Whirlwind's CatdusaDMX is a 4-channel breakout box that uses 5-Pin XLR connectors to provide a dedicated way to use their Cat5 or even Cat6 Ethernet cable to transmit DMX lighting control. All you have to do is connect two Catdusa DMX boxes onto each end of an RJ45 cable and then you'll be able to use 5-Pin DMX cables to connect all of your equipment. Each box has two RJ45 connectors for easy daisy chaining, so you have access to connections wherever you need them! Each circuit has both male and female XLR connectors to allow for easy bi-directional signal configurations.
