DMX Data Distributor (English)

DMX
Distributor
Data buffer / isolator

The DMX Data Distributor, like the QBuffer, is probably the most state-of-the-art serial data distributor available. The unit provides 1kV isolation between the input and each of the four output sections. Each section is fitted with individually driven 3-pin and 5-pin XLR’s - providing at total of 8 buffered outputs.

All of the eight output lines are fitted with signal status indicators which will highlight a line fault at a glance.

DMX in and through lines are connected via USITT standard 5 pin XLR's. The through line may be terminated at the press of a button, should the unit be the last connection in the chain.

But what does it do and why do I need one?

Unlike analogue signals, DMX signal cannot be Y-split. If you want to split a DMX line, a Data Distributor is the answer.
Damaged or suspect cables can potentially do a lot of damage; even a routine thing like changing a fuse is a hassle when that fuse is several metres up in the air. 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.
