Overview

The DMX250 is a transceiver designed for DMX/RDM network communication over the Power line. The device

operates at a speed of 250Kbit/s. It eliminates complex cabling and simplifies installation.

The DMX512 messages over the power line are error protected and modulated using narrow-band frequency. Up

to eight independent DMX/RDM networks can operate in parallel on the same power line using different

frequencies. A QFN32 5x5 mm package provides a small PCB footprint

A single capacitor couples the device to the DC power line. A simple high voltage interface (external) allows

operation over AC power lines.
