The Lighting Controller

Hi group
I'm rather new at this. I have 4 Chauvet FXPar 9 ver 1 fixtures. I'm using ShowXpress sw on Windows 11 and a Feenteak cable USB to DMX interface.
When I select 6, 9 or 23 channels on the fixture the address selection starts flashing. If I select an address number and press enter on the fixture nothing changes, still flashing.
When I create something on ShowXpress, the fixture doesnt react.
My first thought is that I'm not specifying a channel on the fixture properly.
Possibly I have a defective cable interface?
I've tried 2 different PCs. One with windows 10 and one with windows 11.
Sorry if I'm posting in the wrong place.
Thanx in advance....

......am i the only one that ever had this issue?

Pretty sure that showxpress only works with Xpress boxes and not a ramdom usb dongle xd

Correct.

Okay, thanx, that's good to know. Can I assume that the blinking address # on the fixture would stop when I made a selection and was using a proper interface?
Is there an economical version of of one of these interfaces?
Would this be compatible?

economic = hardware only (no software, no technical support, no free DMX fixture libraries, ...)

Our DMX interfaces are here: https://thelightingcontroller.com/viewt ... t=5#p26389

Ok, it appears that the only way I can connect these fixtures to my pc is with a $300-$400 interface module.
