Product Summary
The NV8256-Plus manages standard-definition (SD), high-definition (HD) and 3.0 Gb/s (“3Gig”)
signal routing. See
on page 4. The routers can manage SD separately, or
SD, HD and 3.0 Gb/s signals combined. Support for SD and HD is called Super Wide Band (SWB).
Support for SD, HD, and 3.0
Gb/s is called “3Gig.”
The NV8256-Plus is a robust system capable of supporting signal rate of 10
Mb/s up to 3.0
Gb/s.
This enables you to invest in a single router to meet current routing needs and potential future
growth as industry standards evolve.
The router features a flexible I/O design enabling the implementation of a wide range of configura-
tions. A single NV8256-Plus can manage up to 256 inputs and 256 outputs. Using expansion ports,
two routers can be connected together to manage up to 512 inputs and 512 outputs. Within one
router, or between two connected routers, configurations can start at 16 inputs and 16 outputs,
increasing in increments of 16, up to 256 per router. Because inputs and outputs are independent,
configurations are based on 16, but do not have to be squared (i.e., 256×256, 512×512). For exam-
ple, if using the NV8256-Plus as a standalone router, switching configurations of 16 inputs and 256
outputs, 32 inputs and 256 outputs, 256 inputs and 48 outputs, and so on are valid. Similarly, if two
routers are connected together, non-square configurations of inputs and outputs can be created,
increasing in increments of 16 up to a maximum of 512 inputs and 512 outputs.
In addition, the NV8256-Plus features conversion of video signals from analog composite to SD
and SD to analog composite.
Frame Rack
The NV8256-Plus mounts in a rack with minimum dimensions of 22RU high by 19
″ wide by 18″
deep. When placing the rack in your facility, be sure to leave enough space for air flow through the
