Is there any hope of getting the Eurolite USB-DMX512 Pro working under windows.
It's quite frustrating to see
-- the lower end Eurolite USB-DMX512
-- AND the newer Eurolite USB-DMX512 Pro MkII
are working fine on windows with QLC+ :-(

I'm using freestyler so far but wanted to jump over to qlc+...

Steven complains that out of three Eurolite models, only the one he has doesn't work.

Eurolite sent me some adapters and I was able to test them on the supported OSes.
Unfortunately there is a Pro adapter on the market (which I don't have) that uses a different chipset and we haven't been able to figure out how to make it work on Windows.
Basically it suffers the same "code struggle" as the DMX4ALL nanoDMX (which I have)
I'll try again to see if I can make the nanoDMX to work in Windows and if I succeed, the Eurolite Pro should work as well.
However at the moment I don't really have time to look into this.

In the meantime I have purchased a Pro MKII.

But now I have the issue that with this adaptor, there is an incredible amount of slack on the signal.
Whatever I do in the qlc+ interface, even just an adjustment in the simple desk, takes between 0,5 and 3 seconds to be sent to DMX.

Also when monitoring the values in qlc+ you can see the delay also there.

I'm using the latest FTDI drivers 2.12.26

Has anyone seen this before?

USB-DMX512 PRO Interface MK2

DMX USB: FT232R USB UART - DMX 1 Mode Output: Pro Rx / Tx
With other modes, DMX signal is not output

I too have the same problem of excessive slowdown.
Practically it is useless.

Now use a DMXking ultraDMX RDM Pro, which runs at 100% without any problems.

Hi all,

For a special project we bought the "Eurolite USB-DMX512 Pro MK2" interface and are facing the same problems as you guys mentioned.

We already contacted the Eurolite distributor (Steinigke, as we are Eurolite dealer as well) and asked why these interfaces are not working like it should be.
Unfortunately they have no explanation why it's not working together with QLC+, so maybe it's not the interface but a bug in QLC+ ?

Problem description:
- Slow response DMX output signal
- Uncontrolled flickering lights when running a show, even a few seconds after stopping or activate black-out

Tested with:
- Windows 10 Pro x86 (32-Bit)
- QLC+ V_4.11.0
- Driver and the latest FTDI driver
- DMX output mode set on (Pro RX/ TX)

We also did a test with a DMXking ultraDMX Micro USB adapter, which is working 100% with no issue's at all.

Hopefully is Massimo or some else able to track down this strange problem.
And before I forgot, thanks Massimo for all your hard work to make QLC+ to a succes you are doing a great job!!!

Hello all!

Unfortunately I experienced the same problem. The output coming from the Eurolite USB-DMX512 Pro MK2 interface is very laggy and flickering. For our purposes it's practically unusable. I'm not quite thrilled about this, since I am now forced to buy a new interface (I'd rather buy a new interface than use another program 'cause your program is fantastic!), but

Please: Remove "Eurolite USB-DMX512 Pro MK2" from the "Supported Hardware" list on the website, as this interface is clearly not functioning with QLC+ (it works well with other DMX software), at least until these problems are fixed. I specifically bought this interface for usage with QLC+ after I decided that QLC+ is the software I want to use, and saying that it's supported by your software is very misleading.

Thank you very much! Your work is fantastic! :)

Best wishes
