ENTTEC D-Split (2x3, 2x5) DMX Splitter
Affordable and simple to use, the ENTTEC D-Split is a 4 port DMX splitter that allows you to easily expand your lighting rig. Choose between the model with 2x 3 Pin outputs and 2x 5 Pin outputs, or all 5 Pin outputs. We like the D-Split because it's really inexpensive, but the best quality "cheap" splitter we've ever seen!
From the Manufacturer:
The D-Split is an optically-isolated DMX splitter and repeater for DMX512. With one input and four outputs, the D-Split gives you the ultimate flexibility to link up to 32 DMX fixtures.
