    B --> C["Line Mode"]
    C --> D["All Input Mode"]
    D -->|Feedback| A

Figure 5 - Audio Mode Screen Flow The audio modes will accessed based on the order shown in Figure 5. If any of the configurable modes are disabled from the configuration software, then those modes will simply be skipped over to the next available mode. In the audio modes, the Volume +/- buttons are always used to adjust the speaker and headphone volume. The volume range is 1 to 10. Additionally, the speaker Mute button will always operate as an audio mute function for the attached headphone and speaker. The mute buttons indicate mute state by lighting their associated red LED when mute is. When headphones are plugged into the unDNEMO, the internal speaker is automatically disabled until the headphones are removed. \*Note: By default, only the Net Mode is enabled, pressing the "Select" button when only Net mode is enabled will result in the message "Unsupported Function" to be shown briefly on the display.

2.2.1 - Net Mode

The primary operating mode for audio monitoring is the Net Mode. In this mode Dante audio channels may be selected by the user from the front panel controls for simple and efficient audio monitoring applications. When in this mode the display will indicate the channel number that has been assigned using the unIFY Control Panel Software in the top area of the display and the configured channel name for the selected channel in the central viewing area of the displayed.  Figure 8 - Brightness Control If Dante TX audio features are enabled within the unIFY Control Panel software for the unDNEMO, the line input audio will also be routed to the first and second Dante audio transmit channels of the device for audio bridging applications. Dante Controller or another 3 ^rd party application must be used to route the audio to the intended Dante receive device.

2.2.4 - All Input Mode

The all input mode allows the user to simultaneously monitor a mix of the audio from the selected Dante network audio channel, the line level analog input and the USB audio input. This is useful in applications that require monitoring audio from multiple, independent sources simultaneously.  Figure 10 - All Input Mode Audio Routing In the All input mode, the USB, and Line input sources are indicated with a checkmark on the title bar of the display when they are connected. The main content area of the screen shows the channel name of the network input audio, with the active channel number shown in the center of the title bar. The channel Up/Down buttons are used to navigate the network audio channel selection just as they operate in the Net Mode. The All Input mode does not support any Dante TX audio routing capabilities.

2.3 - Menu Mode Navigation

The unDNEMO features a number of menu screens for showing status and basic device configuration. The menu mode access is also a configurable option that can be disabled for applications where the end user may only require limited access to the devices features. By default, the menu mode access is disabled and must first be enabled from the configuration software. Once enabled, the menu mode may be entered by pressing the "Menu" button. While in menu mode, the display will indicate MENU: in the upper left of the screen. To exit menu mode, press the MENU button again to toggle back to the audio modes.

The MAC address screen shows the device MAC address and can also be identified by referencing the label placed on the bottom of the unit. The IP address screen shows the current IP address of the device. To change the IP address settings, use Dante Controller or other configuration software that supports general networking configuration for Dante devices.  Figure 12 - Brightness Control  Figure 16 - Device Info: IP

3 - System Setup

\*Note: All Attero Tech products are tested using UTP cabling and it is recommended that UTP cabling be used when installing them. STP cabling can be used for installation though care must be taken not introduce grounding issues into the system by doing so.

3.1 - Single Port Mode

The unDNEMO is configured for single port mode by default. In this mode the second, non-PoE powered Ethernet port is disabled to provide security for applications that require restricted access to the network. For a device that has been altered from its factory defaults, single port mode may be re-enabled via Dante Controller. Select "Single Port" from the Network Config tab within the Device View window. This will require a reboot of the device.

3.2 - Daisy Chain Deployment

The unDNEMO can be deployed in standard Ethernet networks with and without external switching hardware. To enable this switched mode, select "Dual Port - Switched" from the Network Config tab within the Device View window. This will require a reboot of the device. The first example below shows the Dante port of an audio DSP connected to the Ethernet (Dante) port of the unDNEMO at supervisor station 1. Due to the integrated Gigabit Ethernet switch, other unDNEMO devices can be daisy-chained together to eliminate the need for any external Ethernet switches. \*Note: Each unDNEMO would require a local 24V DC power supply connection. Daisy chain of PoE is not possible.

Figure 17 - Daisy Chain Deployment \*NOTE: It is not recommended to connect high channel count Dante devices to the end of any daisy-chain segment. The daisy chain feature is intended to ease deployment in situations where additional Ethernet switches may be obtrusive and difficult to install. The daisy-chain feature is not intended to be use as a high bandwidth connection between two or more Ethernet switches to bridge network segments.

3.3 - PoE Deployment

The unDNEMO supports PoE 802.3af power on the left-most Ethernet port labeled "PoE+Data" on the rear panel of the unit. To utilize PoE, connect CAT-5e or better cabling between the PoE port of the unDNEMO and an 802.3af compliant PoE Ethernet switch or midspan power injector. In this configuration, PoE cannot be daisy-chained and each device requires a CAT-5 connection back to the Ethernet switch. The following diagram shows the unDNEMO devices used with an Ethernet switch providing both PoE and Dante connections, with audio sourced from an Attero Tech unD4I 4-channel analog input to Dante interface.

3.4 - Dante Configuration Notes

In general, there is little to no additional configuration required to successfully utilize the unDNEMO devices in a Dante network other than the initial channel configuration and setup required using the unIFY Control Panel software. However, if the unDNEMO is utilized in a Dante network with audio transmit channels that are already configured to transmit to one or more Dante receive devices, the potential exists that the unDNEMO will not be able to subscribe to the Dante transmitter as the number of unicast receivers assigned to transmitting device and channel may be exceeded. To mitigate this issue, the desired audio channels may be placed in multicast flows such that there is no limit on the number of Dante receive devices. In systems where a large number of unDNEMO devices are utilized, this is the recommended practice to mitigate these channel subscription limitations that exist when only using unicast Dante a audio transmission. Care should always be taken to understand how much multicast bandwidth exists on the Dante network, and utilize the tools within Dante Controller to identify any networking and Dante configuration issues.

3.5- Factory Reset

The unDNEMO and unDNEMO-BT have a factory reset option. Using it will reset all the devices parameters back to their factory defaults including all the Dante® settings such as device name, channel names as well as the device settings such as input select. The devices IP address mode is also reset back to getting a dynamic IP. Access to the factory reset button is through a small circular hole on the rear of the unit between the USB and PoE Ethernet connector. To use the factory reset, insert a small screwdriver or paperclip into the hole to activate the factory reset switch. There should be a noticeable "click" when it's activated. Hold the switch in for approximately 10 seconds then release. If the factory reset was successful, a few seconds after releasing the switch, the unit will reset itself.
