2 Introduction and document overview
The DCS 6000 system offers the possibility of controlling the microphones from a PC, AMX or other
external control unit via a serial connection. This text documents how this feature is used; how
external control of the DCS 6000 system is executed.
The protocol used on the cable between the central unit (CU) of the DCS 6000 system and the external
control unit is described in general in section 3.
Parts of this protocol encapsulate the protocol used on the DCS 6000 bus and thus enable the CU and
the external control unit to communicate as if the latter was a unit on the bus. The parts of the DCS
6000 protocol, which are relevant for controlling the microphones are described in section 4.
Section 5 summarizes and exemplifies how to use the protocol described in sections 3 and 4 to control
the microphone application.
Additional detailed examples are shown in section 6.
2.1 Restrictions in DCS6000
The RS232 protocol control described herein provides descriptions for an external control unit to do
microphone control, audio settings and voting in the DCS6000 system. Basic functionality is hereby
made available, however some restrictions need mentioning:
- The Voting control functionality is protected by a license feature within the CU.
- There is no support for Dual microphone units or units sharing a microphone.
- There is no support for Voting units without microphones.
For voting functionality to become available, the CU must be provided with a CU license key that
enables voting and voting control through the RS232 connection.
2.2 Voting Concepts
2.2.1 Voting session
Voting sessions are controlled (setup/opened/closed) from an external control unit.
First, the following voting parameters must be setup from external control:
- Voting Type (3-Button Voting or 5-Button Voting)
- Secret Voting (Open Voting or Secret Voting)
