Hello,

I’d like to ask for some advice about what I might be doing wrong.

I need the cues in Playback 01 on the CueCore 3 to change depending on whether there is a DMX signal present on Port A or not.

I configured Port A as an input and Port B as Universe 1 output. In ShowControl, I then created the action DMX INPUT → RECEIVING → START and assigned it to Playback 01 Cue 01. I also created a second action DMX INPUT → RECEIVING → STOP and assigned it to Playback 01 Cue 02.

Unfortunately, this setup does not work and the playbacks do not change when the DMX signal is connected or disconnected. On the monitor, I can see the correct DMX input values that I am sending, but in the HOME tab, DMX A shows “NO”.

Do you have any advice on what I might be missing? I tried several dmx sources

Thank you very much.

Hello,

We tested exactly the setup you described here and can confirm that this is actually possible on the CueCore3  :D

On our side we configured:

- Port A as DMX input
- Port B as DMX output


Then in the Actionlist we used DMX input these actions:

- DMX → Receiving → START → Playback →Jump →Playback 1 →Cue 1
- DMX → Receiving → STOP →  Playback →Jump →Playback 1 →Cue 2


Every time we disconnected the DMX input cable, the playback changed correctly between Cue 1 and Cue 2.

We tested this on the latest stable firmware version 1.32.80.

Also, on our setup the HOME page correctly changes between YES and NO for DMX receiving status depending on whether the DMX cable is connected or disconnected. Since your HOME page still shows NO, even while seeing values in the monitor, I would recommend checking the DMX source itself and verifying that it is outputting a proper continuous DMX signal.

Here is attached the backup showfile we used for testing, so you can load it directly on your setup and compare the behaviour. The file is compressed as zip file that inlcudes the .tar file, so you first need to uncompress it and place the backup file inside the correct backup directory. After that, VManager should be able to retrieve and restore the showfile to your CueCore3.

If it is still not working on your side, please send us your backup showfile and we will be happy to investigate further.

Hope this helps!

Thank you so much for support Jorge, well the problem was that i was not on latest firmware, sorry for wasting yout time, next time i will double check.
Because I need to detect incoming DMX for switching between two 0–10 V control sources, it will probably be better to use the IO CORE 2, which also has a DMX INPUT and a DMX receiving action, and use the relay contacts to switch an external DPDT relay. Thanks for such a quick response :-)
