ABSTRACT
The key to digital electronics lies in a circuit's ability to turn switches on and off electronically, and to interpret the results in a way that makes sense to humans. This allows a digital circuit to process data in the form of a logical "1" or a logical "0". A console or controller generates data based on the actions of a programmer or operator, and that data is sent to the devices under control, like lighting and fog machines, by transmitting it across copper wires, fiber-optic cable, or through the air with wireless data transmission. Digital data is often arranged in groups of eight bits, which is called a byte. Eight-bit binary numbers are not easy for human beings to use, so they are often broken into two four-bit numbers, which can easily be converted into two hexadecimal numbers. In devices that use dual inline package switches for setting the DMX starting address, a switch in the "off" position is considered a binary 0 and a switch in the "on" position is considered a binary 1.
