I've got a daisy chain of 14 Altman SpectraCyc 100s set up through 3 circuits (6, 6, & 2) set as non-dims (switched). Most of the time they're fine, but after a while (sometimes minutes, sometimes hours) one of them at random will start flickering a barrage of colors at full. When this happens, the display on the wigging out SS starts flying through cycles of single digit numbers (like the hundredths decimal on a countdown clock). It's never the same one and power cycling fixes it for the moment, but I'd like to have a more permanent solution. I would say I've got a bad cable or a bad unit, but for the fact that it's a different unit every time. Any ideas?
