USB – POWER
The interface features a USB Type-B port and a 2.1 mm, 12 V, 1 A external power input, plus USB power, status, and external power LED indicators.
DMX Ports
The unit features 2 Neutrik XLR3 ports carrying two DMX universes (1024 channels total).
System Protection
What sets our equipment apart?
Opto-Isolated DMX Signal on Every Channel
Optocouplers create an optical barrier between each output channel and the interface control circuit. This electrically isolates both stages and protects them from electrical issues such as voltage spikes.
ESD Filters on DMX Inputs and Outputs
ESD filters help prevent unexpected behavior, malfunctions, and damage caused by electrostatic discharge, ensuring stable and reliable operation.
DMX Stage Voltage Isolated by External Power
In addition to optical isolation, complete output-stage protection requires separating the input and output power supplies. This is achieved with the external power supply.
EMI Filters on DMX Inputs and Outputs
EMI filters help prevent malfunctions and damage caused by electromagnetic interference, ensuring nearby equipment does not affect normal device operation.
