2. Introduction
Chapter 2 provides an introduction to the NV8256-Plus Digital Video Router. It presents the following 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
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
on page 4. The routers can manage SD separately, or
Gb/s is called “3Gig.”
The NV8256-Plus is a robust system capable of supporting signal rate of 10
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 configurations. 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 example, 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.
Mb/s up to 3.0 Gb/s.
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 27.
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.
Caution If airflow is impeded, overheating may occur.
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 filters. For more information, see Maintenance
Signal Rates Supported

on page 59.
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 analog-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

Switching Configurations
The NV8256-Plus is designed to be highly flexible, enabling the creation of a variety of configurations 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
4 Rev 1.2 • 20 Oct 08
2. Introduction
can be doubled to a maximum of 512 inputs and 512 outputs. Each input card and output card manage 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 configuration 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 outputs. 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 functions. Slots are listed by location when facing the front of the router, as follows:
•Left Slot
•Center Slot
• Right Slot
Switching Configurations
— Manages all inputs and outputs for the local router (inputs 1–256).
— 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 54.
— 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 processing, 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. Output cards are only required on routers distributing outgoing signals through local coaxial connectors.
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
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 NVISION 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

2. Introduction
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
page 59.
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 containing connections for receiving and distributing signals and connecting to system functions, such
as a control system, alarms or references.

Output slots are similarly numbered,
such that output slot 1 corresponds to
outputs 1–16, output slot 2 corresponds 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 manages inputs 1–16. An input card
located in input slot 2 manages inputs
17–32, and so on.
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 crosspoint 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

2. Introduction
Rear Connections
The rear of the NV8256-Plus (Figure 2-4 on page 10) features a backplate containing BNC connections: 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 signals 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 expansion 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.

System Connections
The NV8256-Plus features connections for managing system functions, located on the rear of the
router. These connections enable you to connect to:
• A router control system using either serial, Ethernet, or GSC Node Bus connectors.
• A stable source of video signal for reference purposes.
• The UniConfig application, installed on a PC, used to perform configuration tasks.

Router Control System Connections
Router control systems are usually run on a separate unit (e.g., PC), which is then connected to the
router. The NV8256-Plus provides three different methods for connecting the router to a router control system: serial, Ethernet or GSC Node Bus. The router control system determines which connection is used. For example, to connect to the NVISION NV9000 control system an Ethernet
connection is preferred.

Serial Control Connections
The NV8256-Plus has four serial ports, as shown in Figure 2-6 on page 11. The ports are divided
into two sets, one primary (‘PRIMARY CONTROL’) and one secondary (‘SECONDARY CONTROL’). Primary control is the connection to the primary control card. Secondary control is the
connection to the secondary (optional for redundancy) control card. Each set is further divided into
connections that correspond to router control systems: ‘CTRL 1’ corresponds to the primary control system and ‘CTRL 2’ corresponds to an alternate control system. Using ‘CTRL 2’ connections,
you can connect to an alternate control system (i.e., backup system) or set up dual control, if
desired. For installation instructions, see Serial Control Connections
on page 38.
Serial control ports implement SMPTE 207M tributary.

Diagnostic
The diagnostic connections enable the NV8256-Plus to communicate with the UniConfig application. UniConfig runs on a PC separate from the router and is used to perform system setup tasks,
and configure and monitor the router. For information about using UniConfig, see the UniConfig
User’s Guide.
Diagnostic connections connect the router to the PC running the UniConfig application. There are
two types of diagnostic connections: temporary and permanent. A temporary diagnostic serial connection is located on the front of each control card. Permanent diagnostic connections are located
on the rear of the router, labeled ‘DIAG’, as shown in Figure 2-9. There are two permanent ‘DIAG’
ports, one primary (‘PRIMARY CONTROL’) and one secondary (‘SECONDARY CONTROL’).
The primary control connects to the primary control card. The secondary control connects to the
secondary (optional for redundancy) control card.

Router Control System Expansion Connections
In order to manage two connected NV8256-Plus routers, router control system expansion connections need to be connected between the routers. Router control expansion system connections are
located on the rear of the router, as shown in Figure 2-10.
When making router control system connections, only one router is connected directly to the router
control system. This router acts as the primary router. When making router control system expansion connections, connections from the remaining router, the secondary router, are made to the pri-
mary router. This enables the router control system to communicate with both routers through the
primary router.

Video Reference
The NV8256-Plus provides timing reference connections for video signals, labeled ‘VIDEO REF
1’ and ‘VIDEO REF 2’, as shown in Figure 2-11. Located on the rear of the router, these connections provide a reference input for determining the router’s video frame switch point. The video reference connections require a stable source of PAL, NTSC or tri-level sync.
If a video reference is present, signals switch at the defined frame and line switch points. If a video
reference is not present, the router still performs the switch, but to an internal reference. If a video
reference is not connected, the control card displays a lit red LED. (See Indicator LEDs
page 60.) For instructions on making video reference connections, see Making Video Reference
Connections on page 45.

Redundant and Dual References
There are two video reference connections. The same reference can be used for both connections or

connections, if one reference fails, the control card fails-over to the redundant reference. When
using different references, or “dual” references, switch takes can occur based on one or the other
reference. For example, ‘VIDEO REF 1’ uses NTSC as a reference and ‘VIDEO REF 2’ uses PAL
as a reference. Using UniConfig, the type of setting is selected: redundant or dual, and if dual,

The NV8256-Plus provides system alarms that send notification of a malfunction, such as when a
fan or power supply is not functioning properly. Alarms can be connected to indicators that display
visual signals when an alarm is activated. The NV6257 (power supply) and the NV8256-Plus each
have alarm connections that can be connected to external indicator. Creation of an external indicator is outside the scope of this manual. However, basic instructions on wiring the alarm connection
for external monitoring is provided. See Alarm Indicator Equipment

In addition to an alarm connection, the NV8256-Plus can be connected to a router control system
that receives status information from the router’s control card(s). See Making Router Control Sys-
tem Connections on page 37. The control card reads the status of NV6257’s power supply and fans
through the ‘Power Supply Monitors’ connection. (See Power Supply
on page 6.) In addition, the
control card monitors the router’s power supply, fans, and video reference connections. Both
NV6257 and router information is sent to the control system and is viewable using UniConfig.
A SNMP agent can be installed on the router control system (i.e., NVISION NV9000) to communicate system status information to a SNMP manager. Installation of SNMP agents and use of SNMP
managers is outside the scope of this User’s Guide.
The alarm connection is labeled ‘ALARM’ and is located on the rear of the router, as shown in

2. Introduction
Active Cards
The NV8256-Plus features several active cards that manage incoming signals, process commands
from the control system, perform signal switching, and distribute outgoing signals. Each card slides
into a card guide and has a lever that holds the card in place and aids card ejection.
There are:
• 2 control cards – one primary, one secondary (optional for redundancy)
• Up to 16 input cards – SD, SWB, 3Gig signals or analog-to-SD conversion.
• Up to 16 output cards – SD, SWB, 3Gig signals or SD-to-analog conversion.
• Up to 3 crosspoint cards – one primary, one optional for redundancy, and one for expansion.
• 1 monitor card (optional)
Each card and function is described in the following section. For information on installing cards,
see Installing Active Cards
Note All crosspoint cards in this section are referred to by the slot in which the card is

installed—left, middle or right—when facing the front of the router with the door
open.
Control Cards
The router has two control cards (EM0374), one primary and one secondary used for standby
(optional for redundancy). Each card receives commands from the router control system, and in
turn, controls the input, output, crosspoint and monitor cards. Only one control card is active at a
time, with the active card updating the stand-by card.
The control card includes a status reporting circuit. Four LEDs on the front of the control card indicate the card’s status: low battery (Red), alarm (Red), active (Amber) and “healthy” (Green). For
more information, see Indicator LEDs
on page 60.
Input Cards
The router frame can house up to 16 input cards, each processing up to 16 signals. Input cards
receive incoming signals through coaxial connectors or through expansion connectors when two
routers are connected together. There are three categories of input cards: Standard, filler, and analog-to-SD. The standard input card manages incoming signals from the coaxial connections and
from the expansion connections when two routers are connected. The filler input card manages
incoming signals only from the expansion connections when two routers are connected. Both standard and filler input cards can manage SD, SWB or 3Gig signals. Analog-to-SD input cards convert
incoming analog composite video signals to SD. Different categories of input cards can be intermixed in a single frame to meet specific switching configuration needs. For more information on
switching configurations, see Switching Configurations
The following is a list of the different input cards available. Each card is listed by the function it
performs (category)

Status Reporting
All input cards feature a circuit that performs status reporting and drives the card’s functions. Two
LEDs on the front of the input card indicate the card’s status: alarm (Red), power good (Green).
Three additional LEDs situated further back on the card indicate if software is loaded (Amber), if
there is good communication with the control card (Green) or bad communication with the control
card (Red). For more information, see Indicator LEDs
on page 60.
Input Card Functions
Input cards process up to 16 incoming signals. The functions of each type of card are described in
the following sections. Inputs cards are organized by category
— standard, filler or analog-to-SD.
Standard Input Cards
A standard input card manages either SD (EM0449), SWB (EM0437) or 3Gig (EM0619) incoming
signals from local coaxial connectors and from expansion connectors when two routers are connected together.
Each card receives 16 signals from the local coaxial connectors. Each of the 16 inputs is forwarded
to one of 16 cable equalizers. The equalizers equalize the signal and distribute three copies of the
signal. One copy is sent to a buffer and then the motherboard, which forwards the signal to the crosspoint card in the left slot (inputs 1–256). The second copy is sent to a cable driver and then the
motherboard, which forwards the signal to the expansion connectors. When two routers are connected together, the expansion connectors feed local signals to the second router. The third copy is
sent to a 2×1 MUX which selects a signal to send to the motherboard, which forwards the signal to
the crosspoint card in the middle slot (redundant crosspoint). For more information on each crosspoint card and crosspoint card slot functions, see Crosspoint Cards
If two routers are connected together, the standard input card also receives 16 inputs from the
expansion connections. Each input is forwarded to one of 16 cable receivers, which create two cop-

ies of the signal. One copy is sent to a 2×1 MUX and then a buffer. The buffer forwards the signal
to the motherboard, which sends the signal to the crosspoint card in the middle slot (redundant crosspoint). The other copy is sent to a buffer and then the motherboard, which forwards the signal to
the crosspoint card in the right slot (inputs 257–512).

Filler Input Cards
A filler input card manages SWB (EM0437-50) or 3Gig (EM0619-50) incoming signals from expansion connectors when two routers are connected together. Filler input cards receive signals only
through the expansion connections and not through the coaxial connections.
The filler input card receives 16 inputs from the expansion connectors. Each input is forwarded to
one of 16 cable receivers, which creates two copies of the signal. Both copies are sent to a buffer
and then the motherboard. The motherboard forwards one copy to the crosspoint card in the middle
slot (redundant crosspoint) and one copy to the crosspoint card in the right slot (inputs 257–512).

Analog-to-SD Input Cards
An analog-to-SD input card (EM0451) converts incoming analog PAL or NTSC composite video
signals to SMPTE 259M-C digital component signals (4:2:2, 270 Mb/s).
NV8256-Plus Digital Video Router • User’s Guide 17
2. Introduction
The input card receives 16 signals from the local coaxial connectors. Each input is forwarded to an
analog-to-digital converter that converts the signals to digital. Each digital input is forwarded to
one of 16 distribution amplifiers, which distributes three copies of the signal. One copy is sent to a
buffer and then the motherboard, which forwards the signal to the crosspoint card in the left slot
(inputs 1–256). The second copy is sent to a cable driver and then the motherboard, which forwards
the signal to the expansion connectors. When two routers are connected together, the signals are
forwarded to the second router through the expansion connectors. The third copy is sent to a 2×1
MUX and then the motherboard, which forwards the signal to the crosspoint card in the middle slot
(redundant crosspoint). For more information on each crosspoint card and crosspoint card slot functions, see Crosspoint Cards
If two routers are connected together, the analog-to-SD input card also receives 16 inputs from the
expansion connections. Each input is forwarded to one of 16 cable receivers, which create two copies of the signal. One copy is sent to a 2×1 MUX and then a buffer. The buffer forwards the signal
to the motherboard, which forwards the signal to the crosspoint card in the middle slot (redundant
crosspoint). The other copy is sent to a buffer and then the motherboard, which forwards the signal
to the crosspoint card in the right slot (257–512).

Crosspoint Cards
Crosspoint cards (EM0439) receive signals from the input cards (via the motherboard). The crosspoint card then performs switching as directed by the control card, sending signals to the output
cards (via the motherboard). Each crosspoint card can receive and distribute up to 256 individual
SD, SWB or 3Gig signals (signal rates from 10 Mb/s to 3.0Gb/s).
The crosspoint card slot into which the crosspoint card is installed determines which signals are
managed.
Left and Right Slot Functions
When facing the front of the router, crosspoint cards installed in either the left or right slots manage
signals as follows:
18 Rev 1.2 • 20 Oct 08
2. Introduction
•Left Slot — local inputs 1–256, received through local coaxial connections.
• Right Slot
(See Front Slots
Middle Slot Functions
An optional, redundant crosspoint card can be installed in the middle crosspoint card slot. When a
crosspoint card is installed in this slot, four buttons located on the front of the card becomes active.
By pressing one of two designated buttons, the crosspoint card can be set to take over active control
from another crosspoint card or act as a ‘hot” backup in stand-by mode. If set to take active control,
the redundant crosspoint card takes over the current functions of the crosspoint card installed in the
left or right crosspoint card slots. If set to be a backup, the card acts as a fail-over should the primary crosspoint card be removed. For details on redundant crosspoint card set up, see Setting
Redundant Crosspoint Card Switching on page 54.
The fourth button on the redundant crosspoint card enables you to use remote control to manage the
card. For information on using remote control, see Using Remote Control

Output Card Functions
Output cards process up to 16 incoming signals. The functions of the standard and SD-to-analog

Standard Output Cards
A standard output card manages either SD (EM0474), SWB (EM0444) or 3Gig (EM0620) signals
received from local crosspoint cards and distributes outgoing signals to coaxial connectors.
Each output card receives 16 inputs from each crosspoint card, which are forwarded to a 3×1 MUX.
The control card directs which crosspoint signal the 3×1 MUX selects. The 3×1 MUX sends the
selected signal to a re-clocker. (See Signal Rates Supported

SD-to-Analog Output Card
A SD-to-analog output card (EM0452) converts SMPTE 259M-C (4:2:2, 270
Mb/s) digital compo-
nent signals to PAL or NTSC composite video analog. Each output card receives 16 digital signals
from local crosspoint cards and distributes outgoing analog signals to coaxial connectors.
The SD-to-analog output cards perform the same functions as the standard output card, with one
exception: Instead of the 3×1 MUX sending the selected signal to a re-clocker, the 3×1 MUX forwards two copies of the signal. One copy is fed to a digital-to-analog converter, which converts the
signal to analog. The signal is then forwarded to a composite video encoder and an analog cable
driver, which sends the signals to a coaxial connector that distributes outgoing signals. The other
copy is sent to 16×1 MUX. The 16×1 MUX sends the output to the motherboard, which in turns
forwards the output to the monitor card for monitoring.

Monitor Card
A monitor card receives one signal from each output card and then sends two outgoing signals.
These outgoing signals can be sent to monitoring equipment for the purpose of monitoring outgoing signal quality. There are two monitoring cards available: one for SWB signals (1143408) and
one for 3Gig signals (EM0633).
The SWB monitor card receives video signal rates of 270
card receives video signal rate of 270
Mb/s, 1.5 Gb/s and 3.0 Gb/s. All other rates pass through.
There are two monitor connections. Using UniConfig, each connection can correspond to a unique
signal level, enabling the control system to monitor two signal rates at the same time. For more
information on levels, see the UniConfig User’s Guide.

2. Introduction
Depending on which monitor card is installed, the following levels can be configured:
• SWB Monitor Card – SD and SWB.
• 3Gig Monitor Card – SD and SWB, or SD and 3Gig, or SWB and 3Gig.
When two NV8256-Plus routers are connected together, the two monitor outputs on one router are
connected to the two monitor inputs on the other router through monitor expansion connections.
This enables the monitoring of all outgoing signals from both routers through a single set of monitoring connections. For information on making monitor connections, see Making Monitor Connec-
tions on page 45.
Frame Expansion
Two NV8256-Plus router frames can be connected together to create a switching matrix of up to
512 inputs and 512 outputs. The two frames are linked by connecting expansion connections on one
router to expansion connections on a second router.
The expansion connections are:
•I/O Signals
between two connected routers. All 8 connections must be connected. See Signal Expansion
Connections on page 36.
•Control System
system expansion connections, control system connections are also made between the two routers. This enables the control system to see both routers through one control system connection.
See Control System Expansion Connections
• Monitor System

Summary
When setting up the NV8256-Plus for the first time, or reconfiguring an existing router configuration, there are certain steps that must be performed. It is recommended that initial installation and
later reconfiguration tasks be performed in a specific order to avoid possible complications.
Perform installation and reconfiguration tasks in the following order:
1 Mount the router in a rack. If reconfiguring, skip this step if the router is already rack mounted
and not being remounted. See Rack Mount
2 Connect power, being sure to install PS6000 modules after power is connected. See Making
Power Connections on page 28.
3 Install active cards in the appropriate front card slots. If reconfiguring, remove cards and rein-
stall in the newly desired slots. Make sure that the appropriate backplane is installed for each
active card. See Installing Active Cards
4 Make connections between the source of incoming signals and the destination of outgoing sig-
nals, and the router. If reconfiguring, change signal connections to match new backplane and
active card configuration. See Making Signal Connections
5 Make connections between the router and the router control system. If reconfiguring, skip this
step if all necessary router control system connections are still adequate. See Making Router
Control System Connections on page 37.

How to Rack Mount the Router and the NV6257
1 Determine the placement of the router frame and NV6257 power supply frame in the rack, and
the rack in the facility. When placing the frames and rack, keep in mind the following requirements. (For details, see Frame Rack
on page 3.)
• The router requires 22RUs of vertical space.
• The NV6257 power supply requires 5RUs of vertical space.
• Be sure to locate the rack near an accessible AC source power outlet. The AC source is used
to power the NV6257 power supply, which supplies power to the router.
• To ensure proper cooling, leave space for unrestricted air flow through the front of the
router, and a minimum of six inches clearance at the rear where the cooling fans are located.
2 Locate the NV6257 power supply frame.
3 If the NV6257 was shipped with the PS6000 power supply modules in the frame, remove them
to make the frame lighter for installation.
Important Do not reinstall the PS6000 power supply modules. The modules are installed
after power is connected. For more information, see Connecting Power to the
NV6257 and the Router on page 29.
4 Lift the NV6257 frame into position and attach the NV6257 frame to the front of the rack with
the appropriate screws. Be sure to leave room for the NV8256-Plus frame to be mounted in the
rack. Place screws in all frame mounting screw holes.
5 Remove the front door by turning the retaining screws counter clockwise, opening the door, and
lifting it free of the hinges.
Caution Do not use the front door handle to lift the entire frame. Doing so may dam-
age the door.

Caution Handle all circuit boards with care. Be sure to use electrostatic discharge
(ESDI) protection and place the circuit boards in ESDI bags or on an ESDI
surface.
7 Lift the frame into position and attach the router frame to the front of the rack with the appropri-
ate screws. Be sure to place screws in all frame mounting screw holes.
Caution An equipment jack or two people are required to lift and install the router
frame. The router frame is considered too heavy for one person to lift and
install in the rack.
8 If removed, reinstall the fan tray in the fan slot at the top of the router. The tray is inserted right-
side up.
9 If removed, reinstall circuit boards. Be sure to install them in the correct location. For installa-
tion instructions, see Installing Active Cards
on page 32.
Making Power Connections
The power supply for the NV8256-Plus router is mounted externally in a separate frame, the
NV6257. The NV6257 uses the NVISION PS6000 power supply module. The NV8256-Plus
requires a minimum of four PS6000 power supply modules (plus four optional modules for redundancy).
The connectors and cables used to connect the router to the NV6257 are provided by NVISION, as
follows:
• Two, NV8256-Plus power supply cables (WC0085-00)
• One, NV8256-Plus monitor cable (WC0046-00)
The NV8256-Plus has a ground lug on the back of the router. Whether to ground or not is optional
and failure to connect the ground does not affect normal operation. However, grounding helps protect you and your equipment in case of a power anomaly such as a lightning strike.
Power Supply Monitor and Alarms Connections
The NV6257 has two DB25 connections, located on the rear. One connection, labeled ‘Power Supply Monitor’ carries alarm and temperature signals to the router. This connection is connected at
the same time the power connections are made. The other connection, labeled ‘Alarms’ presents
isolated alarm signals that can be connected to an external alarm indicator. For information on connecting NV6257 alarms connections, see Making Alarm Connections
on page 48.

3. Installation
Power Cords and Branch Circuits
For added protection in the event of a mains power failure, it is recommended that each power cord
connected to the NV6257 power supply be connected to a separate branch circuit. A wire bail can
be used to hold the power cable in place to reduce the possibility of an accidental disconnect.
The power cords are the only means of disconnecting AC power. Clearly mark the line side power
connection with its function so that in the event of an emergency, power can be disconnected
quickly.
Connecting Power to the NV6257 and the Router
The NV8256-Plus uses both power connections on the NV6257. To make this connection, NVISION provides two power cables (WC0085-00).
Caution Make power connections between the router and NV6257 before connecting the
Making Power Connections
NV6257 to an AC power source. Insert PS6000 power supply modules after con-
necting the NV6257 to an AC power source.
Connecting to AC power before the router is connected, or after PS6000 modules
are installed, may result in an electric shock.
How to Connect Power:
1 Locate the power cords, PS6000 power supply modules, and cables supplied by NVISION.
2 If not already removed, remove all PS6000 power supply modules.

Installing Active Cards
The NV8256-Plus router features several active cards that manage incoming signals, forwarding of
control system commands, signal switching, and distribution of outgoing signals. Cards slide into a
card guide such that the connectors on the rear of the card interface with the motherboard. Each
card has two levers—one at the top and one at the bottom—that help insert the card into place for
installation and eject the card for easy removal. For a description of each card, see Active Cards
page 15.
All cards can be inserted and removed with the power on.
How to Install Active Cards:
Caution Do not drop, roughly handle, or stack circuit boards. If a board does not easily
remove or insert, stop installation activities and contact NVISION Technical Support. (See Technical Support Contact Information

Making Signal Connections
In order for the NV8256-Plus to properly manage incoming and outgoing signals, the I/O connections on the rear of the router must be connected to cables that receive and distribute the signals.
The NV8256-Plus contains up to 256 input connections and up to 256 output connections.
If two NV8256-Plus routers are being connected together, the signal expansion connections need to
be connected between the two routers. These connections enable each router to send local inputs to
the other router. (See Signal Expansion Connections
Local Signal Connections
Cables are connected to the I/O connections using 75 Ω BNC connectors and coaxial cable. Connections must be made for each source of incoming signals and each signal distribution source.
How to Make Signal Connections
1 Locate the input connections at the rear of the router, as shown in Figure 3-5. There are 16 col-
umns of 16 BNC connections each.

Signal Expansion Connections
As a standalone router, the NV8256-Plus can manage up to 256 inputs and 256 outputs. Using the
NV8256-Plus signal expansion connections two routers can be connected, increasing the number of
signals managed up to 512 inputs and 512 outputs. Connected routers must be situated physically
next to each other, either top to bottom or side to side.
The NV8256-Plus contains 8 expansion connections, located on the rear of the router. All 8 expansion connections must be connected to properly connect two frames together. Each signal expansion connection manages 64 inputs. The connections are labeled according to the signals managed:
‘Inputs 1–64’, ‘Inputs 65–128’, and so on up to 512 signals. (See Figure 2-2 on page 8.) Facing the
rear of the router, the signals are labeled in descending order from right to left.
Making Signal Connections
4 Locate the output connections on the rear of the router, as shown in Figure 3-5. There are 16
columns of 16 BNC connections each.
5 For each output, connect to each output connection using a 75
Ω BNC connector and coaxial
cable.
6 Connect the other end of the cable to the distribution destination for the outgoing signal.
7 If connecting two NV8256-Plus routers together, connect the signal expansion connections.

Making Router Control System Connections
To manage signal switching in the NV8256-Plus, connections need to be created between the router
control system and the router.
Connections are as follows:
• Serial Control
connections.
• Ethernet Control
network connections.
• NVISION Aux Bus
Node Bus connection.
If connecting two NV8256-Plus routers together, only one router is directly connected to the router
control system. This router acts as the primary router. Additional control system expansion connections are then made between the primary router and the secondary, connected router. This enables
the router control system to communicate with both routers. (See Control System Expansion Con-
nections on page 41.)

NV8256-Plus Digital Video Router • User’s Guide 37
3. Installation
In order for the router control system to communicate with the router, Comm port and Baud rate
information must be entered in each control card using UniConfig. This information is entered
using a temporary diagnostic connection between the router and UniConfig. (See Temporarily Con-
necting to UniConfig on page 43.) After the information is entered, the router control system con-
nections can “see” the router and the router control system connections can be configured.
Serial Control Connections
Serial control connections are used to connect a router to the router control system. Serial connections are often used for third-party control systems. Although serial connections can be used for the
NVISION NV9000 control system, it is recommended that an Ethernet connection is used instead.
(See Ethernet Control Connections
The serial control ports are divided into two sets that communicate with the primary control card or
the secondary control card. Additional ports enable you to connect to an alternate control system
(i.e., backup system) or to set up dual control, if desired. For a detailed description of the serial control connections, see Serial Control Connections
In order for the router to communicate with the router control system through a serial connection,
Comm port and Baud rate settings need to be set in the control card.
Making Router Control System Connections
on page 39.)
on page 11.
Serial control connections use SMPTE 207M DE9 connectors and serial (RS-422/485) cable.
How to Make Serial Control Connections
1 Locate the serial control connections on the rear of the router, as shown in Figure 3-8. Serial
control connections are labeled ‘PRIMARY CONTROL’ for the primary control card and

Ethernet Control Connections
Ethernet control connections connect the router to the router control system using Ethernet connectors. Ethernet connections are especially helpful if the PC running the router control system is
going to be on a network. An Ethernet connection is recommended for the NVISION NV9000 control system.
The Ethernet ports are divided into two sets that communicate with the primary control card or the
secondary control card. For a detailed description of the Ethernet connections, see Serial Control
Connections on page 11. Unlike serial control connections, there are no Ethernet connections to
redundant control systems because redundant control systems can be connected through Ethernet
network connections.
In order for the router to communicate with the router control system through an Ethernet connection, an IP address for the router needs to be set in the control card. The IP address is set using UniConfig.
The Ethernet control system connections use RJ45 connectors and Cat5, or better, cable. The Ethernet port is 10/100BT.

Control System Expansion Connections
Control system expansion connections enable both routers to communicate with the router control
system when two NV8256-Plus routers are connected. When making control system connections,
only one router is connected directly to the router control system. This router acts as the primary
router. When making control system expansion connections, a separate connection is made from
the primary router to the secondary router. This enables the router control system to manage both
routers through the primary router connection. For simplicity, this procedure refers to each router as
the primary or secondary router.
When connecting two routers together, any unused control system expansion connections on the
secondary router must be terminated with a 50
The control system expansion connections are 10Base2 ports using 50

Router IP Address
If you are using an Ethernet connection between the router and the router control system, an IP
address for the router needs to be set on the control card. The IP address is set using UniConfig.
However, the PC running UniConfig cannot communicate with the router until an IP address for the
router is entered. To solve this problem, a temporary diagnostic connection to UniConfig can be
created, enabling you to enter the IP address before completing all router connections and configurations. (See Temporarily Connecting to UniConfig
temporary diagnostic connection can be disconnected and a permanent diagnostic connection
made. (See Permanently Connecting to UniConfig
on page 39.)
Temporarily Connecting to UniConfig
A temporary connection is created through the DE9 port located on the front of the primary control
card. The baud rate for this port is locked to 9600.

Making Video Reference Connections
The NV8256-Plus provides timing reference connections for analog video signals, labeled ‘VIDEO
REF 1’ and ‘VIDEO REF 2’. The control card uses these references to perform takes at the proper
point in time (per SMPTE RP168), determining the router’s video frame switch points. The video
reference connections require a stable source of PAL, NTSC or tri-level sync. Both video reference
connections use 75
erence connections, see Video Reference
Each ‘VIDEO REF’ connection can be use the same reference source (redundant) or two unique
reference sources (dual). For more information, see Redundant and Dual References
If a video reference is present, signals switch at the defined frame and line switch points. If a video
reference is not present, the router performs takes using an internally generated reference signal and
the control card displays a lit red LED. (See Indicator LEDs

Chapter 4 provides general operating information for the NV8256-Plus. It presents the following
topics:
•
Overview
• NVISION Control Systems
• Third-Party Control Systems
• Setting Redundant Crosspoint Card Switching
Overview
A router control system is required to use the NV8256-Plus router. The control system provides an
interface for operations and maintenance personnel. Through the control system, signal switching
can be actively configured, reference inputs selected, partitions for organizing signal switching created, and certain system functions monitored.
The NV8256-Plus is designed to partner with the NVISION NV9000 control system. However,
NVISION routers are designed with a degree of flexibility and can be used with certain third-party
control systems. For detailed information on using the NVISION NV9000 or NV910 control system, see the associated User’s Guide. For information on using third-party control systems, see the
third-party vendor literature. For more information on compatible control systems. For contact
information, contact NVISION. For contact information, see Technical Support Contact Informa-
tion on page iii.
NVISION Control Systems
Most facilities require multi-level switching capability (audio follow video, for example) and intuitive device naming capabilities. The control system used dramatically affects how operators use the
NV8256-Plus and the ease with which devices are accessed.
NVISION’s control system (NV9000) runs on a unit (e.g., PC) separate from the router. The router
control system can be loaded on a primary server only, or on both primary and secondary (redundant) servers, creating a fail-over backup. The control system hardware provides control panels for
managing routers and other network equipment.
NVISION’s control systems offer a variety of control surfaces, support redundancy, and facilitate
expansion as routing needs change. The control system is also capable of interfacing with thirdparty signal routing equipment. Because of the variety of features, capabilities and limitations of
other manufacturers’ equipment, users are urged to work closely with NVISION’s technical staff
and with the supplier of the third-party equipment when integrating it into an NV9000 control system.
NV8256-Plus Digital Video Router • User’s Guide 53
4. Operation
Third-Party Control Systems
NVISION provides assistance to users wanting to configure NVISION products to function with
third-party control systems. However, because NVISION does not manufacture or warrant control
systems from other vendors, we cannot guarantee overall performance or answer all possible configuration-related questions. For assistance, contact the manufacturer of the control system in use.
In many cases, router features and functionality are limited when using a third-party control system. For example, the third-party system may not optimally manage mono routing, while the
NV9000 control system easily manages this function.
Please consult with NVISION if you are considering using a third-party interface to control an
NV8256-Plus router. For contact information, see Technical Support Contact Information
page iii.
Setting Redundant Crosspoint Card Switching
Third-Party Control Systems
on
The NV8256-Plus crosspoint card features four buttons located on the front of the card. When the
card is installed in the middle crosspoint card slot —the slot for the optional, redundant crosspoint
card—the buttons become active and can be used to change which signals the crosspoint card manages. (See Figure 4-1 on page 55.)
By pressing a button on the front of the crosspoint card, the card can be directed to take over active
control of signal switching from another crosspoint card, become a standby crosspoint, or enable
external control. By setting the redundant crosspoint card to take over active control of the primary
card’s signals, a primary crosspoint card can be removed without experiencing any downtime.
The brightness level of the buttons indicate the current status: full-brightness indicates that the
remote and local control is active; half-brightness indicates local control only is active.

Using Remote Control
The redundant crosspoint card can be controlled remotely by creating an external circuit. To create
the circuit, use momentary switches with a series resistance of 50
connected in parallel with an LED cathode attached to ground (GND). The output signals are nominally +3.3
V. The selected diode should have a maximum forward bias current of 10 mA and maxi-
mum forward bias voltage of 1.5–2.2 V.

5. Configuration
Chapter 5 is a place-holder, essentially a pointer to UniConfig.
UniConfig
Before being placed into service, the NV8256-Plus router needs to be configured for your particular
facility and router control system. Configuration includes initializing ports so that the router and
UniConfig can communicate, setting up partitions, switch point settings, and testing switching configurations. Configuration tasks are performed using the UniConfig application, which resides on a
unit (e.g., PC) separate from the router. For detailed information on using UniConfig, see the Uni-
Config User’s Guide.

Chapter 6 provides maintenance instructions. It discusses the following topics:
• General Maintenance
• Fuse Replacement
• Indicator LEDs
• Air Flow
• Battery Replacement
• Troubleshooting
• Obtaining Service
General Maintenance
The NV8256-Plus does not require any periodic electrical or physical maintenance. Other than
cleaning the fan air intake filter, all that is required is periodic inspection of the system to make sure
no failures have occurred.
It is recommended that the system’s indicator LEDs be checked on a regular basis to ensure that the
system is operating properly. (See Indicator LEDs

on page 60.) It is also a good idea to regularly
Caution Only qualified service personnel should perform procedures in this section.
Fuse Replacement
Fuses are located on each of the frame modules. If a problem occurs on a module, it is a good to
check the fuses. The following table lists the fuses on each module:
Location Fuse Value
Power supply AC line fuse 8 Amp, 5 × 20 mm, slow-blow
Control card DC fuse 1 Amp, auto reset (not user serviceable)
Crosspoint card 1 Amp, auto reset (not user serviceable)
Warning Dangerous voltages are present at the rear AC power connector and on the power
supply module. Take precautions to prevent electric shock: Do not touch exposed
wires or connecting pins.
NV8256-Plus Digital Video Router • User’s Guide 59
6. Maintenance
Indicator LEDs
Indicator LEDs indicate whether AC power is present and if a card is operating normally. LEDs are
visible when the router front door is closed. In the following sections, LEDs are listed in the order
they appear on the cards, from top to bottom.
Power Supplies
The five green LEDs on the front of the power supply modules indicate presence of the five +48
VDC outputs of the five branch circuits. All five LEDs should be lit at all times when AC power is
present. If any LED is off, either the power supply has failed or the branch circuit is shorted.
Control Cards
The LEDs on the control cards can be monitored to determine whether the card is operating normally. The meanings of the LED indicators are as follows:
LED Indicator Indicator Function
Red (low battery) Normally OFF. If lit, indicates that the battery needs replacing. See Battery
Red (alarm) Normally OFF. If lit, indicates a problem or fault. Check the external reference

60 Rev 1.2 • 20 Oct 08
Normally ON. Indicates good communication with the control card.
Normally OFF. If lit, indicates that communication is not working properly with the
control card; the communication is “bad.”
6. Maintenance
Air Flow
The NV8256-Plus draws cooling air from the front of the router, through the door, and exhausts
heated air through the rear of the frame. The router must have the door properly installed and closed
for proper airflow through the chassis. For maximum air flow, regularly inspect router fans and filters.
Caution If airflow is impeded overheating may occur.
Fan Cleaning and Replacement
One plug-in fan tray containing three cooling fans is located at the top of the router frame. The tray
can be removed for inspection or cleaning by opening the frame front door, sliding the latches that
hold the fan module in place, and pulling the module out of the frame. If the fans become dusty or
clogged with lint, use a vacuum or compressed air to clean the dust off. Also check the openings at
the back of the frame where air enters and exits to be sure dust and lint have not accumulated.
The fan tray is easily replaced simply by sliding it out of the front of the frame and inserting a new
tray. The fans on the tray are held in place by four screws and a pluggable connector. To replace the
fans, remove the screws and unplug the connector.
Air Flow
Intake Filter Screen Cleaning
The NV8256-Plus has three fan filters. Two intake filters are located on the front door assembly. To
access the filters, open the router door by releasing the two thumbscrew locks and then slide the filters up and to the right to remove. This process may be easier if the entire door is removed by lifting it straight up while open.
The system can be operated safely with the door removed for short periods of time. If the filter is
only lightly contaminated with debris, clean the filter by vacuuming up loose debris or by blowing
air from the clean side to the dirty side. For filters badly loaded with debris, rinse with cold water or
wash with warm water and mild detergent. Be sure the filter is completely dry before re-installing
it.
Battery Replacement
If the red Low Battery LED indicator on the control card is lit, the battery located on the front edge
of the card needs replacing. Grasp the exposed edge of the battery with your fingers and pull it
towards you to remove it.
Important Do not use a metallic tool to remove the battery.
Call
NVISION for replacement battery information. For contact information, see Technical Support
Contact Information on page iii.

Troubleshooting
Many system troubles are caused by easily corrected errors, such as poor quality or missing input or
reference signals, incorrect configuration, and so on. This section lists common problems and their
solutions in the most likely order of occurrence. Refer also to the Introduction

Symptom Possible Causes and Solutions
System not powering up. Verify that the power cord(s) are plugged into the frame and the AC power source.
Use a voltmeter to verify the presence of power.
Check the AC line fuse on the PS6000 power supply module. See Fuse
Replacement on page 59.
One or a few cards or
PS6000 power supply
modules are not
powering up or not
operating properly.
Intermittent signal on
one or two outputs.
Check that the card or module is fully seated in the frame.
Reset the card or module by reseating it in the frame.
Check that all five green LEDs on the front of the PS6000 power supply modules
are lit. If an LED is not lit, it indicates a branch circuit may be faulty, which could
affect only certain modules in the frame. Replace the PS6000 power supply
module.
Check the PS6000 module and card fuses. See Fuse Replacement
Check input and output cable continuity and cable terminations.
Possible bad card. Swap each card in the signal path with another card to see if the
problem moves with the card. If so, replace the card.
If all cables, terminations, and cards check out OK, call Technical Support. (See
on page 59.
Technical Support Contact Information on page iii.)
Intermittent or missing
signals on all outputs.
Check the control card, which processes the references to produce sync. A
synchronous system requires an operational control card in order to pass signals.
An asynchronous system will operate in its last state even if the control card is
removed. Change over to the reserve control card to see if the problem goes away.
Possible low voltage on PS6000 power supply module. Check power test points
on the module. Voltages at power supply test points may be slightly high in lightly
loaded systems. Replace the PS6000 power supply module if any test points
indicate low voltage.
