Sirius 24 and 48
DMX Output Kit
Installation and
Operation
Instructions

Introduction
This kit will give a Sirius 24 or a Sirius 48 the
ability to control up to 512 DMX channels, and
enables the user to define his own output patch.
Each desk channel can be programmed to control
any number of dimmer channels via DMX512,
with analogue outputs functioning simultaneously.
Using the DMX512 protocol eliminates the need
for bulky and expensive multicore cables by using
only three wires to control all 512 channels.
DMX512 is the most widely used digital
communication system between lighting desks
and DMX devices such as dimmers, colour
scrollers and moving lights
Controlling the Dimmers
The DMX output from the Sirius will normally be
connected directly to dimmers with DMX 512
inputs or to 0 to 10v input dimmers using one or
more Zero 88 demultiplexers.
(eg Demux 48 - Stock No 00-276-00).
Cable Details
The maximum cable length between a Sirius and
a Demultiplexer will depend on several factors
including:
Type of cable used
Number of DMX devices connected in the line
Electrical environment
Zero 88 recommend that shielded twisted pair
cable approved for RS422/485 (eg. Belden 9841
or Proplex PC222P) is used.
Communication over a hundred metres should
normally be possible without problem, for longer
cable runs it may be necessary to fit a DMX
Termination Plug (Stock No 00-269-00) to the last
DMX device in order to ensure completely error
free data transmission. It is good practice to
allways use a Termination Plug
Substitution of microphone or other types of cable
may be possible, but data transmission errors are
more likely, particularly over long distances.
Installation
Some modifications may be needed to your desk
to allow this DMX kit to be fitted. All Sirius from
serial number: 283950 have been modified.
To find out if your Sirius has been modified, follow
instructions below to remove the back of the
desk.
Find the microprocessor PCB,
(two in the Sirius 48).
Compare it with this sketch
Is there
a 2 way
connector
present
in the position
shown ?
If there is, your desk HAS BEEN modified, so
continue with these instructions..
If your Sirius is not modified, then go to the
enclosed modification kit, follow instructions to
modify the PCB’s then refit the PCB’s, and then
continue with these instructions.
Installation
Fitting the Sirius DMX Kit
Remove the bottom covers:
1Switch off the desk; remove the mains lead
and the key.
2Carefully turn the desk over with the outputs
away from you.
3Remove the ten screws in the large bottom
panel that are nearest you.
4Remove the four screws (two in each side
plate) that secure the wide rear plate
containing the rubber foot.
5Remove the bottom panel assembly.
REASSEMBLE IN THE REVERSE ORDER
To fit the DMX kit
1Remove the hole plug from the spare hole in
the rear (connector) panel (see diagrams).
2Pass the three wires through the hole, and fix
the XLR connector in place using the two
small self tapping screws provided.
3You may find it easiest to connect the 3 XLR
wires to the screw terminals on the DMX
board at this stage. The connections are:
XLR 5 DMX board
Pin 1 Yellow 0V (Signal Common)
Pin 2 Red 1- (Dimmer drive complement)
Pin 3 Black 1+ (Dimmer drive true)
4Locate the three fixing holes for the DMX
board (see diagrams), and fix the DMX pcb in
place using the long screws and grey spacers
provided.
5Locate the 5 changeable links at the end of
the DMX board, and set the end one to the
‘24’ position if the board is to be installed into
a Sirius 24, or to the ‘48’ position for a Sirius

48. Leave the other links in their factory set
positions as shown on the cover.
6Locate the four Main Board Power Supply
wires and unplug them from the Power
Supply. Plug this into the 4-way connector on
the DMX board.
7Plug the 4 wire flying lead from the DMX board
into the Power Supply.
FOR SIRIUS 24 ONLY:
See Figure 1
Connect the 16-way ribbon cable from the DMX
board to the connector on the Right Hand Button
Board (EM5774; on the left as shown in Figure1).
Take care to insert the connectors the correct
way around.
There are now two screen cables left coming
from under the DMX PCB.
Plug the connector of the longer cable into the 2
way connector now fitted to the main processor
PCB as shown here. Ensure that the colours are
fitted the correct way around as shown. The
spare cable should be coiled up and secured out
of the way.
FOR SIRIUS 48 ONLY:
See Figure 2
Locate the 16-way ribbon cable connecting the
Outer Right Hand Button Board (situated just
above the Power Supply) to the Inner Right Hand
Button Board (EM5774). Unplug this cable from
the Inner Right Hand Button Board and plug it
into the socket on the DMX board. Plug the flying
cable from the DMX board into the socket on the
Inner Right Hand Button Board. Take care to
insert the connectors the correct way round.
There are two screened cables coming from the
DMX PCB. Plug the longer cable into the 2 way
connector now fitted to the main processor PCB.
Plug the shorter cable into the similar 2 way
connector on the slave processor PCB. Ensure
that the colours are fitted the correct way around
as shown in Figure 2.
*Note
DMX Card
The screened cables are attached to the DMX PCB with Molex
connectors the RED wire on these connectors need to be
nearest the Ribbon cables.
Removing DMX Card
Should the DMX card be removed, the Sirius 48
will only function as 24 channel desk unless the
two way connectors are linked with a screened
cable.Take the cable with two way connectors at
each end and fit as shown in Figure 3.
Note that the screen at one end of the cable is
soldered to the 0V point show in Figure 3.
Slaved desks
Where two Sirius desks (24 and/or 48) are being
used in a Master and Slave configuration, one
DMX Kit is needed for each desk, Each desk then
gives its own DMX output. The two DMX
supplies then need to be connected
independently to its own Demultiplex unit.

Output Patch
With the DMX board installed, the Sirius is ready
to operate with DMX outputs. The default
configuration is for desk channels 1 to 48 drive
DMX channels 1 to 48 respectively, ie. desk
channel 1 drives DMX channel 1, desk channel 2
drives DMX channel 2, etc up to 48 (or 24 for a
Sirius 24).
It is possible for the user to program desk
channel 1 to drive DMX channel 6, and desk
channel 2 to drive DMX channels 7, 36, and 89
and so on.
The Output Patch can only be programmed when
in Super User mode.
To Access Super User:
1Turn the Keyswitch to Presets Only
2Press and hold down the Effects + and -
buttons, then turn the keyswitch to Program;
release both buttons. The Memory No display
shows SUPER USER; the Autofade display
shows the software version number. Note
DMX will only work with software versions
4319 and above.
To Program the Patch:
1Select the Output Patch:
Use the Memory + and/or - buttons to find
‘OUTPUT PATCH’ (see over page for Super
User operation) Note: This option can only be
selected when the DMX board is installed.
Press the Memory Program button to select
this option; the display shows ‘Out 001 ch 01’
This means that DMX output channel 001 is
being driven by desk channel 1
2To select the desk channel which drives a
DMX output channel, press the Channel Flash
button for the channel you wish to choose.
For example, pressing Channel 9 flash button
sets ‘Out 001 ch 09’ This means that DMX
output channel 001 is now being driven by
desk channel 9.
Pressing the memory + (and/or -) buttons will
cycle through DMX channels 001 to 512. Each
of these outputs can be patched to any desk
channel simply by pressing the appropriate
Channel Flash button.
Whenever a change is made to the output
patch the outputs are re-routed
instantaneously.
3To turn a DMX output channel off:
Press the channel Flash button again. For
example, pressing Channel 9 flash button
again sets ‘Out 001 ch — ‘ This means that
DMX output channel 001 is now turned off.
4When Output Patching is complete:
Press the Memory Program button to return
you to the ‘Output Patch’ option in the Super
User menu.
Clearing the Output Patch
Selecting the Super User ‘Clear All’ option will
clear all memories and reset DMX output. DMX
channels 1-48 to desk channels 1-48 respectively
(or 24 for a Sirius 24), with all other channels
turned off.
High Speed Data Transmission
Sirius only transmits those DMX output channels
which have been programmed. By keeping
programmed channels within a small number
range, and unused channels turned off, the
fastest possible refresh rate will be achieved.
