Orbis – Quick Start Guide
Connection of microphone units with redundancy
• For maximum reliability of the system, the microphone units/system units are connected in a ring
to the control unit. As cables use standard CAT5e cables (S/UTP, min. AWG 26 diameter or better).
• At maximum you can connect 50 microphone units/system units. The big advantage of this
connection is the present redundancy, i.e. should a cable fault occur at one side of the microphone
unit/ system unit, the unit will not fail, as it is still supplied from the cable on the other side. The
cable concerned or the defective microphone unit/system unit can be replaced during operation
without failing all other microphone units/system units.
