With the Rockville DMX-WTR (transmitter) and DMX-WRE (receiver), you can easily control multiple lights wirelessly, improving flexibility and reducing setup time. This guide walks you through how to set up wireless DMX and integrate it into your lighting system.

What You Need

• Rockville DMX-WTR (Wireless DMX Transmitter)
• Rockville DMX-WRE (Wireless DMX Receiver)
• DMX Controller (e.g., Rockville Rockforce 384)
• DMX-Compatible Lights (e.g., Rockville RockPAR 50, BestPAR 60)
• Power source for non-battery-powered transmitters

Step-by-Step Setup

1. Understanding Wireless DMX

• Wireless DMX works by replacing traditional DMX cables with a wireless signal.
• A single DMX-WTR transmitter can communicate with up to 25 DMX-WRE receivers.
• Some lights come with built-in wireless DMX, while others require a wireless DMX receiver.

2. Connecting the Wireless DMX Receiver

1. Prepare the light
   • Set your light’s DMX address (e.g., 001 for first channel).
2. Power on the receiver
   • Locate the small white button on the receiver.
   • Use a pointed object (like a screwdriver) to press the button.
   • The LED indicator will turn on, displaying a color—this is crucial for pairing.
3. Plug the receiver into the light’s DMX input
   • Insert the DMX-WRE receiver into the DMX IN port of your light.

3. Setting Up the Wireless DMX Transmitter

1. Power on the transmitter
   • The DMX-WTR requires external power, so plug it into an outlet.
2. Connect to the DMX controller
   • Plug the DMX-WTR transmitter into the DMX output of your DMX controller.
3. Sync the transmitter to the receiver
   • Match the color of the LED light on the transmitter to the color of the receiver.
   • Once synced, the receiver’s LED will flash, indicating communication.

4. Testing the Connection

1. Control the light wirelessly
   • Adjust Channel 1 (Red), Channel 2 (Green), and Channel 3 (Blue) on your DMX controller.
   • The connected light should respond without needing a wired connection.
2. Add more lights
   • If your additional light has a built-in wireless DMX, match its color to the transmitter’s.
   • If the light does not have built-in wireless DMX, plug in another DMX-WRE receiver and sync it.
   • Once connected, moving the faders will control all linked lights simultaneously.

5. Expanding Your Wireless DMX Network

• You can connect up to 25 receivers to a single transmitter.
• Use Wireless DMX for:
  • Large venues (e.g., catering halls, event spaces)
  • Mobile DJs who need quick and clean setups
  • Stage productions requiring flexible light placements

Troubleshooting & FAQs

Q: My receiver is not connecting to the transmitter. What should I do?

A: Check that the LED colors match on both devices. If not, press the button on the receiver to cycle through colors until they match the transmitter.

Q: My lights are not responding to the controller.

A: Ensure that:

• The DMX addresses are set correctly.
• The receiver is plugged into the DMX input of the light.
• The controller is properly configured.

Q: Can I use multiple transmitters in one setup?

A: Yes, but each transmitter must be assigned a different color channel to avoid interference.

Conclusion

Wireless DMX technology is a hassle-free way to control multiple lights without dealing with cables. Whether you’re a mobile DJ, event planner, or lighting professional, the Rockville DMX-WTR and DMX-WRE provide a simple, effective way to expand and improve your lighting setup.
