Description of the components

The Trackit Mk3 recorder

The Trackit Mk3 is a multi-channel recording device designed for use in recording a patient’s E EG
signals. It comprises a 24-channel EEG (monopolar) amplifier acquisition board, an 8-channel poly­graphic acquisition board and contr ol b oa r d with all the I/O inter face for serial an d patient commu­nication. When connected to a host PC , the device has built-in is olation for patie nt safety. The de­vice may be powered either by its ow n batteries or a PC USB port. EEG data is stored on an inter­nal CF card. The data format is native European Data Format (EDF) , allowing the EEG files to be
reviewed by any EDF-compatible EEG reader.

Patient Connection Unit

The Patient Con nection Unit (PCU) connects the stan dard 1.5mm touchproof EEG recording elec­trodes attached to the patient to the Trackit Mk3 unit. It is available either as a ‘Cabled’ type which
is connected via a screened cable or a ‘C lickon’ type which fits on the Trackit Mk3 directly without
needing a cable.

WARNING: Lifelines does not supply EEG electrodes. T he PCU accepts st a nda rd 1.5 mm
touchproof elec t r odes using DIN 42802-style connectors. To ensure pati ent safety, the
electrodes used must be approved to the Medical Device Directive 93/42/EEC in Europe

Functions of the setup software:

 Download the recording template. This includes:

which electrodes are turned on or off;
the recording montage;
any timed recording modes.

 Download the un ique patient identifier onto the card so tha t no confusion can arise as to whom

the recording belongs to.

 Perform a calibra tion of the Track it Mk3 device
 Synchronise the Trackit Mk3 time and date to that of the host.
 Perform a routin e EEG recording prior to the patient’s am bulatory EEG recordin g.

What does a recording consist of?

 2–36 channels of recorded E EG/polygraphic signals
 Signals recorded over a period usually not less tha n 24 hours
 Patient event mar kers correlated in tim e with the real time cloc k displayed on Tra ckit Mk3 LCD

likely to be used.
The equipment should not be u s ed w ith high frequency surgica l equ ipm ent.

Other patient-connected equipment

When used simulta neously with other patient-connected equipment, for example a cardiac pa c e­maker or other electrical stimulat or , it is unlikely that a safety hazard will a r ise. However always
consult the docu m entation supplied with the other patient-c on nected equipment to ensure that all
hazards, warnings an d c autions a r e c on s ider ed before the equipment is used to gether.

2.6 Interference

Trackit Mk3 will continue to operate in the presence of r a d io frequency magnetic fields (RF) and the
effects of electrostatic dis charges (ESD) and other in terference, in accordance with the require­ments of EN60601-1-2. However, Trackit Mk3 records signals of very low amplitude, and these s ig­nals themselves a r e not immune to the effects of RF, ESD and low-frequency magnetic field inter­ference. Such interference may cause signal artefacts.

Caution: when in c lose proximity to t he recorder, do not use mobile phones, tra n smit­ters, power transf ormers, motor s, or other equipment t hat generates magnetic fields.
Refer to the Appendix for more informa tion.

Note: Medical electrical equipment needs s pec ia l precautions regarding E M C and needs to be in-

stalled and put into service according to the EMC informa tion provided in the Ap pe ndix.

2.7 Maintenance and cleaning

The Trackit Mk3 contains no user-serviceable parts (apart from replaceable batteries). The system
uses solid-state components a nd requires no routine testing or mainten ance procedures apa rt from
occasional cleaning and checking for wear and damage to all parts including the accessories.

All the outer surfaces of the individua l p ieces of equipment of the Trackit sy stem may be cleaned
using a soft cloth moistened with wate r a nd a mild detergent. Each item may also be cleaned using
a low-pressure air-line or a vacuum cleaner.

Disinfection of the equipment can be carried out by the use of QAC-based disinfectants. Wipes are
recommended in order to prev ent the ingress of any liquid into the equipment. Suitable produc ts
include Mikrozid Sensitive Wipes (Schülke & Mayr GmbH), Microbac forte (Paul Hartmann AG), Dis­tel Wipes (Tristel Ltd.).

Caution: Do not al low any liquid to e nt er the case of any inst r ument or connector.
Do not use acetone on any of the instru ments.

2.8 Disposal of equipment

The expected service life of the equipment is five years. When it has reached the end of its operat­ing life, it should b e disposed of in accordance with local w aste regulation au thority that is typically
within the local gov e r nment office.

4 The setup software

The setup softw a r e is available on CD. A r eadme file describes installation. Check with your distrib­utor or Lifelines if a newer version of software is available.

Trackit setup software is supported on Microsoft Window s 2000 ( w ith SP2), Windows XP, Windows
Vista and Windows 7.

When Trackit Mk3 is connected to the h ost PC, the software a llows the user to define p a rameters
for the recording, such as recording montage, start time and stop time, m ode of recording etc .

The setup softw a r e has the following func tions:

 Define signal type s : create labels to atta c h to inputs
 Attach the desired signal ty pe ( la bel) to the recording input. For ex a m ple , input 1 with a signal

type FP1

 Create a recording montage and down load it to the recorder
 Perform a calibra tion of the inputs
 View signals online and adjust display parameters such as chart speed and display sensitivity
 Start and stop a Trackit recording session

Figure 6 New Patient database

The database allow s you to enter more exten s ive information about the patient and recording, and
save it for future refer ence. See the section entitled ‘Adv a nced options’.

Step 2 Define the signals

Defining signals is usually done once only – before using Track it Mk3 for th e first time. The Trackit
Mk3 recorder arrives w ith a default set of signals that should suffice for most applications in ambu­latory EEG, hen ce it may only necessa r y to a dd s ig nal types for polygraphic recordings (airflow,
respiration etc).

If for any reason the signals have not been created, it is necessary to define all the signals (labels)
that are to be used f or m ontage creation in Step 3. The signal editor allows the creation of up to 64
distinct signals ranging from the standard 10/20 EEG signals such as FP1 O2, to Respiration, Pulse
and other polygraphy inpu ts .

Step 3 explains how to calib r ate an AUX input.

To define a signal:
1 Click the View all signals tab in the Signal editor dialog box . See Figure 7.

Figure 7 Signal list

21

Trackit Mk3 User Manual

2 Double click on the signal you want to edit. This brings up the Signal editor tab), allowing you to

create a relevant signal or label to be en te red into the signa l lis t.

Figure 8 Signal e diting tool

3 Type in the Signal name (e.g. Fp1). N ote that for EEG signals this must be case-sensitive.
4 Select a signal type (in this case EEG).
5 Click on the Change button. The signal is now entered into the list under the View a ll signals

tab.
6 If the signal is not an EEG signal, it ma y be necessary to insert a display sensitivity value by un -

checking the M aster control check box.
Signals that ha ve been defined with their own independent sensitivities appear in red in the

trace display. F urther editing an d ch a nges to these sensitivity values in th e trace display will be

saved back into the signal library.

Caution: editing signals that are already used in an a c tive montage may r ender that

montage invali d. Y ou will need to re-enter the original m ontage in the Set-up rec ord-

ing tabbed dialog box – see steps 3, 4 an d 5.

Step 3 Define the inputs

1 Select the Spanner icon on the toolb a r . This opens the tabbed

Setup Recording dialog.
Spanner icon

2 Under the Amplifier Channels tab select the signals (la bels ) to be

attached to the phy sical inputs.
For example, EEG input 1 may require the label Fp1 and so on

according to the standard 10/ 20 nomenclature.

Double click the ch ann el name and s elect the r elevant sig nal label

from the Setup Hardwar e EE G cha nnel dialog.

Amplifier setup: amplifier setup ac tivates the recordin g inputs in preparation for a recording. For
most applications you n eed per form amplifier setup on ly once – when the sy stem is first installed –
since the amplifier setup is s a ved with the recording montage for f uture recall and usage. See Step
4 below.

If you want to use the recording ch a nnel order defined in amplifier setup, click on Auto Record
Setup in the Setu p R e c or d ing dialog box. You can then skip Step 4 (Define the recording channels).

Overall sampling rate: you can sele c t the overall sampling ra te for EEG channels from the Setup
Hardware EEG dialog (Figure 9). Once a sampling rate has been selec ted f or on e EEG input, you
can apply it to all EE G inputs by putting a checkmark against ‘All EEGs same Sample Rate’. If there
is no checkmark, you can select different sample rates on each EEG input – useful if you want to
apply an EOG signal to an EEG input.

Independent sample rates: if the independent sample rates feature is enabled in the Trackit
Mk3 firmware, it may be activated when required from a checkbox in th e Options dialog box
(choose View > O ther Options).

Notes:
1 Not all review software supports independent sample rates . Check with the vendor that your re-

view software does suppor t th em .
2 The Trackit Mk3 firmware must b revision 2.1.X or la te r .
3 It may be necessary to enter an unloc k code into Trackit Mk3 to enable this feature. If the fea-

ture is not enabled, a warning m es s a ge a ppea r s w hen a setup is sent to the recorder.

To enable multiple independent sample rates in the recorder:
1 Click on Trackit Control Panel in th e Trackit toolbar.
2 Click on Advanced Operations, then choose Configu r a tion from the Setting s Menu.
3 Copy the key code and email it to your Lifelines re pr esentative stating that you wish to have the

multiple independent sample r a te f ea ture enabled. You will then r ec eiv e ba c k an activation code

that you shou ld c op y and paste into the empty Trackit configur ation string field .
4 Press the Set Trackit button to enable the feature.
5 Choose Other Options from the Vie w Menu, and put a checkmark in the Allow Multi-sample rates

check box.
Poly and AUX inputs: poly inputs are low-le vel inputs, just lik e the EEG inputs, but dif fer in that
they can be set to either referential (EEG mode), bipolar AC or bipolar DC. They are ideal for p oly­graphic signals such as respiration, airflow, EKG, body position (DC mode) etc. See the table in ap­pendix 2 describing the inpu ts a nd their application.

The AUX inputs are high-level DC , and should not be us ed for low-level signals obtained from
transducers such as passive respiration sensors (piezo electric), airflow thermocouples etc. The
AUX inputs are designed to receiv e a high-level isolated DC signal (calibra ted output from a CPAP
machine, oxygen saturation meter etc).

To calibrate an AUX input to reflect a required unit of scale for a given voltage input use the signal
editor - see Figure 8). Select the appropriate u nits, e.g. %, or mm Hg, and enter the Physical Sig­nal Amplitude required to generate the Amplifier Input Voltage.

Step 4 Define the recording channels

Step 4 can usually be skipped, s in c e the Auto Record Setup button w ill copy what you have defined
under the inputs in Step 3 into the list of recording chan nels.

However, you can defin e an d s a ve recording montages for spe­cific recording needs, and recall them for f uture usage. You can
define up to 40 recording cha nnels in a montage.

Creating a montag e follows the same principle as the signal
creation and input definition tool: c lick on the channel number
to define the active and reference label of choice. See Figure

Special Lithium Battery Instructions for Use

• The battery pack is a Canon Type BP511 and uses rechargeable li th ium ion batteries. Always
refer to the documentation that ac companies the batter y for more information.

• The battery can only be charged outside the Trackit Mk3. Only the specific Canon charger for
the BP511 must be used. Lifelines do not su pp ly the charger; this is available from your lo­cal camera or video s tockist. Alway s r e fer to the documentation that accompanies the
charger for charging instructions.

34

Trackit Mk3 User Manual

• Operating time will be shorter than usual at low temperatures. The battery can be used be-
tween 0 C and 40 C, but will give best performa nce between 10 C and 30 C.

• If the battery starts to give less operating times than usual, it has reached the end of its life
and must be replaced.

• The battery can be recharged at any time. However, since the battery will naturally dis-
charge itself over a p eriod of time, it is best to c harge the battery a d a y or two before plan­ning to use it.

• Always attach the battery terminal c over when not in use . Do not allow any metal objects to
touch the battery ter m inals.

WARNINGS:

• Only use the Canon Type BP511 with the Trackit Mk3

• Keep the battery pac k away from fire

• D o not expose the battery pack to temperatures greater than 60°C

• D o not disassemble or modify the batter y pa ck

• D o not drop the battery pack or allow it to become wet

• Only use the specific Canon battery c ha rger for use with t he BP511 type ba tt ery

5.3 Event marking

Once a recording has commenced, the button on the front pa nel of Trackit Mk3 acts as an event
marker. Events are stored in a n event file (filename.tev), from which on review the events are in­serted into the displayed d a ta.

You can view events before r eplaying the recording using your EEG review program or the
Eventit.exe program that comes with the Trackit installation.

Trackit Mk3 can record 15 different event types. These can be seen by looking at the Tra c kit event
types in the online event viewer. See T r ackit Events, in S tep 9.

5.4 Ending a recording

To stop a recording:
1 Connect the Trackit Mk3 to the host softwa r e .
2 Click on the Stop Recording button in the Trackit control panel.

38

Trackit Mk3 User Manual

Alternatively , to stop the Trackit Mk3 rec or din g in the field:

Either press the button on the front panel and hold it for approximately 5 seconds;
Or simply remove the card an d do not replace it. The idle time by default is only 5 minutes and can

be set in increments up to 255 minu tes – see Advanced Settings, below .

5.5 Identifying a recording

It is not possible to re c ord more than one tes t on a single card. This test is uniquely iden tified by
the Patient ID entered duri ng the setup procedure, and
by the user-definable file n a me.

5.6 Advanced Settings

There are two menus under the Trackit Con tr ol Panel:

 Other Commands
 Advanced Operations

Other Commands

Other Commands duplicates some of the controls on the Trac kit toolbar and recording control.
There are also miscellaneous controls for:
Set Trackit Time/Date: if the Trackit Mk3 is not recording, this manually sets the Trac kit’s time
and date to that of th e PC. Note: this fun c tion is normally done autom a tically when r e c or d ing is
started.
Get Trackit Set-up: this manually retrieves the setup from the Trackit’s memory and overwrites
the currently loaded setup on the PC. Note: this function is normally don e automatically whenever
the software detects a misma tch between the Trackit’s setu p a nd the PC setup.
Quiet On: if a host P C is connected, this tempor arily disables th e warning beep if the battery door
is opened while the Trackit Mk3 is turned on. It is automatically re-enable d a fter the PC is discon­nected.
Quiet Off: if a host PC is connected, this re-en a bles the warning beep if the battery door is opened
while the Trackit Mk3 is turned on.

Advanced Operations

Advanced Operations contains entries, some password-protected, that change the way a Trackit
Mk3 records its data. These settings include:

 Compensation for D C offsets
 Adjusting the idle and recor d time
 Enabling Auto start mode

etc.
To see the available option s under Advanced Operations:

1 Click on the Trackit Control Panel in the Trackit toolb ar.
2 Click on Advanced Operations.
3 Click on Settings.

Set Trackit Defaults

[> Advanced Operations > S ettin gs > Set trackit Defaults ]

Caution: please read the manual carefully before c ha nging or updating the Trackit De­faults. If you want to enable auto-start from flash card or append feature s, make sure all
the checkboxes in Trackit Defaults are checked.

Trackit Mk3 User Manual

Trackit Defaults Tab 1

This menu item activates a control dia log that adjusts how the Trackit Mk3 behaves during a re­cording. See Figure 33.

Figure 33 Trackit Defaults Tab 1

To save new defaults to Trackit Mk3, press ‘Send these values to Trackit’, f ollo wed by ‘Save current
values’.

The following functions are supported:

Idle Mode: Trackit Mk3 turns itself off after a defined period when not recording.
Record Mode: Trackit Mk3 turns itself off after a defined period after having recorded. Trackit Mk3

waits for a defined period for a c a r d to be reinserted to append to an existing f ile which is <24
hours old. Other wise it starts a new recording on a blank ca rd. 60 minutes is enough for a user to
remove a card, re a d it a nd reinsert it to continue recording until the card is full.

Trackit Address: sets the serial address of the Trackit Mk3 if a simple serial network is configured
with several Trackits connected to on e P C.

BU battery auto char ge : enables fast-charging of the backup battery when the Trackit Mk3 is
connected to its ex te r nal power supply .

Warn if <8 mins card time: the Trackit Mk3 starts beeping when the card has room for only an­other 8 minutes of recordin g.

Allow card setup auto execute: allows a setup to be stored onto a flash card for a r ecording to
start automatically only when th e Trackit Mk3 is switched on. See Ways to start a recording, in
Step 8.

Allow auto record (overwrite): when this box is checked the Trackit Mk3 automatically over­writes any data on a card ins erted during a recording (e.g. when changing cards during a record­ing).

Allow auto record (a ppend): if a card is inserted with a file which has the same patient name
and is less than 24 hours old, Trackit Mk3 appends to rather than overwrites the data. This is a
very useful feature if a recording is interrupted, say for a quick r eview of the data. Trackit Mk3
waits in record mode, and when th e card is reinserted it car r ie s on recording to th e e xisting file on
the card.

40

Trackit Mk3 User Manual

Allow auto record (blank card): check the box if you routinely w a nt recordings to take place
over several blank cards. This is a very useful feature if a recording over several days is required.

Allow external events: an external event marker can be attached to the Au x. port.
Allow IRed eve nt s: the optional Trackit infra-red even t ma r ker (Trackit Mk 1 only) can be used to

annotate a recordin g .
Immed. card load (or at door close): off by default, allowing the ca r d to b e loaded only when

the rear door is shut. Leave this box unchecked if you want to mak e rec or din gs over several cards
on a regular basis.

3 button Off (or 2): unchecked by default, allowing Trackit Mk3 to be turned off using only two
button presses (on/off button and down arrow button s im ultaneously). Trackit Mk 1 only.

All new Trackits have all the logic functions enabled by default except Immed. card load and 3 but­ton Off. To update the logic functions in the Trackit Mk3 recorder when changes are made, click on
Send values to Trac kit, followed by Save current values. This saves the values in the Trackit
Mk3’s non-volatile memory. See Figure 33 above.

Trackit Defaults Tab 2 (Mk2 and Mk3 only)

The Trackit Mk2 and Mk3 have additional optional parameters. These are accessed via Tab 2 of
Trackit Defaults, as shown in Figure 34 below.

Figure 34 Trackit Defaults | Tab 2

Save/Restore setup and Auto-record

The Trackit Mk2 and Mk3 have much increased internal non-volatile memory. This memory a llows
it to save its entire Setup before powering-off. When next powered-on, it is able to restore its la st
saved Setup. This feature can significantly speed-up the download of a Setup to the Track it be­cause the Host software automatically determines if the T rackit is already Setup correctly.

Another benefit to this save/recall of Setup is that the T r ackit can resume rec or d ing in exactly the
same state is was in the last time it was powered-off. This is especially useful if, during a record­ing, the User tak e s a long time to replace the batteries. To contr ol this feature, the following op­tions are available:

41

Trackit Mk3 User Manual

• Save/Restore setup after power-off. When checked, this enables the Trackit Mk3 to save its
entire Setup including Pati ent Name and Recording ID after power -off and recall it at power-on.
Note that the Patient Name and Recording ID are only retained f or 15 minutes after power-off
(refer below).

• Auto-record afte r r e st ore setup at powe r-on. When checked, this enables the Trackit Mk3
to continue recording if it was recording the last time is wa s powered-off, using the recalled
Setup and Patient Name an d R ec or din g ID, but only if it has been powered-off for 15 minutes
or less. If the Trackit Mk3 has been powered-off for lon ge r than 15 minutes, then the Patient
Name and Recording ID are overwritten with defaults (th e c urrent Setup remains)Note that the
parameter above must also be checked to used this feature.

• D isable auto-record after manual Trac kit off. When checked, this causes a potential Auto-
record situation to be cancelled whenever the Trackit Mk3 is powered-off either from its ow n
front-panel pushbutton or from the Host.

• D isable auto-record after record off . When checked, this causes a potential Auto-record sit-
uation to be cancelled whenever the Hosts instructs the Trackit Mk3 to stop recordin g.

Note that in all these Auto-record situations, the same rules apply to data storage on the flash card
as defined in the User Manual for the current Trackit Default Options | Tab 1. To summa r is e these
rules:

• The Trackit Mk3 will not record over a data file on the c a r d which is less than 24 hours old.

• The Trackit Mk3 will append new data, if enabled, if the d a ta file on the flash card is less than

24 hours old and the Trackit Mk3’s Setup and Patient Name and Recording ID are identical to
that on the card.

• The Trackit Mk3 will overwrite data on the flash card, if enabled, if the data on the card is m or e
than 24 hours old.

• The Trackit Mk3 will write new data to a blank flash card, if en a bled.

Disallow Nonin Errors

This is a feature a vailable to all Track its running firmware Vx.13.x or later. N or mally, the SaO2
data stored to the flash card is set to an invalid value (127) to m a r k any of the followin g Nonin er­rors:

1. Sensor disconnected

2. Out of track

3. Low perfusion

4. Marginal perfusion

5. Bad pulse

Errors 1 and 2 are serious and do cause invalid data. However, short-term errors 3 to 5 are not so
serious and the N onin device is still ab le to produce meaningful data. The av a ilable option is as fol­lows:

• Disallow Nonin Errors. When checked, all errors 1 – 5 produce inva lid data ( 127) . W hen

unchecked, it is only errors 1 a nd 2 which cause the data to be marked as inv a lid, other­wise the Nonin da ta is unmodified.

Get Card Info

[> Advanced Operations > S ettin gs > Get Card Info]
Selecting Get Ca r d Info opens a dialog showing the current s ta tus of the flash card, including the
file name and any error codes (‘Disk OK’ is displayed to indicate a properly functionin g card).
Should any problem occur with the fla s h card, copy and paste th is dialog and send it to y our Life­lines distributor.

To format a flash card:

42

Trackit Mk3 User Manual

1 Insert the flash card into the Trackit Mk3 and connect to the h ost computer. See Step 6 Connect

Trackit for Setup.
2 Open the Get Card Info dialog box.
3 Choose Format Disk from the Disk Utilities Menu.
4 Click on the Format button.
5 Wait for the format complete message to appear. A 1GB c a r d will tak e a r ou nd 5 seconds to for-

mat, larger cards will take longer to format.

Caution: in normal operation, fl a sh c a rds rarely require formatting. I f formatting is done
on the PC it is easy to inadvertently create the wrong card form a t.

Earlier Trackits with V4.19 firmware and earli er use FAT16 cards only (re ferred to in
Windows as ‘FAT’). If for any reason y ou wish to format a fla sh c a rd, make absolu t e ly
certain you know wha t you are doing! It is easy to convert from FAT16 to FAT32, but
very difficult t o c onv ert the other way (the c a rd has to be manual ly re-partioned and r e ­formatted). In the rare circumstances that it is necessary to format a flash card, use the
inbuilt Trackit format utility.
Later Trackits fitted with firmware V4.21 and later use F AT 16 or F AT32 cards and there
are format facilities in the Trackit to support both types.

Factory Settings

[> Advanced Oper a tions > Settings > Fa c tor y Settings]
Factory settings a r e protected by a pass word (via Other Option s in the View Menu). O nly trained
support staff should have access to factory settings.

Factory settings a lso allow you to comp ensate for any DC offsets that may be present on any of the

5.7 Reading an ambulatory recording

Click the ‘Open a ll playback files’ bu tton on the left hand side of the Trackit softw are toolbar (refer
to Figure 14 on page 25) to playback a recording.

It is possible to lau nch a second instan ce of the Trackit softw are and view an on-going ‘Record to
PC’ file. If th e on-going file is located in a s hared folder it is pos s ible to view the file a c r oss a local
network.

As an alternative to the Trackit software which offers basic playback features, any EDF-compatible
viewer can be used to read the s tandard EDF files recorded by the Trackit Mk3.

All Trackit record ings have a user-definable 8-character file name. They are stored in EDF format,
readable in all EDF-compatible EEG browsers. In an EDF-compatible browser, the pa tient’s name
and recording ID are displa yed in the test properties.

Lifelines currently recommends:

 Nihon Kohden 1100 and 1200 EEG
 Neurotronics Polysmith Sleep softw are
 Nicolet One EEG

This facility enables EEG data from the Trackit Mk3 to be recorded directly to the PC. Headbox
mode must be enable d in Advanced Opera tions in the Trackit Control Panel.

1. Connect to the Trackit Mk3 and setup in the norm a l wa y. Connection can be either USB, or

Bluetooth.

2. Click the Record to PC button

3. Specify a storage location on the PC for the EEG data file.

4. Enable, if desired, ‘Trackit auto-record when host comms los t’. The Trackit Mk3 will automat-

be particularly useful when a Blue tooth link is being used.

2 Network Connection

There follows an explanation of how to remotely connect to th e Trackit Mk3 and acquire data over
a TCP network.

Overview

The diagram below shows how the system w or ks. The Trackit applicat ion runs on the server PC
which is connec ted via serial or Bluetooth to a Trackit Mk3 device. A r emote client PC which is also
running the Trackit applica tion opens a TCP con nection to the server w hich enables the client to
take over control of the Trackit Mk3.

The server PC can be located locally to the patient, in the bedroom for example, and a wireless
Bluetooth link c onfigured to provide untethered communication with the Trackit. After any initial
setting up on the server, local c on tr ol can be relinquished and su bs equently acquired by a client
anywhere on th e network. In this scenario the server computer could be one of the miniature PC

Overview

Trackit Video prov ides an unobtrusive solution for the a m b ulatory monitoring of EEG with time syn ­chronised video. The Trackit Mk3 provides tim e s ync information to the video file to ens ure accu­racy down to the near est frame: essential to c or relate behaviou ral and physiologic al information.

Modes of operatio n

• Synchronized video acquisition and recording

• EEG recorded on the Trackit Mk3 with time sync information sent v ia cable or Bluetooth wire-

less to the video acq uisition PC

• EEG and video recorded on the PC with the Trackit Mk3 in ‘headbox’ mode

• As above with selective video recording v ia user intervention where eac h video segment is

time synchron ized to the corresponding EEG

• Synchronized video playback

Main features

• Support for a wide range of v ideo ca pture codecs including MPEG-4 and Windows Media
Video

• Selectable frame rates an d video compression

• Accuracy down to one frame when used with the sync file

• Automatic re-synchronization of the video when the Trackit Mk3 goes in and out of range

• User definable video file length to provide increased security and more manageable files for

copying over a n etwork. It also allows vid eo files with no interesting findings to be ea s ily de­leted thus redu c ing the amount of data.

• Time, date and patient ID stamp on the video

• Video zoom feature in playback

57

Trackit Mk3 User Manual

• Snapshot capture mode for a rec or d of the patient image

• Live monitoring of EEG and video on the host PC when recording in a m b ulatory mode

Video codecs

A video codec is a device or softw a r e th a t enables video compression and/or decompression for
digital video. This allows faster tra nsmission over co m p uter networks or more efficient storage on
computer disks. Video information that is not important for human perception is removed in order
to achieve very high compression ra tes while still keeping very good visual q uality.
There is a complex balance between the video quality, the quantity of the data needed to represent
it (also known a s the bit rate), the complexi ty of the encoding and decoding algorithms, robustness
to data losses and errors, ease of editing, random access, the state of the art of compression algo­rithm design, end-to-end dela y, and a number of other factors.

MPEG-4 codecs

MPEG-4 is a multimedia standard, delivering profes s ional-quality audio and video streams ov er a
wide range of bandwidths, from cell phone to broadband and beyond. MPEG-4 was defined by the
Moving Picture Experts Group (MPE G), the working group w ithin the International Organization for
Standardization (ISO) that specified the widely adopted MPEG-1 and MPEG-2. Hundreds of re­searchers around the world contributed to MPEG-4, which was finalized in 1998 an d bec a m e a n in­ternational sta ndard in 2000.
Microsoft was in volved in the early development of MPE G -4 but is no longer active ly supporting the
standard, choosing instead to concentrate on the Windows Media format. MPEG-4 can only be
played in Windows Media Player with a special MPEG-4 decoder pack.

Xvid

is a popular free/open source MPEG-4 Part 2 codec which works well with the Trackit video

application.

Windows Media Vi deo 9 series codecs

In 2006, the Soc iety of Motion Picture and Television Engineers (SMPTE) formally published the Fi­nal Specification for SMPTE 421M, als o known as VC-1. Formal s ta ndardization of VC-1 represents
the culmination of years of techn ic a l scrutiny by over 75 compa nies, leading to a c od ec that is well­documented, extremely stable, easily licensable, and accepted by the industry. Th e comprehensive
specification delivers high definition content across any medium and to any capable device.
Windows Media Pla yer as part of its installation, includes WMV codecs.

AVI

Audio Video Interle a ve is a multimedia c ontainer format which allows synchronous audio-with­video playback. The AVI file contains data which can been encoded by almost any codec, inc luding
Full Frame (uncompressed), Intel Real Time (Indeo), Cinepak, RealVideo and MPEG-4.

ASF

Windows Media Video files are in most circumstances encapsulated in the Advanced Systems For­mat (ASF) container format. The f ile e xtension .WMV typically d escribes ASF files that use Windows
Media Video codecs.

Appendix 5: Bluetooth Wireless

Introduction

Using a single plug-in Bluetooth interface m odule on the Trackit Mk3, wireless connections can be
established with it from any Bluetooth-enabled PC, Laptop or PDA. This allows the Trackit Mk3 to
be controlled or monitored remotely over a secure wireless link up to a range of a b out 100m or
greater (dependent on har dware and environmental factors ).

Bluetooth primer

It is not intended h e r e to provide a full intr oduction to Bluetooth technology, how it works and how
to use it. There is a huge amount of information elsewher e that is available for th is purpose. Nev­ertheless, a sh or t de s cription will be given to identify some of the common terms th a t will be used
later in the document.

The term "Bluetooth" refers to a worldwide standard for the wireles s exchange of data between two
devices.
In order to exch a nge data, two Bluetooth devices must establish a connection . Before a connection
is established, one device must req uest a connection w ith another. The second device acc epts ( or
rejects) the connection.
The originator of the request is known as the client. The device that accepts (or r ej ects) the re­quest is known as the server. Many Bluetooth devices can act as both client and server.
A client Bluetooth device runs a software program that requests a connection to another device as
part of its normal operation. For e xample, the program may request a connection to a remote com­puter, a printer, a modem or a Trackit Mk3.
Becoming a Blue tooth client norma lly requires an action by the device operator, such as an attempt
to browse a remote com p uter, print a file, d ia l out on a modem or connect to a Trackit Mk3.
Every Bluetooth device that provides a service must be prepar ed to respond to a c onnection re­quest. Bluetooth softw are is normally running in the background on the server, rea dy to respond to
connection requ ests.

Specification Summary

• The devices in a piconet share a common communication data channel. The channel has a

total capacity of 1 m eg a b it per second (Mbps). Headers and handshaking information con­sume about 20 percent of this capacity.

• In the United States and Europe, th e frequency range is 2,400 to 2,483.5 MH z, with 79 1-

MHz radio frequency (RF) channels.

• A data channel hops randomly 1, 600 times per second between the 79 RF channels.

• Bluetooth can tra nsmit up to 721 kilobits per s econd (Kbps) in on e dir e c tion, with 57.6

Kbps in the other. If the use calls for the s ame speed in both direct ions, a link with 432.6 ­Kbps capacity in each direction can be made.

• Each channel is divided into time slots 625 mic r oseconds long.

• A piconet has a master and up to seven slaves.

• Packets can be up to five time slots wide.

• Data in a packet can be up to 2,745 bits in len gth.

• There are currently two types of data transfer between devices: SCO (synchronous connec-

tion oriented for voice and audio) and ACL (asynchronous connectionless) .

• In a piconet, there can be up to three SCO links of 64,000 bits per second each.

• Masters can support u p to three SCO links with one, two or three slaves.

• Slots not reserved for SCO links can be us e d for ACL links.

• One master and slave can have a single ACL link.

• ACL is either point-to-point ( m a ster to one slave) or br oadcast to all the slaves.

• ACL slaves can only transmit when requested by the master.

• A Class 1 device has a maximum output pow er of 100mW (20dBm) and has a range of

about 100m.

61

Trackit Mk3 User Manual

• A Class 2 device has a maximum outpu t power of 2.5mW (4dBm) and has a range of a bou t

20m.

• A Class 3 device has a maximum outpu t pow er of 1mW (0dBm) and has a range of about

10m.

System overview

The system and its parts

Figure 46 Trackit Mk3 with Internal Blue t ooth Module

Internal Bluetooth

Trackit Mk3 has built-in Bluetooth capability which can be ordered as an option. When present
there is a small ‘β’ on the display as shown in Figure 4 on page 19. This inter nal Bluetooth can be
enabled by pressing the pushbutton 5 times within 3 seconds whereupon the display will change to
a ‘B’. Note that when enabled, the normal serial cable communication with the host PC b ecomes
inoperative. At any time the B luetooth can be disabled by again pr es s ing the pushbutton 5 times
within 3 seconds . This will restore the s e r ia l cable commun ic a tion.

The module is qualified against Blu etooth specification V1.1 or V2.0 (la te r m od ules) and it will com­municate with a ny similarly qualified Bluetooth device e ls e where. This means that the Bluetooth
host (client) can be any standard qu a lified Bluetooth periph e r a l device bought off-the-shelf. Life­lines does not supply the device at the host end and the User can make his own choic e from the
wide range availa b le. Note that to ach ie ve the maximum transmission range, this Bluetooth device
should be of the H igh Power (Class 1) type to m a tch the Trackit Module. Lower power devices
(Class 2 and Class 3) will still work, b ut the range will be less. The receiver sen sitiv ity should also
be as good as possible because this also helps to maximise the transmission range. Look for a sen­sitivity figur e of at least –80 dBm (for 0.1% B ER ) or better.

These standard qualified B luetooth devices are available as U SB converters, PC-card or CF-card
converters, S er ial Port converters a nd even built-in to PDA dev ices , Laptops and desktops. The
Trackit Mk3 will communicate with all these devices through the standard Trackit Setup or Wizard
Setup programs that have been enhanced to provide trans pa r ent Bluetooth functionality. T hese
programs will work over a direct connection, over a Bluetooth wireless connection or over a net­work or even over a combination of connec tions.

What you can do w ith a Trackit Bluetooth link:

• Connect wirelessly to any Track it within range equipped with a Bluetooth Module

• Control the Trackit wirelessly ( Acquire on/off, Ongoings on/off, Im p ed a nce Check on/off, Re-

cording on/off, Calibration on/of f etc.)

• Send setups to the Trackit wirelessly

• Review the Trackit status wirelessly (general system status as well as Trackit time, recording

time, battery level, disk level, SaO2 level, heartrate etc.)

• Monitor the Trackit Ongoing traces wirelessly

• Acquire wirelessly and record on a PC (this is using the Trackit as a wireless Headbox)

62

Trackit Mk3 User Manual

• Connect wirelessly as a second user (a Guest) and review Trackit status and also monitor Ongo-
ing traces, Imp.Check, Events etc.

• Mark an event over the wireless link

• Optionally configure the Trac kit to automatically record locally whenever the wireless lin k is lost

• Connect wirelessly and directly to s everal Trackits simultaneously f r om the same PC. These

Trackits are als o s imultaneously a vailable for Guest connections

Connection and use

The Trackit Setup and Tra ckit W iz a r d pr ogra m s have been enhanced to provide tra nsparent Blue­tooth support. A ll the functionality of the programs is available over a direct connection or a Blue­tooth connection . Note that the Tra c kit should be fitted w ith V2.10.x or later f ir mware.
Figure 47 below sh ows the new Trackit Control Panel with the ad ditional Bluetooth features.

Figure 47 The Trackit Control Pane l

The Port number selection drop-down lis t now supports a shor t d escription of the port. This can be
a direct hardwar e p or t ( e .g. Com 1) or any of the virtual serial por ts provided by Bluetooth (e.g.
Com 10). These Bluetooth ports are setup w ithin the Bluetooth a p plication running on the PC. The
connection is fir st established with the Trackit via a sear c h, a Comm. port number is assigned and
various encryption and pairing options defined. Th e Tr a c kit is always the serv er and pr ov ides the
serial port conn ection service to the P C acting as a client. T hereafter, the particular Trackit can b e
connected to by ref e r ence to its Comm. port number only – opening the port from the T rackit ap­plication automatically opens and establishes the Bluetooth link.

Figure 48 below sh ows a typical My Bluetooth Places view from the application on th e PC and
shows two available Trackit Bluetoo th connections. F or additional information about setting up con­nections, refer to your application doc umentation.

Trackit Mk3 User Manual

Figure 48 A typica l Bluetooth Plac es view

Once a Bluetooth connection is established, the Bluetooth icon is displayed on the Control Pan e l
and also against the port number. If the particular Track it is off or out of range or the P C Bluetooth
adapter is unplugged, the connection attempt will be unsu ccessful. If a connection already exists
with the particular Trackit from another PC (the MASTER), then the word “GU EST” appears next to
the Bluetooth icon. A GUEST has limited c ontrol functionality but can review most aspects of the
Trackit and its recording. If the MASTER disc onnects, then all G U ESTs are also disconnec ted . One
of these GUEST s can then, of course, a tte m pt reconnection as a ne w MASTER. This func tionality is
an example of the Bluetooth piconet feature (in serial por t terms it is sometim es referred to as
multi-drop in the same way th a t a har dware RS485 link can be multi-drop). In theory, there can be
7 devices in a piconet, although in practice this is very depen dent on data volume between the de­vices. Multi-drop is also s ometimes referred to as point-to-multi-point.
This piconet and m ulti-drop feature of Bluetooth offers v er y powerful and flex ible c onnection capa­bilities to the Tra c kit system. Not only can a single PC connect to any Trackit in r a nge, but another
PC (or perhaps PDA) can also connect simultaneously to th e same Trackit or any one of the other
Trackits. It is also possible to configure a Trackit Bluetoo th connection as a network server – in
which case a Trackit client can conn e c t to it anywhere on the n etwork (the fact that it is ultimately
a Bluetooth conn e c tion to the Track it is transparent to the c lie nt).

When the Track it a p plication has es ta b lis hed the Bluetooth c onnection, a connection quality moni­tor labelled “Com m s.Q” is displayed in the s tatus bar at the bott om of the main screen, as shown
in Figure 49.

64

Trackit Mk3 User Manual

Figure 49 Trackit Main Screen

This number given as a percen tage is a n approximate indication of th e a m ount of data received as
a ratio to that expec ted, calculated eve r y second. It is most likely to drop belo w 100% during the
transfer of ma ny ongoing traces. I t can also drop when either de vice is at the limit of th e tr ansmis­sion range or when either antenna is adversely obscured. It will be noticed that the Blu etooth
transmission w ill use its available bandwidth to try to “c a tch-up” after a drop in signal quality and
the indication can read m ore than 100% momentarily. A rea ding, therefore, of less than 100%
does not necessarily mean a permanent bad connection since data flow can increase shortly after­wards. A sustained low value over se veral seconds will cause the Trackit app lic ation to close the
connection. I f the Autoconnect fe a ture has been enabled in Options, the application will automati­cally attempt to reconnect to the designated Trackit ev e r y 10 seconds.

Note: Under certain circumstanc es the Bluetooth comm p or t is not identified by the software as a
Bluetooth port and the Bluetooth icon will not appear in Figure 47 The Track it Control Panel, when
connected. Th is can happen depending on which Bluetooth sta ck is installed and the version of
Windows. It is im p or ta nt that the software does identify Bluetooth virtual comm ports correctly
since various internal parameters a re optimised. See next section for a s olution to this problem.

the identification of which Track it is to b e connected to (and thereafter which Trackit is being con­trolled). It applies to the Trackit Bluetooth Module and if this is moved from one Trackit to anothe r ,
the connection f ollows the Module not the Trackit. Each Module has a unique name that can be re­peated here if desired, or som e oth er naming convention used. N ote th a t th er e m a y well be hard­ware ports, USB p or ts and Bluetooth ports – all of which can be us ed by the Trackit applicati on.

• Auto Tra cki t con nect. If ticked this will caus e the application to attempt to reconn ect to the
designated Trackit after a disconnect. The disconn ect can be loss of Blu etooth link or un­plugged cable etc. N ote that it is not a manual disconnect, which cancels the Autocon nect fea­ture. Autoconnect starts after the first manual conn ection.

• Autoupload. If ticked this will cause the applic a tion to automatically upload the Trac kit’s setup
immediately after a connection is established. It is on ly enabled if Auto Tr a ckit Connect is ena­bled.

• Save Event File. If ticked this will cause the application to a utomatically u ploa d the Trackit’s
event file immedia tely after a con nection is establish e d and save it in a tempora ry file called
TempEve1.tev in the defa ult application path. This file can be viewed or emailed out at a later
time with or without the Trackit conne c ted . It is only enabled if A uto Trackit Connect and
Autoupload are enabled.

• Port. This is the port number that the application u ses for its TCP networkin g c onnection. For
the client, this des ignates the local port to send data from. For the server, this is the local port
to listen on.

• Tracki t auto-record when Host comms. lost. If ticked the Trackit will autom a tically start re-
cording when the Host communication is lost if it has been in Headbox mode (Host PC record­ing). This featu re is most useful with a wireless Bluetooth connection, but it w ill work for any
type of connection. If there is already a file on the Trackit dis k, then the usua l ru les apply :

1. The Trackit will not overwrite a file less than 24 hours old

2. The Trackit will append new data to a file less than 24 hours old if the Patient N a me, ID,
recording setup a nd all other details are ide ntical to its cu r rent setup

3. The Trackit will overwrite in a ll other cases

Note that the Trackit will not automatically stop recordin g upon reconnection. This must be done
manually from the Host if required.

67

Trackit Mk3 User Manual

• Use File Length in stead of EDF Length. This a playback feature and if ticked, the file length
is used instead of the edf length pa r a meter em bedded in the edf header. Due to the fact that
the Trackit’s memory card can be removed at any time, there can be a partial 1s data block at
the end of the file a nd so the actual size m a y not be an exact multiple of 1s.

Bluetooth Options

• A llow Guest connection. If ticked this will allow the a pp lic ation to become a Bluetooth
GUEST. Before actual connection the application will l is te n on the connection to ascertain
whether a MAST ER is already in control of the designated Trackit. In these situation s, the new
application becomes a GUEST connection if allowed. Note that this option concern s the applica­tion only. Ther e are other options tha t c onfigure the Trac kit and the Bluetooth m od ule as re­gards GUEST connections (see below).

• S how Comm. errors. This allows any Comm. errors to be display ed on the main screen s tatus
bar below the Patien t ID. This applies to all connections, whether direct, USB or Bluetooth. It
can be useful when assessing signal quality.

Video

• A llow Video Resume mode. This allows Video synchronised recordings to be r es umed after
the PC has been powered-off.

• A nd a uto start video recording. This allows the video to automat ically start recording af­ter a Video Resume has occur r ed.

Bluetooth (Trackit) setup

• Initialise modul e at next switch on. If at any time the Bluetooth Module setup becomes cor­rupted, this option will instruct th e T rackit to initialise it with default settings when it is next
switched on. The usual method would be to use a direct connection for setting the opt ion (if

70

Trackit Mk3 User Manual

the Bluetooth lin k would not work), s witch-off the Trackit, c onnect the Bluetoot h Module to the
Trackit and switch-on. The Trackit will reme m be r its initialisati on task, will detect the Bluetooth
Module and initialise it with defa ult values (sufficient to enable it to work). Note that it can take
several seconds for the Trackit to do this – do not change a nything until the Trac kit is ready.
The Trackit will only do this initialisation once – even if pow er ed of f and on again, until in­structed again to do it. Also note that at switch-on, if the Trackit does not detect the Bluetooth
Module, the remembered instruction is cleared.
The situations whereby a Blu etoo th Module might become corrupted a re very rare, however
due to the complexity of Bluetooth an d the full access given to a ll the setup parameter s , it is
possible that inad vertent or inex pe r ienced operation may cause incorrect s ettings. It should
also be noted that it is possible to allow the s e tup of the Bluetooth Module to occur over a
Bluetooth connection (refer later) . This could allow unexpected connections to interfere with
the Module setup.

• Use low-power mode . Only use this option for the early external first generation Bluetooth
Module. If ticked this option instruc ts the Trackit to put the Bluetooth Module into a low-power
state after a period of no connection (the configurable tim e r is d escribed below) . This low
power state contr ibutes significantly to extending th e Trackit’s battery life whilst still of fering all
the desirable fea tures of Bluetooth . In this state the Module is still discoverable and connec ta ­ble, but upon con nection it must be tak e n out of the low-power state. Th e a pplication detects
whether the Module is in low-power state a nd if so instructs the Trackit to set the Module to
normal mode. To accomplish this, the Bluetooth connection must be dropped mom e ntarily and
then re-connected. The entire process is automatic and takes about 5 seconds. Refer to the Ap­pendix for details of the low-power mode power savings. Note th at when using the new G ener­ation Bluetooth Modules (OEMSPA332i and OBS433i) there is no benef it to using low power
mode, so the option should be left off. During the connection time, the applica tion displays the
following :

• Low-power mode time out. This option allows the se tting of how many m inutes of no connec-
tion must elapse before the low-power m ode comes into operation.

• A llow Guest connection. If ticked this option instructs the Trackit to accept more than on e
simultaneous Bluetooth connec tion. Note that there is a separate enable for the application
(described on page 67).

General

• A llow BU battery charge from main battery. Now that it is possible to con nect to the Trackit
wirelessly, it is n o longer possible in these situations to charge the Trackit’ s b a ckup battery
from the Isolator, as was previously p os sible with a direct wir ed c onnection. It is impor ta nt that
the backup battery is charged because it pr ovides power to the Trackit’s internal c loc k/calendar
chip and also prov id es p ower to enable the Tra ckit to continue recording for a short wh ile dur­ing main battery r ep la c e ment. This option, if ticked, enables the Trackit to use its main battery
for charging its backup battery. The Trackit only ever charges its backup battery once at
switch-on and only after a 10 min ute rest period (in ca s e the Trackit is switched on and off re­peatedly in quic k succession). Add itionally, the Trackit will only use power from its main bat­teries if they are within 75 – 100% of their capacity, i. e. fresh batteries. Furtherm ore, the
Trackit will only c harge its backup batte r y for a period of 10 minutes. All this means that the
backup battery will receive a 5% charge at every Trackit switch-on at the expense of a 0.5%
drop in main battery capacity (assuming a single alkaline battery – it will obviously be propor­tionately less of a reduction for more main batteries). U s ing this option it is pos sible to disable

71

Trackit Mk3 User Manual

this feature if a regular connection to the Isolator is made. Also note that it is pos s ible to man­ually initiate a backup ba tter y c harge sequence.

Trackit Default Options | Tab 4 (Bluetooth Module)

Tab 4 contains th e third set of Bluetooth options as shown in Figure 55 below.

Figure 55 Trackit Defaults Tab 4

CAUTION : Access is prov id ed here to the full set of Bluetooth configuration parameters in the

Module. Adjusting these settings can cause incorrect operation. Please contact your Trackit Service
Representative before adjusting these settings.

The setup of the Bluetooth Module itself is accomplished over the Bluetooth link currently estab­lished. This mea ns that no extra har dware is required to connect in some other way to the Module
– it remains conne c ted to the Trackit.

Clicking on the Setup button instru c ts the Trackit to enter
a special mode to enable the setup-over-Bluetooth func­tion. During this time the connection must be dropped
momentarily and then re-connected. The entire process is
automatic and takes about 5 seconds.

After the configuration process has finished, access is
provided to the main B luetooth Setup pane ls shown be­low.

Bluetooth Setup | Tab 1 (General)

The Bluetooth Setup screen is sh own in Figure 56 below. It should be noted that even though the
Trackit has put the Bluetooth Module into the special Setu p -over-Bluetooth mode, no changes are
allowed until a special comm a nd sequence has been sent to the module. This procedure guards
against casual browsers being able to adjust settings (there is much more in formation about secu­rity later on). Clicking on the Connect button sends the special command and also reads from the
Bluetooth Modu le all its current settings which are displayed in the various tab panels.
Clicking on the Read button causes a re-read of all the Module’s pa r a m eters .

72

Trackit Mk3 User Manual

Clicking on the Write button causes all values currently being displayed to be written across to the
Module which s tor es them in its non-vola tile memory.
Clicking on the Set defaults button loads defa ult values into all displayed settings ( these are not
sent to the Module until a Write occurs).
Clicking on the Disconnect button finishes the setup session and issues commands to disable
changes to the Mod ule setup and also to ta ke it out of Setup-over-Bluetooth m ode . The Module is
now ready for us e with the new settings.

Figure 56 Trackit D e faults | Blue t ooth S e tup Tab 1 (Gene ra l)

• L ocal Name. This allows the M od ule to be given a ‘frien d ly name’ (in a simila r wa y to a net­worked computer). This name is the one reported by other computers during a search or con­nection. If there are several Trackit Bluetooth devices on-site, it is important that each ha s a
unique name. As supplied, every Module will be uniquely na med a nd this will be in the form of
‘Trackit Blue x’ where x is numeric. D o not change the name unless there is a good reason to
do so.

• B luetooth Device Address. Every Bluetooth device is assigned a unique address (in a similar
way to the IP address of a network adapter). The address is read-only and cannot be changed.
The Module can be r eferred to from a remote d e vice by either its local name or in some situa­tions by its Bluetooth Device Addres s .

Discoverability

• None. If selected the Module cannot be discover ed by other devices during a search – it be­comes invisible.

• Limited. If selected the modu le becomes only partially discoverable.

• General. If selected the Module can be discovered by other devices.

• Connectable. If ticked the Module can be connected to by another device. Otherwise a con-

nection is not allowed. The application forces Connectab le.

• A ut hentication an d e n c ryption enabled. If ticked the remote device must k now th e Module’s
PIN code passkey to be able to conn ec t. The Module undergoes a ‘pairing’ pr ocedure with the
remote device. Additional ly in this mode, all data transf er s a r e encrypted using the same PIN
code as a passkey.

• PIN code. This is the code that must be known to the remote connec ting device to enable a
connection to be made. The code is en ter ed once only during the ‘pairing’ procedure on the
host (client). I t can be set here in the module to any numeric sequence. It is only used if Au-
thentication and e ncryption is enabled in the Module or the remote device requires authen­tication.

Figure 57 Trackit Defaults | Bl ue tooth Setup Tab 2 (Profile )

Wireless Multidrop

This section cov er s the multiple-conn ection capabilitie s of the Module. It is pos s ib le for several
Bluetooth devic es within range of each other to set up a ‘pic onet’ amongst themselves, whereby
each device can have connections to several other devices simultaneously. In this mode several re­mote devices can connect simultaneously to the same Tra ckit. All data transm itted by the Trackit is
transmitted to al l c onnected clients (the individual applications filter out the specific data of inter­est). For received d a ta , the Trackit receives all data transmitted by all clients (the Trackit ma intains
a separate data flow path for each client).
In Trackit terms , the first connection is the MASTER and it has full control capabilities. Subsequent
connections becom e GUESTs and they have limited control capa bilities. It is pos s ib le to individually
enable each clien t a p plication as to w hether it can become a Guest connection or n ot.
It should be noted that not all remote B luetooth devices handle multidrop/pic onet connections very
well and some will experien c e dr opped c on nections and loss of data. Refer to the Knowledge Base
for additional in formation.
It should be noted that within the B luetooth specification there is provision for such piconets to
themselves connect to other piconets – the combination being called a ‘scatternet’. In such a situa­tion, each picone t m ust designate a Ma s ter device with all the others in the picone t be ing Slaves. It
is the Masters in each piconet which maintain the scatternet. Such a complex top ology is beyond
the scope of this document but the brief de s c ription is given for completeness. It is the reason for
providing the Master role [or Master/Slave] optio n in the panel.

• Enabled. If ticked several remote devices can c onnect simultaneously to the same Trac kit. Oth­erwise multiple connections are dis a b led . Note that if ticked then the Master role [or Mas-
ter/Slave] should also b e ticked. If untic ked then the Master role [or Master/Slave] should
also be unticked.

• Master role [or Master/Slave]. In some of the more complex topologic al arrangements it is
sometimes necessary for a device to switch from being a Master to a Slave and vice-versa. In
the Trackit situation this parameter should have the sam e s e tting as that for the Enabled pa­rameter. If Enabled is ticked then Master role [or Master/Slave] should also be ticked. If
Enabled is unticked then Master role [or Master/Slave] should also be unticked.

1. The list of adapter hardware used by Lifelines so far is as follows :

• Belkin Bluetooth USB adapter F8T001

• Ezurio/TDK Bluetooth USB adapter “go blue”

• Newlink Bluetooth USB adapter US BBTC1A-N-CDL

• Anycom Bluetooth Compact Flash Card CF-2001

• Bluemonkey Bluetooth Compact F la s h Card BlueCF

• Linksys USBBT100

reason. This e ff e c t can be tested by conn ecting to the Trackit and switching ongoings on. This
produces a lot of predominantly one-way traffic. The connection should never be dropped. This
effect has been found u s ing the Belkin F8T001 Bluetooth USB A da pter. The problem has been
fixed by installing a later version of the WidcommSdk.d ll in the system32 folde r . Version

1.4.1.6 or later seems to fi x the problem.

3. It has been found that some 3
Trackit Bluetooth is set up for multi-dro p s upport, even when there is only one connection. This
effect has been found u s ing the Belkin F8T001. The solution is to either dis a ble multi-drop on
the Trackit Blu e tooth Module or to make the Belkin device Un discoverable AND Unconnectable.
This effect has not been f oun d on oth er devices so far – the TDK and Newlink adapters a re ok.

4. It has been found that some 3
connections. T his has been foun d on the Belkin F8T001 whic h only seems to support a s ingle
connection. The TDK adapter does all ow several simulta neous connections. In any event, you
should expect data tr a nsfers to slow whe n using several simultaneous connections.

5. Sometimes it may appear that your Bluetooth connections in My Bluetooth Places or Entire
Bluetooth Nei ghbourhood seem to be forgotten when the Bluetooth adapter is unplugged or
after a power-off. Also, you may find that you cannot allocate a Comm Port to your connection
(each Track it Blue x connection needs its own Comm Port). The reason for this is that you have
set up a temporary c onnection in Entire Bluetooth Neighbourhood rather than a shortcut
reference in My Bluetooth Places. Here, connection definitions are perma nent and you can
allocate Comm Ports at will. When s e tting up a Trackit connec tion for the first time, you should
use the proper Wizard or other m ethod as provided by the adapter ma nufacturer. If you find
that you can alloca te a Comm Port to a conne c tion, but there are not e nough virtual Comm
Ports to select from in the list, check in Device Manager that there are enough por ts c alled
“Bluetooth Communications Port (COM x)” for your use. If not, either use your adapter applica­tion to add some more or use the Windows Add/Remove Hardware Wizard to add “Ports ( COM
& LPT)” followed by WIDCOMM.

9 Choose Recording from the S etup Menu, or click on the spanner icon on the toolbar, to create

or select the recording mon tage. Under the Recording Channels tab, select the size of the card

in use to see the available recor ding time with the montage selecte d.
Once selected, the montage appears on the left of the trace window.
10 In the Trackit control panel dialog select the Set Recording bu tton and click on Send Setup.

This downloads the recording setup to the Trackit recorder in preparation for a recording.
11 View the EEG prior to r ec ording by selecting the Ongoings On icon from the Trackit toolbar. You

can only view as many traces as can be transferred across the serial link at any one time – 12

or 16 channels depending on the sampling rate used for the M k 1 an d up to 40 for the Mk2.
T o look at the traces that are not displayed, click the up and down a r r ow keys on the right

hand side of the toolbar.
12 Perform an impedance check. If this is done after a recording has started,

an impedance check ev ent will be recorded. After viewing the impeda nce values, cancel the im-

pedance check.
13 Go back to the Set Rec or d ing dialog that shou ld still be open (activated from the Trac kit Control

Panel), and c lic k on the Start button. Th e Trackit is now recordin g data to card.
14 Disconnect the RJ45 cable to the Trackit. Put the recorder in the pouch with sh oulder strap pro-

vided.

At the end of the ambula t o ry recording

15 Connect the Trackit once again to the RJ 4 5 c able, and for Mk2 Trackit make sure that the

RJ45/D9 Converter is power ed a nd connected to the PC.
16 Restart the Trackit software. Open the Trackit Control P a nel as previously described. Select the

Set Recording button agai n.
17 Click on the Recor d O ff button. The recor ding now stops.
18 Detach the Trac kit. Open the rear door with the tool provided . Remove the flash c ard.

COM port problems with Bluetooth communication to Trackit Mk3

The COM port is available but is being used by another application.

This could well be th e c ase if an application s uch Microsoft Activ e Synch is installed and polling the
COM port for a Windows CE device. Make sure Connection Mode for Active Synch is s et to Only
When Device is C onnected, and not to Continuous.

Make sure other applications such as virus protection software and personal firewalls (ZoneAlarm)
are not accessin g the COM port while a connection to Trackit is b eing made.

Problems starting the recording

The setup has not been sent correctly

Under Trackit S tatus, in the Control P a nel, check that Acq uire Ready shows Yes . If it is not ready,
acquisition ca nnot begin. This could be caused by incomplete tr a nsmission of th e Trackit setup. Tr y
to adjust the trans mission delay for serial communication in the Trackit software as described
above.

An incorrect setup has been sent

If an incompatible setup has been sen t to the Trackit the mess a g e; “unable to comply” will indicate
that. The usual cause for this is if a T36 or T24P setup has been sent to a Trackit 24: the pres ence
of poly channels resu ltin g in the setup being rejected. If an incorrect setup has been sent, the
Trackit Control P anel will show ‘Ac quire Ready: No’.

The card is not formatted correctly

If the card is not formatted with a correct 16-bit FAT, a recording cannot commence. Format the
flash card usin g the inbuilt Trackit f ormat utility under Ge t Card Info. See ‘Get Card Info’, in

5.5 Advanced Settings.

Caution: do not attempt to do a low-lev e l format, or do a standard format using a SCSI or
USB card reader.

The card is corrupted

Disk corruption can be caused when a flash card is removed from Trackit or the Card reader while
data is being written or accessed.

Trackit: always stop a recording, or if hot swapping wait for the write LED to go out, b efore remov­ing the card.

Card reader: make sure the dev ic e is s to pped, in Card Services, before r emoving the Card. This is
especially important in Win2000 systems using a USB ca r d r eader, where the activity L ED stays on
for several seconds after deleting an old file. If the card is removed when this LED is on, the card will
be corrupted and a reformat will be necessary . Always stop and eject the card using the icon in the
Windows system tray before physic a lly ejecting it.

The card is not inserted correctly

If the flash ca rd is not pushed in far enou g h, the card will not engage th e p ins on the card reader.
‘No CF card present’, in the Status section of the Tr a ckit Control Panel, will evidence this.

File review problems

The card is not formatted in FAT16

When a recording is made on a car d formatted in FAT32 it will appear t o be severely truncated and
most probably unreadable. If you know a recording has a duration of >24 hours bu t it only shows
up as several minutes in review, the m ost likely cause is that the card is not form atted in FAT16.

Field strength from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios,
amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the
electromagnetic environment due to fixed RF transmitters , an el ectromagnetic site survey should b e consi dered. If the meas­ured field strength in the location in which the Trackit is used exceeds t h e applicable RF compliance level above, t h e Tr ackit
should be observed to verify no rmal o peration. If abnormal performance i s observed, additional measures m ay be nec ess a ry,
such as re-orienting or relocating the Trackit.
