IM7752 Demux24 Manual Issue 1.0.doc www.zero88.com Page 1 of 3

Specification Overview:

The Demux 24 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 3 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 Demux 24. Around the outside of

these displays are eight LED’s. Seven of which

indicate the current set-up mode of the Demux 24,

the eighth is used for DMX indication.

The Demux 24 has a default mode, for operation. In

this mode none of the set-up mode LED’s 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.

Mode Button:

The Mode button is used to cycle through the

different set-up modes. They are;

- Manual

- DMX address

- DMX fail

- Memory

- Preheat

- Law

- Polarity

- Default

Enter Button:

The Enter button is used to confirm actions.

Up & Down Buttons:

These are used to adjust the values shown in the

main display. Pressing both buttons together will

reset the display to the default values.

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 Demux 24 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;
