DMX to USB cable issues

Hi, I have the DSD TECH USB to DMX Interface Cable with FTDI Chip and have the D2XX drivers installed. I tested the cable and lights in QLC+ and it works fine but not in VSL Live (1.4.50.868) - I get nothing happening - no pan/tilt, no colors. I read somewhere else on here that this chipset is compatible but not sure what I’m doing wrong.

Hi @VisionsOfMorpheus,

which version of VST Live are you running? And what is not working?

Thank you,
Michael.

I have updated my question with the answers.

… thank you for updating your answer. Did you configured the DMX track correctly? Here are some steps

  1. Start VL, New Project
  2. Select TRACKS
  3. Add a DMX Track
  4. In the Inspector of the Track (left side) you can select an Input : Select DMX Mixer In
  5. Open the virtual DMX Mixer with the “|->” Button

  1. Now select your Output “DSD TECH USB to DMX Interface Cable”. Does it have a name?
  2. Now activate the Monitor control (the orange one)

Now you should be able to control your DMX hardware with the virtual DMX Mixer.

Better?

Ok I tried all that but no difference. My light doesn’t respond. I have universe set to 0 in this one light test set up, with the light in 14ch mode on channel 1. I don’t have an input mixer (hardware or anything either). I have the virtual DMX mixer panel open and controlling channel one and I can see it change in the visualizer if I select that as an output. My DMX cable shows as FT232R USB UART Out. I am on Win 11 Home.

… can you point me to an online store where I can buy your device?

Thank you,
Michael.

Hi, just thought i would jump in here . I too am having the same problem as VisionsOfMorpheus. I bought this DMX Cable from an online auction website, here is the link to it.

USB To DMX Interface Adapter LED DMX512 Computer PC Stage Lighting3
The DMX works flawless on versions up to but NOT including VSL Live (1.4.50.868).
I am using a 7 channel Led par light and all works as it should eg, ch1 master fader, ch 2 red, and so on. Also works exactly the same in Freestyler.
But any version i have tried after 1.4.50 does not work at all. I have tried everything even up to VSTL Pro 2, v2.10 but to no avail, until i go back to 1…4.2 then all is working again. I have the nescssary D2XX drivers installed correctly from the FTDI website i am really wanting to continue to use the DMX feature of VSTL but i am unable up to present. Thanks.

… we’ll check!

Michael.

Mine just arived and i can confirm, works perfectly on freestyler, while on vstlive i can select it in dmx connections, led on the usb dongle shows continuous tx, but fixtures show “add001 no dmx signal”. And that’s all, moving mixer channels while monitoring, no movements or color changes.

Regards, Ciro.

@Spork i can confirm DSD tech cable i just bought works until 1.4.8 included. 1.4.9 not working but fixture see dmx signal. 1.4.50 same, not working but fixture see dmx signal. In 2.0.14 dmx fixture says NO DMX signal at all.

Hope it helps. Ciao! Ciro.

@Spork , just tested on 2.0.15 , no luck… ! Lights still show “No DMX signal” (confirmed still working on 1.4.8)

Ciao, Ciro.

Hi Ciro,
I had a similar problem with an enttec USB to DMX adaptor and @JOHANSSON_MATT mentioned changing the receive channels on the fixtures up by 5 channels, so if you send from Freestyler to fixture 1 on channel 5, set the fixture to receive on CH 10 when using VST Live.
It may not work but you won’t know till you try, and if it does then it might help us find a more permanent fix for the DMX issues.

Thanks but it’s different.

This cable don’t send dmx signal at all (while it was working regularly in 1.4.8). Tried up to ch 32 (13 channels fixture), fixture shows on its screen “no dmx signal”. Close 2.0.15, open 1.4.8 and bum, fixture shows dmx signal and go in working position (pan/tilt on 0-0), faders 1-13 from virtual mixer can control the fixture real time regularly.

Ciao, Ciro.

Hi @ciro1983811

I’ve ordered this cable and I can work with it with 2.0.15. So I guess there is something which I don’t understand.

… can you please give me more details with that? You can select the cable as an Output with a DMX Track. And then? You have a DMX Track with same DMX Events. You are starting the Transport and the cable receives events and lights up? The cable itself (well, my one) has a small light bulb. Your one, too?

Every detail helps,
Michael.

… that has been fixed with 2.0.15,
Michael.

@Spork hi, yes i can select the cable as an output and the led on the cable flashes as tx, but no signal arrive at the fixture. I even disinstalled all the drivers and reinstalled ftdi 2xx from the ftdi.com site.
I uploaded a short video comparing the behaviour on 1.4.8 vs 2.0.15.

Let me know if i can do anything to help you.

Ciao, Ciro.

… where is the video?

Michael.
