Dalicore DMX Loss Behavior: How to force 100% on signal loss?

[Tenchi]

Hello,

I have been using the Dalicore connected via a direct DMX line to my ChamSys QuickQ 30 for a while now. It works wonderfully to control, but unfortunately, I’m running into an issue regarding how the Dalicore behaves during a signal loss.

Whenever the DMX value is greater than 0, and I unplug the DMX cable from the lighting console or turn the console off, all DALI lights turn off! (The entire hall goes completely dark), regardless of whether they were running at 100% or 50%.

On the other hand, if the value is 0 (everything dark) and I unplug the DMX cable, all DALI lights turn on after about 3 seconds.

I have already tried everything possible in the settings (failure level to 254, power-on level to 254) and looked into the triggers as well.

During our theater performances, I’ve been working around this by unplugging the cable at the end of the show while the lights are still set to 0. However, there has to be a solution so that even if the lights are at 50% or 80%, a signal loss immediately causes them to go to 100%. (This is crucial, because in the event of a power outage during a show, all the lights need to jump back to 100% right away).

I have already studied the entire manual and couldn't find anything.

My DALI lights are divided into 4 groups, and I’ve assigned a DMX address to each group (this is necessary because our event hall is split into multiple zones).

Maybe someone here can help me out.

Kind regards

Hello Tenchi,

First of all thank you for raching out and using our products 

The DALI Power-on Level and Failure Level do not apply when the QuickQ’s DMX signal disappears. This needs to be handled in the DaliCore Show Control.

Create a DALI scene with all four groups at 100%, then trigger it using:


DMX Input → Receiving → Stop


This action will run when the DaliCore stops receiving DMX. The unusual inverted behaviour you currently see may mean there is already a scaled or inverted action configured, so please also send us a DaliCore backup from vManager and your firmware version so we can check it.

Please note that this only works while the DaliCore, DALI bus power supply and luminaires remain powered. It is a DMX-loss fallback, not a replacement for a certified emergency-lighting system.

Hope this helps!
