Installation; Rackmounting The Cu; Cable Requirements - Shure DDS 5900 User Manual

Installation

Microphone units operate by connecting in series from the central unit. Power, audio, and data are transported over
a shielded Cat 5e cable from one unit to the next. This topology enables flexible and inexpensive installation for large
groups of people.

Rackmounting the CU

Install the 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.
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.

Cable Requirements

Shure offers cables designed specifically for the DIS line of conferencing and discussion equipment. The Shure EC 6001
are high-quality Ethernet cables available various lengths from 0.5 m to 100 m. Each cable has been tested to ensure
reliable system performance. See the accessories section for ordering information on the EC 6001-xx.
Important: Cables and connectors must be shielded for stable system performance. If an installation does not use
Shure EC 6001 cables, they must follow the Cat5e cable requirements.
Cat5e Cable Requirements
Using Patch Panels
When designing a system with a patch panel, crimp the cable to the female shielded connecter on the panel. Then simply
use short jumper cables to connect to the discussion units. Make sure the chain is always terminated by a discussion unit
or a termination plug included in the SPS CU spare parts package.
