Introduction

NV8500 series routers offer a highly flexible switching architecture. A single router can switch
both audio and video signals. NV8500 series routers receive and send audio and video signals
on a single I/O card. The hybrid architecture of the NV8500 routers can disembed audio from its
video inputs, recombine audio from multiple inputs, and re-embed audio at its video outputs.
The NV8500 series routers can also switch MADI channels and embed the channels in video
outputs.

NV8500 series routers, as do all of Grass Valley’s NVISION series routers, employ a fully non­blocking architecture.

The NV8500 series includes these routers:

NV8144

NV8140

NV8280

NV8576

NV8576-Plus

Expanded NV8576-Plus

The matrix sizes represent the number of standard outputs the routers support.

— 144 inputs × 144 outputs, nominally

— 144 inputs × 288 outputs, nominally

— 288 inputs × 576 outputs, nominally

About the NV8500 Series Routers

Each NV8500 series router, with the exception noted, can switch these signal types:

• SDI (SD, HD, and 3Gig)

The router’s 3Gig inputs can also receive HD and SD signals. Similarly, the router’s 3Gig out­puts can also transmit HD and SD signals.

• MADI

The routers receive and transmit MADI signals, but extract the audio from the MADI streams
and perform the switching on the audio signals internally.

• AES async

The NV8140 does not switch AES async at this time.

Introduction

About the NV8500 Series Routers

An NV8500 router can be classified as a standard router or a hybrid router. A router is considered
a hybrid router if it has a hybrid control card. A hybrid control card is required if any I/O card is a
hybrid card. A router is considered a standard router if it has a standard control card. If it has
standard control card(s), it cannot have any hybrid I/O cards.

NV8500 series routers have multiple I/O slots and accept a number of different I/O card types
that support the different signal types listed on the previous page. I/O cards can also be classi­fied as standard or hybrid.

For standard I/O cards, the router passes embedded audio (audio embedded in video signals)
through the router, with the video, unaltered. In contrast, hybrid I/O cards allow the indepen­dent routing of audio and video. This is accomplished by (1) de-embedding audio from a video
stream, (2) re-combining or re-embedding audio in video output, (3) extracting audio from
MADI streams, and (4) re-combining audio in outgoing MADI streams.

This flexible router architecture lets you realize these savings:

• Less facility space and power is needed because one NV8500 series router can perform rout-

ing functions that previously required multiple frames.

• There is considerably less need to power and house separate video/audio de-embedders

and embedders.

• Increased flexibility give you more control over the signals routed.

• You can easily enlarge a switching matrix to meet future needs without investing in multiple

routers, subject to the maximum matrix size of the router.

I/O modules for all NV8500 series router can be “hot swapped.” Hybrid modules have green
labeling for easy differentiation from standard modules.

Standard vs. Hybrid

I/O modules are grouped into two categories: standard or hybrid.

Standard I/O can routes video signals (SDI) with or without embedded audio (up to 16 chan­nels), or audio signals (AES pairs). For routers other than the NV8140, standard input cards have
9 inputs. For the NV8140, standard input cards have 18 inputs

Standard output cards have 18 outputs.

Note: Expanded NV8576-Plus routers are a special case. They comprise 2 router frames that
are interconnected. The bulk of the interconnection is through “expansion output cards.”

Standard expansion output cards have 9 outputs.

Hybrid I/O has video and audio signals on the same card. Disembedder (input) cards have 8
video signals with embedded audio. Embedder (output) cards have 16 video signals with
embedded audio. Embedder expansion output card have 8 video signals with embedded audio.

MADI (a.k.a 3Gig/TDM) input cards have 8 video inputs and 1 MADI input (up to 64 channels).
MADI output cards have 16 video outputs and 2 MADI outputs (56 or 64 channels each). The
video, with embedded audio, of a MADI input card is passed through the router, with its audio
unaltered. MADI expansion output card have 8 video signals and 1 MADI output (56 or 64
channels).

IP gateway input cards receive 8 video inputs from 3 10GE Ethernet ports. IP gateway output
cards transmit 8 video outputs on 3 10GE Ethernet ports. IP gateway cards are presently
restricted in use. They support tieline connections only.

Standard I/O cards and hybrid I/O cards can be inter-mixed in the same router. The router is
considered a hybrid router if at least one of the cards is a hybrid card. A hybrid router requires that
all control cards, crosspoint cards and redundant crosspoint cards also be hybrid.

About the NV8500 Series Routers

Hybrid crosspoint cards and hybrid control cards can be used with both hybrid I/O cards and
standard I/O cards. In contrast, standard crosspoint cards and standard control cards cannot be
used with hybrid I/O cards.

The following 3 illustrations show schematically how signals are routed in a frame with (1) only
standard I/O cards, (2) only hybrid I/O cards, and (3) both standard and hybrid I/O cards installed.

Introduction

Overview of the Routers

Overview of the Routers

NV8500 series routers share common frame features. All I/O cards, crosspoint cards, monitor
cards, and control cards are installed through the frame front. All system connections and back­plane modules are located at the rear of the frame.

The following is an overview of each router. For more information about any modules
mentioned, see the related topic:

• Inputs and Outputs on page 21

• Crosspoints on page 63

• Monitoring on page 89

• Router Control on page 83

• Power on page 119

Frame Cooling

The routers have one or more fan trays providing forced air cooling through five speed­controlled fans. The fans draw air from the center and front of the router, through its door, and
exhaust it through the rear of the frame.

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 frame. Temperature sensors at the inlet of
each fan increase or decrease the speed of the fan as required. Because the fans rotate only as
needed, fan noise is significantly reduced in partially loaded frames or in environments with
lower ambient temperatures. Maintaining a constant temperature ensures the proper operation
of router circuitry.

In the NV8144, NV8140, and the NV8280 frames, a single fan tray is located at the top of the
chassis. For the NV8576 (and NV8576-Plus) frames, there are two fan trays: one located at the top
and one located at the bottom of the frame. Each fan features two LEDs that indicate whether
the fan is receiving power and whether there is a failure. For more information, see Indicator

LEDs on page 193.

There is a removable air filter located on the inside of the door assembly. It is recommended that
filter maintenance be performed on a regular basis. For more information, see Air Flow
page 197.

Figure 1-4 shows the front of the NV8144 (with the door removed). At the top of the frame is the
fan tray. Directly below the fan tray are card slots. On the far left are 8 output card slots. Directly
to the right of the output cards is a single slot for the monitor card. Near the center of the frame,
to the right of the output cards, are 2 crosspoint card slots. The first slot holds the primary cross­point card. The second slot holds a second, optional 144×144 crosspoint card for redundancy.

To the right of the crosspoint card slots are 16 input card slots. To the right of the input card slots
are 2 additional slots for the primary and secondary control cards. Below the card slots, at the
bottom of the frame, are 2 bays for PS8100 power supply modules.

Introduction

Preparing for Installation

Expanded NV8576-Plus

The expanded NV8576-Plus router comprises two 32RU frames that have the same structure as
the NV8576 frames. Please refer to figures 1-10 and 1-11, preceding, to see NV8576-Plus frame
structure.

Note that the expanded NV8576-Plus, consisting of 2 frames, will require 4 NV8300 power
supply frames, two for each frame.

The NV8576-Plus, of course, will be populated with expansion output cards and backplanes
instead of regular output cards and backplanes. Expansion output cards in one frame connect
to matching expansion output cards in the other frame. An expansion output card in the first
frame must match the expansion output card to which it is connected in the second frame in
type and position. See Expansion I/O Cards

NV8576-Plus (Stand-Alone)

A stand-alone NV8576-Plus is a single 32RU frame that have the same structure as the NV8576
frame. Please refer to figures 1-10 and 1-11, preceding to see the stand-alone NV8576-Plus
frame structure.

The stand-alone NV8576-Plus requires 2 NV8300 power supply frames.

The stand-alone NV8576-Plus, of course, will be populated with expansion output cards.
Because there is only one frame, expansion cables are not used.

on page 102 for details about matching card types.

Preparing for Installation

Before you set up the router, be sure to review the information in this section.

When your products arrive, immediately inspect the shipping container. If the container is
damaged, unpack and inspect the contents. If the contents are damaged, notify the carrier
immediately.

When unpacking the shipping container, look for the packing slip and compare it against the
contents to verify that everything ordered was received. If anything is missing (or if equipment is
damaged unrelated to shipping), please contact Miranda.

Your shipment does not contain mounting racks, network cables, video cables, mounting
screws, or grounding wire. If you have ordered an NV8280, NV8576, or NV8576-Plus, included in
the shipment will be one or more NV8300 external power supply frames.

Shipments of the NV8576 and NV8576-Plus also include a rack-mounting kit, including a jack,
lifting handles, and instructions.

You will need the following items for installation:

A computer running Windows
required for installing the Miranda Router Configurator and other configuration software.

(Optional) tool for connecting DIN 1.0/2.3 connectors.

Frame rack suitable for mounting the router.

Installation Steps

Installation and (re)configuration tasks should be performed in a specific order to avoid possible
complications.

1 Mount the router.

Before rack-mounting, remove all installed modules to make the router easier to lift into
place. (NV8500 series routers ship with the cards and backplanes installed.)

Before making any connections or installing any modules, the router and other frames
should be mounted in a rack so that the frame remains stable when you are connecting
cables to the frame. See Rack Mount

2 (Re)Install cards and backplanes.

These include I/O cards, monitor cards, I/O backplanes, monitor backplanes, crosspoint
cards, and control cards.

NV8500 series routers ship with the cards and backplanes installed. You might have to
remove the cards and backplanes initially to be able to lift the router into place in its rack.

For information about the modules and installation instructions, see the related section:

• Inputs and Outputs on page 21

• Crosspoints on page 63

• Monitoring on page 89

3 Make control connections.

Router control system connections allow the router and router control system to communi­cate. See Router Control

4 Make expansion connections.

If you installing an NV8576-Plus, make the necessary expansion connections between the
two frames. See Expanded NV8576-Plus

5 Make (optional) alarm connections.

Alarm connections communicate system and power status to external indicators. Use the
system alarm connector on the router frame.

If you are installing an NV8280, NV8576, or NV8576-Plus, you can use the power supply
alarm connectors on the NV8300 power supply frame. (The NV8144 and NV8140 do not use

W BNC connectors.

an external power supply and have their own power supply alarm connectors.) See Alarms
on page 109.

6 Connect to power.

After all other modules are installed and connections are made, connect the router to AC
power. The NV8144 and NV8140 connect directly to AC power. The NV8280, NV8576, and
NV8576-Plus frames connect to the external NV8300 power supply frame which connects to
AC power.

Note: be sure to insert PS8300 power supply modules in the NV8300 after all power connec-
tions are made. This is how you turn the router on and off. The PS8300s are hot-swappable.
See Pow

Note: each PS8300 requires a 20A circuit at 110

7 Launch the Miranda Router Configurator.

The Miranda Router Configurator (MRC) is used to configure the router and monitor system
status. MRC should be installed on a PC in the same network as the router control system.
See the Miranda Router Configurator User’s Guide.

er on page 119.

VAC. A 22 0 VAC line requires 10 A circuitry.

NV8500 series router frames are designed to fit in a 19” (482.6 mm) EIA rack. The NV8280, the
NV8576, and the NV8576-Plus use one or more NV8300 external power supply frames that also
requires rack-mounting. It is not required that both the router and power supply frames be
mounted in the same rack.

For details about power requirements and how to connect to power, see Pow

Before mounting frames in the rack, determine the placement of the router frame, and if appli­cable, the NV8300 power supply in the rack and the rack in the facility. When placing the frames
and rack keep in mind the following requirements:

er on page 119.

• Vertical space for the router frame:

NV8144 frames occupy 8 RUs.

NV8140 frames occupy 8 RUs.

NV8280 frames occupy 16 RUs.

NV8576 frames occupy 32 RUs.

Stand-alone NV8576-Plus frames occupy 32 RUs.

Each of the two frames of an expanded NV8576-Plus occupies 32 RUs.

• Vertical space for the NV8300 power supply frame:

The NV8144 and the NV8140 do not use external power supply frames.

For an NV8280, only one power supply frame is required, totalling 3 RUs.

For an NV8576 or a stand-alone NV8576-Plus, two power supply frames are required total­ling 6 RUs.

For an expanded NV8576-Plus, four power supply frames are required totalling 12 RUs.

• Vertical space for NV8900 MADI Interfaces, each of which requires 1 RU. See NV8900 MADI

Interfaces on page 54. (NV8900s are optional.)

Note: Grass Valley’s NV8900 interfaces can concentrate AES signals in a MADI stream for con­nection to a MADI input or extract AES signals from a MADI output. For details, see NV8900

18

MADI Interfaces on page 54. Future MADI interfaces to analog audio are planned.

• AC power connects directly to the NV8144 frame and to the NV8140 frame. AC power con-

nects to the NV8300 power supply frame used for the other NV8500 routers. The NV8144
requires a 15A circuit for each connection. The NV8140 requires a 20A circuit for each con­nection. The NV8300 requires a 20A circuit for each of its power supply modules in 110 VAC
environments. (There are 4 modules in each NV8300 power supply frame.)

In 220 VAC environments, a 10A circuit is required for NV8300 power supplies.

• If you are installing an expanded NV8576-Plus (two frames), the frames must be located near

each other, side-by-side or back to back, so that you can make expansion connections
between the frames. The distance between the frames is limited by the length of expansion
cables (4 meters). See Connecting the NV8576-Plus Frames

• To ensure proper cooling, leave space for unrestricted air flow through the front of the

router, and a minimum of 6-inches of clearance at the rear where the cooling fans exhaust
warm air.

• Allow space for cabling to the router’s I/O connectors.

To Rack Mount the Router

NV8500 Series

User’s Guide

on page 104.

1 Temporarily place the router frame near the rack in which it is to be installed.

2 Remove the front door by turning its retaining screws counter clockwise, opening the door,

and lifting it free of its hinges.

Important: never use the front door handle to lift the frame.

3 The router was shipped with control cards, crosspoint cards, I/O cards, I/O backplanes, and

fan trays installed. Remove them to make the frame lighter for installation. If you do remove
the 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 electrostatic discharge (ESD) protec­tion and place the circuit boards in ESD bags or on an ESD surface. Do not stack boards
without ESD protection.

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

appropriate screws. Be sure to place screws in all frame mounting screw holes.

CAUTION

An equipment jack or two persons are required to lift and install the router frame. The
router frame is considered too heavy for one person to lift and install in the rack.

Note: NV8576 frames are shipped with a rack-mounting kit, including a jack, a shelf for sup­porting the frame while it is still not secured with screws, handles for lifting the frame into
place, and instructions for rack-mounting using the kit. An NV8576-Plus is also shipped with
the rack-mounting kit. An NV8280 frame is shipped with a handle for lifting it into place.

5 Reinstall the fan trays in the fan tray bays. The fan tray openings face the interior of the

router. In the NV8576 and NV8576-Plus frames, the openings of the upper fan tray face down
and the openings in the lower fan tray face up.

Introduction

Rack Mount

6 Reinstall control cards, crosspoint cards, I/O cards, I/O backplanes, monitor cards, and moni-

tor backplanes. Be sure to install them in the correct location. The router was configured at
the factory with the cards in a specific location. If you install I/O cards in a different location,
the router will have to be reconfigured before it can run properly.

7 If you are using NV8300 power supplies, perform the following steps:

a If the NV8300 was shipped with the PS8300 power supply modules in the frame, remove

the modules.

CAUTION

Do not re-insert the PS8300 power supply modules until after you have made all
power connections. For more information, see
page 126.

b Lift the power supply frame into position and attach the power supply frame to the front

of the rack with the appropriate screws. Place screws in all frame mounting screw holes.

c Repeat steps a and b for additional power supply frames.

8 Re-mount the front door.

9 Wait until you have completed all installation tasks before you reinstall PS8300 power supply

modules, powering up the router. (See Connecting to Power

Connecting to Power on

on page 126.)

20

I/O modules include input cards, output cards, and their backplanes. Input cards receive
incoming signals through connectors on their backplanes and forward them to crosspoint
cards. The crosspoint cards route the signals, as directed by the control card, to output cards.
The signals are then distributed from the output card through connectors on their backplanes.

For a comprehensive list of I/O modules and corresponding backplanes with part numbers, see

Part Numbers

on page 213.

Expansion cards are applicable only to the NV8576-Plus expanded router. (The NV8576-Plus
expanded routers do not accept IP gateway output cards. No expansion IP gateway output
cards exist yet.)

The expansion output cards all have two inter-frame connections, in addition to their output
connectors.

The “special functions” of the disembedder/embedder cards are (1) null audio and (2) pass­through audio. See N

Backplanes

Backplane modules have signal connectors of 3 types, in general:

• Coax (DIN 1.0/2.3)

• Fiber optic (IP gateway cards, having SFP connector modules housing LC connectors)

See Backplanes Having SFP Modules

• WECO quick-release connectors (5-pin or 3-pin, for twisted pair wiring).

• M3 connectors. See M3 Cards on page 185.

Expansion backplanes, used for the NV8576-Plus only, have additional expansion connectors.

For routers other than the NV8140, input backplanes have 9 connectors. For the NV8140, input
backplanes have 18 connectors.

For routers other than the NV8140, frame sync input backplanes have 9 connectors and an addi­tional RJ-45 (Ethernet) connector for configuring frame sync functions. Frame sync cards and
backplanes are not available for the NV8140.

All output backplanes have 18 connectors. All expansion output backplanes have 9 output
connectors and two inter-frame connectors.

Backplanes with Coax Connectors

These backplane modules have coax (Din 1.0/2.3) connectors:

The coax backplanes are used for standard I/O, disembedder cards, embedder cards, MADI cards
(a.k.a, TDM cards), and AES async cards.

Generally, the coax input backplanes have 9 ports. The output backplanes have 18 ports. The
expansion output card has 9 ports and two 28-pin expansion connectors.

The frame sync input backplane has an additional Ethernet port for the configuration of the
frame sync card.

When these backplanes are used with hybrid I/O cards, one or two of the ports remain unused.

The M3 output backplane module is unique. It has a single 16-port “M3” connector supporting

Fig. 2-1: I/O Backplane Modules As Used for Hybrid I/O

The fiber and WECO backplanes have the same port numbering method as the coax backplanes.

Note that the coax backplanes used for hybrid cards are also used for standard cards. If, for
example, you exchange a standard card for a hybrid card in a particular slot, it is not necessary to
change the backplane, as long as the card is a coax-compatible card.

The video ports of frame sync input backplane modules follow the same pattern as for the
disembedder backplane modules.

The NV8140 is the only router in the NV8500 family that uses 18-connector disembedder (input)
backplanes and 18-connector MADI (3Gig/TDM) input backplanes. (Frame sync input back­planes are not available for the NV8140.)

Signal Numbering

When you are facing the rear of the router frame, where signal connections are made, signal
numbers are assigned, in increasing order, from top-to-bottom and from right-to-left.

This is true even in the NV8576 and NV8576-Plus where I/O cards and their backplanes in the
lower bays are rotated 180° from those in the upper bays.

See Figure 2-2, following.

Fig. 2-2: Connector Ordering

Also, for the NV8576 and NV8576-Plus, slot numbers increase right-to-left, in sections. The
sections are disjoint (non-contiguous). See Slot Order for Port Numbering

on page 37.

For standard routers, each input and output connector has a unique signal number assigned to
it. For standard video cards, and AES async cards, port numbering is straightforward: each
connector supports one video signal or one AES pair, as the case may be.

For hybrid routers, there are two numbering sequences, one for video signals and one for audio
signals. Keep this in mind when working with hybrid I/O cards that support both video and
audio. For hybrid video and audio, a single connector represents multiple inputs (or outputs).
Signal numbering is more complex.

However, hybrid routers do not have circuitry for all the port numbers in their port space.

Each video port and each AES async port is an element of the router’s crosspoint matrix.

Hybrid audio ports are elements of a hybrid router’s TDM audio switching “matrix.”

Each I/O card also has an I/O port space within the port space of the router:

The port numbers assigned to cards in successive slots increment by the numbers in this table.

However, hybrid cards do not have circuitry for all the port numbers in their port space.

Embedder and Disembedder Cards

For all NV8500 routers except the NV8140, a (hybrid) disembedder card has only 8 video ports.
Each of the 8 carries 16 embedded audio channels (or audio ports) for a total of 128 audio ports.
The 9th video port and the 16 audio ports it would have do not exist. Therefore, the 9th
connector on the disembedder card’s backplane goes unused.

That is true for the frame sync input cards and backplanes, which are essentially disembedder
cards whose backplanes have an additional RJ-45 port.

For the NV8140, a (hybrid) disembedder card has 16 video ports. Each of the 16 carries 16
embedded audio channels (or audio ports) for a total of 256 audio ports. The 9th and 18th video
ports and the 16 audio ports each of those ports would have do not exist. The 9th and 18th
connector on the card’s backplane go unused.

A (hybrid) embedder card and a (hybrid) disembedder/embedder card each have 16 video ports.
The 9th and 18th video ports and the 16 audio ports each of those ports would have do not
exist. The 9th and 18th connector on the card’s backplane go unused.

Nevertheless, nonexistent video and audio ports and their unused connectors are counted in
the port numbering.

Similarly, an embedder expansion output card has only 8 video ports. The 9th video port and
the 16 audio ports it would have do not exist. Therefore, the 9th connector of its backplane is
unused:

Audio port ordering for frame sync input cards is the same as for disembedder cards.

MADI Cards

For all NV8500 routers except the NV8140, a MADI (i.e., 3Gig/TDM) input card has 8 video ports
and 1 MADI input; the 9th connector of its backplane is for MADI, up to 64 channels. For these
cards, only 64 audio ports of the 144 in the card’s space exist.

For the NV8140, a MADI (i.e., 3Gig/TDM) input card has 16 video ports and 2 MADI inputs. The
9th and 18th connectors of its backplane carry MADI, up to 64 channels for each connector. For
these cards, only 128 audio ports of the 288 ports in the card’s space exist.

A MADI (3Gig/TDM) output card has 16 video ports and 2 MADI outputs. The 9th and 18th

The range of ports for any IP gateway output card is the same as for the embedder card.
However, only the first 8 ports are used; the other ports (9–18) are ignored (at this revision of the

Port Ordering

Port ordering is a function of slot ordering. The slots of an NV8140, NV8144, or NV8280 are
ordered from right-to-left, as labeled at the rear of the router. However, for the NV8576 frames
and NV8576-Plus frames, there are two orderings: one labels the slots on the router in right-to­left order (from 1 to 32 and from 33 to 64). The other slot ordering, that pertains to port
ordering, is a different ordering. See Slot Order for Port Numbering

Because video and audio port numbering for hybrid I/O is complex, Grass Valley has released
several reference documents that enumerate the router’s port numbers exhaustively for stan­dard I/O, disembedder and embedder I/O, and 3Gig/TDM (MADI) I/O. This table lists the
available reference documents:

We recommend that you obtain a copy of these documents. Contact Miranda Customer Service.

Standard I/O

Standard I/O cards support 3Gig, HD, SD, and AES async signal types.

For all NV8500 routers except the NV8140, standard input cards accept 9 signals, either video or
AES pairs, depending on the card type.

For the NV8140, standard input cards accept 18 video signals. (The NV8140 does not support
AES async.)

Standard output cards transmit 18 signals, either video or AES pairs, depending on the card
type.

Standard expansion output cards, used for the NV8576-Plus only, transmit 9 signals, either video
or AES pairs, depending on the card type. Expansion output cards have, additionally, 2 expan­sion connectors for cabling between the two frames of the NV8576-Plus.

Embedded audio, when it present, is passed through the router, with its video, unmodified.

Hybrid I/O

All hybrid cards support 3Gig, HD, and SD video rates.

Disembedder Input

For the NV8140

The hybrid disembedder card can disembed 16 audio channels from each of its 16 video inputs.
Each disembedder card thus has 256 audio inputs. However, input backplanes used for disem­bedder cards have 18 connectors. Sixteen of the connectors are used for the video and two

Inputs and Outputs

Types of Input and Output

connectors — the 9th and the 18th — are unused. Nevertheless, the unused connectors are
counted in the port numbering sequence as if they were additional video inputs with 16
embedded audio channels.

The router’s port numbering scheme associates 16 audio port numbers with each video port.
Video port 1 carries audio ports 1–16, video port 2 carries audio ports 17–32, and so on.

This numbering applies to a disembedder card in any slot. A disembedder card in slot 1 provides
video ports 1–16 and audio channels 1–128 and 145–272. The 9th and 18th connectors are
unused and the corresponding ports (video ports 9 and 18 and audio ports 129–144 and 273–

288) do not exist. Thus, a disembedder card in slot 2 supports video ports 19–26 and 28–35 and
audio channels 289–416 and 433 –560. Its 9th and 18th connectors are also not used. A disem­bedder card in slot 3 supports video ports 37–44 and 46–53 and audio channels 577–704 and
721–833, and so on.

Consecutive disembedder cards increment by 18 video ports and 288 audio channels. Consecu­tive cards follow the slot ordering for port numbers. See Slot Order for Port Numbering
page 37.

For Other Routers

For all NV8500 routers except the NV8140, the hybrid disembedder card can disembed 16 audio
channels from each of its 8 video inputs. Each disembedder card thus has 128 audio inputs.
However, input backplanes used for disembedder cards have 9 connectors. Eight of the connec­tors are used for the video and the 9th connector is unused. Nevertheless, the 9th connector is
counted in the port numbering sequence as if it were another video input with 16 embedded
audio channels.

(Frame sync input cards (and backplanes) can be considered disembedder cards that have an
additional RJ-45 port for configuring frame sync functions.)

The router’s port numbering scheme associates 16 audio port numbers with each video port.
Video port 1 carries audio ports 1–16, video port 2 carries audio ports 17–32, and so on.

This numbering applies to a disembedder card in any slot. A disembedder card in slot 1 provides
video ports 1–8 and audio channels 1–128. The 9th connector is unused and the corresponding
ports (video port 9 and audio ports 129–144) do not exist. Thus, a disembedder card in slot 2
supports video ports 10–17 and audio channels 145 through 272. Its 9th connector is not used.
A disembedder card in slot 3 supports video ports 19–26 and audio channels 289–416, and so
on.

Consecutive disembedder cards increment by 18 video ports and 288 audio channels. Consecu­tive cards follow the slot ordering for port numbers. See Slot Order for Port Numbering

ports 129–144 and 273–288) do not exist. Thus, a card in slot 2 supports video ports 19–26 and
28–35 and audio channels 289–416 and 433 –560. Its 9th and 18th connectors are also not used.
A card in slot 3 supports video ports 37–44 and 46–53 and audio channels 577–704 and 721–
833, and so on.

Consecutive embedder or disembedder/embedder cards increment by 18 video ports and 288
audio channels. Consecutive cards follow the slot ordering for port numbers. See Slot Order for

Port Numbering on page 37.

The numbering scheme for hybrid expansion embedder output cards and disembedder/
embedder output cards (used by the expanded NV8576-Plus only) is like the numbering scheme
for disembedder input cards. (Expansion embedder output cards and disembedder/embedder
output cards have 8 outputs.)

Differences

Disembedder/embedder output cards differ from embedder output cards because the disem­bedder/embedder cards support what is called pass-through audio. See Pass-Through Audio
page 76.

IP Gateway Cards

IP gateway input cards receive up to 8 video streams over 3 10GE Ethernet connections. IP
gateway output cards transmit up to 8 video streams over 3 10GE Ethernet connections.

Video streams are mapped into to the router port numbering using the IP gateway card’s
internal browser application.

The IP gateway input card, aside from the fact that it has SFP connectors and receives patck­etized video, is in fact a disembedding input card and its ports, having been mapped into the
port space of the router, can be configured as can any disembedder port.

The range of ports for any IP gateway input card is the same as for the disembedder cards. See
Figure 2-3.

The IP gateway output card, similarly, is an embedding output card and its ports, having been
mapped into the port space of the router, can be configured as can any embedder port.

The range of ports for any IP gateway output card is the same as for the embedder card.
However, only the first 8 ports are used; the other ports (9–18) are ignored (at this revision of the
IP card). Again, see Figure 2-3.

There are no IP gateway input cards for the NV8140. There are no IP gateway expansion output
cards (for the NV8576-Plus).

 At present, IP gateway cards, input or output, can be used only for tielines.

See Chapter 11, IP Gateway C

ards, for details.

Inputs and Outputs

Types of Input and Output

3Gig/TDM Input

For the NV8140

The 3Gig/TDM (i.e., MADI) input card supports 16 video signals and 2 separate MADI streams. If
the video has embedded audio, it is not disembedded, but passed through the router. Each
MADI input can receive up to 64 audio channels.

The router’s port numbering scheme associates 128 audio port numbers with a card.

This numbering applies to a MADI input card in any slot.

The input backplane supports the 16 video signals on 16 of its connectors and the MADI
streams on its 9th and 18th connectors.

A MADI input card in slot 1 provides audio ports 1–128 and video ports 1–16. The card in slot 2
provides audio ports 289–352 and video ports 19–26, and so on. Other audio channels in the
“space” of the card do not exist.

Consecutive MADI input cards increment by 18 video ports and 288 audio channels. Consecu­tive cards follow the slot ordering for port numbers. Slot Order for Port Numbering

For Other Routers

The 3Gig/TDM (i.e., MADI) input card supports 8 video signals and a separate MADI stream. If the
video has embedded audio, it is not disembedded, but passed through the router. Each MADI
input can receive up to 64 audio channels.

The router’s port numbering scheme associates 64 audio port numbers with a card, unlike the
disembedder/embedder cards which associate audio ports with video ports.

This numbering applies to a MADI input card in any slot.

The input backplane supports the 8 video signals on 8 of its connectors and the MADI stream on
its 9th connector.

Thus, a MADI input card in slot 1 provides audio ports 1–64 and video ports 1–8. The card in slot
2 provides audio ports 145–208 and video ports 10–17, and so on. Other audio channels in the
“space” of the card do not exist.

Consecutive MADI input cards increment by 9 video ports and 144 audio channels. Consecutive
cards follow the slot ordering for port numbers. Slot Order for Port Numbering

3Gig/TDM Output

The 3Gig/TDM (i.e., MADI) output cards support 16 video signals and 2 MADI streams. The video
might have embedded audio, but it will have been passed through the router with the video.
Each MADI output can transmit 56 or 64 audio channels, switch-selectable.

The router’s port numbering scheme associates 128 audio port numbers with a card, unlike the
disembedder/ cards which associate audio ports with video ports.

This numbering applies to a MADI output card in any slot.

The output backplane supports the 16 video signals on 16 of its connectors and the 2 MADI
streams on its 9th and 18th connectors.

A 3Gig/TDM output card in slot 1 provides video ports 1–8 and 10–17 and audio channels 1–64
and 145–208. For this card, other audio channels do not exist.

Thus, a MADI output card in slot 2 supports video ports 19–26 and 28–35 and audio channels
289–352 and 433–496. A 3Gig/TDM card in slot 3 supports video ports 37–44 and 46–53 and

NV8500 Series

User’s Guide

audio channels 577–640 and 721–784, and so on. Other audio channels in the “space” of the
card do not exist.

Consecutive MADI output cards increment by 18 video ports and 288 audio channels. Consecu­tive cards follow the slot ordering for port numbers. Slot Order for Port Numbering

on page 37.

The number scheme for MADI expansion output cards (used by the expanded NV8576-Plus
only) is like the numbering scheme for MADI input cards. (MADI expansion output cards have 8
video outputs and 1 MADI outputs.)

Embedded Group Control

An NV8500 router can force embedded audio channels to be null. If all 4 channels of an
embedded audio group are null, the group is null too. That is,

If a single channel is null, the output’s embedder inserts silence for that channel.

If all 4 channels of an audio group are null, the embedder will omit the group from its outgoing
data stream.

Routing null sources to an output is under operator control (or under control of automation).

Two conditions are required for the router to be able to do this:

• In MRC, you must define a “null audio source” for the router’s synchronous audio level.

• An operator must perform takes of the designated null source(s) to the selected audio chan-

nels of the intended destination.

A “null audio source” can be any of the inputs in a synchronous audio partition of the router. It is
recommended that you use a port number of one of a disembedder card’s unused video ports
(one where the video port number is a multiple of 9).

Nothing of the audio port’s signal is used. The “null audio source” is an artifice that tells router
firmware to handle the destination’s targeted audio channel(s) in a certain way.

A port designated as the “null audio source” cannot also be used as a normal audio source.

 The use of embedded group control is not compatible with DHP.

 If a null source is routed to a MADI output, the take is rejected.

 Only NV8500 hybrid routers at v3.1.2 and later support embedded group control.

 In MRC, router levels that are not ‘Synchronous Audio’ do not support null audio sources. In

the ‘Router Levels’ page of MRC, the ‘Null Audio Source’ field for these levels is not enabled.

 Whether an audio channel is null is a factor in the logic of disembedder/embedder output

cards.

Slot Numbering

Slot Numbering

Physical slot ordering is primarily right-to-left (as you face the rear of the router.)

For the NV8576 frame and the NV8576-Plus frame, there is a different slot ordering for port
numbers.

Physical Slot Ordering

When you face the rear of the router, the slots are numbered incrementally from right-to-left.

• NV8144

Slot numbers increment from right-to-left:

• NV8140

Slot numbers increment from right-to-left:

• NV8280

Slot numbers increment from right-to-left.

• NV8576, NV8576-Plus

Slot numbers increment from right-to-left in each bay:

The slots are numbered from 1 to 64, both for inputs and for outputs.

For the NV8576-Plus, slots in both frames have this same numbering.

User’s Guide

The labels on the rear of the NV8576 and NV8576-Plus frames reflect this numbering. How-
ever, slots are ordered differently with respect to port numbering.

Slot Order for Port Numbering

Port numbers increase with consecutive slots in the ordering for port numbers.

NV8140, NV8144 or NV820

Port numbering for the NV8140, NV8144, and the NV8280 follows the physical slot numbers.

NV8576

Slot ordering (for ports) for the NV8576 follows the ordering1 shown in figures 2-5 and 2-6. An
NV8576 has 64 output slots (32 upper and 32 lower) and 64 input slots (32 upper and 32 lower).

This is the ordering of slots for input port numbering, as viewed from the rear:

Fig. 2-8: NV8576-Plus Slot Order for Output Port Numbering

The video port ordering is the same for frame 2 of an expanded NV8576-Plus, but the video port
numbering ranges from 577 to 1152 instead of from 1 to 576.

I/O Backplanes

Signals are received and distributed through backplanes installed in the rear of the router frame.
For proper operation, each backplane must match its corresponding input card or output card.
That means a coax backplane must match a coax I/O card and a fiber optic backplane must
match a fiber optic I/O card.

However, a coax input backplane can match a standard input card (video or AES), a disem­bedder card, or a 3Gig/TDM (MADI) card, as long as the card is also designated “coax.”

Standard and hybrid I/O cards can use the same backplanes for similar signals.

Fiber optic cards and backplanes are not used for hybrid I/O.

backplanes.

Fig. 2-9: I/O Backplanes

Note that backplanes using DIN 1.0/2.3 or WECO connectors are passive; backplanes using SFP
(fiber optic) connectors have active circuitry.

Installing I/O Backplanes

Routers are delivered with all backplane modules installed. However, at some point you may
need to change backplanes. Before doing so, consult with Grass Valley Technical Support to
ensure proper operation.

To maintain proper airflow for cooling, all backplane slots must have either a backplane or cover
plate installed.

To Install an I/O Backplane

1 Facing the rear of the router, locate the slot into which the backplane is being installed.

2 Insert the backplane into the frame being sure to align the backplane’s printed circuit board

with the guides in the frame. Use gentle pressure at the top of the backplane to ensure the
backplane connector is fully mated with the motherboard.

Fig. 2-13: SFP Connectors

Interchangeable SFP modules fit in SFP cages on the backplane modules. The standard SFP
module has 2 ports that operate at 1310 nanometers. These are receivers on the input back­plane modules, or transmitters on the output and expansion output backplane modules.

The output and expansion output backplane modules can also accept SFP modules whose
ports have differing wavelengths. When a backplane module is populated with such SFP
modules, it can support connection to one or more CWDM multiplexers. The CWDM multi­plexers accept up to 18 fiber-optic signals. The signals must each have a different wavelength.
The range of wavelengths accepted is 1271

SFP Modules in NV8576 Frames

Because output cards in the lower bays of the NV8576 frames are rotated 180° with respect to
the output cards in the upper bays, the orientation of SFP modules in the lower bays is likewise

Persons who connect SFP modules to CWDM multiplexers should be aware of the difference in
orientation.

Figure 2-14 also shows a suggested ordering for the SFP wavelengths. It is not the only ordering
possible, but it has the advantage of being uniform and identical in both orientations. A fiber­optic backplane module thus populated can be used in either the upper or lower bays.

SFP Modules in NV8280, NV8140, and NV8144 Frames

The SFP modules for these routers are oriented as shown in Figure 2-14 for the upper bays.

In addition, the ports of fiber-optic output backplanes are numbered as shown in Figure 2-14.

Different types of input cards and output cards can be inter-mixed in a single frame. For each I/O
card installed, a corresponding backplane must also be installed. (See I/O Backplanes
page 39.)

All input cards and output cards have a circuit that reports status (to the router’s control card)
and drives the card’s functions. LEDs on the front of the card also indicate the card’s status. See

AES Async

AES async cards are standard cards, not hybrid.

AES async signals are AES pairs (normally stereo pairs). In NV8500 series routers, they do not
require an AES reference signal.

For instructions on making AES reference connections, see Audio and Video References
page 60.

 The NV8140 does not support AES async.

Input

The AES async input card receives up to 9 balanced or unbalanced signals through local I/O
connectors: DIN 1.0/2.3, for unbalanced signals or WECO, for balanced signals. An incoming
signal can be distributed to any or all AES outputs.

Each input card has 9 AES receivers. The AES receiver distributes the signal to the motherboard.
The motherboard forwards the signal to the crosspoint cards for distribution to output cards.
The input card also sends its signals to a monitor selector for forwarding to the monitor card.
(See Monitoring

on page 89.)

Output

The AES async output card receives 18 signals from the crosspoint card (via the motherboard).
The card contains 18 transmitters. Each transmitter creates 2 copies of the outgoing signal,
feeding one copy to a connector and one copy to a monitor selector. The monitor selector sends

The following diagram shows the flow through AES async I/O cards. The crosspoint card uses its
crosspoint matrix for routing AES signals to AES output cards. The TDM matrix (shown for refer­ence) is used only for hybrid audio signals.

Fig. 2-16: AES Async Signal Flow

HD or 3Gig (Standard)

Standard 3Gig I/O cards are available in coax or fiber versions.

Standard HD cards are available in coax versions only.

Video signals require a video reference for proper switching. See Making Reference Connections
on page 61.

Any embedded audio signals are passed, unmodified, through the router to output.

Reclockers on the output card may be turned “on” or “off” using the Miscellaneous Settings
page in MRC. Reclockers are only available for coax signals, not for fiber optic signals. For more
information, see the Miranda Router Configurator User’s Guide.

Input

For all NV8500 routers except the NV8140, the standard HD input card and the standard 3Gig
input card can receive 9 video signals. For the NV8140, the standard 3Gig input card can receive
18 video signals.

Ports on the HD card can receive either SD or HD; ports on the 3Gig card can receive SD, HD, or
3Gig. Each card has a cable equalizer for each port that distributes the signal to the mother­board. The motherboard forwards the signal to the crosspoint cards for distribution to output
cards. An incoming signal can be distributed to any or all video outputs, except that 3Gig signals
cannot be routed to HD outputs. The card also distributes the signal to a monitor selector for
forwarding to a monitor card. (See Monitoring

on page 89.)

Output

Ports of the standard HD output card accept either SD or HD; ports of the 3Gig output card
accept SD, HD, or 3Gig signals. Each output card receives 18 signals from a crosspoint card (via
the motherboard). Each of the 18 ports has a re-clocker. The re-clocker creates two copies of the
signal, feeding one copy to a cable driver and one copy to a monitor selector. The cable driver

Hybrid (3Gig)

on page 89.)

Note: Most hybrid cards require coax connectors. They do not use fiber backplanes. The excep­tion are the IP gateway cards which use SFP (fiber) backplanes.

With 3Gig hybrid I/O cards, the router can switch embedded audio channels independently.

Hybrid cards in this classification are the disembedder (input) card, the embedder (output) card,
and the disembedder/embedder (output) card. For NV8500 routers other than the NV8140, a
disembedder card has 8 disembedders, one for each video input. For the NV8140, a disem­bedder card has 16 disembedders, one for each video input.

An embedder output card and a disembedder/embedder output card each have 16 embedders,
one for each output.

A disembedder on an input card extracts the embedded audio from its video stream. The audio
is then forwarded to the TDM audio “matrix” for routing.

Frame sync input card can be considered disembedder cards that have an additional RJ-45 port
for configuring frame sync functions.

IP gateway input cards can be considered disembedder cards that have an additional RJ-45 port
for configuring IP functions. IP gateway output cards can be considered embedder cards that
have an additional RJ-45 port for configuring IP functions. The input cards relay incoming video
streams to the 8 ports of the card. The output cards packetize the 8 video ports of the card into
video streams that are transmitted on the SFP connectors of the card.

Embedders on an output card re-integrate audio signals from up to 16 sources into the
outgoing video stream.

The disembedder/embedder output card has a disembedder and 16 audio multiplexers, in addi­tion to the embedder, for each output. Router logic can select for each audio channel of each
output one of the following sources: (1) the equivalent audio channel from the video at the
output, (2) generated silence, or (3) audio from other sources, via the TDM audio matrix.

If a disembedder detects a Dolby E pair in its video stream, the disembedder instantly phase­aligns the channel pair. Long-term phase alignment is provided for all other channels. If the

50

NV8500 Series

User’s Guide

Dolby E signal is off-rate, the router adds or drops samples in the Dolby E guard band to main­tain Dolby signal integrity.

Hybrid I/O cards require the installation of hybrid control cards and hybrid crosspoint cards in
the router.

Embedder State for Embedder Output Cards

Embedders can receive video and audio from a standard video input card. In such a case, the
embedder card passes the video and audio unmodified through to output, bypassing the
embedder for that output. In such a case, we say the embedder is “off.”

However, when the embedder receives audio from (one or more) audio sources such as a disem­bedder card or a MADI input card, the embedder passes the audio from the TDM matrix to the
embedder which multiplexes the different audio streams into its video output. In this case, we
say the embedder is “on.”

The router turns an output’s embedder on or off automatically according to switching rules. (See

Switching Rules

MRC).

When the “force” attribute is ON, the output’s embedder is forced on.

When the “force” attribute is “Use Switching Rules,” the output’s embedder is not forced, but left
in its automatically generated state.

Note: This attribute is specified in MRC’s ‘Input Attributes’ page.

Note: if your router uses DHP, the setting for all inputs should be “Use Switching Rules.”

on page 80). However, every input has a “force” attribute (that can be set in

State of Disembedder/Embedder Output Cards

The disembedder/embedder output card has a disembedder and 16 audio multiplexers, in addi­tion to the embedder, for each output. Router logic can select for each audio channel of each
output one of the following sources: (1) the equivalent audio channel from the video at the
output, (2) generated silence, or (3) audio from other sources, via the TDM audio matrix.

Each multiplexer is controlled by its audio channel’s ‘null’ flag and ‘pass-through’ flag. If the ‘null’
flag is set, the channel is null. The channel carries silence unless all 4 channels in a group are null,
in which case, the entire group is omitted from the output.

If the channel is not null, it receives audio from the same channel of the video at the output if its
pass-through flag is set. Otherwise, it receives audio from another source through the TDM
matrix.

 Embedders of disembedder/embedder output cards are not affected by the “force” attribute

as are the embedders of embedder cards. The embedders of disembedder/embedder cards
are always on.

 The use of pass-through audio is not compatible with DHP. Thus, disembedder/embedder

output cards are not compatible with DHP.

Combining Standard and Hybrid

DHP (dynamic hybrid pathfinding) is an NV9000 service that allows NV8500 series routers to
disembed and embed audio signals in video streams with relatively few hybrid 3Gig cards
installed. With DHP, the router passes standard 3Gig inputs through an internal pool of disem-

DHP allows you to populate the router with several relatively inexpensive standard I/O cards and
just a few hybrid I/O cards and still have the benefits of hybrid routing.

For more information about using DHP, see the

Input

For NV8500 routers other than the NV8140, the hybrid disembedder card and the frame sync
input card receive up to 8 video streams composed of either SD, HD or 3Gig signals.

For the NV8140, the hybrid disembedder card receives up to 16 video streams composed of
either SD, HD or 3Gig signals. (The NV8140 does not have frame sync cards.)

Each stream can carry up to 16 embedded audio channels for a total of 128 audio channels or, in
the case of the NV8140, up to 256 audio channels.

Each video stream is forwarded to a cable equalizer and then to a disembedder. The card auto­matically detects whether the video format has embedded audio. Embedded audio channels
are forwarded to an audio TDM MUX and then to the motherboard for distribution to the cross­point cards. Similarly, the video signals are forwarded to the motherboard, which distributes the
signals to the crosspoint cards.

With the exception of the NV8140, the input card also distributes one signal to a monitor
selector for distribution to a monitor card. (See Monitoring

Output of Embedder Cards

The hybrid embedder card receives 16 video signals (SD, HD or 3Gig) from the crosspoint cards
(via the motherboard). It accepts 256 audio signals from the TDM matrix. The card has 16
embedders. Each embedder embeds 16 audio (AES or Dolby E) channels from multiple sources
into a video stream. The embedder then forwards the output to a reclocker. The card’s reclockers
sends one copy of each signal to the monitor selector and another copy to the cable drivers, ulti­mately to the output connectors. Except in the NV8140, the monitor selector is 16×1 MUX that
sends its output to a monitor card. The NV8140 does support monitoring. (See Monitoring
page 89.)

Note: Hybrid embedder cards mute during a control card fail-over.

Note: It is possible in MRC to cause the reclockers on the output card either to be used or to

be bypassed individually for each output of the router. These attributes are specified in the
‘Output Attributes’ page of MRC.

The following diagram shows the flow of a signal through hybrid embedder cards. Video signals
are routed through the crosspoint matrix. Audio signals are routed through the TDM matrix.

Output of Disembedder/Embedder Cards

The disembedder/embedder card receives 16 video signals (SD, HD or 3Gig) from the crosspoint
cards (via the motherboard). It accepts audio signals from the TDM matrix. The card has 16
embedders. Each embedder embeds 16 audio (AES or Dolby E) channels from multiple sources
into a video stream. The embedder then forwards the output to a reclocker. The card’s reclockers
sends one copy of each signal to the monitor selector and another copy to the cable drivers, ulti­mately to the output connectors. Except in the NV8140, the monitor selector is 16×1 MUX that

on

Fig. 2-19: Block Diagram of Hybrid 3Gig Signal F low

The disembedder/embedder output card has — for each embedder — a disembedder and 16
audio multiplexers. Router logic selects for each audio channel of each output one of the
following sources: (1) the equivalent audio channel from the video at the output, (2) generated
silence, or (3) audio from other sources, via the TDM audio matrix.

Each multiplexer is controlled by its audio channel’s ‘null’ flag and ‘pass-through’ flag. If the ‘null’
flag is set, the channel is null. The channel carries silence unless all 4 channels in a group are null,
in which case, the entire group is omitted from the output.

If the channel is not null, it receives audio either from the same channel of the video at that
output if its pass-through flag is set. Otherwise, it receives audio from another source through
the TDM matrix.

 Note: Hybrid disembedder/embedder cards mute during a control card fail-over.

Hybrid (3Gig/TDM)

For routers other than the NV8140, hybrid 3Gig/TDM input cards receive 8 video stream plus 1
MADI stream. For the NV8140, hybrid 3Gig/TDM input cards receive 16 video stream plus 2 MADI
streams. The input cards accept MADI streams of up to 64 channels. Audio embedded in the
video streams is not disembedded and passes through the router unchanged. The audio chan­nels carried in the MADI stream are routed through the TDM matrix. MADI signals are locked to
48

kHz. (See Audio and Video References on page 60.)

Hybrid 3Gig/TDM output cards (1) receive 24-bit PCM audio with AES channel status (C), user (U)
and validity (V) bits preserved, (2) insert 24-bit silence with valid C, U, V bits on inactive chan­nels, and (3) perform phase alignment of all channels.

53

Inputs and Outputs

I/O Cards

Hybrid I/O cards require the installation of hybrid control cards and hybrid crosspoint cards in
the router. Although the installation of one or more hybrid 3Gig/TDM output cards is recom­mended, it is possible to switch outgoing audio signals from MADI inputs to hybrid embedder
cards.

An NV8900 interface can be used with MADI (3Gig/TDM) cards to convert your facility’s AES
signals or analog audio signals into a MADI stream, or to convert an outgoing MADI stream into
discrete AES signals or analog audio signals.

NV8900 MADI Interfaces

The NV8900 MADI interfaces convert discrete audio signals to MADI and vice versa. There are 6
NV8900 models:

All are 1RU interfaces.

The MADI converters allow you to (1) concentrate discrete audio signals in a MADI stream,
conserving router inputs and outputs, and (2) pass discrete audio signals through a router’s TDM
switching matrix, where they can be re-combined. (Signals on AES async cards are not passed
through the TDM matrix.)

The NV8900 AES-to-MADI converters receive 32 AES pairs and multiplex them into one MADI
stream.

The NV8900 AA-to-MADI converter receives 64 analog signals pairs and multiplexes them into
one MADI stream.

The NV8900 MADI-to-AES converters extracts 32 AES pairs from a MADI stream.

The NV8900 MADI-to-AA converters extracts 64 analog signals from a MADI stream.

Note: the routers can receive and transmit Dolby E as a pair of channels in a MADI stream.

Input

For all NV8500 routers except the NV8140, the 3Gig/TDM input card receives 8 3Gig video
signals (SD, HD or 3Gig) and one MADI stream composed of up to 64 (mono) channels through 9
DIN 1.0/2.3 connectors. Each card has 8 cable equalizers, one for each of the 8 video signals.

For the NV8140, the 3Gig/TDM input card receives 16 3Gig video signals (SD, HD or 3Gig) and 2
MADI streams, each composed of up to 64 (mono) channels through 9 DIN 1.0/2.3 connectors.
Each card has 16 cable equalizers, one for each of the 16 video signals.

Each cable equalizer distributes the video signal to the motherboard. The motherboard
forwards the signal to the hybrid crosspoint cards for distribution to output cards. An incoming
signal can be distributed to any or all hybrid output cards. The card’s video inputs can also be
distributed to any standard output card. The card also distributes a video signal to a monitor
selector for distribution to a monitor card. (See Monitoring

Any embedded audio in the video stream is passed through the router with the video signal.
The audio is not disembedded.

One MADI stream is received though one input connector at a sample rate of 48
samples per second). The router can receive any number of MADI channels (up to 64) in a
stream.

User’s Guide

The MADI input stream can carry Dolby E pairs as well as AES pairs. Because the MADI stream is
locked to your house reference, Dolby E signals coming in faster or slower than the house refer­ence will have samples added or dropped to match your house reference rate.

Each MADI signal is transformer-coupled to remove “noise” and forwarded to a MADI receiver.
The receiver extracts clock and data, removing any unnecessary synchronization information.
The signal is then forwarded to an audio TDM MUX and onward to the motherboard for
forwarding to the crosspoint cards.

Setting the MADI Input Card’s EQ State

You can configure the MADI input card so that it performs equalization (EQ) on the card’s MADI
signals. Normally EQ is enabled. Some installations might, however, require equalization
depending on the length of cables for the video signals. To set the EQ state for MADI input cards:

1 Locate the MADI input card to change.

2 Remove the card from the router frame.

3 Locate DIP switch 4:

4 Using a small, pointed object, such as a ball point pen, slide the switch to ON or OFF to con-

figure the equalization state:

ON

— EQ is disabled.

OFF

— EQ is enabled. (This is the default.)

5 Repeat for other MADI input cards you want to change.

Note that this is not required for MADI output.

Output

The MADI output card receives 16 video signals (SD, HD or 3Gig) from the crosspoint matrix and
up to 128 audio signals from the TDM matrix (via the motherboard) and forwards the signals to
its backplane’s connectors. The audio is multiplexed into two MADI streams, each stream and
the channel within the stream is selected based on the destination of the audio channel.

The output card’s TDM selector combines the audio channels into a single output and then
forwards the output to a MADI transmitter. The transmitter’s cable driver forwards the MADI
signal to its connector.

I/O Cards

The video signals received from the crosspoint card are sent to a reclocker and then a cable
driver for distribution to backplane connectors. Embedded audio in the video streams is passed
through the router with its video.

A copy of the MADI and video signals are sent to a monitor card. (See Monitoring

The following diagrams shows the flow of a signal through MADI I/O cards. The hybrid cross­point card uses a TDM matrix to switch audio signals from hybrid I/O cards. Video signals are
managed by a crosspoint matrix.

IP Gateway Cards

See Chapter 11, IP Gateway Cards.

Installing I/O Cards

I/O cards slide into a (color-coded) card guide. Connectors at the rear of the card mate with
connectors on the motherboard. The ejector lever of each card is color-coded to match the color
of the card guides into which the card is to be inserted.

As you install cards, observe their LEDs:

If the ‘Valid Backplane’ LED on the card lights, the card and the backplane in the same slot match
correctly. You will probably want to verify that the ‘Good COM’ LED is on and the ‘Bad COM’ LED
is off. (For more details about LEDs, Indicator LEDs

on page 193.)

CAUTION

Do not drop, handle roughly, or stack circuit boards. If you cannot easily insert or remove a
board, stop and contact Grass Valley Technical Support.

Making I/O Signal Connections

After backplanes are installed, cables are connected to the I/O connections using one of three
connector types and cables:

• Coax (DIN 1.0/2.3) connectors and Belden 1855A cable (or an equivalent).

• SFP connectors and fiber optic cable.

• WECO connectors and twisted pair cable.

The type of signal determines the backplane connector. Before making signal connections,
review the following:

• Disembedder input cards, embedder output cards, and disembedder/embedder output

cards (coax only)

For NV8500 routers other than the NV8140, the disembedder (input) backplane has 9 video
connectors, of which only the first 8 are used.

For the NV8140, the disembedder (input) backplane has 18 video connectors, of which the
9th and 18th are unused.

The embedder (output) backplane has 18 video connectors, of which the 9th and 18th are
unused.

The expansion output () backplane has 9 video connectors, of which only the first 8 are used.

Each video signal has up to 16 embedded audio channels.

• MADI (3Gig/TDM) cards (coax only)

For NV8500 routers other than the NV8140, the input backplane has 8 video connectors. Its
9th connector receives one MADI stream containing 64 time slots (or channels).

For the NV8140, the input backplane has 16 video connectors and two MADI connectors.
Both MADI connectors (numbered 9 and 18) receive a MADI stream containing 64 time slots
(or channels).

The output backplane has 16 video connectors and two MADI connectors. Both MADI con­nectors (numbered 9 and 18) emit a MADI stream containing either 56 or 64 time slots (or
channels).

The expansion output backplane has 8 video connectors. Its 9th connector emits one MADI
stream containing either 56 or 64 time slots (or channels).

• IP gateway cards

Please refer to Chapter 11, IP Gateway C

• AES async cards (coax or WECO)

AES backplanes have either coax connectors for unbalanced signals or WECO connectors for
balanced signals. Each connector supports one AES pair.(WECO pins are on 3.5 mm centers.)

The input backplane has 9 connectors.

The output backplane has 18 connectors.

The expansion output backplane has 9 output connectors.

 The NV8140 does not support AES async.

• Standard 3Gig fiber optic

Backplanes for fiber optic signals are composed of SFP modules each containing two LC con­nectors. (SFP modules are sold separately.)

Inputs and Outputs

Audio and Video References

For NV8500 routers other than the NV8140, the input backplane has 5 modules for a total of
10 LC connectors. The backplane accepts 9 inputs; the 10th connector is not used.

For the NV8140, the input backplane has 9 modules for a total of 18 LC connectors.

The output backplane has 9 modules for a total of 18 LC connectors.

Like the input backplane, the expansion output backplane has 5 modules for a total of 10 LC
connectors. The backplane emits 9 outputs; the 10th connector is not used.

Audio and Video References

The NV8500 provides both AES (async) and video reference connections. Internal audio clocks
can be either set to an external AES reference or generated by the control card from the video
reference. The references are labeled AES REF and VIDEO REF. References for audio are used in
order of priority, as follows:

AES REF 1
AES REF 2
VIDEO REF 1
VIDEO REF 2
(Internal free-running clock)

AES References

The AES reference is used for clock generation, which provides a timing reference for AES sync
signals, and for timing circuits on the control card. On the rear of the router frames are two AES
reference connections. The primary control card and the secondary control card share the AES
reference.

The AES reference connections are redundant and should use the same reference signal. When
both references are connected, if one reference fails, the control card automatically fails over to
the redundant reference.

AES reference connections require a stable audio signal source set at 48

kHz. See Making Refer-

Video References

Located on the rear of the router, four BNC connectors provide video reference input. If a video
reference is present, signals switch at the defined frame rate and line switch points. If a video
reference is not present, the router still performs the switch, but according to an internal refer­ence. If a video reference is not connected, the control card illuminates its (red) alarm LED. (For
details about LEDs, see Indicator LEDs

Video reference connections require a stable source of PAL, NTSC, or tri-level sync. The control
card uses these references to perform takes at the proper point in time (according to SMPTE
RP168). See Making Reference Connections

on page 193.)

on page 61.

60

Redundant and Dual Video References

The same reference can be used for both reference connections or different references can be
applied at the two connectors. If you apply the same reference, the connection is termed redun­dant. If one reference fails, the control card fails over to the redundant reference.

NV8500 Series

AES Reference Con­nectors

User’s Guide

If you have different references (e.g., NTSC and PAL), or dual references, switches can take place
according to one or the other reference.

You can specify, in MRC, whether your video reference connection is redundant or dual.

(See the Miranda Router Configurator User’s Guide.)

Switch points use references based on priority, as follows:

Crosspoints

The crosspoint cards of the router form the switching matrix of the router.

These are the video matrix sizes for standard routers:

NV8144 144×144

NV8140 144×288

NV8280 288×576

NV8576 576×1152

NV8576-Plus, stand-alone 576×576

NV8576-Plus, expanded 1152×1152.

The router matrix is distributed across one or more crosspoint cards.

Hybrid routers have the same video crosspoint matrix as do standard routers, and additionally a
audio “matrix” for switching synchronous audio. The audio “matrix” can be as large as
18432×18432.

Hybrid I/O does not use the entire port space of the router. Some ports in the space go unused.

The crosspoint card(s) receive signals from input cards and switch the signals to the appropriate
output cards as directed by the router’s control card.

Standard crosspoint cards can be used only with standard I/O cards. Hybrid crosspoint cards can
be used with both hybrid I/O cards and standard I/O cards. If the router has at least one hybrid
card, all crosspoint cards must also be hybrid and the control cards must be hybrid. A frame can
only have one type of crosspoint installed, either all standard or all hybrid.

For a list of crosspoint cards available and their part numbers, see Crosspoint Cards

on page 218.

Overview of Crosspoints

The NV8144 has two slots for crosspoint cards: one active and one stand-by. All signals pass
through the active crosspoint card. The active crosspoint card switches all inputs to all outputs.
The stand-by crosspoint card takes over switching should the active crosspoint card fail.

The NV8140 has 3 slots for crosspoint cards: two primary and one redundant for backup. The
redundant card occupies the middle crosspoint card slot. All signals pass through the active
crosspoint cards. Together, the crosspoint cards switch any input to any output. One of the cros­spoint cards targets the upper 9 outputs of output cards. The other crosspoint card targets the

one of the primary crosspoint cards fail.

 Note that the crosspoint card slots for the NV8140 are narrower than the crosspoint slots for

The NV8280, NV8576, and NV8576-Plus have a slightly different crosspoint architecture because
they are larger routers. Each router has 10 crosspoint slots: 8 for crosspoint cards and 2 for an
optional redundant crosspoint module. The optional redundant crosspoint module acts as a
backup for any of the other 8 crosspoint cards.

Redundant Crosspoint Module

A redundant crosspoint module, if present, can substitute for a failed crosspoint card. Fail-over
to the redundant card can be automatic or manual.

A redundant crosspoint module has one or more function buttons located at the front of the
module. When an operator presses a button, the redundant crosspoint module can be set either
to take over active control from another crosspoint card or to operate in stand-by mode. This is
the button panel of the redundant crosspoint module of an NV8576:

the NV8144. Do not attempt to install the older (and now obsolete) EM0799 or EM0819 cros­spoint cards in the NV8140. Physical damage will result.

64

Each numbered button represents a crosspoint card slot. The brightness of a numbered button
indicates the state of the crosspoint card:

• Off. The button is disabled (while redundant crosspoint is taking over for regular crosspoint).

• Dim. The button is enabled and the corresponding crosspoint is in active mode.

• Bright. The crosspoint is inactive and the redundant crosspoint is substituting for that cross-

point.

The buttons of the redundant crosspoint module for the NV8140 and the NV8280 are similar to
those for the NV8576 pictured above. The NV8144 does not use a special redundant crosspoint
card, but uses a second crosspoint card that functions as a backup.

Automatic Fail-Over

The router’s control card can be configured to cause the redundant crosspoint module to take
over for a failed crosspoint card automatically. Otherwise, an operator can switch the redundant
crosspoint manually. (The manual switch-over can be performed remotely through MRC.)

It is in MRC’s ‘Redundant Crosspoint’ page that automatic switch-over can be configured. If
automatic switch-over is enabled, then the router’s normal crosspoint cards can be prioritized so
that in the rare event that two crosspoints fail at the same time, the redundant crosspoint will
substitute for the crosspoint having the highest priority.

(In the NV8144, there is only one active card, so priority is moot.)

Crosspoint Card Status

The crosspoint cards and the redundant crosspoint module have status reporting circuitry.
Three LEDs on the front of the card or module indicate the card’s status: alarm (red), power is
good (green), card is active (amber). Two other LEDs indicate whether there is good (green) or
bad (red) communication with the control card. For more information, see Indicator LEDs
page 193.

An NV8144 has slots for two crosspoint cards. One crosspoint card is active and the other is
stand-by. Both the active crosspoint card and the stand-by crosspoint card receive all inputs. The
stand-by crosspoint does nothing unless the active crosspoint fails.

The active crosspoint sends its outputs to the output cards. If fail-over is automatic and the
active card fails, the NV8144’s control card causes the stand-by to take over for the active card.
When the stand-by card becomes active, it sends its outputs to the output cards.

Overview of Crosspoints

NV8140

An NV8140 has slots for two normal crosspoint cards and a redundant crosspoint card. Both
crosspoint cards and the redundant crosspoint card receive all inputs. The redundant crosspoint
card is in stand-by mode; it does nothing unless one of the normal crosspoints fails.

The active crosspoint cards send their outputs to the output cards.

If fail-over is automatic and an active card fails, the NV8140’s control card causes the redundant
card to take over for the failed active card. When the redundant card becomes active, it sends its
outputs to the output cards.

The redundant crosspoint is installed in the middle crosspoint slot:

NV8280

In an NV8280, the router’s switching matrix is distributed across 8 crosspoint cards. Each card
switches a specific subset of the inputs or outputs. Crosspoint cards are installed in crosspoint
slots 1–4 and 7–10. The optional redundant crosspoint module is installed in slots 5 and 6:

User’s Guide

Normally, the redundant crosspoint module is in stand-by mode; it does nothing unless one of
the normal crosspoints fails.

If fail-over is automatic and a normal crosspoint card fails, the NV8280’s control card causes the
redundant card to take over for the failed card. When the redundant card becomes active, it
sends its outputs to the output cards normally supported by the failed crosspoint card.

NV8576

In an NV8576, the router’s switching matrix is distributed across 8 crosspoint cards. Each card
switches a specific subset of the inputs or outputs. Crosspoint cards are installed in crosspoint
slots 1–4 and 7–10. The optional redundant crosspoint module is installed in slots 5 and 6:

Overview of Crosspoints

Expanded NV8576-Plus

(See Chapter 6, Expanded NV8576-Plus on page 97, for details of the NV8576-Plus.)

In an NV8576-Plus, the router’s switching matrix is distributed across 8 crosspoint cards in each
of two frames. Crosspoint cards are installed in crosspoint slots 1–4 and 7–10 of each frame. The
optional redundant crosspoint is installed in slots 5 and 6 of each frame.

Each card switches a specific subset of the inputs or outputs. The frames exchange signals on
their expansion cabling.

Figure 3-3 shows the regions of the NV8576-Plus that correspond to the crosspoint cards:

Fig. 3-3: Expanded NV8576-Plus Frames (Front View)

Inputs 1–288 are received by crosspoint cards 1, 2, 7, and 8 in frame 1.

Inputs 289–576 are received by crosspoint cards 3, 4, 9, and 10 in frame 1.

Inputs 577–864 are received by crosspoint cards 1, 2, 7, and 8 in frame 2.

Inputs 865–1152 are received by crosspoint cards 3, 4, 9, and 10 in frame 2.

68

Outputs 1–288 are distributed by crosspoint cards 1 and 3 in frame 1, and 2 and 4 in frame 2.

Outputs 289–576 are distributed by crosspoint cards 7 and 9 in frame 1 and 8 and 10 in frame 2.

Outputs 577–864 are distributed by crosspoint cards 1 and 3 in frame 1, and 2 and 4 in frame 2.

Outputs 865–1152 are distributed by crosspoint cards 7 and 9 in frame 1 and 8 and 10 in
frame 2.

As for the NV8576, the redundant crosspoint module is in stand-by mode under normal opera­tion; it does nothing unless one of the normal crosspoints fails.

If fail-over is automatic and a normal crosspoint card fails, the frame’s control card causes the
redundant card to take over for the failed card. When the redundant card becomes active, it
sends its outputs to the output cards normally supported by the failed crosspoint card.

Installing Crosspoint Cards

NV8144

The NV8144 has one (primary) crosspoint card slot and one redundant crosspoint card slot. The
cards are installed in the two available slots. If you are facing the front of the router, the primary
slot is on the right, the redundant slot is on the left.

Installing Crosspoint Cards in the NV8144

1 Face the front of the router frame. The crosspoint card slots are located between the output

card slots and input card slots, in the middle of the frame. See Figure 1-4 on page 7.

2 Insert the primary crosspoint card in the right slot of the two. The slots have black card

guides. The redundant crosspoint card is optional. For each card, press the ejector levers
inward, making sure each card is fully seated in its slot.

3 Close the door after the cards have been installed. The door must be closed for the router

cooling system to work properly.

NV8140

The NV8140 has 2 (primary) crosspoint card slots and one redundant crosspoint card slot. The
redundant crosspoint card goes in the middle slot.

Installing Crosspoint Cards in the NV8140

1 Face the front of the router frame. The crosspoint card slots are located between the output

card slots and input card slots, in the middle of the frame. See Figure 1-6 on page 9.

2 Insert primary crosspoint cards in the left and right crosspoint slots. The slots have black

card guides. The redundant crosspoint card is optional and goes in the middle slot. For each
card, press the ejector levers inward, making sure each card is fully seated in its slot.

3 Close the door after the cards have been installed. The door must be closed for the router’s

cooling system to work properly.

 The crosspoint card slots for the NV8140 are narrower than the crosspoint slots for the

NV8144. Do not attempt to install the older (and now obsolete) EM0799 or EM0819 cross­point cards in the NV8140. Physical damage will result.

Installing Crosspoint Cards

NV8280, NV8576, or NV8576-Plus

Crosspoint cards in the NV8280 and NV8576 must be installed in pairs: slots 1 and 2, slots 3 and
4, slots 7 and 8, or slots 9 and 10. For example, you could install crosspoint cards in slots 1 and 2,
but not in slots 1 and 3.

For a stand-alone NV8576-Plus, the requirements are different. You need only those crosspoint
cards that support the slots in which I/O cards are installed.

However, if your router is an expanded NV8576-Plus (i.e, two frames), then crosspoint cards
must be paired to support inter-frame communication.

Install Crosspoint Cards in the NV8280, NV8576, or NV8576-Plus

1 Face the front of the router frame.

For the NV8280, the crosspoint card slots are at the bottom of the frame. See Figure 1-8 on
page 11.

For the NV8576 and the two frames of the NV8576-Plus, the crosspoint card slots are located
in the middle of the frame. See Figure 1-10 on page 14.

2 Insert crosspoint cards in slots. The slots have black guides. From the front of the router

frame, the crosspoint card slots are numbered 1 through 10, from left to right.

CAUTION

Do not drop, roughly handle, or stack circuit boards. If you cannot easily
insert or remove a board, stop and contact Grass Valley Technical Support.

Fig. 3-4: NV8280 Crosspoint Card Slots (Front View)

3 Crosspoint cards must be installed in adjacent pairs (In the NV8280 and NV8576). If your

NV8280 or NV8576 is not fully populated with I/O cards, you might not need a full comple­ment of crosspoint cards. Install crosspoint cards in adjacent pairs:

Slots 1 and 2

Slots 3 and 4

Slots 7 and 8

Slots 9 and 10

according to the I/O cards they must switch.

5 For all cards, press the ejector levers inward, making sure each card is fully seated in its slot.

6 Close the frame door after the cards have been installed. The door must be closed for the

router cooling system to work properly.

Redundant Crosspoint Functions

By default, the redundant crosspoint module operates in standby mode. It is intended to
assume the operation of any single crosspoint card that fails. However, an operator can choose,
at any time, to have one of the crosspoint card slots placed in standby mode and have the
redundant crosspoint card take over active control of that card’s inputs and outputs. The oper­ator might, for example, want to swap out a crosspoint card.

Each of the redundant crosspoint modules has one or more buttons at its front. The use of the
buttons varies with the router.

To place the redundant crosspoint module in standby mode

Press ‘Standby’ on the redundant crosspoint module. Any deactivated crosspoint card becomes
active again.

Note that you cannot deactivate another crosspoint card without first pressing the ‘Standby’
button. Buttons for other crosspoint cards turn off when any crosspoint is inactive.

Remote Operation of the Redundant Crosspoint

MRC’s ‘Redundant Crosspoint’ page contains a graphic image of the redundant crosspoint
button panel of a selected router. By clicking on the “buttons” of this image, MRC users can
effect redundant crosspoint switches manually.

(The image in MRC also reflects redundant crosspoint switches made either automatically or by
other operators.)

Operating the redundant crosspoint buttons in MRC is exactly like operating the buttons of the
actual redundant crosspoint module. See the MRC Users Guide for reference.

When a router configuration includes “null” audio sources, control panel operators can control
whether embedded audio channels are null. Individually, null channels carry silence. When all 4
channels in an audio group are null, the output embedder does not emit the group in the
output.

Note that although a null audio source is called a source, it does not actually carry audio. It is an
artificial port. Using that port signals to the router’s control card that generated silence should
be applied at the output.

Crosspoints

Pass-Through Audio

See Embedded Group Control on page 35 for more information.

Pass-Through Audio

When a router configuration includes “pass-through” audio sources, control panel operators can
route the embedded audio from a standard video input to a hybrid (disembedder/embedder)
output directly and with little effort.

Two forms of pass-through audio exist:

• Basic — a single source that governs all 16 audio channels of a video source as a unit.

When a control panel operator specifies the basic audio source, all 16 audio channels of the
disembedder/embedder output are taken from the video routed to that output.

• Extended — defines 16 individual pass-through audio sources, one for each audio output

channel.

When a control panel operator specifies one (or more) of the pass-through audio sources,
the audio source channel specified by the pass-through selection is sent to the selected
audio channel of the output.

For example, if audio source 131 is specified as pass-through channel 3, when a panel opera­tor “takes” audio port 131 to the output, what happens is that audio channel 3 of the video
routed to the output is taken (or “passed through”) to the chosen audio channel of the out­put.

The disembedder on the output cards makes those audio channels available. The multi­plexer on the output card does the individual channel selection.

Note that although pass-through audio sources are called sources, they do not actually carry
audio. They are artificial ports. Using these ports signals to the router’s control card that audio
should be taken from the video at the output.

Nevertheless, the control panel operator treats the pass-through sources as if they were actual
sources, but knowing that the effect of using a pass-through source is to obtain the audio from
the video already present at the output.

Techniques for configuring and using pass-through audio are discussed under Configuring Pass-

Through on page 78.

Pass-Through Audio Sources

“Pass-through” is a concept designed with respect to the disembedder/embedder output cards
of NV8500 family routers.

The concept of pass-through was created to allow panel operators to take audio from standard
input cards to hybrid output without an extraordinary amount of effort. It is the disembedder/
embedder output card that performs pass-through.

Each output of a disembedder/embedder card has logic that allows “pass-through” (as well as
null audio). Figure 3-5 illustrates one such output:

Fig. 3-5: Output of Disembedder-Embedder Card

The output path has a disembedder that extracts the audio from the video source and an
embedder. Each audio channel, i, of the embedder receives one of 3 multiplexed inputs:

• Audio channel i from the disembedder.

• Silence.

• An audio signal from the router’s audio matrix.

Each embedder channel has a ‘null’ flag (i.e., the ‘Insert Silence’ flag) set by the logic of
embedded group control. (See Embedded Group Control

on page 35.) If the channel’s null bit is
set, the EGC logic will drop the entire group if all its null bits are set. Otherwise, the channel
carries generated silence.

If the embedder’s audio channel is not null, the audio comes from the disembedder if the
channel’s pass-through bit is set. Otherwise, the audio comes from the router’s audio matrix.

Basic and Extended Pass-Through

Panel operators are given the choice of basic pass-through and extended pass-through:

• Basic. The operator routes an audio source designated as the basic pass-through source to

an output. The result (given a correct NV9000-SE Utilities configuration) is that all 16 audio
output channels are taken from the video at the output.

• Extended. The operator can route up to 16 audio sources configured as “extended” pass-

through sources to the output. The audio outputs represented by those pass-through
sources are taken from the video at the output.

77

Crosspoints

Pass-Through Audio

The panel operator must be aware of the names (configured in NV9000-SE Utilities) of the basic
pass-through source and the individual “extended” pass-through sources.

Configuring Pass-Through

Pass-through configuration is performed in MRC and in NV9000-SE Utilities. Pass-through
sources can then be used as often as required by panel operators.

To configure pass-through in MRC, go to the ‘Router Levels’ page. Specify (1) a basic pass­through source in the ‘Pass-Thru Audio Source’ field and (2) up to 16 extended pass-through
sources in the ‘Pass-Thru Shuffle Audio Sources’ table. These sources will be sacrificed: you
cannot use the pass-through source as a normal audio source. Therefore, choose unused audio
port numbers for pass-through sources.

 Regarding unused audio port numbers: always choose unused audio port numbers that are

greater than the number of video input ports of the router. Unused port number between
1152 and 2304 will work well for any NV8500 router.

Basic Pass-Through Source

In NV9000-SE Utilities, create an audio source device whose port number is the same as the
basic port number you entered in MRC’s router levels page. This source should not have a video
level. Name the source “passthru” or something similar that is acceptable to panel operators.

After the router and the NV9000 control system are configured and running, control panel oper­ators may use the designated pass-through source to perform pass-through routes.

Panel operators make a basic pass-through route by taking the pass-through audio source to
the desired destination.

When the router detects that the pass-through source was selected, it does not route audio
from the pass-through source, but sets the pass-through flags for all 16 audio channels. These
flags tell the output to use the corresponding disembedder channel output in the output
stream. Refer to Figure 3-5.

78

Extended Pass-Through Sources

There are several ways to configure pass-through audio sources in NV9000-SE Utilities. The
different methods are used in different ways and have different purposes.

Method 1

Create a (single) source device whose individual audio port numbers are the same as the
numbers you entered in the ‘Pass-Thru Shuffle Audio Sources’ table of MRC’s router levels page.

This source should have as many audio levels as your video signals carry. It does not matter
whether the source has a video level. Name the source something that is acceptable to panel
operators as a pass-through source.

After the router and the NV9000 control system are configured and running, control panel oper­ators may use the designated pass-through source to perform pass-through routes.

audio channels of the video at the output straight through to the output without shuffle.

A shuffle could be accomplished if the panel operator is willing to perform a level mapping.

The second method, discussed next, addresses shuffling.

Method 2

Create multiple source devices whose individual port numbers are the same as the numbers you
entered in the ‘Pass-Thru Shuffle Audio Sources’ table of MRC’s router levels page.

You should create a source device for each of the pass-through audio sources in the table. Each
source device has just one level that matches a pass-through source you defined in MRC. Name
these sources in a way that is acceptable to panel operators. We recommend you create a cate­gory for these sources. A panel operator will then be able to select any pass-through channel
with just 2 button presses.

After the router and the NV9000 control system are configured and running, control panel oper­ators may use the designated pass-through sources to perform pass-through routes with
shuffle.

Panel operators make an extended pass-through route by creating a breakaway of the individual
pass-through audio channels from the defined pass-through source to the desired destination.

Thus, if the MRC pass-through list is . . .

1 1281 5 1285 9 1289 13 1293
2 1282 6 1286 10 1290 14 1294
3 1283 7 1287 11 1291 15 1295
4 1284 8 1288 12 1292 16 1296

. . . then your 16 sources, defined in NV9000-SE Utilities, would have levels

Source Name Level Port
Pass1 Audio 1 1281
Pass2 Audio 2 1282
. . .
Pass16 Audio 16 1296

and the category could perhaps be named PASSTHRU.

Switching Rules

The general procedure for performing pass-through takes (with shuffle) is:

1 Selects a destination.

2 Select a destination level (say Audio 3).

3 Choose a pass-through source (say Pass12).

(Taking pass12 to audio 3 of the destination means that audio channel 12 of the video at the
input is taken to audio channel 3 of the output.)

4 Repeat steps 2 and 3 for any other portions of the overall audio shuffle you want to achieve.

5 Press ‘Take’.

This method gives operators independent control of all pass-through channels (or as many
pass-through channels as you want your system to have).

Notes

When the router detects that the pass-through source was selected, it does not route audio
from the pass-through source, but sets the pass-through flags for the chosen audio levels. Each
flag tells the output to use the corresponding disembedder channel output in the output
stream. Refer to Figure 3-5.

 A port designated as the “pass-through source” cannot also be used as a normal source.

 “Pass-through” audio is not compatible with DHP.

 If a pass-through source is “taken” to an output that is not on a disembedder/embedder

card, the take is rejected (with an error message).

 Only NV8500 family routers (at firmware version 3.3.1 or later) support pass-through audio.

Switching Rules

There are presently 4 aspects involved in what are called “switching rules.”

• Embedded group control (and “null” audio).

• Pass-through audio.

• Obsolete ‘AFV’ partition.

• Input attribute — force embedder on.

• Tal ly — effective status versus actual status.

AFV Partition

The routers’ switching rules accommodate ‘AFV’ partitions, but AFV partitions are not supported
by recent releases of MRC.

 If your router has an AFV partition and you want to continue to use it, do not delete it. You

cannot recreate it in the newer versions of MRC.

Force Embedder On

MRC allows you to specify a “force embedder on” attribute for any and all inputs. When the
attribute is off, the output embedder obeys general switching rules. When the attribute is on,
the embedder is forced on, regardless of other factors.

NV8500 Series

User’s Guide

 Embedders on disembedder/embedder output cards are always on.

Tally

There are two forms of tally: “effective” status and actual status.

“Effective status” applies to standard input cards. Audio sources from standard input cards are
tallied as if they were from a disembedding input card.

“Actual status” applies to disembedder cards or MADI input cards. Here, audio tally consists of
actual audio sources.

Understanding How the Rules Combine

The rules are complex and mutually contradictory. The easiest way to understand how the rules
work is to follow the algorithm that implements the rules. The algorithm to determine whether
to bypass the embedder is portrayed in simple terms here.

IF video matrix take

Set video source
IF level is AFV // ’AFV level’ is an obsolete feature

Flag = TRUE // Flag referenced at end of procedure

ELSE -- not AFV level

IF input is ‘force embedder on’

Flag = FALSE

ELSE

IF standard or MADI input to EMB output

Flag = TRUE

ELSE

Flag = FALSE

ENDIF

ENDIF -- force embedder

ENDIF -- AFV level

ELSE -- audio matrix take

IF null audio source // do "embedder group control"

IF MADI destination

Return "Invalid Destination" // no nulls to MADI output

ELSE

Set audio source
Set ’Insert Silence’ flag
Flag = TRUE

ENDIF

ELSE -- regular audio source

IF standard input

Return "Invalid Source" // can’t route audio from std source

ELSE

IF standard or "!EM" output // !EM a special output card

Return "Invalid Destination" // can’t route audio to such dests

ELSE

Set audio source
Clear ’Insert Silence’ flag
IF DIS or MADI input to EMB or MADI output

Flag = FALSE

ELSE

Flag = TRUE

ENDIF

ENDIF -- valid dest

ENDIF -- valid source

ENDIF -- null or not

ENDIF video or audio

IF Flag

bypass embedder and tally effective status

Switching Rules

ELSE

ENDIF

Notes:

1 The objective of this logic is to determine whether to bypass the embedder and whether to

set the ‘Insert Silence’ flag. The ‘Insert Silence’ flag governs whether the null audio source is
used.

(The ‘Insert Silence’ flag — or ‘null’ flag — is part of the pass-through logic of disembedder/
embedder outputs.

2 The “force embedder” attribute is specified in MRC’s ‘Input Attributes’ page.

Router Control

The routers’ control cards receive commands from an external router control system (typically,
the NV9000) and in turn send commands to the input, output, crosspoint, and monitor cards for
execution. The control card also sends the status of the router, its power supply, fans, and video
reference to the router control system.

There are two control cards available: the EM0666 card for router frames with only standard I/O
cards installed and the EM0833 card for frames with at least one hybrid I/O cards installed. The
installation of any hybrid I/O card requires that all crosspoint cards and all control cards also be
hybrid.

Each router frame has two control card slots: one is for an active control card and the other is for
a stand-by control card. Both control cards must be either standard or hybrid.

For a list of control cards available and part numbers, see Control Cards

Overview of Control Cards

Every router has a primary control card. An optional secondary control card can be installed as a
redundant, standby card. Both control cards receive commands from the router control system,
but only the active control card responds. Because both cards receive commands, if the active
control card fails, the standby control card automatically takes over without interruption. In
addition, the primary control card and secondary control card communicate with each other so
that should a card fail, the remaining card communicates the failure to the router control
system.

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 (yellow), and operating normally (green). For more information, see Indicator LEDs
on page 193.

Installing Control Cards

The card slots that house control cards are associated with specific router control system
connections. If you are installing only a primary control card, you must install the card in the slot
associated with the primary router control system connection. If you are installing both a
primary and secondary control card, both card slots are used and there is no need to distinguish.

CAUTION

Do not drop, roughly handle, or stack circuit boards. If you cannot easily
insert or remove a board, stop and contact Grass Valley Technical Support.

There are no backplanes associated with control cards. All communication is through the router
control system connections.

Installing Control Cards

1 Face the front of the router frame. The control card slots are located at the far right of the

frame, next to the input cards, and have yellow card guides.

For the NV8144, see Figure 4-1.

For the NV8140, see Figure 4-2, next page.

For the NV8280, see Figure 4-3, next page.

For the NV8576 or NV8576-Plus, see Figure 4-4 on page 86. The control cards are installed
only in the upper region of the frame. No control cards are installed in the lower region of
the frame.
