DDS 5900 Digital Discussion System
Connecting Microphone Units and DCS-LAN
Components
Microphone units and DCS-LAN components are connected in sequence (daisy-chain) using the two RJ45 ports
on each unit. The connectors are interchangeable; simply connect the previous unit to one port, and the following
unit to the other port. Always use shielded Cat5e (or higher) cabling for reliable system performance.
Power, control data, and audio are transported from one unit to the next over the same shielded Cat5e cable.
To protect the equipment, ensure that the central control unit (CCU) is always off when connecting or disconnect-
ing the microphone units. Use any of the four chain outputs (A, B, C, and/or D) for connecting DCS-LAN compo-
nents.
1. Power off the CCU to protect the equipment during set up.
2. Connect a chain output on the CCU to the first microphone unit with the shielded Cat5e cable.
3. Connect the rest of the microphone units in sequence, using the RJ45 jacks on the bottom of each unit.
4. Turn on the CCU by pressing the power button. The microphone units will power on. The unit is stable once the
control button LEDs stop flashing.
Note: Do not turn off CCU power until the system has stabilized

Connection Diagrams

The following system diagrams illustrate typical hardware connections to the DIS-CCU central control unit. Actual
installations may use different combinations of hardware, but follow the general concepts outlined below.
Note: Flushmount and portable discussion units are interchangeable in the following drawings, unless noted.
Basic Setup with Discussion Units
The system is operational without the use of a computer. Use the CCU navigation screen to set up the installation.
Note: This setup does not support the Manual microphone mode, since the browser interface is required for turn-
ing microphones on and off.
