Operation
Operating Concepts
If the configurer has turned on the option, you may redefine any MD destination. To do so is
simple: (1) select an MD destination on a selection button, (2) choose a destination that is not on
a selection button. You might have to navigate or scroll through a destination list to choose one.
Source
A source button selects a source. (Note that a quick source button selects a source and also
performs an immediate take.)
Quick source and source buttons are similar, except that the quick source performs a take. Be
aware of which buttons are quick sources so you do not perform an accidental take.
Normally, the button text is the source device’s mnemonic, but the configurer can assign any
text to the button.
See Preset Release on page 56 and Destination on page 52.
Source/Destination
A source/destination button selects both a source and a destination and optionally performs an
immediate take. The take is an all-level take.
A configuration option governs source/destination buttons. When the option is enabled,
source/destination buttons perform an immediate take, without requiring the operator to press
a take button.
When the option is disabled, the button merely selects the source and destination (on all levels).
The operator must then press the take button.
By default, the button shows the source name and the destination name, but the configurer
may assign other text to the button.
Source is Master
During data level (i.e., machine control) takes, this button makes the source device the master.
Otherwise, the destination is the master.
The button is a toggle that reverses the direction of data routing. For example, if the destination
is the master and the source is the slave, pressing a ‘Source is Master’ button reverses their roles.
Pressing the button again reverts the roles.
The ‘Source is Master’ button is used to initiate “broadcast” control routes. See Broadcast Routes
on page 61.
 Pressing the ‘Source is Master’ button turns off the ‘Broadcast’ button and vice versa.
The default button text is “Source Master” but the button can have any legend.
Take
In X-Y mode, a take button routes the preset source device(s) on selected levels to the selected
destination device.
In MD mode, a take button switches the preset source device(s) to the selected destination
device(s) on all levels.
The default button text is “Take” but the button can have any legend.
