Linking Desks
Linking Desks to operate as Master/Slave
1
Decide which of the desks is to be the Master.
There may be more than one Slave. The limit
is set by the MIDI specification and local
operation conditions.
2
Ensure that all desks are programmed to use
the same MIDI channel.
On the Master desk, set the Mode switch to
MIDI Setup Out; the Memory display shows
‘Ch’ and the Step display shows the MIDI
transmission channel No.; Change if required.
On each Slave desk, set the Mode switch to
MIDI Setup In / Slave; press Page + once, the
Memory display shows ‘Ch’ and the Step
display shows the MIDI reception channel
No.; ensure it is the same as the Master desk
transmit channel.
3
Set Mode to Presets or Run on the Master
desk and to MIDI Setup In / Slave on the
Slave desk(s).
4
Connect a MIDI cable from MASTER OUT on
the Master desk to MIDI IN on the first Slave
desk. Continue with a cable from the Slave
MIDI OUT to the next Slave MIDI IN and so
on as required.
In MIDI Setup In / Slave mode ONLY, the Out
signal is a repeat of the In signal, duplicating
the MIDI Thru function.

Note
If any desk has been connected to another
MIDI instrument (not a Lightmaster XLS),
Linking may not work. Turn all desks off and
then on again to reset them if this is the case.

Notes - Linking Desks
*
Linking
Linking an XLS to an XLS or a XL only works in Presets or
Run Mode. The Master desks remotely operates the second
desk, which becomes a dumb slave, the Mode Switch, +, -
and the Go button still operate for desk setup.
*
Linking an XLS to an other XLS.
In Preset Mode
The linked desk becomes a 48 channel 48 channel
Auxiliary memory desk.
In Run Mode
The linked desk becomes a 48 c 48 channel
Auxiliary memory desk with 24 Memory Masters.
This means that in Run Mode on the Slave desk the Memory
Masters and their Flash buttons do not work ( 24 Memory
Masters Only ), but Preset A still operates.
*
Linking an XLS to an XL.
In Preset Mode
The linked desk becomes a 36 channel 24 channel
Auxiliary memory desk.
In Run Mode
The linked desk becomes a 36 c 24 channel Auxiliary
memory desk with 24 Memory Masters.
The XL is limited to its original Specification, E.G. 1 Effects
Master and no Auxiliary control.
*
Number of Linked Desks
The number of desks that may be linked is not defined. The
exact number will depend on cable lengths and electrical
environment.
Special devices are available from other suppliers to increase
the number of linked instruments.
In MIDI Setup in / SLave Mode set “op” to “24" if the Slave
desk in an XLS. If the slave is anXL then set to ”12".
It is not possible to slave an XLS from an XL.
*
Soloing
In Presets mode, soloing a channel only affects the outputs of
the desk on which the Solo button is pressed.
*
Audio
All audio is connected to the Master only. The Master will
control the Slave(s) as required.
*
DMX Output
Each desk will need to be attached to a seperate DMX
receiver.
*
Sequences
These are driven from the Master effects section. For
sequences to work properly. they must be programmed very
carefully.
Desks do not link in Program mode, so each desk must be
programmed separately.
For example:
Setting up a 48 channel chase on two desks:
Program steps 1 to 24 as usual on the Master, followed by
steps 25 to 48 as blank steps.
On the Slave, steps 1 to 24 must be blank, steps 25 to 48 to
be programmed as required.
Note that if a sequence (No 4 for example) on the Master is
programmed, but on the Slave is unprogrammed, there will be
no output on the Slave. Similarly, if sequence 4 is
programmed on the Slave but not on the Master, this
sequence cannot be accessed by the Master
Notes - General
*
Transfer of Memories from the main desk:
The secondary desk does not have to be specially set up to
have memories transferred to it.
If the secondary desk is in MIDI Setup In/Slave mode, its
memories cannot be overwritten in error.
*
Loading memories from a programmable MIDI
device (e.g. a computer):
If there is a programmable MIDI device connected rather than
a Zero 88 lighting desk, the result of this Load request will
depend on what the device is programmed to do on receipt of
a Zero 88 System Exclusive code of 00 20 0F: it will probably
be ignored.
All data is dumped using system eclusive messages only; if
your sequencer can store system exclusive messages and
replay them it may be used to store and load data to and from
a Lightmaster XLS.
