1. INTRODUCTION
The Audience Interaction wireless system allows you to implement audience interaction
technology for meetings, delegate voting, strategic planning, training, customer surveys, focus
groups, games shows and more. AI system hardware, Handsets and Base Station(s), allow
audience members to register their responses with your host computer running third-party
audience response software.
An AI system is Fleetwood
compatible at the interface of
the AI system with the host
computer. Although AI
Handsets communicate with
an AI Base Station using a
proprietary protocol, the AI
system communicates with
the host computer using the
Fleetwood Standard Reply®
protocol. Therefore, your thirdparty audience response
software can be configured for
an AI system as it would be
for Fleetwood hardware.
This manual covers the
installation and operation of an
AI system including the

Fig. 11. Typical System Configuration
During the voting of an audience response question, the following sequence occurs:
•
•
•
•
•
•
System operator “opens the vote” with the audience response software on the host
computer
Audience response software generates a question display that is projected by the video
projector
Audience members respond to the question by pressing keys on their Handsets
Handsets register their votes with the supporting Base Station
System operator “closes the vote” with the audience response software
Audience response software polls the Base Station and generates a results display that
is projected to the audience
AI System Manual (Jan-04)
Installation and Operation
Handsets transmit audience votes using radio frequency (RF) signals to the supporting Base
Station. Handsets communicate with their supporting Base Station on one of 25 available
channels in the 902-928 MHz frequency range. Base Stations accumulate votes from
associated Handsets and pass them to the host computer via a USB cable.
Each Handset is assigned an identification (ID) number during manufacture. The supporting
Base Station identifies each Handset by its ID number. A total of 250 Handsets can be
managed by a given Base Station (ID 1 through ID 250).
Although the starter system shown above illustrates a single Base Station configuration, several
Base Stations can be used to expand the number of Handsets. Each Base Station requires a
USB port and operates on its own channel.
Note: When multiple Base Stations are used, they should be separated at least
18 inches to avoid interference. Base Stations should not be located near
metallic objects. When a Base Station is placed adjacent to the host computer,
place it on top of the computer case.

refer to the System Operation section below.
6. SYSTEM OPERATION
The sections below describe the configuration of typical audience response software to
interface with an AI system. For additional information on configuring your audience response
software, refer to your user documentation. The characteristics of normal AI system operation
are also discussed. For information on AI system troubleshooting, refer to the Troubleshooting
section.
6.1 Audience Response Software
Before you can collect and display votes with the AI hardware, you must install and configure
your audience response software.
Note: The AI system is software-compatible with the communication protocol
used by Fleetwood Standard Reply® keypads. When you configure your
audience response software, select the "Fleetwood" or "Fleetwood Standard"
option as appropriate.
AI System Manual (Jan-04)
16
Installation and Operation
Configuring audience response software usually involves the following:
•
•
•
Selecting the type of keypad hardware being used — “Fleetwood” or
“Fleetwood Standard”
Selecting the COM port to which the base station is attached — may be
detected automatically
Identifying the number of keypads supported by the base station
Note: In general, audience response software packages support Fleetwoodcompatible Handsets in groups of 50. Therefore, you should configure your
package for one of the following groups depending on the number of Handsets
purchased:
Beginning
Ending
Handset
Handset
Number
Number
50
100
150
200
250
Thus, if you purchased 125 Handsets (ID 1 through 125), you would configure
your audience response software for a Handset grouping 1 through 150.
AI System Manual (Jan-04)
17
Installation and Operation
If your audience response software does not automatically detect the COM port to which the
Base Station is attached, you can identify the USB port number by performing the following

Installation and Operation
7. TROUBLESHOOTING
This section focuses on system troubleshooting — procedures for identifying and repairing
problem components.
At this point, you should have accomplished the following:
•
•
•
•
•
•
Powered the host computer
Cabled the AI system
Installed AI USB drivers
Installed and launched the audience response software
Configured the audience response software for an appropriate number of “Fleetwood” or
“Fleetwood Standard” hardware
Conducted test votes
Successful system troubleshooting is based on several factors including:
•
•
•
A systematic procedure
Identification of problem scope
Knowledge of component operation
7.1 Basic Methodology
It is important to approach troubleshooting in a systematic way, working on one component at a
time. Obviously, if you change two components before retesting, you cannot be sure which
change produced the solution. As soon as you check a component, perform a test vote to
confirm the resolution or continuation of the problem.
Various diagnostic aids are built into system components including LEDs on the Base Station.

7.3 Identifying Problem Scope
The scope of a problem is an important factor in troubleshooting. For example, if a single
Handset is not functioning, your troubleshooting will focus at the Handset level. If an entire
channel is not functioning, the focus of your troubleshooting will include the supporting Base
Station, USB cable, USB port and audience response software configuration. If no votes are
received during a test vote or the pattern of votes is atypical, the host computer and audience
response software become the focus of your troubleshooting.
The sections below contain checklists for various types of problems. Each checklist describes a
problem and includes various things to check and things to try.
Problem:
Check:
Try:
Problem description
Things to check?
Things to try
When a check reveals the source of the problem, the solution is generally self-evident. When
all checks fail to solve the problem, generally one of the listed things to try will resolve the
malfunction.
7.3.1 Individual Handset Problems
When a Handset fails to register a vote, perform the following:
Problem:
Check:
Check:
Try:
Handset does not register a vote
Batteries OK?
Distance to supporting Base Station within reliable transmission range?
Replace the Handset
Generally, replacing the Handset’s batteries will resolve most individual Handset problems.

22
Installation and Operation
7.3.2 Communication Channel Problems
If you are using multiple Base Stations, it is good operating practice to install Handsets so that a
given channel serves a given section of the meeting room. Using this arrangement, problems
with a given section equate to problems with a given channel.
If all Handsets in a given section do not respond, the problem may relate to one or more of the
following:
•
•
•
•
The supporting Base Station
The connecting USB cable
The audience response software configuration
The USB port on the host computer
When Handsets on a given channel fail to register votes, perform the following:
Problem:

Installation and Operation
7.3.3 Problem Areas in the Room
If a small number of adjacent Handsets do not respond, the problem may be related to their
location. The Handsets may be located beyond the reliable transmission range, or there may
be some form of radio frequency (RF) interference in that area of the room.
Note: To date, interference from other RF sources (such as wireless
microphones or video equipment) has not been a problem with AI system
hardware. Although rare, large metallic surfaces that may be concealed in walls
or partitions can present problems for RF signals.
This problem can also result from errors in the configuration of the audience response software.
For example, when the audience response software is configured for Handset
ID 1 through 50, but Handsets 1 through 75 are present.
When several adjacent Handsets on a given channel fail to register votes, perform the following:
Problem:
Check:
Check:
Check:
Check:
Try:
A portion of a section does not register votes
Distance to Base Station within reliable transmission range?
Audience response software configured properly?
Base Stations separated at least 18 inches?
Base Station near metallic objects?
Replace Handset(s)
7.3.4 Room-Level Problems
When an entire meeting room does not report any votes or the voting pattern is atypical, the
host computer and audience response software become the focus of the troubleshooting
activities. An atypical voting pattern usually occurs when the audience response software is
configured for fewer Handsets than actually installed in the meeting room.
In a multiple Base Station configuration where an entire meeting room fails to register votes,
perform the following:
Problem:
Check:
Check:
Try:
The entire room does not register votes
Audience response software configured properly?
Host computer cabled properly?
Boot the host computer
Note: For room-level problems with a single Base Station configuration, refer to
the communication channel problem checklist.

Installation and Operation
7.4 Handset Repair
AI Handsets are rugged, highly reliable and should require little if any maintenance other than
periodic battery replacement. If the suggestions in the Troubleshooting sections above do not
resolve a malfunction, it may be worthwhile to open the Handset case. Most of the Handset
components are permanently installed and cannot be changed in the field. Although unlikely,
extremely rough handling might dislodge the batteries, the keypad connector or jumper.
Note: When a Handset does not function properly, the cause is usually batteryrelated — either depleted or slightly dislodged batteries.
Opening the Case
To inspect Handset circuitry, open the case by performing the
following steps:
Turn the Handset over and slide the battery
compartment cover off.
2.
Remove the AA batteries.
3.
Remove the two screws joining the top and
bottom of the case.
Important: A discharge of static electricity from a
finger or other conductor may damage electronic
circuitry. In general, avoid touching pins, leads or
circuitry. Before handling any of the internal
components, be sure that you have discharged static
electricity by briefly touching a grounded metal
object.

Handset circuitry is mounted on a printed
circuit board. The circuit board is mounted
with four circuit board retainers. Make sure
the circuit board is firmly in place — gently
bend the circuit board retainers if necessary.
Check that the jumper shown is in place.
If the jumper has become dislodged,
carefully reseat it.
Check that the keypad ribbon cable is
securely joined to the keypad connector.
Assembling the Case
To assemble the Handset case, reverse the opening
procedure — join the top and bottom of the Handset,
make sure the battery wires are routed behind the
battery clips, install the case screws, install the
batteries and replace the battery compartment cover.
Note: When you install batteries in a
properly functioning Handset, you should
hear a short series of tones.

AI Base Stations are highly reliable and should require little if any maintenance. If the
suggestions in the Troubleshooting sections above do not resolve a malfunction, it may be
worthwhile to open the Base Station case. Most of the Base Station’s components are
permanently installed and cannot be changed in the field. Although unlikely, extremely rough
handling may affect internal jumper settings.
Opening the Case
Important: Disconnect all cabling from the Base Station before opening the case.
Do not connect any cabling to the Base Station until the case is closed.
To inspect Base Station circuitry and jumper settings, open the case by performing the following
steps:
1.
From the bottom of the Base Station, remove the four screws securing the cover.
2.
Carefully lift the cover and remove the two end pieces if they are loose.
Important: A discharge of static electricity from a finger or other conductor may
damage electronic circuitry. In general, avoid touching pins, leads or circuitry.
Before handling any of the internal components, be sure that you have
discharged static electricity by briefly touching a grounded metal object.

Installation and Operation
Diagnostic Checks
Base Station circuitry is mounted on two printed circuit boards — a motherboard (MB)
and a daughterboard (DB) suspended above. Each circuit board is mounted with four
screws.

Check the three jumper settings shown above — two on the motherboard and one on
the daughterboard. If any of the jumpers have become dislodged, carefully reseat
them.
Assembling the Case
To assemble the case, reverse the opening procedure — replace the end pieces, cover and
case screws.
All Diagnostic Efforts Fail
If none of the troubleshooting and repair steps overcome the malfunction, replace the Base
Station with a spare (operating on the same channel) if available, label the defective unit with a
description of the problem and contact Audience Interaction.
