Brauche Hilfe bei Störsignale in DMX Kette oder ähnliches

Post by Nik2020 »

Hallo,
ich habe ein DMX Interface von Showtec (baugleich mit Enttec DMX Pro) und betreibe es mit dem freestyler x2 (=2.0), habe bereits mehrere PAR Strahler/Moving heads nacheinander angeschlossen und jedes Mal ist für wenige das DMX Signal unterbrochen und es kommt kein DMX Signal mehr an (sieht man daran, dass das Gerät (egal welches) aus dem DMX Modus springt. Wenn das Signal dann da ist gibt es öfters Störsignale. Ich benutze nur kurze Kabelstrecken, einen Endwiederstand und ALLE Geräte funktionieren einwandfrei mit einem DMX 512 Controller (Mischpult). Nun die Frage woran das liegen könnte?
Danke bereits für mögliche Lösungen und Antworten!

What is the total length of your DMX cables?
Are you using 110 ohm impedance cables?
Does it work with one/any fixture connected using a short cable?

The problem you describe is almost always caused by cabling issues or a bad refreshrate setting in FreeStyler.

With cabling issues it is possible that it works with one device and doesn't work with another device.

Try to build up your DMX chain piece by piece, cable by cable. For each item you add, you test your chain.
When the problem starts to present itself, swap the cables one by one until the problem goes away.
This test might point you to a bad cable (bad connection) or maybe even a faulty fixture.
