    No. Usually dmx pin 1 (dmx 0v or dmx gnd) should be common to the power supply 0v.

    Aha!

    Well. Is the 5v psu part of the fixture? I was assuming it was. I've converted all my lights this way.

    If not, you'll need to connect xlr pin 1 to your psu 0v because otherwise there'll be no reference for the dmx.

    No, this is transmitter side with external wall-psu. My DMX-controller is connected to laptop via USB. Just tested won't work with wall-psu negative connected to PIN1 on XLR OUT.

    I think its better someone to draw real connections so anyone can see. Something like my picture above. Please draw transmitter side and receiver side. Thanks.

    Should user connect hardwired from USB-DMX-box to first ficture and from there continue via wireless DMX?

    Well, this connection (blue line) did not help on transmitter side in this case (USB-DMX-box)...

    Ok, I figured it out!

    On transmitter side, DMX pin1 must be connected to fixtures PSU negative as it usually is.

    On receiver side it doesn't matter.

    For the avoidance of doubt, don't call 0V negative (because it isn't!)

    Also, you realise that you can power your wireless DMX transmitter from USB don't you? I have my wireless DMX in the same box as my USB DMX adapter & it doesn't need an external PSU.

    Well I have been told from school days that in DC side there is positive and negative.

    I have to check that USB powering, maby i can build it inside my USB-DMX box!

    + is positive with respect to 0v. Negative would be er.. negative with respect to 0v. In split rail supplies, you can have +5, 0 and -5V for example. 0V in that case really shouldn't be called negative

    Semantics!

Size:  82.8 KBI made these boxes for people who didnt want to open up the lights. Piggybacks on the IEC for power, and sticks on the back of the fixture. Not as cheap as a dongle, but doesn't need charged or a silly 5v psu lead.
