with an internal fuse. Under normal operating conditions, the fuse should
notrequirereplacement.Thefuseiseldreplaceable,howeveritisan

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
