        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 mousing and game play are fluid and natural.

        A DM NVX system is engineered for stability and reliability. Forward Error Correction ensures that AV data is delivered without interruption. Line‑synchronized outputs ensure perfect synchronization of content across multiple displays for applications such as digital signage and video walls. 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. Depending on the operating mode, the DM‑NVX‑351 can encode or 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.

        Enterprise‑Grade Security
        A secure AV network ensures reliability by protecting the integrity and privacy of the content. Every device on the network must be secure to protect against intrusions. 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.

        Encoder and Decoder in One
        In a single compact device, the DM‑NVX‑351 is configurable to operate as either a network AV encoder or decoder:

        • As an encoder, the DM‑NVX‑351 allows the HDMI signal of a laptop computer, camera, or other media source to be transmitted over the network to one or many decoders.1
        • As a decoder, the DM‑NVX‑351 receives the signal from a DM NVX encoder and feeds it to a display device via the HDMI output. The decoder can quickly and easily switch between multiple encoders on the network alongside locally connected HDMI sources.1

        The DM‑NVX‑351 provides a versatile, cost‑effective solution for applications that require encoder and decoder operating modes in one device. The operating mode can be reconfigured dynamically in under 1 minute via a control system or web browser or can be changed by using the onboard Setup button.

        2x1 HDMI® Auto‑Switcher
        The DM‑NVX‑351 includes two HDMI inputs. Switching between the two inputs can be performed automatically using auto‑switching mode, programmatically via a control system, manually using the onboard Input Select button, or through a computer using a web browser. When used as a decoder mounted behind a typical conference room display device, the HDMI inputs provide a convenient way to connect a Crestron AirMedia® presentation gateway, videoconferencing codec, or mini computer.1

        HDMI Output with 4K60 4:4:4 Scaler
        When the DM‑NVX‑351 is configured as a decoder, the HDMI output feeds the decoded signal to the HDMI input of a local display device, switcher, or other equipment. The built‑in scaler ensures an optimal image, scaling the encoded source resolution up or down to match the native resolution of the display device. When the DM‑NVX‑351 is configured as an encoder, the HDMI output can be used to feed a local display, confidence monitor, or audio system.1, 4

        Copper or Fiber LAN Connectivity
        The DM‑NVX‑351 includes two RJ-45 1000Base-T LAN ports. Either port can be used as the primary LAN connection, allowing the other port to provide a network connection for an AirMedia gateway, display device, or other local device. These ports can also be used to daisy‑chain multiple endpoints feeding a single‑source video wall or individual displays that show the same video image.LAN port 1 is also capable of receiving power from a Crestron power injector (DM‑PSU‑ULTRA‑MIDSPAN), a UPOE compliant Ethernet switch, or an approved third‑party PSE.2, 5

        Connection to a fiber-optic network is facilitated by inserting an appropriate SFP transceiver module (Crestron SFP‑1G Series) into the SFP port of the DM‑NVX‑351. A selection of modules is offered to accommodate various multimode and single‑mode fiber types.3

        A DM NVX system can be deployed on an existing corporate or campus network or on a dedicated network. For information about network requirements and guidelines, refer to the DM NVX System Design Guide, Doc. 7977, at https://www.crestron.com/nvx.

        Video Wall Processing
        A video wall composed of up to 64 individual displays can be configured using multiple DM‑NVX‑35x(C) Series endpoints. Each endpoint provides fully adjustable zoom capability and bezel compensation to accommodate a range of video wall configurations and display types. One DM-NVX-35x(C) endpoint is required per display, supporting configurations of up to eight wide by eight high.

        Text Overlay
        The ability to display dynamic or fixed text on screen provides a means to label the video source or to display special instructions, schedules, announcements, alerts, and other messaging.

        7.1 Surround Sound Audio with Downmixing
        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. The DM‑NVX‑351 can decode the incoming multichannel surround sound signal, whether from the network or an HDMI input, and downmix that signal to stereo. The stereo downmix signal is automatically routed to the onboard analog output6, while the HDMI output can be configured to output either stereo or multichannel signals. As an encoder, the DM‑NVX‑351 distributes both stereo and multichannel signals simultaneously over the network, allowing either signal to be selected at any decoder on the network.

        Analog Audio Embedding or De‑embedding
        A balanced stereo analog audio port is included, which can be configured as either an input or output. As an input, the port allows a stereo audio source to be connected and combined with the video signal from either HDMI input or the incoming network video stream. As an output, the port can provide a stereo line‑level signal to feed a local sound system or soundbar. The output volume is adjustable via a control system or web browser.6

        Breakaway Audio
        A DM NVX decoder can select and combine separate video and audio signals from two different inputs—even two different encoders. There are two exceptions: 1) Signals cannot be combined between the two onboard HDMI inputs, and 2) Combining signals from two separate encoders is limited to 2‑channel stereo audio.7

        USB 2.0 and KVM Integration
        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. USB 2.0 HOST and DEVICE ports are provided on the DM‑NVX‑351, allowing a USB mouse, keyboard, or other peripheral device to be connected to a remote endpoint and routed to a computer or other host at the local endpoint. In addition to KVM switch functionality, various types of USB peripherals are supported, including whiteboards, touch screens, game controllers, cameras, mobile devices, headsets, and flash drives.8

        USB 2.0 data transport can be configured for Layer 2 or Layer 3. Layer 2 supports USB signal extension in point-to-point and multipoint applications. USB signals can be routed from the HOST port of up to seven remote DM NVX endpoints to the DEVICE port of a single local DM NVX endpoint. Layer 2 also supports Crestron USB over Ethernet Extender Modules (USB‑EXT‑DM‑LOCAL or USB‑EXT‑DM‑REMOTE), 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 devices under the management of a control system.9

        USB 2.0 Layer 3 data transport supports USB signal extension in DM NVX point-to-point applications across VLANs. Layer 3 support is not applicable to USB-EXT-DM devices.

        Device Controller
        The DM‑NVX‑351 includes built‑in RS‑232 and IR ports for control of the connected display, camera, or other devices under the management of a control system. Additional control capability is provided by CEC (Consumer Electronics Control) over the HDMI connections. Under the management of a control system, the DM‑NVX‑351 can control the display and source devices, potentially eliminating the need for dedicated serial cables or IR emitters.10

        Web‑Based Setup
        Setup of the DM‑NVX‑351 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.

        Compatibility with 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‑XIO‑DIR‑80, DM‑XIO‑DIR‑160, or DM‑XIO‑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.

        Crestron XiO Cloud™ Service Support
        The DM‑NVX‑351 is compatible with the Crestron XiO Cloud service, which is an IoT (Internet of Things) based platform for remotely provisioning, monitoring, and managing Crestron devices across an enterprise or an entire client base. The service enables installers and IT managers to deploy and manage thousands of devices in the amount of time it would ordinarily take to manage a single device. For more information, visit www.crestron.com/xiocloud.

        Low‑Profile Installation
        The DM‑NVX‑351 mounts conveniently to a flat surface or rack rail, and fits easily behind a flat panel display, above a ceiling‑mounted projector, beneath a tabletop, or inside a lectern, AV cart, or equipment cabinet. All connectors and LED indicators are positioned on the front and rear of the device, offering optimal access and visibility for a clean, serviceable installation. Power is provided using the included 100‑240 V universal power pack, an optional power injector (Crestron DM‑PSU‑ULTRA‑MIDSPAN), a UPOE compliant Ethernet switch, or an approved third‑party PSE.5

        1. 4K60 4:4:4 performance and HDR support require the use of HDMI cables and couplers with a minimum TMDS bandwidth of 18 Gbps. If 4K60 4:2:0 or 4K30 4:4:4 performance is acceptable, cables and couplers with a minimum bandwidth of 10.2 Gbps may be used. Bandwidth loss is cumulative; therefore performance may be reduced when inserting multiple cables and couplers inline.
        2. The minimum cable required for DM NVX over 1000Base‑T Ethernet (copper) is unshielded CAT5e. All LAN ports on the DM‑NVX‑351 are for connection to an Ethernet network or device; they cannot be connected to the DM® ports of other Crestron devices.
        3. The use of a fiber-optic LAN port requires the purchase of a Crestron SFP‑1G Series transceiver module (sold separately). All LAN ports on the DM‑NVX‑351 are for connection to an Ethernet network or device; they cannot be connected to the DM ports of other Crestron devices.
        4. When the DM‑NVX‑351 is in encoder mode, the HDMI output resolution is matched to the resolution of the encoded source.
        5. Refer to the "Power" section for approved powering options.
        6. The analog audio port can function as an input or output—not both.
        7. Audio from one onboard HDMI input cannot be combined with video from the other onboard HDMI input. Combining audio from one encoder with video from another encoder is possible using the secondary 2‑channel audio stream only. Multichannel audio from one encoder cannot be combined with video from another encoder.
        8. The DM‑NVX‑351 can be configured to accept the connection of a USB device or a USB host—not both. Crestron DM NVX products are engineered to deliver maximum compatibility with the widest possible range of USB products. Crestron does not guarantee that all USB products are compatible with DM NVX products. Consult the DM NVX System Design Guide, Doc. 7977, for USB bandwidth considerations.
        9. DM NVX devices are not compatible with the USB HID signal extender technology found in other Crestron DM products.
        10. Device control via RS‑232, IR, CEC, or Ethernet requires integration with a Crestron 3‑Series or later control system.
        11. The minimum bit rate for 4K60 video is 350 Mbps. A bit rate below 350 Mbps may display a black screen.
        12. 3D formats are not supported.

        1. 4K60 4:4:4 performance and HDR support require the use of HDMI cables and couplers with a minimum TMDS bandwidth of 18 Gbps. If 4K60 4:2:0 or 4K30 4:4:4 performance is acceptable, cables and couplers with a minimum bandwidth of 10.2 Gbps may be used. Bandwidth loss is cumulative; therefore performance may be reduced when inserting multiple cables and couplers inline.
        2. The minimum cable required for DM NVX over 1000Base‑T Ethernet (copper) is unshielded CAT5e. All LAN ports on the DM‑NVX‑351 are for connection to an Ethernet network or device; they cannot be connected to the DM® ports of other Crestron devices.
        3. The use of a fiber-optic LAN port requires the purchase of a Crestron SFP‑1G Series transceiver module (sold separately). All LAN ports on the DM‑NVX‑351 are for connection to an Ethernet network or device; they cannot be connected to the DM ports of other Crestron devices.
        4. When the DM‑NVX‑351 is in encoder mode, the HDMI output resolution is matched to the resolution of the encoded source.
        5. Refer to the "Power" section for approved powering options.
        6. The analog audio port can function as an input or output—not both.
        7. Audio from one onboard HDMI input cannot be combined with video from the other onboard HDMI input. Combining audio from one encoder with video from another encoder is possible using the secondary 2‑channel audio stream only. Multichannel audio from one encoder cannot be combined with video from another encoder.
        8. The DM‑NVX‑351 can be configured to accept the connection of a USB device or a USB host—not both. Crestron DM NVX products are engineered to deliver maximum compatibility with the widest possible range of USB products. Crestron does not guarantee that all USB products are compatible with DM NVX products. Consult the DM NVX System Design Guide, Doc. 7977, for USB bandwidth considerations.
        9. DM NVX devices are not compatible with the USB HID signal extender technology found in other Crestron DM products.
        10. Device control via RS‑232, IR, CEC, or Ethernet requires integration with a Crestron 3‑Series or later control system.
        11. The minimum bit rate for 4K60 video is 350 Mbps. A bit rate below 350 Mbps may display a black screen.
        12. 3D formats are not supported.
        13. HDMI connections require an appropriate adapter or interface cable to accommodate a DVI or Dual‑Mode DisplayPort signal. CBL‑HD‑DVI interface cables are available separately.
