The figure below illustrates the Source Selection Bus.

Figure 2-6. Source Selection Bus

On the Source Selection Bus, each numbered button represents an input that you can

assign to a PIP or Key, or route to an Aux destination. Each input is either a direct

connection to a ScreenPRO-II or a router input. Please note:

• If you have configured a ScreenPRO-II to use internal routing (on the

Destination Setup Menu), both the white buttons (analog sources) and the

yellow buttons (HD-SDI/SD-SDI sources) are active. You can assign a maximum

of 16 analog and 2 HD-SDI/SD-SDI sources.

• If you have configured a ScreenPRO-II to use external routing (on the

Destination Setup Menu), only the white buttons are active. You can assign a

maximum of 16 sources, comprised of any mix of analog and digital.

Following are descriptions of each button’s function in the

Source Selection Bus.

Source Buttons — press to assign the source (analog or digital) to the blinking “mixer”

button in the

Layer Control Section. The following rules apply:

• When the source button is lit and blinking, the source is on Preview, the

associated layer is active for modification, and the associated layer’s raster box

blinks on Preview.

• When the source button is lit solid, the source is on Preview — but its associated

layer is

not active for modification.

• Multiple source buttons can be lit simultaneously, but only one source button can

be blinking — with its associated layer active for modification and the associated

raster box blinking on Preview.

• When the Red LED above a source button is lit solid, the source is on Program —

and its associated destination is enabled.

The Red LEDs only appear if the route’s associated

destination button is enabled. For example, if

Source 1 on

Destination 1 is on Program, the Red LED above Source 1

will turn off if Destination 1 is cleared.
