DM NVX® technology transports ultra high‑definition 4K60 4:4:4 video over standard Gigabit Ethernet with no perceptible latency or loss of quality. Using standard network switches and CAT5e UTP wiring, a DM NVX system delivers a high‑performance virtual matrix routing solution for any enterprise or campus‑wide 4K content distribution application. DM NVX technology ensures the ultimate in picture quality and compatibility for all of today’s varied media sources.1
The Crestron® DM-NVX-D80-IOAV is a compact AV over IP decoder that functions as a receiver. Compatible with the Intel® Open Pluggable Specification (OPS), the DM-NVX-D80-IOAV is equipped with an OPS port and is designed for installation into the OPS slot of an OPS‑supported display. The OPS port enables the DM-NVX-D80-IOAV to receive power from the display and to feed AV and control signals to the display. The OPS port also routes USB 2.0 signals between USB peripheral and host devices.
Features of the DM-NVX-D80-IOAV also include secure web‑based control and management, AES transmit and receive capability, and copper Ethernet connectivity. The DM-NVX-D80-IOAV provides an affordable solution for a DM NVX network AV installation of any size.

Real‑Time 4K60 Video Distribution
Engineered for demanding conference room and classroom applications, DM NVX technology ensures real‑time, full‑motion 4K60 video performance for the presentation of multimedia, videoconferencing, and live camera images. Interactive functions such as gameplay and the use of a mouse are fluid and natural.
A DM NVX system is engineered for stability and ultimate reliability. Line‑synchronized outputs ensure perfect synchronization of content across multiple displays for applications such as digital signage. Variable Multicast TTL (Time To Live) enables traversing multiple network routers for optimal flexibility.
Pixel Perfect Processing Technology
A DM NVX system incorporates Pixel Perfect Processing technology, which provides flawless video transport in all applications. The DM-NVX-D80-IOAV can decode a video signal 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 (display dependent).
Using advanced security features and protocols such as 802.1X authentication, Active Directory® credential management, AES‑128 content encryption, PKI authentication, TLS, SSH, and HTTPS, a DM NVX system delivers a true enterprise‑grade network AV solution engineered to fulfill demanding IT policies.
OPS Decoder Functionality
The DM-NVX-D80-IOAV is a decoder that receives a signal from a DM NVX encoder. The OPS port of the DM-NVX-D80-IOAV feeds the signal to an OPS-supported display. The DM‑NVX‑D80‑IOAV can quickly and easily switch among multiple encoders on the network. Compatible with any DM NVX product that can function as an encoder, the DM‑NVX‑D80‑IOAV can be used in any DM NVX network AV design.
NOTE: The DM-NVX-D80-IOAV does not support video scaling.
An image can be uploaded to the DM-NVX-D80-IOAV for use as a background image on a display whenever active video content is not being displayed. Supported image file types are .jpeg, ,jpg,, and .png. The supported maximum resolution of an image is 3840x2160 pixels. Up to 20 image files can be uploaded for a total storage capacity of up to 100 MB.
7.1 Surround Sound Audio
DM NVX technology supports the lossless transport of 7.1 surround sound audio signals, including Dolby® TrueHD, Dolby Atmos®, DTS HD®, DTS:X®, and uncompressed linear PCM.
AES67 Audio Embedding and De-embedding
AES67 support allows the selected audio source to be transmitted as a 2-channel AES67 audio stream while another 2‑channel AES67 audio stream is received from a Crestron DSP or other third-party device and combined with the video signal. The received AES67 audio stream can be combined with the video and then output via the HDMI output and analog audio output.
NOTE: An AES67 audio stream that is received by a DM NVX endpoint cannot be transmitted from that endpoint.
Copper Ethernet Connectivity
The DM-NVX-D80-IOAV includes one RJ-45 1000BASE‑T Ethernet port.1

, Doc. 7977.
Automatic Point-to-Point Connectivity
Point-to-point connectivity enables the DM-NVX-D80-IOAV to be connected directly to a DM NVX 4K60 4:4:4 encoder to stream video, audio, and USB signals. Rather than being connected to an Ethernet switch, the 1000BASE-T Ethernet port of the decoder is connected directly to a 1000BASE-T port of an encoder.
By default, point-to-point mode automatically detects whether the DM-NVX-D80-IOAV is connected directly to a
DM NVX 4K60 4:4:4 encoder or to a 1000BASE-T switch. When a direct connection between the DM-NVX-D80-IOAV and an encoder is detected, the devices operate in point-to-point mode without the need for additional configuration; however, a control system is required for CEC (Consumer Electronics Control) and RS-232 control.
USB 2.0 and KVM Signal Extension and Routing
DM NVX technology supports the extension of USB signals, which can be switched and routed alongside the AV signal or separately via a control system. The OPS port of the DM-NVX-D80-IOAV includes USB 2.0 host port functionality, enabling the DM-NVX-D80-IOAV to function as a remote extender. The OPS port receives a USB signal from a KVM (keyboard, video, and mouse) device or other type of USB peripheral device.2
The USB signal is transported over the network to the USB 2.0 device port of a DM NVX device, which functions as the local extender and sends the USB signal to a USB host device (for example, a computer).
For OPS-supported displays with touch screen capability, the OPS port of the DM-NVX-D80-IOAV routes USB signals from the touch screen to a computer. For OPS-supported displays equipped with USB ports that connect to USB peripheral devices, the OPS port of the DM‑NVX-D80-IOAV routes signals from the USB peripheral devices to host devices.3
USB 2.0 data transport can be configured for Layer 2 or Layer 3. For the DM-NVX-D80-IOAV, Layer 2 supports USB signal extension in point-to-point and multipoint applications.4
USB signals can be routed from up to seven remote DM-NVX-D80-IOAV endpoints to a single local DM NVX encoder endpoint. For the DM-NVX-D80-IOAV, Layer 2 also supports the Crestron USB-EXT-DM-LOCALand USB-NX2 (LOCAL or REMOTE) devices, which can be used in locations that do not include DM NVX endpoints. USB signals can be routed between DM NVX and USB‑EXT‑DM or USB-NX2 devices under the management of a control system.
USB 2.0 Layer 3 data transport supports USB signal extension in DM NVX point-to-point applications across VLANs. USB-EXT-DM and USB-NX2 devices do not support Layer 3.
Device Control via RS-232 and CEC
Under the management of a control system, the OPS port of the DM-NVX-D80-IOAV provides RS‑232 and CEC control of an OPS-supported display.
RS-232 and CEC control can also enable the display device to be turned on or off automatically without the use of a control system.
Setup of the DM-NVX-D80-IOAV is accomplished by using a web browser. Full control and monitoring of the device is enabled through integration with a control system or with a DM NVX Director® virtual switching appliance.
Streamlined Management Using DM NVX Director Virtual Switching Appliances
For applications that are small to moderate in size, a network of DM NVX endpoints can be configured and controlled with the use of a control system. For larger enterprise and campus‑wide signal routing applications, adding a DM NVX Director virtual switching appliance (DM-NVX-DIR-80
, or DM-NVX-DIR-ENT
) enhances and streamlines the entire configuration and control process. A DM NVX Director appliance provides a central point of management and enables the creation of multiple virtual matrix switchers through one easy‑to‑use web‑based portal.
Installation into OPS-Supported Display
The DM-NVX-D80-IOAV can be easily installed into the OPS slot of a display, enabling the display to be mounted flush to a wall. The DM-NVX-D80-IOAV is powered by the display, eliminating the need for an external power supply. In addition, no HDMI, serial, and USB cables are required for the DM-NVX-D80-IOAV.
