INTRODUCTION
Welcome to Helix Broadcaster 100. This guide explains how to install and run
Helix Broadcaster with the embedded Helix Server. It shows you how to configure
inputs from the capture card or a network source and create encoded output
streams using the Helix Broadcaster 100 touch screen interface.
How this Guide Is Organized
Chapter 1: System Setup
You set up Helix Broadcaster by assigning it an IP address as described in this chapter, which
also explains how to access the browser interface.
Chapter 2: Inputs
This chapter walks you through the process of receiving input from a device such as a camera
or another server.
Chapter 3: Outputs
Using any input, you can create up to three outputs that you pass to Helix Server for client
streaming or forward to another server or encoder.
Chapter 4: Video and Audio Options
This chapter describes the audio and video encoding options that you define for any output.
Appendix A: Console Setup
This appendix explains how to use the console menu to set up the Helix Broadcaster IP
addresses along with other network settings.

CHAPTER
1
Chapter 1 : SYSTEM SETUP
This chapter describes the basic setup procedure for Helix Broadcaster. It describes
how to configure IP addresses or DHCP lookup. It also explains how to access the
browser-based interface, which you can use in addition to or instead of the Helix
Broadcaster 100 touch screen interface.
Setting up Helix Broadcaster
The back of the Helix Broadcaster machine provides the power input and a primary Ethernet
port (WAN port), which is labeled with a default IPv4 address. Plug the power cable into the
power input and connect the WAN port to your network using an Ethernet cable (not
provided).
Ethernet Ports on an Intel Board
Tip: The WAN port will be labeled with a default IP address. With an Intel board, the
port is on the right. On a Supermicro board, it is on the left.
Functional Connectors
Hardware connectors other than the Ethernet ports and the capture card inputs on the Helix
Broadcaster 100 front and back plates are not functional. This includes USB ports, microphone
and speaker jacks, and digital output ports such as HDMI.
Power Switch
Once the power and network cable are connected, press the power switch on the front of the
unit to start the machine.
Power Switch

Tip: Depress the power switch approximately five seconds to turn the unit off.
Press the power switch briefly or tap the screen if the screen times out.
Setting the WAN Address
The back of the Helix Broadcaster 100 lists the default IP address for the WAN port. If you
must change the WAN IP address or enable DHCP before placing the Helix Broadcaster
machine on your network, follow the procedures below.
Tip: If you can place the machine on your network without changing the
default IP address at first, you can use the machine immediately and log in to
the browser or SSH interface as described on page 5. You can then modify
network settings, such as setting the address for both the primary and
secondary Ethernet ports.
Network Setup Screen
Do the following to display the Network Setup screen where you can enable DHCP or set the
static IP address.
➤To display the network setup screen:
1. Tap System on the Appliance Manager menu.
System Category on Appliance Manager Screen
2. Tap Network on the System Setup menu that appears.
Network Category on System Setup Screen
3. The Network Setup screen appears. You can then configure DHCP or set a static address as
described next.
DHCP Lookup
If your network uses DHCP to assign IP addresses, set Helix Broadcaster to query the network
and receive an IP address.

➤To enable DHCP:
1. On the Network Setup screen, tap the DHCP radio button.
DCHP Setup
2. Tap OK.
3. Reboot the machine:
a. Close the System Setup screen.
b. Tap Services on the Appliance Manager menu.
c. Tap Reboot Now.
4. Navigate back to the Network Setup page.
5. The Static IP field will list the IP address assigned to the Helix Broadcaster machine.
Tip: To highlight the network settings, you can tap the Static radio button. Be
sure to tap DHCP again or cancel the changes to continue using DHCP.
Static IP Address
Follow this procedure to set a specific IP address for the Helix Broadcaster WAN port.
1. On the Network Setup screen (see page 3), tap the Static radio button.
Static IP Setup
2. In the Static IP field, press and hold the “-” and “+” buttons to set each decimal value for
the IPv4 address you want to assign to Helix Broadcaster.
3. Set the values for Mask, Gateway, and DNS as specified by your network administrator.
4. Tap OK.

5. Reboot the machine:
a. Close the System Setup screen.
b. Tap Services on the Appliance Manager menu.
c. Tap Reboot Now.
6. Navigate back to the Network Setup page and verify that the IP address has been set to the
correct value.
Helix Broadcaster Interfaces
Helix Broadcaster 100 provides three interfaces that allow you to perform various functions:
•touch screen interface
This document describes the Helix Broadcaster 100 touch screen interface, which allows
you to perform basic encoding tasks. Using this interface, you can receive two network
inputs and two capture card inputs. For each input, you can encode up to three outputs.
•browser interface
The browser interface (see page 7) gives you full access to Helix Broadcaster 100, providing
more encoding options than the touch screen. It allows you to configure the embedded
Helix Server as well as perform file-to-file encoding.
Note: Once Helix Broadcaster is available on your network, you can use the
browser interface rather than the touch screen to carry out all system functions.
•console menu
The console menu gives you access to Helix Broadcaster 100 configuration and network
functions. Once Helix Broadcaster is available on your network, you can use the console
menu through SSH as explained in Appendix A beginning on page 32.
Touch Screen Interface
When Helix Broadcaster starts up, it displays the Appliance Manager menu on its touch screen.
Appliance Manager Menu
System Functions and Services
The Appliance Manager icons give you access to the system functions.
System Set basic system features such as the WAN IP address.
Services Access system services such as rebooting the machine.
Stream Setup Receive inputs as described in Chapter 2 and encode outputs as described in Chapter 3.
