1 Switch to destination mode if necessary.
2 Press a VTR category button. (Suffix buttons become enabled.)
3 Press 4, then 2. The device is selected, but the name appearing in the destination display is
"PROD_A. "
In this example, you could press the 'Name Set Toggle' button a number of times to see that
PROD_A and VTR_45 are, in fact, the same device.
If you are using aliases, we recommend that you switch to the system name set during device
selection and switch back to your preferred name set afterward.
Note that when the panel is displaying aliases, and a device does not have an alias, the panel
displays the system name.

Broadcast Routes

It is easy and normal to route a source to multiple destinations for audio and video routers. In
contrast, machine control routes are typically point-to-point. Therefore, to control multiple
machines requires that you perform a "broadcast" operation using a 'Broadcast' button.
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.
