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

applications. Standard microphone cables will “probably” be OK, but
note that they cannot transmit DMX data as reliably over long distanc-
es. 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
