scjb

Don't use the RTL's too much myself, but I believe there can be some temperature drift as the oscillator warms up, so worth letting them settle down (in a stable environment!) before setting the offset. Example linky, many more knocking around. I seem to recall one chap even immersing his set-up in an oil-bath to keep the temperature as constant as possible... ETA: didn't see the previous replies before making this one. Apologies if redundant.

Thoughts with those affected. As Gareth says, waiting game to find out what happened.

Universal Guest Luminaire Interface , UGLI... Ah that was it. UGLIs and PIGLIs and Wynne-Boxes... oh my!

I loved it, thought it was a great system. Jolly bright. Near enough. The FOH rack would take in data from the desk on a SCSI line, do its magic and then throw it out down multicores (one data-pair per fixture, 30 fixtures per multicore) which was combined with power at the mains distro racks in dimmerworld. Output from the mains distro racks was via Litton multis, each supplying six fixtures via a trussmount splitter box. In the case of Washlights, the dimmed feed was also sent to the trussmount splitter boxes via Socapex, and then sent down the same 8-pole Speakon. As well as the main console (which had a couple of internal hardware revisions) there was also a Mini-Icon console that plugged into your Apple Powerbook, often used as a backup. There were also fudge boxes to allow control of non-Icon fixtures from the desk, and I seem to remember that due to a patent argument (with VL), the running of more than one non-Icon\VL S300 fixture on a DMX data-line was not sanctioned... Don't ask! And then there was the Icon-M (Medusa)... so near and yet so far...
