USB-Stick
The DMX Audio Unit needs an USB stick as data medium for the mp3 audio files.
Use only USB sticks with maximum 16GB.
The USB-Stick must be formatted with the file system FAT32.
The mp3 audio files must be must be located in the main directory of the USB
stick.
All file names must be 5-digit with the ending .mp3
The first audio file must be named 00001.mp3, the second 00002.mp3, and
so on.
If the playback sequence is incorrect, the USB stick must be formatted. Then
the files are to be transferred to the USB stick one after the other, starting
with the first one (00001.mp3).

DMX-Audio Unit 7
DMX Address
The start address can be set via the DIP switch.
Switch 1 has a value of 20 (=1), switch 2 has a value of 21 (=2) and so on up to
switch 9 with a value of 28 (=256).
The sum of the values of the switches set to ON corresponds to the start address.
Address Switch Address Switch

The RDM parameter DMX_STARTADDRESS can also be used to set the
DMX start address.
A DMX start address set via the DIP switches has priority over the start
address set via RDM.

playback stops.
Loop Play The audio file is played back in a loop. After the audio file ends, the
playback of this file starts again.

DMX Fail Behavior
In case of a DMX signal failure (DMX fail) the DMX Audio Unit can continue the
current playback (HOLD), stop the playback (OFF) or execute a predefined saved
setting.
Via the RDM parameter DMX_FAIL_MODE or the setting directly at the device the
DMX failure behavior can be adjusted.
After a power failure the held DMX values are not restored by the HOLD
function. In this case the values are set to 0 (OFF).

DMX-Audio Unit 11

RDM
RDM is the short form for Remote Device Management.
As soon as the device is within the system, device-dependent settings can occur
remotely via RDM command due to the uniquely assigned UID. A direct access to the
device is not necessary.
If the DMX start address is set via RDM, all address switches at the DMX-
Audio Unit must be set to OFF ! A DMX start address set by the address
switches is always prior !
