DDS 5900 Digital Discussion System

Some examples of functionality available using the protocol:

• Setting a microphone in speak or in request

• Retrieving a list of seats available in the system.

This interface supports applications developed by customers, so the protocol is deliberately kept simple. The Ex-

ternal Control protocol offers a means for supplementing the control functionality available through the DDS 5900

Browser interface and the DIS-CCU interactive display, however some commands and settings available in the

browser interface and on the DIS-CCU interactive display are not available using the 'External Control Protocol'

Customer applications can include but are not limited to AMX or Crestron room control systems, PC or micro

controller based applications, e.g., for button mimics and camera control applications.

General Protocol Behavior

A TCP/IP socket connection to the DIS-CCU must be established for the External Control protocol to become

available. Configuration of the DIS-CCU connection to the Ethernet must be defined from the CCU interactive front

plate control/Browser interface and an IP address for the DIS-CCU must be assigned in the network.

Choose either a static IP address or an IP address assigned through DHCP. It is convenient to ensure, that the

DIS-CCU ends up with the same IP address at each start up.

Knowing the IP address, the only additional information required for setting up a TCP/IP connection is the Port

Number:

Port Number = 3142

Example: Test connection to CCU via Putty : If the DIS-CCU is assigned IP address 192.168.1.100, the external

application must connect the TCP/IP socket to the address 192.168.1.100:3142.

Knowing the IP address of the DIS-CCU a connection can be set up using a simple terminal program like Putty.

1. Download at http://www.putty.org (http://www.putty.org)

2. Start Putty.

3. Insert IP address and Port Number.

4. Select 'Raw' for the Connection Type.

5. Press 'Open' to establish connection to the CU. Control is now possible.

6. Type 'help' to see a list of commands available.

Command Structure (from External Control to DIS-CCU)

To control the CCU an External Control sends commands to DIS-CCU included in command lines. Command lines

are build up in a very simple manner:
