Flx S48 7.9.7
I sometimes had freezes of a few seconds, no dmx signal out, probably due to electrical interference. I solved it with the cat6 cable shielded between console and router.
Sometimes there have been long freezes of the control panel after the connection of some high absorption usb peripherals (usb lamp etc.), no dmx signal out. When it is freezes no physical button works, only the touchscreen, remote control and external keyboard reacts.
I would have liked more isolation between the heart of the console and the outside world.
Hope this helps
