Sescom DMX1BK DMX lighting control cable sets the standard for a low-capacitance data pair in long distance DMX applications. It will always deliver true RS-485 data transmission and it features handy color-coded conductors for ease of installation. True DMX lighting control cable is based on RS-485 data cable, a 120 impedance and a capacitance of 12.5 pF/ft. or less. Many lighting designers use 100 cables for DMX because those cables are smaller, cheaper and easier to find. The impedance mismatch and higher capacitance will make them distance-limited compared to true RS-485. Among the 100 cable types are the premise/data cables such as Category 5, Category 5e, Category 6 and Category 6A. Using this cable for DMX is not the same as lighting control run with Ethernet, which use these same Category cables but in a completely different protocol ( i.e. Ethernet) with a 100m distance. The long and short of it.. Specify Sescom DMX1BK and be sure your have the right cable each and every time to get the job done. Features. True DMX512 Construction.
