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.
