Please refer to the SDI AoIP Node Quick Start Guide for installation and setup instructions.

Setting IP Addresses

The IP section of the System Menu contains the fields and controls necessary to set up networking for both the Control port and the AES67 port. The controls for both ports are identical.

The Active indicator (B) lights green for when the ports are active.

To make changes to the settings, click on the Edit button (D), which is immediately replaced with Cancel and Apply buttons.

DHCP is enabled by default on the Control port. Toggle the Use DHCP switch (A) to turn DHCP on or off. When DHCP is disabled, you may set a static IP address by entering the appropriate values into the IP address, Net Mask, and Gateway fields (C).

Click Cancel to discard any changes or Apply to save them.

If either of the two Ethernet ports will not be used, the unused port must be configured as follows:

• Do not connect the unused port to a network switch

• Using the steps above for Control port setup, navigate to the IP Configuration screen of the unused port

• Set “Use DHCP” to “Yes”

• Highlight and select “Update”

Network configuration can also be accomplished via the front panel as outlined in the Quick Start Guide.

Sync, QoS, and PTP Settings

As previously mentioned, when the SDI AoIP Node is set up to use AES67 audio at its input, output, or both, it must slave to an external PTP clock for reference.

The Slave Only button (A) must be enabled and the Domain Number must be set for the correct PTP domain. Valid values are 0 - 127. The AES67 PTP profile uses 0; the SMPTE PTP profile uses 127.

SDI AoIP Node Front Panel

SDI AoIP Node front panel features include:

• Four status LEDs indicating the status of each power supply (1A, 1B), the overall status of the unit (1C), and sync for the reference clock (1D)

• A color LCD display to show status and basic configuration parameters (1E)

• A five-button navigation cluster with Left, Right, Up, and Down arrows plus a green “OK” button (1F)

The front panel is used for the initial setup and configuration including setting the IP address of the Ethernet ports. Additional configuration is accomplished via the remote user interface.

Inputs and Outputs

SDI I/O

SDI AoIP Node can access any of the eight audio pairs carried on each of the two available incoming HD- or SD-SDI streams, pair shuffle to the two HD- or SD-SDI outputs, or route audio to an AoIP stream.

AES67 I/O

Incoming AES67 audio sources can be embedded to an SDI output, and embedded SDI outputs can in turn be sent out as AES67 streams.

Reference Clocking and Sample Rate Converters

Having a firm grasp of clock sync (reference) requirements is critical to the successful operation of the SDI AoIP Node.

Sample Rate Converters (SRCs) are provided on each of the two SDI input and output paths. There are no SRCs in the AES67 path.

Reference clock source options include:

• Internal 48kHz

• SDI Input 1

• SDI Input 2

• PTP v2 per AES67-2015

If the SDI AoIP Node is used strictly for the purpose of pair shuffling between SDI inputs and outputs, it can be clocked to the reference present on either SDI input signal.

Reference Clock

If you will be using the SDI AoIP Node simply to de-embed, pair shuffle, route, and re-embed only SDI signals and will not be connecting it to an AoIP network, navigate to the I/O Menu and choose "SDI1" or "SDI2" as your reference in the Reference clock dropdown (1A). If desired, you may choose a secondary reference clock as a backup should the unit lose its reference from the primary clock source.

If you are connecting to an AoIP network with a Master PTP Clock, you must choose "AES67/PTP" as your clock reference.

Inputs and Outputs

SDI AoIP Node can access any of the eight audio pairs carried on each of the two available incoming HD- or SD-SDI streams, pair shuffle to the two HD- or SD-SDI outputs, or route audio to an AoIP stream.

Incoming AES67 audio sources can be embedded to an SDI output, and embedded SDI outputs can in turn be sent out as AES67 streams.

SDI I/O

The SDI 1 and SDI 2 connections each have their own routing controls under the I/O Menu. The controls for each are identical.

Each of the SDI input pairs is simply labeled according to its pair number ("SDI In 1/2") but can be renamed by clicking on the Label field (2A), typing in the desired name, then clicking on the green checkmark to save.

SDI output routing is set by the SDI Out dropdown (2C) for each pair. Pair shuffling within or between SDI inputs is supported, or any available AES67 source may be selected.

All Sample Rate Converters (SRCs) on both the SDI Inputs and Outputs are enabled by default but can be disabled on a per-pair basis using the Input SRC (2B) and Output SRC (2D) switches. Doing so does lower throughput latency slightly, but there is no disadvantage to leaving them enabled. In fact, if there are any anticipated reference clock changes (either intentional or unplanned) it is safer to leave them enabled.

AES67 I/O

Settings for the AES67 I/O are found under the I/O Menu.

To set an AES67 input, enter the Livewire channel number or multicast address of the AoIP source directly in the Address field (3A) or use the channel picker (3B) to see a list of available sources. Livewire channels will automatically resolve to their corresponding multicast addresses.

Use the AES67 Output dropdown (3D) to select any audio pair from either SDI input or any AES67 input pair. Assign the output a Livewire channel number or a multicast address in the Address field (3E). As with the input, Livewire channel numbers will automatically resolve to their corresponding multicast addresses.

GPI/O

SDI AoIP Node features a rear-panel DB-15 connector for momentary GPIO contact closures. This feature will be implemented in future software versions and is not currently supported in V1.2.006.

GPI/O Pinout

Delays and A/V Sync

An adjustable video delay is provided in the Delays section of the I/O menu to compensate for the audio latencies in the broadcast system and to ensure correct A/V sync at the output. Each SDI path has its own Video Delay (5A), adjustable by clicking on the millisecond (ms) or microsecond (us) field, entering the desired value, then clicking the green checkmark to save.

In instances where the SDI output needs to be delayed by an even frame (the value of which will vary depending upon frame rate) simply enter that number. It may then be necessary to compensate for the difference between that time value and the latency of the unit by clicking in the Audio Delay (5B) field, entering the desired value, then clicking on the green checkmark to save.

Latency values are as follows, measured using an SDI input to an AES67 network, through the SDI AoIP Node, and to an SDI output:

• 121ms with input and output SRCs disabled

• 127ms with input and output SRCs enabled

Connecting to the SDI AoIP Node

As previously mentioned, certain settings and configurations can be accessed and performed using the front panel buttons and screen, but the SDI AoIP Node is designed to be connected to a network and operated through its HTML-5 web-based interface.

No special client software is required, and the HTML-5-based GUI is device-, operating system-, and browser agnostic. We recommend using Google Chrome or Apple Safari. The computer or tablet should be on the same network and subnet as the SDI AoIP Node.

Once the SDI AoIP Node and your computer are connected to your network, enter the IP address of the node to which you want to connect in the URL field of your browser. Once connected, the Home Screen will appear.

As you navigate through the user interface, clicking on the SDI AoIP Node logo (A) in the top left corner will always return you to this screen.

Multiple users can connect to the same ARC hardware simultaneously. Anyone connected to the unit will be able to see the information on this screen including the unit’s name (B) and physical location (C).

Additionally, all users can access the Meters screen (D) which shows loudness measurements and input/output levels for both programs. See the section "Home Screen When Logged In” below for detailed information.

The Locate Unit feature (E), which causes the front panel display of the unit to flash for easy identification in a crowded rack, can also be activated without logging in.

Additional information about installed options, clock sync, network status and IP address, power supply status, software and FPGA versions, and unit uptime are displayed to the right of the screen (F).

User Accounts and Logging In

Making modifications to the SDI AoIP Node's configuration and signal routing via the remote user interface requires logging into the unit. At this time, only one user account with one password and one level of access is supported.

Enter the default password of 1234 into the Password field (G) then click on the Log In button (H). The ability to change the password will be included in a future software update.

Home Screen When Logged In

Additional menus become visible once you are logged in. These include I/O menus (A) for the SDI and AES67 inputs and outputs, detailed system-wide information and configuration settings (B) including IP, sync, and QoS, and detailed I/O metering (C).

I/O Menu

The process for configuring inputs and outputs is covered in detail in the section on I/O Configuration and will not be duplicated here, however, an explanation of the information on the main I/O page is provided below.

Input Status and Reference Clock

The Input Status section (A) shows the sync status, signal format, and video format for both SDI inputs as well as the AES67 input. It also displays the primary and secondary reference clocks alone with their status.

The Reference Clock section (B) includes the dropdown menus for selecting the primary and secondary reference clocks and an indication of the last time the reference changed.

System Menu

The System Menu is home to the System status screen. It also contains the menus and controls for configuring the Control and AES67 Ethernet ports.

The main system screen contains a wealth of technical status information about the device hardware and software (A). Some of it relates to the overall health of the unit (such as Power Supply status and unit uptime) but most will only be required during the course of troubleshooting an issue with our support team or performing software updates.

The Unit Name and Location (B) are entered on this screen. These are “friendly” fields to be used in any way that makes sense for your particular operation. Click inside the field, type the desired information, then click on the green checkmark to save.

Clicking on the Master Unit Bypass button (C) engages a hard relay bypass that removes all internal circuits and processes from the signal path and connects each input directly to its corresponding output. This button will turn red when the SDI AoIP Node is in bypass mode. Note that this same hard relay bypass automatically engages when the unit is powered down.

Clicking on the Locate Unit button (D) will cause the front panel of this particular SDI AoIP Node to change color, making it easy to identify it amongst the dozens of them we hope will populate your racks. A second click will stop the light show. Note that enabling Locate Mode will not affect the audio.

It should come as no surprise that clicking on the Reboot Unit button (E) – wait for it – reboots the SDI AoIP Node and engages the hard relay bypass for the duration of the reboot process.

Clicking on the Reset Unit to Factory Defaults button (G) resets all parameters to the factory default state with the exception of IP settings which will be retained so that you can remotely connect to the SDI AoIP Node even after performing a reset.

If you wish to reset IP settings as well, enable the Include IP Settings in Reset button (F) prior to the reset.

Software Updates

The SDI AoIP Node has two software banks. Both can be populated with different software versions, but only one version can be active at any given time. The Active bank (H) is indicated in red. Instructions for uploading and selecting different software versions are provided along with the software when you either download it from the customer portal or website or it is provided by our customer support team.

Meters

Input meters (A) are provided for the SDI1, SDI2, and AES67 inputs. Individual bar graphs show the levels of each channel (1-16).

Likewise, Output meters (B) show the levels of each channel from the SDI1, SDI2, and AES67 outputs.
