Bottle Posted April 30, 2005 Share Posted April 30, 2005 Howdy to everyone in the Blue Room Have been programming up a new Zero88 Diablo desk (can do 18ch of Generics + up to 18 ML fixtures) Here's the issue-ette I've just come across. When programming in several MadFX Madscans, have found that there is considerable mirror and colour/gobo wheel jitter. I have tried changing DMX cables, different terminator, different order of connection, all to no avail, so I'm posting this query here in case someone has had a similar experience. Created a profile for the Madscan using the Zero88 Fixture Creator software. Now, I also have a MadMagician connected - this does not seem to have an issue. Obviously, it may be an issue with the Madscans receiving DMX, but I have had them running before with a Milford Instruments DMX sender and some PC software. Normally I run them using a MadFX controller. Oh, and I've already submitted a query into Zero88 - so we'll see if that bears any fruit. :unsure: Hope you guys (and gals) out there can help Cheers Ian S Link to comment Share on other sites More sharing options...
stevep Posted May 6, 2005 Share Posted May 6, 2005 :) Are all the madscans doing this or just the last one in the chain? At a guess this sounds a lot like the DMX signal bouncing back or being degraded - something thats in common discussion in the blue room, so obvious questions: have you placed a terminator on the last fixture? are you sure the cables are in good condition etc Link to comment Share on other sites More sharing options...
Bottle Posted May 6, 2005 Author Share Posted May 6, 2005 Thanks for the reply, SteveP The setup: Had a couple of scans set up on a T-bar with a short length of DMX cable between them, and a longer run to the desk. The last scan in the chain had a DMX terminator fitted - so not expecting any problems there. Both scans were misbehaving, and it made no difference when I swapped the cables around I.e: 1) Desk --> Scan1 --> Scan2 --> Terminator 2) Desk --> Scan2 --> Scan1 --> Terminator 3) Desk --> Scan1 --> Terminator 4) Desk --> Scan2 --> Terminator I tried different cables, terminators etc, in case it was an issue with my DIY cables. UPDATE: Got hold of a couple more MadScans + Magician - No Problems!!!!!! Must be the first two scans I got were fubar (seemed to work OK in Lightshow mode with the Raving Mad controller) Also got a response back from Zero88, and they couldn't shed any light on it (no pun intended!), so I'm probably looking at a pair of semi-duff scans (hope I can return them to MadFX for investigation/repair! :o ) Anyway, I've found a local place that sells second-hand/nearly-new scans, and I've seen another 4 MadScans + controller for less-than-stupid money, so I might give them a go this w/end :) .
