DMX512 DC Powerline Modem

• Wide input voltage range: 14 to 35VDC
• Wide temperature range: 0-70°C
• FSK modulation at 60kHz
• Selectable number of RGB channels (1-8)
• Over current/temperature protection

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. 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. This 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.
