PSU? If not, I would be willing to bet that is your problem. In order to keep the voltage up in the line you need to always have a return run from the last scroller back to the PSU.
Out of curiosity, how long are your cable runs, and where is the PSU in relation to the scrollers?
return? You have to make a complete loop otherwise you can have serious problems. The return loop keeps the voltage level constant across all of the scrollers and prevents a voltage drop. Voltage drops are the main cause of what you are experiencing. We use 12 Scrollers at my college on the 400w PSU with no issues so the problem is most likely NOT the PSU if you aren't using the return loop. If you are using the return loop then it probably is the PSU.
Yes, it sounds as though there is no return line from the last scroller to the PSU. You may be dropping power by not having the return line connected.....
PSU...just for troubleshooting purposes, I would change it out and see if the problem follows.
If possible, could you please call me at Apollo @ (800)288-4626 so I may assist in finding the solution to this issue? I'd really like to help you, and while typing is alot of fun- conversation is always a bit better.
I had a similar issue with my forerunners awhile back and it turned out to be a broken pin in my cable.
