Product Manual – DOC. 8425D DM-NVX-E30(C)/DM-NVX-D30(C)/DM-NVX-D80-IOAV •1
Introduction
Crestron® DM NVX® network AV encoders/decoders transport 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 (HDR) video and HDCP 2.2 ensures high picture quality
and compatibility with a variety of media sources. Using Pixel Perfect Processing
technology, a video signal is encoded and decoded to achieve imperceptible end-to-end
latency of less than 1 frame.
DM-NVX-E30(C) devices consist of the DM-NVX-E30 surface-mountable endpoint
and the DM-NVX-E30C card, which function as encoders (transmitters) only.
DM-NVX-D30(C) devices consist of the DM-NVX-D30 surface-mountable endpoint and
the DM-NVX-D30C card, which function as decoders (receivers) only. The DM-NVX-D80-
IOAV also functions as a decoder only and is compatible with the Intel® OPS (Open
Pluggable Specification).
Compact in design, the DM-NVX-E30 and DM-NVX-D30 are designed to mount to a flat
surface such as a wall. The DM-NVX-E30C and DM-NVX-D30C are designed to occupy
the DMF-CI-8 card chassis. The DM-NVX-D80-IOAV is designed for installation into the
OPS slot of an OPS-supported display.
NOTE: The DM-NVX-D30, DM-NVX-D30C, and DM-NVX-D80-IOAV do not support
video scaling.
This manual provides information about the following:
•Physical description
•Status and configuration
•IGMP snooping

two conditions exist:
1. No video stream is present.
2. The internal temperature of the device does not exceed the normal
operating range.
•Always On: The fan runs continuously regardless of video stream status and
internal temperature of the device.
Fan status is indicated as either of the following:
•Full On: The fan is running.
•Off: The fan is not running.

Using SIMPL Windows
Using the top-level programming slot for the DM-NVX-D30, set the <FanControl>
analog input join to the desired setting. The <FanControl_F> analog output join reports
the fan mode of operation. The <FanStatus_F> analog output join reports the fan
status. For additional information, refer to the SIMPL Windows help file.
Automatic Point-to-Point Connectivity
Point-to-point connectivity enables a DM NVX encoder to be connected directly to a
DM NVX decoder to stream video, audio, and, if applicable, USB signals. Rather than
being connected to an Ethernet switch, a 1000BASE-T Ethernet port of an encoder is
connected directly to a 1000BASE-T port of a decoder. By default, point-to-point mode
is enabled (set to Auto) and can be disabled if desired. When enabled, no additional
configuration is required for the encoder or decoder to operate in point-to-point mode.
To enable or disable point-to-point mode, use the web interface or SIMPL Windows as
discussed in the following sections.
Using the Web Interface
Enable or disable point-to-point mode by clicking the Settings tab and then clicking
System Setup.
In the Point-to-Point Control section, Point to Point Status indicates whether point-to-
point mode is Active or Inactive.
In the Point-to-Point Mode drop-down list, select either of the following:
•Auto: (Default setting) A 1000BASE-T port of a DM NVX encoder detects a
direct connection to a DM NVX decoder or a connection to a 1000BASE-T switch.
Similarly, a 1000BASE-T port of a DM NVX decoder detects a direct connection
to a DM NVX encoder or a connection to a 1000BASE-T switch. If a direct
connection between an encoder and decoder is detected, point-to-point mode is
automatically enabled.
•Disable: Disables point-to-point mode

Image Preview
NOTE: Image preview functionality is applicable to the DM-NVX-E30, DM-NVX-E30C,
DM-NVX-D30, and DM-NVX-D30C.
Image preview provides still images (thumbnails) that show the current video being
received by an input of a DM NVX transmitter or displayed by an output of a DM NVX
receiver. Still images are shown at one frame per second. Image preview supports the
maximum resolution of the source and scales the image, while maintaining the aspect
ratio. Images can be previewed in the DM NVX web interface and accessed remotely
using a web browser. The images can also be previewed on a Crestron touch screen or
third-party interface.
To configure image preview, use the web interface or SIMPL Windows as discussed in the
following sections.

the following format:
<base file name>_<vertical resolution>px.<extension>
•<base file name> is the prefix assigned to the image preview followed by
an underscore. If the default base file name of preview is changed, clicking
the table updates the base name in the table.
•<vertical resolution> is the height of the image in pixels (px).
• <extension> is the file format of the image. The default file extension
is .jpeg.
For example, using the default base file name, which is preview, and a JPEG
image with a vertical resolution of 240 pixels, the file name of the image
preview is preview_240px.jpeg.
