Control-PC serial logging

3.1

Introduction

The Synoptic Microphone Control, Microphone Management and Startup DCN software application modules
can perform event logging and send the information to the serial ports of the PC. In the case of a multi-PC
DCN installation, this serial logging can be done on any of the connected PCs. It does not matter which PC is
running the application. Configuration settings for the serial ports are carried out in the Windows Control
Panel.

Microphone Activity logging

3.2.1 Introduction
Microphone Activity logging is done by the Synoptic Microphone Control and/or Microphone Management
application. It provides a compact real-time logging of all microphone and request-to-speak actions that take
place in the DCN system. A possible use for this feature is directing cameras to focus on the current speaker.
3.2.2

Configuration

This output is enabled by the "Microphone Activity logging to Aux" option in either Synoptic Microphone
Control or Microphone Management. By default it uses COM-port 2 on the local PC, but it can be routed to
any COM-port or even to a different PC by adding the following section to DCN.INI:
[MicActLogging]
ComPort=X
ComPortPCID=NR
where:
ComPort
ComPortPCID

Data layout

Each microphone action produces a short ASCII string terminated by a carriage return and newline character.
The string has the following layout:
<action code> <state> <seat number>
where:
action code
state
seat number
Examples:
$10001<CR><LF>
&30000<CR><LF>
#20B31<CR><LF>
*10034<CR><LF>

'X' is the COM-port number (1-4).
If ComPortPCID is omitted it defaults to the PC the DCN is
currently using. On a single PC system 'NR' is always 1. In
case of a multi-PC system, 'NR' is the number of the PC on
which the output must be produced. (The multi-PC server is 1,
the clients get a number in the range 2-10 using the Multi-PC
Config Utility.)

The seat number of the unit where the event occurred. This is
always a 4 character code consisting out of the characters 0 - 9
and A - Z. If necessary, leading zeros are added. If the 'state' is
3 the seat number is always '0000' (4 zeros) which is otherwise
an illegal seat number.
