5 Installation

Discussion units operate by connecting in serial from the
CU 5905. Power, audio, and data are transported over a
single Cat5e cable from one discussion unit to the next.
This topology enables flexible and inexpensive installation
for large groups of people.

5.1 Rackmounting the CU

Install the CU 5905 Central Unit in a standard 19" rack
using the supplied 19" brackets. Remove the screws
holding the top and bottom covers, then attach the
brackets to the front of the unit using the same screws.

5.2 Cable Requirements

Shure offers cables designed specifically for the DDS 5900
system. The Shure EC 6001 are high-quality Ethernet
cabling available various lengths from 0.5 m to 100 m.
Each cable has been tested to ensure the best system
performance. See the accessories section for ordering
information on the EC 6001-xx.

5.2.1 Installed Cabling Recommendations
When designing a space with permanent cabling in the
floor or walls, terminate the cables to a patch panel. It is
more reliable (and easier) to crimp the cable to the female
shielded connecter on the panel. Then simply use short
jumper cables to connect to the discussion units.
The built-in fan draws air in on the left side and exhausts
air on the right, and so does not require extra space above
or below for cooling.
