Nomenclature
The ‘Location’ column uses abbreviations for card locations. This is what they mean:
• I-nnn — input card in slot nnn (for NV8144s and NV8280s)
• LI-nnn — input card in slot nnn of the lower bay (for NV8576s and NV8576-Pluses)
• UI-nnn — input card in slot nnn of the upper bay (for NV8576s and NV8576-Pluses)
• Main: LI-nnn — input card in slot nnn of the lower bay of the main frame (for expanded
NV8576-Pluses)
• Main: UI-nnn — input card in slot nnn of the upper bay of the main frame (for expanded
NV8576-Pluses)
• Expansion: LI-nnn — input card in slot nnn of the lower bay of the expansion frame (for
expanded NV8576-Pluses)
• Expansion: UI-nnn — input card in slot nnn of the upper bay of the expansion frame (for
expanded NV8576-Pluses)
The ‘Module’ column also uses abbreviations. (See Nomenclature on page 50.)
Context Menu
You can change input port settings on an individual basis. Use standard click, shift-click, and
control-click methods to make your selection.

the video switch. Different video and audio formats require different switch points.
You can set switch point parameters for individual outputs in the ‘Output Attributes’ page.
The attributes table controls the type of switch point, but not the actual moment in time of the
switch, relative to the reference signal. Diagnostic equipment or specialized software is required
for that.
The ‘Output Attributes’ page also has reference signal controls. (Switch points are affected by
the reference signals.)
Reference signals are connected at reference connections on the router frame. Video reference
connects at two ports labeled VIDEO REF1 and VIDEO REF2. These connectors can receive the
