2. Introduction
Chapter 2 provides an introduction to the NV8256-Plus Digital Video Router. It presents the fol-
lowing topics:
•Product Summary
•Signal Rates Supported
•Switching Configurations
•Power Supply
•Module Slots and Rear Connections
•Active Cards
•Frame Expansion
Product Summary
The NV8256-Plus manages standard-definition (SD), high-definition (HD) and 3.0 Gb/s (“3Gig”)
signal routing. See Signal Rates Supported 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 10Mb/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

front of the router and within easy access of an AC power source. For installation instructions, see
Rack Mount on page 25.
Cooling
The router has a fan tray housing three fans. The fan tray is located at the top of the chassis and
accessed from the front of the frame. The fans draw cooling air from the front of the router, through
the door, and exhaust it through the rear of the frame. The router must have the door correctly
installed and closed for proper airflow through the chassis.
There are three removable air filters: two are located on the inside of the door assembly and one
inside the router. It is recommended that you perform regular maintenance on the fan tray and fil-
ters. For more information, see Maintenance on page 57.
Signal Rates Supported
The NV8256-Plus supports SD, HD, 3Gig and analog composite video signals. Incoming analog
signals are converted to digital format for internal routing. Outgoing SD signals can be converted to
analog composite for distribution.
The following table lists the SMPTE standard and rates for SD, HD and 3Gig signals, and for ana-
log-to-digital and digital-to-analog conversion. Each signal type is managed by a specific input or
output card (circuit board). For a description of each card and corresponding card part number, see
Input Cards (page 15) and Output Cards (page 15).
Switching Configurations
The NV8256-Plus is designed to be highly flexible, enabling the creation of a variety of configura-
tions for managing incoming and outgoing signals. A single router can manage a maximum of
256 inputs and 256 outputs. By connecting two routers together, the number of signals managed

2. Introduction
Switching Configurations
can be doubled to a maximum of 512 inputs and 512 outputs. Each input card and output card man-
age 16 signals each. This means that switching configurations can be based on 16, increasing in
increments of 16, up to the maximum number of inputs and outputs allowed. Each switching con-
figuration is created by installing crosspoint cards, input cards, and output cards in specific slots on
each router.
Crosspoint Card Slots and Managed Signals
The crosspoint card manages signal switching with each card managing up to 256 inputs and out-
puts. The router frame has three slots for housing crosspoint cards. (See Figure 2-2 on page 8.)
Depending on the slot in which it is installed, the crosspoint card performs different switching func-
tions. Slots are listed by location when facing the front of the router, as follows:
•LeftSlot
—Manages all inputs and outputs for the local router (inputs 1–256).
•CenterSlot
—An optional crosspoint card can be installed for redundancy as a backup for
another crosspoint card. The crosspoint card can take over active control from the crosspoint
card installed in the left slot or right slot, but not both. For more information, see Setting
Redundant Crosspoint Card Switching on page 52.
• Right Slot —Manages all signals received through the expansion connections. The crosspoint
card receives signals from a second, connected router (inputs 257–512) and sends the signals to
local outputs 1–256.
Because the crosspoint cards installed in a specific slot manage specific outputs, depending on your
configuration, not all crosspoint cards may need to be installed. For example, if only outputs
1–256 have output cards, then a crosspoint card is only required in the left slot. The right slot can
remain empty. The middle slot is optional.
For more information on inputs and outputs and assigned numbers, see Slots and Corresponding
Signal Numbers on page 9.
Combining Input Cards and Output Cards
When connecting two routers together, different combinations of input cards and output cards can
be installed to meet switching configuration needs while minimizing cost. ‘Standard’ input cards
receive signals from the router’s local input connections and from a second, connected router
through expansion cables. ‘Filler’ input cards receive signals only from expansion cables when two
routers are connected together, but not local inputs. Because filler cards perform less signal pro-
cessing, they are less expansive then standard input cards. If a switching configuration requires two
routers, but local inputs to only one of the two routers, filler cards can be used in the router not
receiving local inputs.
Output cards manage outgoing signals. If a router is only used for receiving incoming signals, such
as in a 512 inputs and 256 outputs configuration, output cards are not needed on both routers. Out-
put cards are only required on routers distributing outgoing signals through local coaxial connec-
tors.
Examples of Switching Configurations
The following table lists possible switching configurations when two routers are connected
together. For each configuration, the table lists in which slot crosspoint cards are installed, on

Power Supply
which router, what type of input card is used, and if the router requires output cards. For a descrip-
tion of each type of card, see Active Cards on page 15. The two connected routers are listed as
Router 1 and Router 2. Although the examples list a full complement of input cards, the number of
cards installed depends on the number of inputs and outputs being managed by a specific switching
configuration. The optional, redundant crosspoint card (installed in the center crosspoint card slot)
is not included in the following examples. Only required crosspoint cards are listed.
Power Supply
The power supply for the NV8256-Plus is an external, separate frame, the NV6257. The NV6257
uses the PS6000 series power supply module. The NV8256-Plus router requires four PS6000 power
supply modules. For redundancy, an additional four PS6000 modules can be installed. The NV6257
can house a total of four primary and four redundant PS6000 power supply modules. This means
that one NV6257 power supply frame can power one NV8256-Plus router frame.
The PS6000 power supply module accepts a wide range of AC input voltages and produces five
+48 VDC outputs. The power supply automatically senses the AC input voltage (90–130 and 180–
250 VAC) and adjusts to maintain a relatively constant DC output; no voltage selection is required.
The five regulated outputs are directed to modules in the router where on-board regulators produce
the DC voltages required by the local circuits. Each +48VDC output powers one of the five green
LEDs and output test points located on the front of the power supply. Under normal operation, all
five LEDs are lit. For more information, see Indicator LEDs on page 58.
Figure 2-1 shows the power supply architecture.

2. Introduction
Module Slots and Rear Connections
Fuses
Fuses for AC power inputs are located on the PS6000 power supply modules. When an NV6257 is
ordered, fuses appropriate for line voltage in use at the country of destination are installed on the
PS6000 power supply modules. Be sure to check the fuse ratings for compliance with specific
requirements in your area. A 7.5 A fuse is required for 90–130 VAC applications. For 180–250 VAC
operation, a 3.75 A fuse is required. For information on replacing fuses, see Fuse Replacement on
page 57.
Cooling
There are four low-speed fans located along the front edge of each PS6000 power supply module.
Each fan pulls a small quantity of air across the internal heat sinks. An additional fan on the
NV6257 frame also provides cooling and is serviceable.
Module Slots and Rear Connections
The NV8256-Plus has slots for input, output, monitor, control and crosspoint cards. Cards are
installed in slots from the front of the router frame. The rear of the router is a solid backplate con-
taining connections for receiving and distributing signals and connecting to system functions, such
as a control system, alarms or references.
Front Slots
Figure 2-2 on page 8 shows the front of the NV8256-Plus with the door removed. From this view,
in the slots that do not have an active card installed (right-hand side), the backside of the backplate
and the motherboard connections are visible. The router features 16 upper bay slots for output cards
and 16 lower bay slots for input cards. In the center of the router are three vertical slots for cross-
point cards. Above the crosspoint card slots is the monitor card slot. Near the bottom of the router
frame are two horizontal slots for the control cards. For more information on each type of card, see
Active Cards on page 15.
From this view, the fan tray at the very top of the router chassis is also visible. For more informa-
tion on frame cooling, see Cooling on page 4.

2. Introduction
Module Slots and Rear Connections
Slots and Corresponding Signal Numbers
If the NV8256-Plus router is used as a standalone router, up to 256 incoming signals can be
received and up to 256 outgoing signals distributed. The crosspoint card installed in the left cross-
point card slot manages inputs 1–256. If two NV8256-Plus routers are connected together, signals
coming into one router can be sent to a second, connected router. This can double the number of
signals managed by the two routers to a maximum of 512 inputs and 512 outputs. The crosspoint
card installed in the right crosspoint card slot manages inputs from the second router: 257–512.
A crosspoint card installed in the middle slot acts as a redundant crosspoint card for fail-over. For
more information on crosspoint cards, see Crosspoint Card Slots and Managed Signals on page 5.
For information on installing cards in modules slots, see Installing Active Cards on page 30.
Figure 2-3. Inputs and Outputs, Numbers Assigned (Front View)
Each input card slot and output card
slot, and the card it holds, receives or
distributes signals through 16 BNC
connectors. Each signal is assigned a
number that corresponds to the physi-
cal input or output connection. The
numbers correspond to the slot in
which an input card or output card is
installed. This means that input slot 1
corresponds to inputs 1–16, input slot
2 corresponds to inputs 17–32, and so
on, up to 256, as shown in Figure 2-3.
Output slots are similarly numbered,
such that output slot 1 corresponds to
outputs 1–16, output slot 2 corre-
sponds to outputs 17–32, and so on,
up to 256, as shown in Figure 2-3.
Similarly, the location of an input card
or output card in the router frame
determines the inputs and outputs
managed by that card. For example,
an input card located in slot 1 man-
ages inputs 1–16. An input card
located in input slot 2 manages inputs
17–32, and so on.

Module Slots and Rear Connections
Rear Connections
The rear of the NV8256-Plus (Figure 2-4 on page 10) features a backplate containing BNC connec-
tions: 256 for receiving signals and 256 for distributing signals. These connections are passive and
pass the signals through to active, receiving connections on the input cards and output cards.
An additional set of four BNC connections, located in the upper, center area of the frame, send sig-
nals to the monitor card. In the lower region of the frame are connections for system and power
functions, as shown in Figure 2-5 on page 11. In the center of the frame are connections for expan-
sion cables used to send signals between two connected NV8256-Plus router frames. In Figure 2-4
on page 10, the expansion connections are shown with the cover plates still on.
