7.4 Master-Slave Operation
When controlling more than 16 scans, two Scancommander or an additional
Extension unit (see 7.6) can be linked in a master-slave mode. All operations
are controlled via the master board, at the slave only the display and the single
scan selection buttons keep on working.
7.4.1 Installation
MIDI OUT connector of the master has to be connected to
MIDI IN at the first slave unit.
More slaves can be added using the MIDI THRU port of the previous slave
The DMX output of all coupled units can be used as separate DMX lines.
Via the DMX input and by patching all scans to different DMX address
numbers, the control signals of more than one Scancommander can be send
on one DMX line.
7.4.2 Starting the couple mode
The first step is to prepare the slave units
REMOTE at the Top Menu
MIDI
MODE SLAVE has to be inverted
The last step is to set up the master board via REMOTE - MIDI - MODE
MASTER. If a SLAVE is used with a software version smaller than 4.20 it is
then really necessary to press the button "Mode: Old master".
The following RESET will send all necessary data from the master to all slave
units. If any slave comes later than the master, it will wait for a master reset
(lowest display button left side or switching off and on the master power
supply).
7.4.3 Working on master-slave mode
As far as the setups are not done before starting the couple mode, the first
steps will be SETUP LAMPTYPE, DMX and MOVEMENT.
All functions including trackerball movements, group selection and brightness
master are send from the master to the slave units.
Just the single scan selection button have to be operated at the according
units. To make sure that during DMX PATCH and MOVEMENT SETUP only
one scan is handled at a time, all other scans have to be deselected manually.
Instead of a second Scancommander, a 19" Scancommander Extension can
be used as slave (see 7.6).
