DMX Operation
The CFSound-III can be configured to be a DMX controller (Master) or DMX device (Slave). Upon
power-up, reset or CF card insertion, the CFSound-III looks for the presence of an installed DMX I/O
module. If found, the mode of DMX operation is controlled by the CFSOUND.INI file
IsMaster
parameter
as well as the presence of the DMX Scene or Fade filename attributes.
DMX Controller (Master)
The CFSound-III becomes a DMX controller (Master) when it finds files on the CF card with the DMX
Scene or Fade filename attributes, OR, when it reads the CFSOUND.INI file and finds a
[DMX]
section with
the
IsMaster
parameter set to TRUE (see the Filename Formats and CFSOUND.INI sections above). As a
DMX controller the CFSound produces the serial data stream that commands the daisy-chain connected DMX
devices to brighten/dim, move, pan or otherwise respond to their DMX channel values.
When a sound is played with the filename
F
ade attribute, the CFSound begins a fade-up of the channel
value with the same number as the sound. When the sound stops playing a fade-down of the channel value
occurs. The beginning and ending channel fade values as well as the fade duration can be controlled by
entries in the CFSOUND.INI file.
When a sound is played with the filename
D
mx scene attribute, the CFSound sets the first 16 channels
(increased to 32 channels in firmware v4.15 and later) to values obtained from an associated ##.DMX file –
the ## must match the two character sound number of the associated ##CDx.WAV or ##ODx.WAV file. The
content of the .DMX text files follow a similar format as the CFSOUND.INI file:

DMX Device (Slave)
The CFSound-III becomes a DMX device (Slave) when it finds no files on the CF card with the
D
MX
Scene or
F
ade filename attributes, OR, when it reads the CFSOUND.INI file and finds a
[DMX]
section with
the
IsMaster
parameter set to FALSE (this is the default, see the Filename Formats and CFSOUND.INI
