Design Guide – DOC. 7977F DM NVX System •1
Introduction
A Crestron® DM NVX™ system is a digital video and audio distribution system that
switches 4K video sources and displays at 60 frames per second (fps) with full 4:4:4 color
sampling and High Dynamic Range (HDR) video support. Using standard 1-Gigabit
Ethernet infrastructure, a DM NVX system provides a highly flexible, cost-effective,
and infinitely scalable network AV solution.
Pixel Perfect Processing technology is incorporated into a DM NVX system to provide
flawless video transport in all applications. A video signal is encoded and decoded to
achieve imperceptible end-to-end latency of less than 1 frame. The image quality of the
source is maintained across a 1-Gigabit network at any resolution up to 4K60 4:4:4.
A variety of DM NVX endpoints are available offering flexibility in endpoint selection.
In addition to surface-mountable and card-based form factors, the endpoints are
available as encoder-only, decoder-only, and combined encoder/decoder products.
A DM NVX Director™ virtual switching appliance can be added to configure, control, and
manage a DM NVX system.
This guide aids in the design and installation of a DM NVX system. The guide provides
information about the following:
•System design, which includes endpoint and network design
•System installation, which includes endpoint and network installation
•Case studies
In addition, a glossary is provided at the end of the guide.

System Design
The following sections provide design information related to DM NVX endpoints and the
network.
Endpoint Design
A DM NVX system is composed of one or more encoder endpoints and one or more
decoder endpoints. Additional components of a DM NVX system include the DM NVX
Director virtual switching appliances and SFP (Single Form-factor Pluggable)
transceiver modules.
The following sections provide information about DM NVX endpoints, DM NVX Director
virtual switching appliances, SFP modules, and related system design considerations.
DM NVX Endpoints
DM NVX endpoints are available in two form factors:
1. Surface-mountable endpoints, which provide a compact design that allows an
easy fit in various types of locations, for example, behind a flat panel display
2. Chassis-based cards, which are used with the DMF-CI-8 card chassis for
sources in close proximity to a rack or for applications requiring a high density
of endpoints
Surface-Mountable Endpoints
Surface-mountable endpoints consist of the following models:
•DM-NVX-35x Series encoders/decoders (DM-NVX-350, DM-NVX-351,
and DM-NVX-352)
•DM-NVX-E30 encoder
•DM-NVX-D30 decoder

DM NVX Director Virtual Switching Appliances
A DM NVX Director virtual switching appliance emulates the functionality of the
traditional hardware-based matrix switcher (for example, the DM-MD8X8-CPU3).
The virtual switching appliance allows comprehensive system configuration,
management, and signal routing of a DM NVX system.
The DM NVX Director web interface allows automatic discovery of each DM NVX
endpoint on the network and the assignment of each endpoint to a domain. The web
interface also enables custom endpoint naming and search tools, an XML-based device
map file for import and export, logging, diagnostics, and SNMP messaging support.
DM NVX Director models consist of the DM-NVX-DIR-80, DM-NVX-DIR-160, and
DM-NVX-DIR-ENT. The following sections provide information about each model.
DM-NVX-DIR-80
The DM-NVX-DIR-80 includes four 1-Gigabit Ethernet RJ-45 interfaces and a dedicated
Intelligent Platform Management Interface (IPMI). Best suited for single large rooms,
the DM-NVX-DIR-80 supports 80 devices and a single domain.

SFP-1G and SFP-10G Transceiver Modules
Crestron SFP-1G and SFP-10G transceiver modules provide fiber connectivity, which
offers greater transmission distances than traditional copper. SFP-1G modules can be
used with the DM NVX endpoints and DM-NVX-DIR-ENT. SFP-10G modules can be
used with the DM-NVX-DIR-ENT only. The following sections provide information about
the modules.
SFP-1G Modules
Available SFP-1G modules consist of the following:
•SFP-1G-SX: 850 nm multimode fiber connections up to 550 m (1800 ft) over
LC-terminated OM3 or OM4 fiber
•SFP-1G-LX: 1310 nm single-mode fiber connections up to 10 km (6.2 mi) using
LC-terminated G.652 fiber
•SFP-1G-BX-U: 1310 nm/1490 nm single-mode fiber uplink connections up to

•SFP-10G-BX-D: 1330 nm/1270 nm single-mode fiber connections up to 10 km
(6.2 mi) using LC-terminated G.652 fiber
For the DM-NVX-DIR-ENT, the connectivity options and the distance requirements
determine the appropriate module that is to be used.
Endpoint Bandwidth Design and Management
A single DM NVX network link can carry the following data streams:
•Primary Audio/Video Stream: HDMI® or analog audio and HDMI video that are
encoded and sent to the network for decoding by a remote endpoint
•Secondary Audio Stream: Audio stream that is encoded and sent for decoding
independently of the primary audio/video stream
•USB Device and Host Traffic: USB data from the DM NVX device or host port
(available on DM-NVX-35x and DM-NVX-35xC devices only)
•Other Ethernet Traffic: Control data as well as data from DM NVX network
ports connected to third-party devices such as displays or cameras. Ethernet
traffic also includes network protocol traffic such as DHCP, DNS, and RADIUS
for 802.1X.
Default video bit rate settings are sufficient for most installations but can be adjusted
to accommodate unique situations. Ethernet bandwidth ratings are bidirectional;
therefore, full USB 2.0 bandwidth is supported for DM-NVX-35x and DM-NVX-35xC
devices. In an installation in which video from a PC is encoded and sent to a decoder at a
display, and a high-bandwidth USB camera at the display sends USB video back to the
PC, no bandwidth issues exist. Although the sum of all traffic may exceed 1 Gbps in this
scenario, the traffic in each direction is less than 1 Gbps.

14 •DM NVX System Design Guide – DOC. 7977F
Example of Bidirectional Bandwidth under 1 Gbps
An encoder that attempts to send 900 Mbps video and 480 Mbps USB 2.0 traffic
exceeds the maximum network link bandwidth of 1 Gbps and, as a result, the link will fail.
Example of Failed Link with Required Bandwidth Greater than 1 Gbps
DM-NVX-35x and DM-NVX-35xC devices support Layer 2 and Layer 3 transport of
USB 2.0 data. For Layer 2 transport, one local connection to the device port of a
DM NVX device supports up to seven remote host port connections simultaneously.
When multiple remote connections are required, a hub must be used to connect to each
remote host port. To prevent excessive USB traffic for Layer 2 support of multiple
remote connections, only one high-bandwidth USB device can be used regardless of the
number of remote connections.
For USB 2.0 Layer 3 transport, one local connection supports only one remote
connection. Layer 3 supports USB 2.0 transport of data across VLANs.

Endpoint Design Considerations
To implement an optimal configuration for a DM NVX system, consider the following
factors for each endpoint:
•If rack-mount sources are required or if a high density of endpoints must exist
in close proximity to each other, use card-based endpoints.
•If simultaneous stereo downmixing alongside multichannel audio output is
required, use the DM-NVX-351 or DM-NVX-351C.
•If Dante® or AES67 audio networking is required, use the DM-NVX-352 or
DM-NVX-352C.
•For an encoder-only endpoint and when video switching is not required, use the
DM-NVX-E30 or DM-NVX-E30C.
•For a decoder-only endpoint and when scaling is not required, use the
DM-NVX-D30 or DM-NVX-D30C.
•Follow the guidelines for cable types as specified in TIA/EIA-568 for choosing and
certifying cables in a DM NVX installation.
•Refer to the following table for guidelines on some of the primary network
connectivity options that can be used at the endpoint.

SFP-1G-BX-U G.652 SMF 10 km (6.2 mi)
SFP-1G-BX-D G.652 SMF 10 km (6.2 mi)
•The DM NVX surface-mountable endpoints provide IR and serial ports to control
in-room devices. Use a Crestron control processor such as a PRO3 or AV3 in a
design that uses IR and serial ports or in a design that requires relay I/O or
Cresnet® device control.
•Although both a USB 2.0 host port and a USB 2.0 device port are available on
DM-NVX-35x and DM-NVX-35xC endpoints, both ports cannot be used
simultaneously.
•High-bandwidth USB devices such as cameras and storage can have an impact
on overall video bandwidth. For additional information about how to manage
high-bandwidth USB devices and the direction of bandwidth consumption, refer
to “Endpoint Bandwidth Design and Management” on page 13.
•If additional HDMI inputs are required for local switching at the endpoint within
typical HDMI cable distances of 15 ft (5 m), consider using other Crestron
solutions—such as the Crestron DM MD and DMPS families of products—in
conjunction with the endpoint.

16 •DM NVX System Design Guide – DOC. 7977F
•In many DM NVX installations, configure specific control surfaces (such as
Crestron touch screens) and additional switch options (such as local HDMI
switches) at endpoints.
Network Design
DM NVX systems require a designed and provisioned Ethernet network to function
correctly. Be sure to gather requirements and documentation, coordinate with IT staff,
and complete network design prior to site work.
Minimum Network Requirements
Minimum network requirements must be met for a successful installation. Minimum
requirements consist of the following:
•Network switch:
-1-Gigabit port for every connected DM NVX endpoint
-Nonblocking backplane
-Layer 3
-IGMPv2 implementation
•Network switch settings:
-IGMPv2 snooping enabled
-IGMPv2 querier enabled
-Fast-leave enabled (also known as immediate-leave)
•Inter-switch uplinks (if required):
-The uplinks must have sufficient bandwidth for all encoders and decoders
connected to the network switch. Allocate 1 Gigabit per encoder or decoder
connected to the switch.
-Uplinks must be configured properly to support multicast traffic.
Network Design Overview
DM NVX networks must be designed to isolate traffic on network segments specifically
architected for DM NVX devices. This can be accomplished by using separate
infrastructure, Virtual Local Area Networks (VLANs), or Multi-Protocol Label Switching
(MPLS). DM NVX network segments carry DM NVX multicast streams, DM NVX control,
and ancillary traffic.
The location of other Crestron network devices relative to network infrastructure
must be determined. A decision must be made as to whether the devices are to coexist
on the same network segment as the DM NVX segment or on another segment that
has traversal capabilities to the DM NVX segment but is not multicast enabled.
Networked AV devices other than DM NVX devices can be placed on the DM NVX
network segment if their bandwidth requirements are relative to the DM NVX endpoint
bandwidth requirements.
