It needs to be descriptive, but the shorter the better.
My DMX labels are all of the form UxCy Arch a-b or UxCy Mini tree 1 red where x = unit number, y = channel numbe, a = element number if more than 1 and b = segment # when more than 1.
For SS
I started wth Rick's Sequence builder tool. My labels look like "SSCx Roof Left Node_yyz" where x is the SSC # I have assigned and labeled on my pipe. yy=the channel # and z=the color R G or B. If it is a hybrid channel there is no z attribute. I would have left the word Node out, but it works fine.
