Connect to T-RAX
T-RAX can be congured using its built-in web interface. This is accessible over your network,
or via the built-in Wi-Fi.
Ethernet defaults
IP mode: DHCP, T-RAX will request an IP address from your network. View the IP address by
pressing the < and > button on T-RAX until the Network screen is displayed.
Bonjour: Bonjour is enabled by default, and can be used to nd T-RAX without using the IP
address. If your web browser supports Bonjour, T-RAX will appear as a Webpage with the
default friendly name T-RAX xxxxx Administrative Console where xxxxx is the last 5 digits of the
controller card’s serial number.

Once you’ve connected a computer or tablet to the same
network as T-RAX, view the admin panel by opening a web
browser and either selecting the Bonjour friendly name or
navigating to the IP address.
The T-RAX admin page contains status information and conguration options for the T-RAX
system and all of the connected cards.

FIRST TIME USE
Installing T-RAX
1. Connect 100-240v A/C power to the power input (6) on T-RAX via the included IEC cable.
Connect a second cable if your device includes a redundant power supply (7).
2. Connect an Ethernet cable between the 10/100/1000 Ethernet port (x) and a network
switch.
3. Connect SD/HD-SDI video sources to any input BNCs corresponding to installed

Stream information
T-RAX encoder cards are congured to stream via RTSP by default. When an active video
signal is connected, you can preview the stream using a computer or mobile device.
Note: video streaming is only supported over the Ethernet interface.
Stream to a Computer:
Use an RTSP player (such as VLC) to open the following URL.
rtsp://ip.address:port/stream1
ip.address: T-RAX’s Ethernet IP address.
port: 255x, where x corresponds to the T-RAX card slot.
Configuration
T-RAX has a number of options available to help it t into
your existing IT and video workow requirements. This section
discusses some of the most commonly adjusted parameters,
separated into Network, Streaming, and Encoder sections.
Network
From the web UI, congure the T-RAX Ethernet interface and
other network options by opening Network > Conguration,
and the Wireless interface by opening Network > WiFi.
The network conguration page also shows statistics about the Ethernet interface, including
up time, the MAC address, IP address, and the amount of data sent and received. The
following conguration options are available.
• Protocol – Select between DHCP client and Static address. When set to DHCP, T-RAX will
request an IP address and all other network conguration from the network’s DHCP server.
When set to Static address, you will need to manually congure the IP address, subnet
mask, gateway, and DNS server to connect to the network.
• Hostname to send when requesting DHCP – Enter an alphanumeric host name, this is
used by T-RAX to identify itself when requesting a DHCP lease. This does not need to match
the System hostname, which is congured on the System > Conguration page. This value
can be left blank.
Streaming
T-RAX encoder cards are capable of encoding video and streaming it using a variety of
dierent protocols. Choose the Stream Mode best suited for your application. Find information
on two common stream modes below. View the current streaming conguration by navigating
to Cards > Conguration, and click the Edit button next to a listed card to modify the
conguration. All Streaming options are located under the card’s Stream tab.
RTP/RTSP
T-RAX encoder cards are congured to stream via RTSP by default. RTSP is used for local
streaming to computers and Teradek decoders. The URL for a standard RTSP stream is
rtsp://ip.address:port/stream1, where ip.address is T-RAX’s Ethernet IP address. Port is 255x,
where x corresponds to the T-RAX card slot.
Transport Stream
In transport stream mode, the encoder card sends
video via UDP or TCP to a specied unicast or
multicast address. The MPEG transport stream
protocol is used in many broadcast applications
and is also supported by many IPTV set top boxes.
To enable transport stream, select ‘MPEG Transport
Stream’ as the Stream Mode, choose your streaming
protocol (see below), enter your destination IP address
and port, and click ‘Apply.’
• Protocol: TCP is recommended when streaming
over the internet or a WAN. For streaming over
a local network, UDP can be used to avoid the
additional network overhead of TCP. On a local
network, use ‘UDP (Unicast)’ if streaming to a
single decoder, or ‘UDP (Multicast)’ when streaming
to multiple decoders over a multicast-capable network.
• Auto Start Push: If enabled, the encoder will push video to its destination as soon as the
codec starts. Video can be paused and resumed using controls on the Stream page.
Video Bitrate: Allows you to select dierent bitrates or manually enter your stream’s target
bitrate (in bits per second). Lower bitrates require less bandwidth and may allow for a more
stable stream. Higher bitrates oer better video quality, but require more network bandwidth.
See below for recommended video bitrates based on the resolution.
RESOLUTION RECOMMENDED MINIMUM BITRATE
1920x1080
1280x720
960x540
SD (480i/p, 576i/p)
480x270
360x240
Audio Bitrate: Similar to above video bitrate setting. Use this to adjust the audio bitrate, if
enabled.
Output Resolution: Adjust T-RAX encoder’s streaming resolution. If your network conditions
have bandwidth restrictions or if you are streaming to mobile devices or the Internet, you can
scale the encoder’s video to a smaller size to maintain video quality. You can also adjust the
video stream’s frame rate here.
Key Frame Interval: Adjusts amount of time between full picture refreshes. Increasing this
value allows for better video quality at a given bitrate. Decreasing the value may lower the
overall image quality, but will allow for quicker recovery of the stream if data is lost during
transmission. By default, the encoder generates one key frame every two seconds.
Title Text: Enter your desired title text here. Check ‘Show Title’ to display the title text on your
video stream. If the title text is enabled, you can also display the encoder’s system time by
checking ‘Show Time Code.’ The title text is also used as your channel name, and the default
name is ‘Channel 1.’

Encoder
In addition to conguring your stream type, T-RAX allows you to control various characteristics
of the network video stream. These include bitrate, frame rate, video scaling, and more. All of
these settings can be found under ‘Video Setup’ -> ‘Encoder Settings.’ Use this page to adjust
the video stream to best suit your streaming environment.
