Splitters
Like most digital protocols DMX cannot be simply split by using multiple Y cords. It might work for a while but sooner or later (probably at the worst moment) the data will crash, therefore a data splitter is required.
XTBA has been building DMX splitters for over 20 years and they can be found hidden from view in thousands of venues quietly going about their appointed tasks. From fully opto-isolated and line protected, single isolation and splitters with displays to monitor data and line termination XTBA has a splitter for all occasions - all at 'popular prices'.
