All of the eight output lines are fitted with signal status indicators which will highlight a line fault at a glance. The through line may be terminated at the press of a button, should the unit be the last connection in the chain. Unlike analogue signals, DMX signal cannot be Y-split. If you want to split a DMX line, a Data Distributor is the answer. A thoughtfully-placed Data Distributor is the answer.
Earth loops are a common problem.
Once again, because the DMX input and output are isolated from each other in the unit, earth loops cannot occur. Getting the pin-outs wrong when soldering a plug to a cable will result in overloading and signal reflection. Such a problem can't get past a DMX Distributor and is therefore localised. Should you happen to be lighting something the size of a football stadium, the unit will amplify the DMX signal, ensuring that the last device in the chain is as responsive as the first.
