What is it?

The DMX DC Powerline Modem makes it possible to transfer the DMX-frames throughout the DC power cables by means of Frequency Shift Keying (FSK) with a carrier frequency of 60 kHz and a transmission speed of 4800Bd. It avoids the need of separate wires. Because each device has its own address, the modem can be used in a broadcast network topology with one transmitter and multiple receivers.

Why did you make it?

A vast amount of DC low-voltage applications are DMX-driven. However, in most of the cases separate wiring is needed in order to transfer the DMX-frames. This can be an obstacle when upgrading existing systems which are already wired and wireless transmission is not an option. A typical application is a set of pool lights. Colorized electrical bulbs are replaced by new DMX-driven LED-based systems, using the existing wiring.

What makes it special?

It can be build-in in LED-modules or even used to send other information over power lines. The transmission is continious, repetititive and simplex. There is almost no protocol overhead which creates reaction speed very fast.
