1Getting started
This manual provides one with all the information needed to install, configure and use the
Xtra.Emergency Button.
The Xtra.Emergency Button is a product that can be used to stop or to slow down go karts and does
not disconnect electrical circuits of the go karts. The Xtra.Emergency Button is a supportive product
that could result in less dangerous situations. The Xtra.Emergency Button is designed as supplement
to make karting safer but cannot replace safe track procedures.

1.2 Installation
Before installing the Xtra.Emergency Button, it is important to understand that the Xtra.Emergency
Button is not able to stop or slow down go karts which are out of range. Therefore it is necessary to
prevent any blind spots by using one or more Xtra.Black Boxes. The Xtra.Black Box is capable of
receiving the messages of the Xtra.Emergency Button and forward them across a wide range on the
track.
The Xtra.Emergency Button is a product that has to be activated manually. For this reason it is
important that the Xtra.Emergency button is easy to access and installed at a location without
obstacles.

1.2.2 Connecting
This chapter describes how to connect the Xtra.Emergency Button.
Figure 8 - Xtra.Emergency Button
1. Ethernet connector: Used to provide power to the Xtra.Emergency Button through power over
Ethernet and may also be used for Ethernet communication. The waterproof connector of the
supplied Ethernet cable must be connected to the Ethernet connector of the Xtra.Emergency
Button and the other end of the cable must be connected to the port labeled OUT on the power
over Ethernet injector.
Figure 9 - Power over Ethernet injector
The power over Ethernet injector features two ports labeled IN and OUT. The port labeled OUT should
be used to connect the power over Ethernet injector to the Xtra.Emergency Button using the supplied
Ethernet cable. The port labeled IN may be used to provide the Xtra.Emergency Button with access to
an Ethernet network by connecting the port to a network router or switch using an Ethernet cable.
For the power over Ethernet injector to function, it must be plugged into a wall
socket.
The side of the supplied Ethernet cable that connects to the power over Ethernet
injector as well as the power over Ethernet injector itself are NOT waterproof.
Make sure these are protected from water!

3.2.2.1 Change the LAN settings
In the LAN section, two modes can be selected: Dynamic IP (default) and Static IP. When the Static IP
mode is selected, the user must provide some network properties. After changing the LAN mode, the
Xtra.Emergency Button needs to be restarted for it to take effect. This can be done by temporarily
removing the power from the device or by using the restart button on the System Tools webpage.
Figure 14 - LAN section of the setup webpage
3.2.2.2 Enable or disable tracks
In the EMBU SPD Mode section, the user can indicate to which karting tracks the Xtra.Emergency
Button belongs using checkboxes. This is so that the product only responds to radio signals that are
intended for these tracks. By default, all tracks are enabled. If none of the tracks are enabled, track A
will be enabled automatically.
Figure 15 - Xtra.Network section of the setup webpage
The Static IP mode should only be selected by users with knowledge of the local
network. Entering incorrect network properties may result in loss of access to
the web interface and/or the Xtra.Emergency Button itself.
