Hi there,

I'm an electronics device developer. I'm testing my new hardware design for an Art-Net Node and trying it with different controller software. In this case, I configured QLC+ to send data to my Art-Net device, but I got a warning of my device running out of internal storing buffers. This was due to QLC+ sending full Art-Net frames every 20mS, wich gives 50 frames per second. And that value is out of specs in Art-Net to DMX512 conversion, because DMX512 can only send around 44 frames per seconds, so my internal device is receiving more info it can deliver on time over DMX512 physical layer, until running out of buffers (and then, discarding some of them to make room).

So, is there a way to change the Art-Net fps refresh rate?

Thanks!

ArtNet output is synchronous with QLC+ master timer (i.e. there's no separate thread for ArtNet output). The same is tru for e1.31 plugin.

Howto to change master timer frequency: http://www.qlcplus.org/docs/parameterst ... asterTimer (section 4.5).
