Operation
Operating Concepts
During broadcast, the source device controls one or more destination devices.
Making Broadcast Routes
Follow these steps to broadcast control signals:
1 Ensure that the panel is in “source is master” mode. It is either in “source is master” mode by
default or you must press a ‘Source is Master’ button to activate the mode. The mode is
active when the ‘Source is Master’ button is high-tally.
2 Select a destination and preset a source. Then press ‘Take’.
3 Press the ‘Broadcast’ button.
4 Select a destination and preset a source. Then press ‘Take’.
5 Repeat steps 3 and 4 to add other machines to the set of controlled devices.
 In MD mode, with hold mode active, you can select multiple broadcast destinations with a
single take.
Implicit in the ‘Broadcast’ button is the “source is master” mode. It is not necessary to press
‘Source is Master’ repeatedly. The reason you must press ‘Source is Master’ the first time is that
“broadcast mode” is not yet active.
Removing Broadcast Routes
To cancel a route, route the source to another destination normally.
To remove a destination from the set of broadcast destinations, route another source (e.g., the
free source) to the destination.
Data Routing
There are 3 data routing options that affect sources and destinations that have a machine
control level (i.e., a data level). These options govern what happens when a source or destina-
tion device is to be used.
Automatic Data Routing
A take involving a machine control level occurs naturally on all selected levels, including the
machine control level, regardless of whether an affected machine control port is in use. The
system breaks any existing control connections involved with the source and destination and
makes a new control connection for the source and destination.
This data routing option applies in both operating modes.
Manual Data Routing
If a control port for the source or destination is “in use,” a take involving a machine control level
occurs on all levels except the machine control level. You must break either the source’s control
connection, the destination’s control connection, or both of those existing connections before
you can take the source to the destination on the machine control level. To break a connection,
route a device (as a source) to itself (as a destination) on the machine control level. When the
connection is broken, the status column of the display reads “FREE” for the machine control
level (in X-Y mode). If your panel is in multi-destination mode, you might switch to X-Y mode
momentarily to see this.
