DMX512 is the lighting in the work of a high-frequency words, and how computer lamp? computer lamp control and how to do?
Intelligent lights typically use DMX512 control protocol control lights of various actions. This control protocol called 512 Protocol in the industry. It is a dedicated full digital signal control protocol, compared with analog signal, it has a signal more stable, flexible and convenient way to control, and is not vulnerable to environmental interference, etc. Therefore, DMX512 signal is by far the most popular control signal. DMX signal can control all 512 channels.
Typically, an intelligent lights on the occupation of a channel operation. If the computer lamp, a color wheel to change the color on the occupation of a channel, if computer lamp with two color wheel to change the color on the occupation of two channels. Computer lamp function, the more it occupied by a channel number. Generally speaking, the number of channels determine the computer lamp performance. Features of PC lamp only 4 or 8 channel but powerful PC lamp can have as many as 38 channel. This high-performance computer lamp, an action can consume 2 or more channels. For example, high-performance computer lamp horizontal movement is divided into fast horizontal movement and accurate horizontal movement; a computer lamp strobe is divided into a stroboscopic, random strobe, slow light fast charge light strobe light, fast and slow your light strobe and so on many kinds of effects, strobe will occupy more than one channel.
Because all the DMX signal can only control 512 channel, therefore, in the design of computerized light control system must take into account a DMX control line behind all computer lamp channel number and cannot be greater than 512 channels. Otherwise, it must increase the DMX signal input number to resolve. Each additional way DMX signal, it is necessary to increase the signal line all the way to independence.
