UniverseIdentifierMA3

A small GrandMA3 plugin to write a visible universe identifier into the last DMX channels of every universe (channels 511/512).

🔧 What it does

• Writes an identifier to the last DMX channel(s) of each universe so you can read the universe number on a DMX tester/display.
• Supports 8‑bit (channel 512 only) and 16‑bit (channels 511+512) modes.
• Can release (turn off) the identifier channels.

🚀 Features

• Uses channels 511 (low byte) and 512 (high byte) by default
• Default universe range: 1–512
• Interactive menu with options: Cancel, Release, 16‑bit, 8‑bit

📦 Requirements

• GrandMA3 console/environment where plugins are supported
• Place the whole UniverseIdentifierMA3 folder into your gma3_library/datapools/plugins folder

🛠️ Installation

1. Copy the UniverseIdentifierMA3 folder into gma3_library/datapools/plugins.
2. Import the plugin into your showfile.
3. Run it.

▶️ Usage

• Run the plugin from the plugin pool/Make a macro. The menu lets you choose between:
  • 8‑Bit — writes only channel 512 with the value for the universe
  • 16‑Bit — writes channel 511 (low) and 512 (high) if you have an expensive rig.
  • Release — turns the identifier channels off

Tip: Always keep the identifier on while building the rig. Reserve 511 and 512 for this purpose only. Use a DMX tester with a display (DMXcat or similar) to read the universe identifiers.

⚠️ Notes & Safety

• The plugin iterates over the specified universe range and issues commands for every universe—use it carefully on live shows.
