1 Introduction to the Actiwave System
1.1 An Overview
of the
Actiwave
System The Actiwave system is designed to offer maximum
flexibility for the recording of physiological waveforms.
Instead of one bulky multi-channel recorder, the Actiwave
devices are available in 1, 2 or 4 channels and are
physically small enough to be located close to the
measuring electrodes.
Components required for a system
The Actiwave system consists of 3 main components:
One or more Actiwave recorders with appropriate
electrodes.
USB Interface Dock.
PC Software providing set-up, download and
maintenance functions.
The Actiwave Recorders
There are five variants of the Actiwave recorder; the basic
functionality of each variant is summarized in the table
below:
Actiwave Model

* Example recording times are based on 128Hz sampling with
8 bit resolution unless otherwise specified
** Three axes acceleration sampled at 32Hz, 10 bit.
*** Three axes acceleration sampled at 32Hz, 8 bit.
Actiwave Electrodes/Subject
Connections
The Actiwave recorders (with the exception of the Cardio)
have 1mm male contact pins to mate with 1mm female
sockets attached to the electrode cables. The use of 1mm
pins/sockets helps to reduce the physical size of the
Actiwave in use.
There is a vast range of third party electrodes available to
suit specific applications. Typically third party electrodes
will be fitted with 1.5mm female sockets which are not
directly compatible with the Actiwave. To counter this,
CamNtech offer the following solutions:

The Actiwave Cardio is
designed to be worn on the
upper or lower chest (see
photo). The Cardio is equipped
with spring loaded contacts to
allow direct connection to the
standard 4mm studs found on
ECG electrode pads.
The choice of electrode pad will
depend upon the application. The Actiwave Cardio can be
comfortably worn for several days.
For further information regarding electrode types and
electrode placement, see section 6 of this manual.

2 Installing the Actiwave Software
2.1 System
Requirements
The Actiwave software is supplied on a CD ROM
containing all of the components of the software package
including the USB drivers for the Interface Dock. The
following are the minimum requirements of a host PC for
installing the Actiwave software:
IBM compatible 1000MHz +
Windows XP, Vista, 7 or 8 operating system
100 MB hard disk space
USB port
A CD-ROM drive or equivalent
Graphics (1024 x 768 pixels minimum)
In general, a faster processor will provide superior
performance.
2.2 Installing the
Software
Place the CD ROM into the drive; the Actiwave software
installation menu should start automatically as shown
below:
If it does not start automatically (this functionality is
sometimes disabled for security reasons) you will need to
browse with Windows Explorer to view the CD ROM then
double-click on the file ‘SplashScreen.exe’.
Follow the installation wizard’s onscreen prompts until the
installation is complete. It is recommended that you install
the software in the default location. The operation of this

Actiwave User Guide - Issue 2.0.18 Page 12
software on a remote server is not guaranteed as network
settings vary considerably.
The software should not be started until you have
connected the reader and installed the drivers required by
the USB reader charger (see Section 2.4).
Please note the copyright warning. By accepting this, the
user is accepting the CamNtech terms and conditions of
use of the Actiwave software
2.3 Updating the
software.
If you are updating or reinstalling the software you should
remove the old version first when prompted by the
installation wizard. The installation has to then be
restarted by removing and re-inserting the CD ROM or by
double-clicking on the Actiwave.msi file.
2.4 Installing the
USB drivers
for the
Interface
Dock
This section on installing drivers only applies to new
installations.
Insert the supplied CD ROM into the CD/DVD drive on
the host PC and plug the Actiwave reader/charger into a
free USB Port.
The installation menu will automatically be displayed
(see Section 2.2).
Depending upon the operating system and current
driver status, the computer may display a message saying
‘Found New Hardware’ and should then load the drivers
with no user intervention. The installation menu can be
cancelled in this case.
If the drivers do not load automatically, or if you wish to
make sure they install correctly, you may choose ‘Install
CamNtech USB Drivers’ from the installation menu and
then carefully follow the instructions on-screen.
If you have difficulty, consult the procedure; ‘Installing
USB Drivers Manually’, which is included in Appendix 2 of
this manual.
A screen may appear that tells the user that the driver
is not digitally signed by Microsoft:
Select ‘Continue Anyway’ (Please note that this is NOT
a problem and just means that the Actiwave version of the
driver software has not been assessed by Microsoft. In
fact the actual drivers are Microsoft approved).

Actiwave User Guide - Issue 2.0.18 Page 13
The drivers will be installed and the computer will then
tell the user that the new hardware is ready to use. If you
change the USB port that the reader is plugged into then
the driver may be automatically re-installed by Windows.
This is an automatic process and the user need take no
action.
2.5 Running the
Software for
the first time
The USB drivers must be installed before using the software
for the first time.
Double clicking on the Actiwave icon on the desktop will
start the software. If a dock is plugged in it should be
detected and a view of it shown on screen. Three types of
interface dock are shown in the figures below:
Multi/Motion Dock
CombiDock
CardioDock

Actiwave User Guide - Issue 2.0.18 Page 14
3 Connecting the Actiwave & Charging the
Battery
3.1 Overview Before the Actiwave is used for data collection, the user
must ensure that it is fully charged. A depleted battery may
result in an incomplete recording as the Actiwave may shut
down before data collection is complete. If the battery is
below 3.7V, a warning message will be displayed if set-up
is attempted.
The Actiwave contains a lithium polymer rechargeable
battery. The expected duration of the battery from fully
charged is dependent on the type of Actiwave and the
recording mode but is always in excess of 2 days. The
Actiwave may be recharged via the USB port of the Host
PC or using a standard mains adaptor with a USB Type A
connection (e.g. those used with MP3 players etc.).
3.2 Correct
orientation
and position
in the dock The Actiwave devices must be correctly oriented and
located in the correct position within the slots of the
interface dock. The Actiwave devices (not Cardio) have a
profiled case to ensure correct orientation. Furthermore,
the Actiwave should always be fitted into the topmost
position within the slot (see figures below). Always take
care to align the pins with the holes inside the slot and do
not use excessive force or the pins may be damaged.

3.3 Charging the
Actiwave
from the PC There are two modes of operation when the dock is
connected to the PC (and the PC is switched on):
1. Stand-alone mode: The Actiwave software is not
running; the Actiwave devices are charged and their
charge status is indicated by the LEDs on the dock. While
the Actiwave is charging, the LED will be RED. When the
Actiwave is charged, the LED will stay GREEN. Note that
the status will alternate between charged/charging as the
charge level rises, and occasionally show red in order to
maintain full battery charge.
2. Managed Mode: In this mode, the Actiwave software is
running on the PC. The main display will show a bar graph
of the approximate battery level on the respective channel.
An Actiwave which has been used should be left charging
on the reader for a period of several hours, if you require it
fully charged. The estimated battery level shown may not
be fully accurate during charging itself, so it is advisable to
leave the unit connected and charging for some time if the
indication has reached green after only a short period.
