NTRODUCTION
This is an instruction manual for the operation and maintenance of the
VitalSense Integrated Physiological Monitoring System. This wireless
system consists of the following components:
VitalSense
Components
• Monitor
• Dermal Patch Sensor
• Capsule Sensor
Once a sensor is activated, it measures temperature data four times per
minute, and reports on average of four times per minute to the monitor.
The temperature data is timestamped and recorded for the measured time.
Up to ten sensors may be monitored. In order to do this, each sensor must
be activated by the monitor that will be recording that particular sensor.
During activation, each sensor and the monitor are synchronized.
IMPORTANT!
•Section Two of this manual explains the operation of the VitalSense
System as controlled from the front panel of the VitalSense monitor.
This is a “stand alone” section independent of Section Two, assuming
you are operating VitalSense from the monitor front panel.
•Section Three of this manual explains the operation of the VitalSense
System controlled from the Application Software. This is a “stand
alone” section independent of Section one, assuming you are operating
VitalSense from the Application Software.
1-2 Introduction
Sensors
VitalSense sensors are activated from the VitalSense monitor. Once
activated, a sensor will begin its monitoring assignment, and will continue
to do so until the battery expires (approximately 240 hours), the sensor is
removed from the sensor schedule, or the sensor is disposed.
Sensor activation is a key event in the operation of VitalSense. It is used to
synchronize the monitor with a sensor. Once activated, the monitor can
display the incoming data in real-time streaming, or log the data to the
non-volatile memory for future transfer to a computer.
Each sensor is given an identity number at the factory, along with
temperature calibration data. During activation, these data are retrieved
from the sensor and stored in the monitor memory.
All sensors are activated using essentially the same process:
• A specific optical signal from the monitor activates the sensor.
• By radio, the sensor transfers its identification and calibration data to
the monitor.
Following activation, the sensor is either swallowed (Capsule Sensor), or
affixed to the body (Dermal Patch Sensor). The activation process is
identical for each sensor.

Initial Monitor Setup for Data Collection
Before data collection can begin, the monitor must be set up, or
configured. This configuration can be done from the PC through the RS-
232 port of the monitor, or from the monitor front panel. This section will
cover monitor front panel operations.
There are four operations that should be accomplished to assure the
monitor will collect data:
• “ Set to Factory Default ” on page 2-3
• “ Adjusting the Time/Date ” on page 2-6
• “ Erase Data Memory ” on page 2-11
• “ Activating Sensors Using the VitalSense Monitor ” on page 2-15
Some or all of the first three items may not be necessary if, for example,
you have configured VitalSense previously, erased the memory, or if you
have already set the time.
Set to Factory Default
This procedure insures that during initial setup, the default settings are
displayed and the subsequent setup procedure can be followed without
confusion.
1Press the power button on the Monitor front panel. The following Main
menu will appear.

Time and Date Time and date must be set carefully. VitalSense data is collected with
UTC (Universal Coordinated Time) as a reference. However, the monitor
can display Local time as well as Daylight and Standard times.
If the UTC or Local times, and the UTC offset are entered correctly,
VitalSense can compensate between Standard and Daylight time, and take
into account your PC’s clock.
CAUTION! When collecting data from sensors which are on line, do
not change the time setting or the sensor may be lost.
A note on UTC UTC, or Universal Coordinated Time, is based on precise atomic clocks,
shortwave time signals, and satellites. This insures that there is a reliable,
accurate standard for scientific and navigation purposes.
The difference between local time and UTC is called the UTC offset.

Establishing RS-232 Communications
When there is a failure to communicate, typically the cause of one of two
major COM port errors:
• COM port is already in use.
• General communication errors
COM Port Already in Use
The VitalSense monitor default COM port is COM1. If the following error
appears, the COM1 port must be changed. This is done by editing the
configuration file.
COM port warning
1Open the configuration file using Wordpad, Notepad, etc. This file is
located in the VitalSense installation folder:
Program Files\VitalSense\vitalsense.cfg
2Change the second line in the file to match an available COM port, e.g.,
COM2.
3Save the file and restart VitalSense.
General Communication Error
In this type of error, the program can open the serial port, but cannot
establish communications with the VitalSense monitor.
COM port warning
1Check the serial cable connection at the PC, and at the VitalSense
monitor.
2Verify the default baud rate of the VitalSense monitor is set to 57.6K.
This can be found from the monitor front panel:
SETUP > RS-232 INTERFACE > BAUD RATE: 57.6K
3-6 Monitor Operation - Application Program
3Additional information can be obtained by opening the VitalSense
console window. This diagnostic information may be of use to you, or
in case you need to contact Mini Mitter Technical Support.
VitalSense console
Once communication has been established via the RS-232 cable, setup and
data collection can begin.

Initial Monitor Setup for Data Collection
This procedure is very similar to portions of “ VitalSense Monitor -
Operation from Front Panel ” on page 2-1. This section, however, contains
instructions on additional functions, such as retrieving data and real time
obsservation of data collection.
Before data collection can begin, the monitor must be set up, or
configured. This configuration can be done from the PC through the RS-
232 port of the Monitor.
There are three operations that should be accomplished to assure the
monitor will collect data:
• “ Options - Clear memory ” on page 3-9
• “ Setting the Clock ” on page 3-10
• “ Subject Information ” on page 3-11
Some or all of the items may not be necessary. If, for example, you have
configured VitalSense previously, erased the memory, or if you have
already set the time.

Monitor/Sensor Setup
Setup begins with the Main display, and the Setup menu.
COM Port
If necessary, you may change the COM port by clicking on Comm Port,
and follow the directions.

Options - Clear memory
If you are beginning a new data collection session, it is recommended that
you first erase the data memory. The data memory only pertains to data,
not the sensor or subject information.
NOTE: If you plan to change or delete subjects, this step may be
skipped. You will be given the opportunity to clear the data memory
at that time.

3-16 Monitor Operation - Application Program
A Data Collection Summary will appear. This is essentially an “index” of
the data collected.
Data Collection Summary
NOTE: If you choose not to generate a report at this time, you may
use the Open File command and generate a report at a later time.
VitalSense Data Collection Summary
The table of sensors as shown above contains the following information
for each sensor listed:
• Sensor ID.
• Timestamp of first data record for that sensor.
• Elapsed time to the last data record for that sensor.
• Total number of packets, or measurement records.
• Number of lost packet (records with a timestamp outside the allowable
window.
• Number of recovered packets (a missing measurement recovered from
the “previous value” field on the next data packet.
• The number of CRC errors.
3-17
The data summary also includes the following functions:
• Extract check box selects the data you want to see.
• Data Collected in Medic Mode check box. When checked, lost packet
detection is disabled, since it is unknown when a packet is expected to
arrive.
• Generate Report starts the file extraction and decoding process.
• Cancel disables this function.
Generate Report
Two output files will be generated:
• A Microsoft Excel file with an .xls extension. The filename will remain
identical to the original Read Data filename.
• A plain text file with a .txt extension. The filename for the text file will
be comprised of the original Read Data filename, along with “_d_nnn.”
“nnn” is the sensor number.
Both files will be named after the original Read Data filename. To change
the filename, rename it using Windows Explorer.
