Product Summary

The NV5128 Multi-Format Router is a highly flexible router supporting audio and video signals,
both analog and digital, in a variety of combinations. (See Signals Types and Rates
router can support up to 128 inputs and 128 outputs (256 inputs and 256 outputs mono), typically
organized in a block of 16 inputs and 16 outputs, expandable in increments of 16. A fully non­blocking matrix architecture, allows for one-to-one and one-to-many routing.

For audio signals, the NV5128 routes stereo signals internally as mono channels, enabling the
recombination of channels to create new stereo signals. Analog audio signals are routed internally
as digital signals. Converters housed on I/O cards convert incoming analog signals to digital and
outgoing digital signals to analog as needed.

For video signals, the router can manage Standard Definition (SD) separately, or SD and High Def­inition (HD) signals combined, referred to as Super Wide Band (SWB). Analog video signals are
routed internally without being converted to digital. However, an Analog Video Converter (AVC)
card is available for the conversion of analog to digital and digital to analog.

on page 5.) The

Additionally, longitudinal time code signals and machine control signals can also be routed within
the same frame enabling you to meet unique switching needs.

Active input cards, output cards, and control cards are “hot swappable” and installed through the
front of the frame for easy access. The rear of the router features a back plate into which backplanes
housing different types of connectors for receiving and distributing signals are installed. Each back­plane receives or distributes signals for a single active card allowing for maximum switching con­figuration flexibility: backplanes are not pre-installed in pre-selected router slots. The back plate
also contains connections to system functions, such as a router control system, alarms or reference
signals.

Mounting

The NV5128 is designed to mount in a standard EIA rack with minimum dimensions of 8RUs

deep. Because of the router’s compact size, multiple routers can be mounted in a single rack, saving
facility space. For installation instructions, see Rack Mount

Fuses

Active cards feature a “fast blow” or resettable fuse. If the card requires a large amount of power,
the fuse is “fast blow” and must be replaced if blown. If the fuses are resettable, the fuses either
reset automatically or can be reset manually by removing the card from the frame. For more infor­mation on fuses, see Fuse Replacement

Cooling

The NV5128 frame has a single fan tray containing three fans with variable fan speed control. 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 installed and closed for proper airflow through the
chassis.

Caution If airflow is impeded, overheating can occur.

on page 37.

on page 76.

Each fan features speed control which spins the fan at the optimal rate required to ensure that a con­stant temperature is maintained within the router. Temperature sensors on the fans sense the exiting
temperature and speed up or slow down the spinning of the fan as required. By spinning only as
needed to meet cooling needs, fan noise is significantly reduced in partially loaded frames or in
environments with lower ambient temperatures. In addition, by maintaining a constant temperature,
circuitry life span is increased.

Each fan features two LEDs that indicate if the fan is receiving power and if there is a failure. For
more information, see Indicator LEDs

Filters

There is a removable air filter located on the inside of the door assembly. It is recommended that
maintenance of the fan tray and filters be performed on a regular basis. For more information, see

Air Flow

Power Supply

The NV5128 uses the PS6000 power supply module, housing one primary module and one optional
module (for redundancy). The PS6000 power supply module accepts a wide range of AC input
voltages and produces five +48

Fuses

A fuse for the AC power inputs is located on the PS6000 power supply modules. When a NV5128
is ordered, fuses appropriate for the 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. An 8A fuse (part number HB0145-00) is required for 90–130
cations. For 180–250

The fuses are “slow blow” and designed to blow if there is an ongoing power issue, but not if there
is a single, minor spike in the power flow. For information on replacing fuses, see Fuse Replace-

The NV5128 supports several signals within a single router. Supported audio signals are analog,
AES synchronous and AES asynchronous. Supported video signals are analog, SD, and SWB (SD
and HD combined). Also supported are SMPTE longitudinal time code and machine control sig­nals.

Incoming audio analog signals are converted to digital with a sample rate of 48kHz for internal
routing and can be distributed externally as digital audio outputs. Conversely, incoming digital
audio signals can be converted and distributed externally as analog audio outputs. In addition, all
stereo signals are separated into left and right channels for switching as mono signals. Mono chan­nels can be recombined to create new stereo signals. This unique architecture allows for cross-con­version between analog and synchronous AES signals within the same frame.

Analog and digital video signals can be intermixed with any other supported video format (analog,
SD or SWB) while maintaining a high level of analog video performance, effectively replacing
many single format routers already in use.

Signal Rates

The following table lists the sample rates and how many signals at each rate an input card or output
card can support. Each signal type requires a specific input card or output card. For a description of
each card and corresponding card part numbers, see Active Cards

Mixing Analog and Digital

The NV5128 frame can mix analog and digital signals within a single routing system. For example,
a digital audio input can be routed to an analog audio output. To perform this action the router uses
analog-to-digital (A/D) converters and digital-to-analog (D/A) convertors.

There are two types of A/D and D/A converter cards: one set for audio and one set for video. Ana­log audio converter cards cannot be mixed with analog video converter cards. The input signals
type

— audio or video — must match the output signal type. For more information on converter

cards, see Active Cards

The following is a list of audio and video inter-mix options and related delay times.

Mono Channels

AES signals are composed of several parts, including a preamble, left channel, right channel, user
bits, and channel status bits. When received as an AES signal, the signal is retained as an AES sig­nal for internal routing to the output card. The crosspoint array on the output card breaks apart the
signal, separating out the left and right channels to create two mono channels. The mono channels
are then switched as separate signals, recombining left and right channels into new stereo signals.
The channel status bit and user bits are passed through. When the signal is distributed as an AES
output, the preamble, channel status bit and user bits are added back to the left and right channels to
create a stereo signal.

Individual left or right channels can be combined with other individual channels and distributed as
a new channel-pair combination (stereo signal). For example, a live news report may capture the
news reporter’s voice on the left channel and the background noises on the right channel. By split­ting the AES signal into its left channel and right channel, the news reporter’s voice (left channel)
can be paired with a different background noise (right channel). If only one channel is present, the
other channel is silent.

To perform mono switching, an external AES reference signal must be connected to maintain syn­chronization (see Making Reference Connections

NV5128 Multi-Format Router • User’s Guide 7

and routed to outputs is determined by the router control system. For more information on mono
signal switching, see Setting Jumpers and Switches on Cards and Card Sets

Switching Configurations

Switching is performed by the output card. Each output card receives signals from the input card
via the motherboard and routing commands from the control card. The inputs are then sent to a
crosspoint array on the output card that performs the switching.

Figure 2-2 shows the basic architecture of the NV5128 switching configuration and the relationship
between the backplanes and the input cards and output cards. Backplanes house connections that
receive and distribute signals to and from the router. For more information, see Backplanes
page 13.

Each “X” (crosspoint symbol) represents a 16 input x 16 output crosspoint array. Taken together,
eight crosspoints create a 128 input x 16 output crosspoint array. This unique architecture creates a
fully non-blocking matrix such that an input can be switched to any output, and one input to one
output, or one input to many outputs.

Figure 2-2. NV5128 Crosspoint Architecture

In general, input cards and output cards follow the 16 inputs x 16 outputs architecture, with one
router card slot per card. There are three exceptions: Classic SWB card sets, Standard SWB cards
and machine control card sets. Each card set switching configuration is discussed in the proceeding
sections.

2. Introduction

Module Slots and Rear Connectors

Classic SWB Switching Configurations

The Classic SWB card set is composed of two cards connected together that occupy two card slots.
The card set has a 16 input x 16 output crosspoint array. A single Classic SWB card set can be used
to create a 16 input x 16 output switching matrix, or a pair of card sets can be coupled together to
create a 32 input x 32 output matrix. The 32 input x 32 output configuration feeds the 16 inputs
from one Classic SWB card set to the second Classic SWB card set and vice versa.

When creating a 32 input x 32 output matrix, the Classic SWB cards must be installed in specific
router slots. For installation instructions, see Installing Classic SWB Backplanes

on page 28.

on page 41. For

Standard SWB Switching Configurations

There are two types of Standard SWB output cards: a main card with a “wing” and optional expan­sion cards that mate with the wing on the main card. The output cards occupy four contiguous slots.
By installing the main card and up to three expansion cards, different crosspoint matrices can be
created. Because the main output card receives all 128 SWB inputs, switching configurations can
start at 16 inputs x 16 outputs, increasing in increments of 16 up to 128 inputs by 64 outputs. A sec­ond set of Standard SWB main output cards and expansion output cards can be installed, increasing
the switching configuration to 128 inputs x 128 outputs.

The Standard SWB cards must be installed in specific router slots. For installation instructions, see

card architecture, see Standard SWB

Machine Control Switching Configurations

The machine control card set is composed of two cards connected together that occupy two card
slots. The machine control card set is bidirectional; it carries signals in both directions (input and
output).

A single machine control card set can support 32 ports. If a second machine control card set is
installed and combined with the first card set, the configuration can be doubled to 64 ports.

Module Slots and Rear Connectors

The NV5128 has slots for input cards, output cards, and control cards. Cards are installed through
the front of the frame for easy access and are “hot swappable”. The rear of the router is a back plate
into which backplanes housing connectors for receiving and distributing signals are installed. The
back plate also contains connections to system functions, such as a router control system, alarms or
reference signals.

Active circuitry is contained mainly on the input cards, output cards, control cards, power supply
modules, and fan tray installed through the router’s front. However, some active circuitry for SD
and HD signals are located on the associated backplanes, which are installed through the router’s
rear. All cards and backplanes are “hot-swappable.”

NV5128 Multi-Format Router • User’s Guide 9

2. Introduction

Module Slots and Rear Connectors

An internal motherboard spans the frame and interconnects front and rear modules, and distributes
control signals, timing information, and power. Cards, power supply modules, and the fan tray plug
into the motherboard from the front of the router and backplanes plug into the same motherboard
from the rear. Each input card and output card has a corresponding backplane. For more informa­tion on each type of card, see Active Cards

Backplanes

on page 13.

Front Slots

Figure 2-3, next page, shows the front of the NV5128 with the door removed. In the center of the
router are eight slots designated for input cards. To the right and left of the input slots are four slots
designated for output cards. On the far right, two slots house the primary and secondary control
cards. A fan tray is located at the top of the router chassis.

Viewing the frame from the front, slots are numbered 1 through 16, from left to right. (See
Figure 2-3.)

Each slot supports 16 channels, as follows:

• Slots 1 through 4 (for outputs): Slot 1 switches output channels 1 to 16, slot 2 switches output
channels 17-32, and so on.

on page 21. For more information on backplanes, see

• Slots 5 through 12 (for inputs) receives and process inputs 1to 128 respectively, in groups of 16
channels per slot, in ascending order, left to right, viewed from the front of the frame.

• Slots 13 through 16 (for outputs) are similar in function to slots 1 to 4, except that the output
channels are in reverse order. That is, slot 13 switches output channels 113 to 128, slot 14
switches 97 to 112, slot 15 switches 81 to 96 and slot 16 switches 65 to 80. The reverse order of
the output channels in the right-hand side of the frame is intentional; it makes it easier to obtain
equal path lengths on the frame’s motherboard, facilitates analog video timing, and facilitates
the use of Classic SWB card sets and machine control card sets installed in slots 11 to 14 (see

Each backplane contains connectors for
receiving or distributing signals. The
number of connectors on a backplane
and the type of connector is determined
by the type of signal. Figure 2-5 shows
the four types of connectors available on
backplanes.

There are five types of backplanes. All
backplanes are passive unless otherwise
noted:

• DB25 connectors

— Used for analog

audio signals.

• Phoenix connectors

— Used for AES

balanced signals and SMPTE longi­tudinal time code signals.

• RJ45 connectors

— Used for machine

control signals.

• BNC connectors

— Used for analog

video and AES unbalanced audio sig­nals.

• BNC connectors (active)

— Used for

incoming and outgoing SWB signals
and for incoming SD signals.

Figure 2-5. Backplanes

Important The two backplanes containing BNC connectors are not interchangeable. The

BNC backplane for SD and SWB signals are active and can not be used for ana­log video or AES audio signals.

The type of signal being received or distributed determines the backplane used (see Backplane

Types and Signals on page 14). For each backplane installed a corresponding input card or output

card must also be installed. For example, if a backplane is installed to receive AES unbalanced sig­nals, then the input card capable of routing AES unbalanced signals must be installed in the corre­sponding card slot (see Active Cards

on page 21).

Video Backplanes

Unlike other backplanes, the backplanes for incoming and outgoing SWB signals and incoming SD
signals have active components. These backplanes cannot be used with analog video cards.

ence. (See Using Video and Audio References on page 6.) For optimum audio output, signals must
be clock-locked to the same reference. Input impedance is selected by setting jumpers on the con­trol card. (See Control Card Jumper Settings

The NV5128 has two AES reference connections labeled ‘AES REF1’ and ‘AES REF2’, as shown
in Figure 2-13. Both connections are shared by the primary control card and the secondary control
card. (See Control Cards

on page 21.) The AES reference connections are “redundant” and use the
same reference type. When both reference connections are connected, if one reference fails, the
control card automatically fails-over to the redundant reference.

Synchronous AES input cards can work with inputs that are not locked to a common AES refer­ence. These inputs are treated as non-synchronous AES signals. Although possible, this is not rec­ommended for high-quality program audio feeds because the audible effects may be unpredictable,
depending on the program content and the degree of offset in the incoming data rate.

on page 68.)

An AES reference is required when using synchronous AES output cards. (See AES Synchronous
on page 23.) While it is possible to let the clock generator on the control card free-run, the synchro­nous AES outputs may contain ticks and pops, the severity of which depends on the difference in
clock rate.

The AES reference connection requires a stable signal source of AES with a sample rate of 48kHz.

If a video reference is present, signals switch at the defined frame and line switch points. If a video

Redundant and Dual References

There are two video reference connections. The same reference can be used for both connections or
a different reference for each connection. When using the same, or “redundant,” references for both
connections, if one reference fails, the control card automatically fails-over to the redundant refer­ence. When using different references, or “dual” references, routing switch takes can be configured

“Redundant” or “dual” mode is selected using UniConfig. If “dual” is selected, each output can be
configured individually to use ‘VIDEO REF 1’ or ‘VIDEO REF 2’ as the reference. For more

connections for external monitoring is provided. See Making Alarm Connections

In addition to an alarm connection, the router control system receives status information from the
router’s control card(s). The control cards read the status of the router’s power supply and fans
through the ‘Power Supply Alarm’ connection. The information is then communicated to the router
control system and is viewable using UniConfig. For more information, see the UniConfig User’s

on page 44.

The router has two control cards (EM0374), one primary and one secondary (optional for redun­dancy). A control card receives commands from the router control system, and in turn, controls the
input and output cards. In addition, the control card manages reference signals, supplies appropriate
timing and control signals to the input cards and output cards, and sends alarm signals to the router
control system.

Both the primary control card and the secondary control card receive router control system com­mands, but only the primary control card actively sends commands to the output cards. Because
both cards receive router control system commands, if the active (primary) control card fails, the
back-up (secondary) control card automatically takes over processing without interruption. In addi­tion, the primary control card and secondary control card communicate with each other. Should
either control card fail, the now active control card communicates the failure to the router control
system.

There are several jumpers on the control card which must be configured before putting the router
into service. For more information, see Control Card Jumper Settings

The control card receives power from the motherboard and 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 operating normally (Green). For more information, see Indicator LEDs

Systems Clock Generator Card

The systems clock is located on the control card. (See Control Cards on page 21.) This clock is crit­ical and used by all input cards and output cards; if the clock fails, the router cannot route audio sig­nals. As a preventive measure, a secondary control card (optional for redundancy) can be installed
to act as a backup should the primary control card fail. If you do not want to install two control
cards, an optional Systems Clock Generator card (EM0414) can be installed in place of the second­ary control card. The Systems Clock Generator card ensures that in the event of a primary control
card failure the system continues to receive clock information. However, the Systems Clock Gener­ator card only provides clock information and cannot take over control card tasks.

Audio I/O Cards

Audio input cards and output cards support AES synchronous, AES asynchronous, and analog
audio signals. Each type of signal requires a unique type of card. For example, to support AES syn­chronous signals, cards that specifically manage AES synchronous signals must be installed. Dif­ferent types of audio input cards and output cards can be inter-mixed in a single frame to meet
specific switching configuration needs.

For each input card and output card installed, an associated backplane must also be installed. For
more information, see Backplanes

Analog and AES synchronous signals may be converted between analog and digital within the
NV5128 router frame. (See Mixing Analog and Digital
chronous signals may be routed as stereo or mono signals, but not as AES asynchronous signals.
AES asynchronous signals can only be routed as stereo signals. However, using the SRC input
card, asynchronous AES signals can be converted to synchronous signals and then routed as stereo
or mono signals. (See AES Sample Rate Converter (Input Only)

The following is a list of the different audio input cards and output cards available. Each card is
listed by the type of signal it manages. For your convenience, the part number for each card has
been included.

Card Power and Fuses

Analog audio and AES input cards and output cards receive power from the motherboard. Each
card uses direct current converters (DC/DC) to convert the corresponding backplane’s +48
into the appropriate regulated supply voltage(s). The combination of pre-regulators and DC/DC
converters and supply voltages varies from card type to card type, depending on the requirements
of the associated circuitry. There is a non-serviceable, self-resetting 1A fuse located on each card.

Status Reporting

All audio input cards and output cards feature a circuit that performs status reporting and drives the
card’s functions. Two LEDs on the front of the card indicate the card’s status: alarm (Red), power
good (Green). Unique to the analog input card, three additional LEDs situated further back on the
card indicate if software is loaded (Amber), and if there is good communication with the control
card (Green) or bad communication with the control card (Red). For more information, see Indica-

tor LEDs on page 76.

The functions of each type of card are described in the proceeding sections. Cards are listed by the
signal type supported.

AES Synchronous

Incoming and outgoing AES synchronous signals, balanced or unbalanced, are received or distrib­uted through passive connectors housed on backplanes: 16 BNC connectors for unbalanced signals
or 16 Phoenix connectors for balanced signals. (See Backplanes

Input Card

The AES synchronous input (EM0389) receives up to 16 stereo signals through passive backplane
I/O connectors. Each signal is routed as an AES signal and is transformer coupled and forwarded to
a receiver. At that time, the signal is synchronized to the system clock; adding and dropping sam­ples as needed until the signal is synchronized.

on page 13.)

The receiver forwards the signal to a buffer, which in turns sends the signal to the motherboard and
onward to output cards for switching.

Note Near-synchronous operation may cause minor disturbances in the audio signal.

These effects are usually masked by the program audio, depending on the sample
rate offset or magnitude and timing of the disturbance.

Output Card

The AES synchronous output card (EM0390) receives up to 128 stereo inputs from the mother­board. The signals are sent to receivers and then to a crosspoint array (128 inputs x 16 outputs ste­reo; 256 inputs x 32 outputs mono) for switching. The crosspoint splits the AES signal into a right
channel, a left channel, and channel status bits for switching as mono signals. Each mono channel
is then recombined with another mono channel to create a new AES signal. The outgoing AES sig­nals are switched synchronously and sent to drivers and backplane I/O connectors for distribution.

Figure 2-17 shows the synchronous AES signal path.

AES Asynchronous

Incoming and outgoing AES asynchronous signals are received or distributed through passive con­nectors housed on backplanes: 16 BNC connectors for unbalanced signals or 16 Phoenix connec­tors for balanced signals. (See Backplanes
routed only to asynchronous AES output cards; they cannot be routed to analog or AES synchro­nous output cards, nor can they be routed as mono channels.

Asynchronous AES operation is not intended for use with “live” or program audio feeds where
glitches at switch boundaries are unacceptable. Instead, asynchronous input cards and output cards
provide an economical way to select AES signal sources, even ones that are synchronous, for ongo­ing operations such as editing, monitoring or dubbing.

Input Card

The AES asynchronous input card (EM0387) receives up to 16 stereo signals through backplane
I/O connectors. The architecture of the input card is identical to that of the AES synchronous input
card, except that signals are not synchronized to the systems clock on the control card. (See AES

Synchronous on page 23.)

Output Card

The AES asynchronous output card (EM0388) receives up to 128 stereo inputs from the mother­board. The signals are then sent to a crosspoint array (128 inputs x 16 outputs) for switching. The
outgoing AES signals are switched asynchronously (i.e., not synchronous with a system clock) and
then sent to balanced output drivers and backplane I/O connectors for distribution. Be aware that
this may cause possible problems in the output signal stream.

AES Sample Rate Converter (Input Only)

The AES Sample Rate Converter (SRC) input card (EM0500) provides additional routing flexibil­ity. The card accepts up to 16 asynchronous AES inputs with a wide range of sample rates. The sig­nals are converted into synchronous AES signals locked to the 48
before being forwarded to the motherboard. This means that a wide variety of AES-compatible dig­ital audio inputs with sample rates from 22

kHz to 108 kHz can be integrated into a synchronous

AES environment or converted to analog audio outputs as desired.

The receivers buffer the input, extracting audio data, sample clock, and applicable channel status
information. The clock and data signals are then processed by an asynchronous SRC and the rate­converted data reformatted and combined with the appropriate channel status information and user
bits. Reference clock signals from the control card are used to synchronize the data to create an
AES format signal. The signal is then forwarded to the motherboard for distribution to output cards.

Analog Audio

The analog audio input card and output card feature DIP switches and a jumper that allow gain and
mute detection to be set. (See Analog Audio Switches
DIP switch set, the operating level of the card can be set to match the operating level of the facility.
By matching the incoming signal level, there is less degradation of the signal when it is converted
to digital for internal routing in the router. For information on setting analog input card levels, see

Analog Audio Switches

on page 69.

Input Card

The analog audio input card (

EM0585) receives up to 16 stereo signals (32 mono channels) through

passive backplane I/O connectors. Inputs are forwarded to an analog-to-digital (A/D) converter.
The A/D converter accepts two analog signals, either left and right channels of a stereo pair or two
mono channels. The A/D converter is rate locked to the systems clock on the control card, convert­ing the signals to a sample rate of 48

kHz and into AES compatible bit streams containing the sam-

pled data. The audio data is set to a common sample point, which is important for proper phase
alignment of audio signals. The resulting synchronous AES signals are sent to the motherboard.

Output

The analog audio output card (EM0586) receives 128 stereo inputs from the motherboard. The sig­nals are then sent to a crosspoint array of 128 inputs x 16 outputs (256 inputs x 32 outputs mono)
for switching and then on to a digital-to-analog (D/A) converter which converts the signal from
digital format to analog. From the D/A converters, the analog signals have low-pass filtering and
gain correction applied and then forwarded to output cable drivers and backplane I/O connectors
for distribution.

Note The analog audio output card is designed to function in a voltage-matched system

driving high impedance loads. The output drivers are not designed to drive 600
loads continuously and may overheat if used in a 600

Video I/O Cards

Video input cards and output cards support the routing of SD, SWB, and analog video signals. Each
type of signal requires a unique type of card. For example, to support SWB signals, SWB input
cards and SWB output cards must be installed. Different types of input cards and output cards can
be inter-mixed in a single frame to meet specific switching configuration needs.

The output card does not need to match the signal type of the input card, but must be able to route
compatible signals. For example, if an analog video input card is installed it can be paired with an
analog video output card.

For each input card and output card installed, an associated backplane must also be installed. For
more information, see Backplanes

There are two unique sets of input cards and output cards that support SWB signals: Classic SWB
card sets and Standard SWB cards. Both types of cards receive, switch and distribute SWB signals.
The two sets of cards differ in the switching configuration each supports. The Classic SWB card set
can be used individually for a 16 inputs x 16 outputs switching configuration, or coupled with
another Classic SWB card set to create a 32 inputs x 32 outputs switching matrix. For details, see

Active Cards

Each card is listed by the type of signal it manages. For your convenience, the part number for each
card has been included. For a list of all video input cards and output cards and their associated
backplanes, see Cards, Card Sets, and Backplanes

Card Power and Fuses

Each input card and output card uses direct current converters (DC/DC) to convert the correspond­ing backplane’s +48

VDC into the appropriate regulated supply voltage(s). The combination of pre-

regulators and DC/DC converters and supply voltages varies from module type to module type,
depending on the requirements of the associated circuitry. There is a non-serviceable, self-resetting
1A fuse located on each module.

Status Reporting

All video input cards and output cards feature a circuit that performs status reporting and drives the
card’s functions. Two LEDs on the front of the card indicate the card’s status: alarm (Red), power
good (Green). Three additional LEDs on the output cards, situated further back on the card, indicate
the card is “healthy” (Amber) and that good communication (Green) or bad communication (Red)
exists. For more information, see Indicator LEDs

The functions of each type of card are described in the proceeding sections. Cards are listed by the

Standard Definition

Incoming and outgoing SD signals are received and distributed through 16 BNC connectors,
housed on a backplane. The backplane for SD incoming signals is active and unique to SD signals.

cable drivers that feed the signal to the input card. On the input card, the SD signal is buffered to
compensate for any loss accumulated as the signal is forwarded to the motherboard and the output
card.

Output Card

The SD output card (EM0384) receives up to 16 SD signals from the motherboard. A bus receiver
feeds the signals to a crosspoint array (128 inputs x 16 outputs) for switching. From the crosspoint,
the SD signal is forwarded to a re-clocker, which automatically switches between 143, 177, and
270

cable driver, which forwards the signal to passive backplane I/O connectors for distribution.

planes: one for inputs (EM0396) and one for outputs (EM0424).

There is a jumper that configures the Classic SWB card set for DVB/ASI operation. For more infor­mation, see Configuration

on page 67.

A single Classic SWB card set can switch 16 inputs x 16 outputs. Two card sets can be linked
together such that the inputs from each card set is sent to the other card set, to create a switching
configuration of 32 inputs x 32 outputs. For more information, see Switching Configurations
page 8.

Up to 16 incoming signals are received through connectors on an associated I/O backplane. Equal­izers on the backplane automatically compensate for length of cable. (See Technical Details
page 83.) The equalized signal is forwarded to the card set and a crosspoint array (32 inputs x 16
outputs) for switching. From the crosspoint, the SWB signal is forwarded to a re-clocker, which
automatically switches between 143, 177, 270, 360, and 540
rates. If the sample rate is non-standard, the re-clockers pass the signal to the backplane for distri­bution without attempting to re-clock it. The signal is then sent to a cable driver on the backplane,
which forwards the signal to backplane I/O connectors for distribution.

There are three types of Standard SWB cards: an input card, a main output card and expansion out­put cards. Depending on how the cards are combined, different switching configurations can be

Input Cards

The Standard SWB input card (EM0466) receives 16 SWB signals through the active backplane
connectors. Equalizers on the backplane automatically compensate for length of cable. (See Techni-

cal Details on page 83.) The equalized signal is forwarded to the input card. The input card buffers

the equalized incoming signals from the backplane and forwards the signal to the motherboard.

Output Cards

There are two Standard SWB output cards: a main output card (EM0463) and an expansion output
card (EM0465). The main output card has a “wing” that extends into the three slots to the right of
the slot occupied by the main part of the card, using all four output slots on the side of the frame in
which it is installed. (See Figure 2-23 on page 29.) Connectors on the wing mate with up to three
optional expansion output cards, installed to the right of the main Standard SWB card.

The Standard SWB main output card receives all 128 available SWB sources from the mother­board. Two 64 inputs x 64 outputs crosspoint arrays on the main output card can switch up to 128
inputs x 64 outputs. From the crosspoint, 16 outputs are re-clocked and sent to the main card’s cor­responding active backplane through connections to the motherboard. The crosspoint forwards the
remaining 48 outputs to the wing connector, which feeds the signals to any installed expansion out­put cards. When installed, the expansion output cards are connected to the wing connector, the
motherboard and associated backplanes.

Analog Video Converter

The Analog Video Converter (AVC) input card and output card add versatility to the NV5128
Multi-Format Router by converting signals, as follows:

• The AVC input card converts incoming composite analog video signals (NTSC or PAL) to SD,
serially-interfaced signals.

• The AVC output card accepts SD inputs from the motherboard and outputs them as analog com­posite signals in NTSC or PAL format.

An AVC input card can be paired with an AVC output card, SD output card or SWB output card.
An AVC output card can be paired with an AVC input card, SD input card or SWB input card. Any
video I/O card paired with an AVC input card or AVC output card must be able to manage a signal
rate of 270

Mb/s.

Converting a signal from analog to SD delays the signal by approximately 1-1/4 lines; frame syn­chronization and sub-carrier phase alignment are not maintained with respect to reference. AVC
input cards and output cards provide an economical way to convert NTSC/PAL inputs where signal

timing is not critical; there is a processing delay of approximately 4 pixels when using an AVC out­put card. With AVC output cards, frame synchronization and sub-carrier phase alignment are not
maintained with respect to reference. This timing is not adjustable.

Incoming and outgoing analog video signals are received or distributed through 16 BNC connec­tors housed on a backplane. (See Backplanes

AVC Input Card

The AVC input card (

EM0432) receives up to 16 composite analog video signals through backplane

I/O connectors. Each incoming signal is received by a differential input amplifier. The amplifiers
create single-ended outputs. The outputs are forwarded to anti-aliasing filters and then onward for
processing by an NTSC decoder (AVC) synchronized to 27
a SMPTE 259M formatter and bus driver. A 27
converter, reduces jitter during the data formatting process. The SD output is line-locked to the
incoming composite signal.The signals is then forwarded to the motherboard for distribution to a
SD output card (EM0384) or to an AVC output card (EM0433).

AVC Output Card

The AVC output card (EM0433) receives up to 16 SD signals from the motherboard. Differential
inputs from the motherboard are buffered by receivers on the output card. The signals are fed to a
128 inputs x 16 outputs crosspoint array for switching. Each of the 16 outputs is re-clocked and
deserialized. The signals are then encoded as baseband video signals, buffered by an output line
driver and sent to the backplane as composite analog.

Machine Control Signals

The NV5128 supports machine control signals, either EIA-232 or EIA-422. Machine control sig­nals are used to communicate between two machines, such as editing equipment and a tape
machines. This enables control of two machines through a single interface.

The Machine Control card set (EM0482) is composed of two cards and occupies two slots in the
router. The Machine Control card set receives 32 signals through two passive backplanes, each con­taining 16 RJ-45 connectors. (See Backplanes

on page 13.)

NV5128 Multi-Format Router • User’s Guide 31

2. Introduction

Active Cards

The Machine Control card set differs from other modules in that it is bi-directional. A Machine
Control card set is neither an “input” nor an “output” card; it carries signals in both directions. The
architecture of the Machine Control card set is similar to the Classic SWB card set: the port card set
occupies two slots and uses two backplanes supporting up to 32 signals. (See Classic SWB
page 28.) Two card sets can be linked together, cross-coupling the inputs from each card set to the
other card set, creating 64 ports. For more information, see Switching Configurations

The port card set has one jumper used to configure the card set to function as a standalone 32-port
card set regardless of where it is installed in the frame. This means that two 32 inputs x 32 inputs
matrixes can be installed instead of one 64 inputs x 64 inputs matrix. For more information, see

Configuration

Incoming and outgoing signals are buffered by differential transmitters and receivers on the card
set. When two Machine Control card sets are connected, signals are sent directly to the 64 inputs x
32 outputs crosspoint array on each card set for switching (creating a 64 inputs x 64 outputs switch­ing matrix) without going through the motherboard.

Figure 2-26 shows the signal flow path through a pair of Machine Control card sets.

Time Code Signals

The NV5128 supports SMPTE time code signals. A time code is a sequence of numeric codes gen­erated at regular intervals by a timing system. Time codes are usually used to synchronize a variety
of signals to a specific start and end time, without regard to any other timing device. For example, a
production plant may use a time code signal to which all signals distributed within the plant are
synchronized. This ensures synchronization of signals to a single “master” clock instead of individ­ual equipment clocks.

Input Card

The time code input card (EM0408) receives 16 time code signals through 16 Phoenix connectors
housed on a backplane. (See Backplanes
code input signals from the input backplane. The receivers send the single-ended outputs to Low
Voltage Differential Signal (LVDS) buffers and then to the motherboard. The signal format on the
motherboard is differential.

Output Card (EM0409)

The time code output card (EM0409) receives up to 16 inputs from the motherboard. Differential
receivers buffer the inputs and forward them to a 128 inputs x 16 outputs crosspoint array for
switching. The time code outputs are reformatted to comply with SMPTE standards and then sent to
the output backplane through time code signal differential line drivers.

Summary

When setting up the NV5128 for the first time or reconfiguring a NV5128, 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 Connecting

the Router to Power on page 38.

3 Install backplanes in the appropriate rear backplane slots. If reconfiguring, removed backplanes

and reinstall in the newly desired slots. See Installing Backplanes

4 Install active cards in the appropriate front card slots. If reconfiguring, removed 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

5 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

6 Make connections to signals acting as references for audio and video signals. If reconfiguring,

verify that all necessary reference connections are made for the signals being routed. See Mak-

ing Reference Connections on page 57.

7 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 59.

8 Make permanent or temporary diagnostic connections. Diagnostic connections enable the

router and UniConfig to communicate. This is important when initially configuring the router
and any time the router is reconfigured. See Making Diagnostic Connections

9 Connect the alarm connection on the router to an external indicator. If reconfiguring, skip this

step if alarm connections are still adequate. See Making Alarm Connections

10 Install UniConfig. If reconfiguring, UniConfig does not need to be reinstalled. See the UniCon-

fig User’s Guide.

3. Installation

Rack Mount

Reference audio and video source at the line rate appropriate for your system.

Frame rack suitable for mounting the router and NV6257 power supply.

Depending on the nature of your usage, you will also need an assortment of video and audio cables,
video and audio sources, video monitors, audio monitors, audio meters, small hardware (screws,
nuts, washers), and tools.

The NV5128 is designed to mount in a standard EIA 19” (483 mm) rack.

How to rack mount the router

1 Determine the placement of the router frame in the rack, and the rack in the facility. When plac-

ing the frame and rack, keep in mind the following requirements:

The router requires 8RUs (14

Be sure to locate the rack near an accessible AC source power outlet.

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 If the router was shipped with the PS6000 power supply modules in the frame, remove them to

make the frame lighter for installation.

inches, 355.6 mm) of vertical space.

Important Do not reinstall the PS6000 power supply modules. The modules are installed

after power is connected.

3 If the router was shipped with the active cards (e.g., circuit boards) and fan tray in the frame,

consider removing them to make the frame lighter for installation. If removing active cards, be
sure to note which card was installed in which slot for later reinstallation.

Caution Handle all circuit boards with care. Be sure to use ESD protection and place

the circuit boards in ESD bags or on an ESD surface.

4 Lift the router frame into position and attach the router frame to the front of the rack with the

appropriate screws. Have helpers assist in the installation, or use a jack, to keep the frame
aligned in the rack. Do not use modules or other internal components as hand holds. Place
screws in all frame mounting screw holes.

5 If not already installed, install the fan tray by inserting tray in the fan tray slot, located at the top

when facing the front of the router frame, as shown in Figure 2-3 on page 11. The fan tray is
installed right-side up.

6 Reinstall any previously removed active cards (circuit boards). Be sure to install them in the

correct location. For installation instructions, see Installing Backplanes

Connecting the Router to Power

Connecting the Router to Power

The NV5128 uses the PS6000 power supply module. The NV5128 requires a minimum of one
PS6000 power supply module (plus one optional modules for redundancy). The router requires two
AC power cords.

The NV5128 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 NV5128 has a ‘Power Supply Alarm’ connection, located on the rear of the frame. The con­nection carries alarm and temperature signals to the router. This connection is connected at the
same time the power connections are made.

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 router frame 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.

Making Power Connections

Important! Be sure to connect to AC power before installing PS6000 power supply modules. Con­necting to AC power after PS6000 modules are installed may result in an electric shock.

How to connect the router to a power source

1 Locate the power cords and PS6000 power supply modules.

2 If not already removed, facing the front of the router, remove all PS6000 power supply mod-

ules, as shown in Figure 3-1.

8 Facing the rear of the NV5128, connect the ground lug to ground using a copper wire from 14

to 6 AWG. The ground lug is located in the lower, left-hand corner.

Installing Backplanes

The NV5128 features backplanes that correspond to different signal types. A backplane is a sepa­rate metal plate that contains connectors for receiving or distributing signals for an associated input
card or output card. Backplanes are inserted into empty slots in the back plate on the rear of the
router. Be careful to install backplanes in the correct slot. With the exception of the SWB input
backplane, the SWB output backplane and the SD input backplane, backplanes are passive and con­tain no active circuitry. Backplanes containing active components receive power from the corre­sponding input card or output card installed in the slot the backplane serves.

Figure 3-3 shows the backplanes installed on the rear of the router. For more information about
backplanes, and the type of signal supported, see Backplanes

R

Installing Backplanes

Each backplane must have a corresponding input card or output card installed in the associated slot.
For example, if a backplane for receiving SD signals is installed, a corresponding SD input card
must be installed in the associated card slot. Typically, for each backplane installed to receive a spe­cific type of signal, a corresponding backplane is installed that distributes the same type of signal.
For more information, see Installing Active Cards

on page 44.

Caution Although different backplanes may appear to be identical (e.g., contain the same

type of connectors), some have active components while others do not. Always
verify that the correct backplane is being for the associated front-loaded active
input card or output card.

Installing Classic SWB Backplanes

Classic SWB backplanes contain 16 BNC connectors and must be installed in specific slots. Install
these backplanes first. Before installing Classic SWB backplanes, review Rules for Classic SWB

Card Sets on page 46.

When installing Classic SWB backplanes in the frame, the silk-screened slot designations on the
rear of the frame are incorrect. To remedy this, a thin plate with the correct I/O designations is
included with the Classic SWB backplanes. This plate should be installed on top of the existing leg­ends.

Each Classic SWB card set requires two backplanes: One is a 16-input active backplane; it includes
automatic cable equalization circuits for the 16 inputs. The other is an output backplane with active
line drivers for the 16 outputs. One Classic SWB card set supports 16 inputs x 16 outputs.

How to install a Classic SWB backplane

1 Facing the rear of the router, locate the legend plate, as shown in Figure 3-4.

Installing Machine Control Backplanes

The Machine Control card set requires two backplanes. If you are installing a single Machine Con­trol card set, the two backplanes may be located in any two adjacent slots associated with the
Machine Control card set. If you are installing two Machine Control card sets (64-port configura­tion), the two backplanes must be installed in specific slots.

Miranda offers an optional connector breakout panel that can be used to convert up to 64 RJ-45
connectors on the router backplane to 9-pin subminiature D connectors (DE9). This breakout panel
occupies 4RUs and hinges open for easy access and to facilitate cable routing. The DE9 connector
wiring follows SMPTE-defined pin assignment standards. For more information, see Machine Con-

trol Breakout Panel on page 43.

spond to the ports.

You can use any of the RJ-45/DE9 connector pairs on the breakout panel that you wish.

Installing Other Video, Audio and Time-Code Backplanes

After installing any Classic SWB or Machine Control backplanes, you can install any other needed
video, audio or time code backplanes. Install input and output backplanes in their respective loca­tions as defined by your plan for populating the frame. Be careful not to confuse input backplanes
with output backplanes, and make certain that each backplane is installed in the correct slot.

Caution Be sure to cover any unused slots with blank plates. (See Installing Backplanes

on page 40.) Leaving openings in the rear may cause the frame to run warmer
than desired, possibly resulting in reduced reliability.

How to install a backplane

1 Unseat any SD input cards and SD output cards before removing or installing SD backplanes.

All other backplanes may be “hot swapped”.

tion of each backplane. Each backplane must have a corresponding input card
and output card.

The NV5128 router features several active cards that manage incoming signals, forward control
system commands, perform signal switching and distribute 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 eject the card for easy removal. For a

There are many possible ways to populate the NV5128 frame with active cards. Before installing
any cards, make sure that for each input card and output card being installed in a slot, a correspond­ing backplane has been installed on the rear for that slot (see Installing Backplanes

Unlike other active cards, the Classic SWB card set and the Machine Control card set take up two
card slots. Each card set requires two associated backplanes, either for SWB or Machine Control
signals. For a description of each card, see Active Cards

Card Installation Rules

The NV5128 was designed to make installation and expansion easy to perform. Some cards, such
as the control card and analog input card or analog output card, have jumpers or switches for
options. It is recommended that all jumpers and switches be set before placing the router into ser­vice. (See Configuration Tasks to Perform Before Installing Cards

There are some restrictions as to which slots cards can be installed in the NV5128 frame. Slots 11,
12, 13 and 14 are unique. (See Figure 2-3 on page 11.) These slots have inter-slot connectors that
allow signals to be passed between cards installed in these slots. This communication is necessary
for proper functioning of the Classic SWB card set and the Machine Control card set. The proceed­ing sections outline card and card set installation rules.

on page 47.)

Rules for Partitions and Card Installation

When installing or reconfiguring input cards and output cards in the router frame, it is important to
keep in mind how partitions for the router control system are created. Some third-party control sys­tems require contiguous partitions, that is, that signal types are grouped together and placed in spe­cific sequence in the router frame.

If using an NV9000 router control system partitions do not need to be contiguous. Using the “vir­tual level” feature in the NV9000, signal types can be organized into different levels, no matter
where the active cards are installed in the frame. For more information, see the NV9000 User’s
Guide.

If using a third-party router control system, active cards should be installed such that physical parti­tions are contiguous. This helps ensure maximum compatibility. If you are unsure about future
router control system applications, configuring the frame with contiguous physical partitions is the
best choice.

Rules for Standard SWB Cards

Standard SWB input cards (EM0466) may be installed in any input slot in the frame. There are two
types of Standard SWB output cards: main (EM0463) and expansion (EM0465). The main output
card occupies four slots in the router frame: one for the main output card with a “wing” and three
slots for optional expansion cards that mate with the wing on the main card. For more information
on card functions, see Standard SWB

When installing four or fewer standard SWB input cards, it is recommended that the cards be
installed in the right-hand input slots in the frame, beginning with slot 12 and working backwards.
This leaves room for installation of the standard SWB output cards. If your switching configuration
requires 64 SWB outputs or fewer, install the standard SWB main output card (EM0463) in slot 13.
Use slots 14, 15, and 16 for additional standard SWB expansion output cards (EM0465). If more

than 64 outputs are desired, begin by installing input cards and output cards on the left side of the
router frame, when facing the front of the router, beginning with the first slots. (See Figure 2-3 on

Rules for Classic SWB Card Sets

Classic SWB card sets (EM0395) occupy two slots each. One card set serves as a SWB video
16×16 output crosspoint array. Two classic SWB card sets can be combined to create a 32×32 out­put crosspoint array. For more information on card functions, see Classic SWB
more information on switching configurations, see Switching Configurations

Each Classic SWB card set requires two backplanes: One is a 16-input active backplane; it includes
automatic cable equalization circuits for the 16 inputs. The other is an output backplane with active
line drivers for the 16 outputs. For more information, see Backplanes

on page 13.

Classic SWB card set must be installed in specific slots, as follows:

Rules for Machine Control Card Sets

A single machine control card set (EM0482) can be installed in any two adjacent slots to create a
32-port array. However, Miranda recommends that the first 32-port card set and backplane set be
installed in slot 11 and slot 12. If two Machine Control card sets are being combined, to create a 64­port configuration, the card sets must be installed in slots 11 and 12 and in slots 13 and 14, respec­tively. (See Figure 2-3 on page 11.) It is not possible to install two independent 32-port module sets
in separate 32-port partitions. For more information on card functions, see Machine Control Signals
on page 31. For more information on switching configurations, see Switching Configurations

Limitations on Combining Classic SWB and Machine Control Card Sets

There are limitations if both the Classic SWB card set and the machine control card set are installed
in a single frame. It is not possible to install two machine control card sets in a 64-port configura­tion while a classic SWB card set is installed because both use the same slots.

Instructions for making signal connections are listed by signal type in the proceeding sections.

AES Synchronous Signals

The NV5128 can route both balanced and unbalanced AES synchronous signals. Unbalanced sig­nals are received and distributed through BNC connectors. Balanced signals are received and dis­tributed through Phoenix connectors. Both types of connectors are housed on backplanes located on
the rear of the router. Each backplane contains 16 connections labeled ‘1’, ‘2’ and so on up to ‘16’.
The labels correspond to the signal numbers assigned to the signal passing through that connector.
For more information on backplanes, see Backplanes

About Phoenix Connectors

Phoenix terminal blocks accept a stripped (bare) wire 18 AWG or smaller. The connectors plug into
the mating receptacle on the backplane, using friction to hold them in place.

When using Phoenix connectors, be sure that only the bare wire end is captive under the clamp
screw and that there are no stray strands that can cause short circuits or accidental ground connec­tions. Also make sure that the weight of the cable or cable bundle does not cause the connector(s) to
disengage over time. Provide adequate support for the cables 12 to 18 inches from the rear of the
frame.

There are 16 BNC connectors on each backplane for AES unbalanced signals and 16 Phoenix
connectors on each backplane for AES balanced signals.

2 For each input connection, connect using the connector and cable appropriate for the type of

incoming signal:

For AES unbalanced signals, use a BNC connector and 75

For AES balanced signals, use a Phoenix connector and twisted-pair 110

Ω cable.

Ω cable. See About

Phoenix Connectors on page 51.

3 Connect the other end of the cable to the source of the signal.

4 Locate the AES output connections on the rear of the router, as shown in Figure 3-8 on page 51.

5 For each output connection, connect using the connector and cable appropriate for the type of

outgoing signal as described in Step 2.

6 Connect the other end of the cable to the signal destination.

7 Make other signal connections, as needed.

Analog Signals

The NV5128 can manage analog signals. Signals are received and distributed through DB25 con­nections, housed on backplanes. (See Backplanes

Each backplane contains four DB25 connectors. Each connector supports either stereo or mono sig­nals:

•Stereo

• Mono

— 4 channel pairs, for a total of 16 stereo signals per backplane.

— 8 channels, for a total of 32 mono signals per backplane.

The DB25 connectors are labeled ‘1–4 Stereo’, ‘5–8 Stereo’, ‘9–12 Stereo’ and ‘13–16 Stereo’. The
labels correspond to the signal number assigned to the signals passing through that connector.

Analog signals are converted to digital (sample rate of 48kHz) for internal routing. (See Analog

Audio on page 25.) For proper conversion to occur, the system AES reference connection must be

connected. For instructions on connecting the AES reference, see AES Reference

on page 57.

3. Installation

Making Signal Connections

The analog audio output card is designed to function in a voltage-matched system driving high­impedance loads. The output drivers are not designed to drive 600
overheat if used in a 600

Ω environment.

Mono Signals

How the NV5128 switches mono signals is dependent upon the router control system. Before set­ting up analog signals, make sure that the router control system can manage mono signals. All sig­nal number labeling on the router frame refers to stereo signals, not mono signals. In order to
successfully install and implement the receiving and distributing of mono signals, great care should
be taken to avoid confusion. For more information on mono signals and signal number labeling, see

Mono Channels

on page 7.

Gain, Mute Detection and Operating Levels

When receiving and distributing unbalanced analog signals, a drop in level of 6 dB occurs. This is
due to one-half of the input signal being lost when the ‘-’ input is grounded and is normal. Using a
switch located on the analog audio input card, an additional 6
sate for the drop. In addition, mute detection and operating levels can be set, ensuring a clearer
audio signal. For instructions on setting gain, mute detection and operating levels, see Analog

Audio Switches on page 69.

Making Reference Connections

Making Reference Connections

The NV5128 uses reference signals to properly time the switching of signals and to avoid picture
disturbances and undesirable discontinuities in audio and time code signals. The reference signal
inputs are located on the left rear of the frame, as shown in Figure 2-4 on page 12.

AES Reference

The AES reference is used for clock generation and provides a timing reference for AES synchro­nous signals and for the control card’s timing circuits. For optimum audio output, signals must be
clock-locked to the same reference. Input impedance is selected by setting jumper located on the
control card. (See Control Card Jumper Settings

The NV5128 has two AES reference connections labeled ‘AES REF 1’ and ‘AES REF 2’. Both
connections are used by the primary and the secondary (optional for redundancy) control card. This
provides a backup reference source should one of the sources fail. The AES reference connection
requires a stable signal source set at 48
nections, see AES Reference Connections

An AES reference must be connected when using AES synchronous I/O cards. (See Audio I/O

Cards on page 22.) When mixing analog audio and AES signals, an AES reference is not required

because the clock generator on the control card provides all necessary clock signals. However, the
AES reference makes it easier to inter-mix analog and AES audio formats.

The AES reference signals have two self-terminating inputs: one BNC and one Phoenix. Each input
supports either balanced or unbalanced formats, but only one connector can be used at a time for
any given input. The unused connection may not be used as a looping output.

Video Reference

The NV5128 provides timing reference connections for analog video signals. The video reference
requires a stable source of PAL, NTSC or Tri-level sync. The video reference connections are
labeled ‘VIDEO REF 1’ and ‘VIDEO REF 2’. For more information on signal switching when a
reference is or is not present and a detailed description of the video reference connections, see

Video Reference Connections

Each ‘VIDEO REF’ connection can use the same reference source (redundant for backup should
one source fail) or two unique reference sources (dual). For more information, see Redundant and

Dual References on page 19.

Making Router Control System Connections

To manage signal switching in the NV5128, connections need to be created between the router con­trol system, UniConfig and the router. UniConfig is an application installed on external hardware
that manages router configuration and set up tasks. For more information, see the UniConfig User’s
Guide.

Connections are as follows:

• Serial control. Use to connect to third-party router control systems requiring a serial control
connection. (See Serial Router Control Connections

• Ethernet. Use to connect to the NV9000 router control system and to create network connec­tions. (See Ethernet Router Control Connections

• GSC Node Bus. Use to connect to third-party router control systems requiring a GSC Node Bus
connection. (See GSC Node Bus Router Control Connections

on page 61.)

on page 59.)

on page 61.)

The router and the router control system cannot communicate with each other until the port through
which the control system connection is made is initialized. For more information, see the UniCon­fig User’s Guide.

Serial Router Control Connections

Serial router control connections are used to connect a router to the router control system and are
often used for third-party control systems. Although serial connections can be used for the NV9000
control system, it is recommended that an Ethernet connection is used instead. (See Ethernet Router

Control Connections on page 61.)

Serial control connections use SMPTE 207M DE9 connectors and serial (RS-422/489) cable. For a
detailed description of the serial control connections, see Serial Connections

Ethernet Router Control Connections

Ethernet router control connections connect the router to the router control system using Ethernet
connectors. Ethernet connections are helpful if the PC running the router control system is going to
be part of a network. An Ethernet connection is recommended for the NV9000 router control sys­tem. The Ethernet ports are shared by the primary and secondary control cards. For a detailed
description of the Ethernet connections, see Ethernet 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. For more information, see the
UniConfig User’s Guide.

The Ethernet connections use RJ45 connectors and Category 5 Ethernet cable, or better. The Ether­net port is 10/100

BT.

How to make an Ethernet connection to the router control system

5 Connect the other end of the second Ethernet cable to the redundant router control system PC.

GSC Node Bus Router Control Connections

Some third-party router control systems require a GSC Node Bus connection to connect the router
to the router control system. The NV5128 has one GSC Node Bus connection, labeled ‘NODE
BUS’, which is shared by both the primary and secondary control cards. For a detailed description
of the GSC Node Bus connection, see GSC Node Bus Connections

To use the GSC Node Bus connection, an optional module must be installed on each control card.
For details, contact Miranda.

The GSC Node Bus connection can use a loop-through to connect to other routers. Terminate any
unused GSC Node Bus connections using a 75

Making Diagnostic Connections

The diagnostic connections enable the NV5128 to communicate with the UniConfig application.
UniConfig is installed on hardware (e.g., a PC), separate from the router, and is used to perform
system setup tasks, and configure and monitor the router. (See Chapter 4, Configuration
page 67.) For information about using UniConfig, see the UniConfig User’s Guide.

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 serial connec­tions are located on the rear of the router, labeled ‘DIAG’. For a detailed description of the perma­nent diagnostic connections, see Diagnostic Connections

Alarm Indicator Equipment

An external alarm indicator can be created to display visual cues when a failure has occurred on the
router frame. The ‘ALARM’ connection on the rear of the NV5128 uses a DE9 connector. LEDs
can be wired to specific pins on a DE9 connector. Each LED indicates what specific router module
has failed. An “alarm” or ON condition occurs when the connection between an alarm pin and
Alarm_COM (common) opens. The alarm turns OFF when the connection between Alarm_COM
and the alarm pin closes again.

To create an indicator box, connect to the ‘ALARM’ connection using a DE9 female connector,

4. Configuration

Chapter 4 provides configuration instructions for the NV5128. It presents the following topics:

• Introduction

• Setting Jumpers and Switches on Cards and Card Sets

Introduction

Before being placed into service, the NV5128 router needs to be configured for your particular
routing needs, router control system, and settings. 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 UniConfig User’s Guide.

Setting Jumpers and Switches on Cards and Card Sets

Several cards in the NV5128 have jumpers and switches that control optional functions or settings.
Jumpers and switches should be set before putting the cards and router into service.

How to set jumpers

1 Facing the front of the router, locate the card or card set. For a detailed description of each card

and its jumpers, refer to the appropriate topic:

Control Card Jumper Settings

Classic SWB Card Set Jumpers

Standard SWB Jumpers

Machine Control Card Set Jumpers

Analog Audio Switches

Analog Video Conversion (AVC) Card Switches

2 Gently remove the card or card set for which jumpers are being set.

3 On the card, if appropriate, locate each jumper by its label number, placing jumper sleeves as

needed. Descriptions of jumper functions are provided in the proceeding sections, listed by card
name. Jumpers are colored blue.

4 On the card, if appropriate, locate each switch being changed. Using a small, pointed object,

such as a ball point pen, slide the beige switch piece to ‘ON’ or ‘OFF’ as desired.

5 When all jumpers and switches are set, gently slide the card or card set back into place in the

router frame.

Control Card Jumper Settings

The control card(s) (EM0374) contains several jumpers. Each jumper connection is labeled with a
jumper identification number. By default, jumpers are placed in the position most commonly used.
These jumpers must be set before the control card is placed into service.

The following lists each jumper label number, function, and correct setting. Any jumpers not listed
are unused and should be left in the factory position:

Classic SWB Card Set Jumpers

Classic SWB card sets (EM0395) automatically re-clock signals at 177, 270, 360, 540 or 1485 Mb/s.
If the data is at any other rate, the re-clocker automatically bypasses the signal, sending it to the
output without re-clocking it.

Individual output re-clockers on the Classic SWB card set can be selectively disabled and the signal
passed directly to the output. This can be done on an output-by-output basis using the UniConfig
application. For more information, see the UniConfig User’s Guide.

Jumper J21, located near the rear of the output module, under the mezzanine board, can be used to
configure the Classic SWB card set for DVB/ASI operation. The jumper (J21) is labeled DVB/ASI.
The default position is DISABLED, allowing normal SWB operation. When J21 is set to
ENABLED, the re-clockers are configured for DVB/ASI operation. In this mode, the re-clockers
ignore the 177

Mb/s sub-harmonic in the signal thereby re-clocking the signal correctly. When set

to DVB/ASI mode, the output re-clockers work properly with all standard SWB signals except
those at 177

Mb/s.

Standard SWB Jumpers

The SWB output cards (EM0463 and EM0465) each contain two jumpers. One jumper (J30) is
located near the front top edge of the board and is labeled RECLOCKER MODE. When the jumper

68 Rev 2.5 • 24 Sep 09

4. Configuration

Setting Jumpers and Switches on Cards and Card Sets

is in the AUTO position, the output re-clocker automatically re-clocks signals at 177, 270, 360, 540
or 1485

Mb/s. If the data is at any other rate, the re-clocker ignores the jumper setting and automat-

ically bypass the signal, sending it to the output without re-clocking it.

When in AUTO mode, individual output re-clockers on SWB output cards can be selectively dis­abled and the signal passed directly to the output, ignoring the jumper setting. This can be done on
an output-by-output basis using the UniConfig application. For more information, see the UniCon­fig User’s Guide.

When the jumper is in the OFF position, all output re-clockers are bypassed and the signal sent
directly to the output. The primary use of this jumper is for factory testing; it is normally left in the
default AUTO position.

A second jumper (J25) is located above J30 and can be used to allow operation with DVB/ASI sig­nals. The default position is DISABLED, allowing normal SWB operation at all accepted data
rates. When J25 is set to ENABLED, the re-clockers are configured for DVB/ASI operation and
work properly with all standard SWB signals except those at 177

Mb/s.

Machine Control Card Set Jumpers

The Machine Control card set (EM0482) has one jumper (J51). In the lower (default) position, the
card set functions as a 32-port standalone port card set (ports 1-32). If the port card set is plugged
into slot 13, it functions as ports 33-64. A module is usually plugged into slot 13 when another port
module is already plugged into slot 11. If the jumper is placed in the upper position, the port card
set functions as a single standalone 32-port module regardless of where it is installed in the frame.

Analog Audio Switches

Depending on the analog audio source equipment you are using, you might want to change several
setting on the analog audio input card (EM0585) and/or analog output card (EM0586). Options
include:

• Setting the gain of individual channels.

If you are using single-ended inputs, you can double the input level by choosing a +6dB switch
setting for those input channels.

• Activating mute detection.

• Setting operating levels to match facility production levels.

Individual Channel Gain

The analog audio input card (EM0585) has four 8-position DIP switch sets near the center of the
board that allow the gain of each channel to be increased by 6dB
labeled SW1, SW2, SW3, and SW5. (SW4 is elsewhere on the board.) Place the switch in the OFF
position for normal gain (0 dB

). Place the switch in the ON position for a gain of 6 dB. There are 32

switches, one for each channel, 1L, 1R, 2L, 2R, and so on up to 16L and 16R.

These switches affect only input gain. The router output continues to operates with an effective
FSD of +24 dB

(doubled). These switches are

Setting Jumpers and Switches on Cards and Card Sets

Mute Detection

The analog audio input card (EM0585) also has a mute detect enable jumper (J21), labeled ‘MUTE
CONTROL’. When the analog audio input level drops to –78 dB or lower for more than 0.25 per
second, the output sample values are replaced with digital silence. This jumper affects all inputs on
the card globally. The ‘ON’ position activates mute control; the ‘OFF’ position deactivates mute
control.

Operating Levels

Both the analog input card (EM0585) and the analog output card (EM0586) have an additional DIP
switch set that can be used to match the operating level of the facility. For example, if the incoming
signal operating level is +24 dbu, the card can be set to +24 dbu. By matching the incoming signal
level, there is less degradation of the signal when it is converted to digital for internal routing in the
router. Operating levels can be set for +15

Figure 4-2. Analog Audio Output Card Switch Locations

Analog Video Conversion (AVC) Card Switches

The AVC input card (EM0432) receives incoming composite analog video (NTSC or PAL) and
converts the signal to SD format for delivery to the motherboard. The AVC output card (EM0433),
receives SD formatted signals from the motherboard and converts them to composite analog video
outputs in NTSC or PAL formats. Because the color space for SD signals differs from that of com­posite signals, the absence or presence of pedestal in NTSC signals must be accommodated if color
and luminance information is to be maintained. To accommodate these differences, DIP switches

NV5128 Multi-Format Router • User’s Guide 71

4. Configuration

Setting Jumpers and Switches on Cards and Card Sets

are provided to preserve as best as possible the color and luminance integrity of signals processed
using AVC cards.

While composite PAL and NTSC inputs can be applied to and simultaneously routed by the AVC
input card (EM0432), all NTSC signals must be in the same format (NTSC-M or NTSC-J). The 8­position DIP switch (S1) on the AVC input card configures the card to process NTSC signals cor­rectly. If the incoming signals are NTSC-M formatted signals, set DIP Switch S1-1 to ON. The ON
position for S1-1 is determined by the markings on the body of the DIP switch. If the incoming for­mat is NTSC-J (no pedestal), set S1-1 to OFF. The remaining seven switch positions (S1-2 through
S1-8) are not used. Switch S1-1 settings have no effect on PAL signal processing.

There are three 8-position DIP switches on the AVC output card (EM0433), labeled S1, S2 and S3.
Switch S2 is not used. The S1 and S3 switches (labeled ‘USER SETTINGS’) configure each output
for the correct NTSC output format (pedestal or no pedestal).

The AVC input card feeds NTSC signals to the AVC output card. All 16 outputs on each output
card must have pedestal settings that match the pedestal settings on the AVC input card. For exam­ple, if the input card’s S1-1 is set to ON, then the output card’s S1 and S2 must have all 16 switches
set to ON. Refer to the silk screen markings on the AVC output card to identify and set switches to
their proper positions. Do not use markings on the actual switch bodies.

Note Attempting to convert NTSC-M signals to NTSC-J signals or vice versa results in

large Chroma/Luma gain errors.

If signals fed to the AVC output card originate from SD input cards, then each output can be config­ured for pedestal or no pedestal (NTSC-M or NTSC-J) composite outputs. DIP switches S1 and S3
have no effect when handling PAL signals.

5. Operation

Chapter 5 provides operating instructions for the NV5128. It presents the following topics:

• Overview

• NV9000 Router Control System

• Third-Party Router Control Systems

Overview

To use the NV5128 router, you need a router control system. The router control system provides an
interface for the operations and maintenance personnel. Through the router control system, signal
switching can be actively configured, reference inputs selected, partitions for organizing signal
switching created, and certain system functions monitored.

The NV5128 was designed to partner with the NV9000 or NV915 control system. However, the
routers are designed with a certain degree of flexibility and can be used with certain third-party
router control systems. For detailed information on using the NV9000 or NV915 control system,
see the associated User’s Guide. For information on using third-party router control systems, see
the third-party vendor literature and User Guide. You can also contact Miranda for more informa­tion on compatible control systems. (See Technical Support Contact Information

NV9000 Router Control System

on page iii.)

Most facilities require multi-level switching capability (audio follow video, for example) and intui­tive device naming capabilities. The choice of control system dramatically affects how operators
use the NV5128 and the ease with which devices are accessed.

Miranda’s NV9000 and NV915 control systems provide a powerful and flexible approach to con­trolling Miranda equipment and third party equipment. The Miranda control systems are comprised
of software and hardware. The control system application runs on a server and can be loaded on a
primary server alone, or also on a secondary (redundant) server as a fail-over backup. Miranda con­trol panels or third-party systems connected to the server can be used to manage the router and
other network equipment.

Miranda’s NV9000 control system offers the choice of several control surfaces, supports redun­dancy and facilitates easy expansion as routing needs change. The NV9000 control system is also
capable of interfacing with third-party signal routing equipment. Because of the variety of features,
capabilities and limitations of other manufacturers’ equipment, users are urged to work closely with
Miranda’s technical staff and with the supplier of the third-party equipment when integrating it into
an NV9000 control system.

NV5128 Multi-Format Router • User’s Guide 73

5. Operation

Third-Party Router Control Systems

Third-Party Router Control Systems

NV5128 control cards use a default protocol. However, at the timing or ordering, a number of third­party control protocols can be installed upon request.

Miranda provides assistance to users wanting to configure Miranda products to function with third­party control systems. However, because Miranda does not manufacture or warrant control systems
from other vendors, we cannot guarantee overall performance or answer all possible configuration­related 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 Miranda if you are considering using a third-party interface to control an
NV5128 router. (See Technical Support Contact Information

on page iii.)

6. Maintenance

Chapter 6 provides instructions regarding maintenance. It discusses the following topics:

• Routine Maintenance

• Fuse Replacement

• Indicator LEDs

• Air Flow

• Intake Filter Screen Cleaning

• Battery Replacement

• Troubleshooting

• Obtaining Service

Routine Maintenance

The NV5128 requires very little in the way of routine or preventative 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.

You might want to examine the system’s Indicator LEDs
operating normally and to make sure that air flow to the power supply fans is unobstructed.

Caution Only qualified service personnel should perform procedures in this section.

occasionally to ensure that the system is

Periodic Inspection

Periodically inspecting the NV5128 for signs of trouble is the best way to prevent unplanned out­ages. The following items will be helpful when performing this inspection.

Begin the inspection at the front of the frame. Open the door to the router and make these observa­tions.

1 Check the +48VDC LEDs on the front of the PS6000 power supplies. An LED that is off or

very dim in brightness indicates a failed or failing supply.

2 Place your hand lightly across the air intakes on the front of the power supplies. Slight air

movement should be felt, indicating that the internal cooling fans are running. These fans run at
very low speed, so only slight air movement will be noticed. A flashlight may be used to verify
that the fan blades are rotating at the proper speed.

3 Look at each active card and verify that none of the red alarm LEDs are illuminated. Normally,

the green and/or amber LED's should be illuminated. Refer to Indicator LEDs
interpret the LED status indicators.

NV5128 Multi-Format Router • User’s Guide 75

on page 76 to

6. Maintenance

Fuse Replacement

4 Look at the control card(s) and verify that the green and amber LED's are illuminated on the

active controller, and that the green LED is ON for the standby controller (if present). Verify
that the low battery LED is off on one or both control cards. Refer to Indicator LEDs
page 76 for a description of the various LEDs and their meaning.

5 Inspect the air intake filter located inside the door. If the filter is dirty or clogged, refer to the

next section for information on how to clean it.

6 Next, move around to the rear of the matrix frame. Ensure that there are no missing backplane

cover plates. Replace any missing cover plates to ensure proper cooling in the frame.

7 Place a hand near the air exhausts. Strong air pressure should be felt evenly across the entire

opening.

8 Check cable connectors for any sign of unseating.

9 Verify that one or both AC cords are firmly seated at both ends. Make sure that the spring bail

power cord retainers on the rear of the frame are in place.

Fuse Replacement

on

If a problem occurs on a card, the first thing to do is check the fuses.

Fuses are located on each of the router’s active cards. Each card features either a “fast blow” or a
fuse that can be reset (“slow blow”). If the card requires a large amount of power, the fuse is “fast
blow” and must be replaced if blown. If the fuse can be reset, reset the fuse by removing the card
from the frame and letting the card temperature cool down. When the fuse temperature reduces to a
safe operating temperature, the fuse automatically resets itself and the card can be reinstalled. The
following table lists the fuses on each card:

Card or Module Fuse Value

Power supply AC Line Fuse 8 amp, 5 × 20 mm, slow-blow

Control card 1 amp

Crosspoint card 1 amp

Input card 1 amp

Output card 1 amp

Monitor card 1 amp

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.

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.

76 Rev 2.5 • 24 Sep 09

6. Maintenance

Indicator LEDs

Indicator LEDs on 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.

Indicator LEDs on Control Cards

The LEDs on the front of 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 (alarm) Indicates a problem or fault. Check the external reference signals; if this does not

resolve the problem, call Miranda Technical Support (see Technical Support

Contact Information on page iii).

Red (low battery) Indicates the battery needs replacing. See Battery Replacement

Amber (active) Indicates the card is the active control card. On the reserve control card, this LED

should be OFF.

Green (health) Normally ON. Indicates the card is operating normally.

on page 78.

Indicator LEDs on Input and Output Cards

The LEDs on the front of the input and output cards can be monitored to determine whether the
cards are operating normally. The LEDs indicate the following:

LED Indicator Indicator Function

Red (alarm) Normally OFF. If it is lit, it indicates a problem; replace the card or call Miranda

Technical Support.

GREEN (Power) Normally ON. Indicates the card is operating normally and receiving power.

Three additional LEDs situated further back on the output card indicate the following:

LED Indicator Indicator Function

Amber (health) Normally ON. Indicates software has loaded and the card is operating normally.

Green (good
communication)

Red (bad
communication)

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.”

Test Points

All active cards, except the control cards, feature power supply test points located in the same pat­tern along the lower portion of the front edge. This simplifies verification of power supply status.
Test points are provided only for voltages actually present on the module.

The matrix controller also provides front card edge mounted test points. These are in a slightly dif­ferent pattern than the matrix modules, but are clearly labeled for function.

NV5128 Multi-Format Router • User’s Guide 77

6. Maintenance

Air Flow

Air Flow

The NV5128 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 cooling fans is located at the top of the router frame (when viewing
from the front). 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 the tray 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.

Intake Filter Screen Cleaning

The intake filter is located on the front door assembly of the NV5128 Multi-Format Router. To
access the filter open the router door by releasing the two thumbscrew locks. Remove the upper
module brace by loosening the two ¼ turn screws, then slide the filter up and to the right to remove
it. 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, a vacuum cleaner or compressed air may be used for clean­ing purposes. 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 indicator on the control card turns on, 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.

Call

Miranda for replacement battery information. For contact information, see Technical Support

Contact Information on page iii.

78 Rev 2.5 • 24 Sep 09

When you insert the new battery, be careful to observe the correct polarity.

Caution To prevent explosion of the battery and possible equipment damage or harm to

Replacing Modules

Active cards, power supply modules and backplanes can be replaced or reconfigured in the router
frame. Whenever reconfiguring, be sure each active card has the correct corresponding backplane.

Active Cards and Power Supply Modules

All front-loaded active cards and the power supply modules (PS6000) may be removed or installed
with the power on (“hot swapped”). Prior to installing a replacement card, verify that user settings
are configured correctly. Cards that receive and process serial data from the control card will auto­matically configure themselves at power up. If a card appears to be defective, first try re-seating it
in the frame.

Replacing Modules

personnel, be sure the battery is oriented with the correct polarity. Polarity mark­ings are visible on the card’s battery housing.

Caution When removing SWB output cards, be sure to remove the expansion output cards

Backplanes

All but the SWB input and output backplane and the SD input backplane are passive and may be
removed at any time. Use the same cautions as exercised with front-loaded modules. Be sure to
match backplanes to the corresponding front active cards. The backplanes housing BNC connectors
are especially easy to install in the wrong location because they look very similar. However, no
damage will normally occur from an unintentional mismatch.

SWB Input/Output and SD Input Backplanes

Unlike other backplanes, SWB input and output and SD input backplanes contain active circuitry.
Power to these modules is supplied by the associated active card installed in the front. To remove
one of these backplanes, first remove the front associated card containing the power supply cir­cuitry.

Troubleshooting

(EM0465) before attempting to remove the main output card (EM0463). Other­wise, damage to the connector “wing” assembly on the main output card may

Check that the PS6000 is fully seated in the frame.
Reset the PS6000 by reseating it in the frame.
Check that all five green LEDs on the front of the 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 power supply.
Check PS6000 fuses. See Fuse Replacement

Check input and output cable continuity.
Check AES Reference.
Check Video Reference.
Check 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

Technical Support Contact Information on page iii.)

Problems with the AES reference inputs could cause all inputs to operate
intermittently or not at all. Check the quality of the reference signals and their
cable connections.

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 power supply module. Check power test points on
power supply. Voltages at power supply test points may be slightly high in
lightly loaded systems. Replace the power supply if any test points indicate
low voltage.

transferring digital audio from CD and DVD players to amplifiers and TVs. AES/EBU is typically
used to transmit PCM and Dolby Digital 5.1, but is not tied to any sampling rate or audio standard.

Device As the term is used in a NV9000 system, a device is a grouping of input and output ports that define

a logical entity. (The logical entity does not have to be a real entity.) For example, a system might
have 3 levels: video, AES, and time code. A hypothetical device in this system is Camera 1, which

Matrix modules are said to be in physically contiguous slots in an NV5128 frame when both the
inputs and outputs associated with those slots are in numerical sequence. For example, input slots 5
and 6 are physically contiguous because inputs 1-16 and 17-32 are in numerical sequence. In the
same way, output slots 4 and 16 are contiguous because outputs 49-64 (slot 4) and 65-80 (slot 16)
are in numerical sequence.
