Welcome to the Future
What is NDI®?
Your new camera has been designed to support the cutting edge NDI® video transmission standard.
NDI® (Network Device Interface) is a high-quality, low-latency, frame-accurate standard that enables compatible
devices to communicate, and deliver and receive high denition 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 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 or HDMI signals can easily be converted to an NDI®
stream and piped where required on your network and converted back only at the necessary endpoints.
BirdDog has been on the NDI® journey since the very beginning, and your camera 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 Converter
Thanks for purchasing your BirdDog 4K Converter. Please take some time to read this document to allow you to
get the most out of your purchase and familiarize yourself with the features available in the unit.
Physical Connectors
Powering Your Converter
This converter is equipped with a sophisticated system allowing power from various sources:
PoE+ (Power over Ethernet)
PoE+ is a convenient way to power this converter as it allows both data and power to be sent through the same
standard Ethernet cable. To take advantage of PoE+, the network switch that the converter is directly plugged into
must support PoE+(802.11at).
Dierent network switches are capable of providing diering amounts of total power to all connected devices. This
FLEX 4K converter uses approximately 14 watts in PoE+ mode to operate on its own, and up to 30w when powering
additional equipment.
DC In
Located at the side of the 4K converter is a DC connection port. This power input socket is capable of accepting
12v DC power.
DC Out
Located at the side of the FLEX 4K converter is a DC Out connection port. This power outlet socket is capable of
delivering 12v DC power at up to 15w to power external equipment. Please note that if your external equipment
draws more than 15w the FLEX 4K unit will power o automatically.
NP-Style Battery Plate (4K BACKPACK Only)
The BirdDog FLEX 4K BACKPACK features a NP-style battery plate that allows you to mount the BirdDog FLEX
BACKPACK to another piece of equipment. The NP-style plate is designed to work with most equipment but may
not be possible to connect to all devices owing to physical constraints. Please note the NP-style DV output voltage
is 12v DC.

6
IMPORTANT NOTE WHEN POWERING EXTERNAL DEVICES
BirdDog FLEX 4K and FLEX 4K Backpack deliver 12v DC outputs which can be used for various purposes from
powering cameras to screens to external recorders. No warranty is given for the use of this feature with regards
to the suitability of your third-party equipment. It is advised that you should carefully check the user guide of
the equipment you wish to power to ensure it is capable of accepting 12v DC input and if there are any warranty
implications for using 3rd party power sources.
Thermal Management
This product has been engineered to be actively cooled. In order to achieve best thermal performance, the fan
assembly has been carefully designed to provide optimum cooling while remaining extremely quiet. It is normal
for warm air to pass through the vent voutlets. The main processor is capable of operating up to 100º C / 212º F.
Operating Your Converter
Boot Up
When FLEX detects a power input, the Halo Tally light will illuminate orange and the network activity indicator will
begin to ash indicating that the device's detection of the computer network. After approx. 20 seconds, the Halo
Tally will ash Red and then Green, indicating the unit is completely booted and ready for operation.
Web Conguration Panel
In this release, the web conguration panel (Web UI) allows you to alter key settings of your converter, specically
A/V settings, and video frame rates, restarting the video processing engine, changing networking parameters and
applying rmware updates.
Access via a Web Browser (URL)
To access the web conguration panel please point your computer web browser to: http://birddog-xxxxx.local/
“xxxxx” is the serial number of the converter, the serial number is printed on the box and on the main unit. Note the
web address is case sensitive and all lower case. Your computer will need to have ‘Bonjour’ services loaded in order
to access the unit as described above. Apple devices come pre-installed with Bonjour, while Windows devices need
a small plugin available here.
Access via IP Address
Your converter is congured to automatically receive a network IP address from the computer network via DHCP
(Dynamic Host Conguration Protocol). Most corporate, education and home networks have a DHCP server present
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 BirdDog Central Lite available from here.

7
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 conguration panel on a network which is congured to a dierent subnet, change your
computers IP address to match the BirdDog unit’s IP address range. Once you gain access to the BirdDog web
conguration panel 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 web conguration panel you will need to log in to change any settings.
Default Password
The web conguration panel is secured by a user-selectable password. The default password is:
birddog (one word, lower case).
To change the password, simply log in 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), since this password grants full access to the conguration settings and could interrupt a live
program.
Dashboard
The Dashboard summarizes the
important settings for the converter
in one convenient location. You can
also reboot the device or restart the
video processing engine.
Reboot Device
Click this button to reboot the unit
after changing key network settings
or the BirdDog name.
Restart Video
Click this button to restart the NDI®
stream. This may be necessary after
changing key image settings e.g.,
resolution.

Network
Most computer networks
provide for both automatic
and manual conguration of
network devices and FLEX can
accommodate both.
Conguration Method
Here you can set the network
conguration to either DHCP
(default) or Static. DHCP
simplies the management of
IP addresses on networks. No
two hosts can have the same
IP address, so assigning them
manually can potentially lead
to errors. If your network is set
up for DHCP, this is generally
the best conguration to
choose.
If you do choose to go with a Static IP address, you’ll need to add the IP Address, Subnet Mask and Gateway
Address information according to the requirements of your network.
DHCP Timeout, Fallback IP address, Fallback Subnet Mask
You can set the timeout period during which FLEX 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 oce or studio application, FLEX 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 to keep the default
fallback IP address.
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 give your device a meaningful name to make identication easier when viewing NDI® sources on a receiver
such as a TriCaster, vMix or Studio Monitor. Be sure to make the name unique, as no two devices on the network
should have the same name. The name can be any combination of a-z, 0-9, and –.
After renaming your device, navigate back to the System menu and click the REBOOT button. The camera will re-
initialize and you’ll be good to go.

9
PTZ
BirdDog FLEX 4K IN and FLEX 4K BACKPACK can control external PTZ cameras from RS-232 serial port using the
Sony VISCA protocol.
The PTZ Control tab controls allow you to save and recall 9 camera presets. Select the Settings tab to set your
cameras VISCA address and Baud Rate accordingly. By default, these settings are:
VISCA ADDRESS: 1
VISCA BAUD RATE: 9600
Once these settings are correct you can control your external PTZ camera within any PTZ-aware NDI control
application as if it was a native NDI PTZ camera.

10
System
Password Settings
The BirdUI is secured by a user-selectable password. To make changes to any settings, you'll need to log in.
The default password is birddog (one word, lower case). It is recommended that the default password be changed,
since the BirdUI grants full access to the camera conguration settings.
You can change the password in the Password Settings tab.
1. Enter the current password.
2. Enter the new password. It is recommended that you change this password to prevent unauthorized changes
in a network environment where PTZ Keyboard is shared with other users (e.g. not private). Conrm the new
password and click the APPLY button.
System Update
We are always adding new features and improving the performance of our products, so installing the latest rmware
will provide you with the best user experience.
To upgrade the rmware, download the rmware and follow the Firmware Upgrade Instructions located in the
download folder.

11
Conguration Update
Remote IP 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 dierent VLAN, you can add it’s address manually as a Remote IP. You can upload and
download Remote IP Lists for sharing with other cameras. To upload a list:
1. Click the CHOOSE FILE button to load your Remote IP List in UTF-8 encoded string format.
2. Click the UPDATE button. Do not upload a blank list.
NDI Group List
Set the NDI® Group list. NDI® groups allow you to restrict communication to only devices that belong to the
same NDI® Group. NDI® Groups can be very useful to control visibility and access in larger environments. You
can upload and download Group lists for sharing with other cameras. Groups also need setting up in NDI Access
Manager, available in NDI Tools.
To upload a list:
1. Click the CHOOSE FILE button to load your NDI® Group List in UTF-8 encoded string format.
2. Click the UPDATE button. Do not upload a blank list.

Network Settings
Preferred Transmit Method
TCP
TCP is the default method of
transmission for NDI®. It operates
well within local networks with
predictable latency and limited jitter.
BirdDog recommends that TCP be
used for typical applications, with
alternative transports used only for
specic reasons.
UDP
UDP is recommended for networks
where there is extended latency. The
nature of UDP means that it does not
receive conrmation of each packet
being received successfully – vastly
improving performance on busy
networks. Using UDP can have some
consequences if there are other
issues on the network such as jitter
or lost packets as it will not inherently
re-sent a lost packet.
Multicast
Multicast is especially useful for use-cases that require a single source to be received on multiple receivers
simultaneously. Utilizing Multicast ooads the distribution of the NDI® A/V packets from the BirdDog device
to the network infrastructure. You should take care to ensure your network is specically congured to support
Multicast as using it on an ill-prepared network can create unintended network problems.
MultiTCP
MultiTCP is a new NDI transport method that allows users to send NDI® video over poor network topography such
as WAN (Wide Area Networks) without experiencing packet loss and lost frames. Historically, UDP transport was
the only option to send NDI video over a WAN, allowing the NDI® video to travel without dropping frames but
resulted in dropped packets being missed which could cause unstable video. UDP also places more performance
demands on devices sending and receiving the signal.
MultiTCP employs a new method of sending TCP packets whereby it opens a mass of TCP connections over
the WAN and uses them in a ‘round robin’ manner, this allows each individual TCP connection enough time to
acknowledge the receiving packet, conrm nothing is lost and prepare for the next one before it’s sent the next
TCP packet in the round robin. This is similar to a RAID setup in traditional storage.
NDI Discovery
If you choose to use a NDI® discovery server, you can congure it in this tab. By default, NDI® utilizes mDNS
(multicast Domain Name System) to create the zero conguration environment for discovery. Unless the network
is specically congured to not allow mDNS, NDI® sources will be discovered.
The NDI® discovery service is designed to replace the automatic discovery NDI® uses with a server that operates
as an ecient centralized registry of NDI® sources that requires much less bandwidth. NDI® discovery server also
helps with location of devices that reside on dierent subnets. The NDI® Discovery Server is available in the NDI 5.5
version of the free NDI Tools (C:\Program Files\NDI\NDI 5 Tools\Discovery\ NDI Discovery Service.exe).
1. If you are using an 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.

13
AV
Device Settings
Audio Gain
Controls for adjusting the audio gain.
Encode Settings
Video Input Format
This converter is capable of accepting
many dierent video formats to encode to
NDI®. For the most part it is recommended
to leave Video Input 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.
Colour Space
BirdDog FLEX has built in colour space
conversion - some HDMI computer
sources provide video in RGB or YUV
colour space while others provide the
source as YVU colour space, notably
Apple Mac machines. If you experience
inverted colours on your computer-based
input, swap YUV for YVU colour space.
Chroma Subsampling
This BirdDog converter is capable of operating in two Chroma Subsample modes, 4:2:2 and 4:2:0. According to the
NDI specication, when you are operating in HD video resolutions the chroma subsampling should be set to 4:2:2
and in 4K is should be set to 4:2:0.
The BirdDog 4K converter line allows you to override these recommendations depending on your own needs. This
can result in greater representation of colours in your image, or less overall video compression. Generally speaking,
for video-sourced material in 4K it is recommended to use 4:2:0, but for computer generated graphics such as
gaming and presentations your chroma subsampling should be set to 4:2:2.

14
Bitrate Management
Birddog Devices allow you to set your target NDI® output bitrate. This allows you to select a level of compression
that is more ecient on your networking infrastructure (lower bandwidth) or higher image quality for critical
footage. The scale allows you to select anywhere from 60 Mbps to 360 Mbps.
By setting Bitrate Management to NDI MANAGED, FLEX will manage the target bitrate in accordance with the
NDI® standard. By selecting MANUAL, you are able to manually select a target bitrate.
NDI Output 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 60Mbps
to 360 Mbps.
NDI Audio
Select MAIN to enable NDI® audio only and ANALOG to enable audio in from the audio input. Select MUTE to
disable the NDI® audio.
Onboard Tally
Select whether the device Tally light is On or O, and click Video Mode if you wish the decode source Tally
information to be passed through.
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.
NDI Stream Name
When your BirdDog converter generates an NDI® stream, it can be identied 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.
Encode Screensaver
Assign a captured frame, black frame, or BirdDog logo as a screensaver.
Capture Screensaver Frame
Click the Capture button to capture the current frame for use as a screensaver.
Failover Source
If the generated NDI® stream is interrupted for any reason the receiver can automatically switch to a nominated
alternative NDI® stream. This is particularly useful for live ‘on air’ productions where there can be no risk of still
frames or black being broadcast should any source no longer be available. Select an available NDI® source for the
failover function from the Available NDI® Sources dropdown list. You can update this list by clicking the Refresh
button.

15
Factory Resetting Your Unit
If you have lost network settings or cannot nd FLEX on the network, you can perform a network factory reset.
Simply depress the reset button located next to the RS-232 port for 5 seconds until the Halo Tally ashes red. The
unit will be accessible as per factory settings, approximately 10 seconds later.
Receiving NDI Streams
There are many applications that support receiving the NDI® signal that the unit produces. Each application will
vary slightly on how you choose your source.
NewTek Studio Monitor
NDI® Tools is a free suite of applications designed to introduce you to the world of IP video and is available here.
The included Studio Monitor application allows you to monitor many NDI® sources on a standard Windows computer.
Once Studio Monitor is launched, right click anywhere in the interface and select FLEX from the dropdown list.
Once connected to FLEX, a conguration gear icon is displayed on the bottom right-hand side of the video display
providing shortcut access the WebUI.
NewTek TriCaster Series
NewTek TriCaster series devices allow several NDI® sources to be received simultaneously, the number of
simultaneous connections depending on what model TriCaster you have.
To select the FLEX as a source on your TriCaster, click on the conguration gear icon below your desired source
location. From the displayed Input Setting dialog, select your camera source from the dropdown list.
Once connected to FLEX, a conguration gear icon displays next to the source dropdown window that provides
shortcut access the FLEX WebUI.
