Product Summary
The NV5128 Multi-Format Router is a highly flexible router supporting audio and video signals,
both analog and digital, in a variety of combinations. (See Signals Types and Rates on page 5.) The
router can support up to 128 inputs and 128 outputs (256 inputs and 256 outputs mono), typically
organized in a block of 16 inputs and 16 outputs, expandable in increments of 16. A fully non-
blocking matrix architecture, allows for one-to-one and one-to-many routing.
For audio signals, the NV5128 routes stereo signals internally as mono channels, enabling the
recombination of channels to create new stereo signals. Analog audio signals are routed internally
as digital signals. Converters housed on I/O cards convert incoming analog signals to digital and
outgoing digital signals to analog as needed.
For video signals, the router can manage Standard Definition (SD) separately, or SD and High Def-
inition (HD) signals combined, referred to as Super Wide Band (SWB). Analog video signals are
routed internally without being converted to digital. However, an Analog Video Converter (AVC)
card is available for the conversion of analog to digital and digital to analog.
Additionally, longitudinal time code signals and machine control signals can also be routed within
the same frame enabling you to meet unique switching needs.
Active input cards, output cards, and control cards are “hot swappable” and installed through the
front of the frame for easy access. The rear of the router features a back plate into which backplanes
housing different types of connectors for receiving and distributing signals are installed. Each back-
plane receives or distributes signals for a single active card allowing for maximum switching con-
figuration flexibility: backplanes are not pre-installed in pre-selected router slots. The back plate
also contains connections to system functions, such as a router control system, alarms or reference
signals.

2. Introduction
Power Supply
Mounting
The NV5128 is designed to mount in a standard EIA rack with minimum dimensions of 8RUs
(13.97 inches, 354.8 mm) high, 19 inches (482.6 mm) wide, and approximately 18 inches (457 mm)
deep. Because of the router’s compact size, multiple routers can be mounted in a single rack, saving
facility space. For installation instructions, see Rack Mount on page 37.
Fuses
Active cards feature a “fast blow” or resettable fuse. If the card requires a large amount of power,
the fuse is “fast blow” and must be replaced if blown. If the fuses are resettable, the fuses either
reset automatically or can be reset manually by removing the card from the frame. For more infor-
mation on fuses, see Fuse Replacement on page 76.
Cooling
The NV5128 frame has a single fan tray containing three fans with variable fan speed control. The
fans draw cooling air from the front of the router, through the door, and exhaust it through the rear
of the frame. The router must have the door installed and closed for proper airflow through the
chassis.
Each fan features speed control which spins the fan at the optimal rate required to ensure that a con-
stant temperature is maintained within the router. Temperature sensors on the fans sense the exiting
temperature and speed up or slow down the spinning of the fan as required. By spinning only as
needed to meet cooling needs, fan noise is significantly reduced in partially loaded frames or in
environments with lower ambient temperatures. In addition, by maintaining a constant temperature,
circuitry life span is increased.
Each fan features two LEDs that indicate if the fan is receiving power and if there is a failure. For
more information, see Indicator LEDs on page 76.
Filters
There is a removable air filter located on the inside of the door assembly. It is recommended that
maintenance of the fan tray and filters be performed on a regular basis. For more information, see
Air Flow on page 78.
Power Supply
The NV5128 uses the NVISION PS6000 power supply module, housing one primary module and
one optional module (for redundancy). The PS6000 power supply module accepts a wide range of
AC input voltages and produces five +48 VDC outputs. The power supply automatically senses the
AC input voltage (90–130 and 180–250 VAC) and adjusts to maintain a relatively constant DC out-
put; no voltage selection is required.
The five regulated outputs are directed to modules in the router where on-board regulators produce
the DC voltages required by the local circuits. Each +48VDC output powers one of the five green

LEDs and output test points located on the front of each PS6000 power supply module. Under nor-
mal operation, all five LEDs are lit. For more information, see Indicator LEDs on page 76.
Figure 2-1 shows the power supply architecture.
Figure 2-1. PS6000 Power Supply Module Diagram
Fuses
A fuse for the AC power inputs is located on the PS6000 power supply modules. When a NV5128
is ordered, fuses appropriate for the line voltage in use at the country of destination are installed on
the PS6000 power supply modules. Be sure to check the fuse ratings for compliance with specific
requirements in your area. An 8A fuse (part number HB0145-00) is required for 90–130 VA C a p p l i -
cations. For 180–250 VAC operation, a 6.3A fuse (part number HB0031-00) is required.
The fuses are “slow blow” and designed to blow if there is an ongoing power issue, but not if there
is a single, minor spike in the power flow. For information on replacing fuses, see Fuse Replace-
ment on page 76.
Cooling
There are four low-speed fans located along the front edge of each PS6000 power supply module.
Each fan pulls a small quantity of air across internal heat sinks.
Signals Types and Rates
The NV5128 supports several signals within a single router. Supported audio signals are analog,
AES synchronous and AES asynchronous. Supported video signals are analog, SD, and SWB (SD
and HD combined). Also supported are SMPTE longitudinal time code and machine control sig-
nals.
Incoming audio analog signals are converted to digital with a sample rate of 48kHz for internal
routing and can be distributed externally as digital audio outputs. Conversely, incoming digital
audio signals can be converted and distributed externally as analog audio outputs. In addition, all
stereo signals are separated into left and right channels for switching as mono signals. Mono chan-
nels can be recombined to create new stereo signals. This unique architecture allows for cross-con-
version between analog and synchronous AES signals within the same frame.
Analog and digital video signals can be intermixed with any other supported video format (analog,
SD or SWB) while maintaining a high level of analog video performance, effectively replacing
many single format routers already in use.

Using Video and Audio References
References are required for proper switching. The following lists input signal formats and if a video
or AES reference is required.
Mixing Analog and Digital
The NV5128 frame can mix analog and digital signals within a single routing system. For example,
a digital audio input can be routed to an analog audio output. To perform this action the router uses
analog-to-digital (A/D) converters and digital-to-analog (D/A) convertors.
There are two types of A/D and D/A converter cards: one set for audio and one set for video. Ana-
log audio converter cards cannot be mixed with analog video converter cards. The input signals
type —audio or video —must match the output signal type. For more information on converter
cards, see Active Cards on page 21.

2. Introduction
Switching Configurations
Mono Channels
AES signals are composed of several parts, including a preamble, left channel, right channel, user
bits, and channel status bits. When received as an AES signal, the signal is retained as an AES sig-
nal for internal routing to the output card. The crosspoint array on the output card breaks apart the
signal, separating out the left and right channels to create two mono channels. The mono channels
are then switched as separate signals, recombining left and right channels into new stereo signals.
The channel status bit and user bits are passed through. When the signal is distributed as an AES
output, the preamble, channel status bit and user bits are added back to the left and right channels to
create a stereo signal.
Individual left or right channels can be combined with other individual channels and distributed as
a new channel-pair combination (stereo signal). For example, a live news report may capture the
news reporter’s voice on the left channel and the background noises on the right channel. By split-
ting the AES signal into its left channel and right channel, the news reporter’s voice (left channel)
can be paired with a different background noise (right channel). If only one channel is present, the
other channel is silent.
To perform mono switching, an external AES reference signal must be connected to maintain syn-
chronization (see Making Reference Connections on page 57). How mono signals are recombined
and routed to outputs is determined by the router control system. For more information on mono
signal switching, see Setting Jumpers and Switches on Cards and Card Sets on page 67.
Switching Configurations
Switching is performed by the output card. Each output card receives signals from the input card
via the motherboard and routing commands from the control card. The inputs are then sent to a
crosspoint array on the output card that performs the switching.
Figure 2-2 shows the basic architecture of the NV5128 switching configuration and the relationship
between the backplanes and the input cards and output cards. Backplanes house connections that
receive and distribute signals to and from the router. For more information, see Backplanes on
page 13.
Each “X” (crosspoint symbol) represents a 16 input x 16 output crosspoint array. Taken together,
eight crosspoints create a 128 input x 16 output crosspoint array. This unique architecture creates a
fully non-blocking matrix such that an input can be switched to any output, and one input to one
output, or one input to many outputs.

2. Introduction
Switching Configurations
Figure 2-2. NV5128 Crosspoint Architecture
In general, input cards and output cards follow the 16 inputs x 16 outputs architecture, with one
router card slot per card. There are three exceptions: Classic SWB card sets, Standard SWB cards
and machine control card sets. Each card set switching configuration is discussed in the proceeding
sections.
Classic SWB Switching Configurations
The Classic SWB card set is composed of two cards connected together that occupy two card slots.
The card set has a 16 input x 16 output crosspoint array. A single Classic SWB card set can be used
to create a 16 input x 16 output switching matrix, or a pair of card sets can be coupled together to
create a 32 input x 32 output matrix. The 32 input x 32 output configuration feeds the 16 inputs
from one Classic SWB card set to the second Classic SWB card set and vice versa.
When creating a 32 input x 32 output matrix, the Classic SWB cards must be installed in specific
router slots. For installation instructions, see Installing Classic SWB Backplanes on page 41. For
more information about the card architecture, see Classic SWB on page 28.
Standard SWB Switching Configurations
There are two types of Standard SWB output cards: a main card with a “wing” and optional expan-
sion cards that mate with the wing on the main card. The output cards occupy four contiguous slots.
By installing the main card and up to three expansion cards, different crosspoint matrices can be
created. Because the main output card receives all 128 SWB inputs, switching configurations can
start at 16 inputs x 16 outputs, increasing in increments of 16 up to 128 inputs by 64 outputs. A sec-

ond set of Standard SWB main output cards and expansion output cards can be installed, increasing
the switching configuration to 128 inputs x 128 outputs.
The Standard SWB cards must be installed in specific router slots. For installation instructions, see
Installing Other Video, Audio and Time-Code Backplanes on page 43. For more information about
card architecture, see Standard SWB on page 29.
Machine Control Switching Configurations
The machine control card set is composed of two cards connected together that occupy two card
slots. The machine control card set is bidirectional; it carries signals in both directions (input and
output).
A single machine control card set can support 32 ports. If a second machine control card set is
installed and combined with the first card set, the configuration can be doubled to 64 ports.
The Machine Control cards must be installed in specific router slots. For installation instructions,
see Installing Machine Control Backplanes on page 42. For more information about the card archi-

The NV5128 has slots for input cards, output cards, and control cards. Cards are installed through
the front of the frame for easy access and are “hot swappable”. The rear of the router is a back plate
into which backplanes housing connectors for receiving and distributing signals are installed. The
back plate also contains connections to system functions, such as a router control system, alarms or
reference signals.
Active circuitry is contained mainly on the input cards, output cards, control cards, power supply
modules, and fan tray installed through the router’s front. However, some active circuitry for SD
and HD signals are located on the associated backplanes, which are installed through the router’s
rear. All cards and backplanes are “hot-swappable.”
An internal motherboard spans the frame and interconnects front and rear modules, and distributes
control signals, timing information, and power. Cards, power supply modules, and the fan tray plug
into the motherboard from the front of the router and backplanes plug into the same motherboard
from the rear. Each input card and output card has a corresponding backplane. For more informa-
tion on each type of card, see Active Cards on page 21. For more information on backplanes, see
Backplanes on page 13.
Front Slots
Figure 2-3, next page, shows the front of the NV5128 with the door removed. In the center of the
router are eight slots designated for input cards. To the right and left of the input slots are four slots
designated for output cards. On the far right, two slots house the primary and secondary control
cards. A fan tray is located at the top of the router chassis.
Viewing the frame from the front, slots are numbered 1 through 16, from left to right. (See
Figure 2-3.)
