DMX512

Ein DMX-Bus zieht sich durch unsere Räume. Die daran angeschlossenen Geräte sind per Home Assistant und über die Taster am Eingang steuerbar.

Vorhandene Hardware

In Gebrauch

• Scheinwerfer: 22x Stairville LED PAR 64 10mm RGB silver
  • Bedienungsanleitung mit DMX-Kanalbelegung

• LED Bar: 1x Stairville LED Bar 252 DMX RGB
  • Bedienungsanleitung mit DMX-Kanalbelegung

• DMX Splitter: Stairville DMX Splitter 2
  • Durch Verwendung von 5pol-3pol-Adaptern können wir insgesamt 4 Zweige benutzen. Das sollte bei den kurzen Entfernungen keine Probleme machen.

• Terminator: 2x American DJ DMX terminal resistor
  • Im Grunde nur ein XLR-Stecker mit 110Ω Widerstand zwischen +/-

Nicht mehr in Gebrauch

• Controller: Stairville DMX-Master MK II ENC
  • Bedienungsanleitung
  • Reset-Anleitung

• Eurolite USB-DMX512-PRO Interface
  • Bedienungsanleitung
  • Open Lighting Architecture - Daemon und Library zur Ansteuerung

Kanalbelegung

Die Scanner-Tasten am Pult sind in einem 16-Kanal-Raster belegt.

Die Lichter im Vortragsbereich und im Gang zu den Werkstätten sind über die Taste 1, die Lichter im Hackcenter sind über die Taste 2 jeweils auf Kanal 1-7 steuerbar. Page Select drücken, um in die jeweils andere Gruppe zu wechseln.

Integration in Home Assistant

ESP8266 mit Grove-DMX512

Notiz zu Grove-DMX512: Bus-tranceiver wurde am 20.04.2023 ersetzt, ist jetzt ein MAX3485. In diesem Zuge wurde der ESP8266 auch zum Verteiler über dem Getränkeautomat bewegt um einen sauberen Systemaufbau zu erreichen und allen Geräten ein Störungsfreies Signal zur Verfügung zu stellen.

Die Scheinwerfer sind wie folgt im Home Assistant eingebunden:

Home Assistant -> ESPHome -> ESP8266 -> Grove-DMX512 -> Scheinwerfer
