Study Notes
DMX Controller Overview
- A DMX Controller enables efficient management of lighting equipment and other compatible devices.
- Allows pre-programming of lighting effects and real-time control during performances.
- Functions include enabling strobe lighting, color changes, and dimming features.
DMX Protocol
- Operates through a unidirectional signal from the Controller to lighting fixtures.
- Compatible devices use pre-installed modes for synchronization in groups.
DMX Fixtures and Channels
- DMX fixtures are individual lights or groups assigned to specific channels or modes.
- The DMX Universe consists of 512 channels, each controlling different parameters like color or strobing.
- Each channel has data values from 0 to 255, determining the intensity of the parameters.
DMX Personality
- Refers to the specific set of parameters assigned to a channel for controlling a fixture.
DMX Scenes and Chases
- Scenes are saved settings on the DMX Controller allowing for easy repetition of effects.
- DMX Chases are sequences of chosen and played Scenes for dynamic lighting arrangements.
Setting Up a DMX Controller
- Identify the starting address for fixture assignment, remembering the example of a standard DMX Controller with 16 channels.
- Each fixture typically uses sequential channels (e.g., Fixture 1: channels 1-16, Fixture 2: channels 17-32).
Steps to Set Up DMX Addresses
- User Manual: Check for the number of channels on your specific DMX Controller.
- DMX Mode: Ensure fixtures are set to DMX mode, which may switch automatically with signal detection.
- Assign Addresses: Avoid overlap in channel assignments; use modern controllers with screens or manual dip switches for older models.
- Save Addresses: Save assigned addresses for fixtures using corresponding buttons on the Controller.
Signal Management
- Prevent DMX signal bounce back by connecting a DMX terminator to the last fixture's output to avoid interference.
Reference Sheets
- Create a channel reference sheet for managing the 512 DMX channels, marking fixtures and assignments for easy tracking.
- Downloadable reference sheets are available for convenience.
Using the DMX Controller
- For individual lights, select the appropriate mode and starting address for each light.
- For group control, assign multiple fixtures to the same starting address, providing simultaneous effects.
Advanced DMX Interfaces
- Modern DMX Controllers support connections with laptops, tablets, and smartphones.
- Features include downloadable fixture profiles, automatic addressing, and keyboard controls to enhance user experience.
