The problem of controlling the computer control system of multichannel lighting devices is considered. Basic means of lighting control systems are determited. Generalised structure system for controlling of multichannel lighting devices is developed. Expediency of use of trunk serial interfaces in such systems is substantiated. Efficiency of use of DMX protocol is subsnantiated and analysed. The structural scheme of multichannel lighting devices control system according to such a protocol and the general algorithm of system operation are considered.
