I think theoretically, but question would be how you get DMX into the PC. It might be possible to duplicate an output on ethernet and use ACDI to read this and send to Vis. Can't say for sure though.
Why do you need this? Is it to get it on a separate display?
I used the inbuild Visualizer, but that slow down my Console. Maybe its better now in V1.1, i will get the CD next Time. The old style with RS232 always worked fine.
I have never had any problem with the console slowing with Vis in any build, but I have read reports of this from other users. I believe the solution may have been a new driver file of some sort. I recommend emailing software.
