Welcome to the Future
What is NDI®?
Your new OG4 converter card has been designed from the ground up to support the cutting edge NDI® video
transmission standard.
NDI® (Network Device Interface) is a free, high-quality, low-latency, frame-accurate standard that enables
compatible devices to communicate, deliver, and receive high denition video over your existing Gigabit Ethernet
network.
Operating bi-directionally, NDI® devices can be auto-detected, powered and controlled over the same Ethernet
cable used to send the video and audio. If you have a Gigabit network, you have a now have the potential for a
streamlined, interconnected, video production environment.
With the introduction of NDI® 5, you can now securely share network sources between remote sites anywhere in
the world - on a single network port. Even a smartphone can be a NDI® source.
Transitioning to NDI® can also occur gradually. Existing SDI signals can easily be converted to an NDI® stream and
piped where required on your network and converted back only at the neccessary SDI endpoints.
BirdDog has been on the NDI® journey since the very beginning and your OG4 converter card is just one of our
products designed to take advantage of the features and potential of NDI®.
For more information on NDI®, please refer to this page on our website.

Getting To Know Your BirdDog OG4 Converter Card
Thanks for purchasing the BirdDog OG4 converter card. This card is designed for the openGear oGx modular
frame. This AV industry rack standard makes it easy to securely install and integrate many types of processing
cards from a large variety of openGear partners.
Please take some time to read this guide and familiarize yourself with the features of your new converter.
The OG4 converter card consists of the main processing card, which is mounted inside the
openGear frame, and the rear module plate which houses the connectors for the converter.
The card is automatically powered by the frame and you can easily access the settings of the converter using either
the BirdDog WebUI, or the Ross Video Dashboard, via the frame Ethernet port. The front end of the card also
features a Reset button which clears all user conguration.

Operating your OG4 Converter Card
Operation of the OG4 Converter Card is simple and very similar to the BirdDog QUAD Converter.
Setup of your card is accomplished via the BirdDog WebUI. Once set up, you can choose to adjust the settings of
your card via the BirdDog WebUI or the Ross Dashboard.
However, rmware updates, as well as conguration of network settings such as DHCP can only be done via the
BirdDog WebUI.
Your card is supplied with a sample Ross Dashboard interface. You can custom design your own Ross Dashboard
to display whatever features you wish. Both interfaces must run on a computer that has a physical wired Ethernet
connection. Wireless connections do not allow device discovery.
Web Conguration Panel
The BirdDog web conguration panel (WebUI) allows you to interact with your converter and ofers complete
control of A/V settings and video frame rates, including restarting the video processing engine, changing
networking parameters and applying rmware updates.
Access via web browser (URL)
Your converter is congured to automatically receive a network IP address from the computer network via DHCP
(Dynamic Host Conguration Protocol). Most corporate, education and home networks have a DHCP server on the
network to allow this to occur. Usually your Internet Router provides this.
If your device receives an IP address automatically from this server (DHCP) the IP address can be discovered in
several ways, including the free BirdDog Central Lite software.
Your computer will need to have ‘Bonjour’ services loaded in order to access the unit via it’s user dened name.
Apple devices come pre-installed with Bonjour, while Windows devices need a plugin available from here.
Access without a network DHCP server
Some standalone or private networks may not have a DHCP server. After 30 seconds of waiting for an automatically
assigned IP address the device will fall back to a default address which is: 192.168.100.100.
In order to access the web conguration panel on a network which is congured to a dierent subnet, change your
computers IP address to match the BirdDog unit’s IP address range. Once you gain access to the BirdDog web
conguration panel (WebUI), choose your IP address to match the rest of the devices on your network.
For instructions on setting your computers IP address please consult your computer operating system manual or
IT support resources.
Password Management
Once you direct your web browser to the BirdUI you will need to log
in to change any settings.
Default password
The web conguration panel is secured by a user-selectable
password.
The default password is: birddog (one word, lower case).
7
Page 10
To change the password simply login using the default password, navigate to the network tab in the web interface,
and select change password.
It is recommended to change this password in a network environment where your device is shared with other users
(e.g., not private). By entering this password, the user is granted full access to the conguration settings and could
interrupt a live program.
BirdUI Layout
The BirdUI is organized into the following panels:
1. Dashboard
Overall view of important information such as the network connection type and video
stream format and resolution.
2. Network
General network settings such as DHCP IP Address details, DHCP timeout, DHCP Fallback IP Address, Network Name, designation of group access and NDI® specic network settings

Network
Network Details
NIC Medium Select
Select the desired network connection. Note that SFP+ is the default selection.
Conguration Method
You can congure the device to operate on the network with a dynamic (DHCP) IP Address or a xed Address. For
smaller networks DHCP networking is generally suitable, however larger networks with managed operations will
often determine each device needs to have a dedicated and static IP Address.
DHCP IP address
DHCP is set as the network conguration by default.
Static IP address
To enable a static IP address, change conguration method to static and ll in the details required in Address, Mask
and Gateway. Particular attention should be paid to the Address and Mask elds as incorrect information entered
will result in the device not being visible on the network.
DHCP Timeout, Fallback IP Address, Fallback Subnet Mask
You can set the timeout period during which the converter will look for a DHCP IP Address. After this period, the
camera will default to the designated fallback IP Address.
This can be useful if you use your camera in other network environments. For example, if a DHCP server is available
in your normal oce or studio application, the converter will use the DHCP supplied IP Address. If you then use
the camera in another application without a DHCP server, your device will always default to the known fallback IP
Address. Note: Do not set the fallback IP Address the same as the device IP Address. It is recommended that you
keep the default.
IP Address Recovery
In the event that the device is not visible on the network, the network has changed, or the static IP Address details
have been lost, reset the BirdDog back to its default settings by following the factory reset procedure.
BirdDog Name
You can name each converter with a memorable name that makes sense for each production. This name will
appear on any NDI® receiver when it looks for video over the network. The name must not include any special or
uppercase characters but can be any combination of ‘a-z, 0-9, and –‘.

NDI Network Settings
The OG4 operates with the latest NDI® Libraries. There are several options to congure its behaviour in an NDI®
network. Each conguration has its benets, however it is recommended to utilise the default TCP transmit method
unless you have reason to change.
Transmit / Receive Preferred Method
TCP
TCP is the default transmission method for NDI®. It operates well in local networks with predictable latency and
limited jitter. BirdDog recommends that TCP be used for typical applications, and using alternative transports only
for specic reasons.
UDP
UDP is recommended for networks where there is extended latency. The nature of UDP allows dropped packets
and doesn't establish handshaking dialogues to conrm each received packet – which can improve performance.
UDP can have some consequences if there are other issues on the network, such as jitter or packet loss, as lost
packets will not be resent.
R-UDP (Reliable UDP)
This protocol bridges the performance of TCP and UDP. Compared to TCP, R-UDP reduces overall network load
(allowing more NDI® streams) by not requiring every packet to be ‘acknowledged’ by every receiver. Built-in error
correction adds smoothness and reliability.
NDI Discovery
By default, NDI® utilizes mDNS (multicast Domain Name System) to create a zero conguration environment for
network discovery. The primary benets of using mDNS is that it requires little or no administration to set up.
Unless the network is specically congured to not allow mDNS, NDI® sources will be discovered.
The NDI® Discovery Service is designed to allow you to replace the automatic discovery with a server that operates
as an ecient centralized registry of NDI® sources resulting in much less bandwidth use. NDI® discovery server
also helps with location of devices that reside on dierent subnets. The NDI® Discovery Server is available as part
of the free NDI Tools in NDI version 5.5 (C:\Program Files\NDI\NDI 5 Tools\Discovery\NDI Discovery Service.exe).
1. If you are using a NDI® Discovery Server, click the ON button.
2. Enter the IP Address of your NDI® Discovery Server.
3. Click the APPLY button to save your changes.

Remote IP Address List
By default, NDI® devices are visible to each other only when they’re
on the same VLAN. If you want visibility or control of a device on a
dierent VLAN, you need to add it’s address manually as a Remote IP.
1. Click the CHOOSE FILE button to load your Remote IP Address
List in UTF-8 encoded string format.
2. Click the UPDATE button. Do not upload a blank list.
NDI Receive Groups
Set the NDI Receive Group. NDI® Groups allow you to restrict
communication to only devices that belong to the same NDI® Group.
NDI® Groups can be very useful in larger environments to control
visibility and access amongst various groups.
1. Click the CHOOSE FILE button to load your NDI Receive Group
List in UTF-8 encoded string format.
2. Click the UPDATE button. Do not upload a blank list.
Encode Groups
Enable and set the Encode NDI Group for each channel. NDI® groups allow you to restrict communication to only
devices that belong to the same NDI® group. NDI® Groups can be very useful in larger environments to control
visibility and access amongst various groups.

Bitrate Management
BirdDog devices allow you to set your target NDI®output bitrate. This allows you to select a compression ratio
that is more ecient (uses lower bandwidth) on your networking infrastructure or higher image quality for critical
footage. By setting Bitrate Management to NDI MANAGED, the BirdDog device will manage the target bitrate in
accordance with the NDI® standard. By selecting MANUAL you are able to manually select a target bitrate.
NDI Video Bandwidth
If you have selected a manual bitrate management, you may set your target NDI® output bitrate here. This allows
you to select a higher bitrate stream for a higher quality video if your network capacity allows. Select from 60 - 360
Mbps. Use the manual setting with caution, as higher bitrates may cause issues such as frame tearing with video
sources of high temporal complexity.
Chroma Subsampling
Set the desired level of chroma subsampling. To maintain performance when encoding 4K resolutions on multiple
channels, it is recommended to use the Chroma Subsampling option of 4:2:0.

Page 17
NDI Stream Name
When your BirdDog converter generates an NDI® stream, it can be identied via it’s name on any NDI®-capable
receiver. You are able to nominate the NDI® stream name here to give you a more descriptive name of the source
you are connecting to. This can be particularly useful in multi-channel devices or on networks where there are a
large amount of NDI® streams.
Video Format
This converter is capable of accepting many dierent video formats to encode to NDI®. For the most part it is
recommended to leave Video Format set to AUTO, you can manually override this setting and choose whatever
resolution your source device is set to. This can be useful if there is an issue in synchronising video input resolutions.
NDI Group Enable
This allows you to limit the visibility of the device to other devices that belong to the same NDI® Group. By default
this setting is DISABLED. When enabled the receiver device needs to also be set to the same identical group
name. Commonly this is done using the NDI Access Manager application provided by NewTek free of charge. NDI®
Groups can be very useful in larger environments to control visibility and access amongst various groups.
Encoder Screensaver
