Connecting A Bunch of Blade™ RGBW Fixtures

Fixtures on a serial data link must be daisy chained in one single line.

use of a DMX optically-isolated splitter may result in deterioration of the
digital DMX signal.

applications. Standard microphone cables will “probably” be OK, but note
that they cannot transmit DMX data as reliably over long distances. In
any event, the cable should have the following characteristics:
2-conductor twisted pair plus a shield
Maximum capacitance between conductors – 30 pF/ft.
Maximum capacitance between conductor & shield – 55 pF/ft.
Maximum resistance of 20 ohms / 1000 ft.
Nominal impedance 100 – 140 ohms
