• Front power switch optional - select to have a power switch installed
• DMX input with 3 or 5 pin - provides DMX loop through for viewing and storing from any DMX source
• OPTICAL INPUT OPTION - In order to optically isolate the input and offer protection, the DSI-4 requires a 25mA input line load which is ½ of a DMX 512 daisy chain load. It is recommended this unit be used directly out of the lighting board or DMX generating device. Because of this load the input does not conform to the DMX 512 specifications but should work with most systems. Also note that the outputs are separately driven and electronically isolated, not optically isolated from each other.
• Equipped with 1 RS232 to DMX converter, add up to 4 for a total of 5 independent converters in a 1U enclosure 
• Equipped with a 3 pin XLR connectors, optionally add 5 pin XLR connectors to each converter
