Warnings
The following warnings indicate the possibility of injury to the patient or the operator.
•
1–4
Be aware of signal interference, which can occur from external sources. Electronic
signals are required for the Alice 5 to function. Even though the system contains methods
and techniques that can provide protection from external sources of interference, you
should operate the system as follows:
–
Do not plug sensor lead wires into electrical outlets. Lead wire contact with electrical
outlets presents a serious shock hazard.
–
Place the system components on a sturdy and level surface. Do not place the base
station on carpeting.
–
Do not use the Alice 5 system within three feet of oxygen tanks or oxygen tents.
–
Do not operate the Alice 5 system in any explosive situation where flammable or

–
Do not connect telephone equipment to the auxiliary inputs.
•
If a patient has a cardiac pacemaker, consult with the patient’s physician prior to performing the study.
•
The Alice 5 device and its accessories are not protected against the effect of cardiac
defibrillation. Remove all patient leads (applied parts) before performing cardiac defibrillation.
•
Do not use the Alice 5 system in a Magnetic Resonance Imaging (MRI) environment or
in close proximity to a high emissions source.
•
Do not touch the base station and the patient simultaneously, as this may create an
electrical shock hazard.
•
Periodically inspect the electrical cords, cables, and the power supply device for damage
or signs of wear. Discard and replace any damaged parts before using.
Alice® 5 Setup and User’s Guide
•
Make sure that any wires attached to the patient are routed to reduce the likelihood of
strangulation.
•
Pins of connectors identified with the ESD warning symbol should not be touched.
Connections should not be made to these connectors unless ESD precautionary procedures are used. Precautionary procedures include methods to prevent buildup of electrostatic discharge (e.g., air conditioning, humidification, conductive floor coverings, and
non-synthetic clothing), discharging one’s body to the frame of the equipment or system
or to earth or a large metal object, and bonding oneself by means of a wrist strap to the
equipment or system, or to earth.
•
The conductive parts of electrodes and associated connectors, including the neutral
electrode, should not contact other conductive parts, including earth.
•
Do not use during high frequency surgical procedures or electrosurgery.
1.2.2
Cautions
The following cautions indicate the possibility of damage to the device.
•
For all equipment used with the Alice 5 system, follow all of the manufacturer’s recommendations and instructions. Be sure to read, understand, and follow the instructions in
this manual and others that come with the system and its components. If you don’t have a
manual, ask the equipment distributor or manufacturer for one.
•
Operation of the Alice system may be adversely affected by:
–
electromagnetic fields exceeding the level of 10 V/m in the test conditions of EN
60601-1-2
–
the operation of high frequency (diathermy) equipment
–
defibrillators, or short wave therapy equipment
–
radiation (e.g., x-ray, CT)
–
magnetic fields (e.g., MRI)
•
Synthetic fabric from draperies or rugs can also cause interference due to static electricity. Touching an inanimate object (e.g., wall, crib) before handling the patient or the
system often prevents static build-up problems.
•
Strong transmitter signals from TV, radio, airport, police, fire, and ambulance stations
could be received and interpreted as heart and/or breath signals. If you are located less
than one mile from any of these sources, ask Respironics Customer Service to assist you
in determining whether your system will operate properly.
•
Do not soak or immerse the base station or headbox in any liquid.
•
Never use an extension cord with the Alice 5 system. Always operate the device using a
properly grounded AC power outlet. If you are unsure whether a power outlet is properly
grounded, contact an electrician for assistance.

1.3 Intended Use
The Alice 5 system is a single-patient use, polysomnography system that is intended to record,
display, and print physiological information for clinicians or physicians. These parameters are
presented graphically on a computer screen for diagnostic review, similar in application to the
use of a traditional paper-based polygraph recorder. The device will be used in hospitals, institutions, sleep center or clinics, or other test environments where adults or infant patients require the
documentation of various sleep or other physiological disorders.
This device does not provide alarms and is not intended for use as an automated apnea monitor. It
is not for continuous monitoring.
The Alice 5 equipment collects the data from sensors placed on a patient and delivers the data to
a computer running the Sleepware application. The Alice Sleepware application is a Windowsbased software program designed to monitor, display, process, and download polysomnographic
data recorded with the Alice 5 equipment.
Note:
1–6
For information about using Microsoft Windows, refer to your Microsoft documentation. For more information about Alice Sleepware, refer to the Alice Sleepware User’s
Guide.
Alice® 5 Setup and User’s Guide
1.4 Hardware Component Overview
The Alice 5 equipment consists of the base station, headbox, polysomnographic sensors, and
auxiliary input devices.
The base station and headbox record, amplify, filter, and digitize various physiologic inputs. It
may collect up to 55 channels of data. The base station stores the data locally on an internal hard
disk until it is sent over a wired or wireless ethernet connection to a computer running the Alice
Sleepware application. Sleepware can display live or pre-recorded data in a resolution consistent
with the computer hardware specifications. Sound and video of the patient are available, and an
intercom feature allows you to communicate with the patient remotely.
The base station can also interface directly with several auxiliary input devices (e.g., EtCO2
monitors, etc.).
The two main components of your Alice 5 system are the base station and headbox. You can add
additional hardware components, such as video cameras, if needed. See Chapter 2 for information on how to set up video cameras. For information on additional Alice 5 accessories, refer to
the Respironics Diagnostic Accessory Guide.
1.4.1
Data Flow through the Alice 5 Components
The flow of the data through the Alice 5 system is as follows: From the patient, the sensors pick
up physiologic events. Sensor cables carry the signal to the Alice 5 headbox or to an auxiliary
device.
If the data then gets carried to the Alice 5 base station via the headbox, the signal is amplified
and treated before being transformed from analog to digital format. If the signal is sent to the
base station via an auxiliary input, it is not amplified by the base station because it was already
amplified and conditioned in the auxiliary unit.
The signals are digitized and stored in the base station. If configured, they are then sent from the
base station to the computer running the Alice Sleepware diagnostic application.
Figure 1–2 illustrates the flow of data during an Alice 5 acquisition.

type is assigned when a channel’s data is most useful to the
clinician when displayed as a graph (waveform) rather than a
number, and the data points of the curve are not clinically useful.
In other words, the curve, not its data points, are important.
Grapho-Numeric Display Type
One of three display types for generic channels. A grapho-numeric
display type is assigned when a channel’s data is most useful to the
clinician when displayed as a graph (waveform) and the data points
are also meaningful.
Headbox
A bedside remote amplifier that is part of the Alice system and is
used to collect physiologic data from sensors placed on the
patient’s body.

MAC Address
Media Access Control address. This is a unique hardware address
that identifies a device on a network. It is assigned by the manufacturer and cannot be changed. This address can usually be found on
the device packaging.
Montage
A montage (as distinguished from an acquisition configuration) is a
way to display re-referenced EEG and EOG data during or after an
acquisition. Each acquired EEG channel measures the difference in
electrical potential between a given (active) electrode and a
reference. The montage tool recombines EEG/EOG data in order to
display the difference in potential between any two electrodes.
Numeric Display Type
One of the three display types for generic channels. A numeric
display type is assigned when the data is most useful to the
clinician when displayed as a number, rather than a waveform.
OSA
Obstructive Sleep Apnea – A temporary cessation of airflow
without an accompanying cessation of respiratory effort.
pH
A measure of the acidity or alkalinity of a fluid. In sleep, this
generally refers to a measure of the acidity of fluid in the esophagus, detected by an esophageal pH probe.

Alice® 5 Setup and User’s Guide
CHAPTER
Alice 5 Equipment Setup
This chapter describes how to connect the hardware components included with the Alice 5
system. It contains graphics illustrating the connections as well as detailed step-by-step instructions.
There are several possible ways to set up your Alice 5 system:
•
Wired point-to-point setup, where wired devices communicate directly with each other
(e.g., base station to computer).
•
Wired network setup, where a switch is used to connect multiple devices to a Local
Area Network (LAN).
•
Wireless ad-hoc setup, a wireless networking framework in which devices communicate
directly with each other, without the use of an access point.
•
Wireless Access Point Infrastructure network setup, where a device acts as a communication hub for users of a wireless device to connect to a wired LAN.
This chapter provides general instructions on how to set up each of these systems. The examples
provided are suggested ways of positioning the equipment. You may alter the component setup as
needed.
Alice 5 Equipment Setup

2.1 Before You Begin
Before you set up your Alice 5 system, keep the following information in mind:
•
Map out your facility’s layout in advance so you know what type of equipment, cables,
and accessories you will need.
•
Determine whether you will be setting up a wired or wireless network for Alice 5. If you
will have a wired network with multiple devices connected, you will need a switch.
•
Respironics recommends that you set up the Alice system on its own network, independent of your facility’s network(s). System performance may be better on an independent
network.
•
Your cabling requirements will change depending on whether you use a point-to-point
setup or a network setup. You will need a CAT-5 Crossover cable for a point-to-point
setup, while a network setup requires a standard CAT-5 Patch cable.
•
The Alice 5 system does not support the Dynamic Host Configuration Protocol (DHCP),
a protocol for assigning dynamic IP addresses to devices on a network. You must assign
static IP addresses to your Alice 5 devices and to the computers you are running the Alice
Sleepware software on, as well as to any network video cameras or servers you use. See
Chapter 3, Software Installation and Setup, for additional information.
2.2 Setting Up Your Network
This section describes how to install your system using wired or wireless networks.
2.2.1
Network Setup Examples
This section provides example illustrations of various setups that are commonly used when
configuring Alice 5 networks. There are many possible configurations, but these will help you
understand some of the basic connections and how the IP addresses are set up. The different
wired and wireless setups are described in greater detail in Sections 2.2.2 – 2.2.4.
Note:
2–2
It’s recommended that you first map your network setup before proceeding with the
equipment installation instructions later in this chapter and the software installation
described in Chapter 3. You will need to determine what your network configuration is
and what equipment you’ll be using (if you’ll need a switch, a video server, etc.) before
you start setting everything up.

Using a Point-to-Point Setup
If you plan to connect the Alice 5 base station directly to the computer you will be using to view
data, you may want to use a point-to-point wired setup or an ad-hoc wireless setup to install the
equipment.
Figures 2–5 and 2–6 show point-to-point and ad-hoc setup connections. In Figure 2–5, one
desktop computer is directly connected to an Alice 5 device using a CAT-5 crossover ethernet
cable.

Complete the following steps to set up your Alice 5 hardware. Refer to Figure 2–12 for a detailed
example of how the final room setup might look.
1.
If you haven’t already done so, unpack your computer and set it up according to the instructions supplied with it.
2.
Unpack your Alice 5 system and make sure that all of the components are included.
3.
Make sure that the base station is placed on a flat, stable surface close enough to allow for
easy connection to the headbox. The base station should also be placed within easy access to
an external AC power supply that is properly grounded.
4.
Place the headbox on a table or stand above and behind the patient’s head, beside the patient’s
pillow, or on a nearby hook using the carrying strap supplied with your system. Or, use the
mounting bracket to mount the headbox on a wall.
5.
Connect the power cord to the AC power supply.
6.
Plug the pronged end of the power cord into a wall outlet.
Caution:
Never use an extension cord with the Alice 5 system. Always operate the device
using a properly grounded AC power outlet. If you are unsure whether a power
outlet is properly grounded, contact an electrician for assistance.
7.
Connect the power supply’s cord into the Power Connector port (

The ends of the Patient Cable are interchangeable. It does not matter which end you
plug into the base station and which end you plug into the headbox.
Note:
10. Follow Step A for point-to-point wired setups, Step B for wired network setups, or Step C for
ad-hoc or access point infrastructure setups.
A. For Point-to-Point Wired Setups:
–
Plug a CAT-5 crossover cable into the Network port (
station.
) on the back of the base
–
Then, plug the remaining end of the cable to your computer’s network interface
connector.
B. For Wired Network Setups:
–
Plug a standard CAT-5 Patch cable into the Network port (
base station.
) on the back of the
–
Then, plug the remaining end of the cable into an ethernet connection. For example,
if you have set up your network switch in your control room, you can run the CAT-5
Patch cables from the base stations in each patient room to the ethernet connectors
on the switch, so that all base stations are plugged into the same network.
–
To connect your computer to the network, plug a CAT-5 Patch cable into your
computer’s network interface connector, and plug the other end of the cable into an
ethernet connection (e.g., a connector on a switch).
C. For Wireless Ad-hoc or Access Point Infrastructure Setups:
Note:
–
Plug a standard CAT-5 Patch cable into the Network port (
base station.
) on the back of the
–
Then, plug the remaining end of the cable into an ethernet connection.
In Step C, although you are configuring a wireless setup, you still need to perform this
step when initially setting up your Alice 5 system. For network security reasons, the
wireless feature is disabled when you first receive your Alice 5 device. In order to
enable the wireless feature, you must first set up the device as a wired connection to
allow your device to be seen on the network. Then, after you enable the wireless
feature via the Sleepware software, remove the ethernet cable. Once the wireless
feature is enabled, the system uses the wireless antenna attached to the Antenna
connector ( ) on the back of the base station to transmit data.
11. If you are using a microphone for intercom/ambient sound recording, plug the male end of the
Microphone cable into the Microphone connector (
) on the back of the base station. Plug
the remaining end of the Microphone cable into the microphone you are using on the patient.

Once you install Sleepware and add your Alice devices (as described in Chapter 3),
you can enable the audio feature by right-clicking on the Room button located on the
Starter bar and selecting Audio/Video Settings from the drop-down menu. See Section
2.4, Adding Accessories, for instructions on setting the audio and video settings.
12. If you are using speakers with your system, connect the green, male end of the Speaker cable
into the Speaker Connector (
) on the back of the base station. Connect the other end of
the cable directly into any basic-powered PC computer speaker.
Note:
If the technician is in a control room separate from the sleep lab, the speakers and
microphone allow the technician to speak directly with the patient from the control
room. The speakers and microphone work in the same one-way format as an intercom.
Once you’ve installed the speakers, if you want to change the volume, you can adjust the
volume control on the speakers or you can use the volume control setting on your computer.
13. To connect a Respironics therapy device (CPAP, Bi-Level, etc.) to the Alice 5 system, connect
the serial connector end of the therapy device’s Communications Cable into the Com 1 Serial
) on the back of the base station. Connect the remaining end of the
Connection port (
Communications Cable to the port on the back of the therapy device or to the Sleeplink card,
if applicable. This allows you to control the therapy device directly through the Alice 5
system. Refer to the therapy device’s manual for connection information.
14. If desired, you can connect additional external medical devices, produced by other manufacturers, using the Auxiliary Input connectors on the back of the base station. Refer to these
devices’ manuals for additional information.
Note:

2.4 Adding Accessories
There are many additional accessories you can use with the Alice 5 system. See the Respironics
Diagnostic Accessory Guide for details on the many accessories available.
This section provides instructions on how to set up video cameras and video servers with the
Alice 5.
2.4.1
Installing Video Cameras and/or Video Servers
You may want to install video cameras and/or video servers to use with your Alice system. There
are a few setup options when using video cameras with the Alice 5 system:
•
Connect a video camera directly to the base station if your Alice 5 equipment is communicating with your computer through a wireless interface.
•
Connect a video camera to a switch on your network.
•
Connect multiple video cameras (up to four) to a video server that is connected to your
network’s switch or hub. You must be using a network switch with your Alice 5 system to
use a video server.
Note:
If your computer is wired to the base station, or if you are using a network switch that
is wired to the base station, you cannot connect a camera directly to the Alice 5
device.
Note:
See the Respironics Diagnostic Accessory Guide to determine what video server is
compatible with the Alice 5 System and to order video cameras if needed. Refer to the
instructions included with your video server for more detailed product information.
Decide which option you want to use, and then follow the installation instructions below.
1.
Connect your video equipment to the Alice 5 system using one of the following three configurations:
a.
If you are connecting a video camera directly to the base station, connect a CAT-5
crossover cable to the network connector on the video camera, and connect the other end
of the cable to the Network port (
) on the back of the base station.
b.
If you are connecting a video camera to your network switch, connect a CAT-5 patch
cable to the network connector on the video camera, and connect the other end of the
cable to one of the ports on your switch.
c.
If you are connecting one or more video cameras to a video server:
–
Connect a CAT-5 patch cable to the network connector on the rear panel on the video
server, and then connect the other end of the cable to an ethernet connection on your
switch.
Alice 5 Equipment Setup
2–17
–
If your camera has a BNC connector on it, connect a coaxial video cable to one of
the video inputs (BNC connectors) on the front panel of the video server, and
connect the other end of the cable to the BNC connector on the camera. Repeat this
step if you are adding more than one camera.

(BNC Connectors)
Figure 2–15 Video Server Front and Rear Panel Connections
Note:
2.
If your camera does not have a BNC connector and has a standard phono-type RCA
connector instead, you will need a BNC-to-RCA converter to connect the camera to the
video server.
Note the serial number on your video camera or on the bottom of the video server if you are
using the server. You need to know this to set the IP address.
Note:
If you are using a video server, you only need to assign the server an IP address, not
the cameras. However, if you are connecting a camera directly to the base station or to
a switch, assign an IP address to the camera.
Note:
The serial number on the video equipment is the same as the MAC/Ethernet address
you will enter in step 3 below (e.g., 00408c100086 = 00-40-8c-10-00-86).
3.
2–18
From a computer on your network, assign the video camera or video server (depending on
your setup) a unique IP address:
•
From your Windows operating system, start a DOS window by going to Start>Run and
typing cmd in the text box that appears. Click OK to access DOS.
•
Type the following command in the window that appears:
