Uni-Check

Description

Identify which universe an unknown cable carries.

• Instant universe ID — Broadcasts a unique 8-bit “ID value” on a single DMX channel for a range of universes. Plug a DMX viewer (e.g., DMXcat) into the cable: the value you read equals the universe number. No guessing, no scrolling through test pages.
• Zero patch changes — Sends test output without touching your patch, presets, or sequences. Safe to run anytime.
• Fast range targeting — Limit the check to a range (e.g., 9–24) to stay focused on the part of your network that matters.
• Saved settings — All settings used will be saved for fast access and release.
• Road-ready — Perfect when someone has messed up the connections, find out what cable carries which universe at the cable end of things.
• Companion tool — “Uni-Check – PatchScanner” lists which universes are patched in your show file.
  

What’s included

• Uni-Check
  Generator tool that transmits a universe-coded value on a chosen DMX channel across all selected universes simultaneously. 
• Uni-Check — PatchScanner
  Reporter tool that scans your show file and prints which universes are patched.

Manual

Uni-Check (generator)

User inputs

• Universe Range (start thru end)
  Enter a start and end universe (valid range 1–255).
  Example: 1 thru 64.
  
• Test Channel
  Choose which DMX channel carries the ID value (default ch: 512).
  
• Exclude Universe
  If you want to exclude one or more universes from testing for safety reasons (e.g., pyro at testing ch) (default: 0).

• Universe base
  Either use the Range specific above or use all patched universes, still respects excluded selection.
  
• Activate or Release
• Press Activate to write test values to universe selection
• Press Release to release values of universe selection
• Press Cancel to abort
  

Reading the result

• Connect a DMX viewer at the cable end.
  
• Look at the Test Channel you selected; the level shown equals the universe.
  
• Example: with Test Channel = 512, if the viewer shows value 11, the line is Universe 11.
  
  
  

Compatibility & notes

• Platform: grandMA3 (consoles & onPC).
  
• Tested on: v2.3.x and newer. Behavior is protocol-agnostic (physical DMX or network output like sACN/Art-Net).
  
• Universe cap: Because the ID uses an 8-bit DMX value, the tool intentionally excludes universes above 255.
  
• Viewer: Works with any DMX viewer that can display a specific channel value (DMXcat, node monitors, tester apps, etc.).
  
• Network mapping: If your node remaps universes (e.g., MA3 Universe 1 → sACN 101, Artnet 0=1), read the value with that mapping in mind.
  
• Show safety: Make sure you don´t have anything patched at the test-channel before testing.
