While it seems that the primary problem has been discussed and there are many solutions, I thought that I might just clarify a few things on the
scroller issue. Yes there were scrollers made that were powered with wall mains of 120 or 240 volt ac, depending on which side of the pond you reside. Wybrons very early model "the
Scroller" was mains powered and received
DMX with a standard 5 pin
XLR. I still see them on Ebay frequently, but having owned a few, they are very finicky about the
gel strings being cut and taped in the proper size and mounted perfectly. If they were not, they would hit the limit on the
feedback pot and then lock up and burn out the supply or the motor.
As for scrollers that run on 0-10 vdc (analog) the earliest models built by Camelont in Sweden, could be either
DMX or analog. In either case, they still required 24 DC on pins 1 and 4 with the signal on 1,2 and 3. There is a small
switch, that determines the signal protocall. These scrollers were sold under the name "Rainbow". The sme
scroller was also sold by
Strand as the "Colour
Call", only in this case they also had third protcall choice that was uniquely
Strand. These scrollers had 5 pin XLRs with the signal on 1,2 and 3 and the
power on 4&5. Kind of a unique idea so that you could use the original
DMX cable where all pins were supplied the length of the cable. This didn't last very long and most people changed the connectors to 4 pin and used along side the Rainbows. The company Spectrum Engineering, in Canada, either licensed or some similar arrangement with Camelont, and builds scrollers under several names such as CromaQ,
Apollo Spectra and Ranger. I believe but can not prove it, that they also
build the Morpheus. The very early "Rangers" were 0-10 analog.
While studying scrollers online, I found a document that stated the
scroller was first invented by a man in Dallas Texas, and that he used 0-10volt analog control.
Now some of this information I give as I have heard it, but I own
Strand Colour calls and rainbows and
Chroma Qs and the statements I have made about those are fact. I have remove the signal selector switches and jumpered them to run only on
DMX, so that none of the electricians in the
theatre can accidently set them to analog.
