Operation
Operating Concepts
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 61 and Destination on page 56.
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 67.
 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.
Undefined
An undefined button cannot be used and appears dark (unlit) on the panel. The term “unde-
fined button” has meaning primarily to the configurer and not the operator.
VFD/SEL Toggle
The button is toggle. In one state, it reads “Paging VFD” and makes the display (VFD) scroll when
the operator presses ‘Page Up’ or ‘Page Down’. In the other state, it reads “Paging Sel Buttons”
and makes the items on selection buttons scroll. The selection buttons represent layers when
the panel is in X-Y mode and represent destinations in MD mode.
If your panel does not have a ‘VFD/SEL Toggle’ button, it will do one of two things:
