I ordered a DMX Tabletop Controller and am looking forward to using it to control a follow spot that I managed to put together. One reason that I bought this model was the feature listed in the description, "9-pin RS-232 trackball connector port". However, I pulled down the manual and I see no reference to using the RS-232 port with a trackball. Where can I get information on attaching my trackball and mapping to a DMX address?
