  • Stream Type: Select either Pixel Perfect Processing (if transmitting to other DM NVX 4K60 4:4:4 capable endpoints) or DM‑NVX‑D10/D20 (if transmitting to a decoder in the D10/D20/D200 family of DM NVX decoders).

  • Multicast Address: Sets the multicast address of the outgoing stream.

    • The secondary audio stream from the DM NVX device will consume the next multicast address above the value entered here. For example, a Multicast Address of 239.10.0.1 will result in a secondary audio stream address of 239.10.0.2.

    • If Multiview is enabled, a third multicast address will be consumed at the next value above the audio stream. For example, a Multicast Address of 239.10.0.1 will result in a secondary audio stream address of 239.10.0.2 and a Multiview stream address of 239.10.0.3. Multiview receivers must subscribe to this third stream to include this transmitter's video signal in a Multiview output.

    CAUTION: Ensure the value entered for Multicast Address is unique on the network. Duplicate multicast addresses will result in traffic collision and downstream receivers will fail to receive content. Also ensure that unique addresses are available for the secondary audio stream and Multiview stream (if enabled).

    NOTES:

    • DM NVX devices can have a multicast transmit address anywhere in the range from 239.0.0.0 to 239.127.255.255. Starting at 239.1.0.0 is recommended to avoid common multicast MAC address conflicts.

    • DM NAX audio-over-IP devices use a multicast range from 239.8.0.1 to 239.127.255.255.

  • Device Name: Displays the name of the DM NVX device. A custom name can also be entered in this text box. By default, this will match the hostname.

  • Multi‑View: Enables or disables the Multiview feature. Multi‑View is disabled by default. With Multi‑View enabled, the encoder transmits an additional video stream that can only be received by Multiview capable decoders.

    CAUTION: Enabling Multiview will consume an additional multicast transmit address. While assigning multicast addresses to devices on the network, ensure that three addresses are reserved for each Multiview transmitter. Refer to the Multicast Address field above for more information.

    To enable Multiview:

    1. Set the Multi‑View toggle to the right. A Reboot confirmation dialog box will appear.

    2. Select Yes, Reboot Now to reboot the device or select No to cancel the change. If Yes, Reboot Now was selected, a Reboot status box will appear.

    3. Wait for the device to fully reboot before attempting to log in to the user interface. Once the reboot has completed, a Multiview video stream can begin transmitting from the device.

  • Stream Location: Displays the network location of the stream.

  • Status: Displays the status of the network stream (for example, Stream starting, Stream started, or Stream stopped).

  • Resolution: Displays the resolution of the outgoing stream.

  • Preview: Displays a preview thumbnail of the stream; the thumbnail refreshes once per second.

DM NAX (AES67) Audio

DM NVX devices natively support DM NAX® audio-over-IP technology, which is built off the standards of AES67. AES67 support allows a selected audio source to be transmitted as a 2-channel AES67 stream while another 2-channel AES67 audio stream is received from another AES67-capable device or Crestron DM NAX device.

Use the DM NAX (AES67) Audio accordion to configure the DM NAX audio-over-IP transmit and receive streams of the DM NVX device.

To configure the DM NAX (AES67) Transmit stream:

  1. Select a stream addressing mode from the Mode drop-down:

    • Automatic adds 1 to the outgoing video stream multicast address to generate the DM NAX transmit multicast address. For example, if the video multicast address is 239.8.0.1, the DM NAX (AES67) multicast address is automatically set to 239.8.0.2.

    • Manual requires the multicast address of the transmitting DM NAX stream to be set manually. Selecting Manual enables the Multicast Address and Port text entry fields.

    • Disabled turns off DM NAX transmission from the DM NVX device.

  2. Set a custom session name in the Session Name text entry field. This is similar to setting a hostname for an IP address on the LAN. The session name will appear in addition to the multicast address when the DM NAX audio-over-IP stream is discovered on the network.

  3. If the Mode is set to Manual, enter custom values in the Multicast Address and Port text entry fields.

  4. Set the Auto Initiation toggle to the right to enable or left to disable automatic initiation of the DM NAX transmit stream. With Auto Initiation enabled, the stream will automatically start when valid stream parameters are set. By default, Auto Initiation is enabled.

  3. Select a USB HID Capture Exit Mode hot key option from the drop‑down. This is the HID keyboard key (or combination of keys) that will exit the USB Hotkey SIMPL symbol from HID capture mode.

    1. If Custom was selected from the drop‑down, enter the serial data for the key (or keys) into the Raw Hex Key text entry. This data can be pulled from the USB Hotkey SIMPL symbol's Message_F serial join via the SIMPL Debugger utility in Crestron Toolbox™ software.

NOTE: While in USB HID Capture Mode, all HID data from a connected keyboard is output as raw hex data from the SIMPL symbol's Message_F serial join instead of being forwarded to a connected Host device.

IR Ports

NOTE: This accordion is not available on card‑based models.

The IR Ports accordion allows custom IR files containing device commands to be uploaded to the DM NVX device for each IR connector. Custom IR files can be generated via the Device Learner utility within Crestron Toolbox software. Each IR port can hold only one IR file at a time. IR files must be loaded to each port individually.

To upload an IR file to a given IR port:

  1. Select Load IR File.

  2. In the File Upload window that appears, select + Browse.

  3. Locate and select the desired IR file, then select Open. The selected file name is displayed.

  4. Select Load, then wait for the progress bar to complete and for OK to become selectable.

  5. Select OK. The IR file is now loaded to the IR port.

Once the IR file is uploaded, its filename will appear next to the IR port it was uploaded to. A read-only table showing all included commands will also appear and populate.

To delete an IR file from a given IR port, select Delete IR File.

Port Selection

The Port Selection feature allows the device's internal network traffic to be managed and segregated based on traffic type. Internal VLANs are used to segment device management, video, AES67, and USB traffic to discrete Ethernet ports. With Port Selection disabled, the additional Ethernet ports of the DM NVX device can be used as courtesy ports to extend the connected LAN to a local network device. With Port Selection enabled on all DM NVX devices on a network, traffic types can be physically separated from the control network onto dedicated networks.

To configure Port Selection:

  1. Set the Port Selection toggle to the right to enable Port Selection. Set the toggle to the left to disable Port Selection. By default, Port Selection is disabled.

  2. With Port Selection enabled:

    1. Select an Ethernet port from the Management drop-down to designate it to handle network traffic relating to device configuration and connection to a control system.

    2. Select an Ethernet port from the Video drop-down to designate it to handle the DM NVX AV-over-IP streaming network traffic.

    3. Select an Ethernet port from the Audio/NAX drop-down to designate it to handle audio-over-IP streaming network traffic.

      NOTE: The audio signal in the primary DM NVX AV-over-IP stream will still traverse the port designated by the Video drop-down. The Audio/NAX drop-down only designates the port for the secondary audio stream.

    4. Select an Ethernet port from the USB drop-down to designate it to handle USB-over-Ethernet traffic.

  3. Select Save to apply the new settings.

    NOTE: Changes to Port Selection will require a device reboot.

Test Pattern Generator

The Test Pattern Generator accordion contains settings for enabling various video test patterns to replace the DM NVX AV-over-IP video output signal.

NOTE: The Test Pattern Generator accordion is only available when the device is set to Transmitter mode.

To set a test pattern:

  1. Use the Test Pattern drop-down to select an available pattern from among Off, SMPTE ColorBars, Black, White, Vertical Lines, Grid, Color Bars, Gray Gradient, RGB Gradient, and Frequency Adjust. Refer to the table below for a reference of each pattern.

  2. Use the Resolution drop-down to select a resolution for the selected test patten.
