INTRODUCTION
For over 80 years, Riddell has been the recognized leader in helmet technology and innovation. Founded
with the mission to make sports equipment safer, better, and easier to use, Riddell continues to address the
evolving protective equipment needs of the athlete. Today, Riddell equipment is seen on football fields from
coast-to-coast, protecting every level of player—from youth athletes to NFL professionals.
Our commitment to the Sideline Response System™ (SRS™) is a natural extension of our intimate
involvement with team sports and our core competence in player protection. SRS is an interconnected matrix
of advanced technologies that together define the next generation in head impact exposure monitoring.
Concussions and other MTBI’s are sometimes called “invisible injuries” because symptoms may not appear
for 24 hours (or later) after a head injury. The athlete may not immediately have impaired motor skills nor
be aware of the injury, making detection and evaluation extremely difficult for sideline personnel.
The Sideline Response System monitors and records head impact exposure during play and alerts sideline
personnel that an atypical exposure has occurred. It improves the efficiency and effectiveness of all sideline
staff, and it encourages the consistent application of appropriate practices by qualified personnel.
You must read this User Guide completely before set-up and use of the Sideline Response System. If you
need assistance with use of the system, please contact Riddell SRS Customer Support at [phone].

PRODUCT OVERVIEW
The Sideline Response System is composed of the following components:
1. MxEncoder (Figure 1): Installed in players’
helmets to record head impact data and
transmit to the Sideline.
Figure 1: Revo Speed MxEncoder installed in
Revo Speed helmet (Overliner removed for
clarity).
2. SRS Field Case (Figure 2): Holds all
required components of the SRS (excluding
MxEncoders and Battery Charger).

3. SRS Computer: Pre-loaded with all required
software to use the SRS.
4. Sideline Controller (Figure 3):

6. Alert System (Figure 5): Alerts sideline staff
of any player sustaining an impact above a
threshold. Users may select from several
pre-defined thresholds, or define their own.

7. SRS Software: Suite of custom software to
setup, manage, and use the SRS hardware
in the field.

MxEncoder
The MxEncoder, Figure 7, is the impact sensor and wireless radio worn
by the athlete. Each MxEncoder is installed in a player’s helmet and
contains six single-axis ±250g accelerometers that record head impacts
as they occur and transmit that information in near real-time to the
Sideline Controller. MxEncoders are designed to fit comfortably within
the helmet with no modifications needed, and to retain the NOCSAE
certification as installed.
A 3.6V rechargeable NiMH Battery Pack, Figure 8, is used in each
MxEncoder and typically holds a charge for one week during normal use.
IMPORTANT: Only SRS MxEncoder Battery Packs should be used to power
MxEncoders
The MxEncoder has an automatic On/Off switch that turns on once the helmet is
placed on the player’s head and shuts off when the helmet is removed. The switch
uses proximity based sensing that determines when there is a head in the helmet.
A hand may also be used to turn the switch on. The switch automatically turns off
the unit after it no longer senses the presence of a head in the helmet.
MxEncoders must be installed in the appropriate model/size helmet according to
the chart below.

SRS Field Case
The SRS Field Case, Figure 9, is a protective carrier designed to provide
convenient storage for all system components, protect electronics from
adverse weather conditions, and make the SRS easy to use on and off the
field.
The Field Case is configured with internal power outlets and data transfer
connections. Power is provided to the case via an external plug on the left
side of the case. External 120v AC power is required while collecting data
on the field.
The Field Case is water resistant and contains a ventilation system. This
means that the lid of the case can be closed while it is raining and still collect
data and transmit alerts.
Depending on the system purchased, the SRS Field Case is one of three
models: 900MHz only, WiFi only, or Dual Mode (900MHz & WiFi).
SRS Computer
The SRS Computer is a laptop computer that is configured for a specific SRS team to record all head
impact data and allow system setup and maintenance. The computer uses a Windows 7 operating
system.
Sideline Controller
The Sideline Controller, Figure 10, transmits and receives information to each
900MHz MxEncoder. The Sideline Controller relays this information to the SRS
Computer. The Sideline Controller can simultaneously communicate with up
to 100 MxEncoders up to 150 yards away. Power is supplied through a
waterproof USB connection on the outside of the Field Case. The Sideline
Controller is water resistant and can remain in operation during all weather
conditions. Available in 900MHz only and Dual Mode Field Case models.
Access Point
The Access Point, Figure 11, transmits and receives information to each WiFi
MxEncoder. The Access Point relays this information to the SRS Computer. The
Access Point can simultaneously communicate with up to 100 MxEncoders up to
150 yards away. Power is supplied through a waterproof USB connection on the
outside of the Field Case. The Access Point is water resistant and can remain in
operation during all weather conditions. Available in WiFi only and Dual Mode Field
Case models.

Alert System
The Alert System consists of two parts:
Alert Pager: This is carried by sideline staff and displays the player
number, impact magnitude, alert type and impact time for any impact
that is above a player’s customizable alert threshold. Multiple Alert
Pagers can be used with the same SRS. The Alert Pagers have a
communication range of 1/8th of a mile.
Alert Pager Transmitter: This is housed in the base of the Field Case and
transmits valuable alert information to all available Alert Pagers.

SRS Software
The SRS comes with two software applications, RedZone and HIT Analyzer. These software applications work
together to allow you to create sessions, manage roster lists, collect impact data, monitor system
performance, and analyze player and team impact data.
RedZone
Used off the field (web based)
Manage roster list and equipment
assignments
Manage sessions
View head impact exposure data for every
player
Create detailed summary Player Reports
HIT Analyzer
Used on the field
Collect head impact data in real time from all
active players
Make roster and session adjustments as
needed while on the field
Provides system functionality status and
session summary statistics
Battery Charger
The Battery Charger is capable of recharging up to 40 MxEncoder battery packs simultaneously. Typical
charging time is 4 -6 hours for a drained battery. The charger has a built in protection circuit that
automatically shuts off the charging cycle once a battery has been fully charged to prevent damage. There
are two ventilation fans that turn on when the charger is powered on to prevent the charger from over-
heating, and the charger also has an over-temperature sensor to shut off the charging cycle if a battery is
damaged. The charger should only be used indoors with the lid open to prevent from over-heating. The
charger is only to be used with corresponding Riddell SRS NiMH battery packs (P/N R64207).

NOTE: See the Equipment Guide for help on MxEncoder installation and the MxEncoder/Helmet
compatibility chart.
2. Install charged battery pack into each MxEncoder.
3. Install the overliner if the helmet is supplied with one.
4. Edit/verify that all player profiles have the correct MxEncoder serial number and helmet model/size.
On the field
1. Setup Field Case in a central location of the sideline and away from large metal objects.
2. Plug in power cable to side of Field Case and then into power outlet/extension cord.
3. Attach Sideline Controller Mast to side of Field Case.
4. Screw Sideline Controller onto Mast.
5. Attach Antenna to Sideline Controller connector.
