Hi Simon,

Thanks for the post, unfortunately i have already done all of the above to no avail, dmx workshop sees the device and the artnet coming from it fine. But Catalyst, no dice, it does pop up briefly but no DMX is actually seen then it disappears forever.

I am just about to put together an Artnet Quartz patch to see if that work on the same system which should help narrow things down a little more.

Cheers

Gareth
