If you have more than 32 devices on your DMX cable, you need to provide a Splitter/Buffer to maintain the DMX signal quality. This 4 Way Optically Isolated DMX splitter/buffer will allow a total 128 down stream devices to be connected, 32 on each output. The DMX-SPLIT4 can be cascaded for even more devices up to 512. Single 9v-12v DC power supply required.Introduction The DMX-SPLIT4 module is 4-way DMX splitter, also sometimes known as a buffer or amplifier. Cased in a sturdy steel box, the splitter can be easily mounted on the rigging truss with plastic cable ties. Features Fully compliant with the latest USITT DMX512-A standard. Backwards compatible with the older USITT DMX512/1990 standard. Optically isolated input, with on-board isolated power supply. Four individually buffered outputs with common ground.
