Hello Steve,

On the return path with termination built into the power supply, perhaps I am thinking of the Chroma Q rather than the Wybron stuff. I thought the Wybron equipment followed the same practice, but I don't have it in front of me and you do.

If the scrollers are simply daisy chained with no return path or built-in termination, the 4 pin terminators are definitely a good idea. This would relate to the requirements of EIA-485 as much as DMX512.

Water + RDM = poor performance. Water + DMX512 = poor performance masked over by lots of redundant updates of the information. Is DMX more robust? Technically, no, you just can't detect the problems as easily giving the perception that the DMX signal is error free.
