Abstract
Provided herein are methods and systems for powering a device, which include providing a data signal and extracting power from the data signal to power the device. The device may be either a device that responds to the data signal or another device. The data signal may vary between at least two data states. The methods and systems may extract power during one or both of the data states. The methods and systems may include a multiplexor. The controlled device may be an RS-485 compliant device, such as an LED system associated with a processor. The data signal may be a DMX-512 signal. The data signal may control a processor for control of the device.
