Zero88 DEMUX24 User Manual

DEMUX24 USER GUIDE
Specification Overview:
The Demux24 is a 24 channel DMX to analogue
converter, housed in a compact 1U 19" rack mounting
case.
The Demux24 is well specified, featuring four ring
locking DIN output connectors (each carrying six
channels), preheat and 4 output laws selectable per
channel, positive / negative polarity and DMX address
selectable per output socket, and manual level control
plus 12 memories for standalone operation. Remote
operation is possible by DMX, with optional end-of-line
termination.
Control Interface
The main display consists of four seven-segment
displays; the data displayed is dependent on the set-up
mode of the Demux24. Around the outside of these
displays are eight LEDs. Seven of which indicate the
current set-up mode of the Demux24, the eighth is used
for DMX indication.
The Demux24 has a default mode, for operation. In this
mode none of the set-up mode LEDs will be lit, the main
display will show the DMX address(es) and if it has
been terminated a small dot will be shown in the bottom
right of the fourth display.

Set-up Modes:
Manual Control:
The Manual Control Mode allows the user to set-up a
look on the outputs without the need of an external
controller.
Select „Manual‟ mode using the 'Mode' button. The
display will show CC.LL, where CC is the channel
number and LL is the level. Select the channel you
require or 'A' for all channels, using the 'Up & Down'
Arrows and press 'Enter'. Now set the level you require
using the 'Up & Down' Arrows and press 'Enter' again
to confirm and move back to the channel selection.
DMX Address:
There are 2 ways that the Demux24 can be patched – a
single DMX start address can be set for the block of 24
channels (block patch), or each output socket (6
channels) can be given a different DMX start address.
For block patch, the range of DMX start addresses is
001 – 489. In default mode the single DMX start
address of the block will be shown on the display.
For individual patch, the range of DMX start addresses
is 001 – 507. In default mode all four DMX start
addresses are cycled on the display.
Select „DMX ADDRESS‟ using the 'Mode' button, the
display will show S.AAA, where S is the socket number
and AAA is the current DMX address for that socket.
Select the socket you require (1-4), or 'A' for all sockets
(block patch), using the 'Up & Down' Arrows and press
'Enter'. Now set the address you require using the 'Up
& Down' Arrows and press 'Enter' again to confirm and
move back to the socket selection.
DMX Fail:
There are three DMX fail modes available – 'fade to
black', 'hold DMX' and 'fade to memory'.
Select 'DMX Fail‟ using the 'Mode' button. Using the
'Up & Down' Arrows select your preferred choice from
the list below;
