ATTENTION
The screened parts of the cable (sleeve) must never be connected to the system’s earth, as this would cause
faulty fixture and controller operation.
Over long runs can be necessary to insert a DMX level matching amplifier.
For those connections the use of balanced microphone cable is not recommended because it cannot trans-
mit control DMX data reliably.
