DM-NVX Series:
DigitalMedia™ 4K60 4:4:4 HDR
Network AV Encoders/Decoders
Introduction
The Crestron® DM-NVX series transports ultra high-definition 4K video with 60 Hz frame
rates and 4:4:4 color sampling over standard Gigabit Ethernet. Support for high dynamic
range video (HDR10) and HDCP 2.2 ensures high picture quality and compatibility with a
variety of media sources. The DM-NVX series uses JPEG 2000 compression and encoding,
achieving a low end-to-end latency of 30 ms at 60 fps. The DM-NVX series accepts SFP
(Small Form-factor Pluggable) transceiver modules (Crestron SFP-1G series), which support
multimode and single-mode fiber.
The DM-NVX series consists of the DM-NVX-350 and DM-NVX-351 stand-alone endpoints
and the DM-NVX-350C and DM-NVX-351C cards. The cards are designed to occupy the
DMF-CI-8 card chassis. The DM-NVX-351 and DM-NVX-351C provide the same
functionality as the DM-NVX-350 and DM-NVX-350C with the addition of surround sound to
stereo downmixing.
This manual provides information about the following:
• Physical description of the connectors, controls, and indicators on the DM-NVX
series
• Configuration of some of the capabilities of the DM-NVX series, for example,
encoding and decoding functionality
• HDCP 2.2 compliance
• IGMP snooping
• Troubleshooting guidelines
In addition, information about device discovery of a DM-NVX device using Crestron
Toolbox™ software is provided in the appendix of this manual. For installation information,
refer to the DM-NVX-350/DM-NVX-351 DO Guide (Doc. 7799) and the DM-NVX-350C/
DM-NVX-351C DO Guide (Doc. 7975). For information about designing a network for a
DM-NVX system, refer to the DigitalMedia™ NVX Series Design Guide (Doc. 7977).

Configuration
The DM-NVX series can be configured using the web interface, which can be accessed
from a web browser by entering the IP address or hostname of the device. SIMPL Windows
can also be used to configure the DM-NVX series.
This section provides information about configuration of the following items using the web
interface or SIMPL Windows:
• Encoding and decoding functionality
• Stream statistics
• Automatic routing of video inputs
• Video wall processing
• Adjustable underscan
• User-selectable output resolution
• Maximum color depth and color space mode
• EDID
• Subscriptions
• Daisy chain
• 7.1 Surround sound audio
• Analog audio input or output
• Breakaway audio
• USB 2.0 routing
Encoding and Decoding Functionality
A DM-NVX device can be configured to function as a network AV encoder (transmitter) or
decoder (receiver):
• As an encoder, a DM-NVX device allows a laptop computer, camera, or other
media source to be connected via an HDMI cable and then transmitted over the
network.
• As a decoder, a DM-NVX device receives the signal from a DM-NVX encoder and
feeds the signal to a display device via the HDMI output. A DM-NVX decoder can
switch among multiple DM-NVX encoders on the network alongside locally
connected HDMI sources.
To configure a DM-NVX device as an encoder or decoder, use the web interface or SIMPL
Windows as discussed in the following sections.
6 • DM-NVX Series: 4K60 4:4:4 HDR Network AV Encoders/Decoders Product Manual – DOC. 7839D
Configuration Using the Web Interface
Configure a DM-NVX device as an encoder or decoder on the Stream page of the web
interface. In the
Receiver (decoder).
Stream Page - Encoder (Transmitter) or Decoder (Receiver) Configuration
When a different mode is selected, a prompt appears asking for confirmation that the device
be rebooted. Click
Mode drop-down list, select Receiver or Transmitter. The default setting is
Yes to reboot the device.
Device Reboot Prompt
For additional information, refer to the online help of the web interface.
Configuration Using SIMPL Windows
Using top-level programming for the DM-NVX device, set the <DeviceMode> analog input
join to the desired mode (
Changing modes requires that the device be rebooted. Trigger the <Reboot> digital
input join to reboot the device. For additional information, refer to the SIMPL Windows
help file.
Receiver or Transmitter). The default setting is Receiver.
Stream Statistics
Statistics can be displayed to indicate the number of packets received or transmitted, the
number of dropped packets, and the bit rate of the received or transmitted stream.
To enable or disable stream statistics, use the web interface or SIMPL Windows as
discussed in the following sections.
