When using a DMX controller, the combined num ber of channels required by
all the fixtures on the DMX daisy chain determines the number of fixtures the
DMX controller has to support. Conversely, the number of onboard sliders,

USITT recommends limiting the total length of the DMX cable (from the
first fixture/controller to the last fixture) to 300~455 m (985~1,500 ft).
If you choose to create your own DMX cable, make sure to use data-grade

The DMX data cable must have the following characteristics:
Type: shielded, 2-conductor twisted pair
Maximum capacitance between conductors: 30 pF/ft
Maximum capacitance between conductor and shield: 55 pF/ft
Maximum resistance: 20 ohms/ 10 00 ft
