1.2 Dive computer
UWATEC dive computers of the Aladin family and compatible
instruments save the logbook data of your dives in an internal
logbook. More dives are saved than are displayed in the
logbook of the instrument. In addition, the current dives are
stored in detail with a dive profile in 20-seconds increments.
When the profile memory is full, the oldest profile data are
overwritten. Please consult your dive computer operating
manual for detail edinformation he logbook and profile memories of your instrument.

data of the last 37 dives. The most current dives up to a maximum of 200 dive minutes (e.g.
4 dives each of 50 minutes’ duration) are saved in detail with a dive profile in 20-seconds
increments. Air-integrated and Nitrox dive computers also save information about gas mixture,
CNS activity and air consumption.
1.3 Memo Mouse
Memo Mouse is the link (interface) between dive computer and personal computer, and its
integrated software allows the data transfer with DataTrak and DataTalk.
But Memo Mouse means a lot more
Memo Mouse is a temporal memory for your
dive data which stores detailed data and dive
profiles of up to 66 one hourdives. This allows
you to store your dive data even if you have
no access to your personal computer over a
longer period of time. This is especially important for dive holidays.
• The stored data are transferred from Memo Mouse to your personal computer.
• Memo Mouse recognizes all compatible dive computers. It also discriminates between
individual dive computers and transfers this information to your logbook.
• You can store data of more than one dive computer in the same Memo Mouse. In order to
transfer the contents of the memory from the Memo Mouse to your personal computer a
dive computer must be connected. Memo Mouse only transfers the data of the connected
dive computer.

DataTrak for Windows replaces your logbook and offers additional interesting possibilities.
Page 33 With DataTrak you import dives from the dive computer and from a Memo Mouse
Page 37 Manually enter in the logbook dives which are not stored in your dive computer.
Page 30 You can keep more than one logbook with DataTrak. Each logbook is saved under a name
of its own.
Page 40 The dives are always listed correctly in respect of date and time.
Page 38 You can select your dives in respect of certain criteria.
Page 37 DataTrak keeps statistics of your dives.
Page 41 Your dives are represented graphically in the form of dive profiles if they are imported from
the dive computer regularly. In addition, the display indications, physiological data and tissue
data of the whole dive are displayed.
Page 48 These instruments of analysis are especially suited for training purposes and for the improve-
ment of the personal diving technique, since the exact reconstruction of dives allows conclusions
about the individual actions in specific situations. DataTrak also offers an important and helpful
means for the investigation of diving incidents.
Page 31 Have of surveys dive data and dive profiles printed out in a very simple manner.
Page 10 – DataTrak
1.5 DataTalk for Windows
DataTalk is a service programme allowing you to adjustthe basic settings of yourdive computer
to your personal needs. The adjustable settings depend on the type of dive computer you use.
Air-integrated computers
also have adjustable
reserve pressure settings
and sensitivity control for
the overexertion warning.
Nitrox computers also
have an adjustable maxi-
mum oxygen partial
pressure value.
1.6 Older versions of DataTrak and Memo Mouse
What’s new?
1.6.1
DataTrak for Windows nowoffers, as opposed to the previous DOS versions, all the advantages
of Windows applications. In addition to the considerably simpler operation and the windows
style, there are also set-up advantages:
8 The programme ought to recognise automatically the serial port where the Memo Mouse is
connected. There is no need to input settings concerning the port. Only connect the Memo
Mouse to an available port, and on you go!
8 Any kind of printer supported by Windows prints out logbook data.
8 Compared to previous versions of DataTrak, additional functions have been installed: Dives
of other DataTrak logbooks may be imported. You also choose and export dives from your
logbooks.
Survey
All dive computers can be switched from the
display of metric units (metre/bar) to imperial
units (feet/psi). All instruments that have acoustic warnings as well as visual warnings can
have the acoustic warnings switched off.
Page 11 – DataTrak
Survey
8 You can select several dives in the dive list. Printing, export of dives and statistics are then
limited to this selection.
1.6.2
Taking over logbooks from older versions of DataTrak
Logbooks which were written in DataTrak for DOS can be imported into DataTrak for Windows.
1.6.3
Older Memo Mouse versions
The newly developed Memo Mouse and the software package DataTrak/DataTalkfor Windows
are an integrated package.
No data can be transferred to DataTrak for Windows with the previous DOS version of Memo
s
Mouse. Equally, the DOS versions of DataTrak/DataTalk cannot process data from the new
Memo Mouse.

5 Managing Dives and Logbooks
5.1 Menu Logbook
The logbook programme DataTrak allows you to store dives in one or several logbooks. This
means that several people can manage their dives with the same programme, dive clubs can
record and manage the dives of all members, dive schools can record all instructional dives
of the trainees, or you can create separate logbooks for different types of dives or per year.
This chapter tells you,
8 how to open, create, and store logbooks;
8 how to export dives from one logbook and to reimport them into other logbooks (p. 30);
8 how to number your dives (p. 31);
8 how to print out your dive data in a great variety of ways (s. 31).

5.2 Menu Dives
Dives are either transferred from the dive computer or the Memo
Mouse to the personal computer, or entered manually.
This chapter tells you …
8 how to import data from the dive computer,
8 how to enter, delete, complete or alter dives manually,
8 how to select dives according to certain criteria,
8 how DataTrak evaluates your dives statistically.
Also how to use the supplied example file if you are new to DataTrak.
5.2.1
Transferring data from dive computer or from Memo Mouse
In order to receive dive data from a dive computer or from Memo Mouse proceed as follows:
Before transferring data, make sure that the time and date of your personal computer are
correct! This is important since time and date of the dives are calculated by DataTrak using
s
the system time of your PC.
Wrong system time and date have the consequence that time and date of your dive are entered
wrongly. Connect the line to a free serial port of your PC and establish the connection between
Memo Mouse and dive computer (see p. 15).
Managing Dives and Logbooks
Page 33 – DataTrak
Managing Dives and Logbooks
ä In the DataTrak software, open the logbook to which you want to transfer the dive data.
ä Select function Transfer. The programme advises you that it is ready to receive data, and the
timer starts counting backwards from 60 seconds. The data transfer has to be started within
this period of time.
Check or alter the transfer options (see Tips and tricks, p. 57).
Only new dive Only dives are transferred which have been carried out after the last logbook entry (date and
time).
All dives All the dives of the connected dive computer and the dives of this dive computer stored in the
Memo Mouse are transferred.
ä Activate the logbook mode of the dive computer.
This effects that the data of the connected dive computer and the dives of this computer stored
in the Memo Mouse are transferred to your DataTrak logbook in the correct order.
If your logbook is still empty you will be asked for the initial number (number of the first dive)
+
after the data transfer so that you can continue with your personal current dive number.
Each dive is allocated a continuous number in the logbook. You will find these numbers in the
list of dives on the left hand side of the screen. The dives are ordered chronologically according
to date and time.

5.2.2
Insert dives (manual input)
Managing Dives and Logbooks
DataTrak creates a graphical representation of dives which are marked beside the number
and shows further data of the dive (p. 41ff., Profiles/Dive analysis). These data are only
available for a limited number of dives in the dive computer (see operating manual of your
dive computer). If the profile memory of your dive computer is full, the profile information of
older dives is deleted automatically. Therefore, you should transfer your dives regularly from
the dive computer to your DataTrak logbook or to the Memo Mouse.
After importing data, complete the entries with the information not to be imported by the dive
computer (dive site, weather, type of dive, activity, etc.). Use function Edit for these entries
(p. 37). The statistical functions of DataTrak only make sense with complete dive data.
When using dive computers with integrated air information, the size of the tank is especially
important, since the air consumption is only be calculated if this information is available.
If your dive computer is in the SOS mode, you can still transfer the data to your personal
computer. Proceed in the same manner as described above. Only the activation of the logbook
is not applicable (the dive computer is blocked). The data are automatically transferred within
1 minute.
Select function Insert if you want to manually add a dive to a logbook, without using the
DataTrak transfer system.
Page 35 – DataTrak
Managing Dives and Logbooks
DataTrak opens an empty data sheet where you enter your dive data. The cursor is placed in
the field Date where the current date and time of the system are indicated. You can immediately
start with your entry. All the entering positions may be edited. Enter the dive date completely
and confirm your entry by OK. DataTrak inserts the new dive, according to date and time, in
the appropriate position in your logbook. If necessary, more recent dives are renumbered
automatically.
5.2.3
Delete dives
If you want to delete one or several dives from your logbook, proceed as follows:
ä Mark the dive or dives you want to delete from your logbook.
ä Select function Delete or press key [Delete].
DataTrak asks you if you really want to delete the dive.
NO closes the dialogue box without deleting the dive.
If you choose YES, the dive is deleted.
Deleting dives means definitive deleting of all data (incl. dive profile). Restoring is only possible
by reimporting the data from the dive computer if they are still stored in the logbook memory
s
of the dive computer or the Memo Mouse (the dive computer logbook saves more dives than
those which can be called up in its display).
In order to reimport data older than the last (most recent) dive, activate the option ALL DIVES
in the dialogue box Import dives. If you now import data from the dive computer, all the dives
are inserted which are no longer (or not yet) stored in the logbook.

Managing Dives and Logbooks
This function allows you to alter, add to and remove information. Select the dive you wish to
edit from the list of dives. Select Edit or doubleclick on the dive number in the list. Enter the
alterations in the respective fields. To save the alterations press key OK; if the alterations are
not to be saved, leave the entry box with Cancel.
Entries imported by the dive computer automatically are represented in grey and cannot be
altered.
s
If you have imported your data from the dive computer you will use the function Edit frequently,
since you ought to make additional entries to all the imported dives.
s
Especially with dive computers with integrated air information the size of the tank must always
be entered to allow the calculation of air consumption.
DataTrak gives you the opportunity to keep statistics about various criteria of your dives.
ä Select function Statistics.
The screen displays the statistics of the dives of the current logbook. The evaluation shows in
absolute figures and in percent:
• number of dives (=100%)
• number of repetitive dives
• number of dives in depth ranges (10-m increments)

• number of dives for each type of dive
• number of dives for each type of activity
• total dive time of all dives
• average dive time (average dive time of a
dive).
If you have selected a certain number of dives
manually or with the function Select, the statistics only refers to these dives!
The last line of the statistics window gives you
the opportunity to choose between the statistics

Selecting dives
When entering divedata in the logbook you canselect various predetermined criteria to classify
your dives. Here, you use these criteria to mark and select certain dives of the open logbook.
ä Choose the function Select.
ä Choose the criteria on which you want to select the dives.
Page 38 – DataTrak
Managing Dives and Logbooks
Date If you want to select dives which were made during a certain time span, enter the dates of
beginning and end of the desired period. If you make no alteration here, the whole time span
of the dates of all dives of this logbook is considered.
Depth range If you want to select dives of a certain depth zone, enter the desired depth zone (e.g. 0–20 m,
in order to display dives down to 20 m only).
Dive type When entering dives, you can classify dives into
types according to certain criteria. Click on the
hand icon on the right of the entering line and
select a type of dive.
The present entry selects no-stop dives in the
sea.
Activities On entering dives you can allocate them cer-
tain activities. For example, youonly have photo dives displayed by selecting this criterion
(procedure as with dive type).
ä If you have entered all selection criteria press
OK.
In the dive list, all the dives conforming to the desired criteria are marked.

The selection of dives has an influence on the functions Print, Export, Statistics, Delete and
Adjust local time.
Page 39 – DataTrak
Managing Dives and Logbooks
5.2.7 Adjust local time
Date and time of a dive are calculated and entered basing on the system time of your personal
computer when importing the dive to the PC. If you want to import dives of places with another
time zone than the one of the system time of your PC you have to make up for the time
difference in order to get the correct time in your dive data.
Example If you have imported the dives of a place with a time shift of +4 hours, proceed as follows
after importing the dives from your dive computer:
ä Select or mark the dives the time of which is to be altered.
ä Select the function Adjust local time.
ä Enter the difference of time (04:00) and the sign for the
direction of the shift (+).
ä Press OK.
The conversion of dive time and date for the selected dives is carried out automatically.
Before importing data, make sure that the system time of your PC is correct to assure the
correct calculation of dive time and date.

6 Profiles / Dive Analysis
DataTrak representsyour dives graphically as dive profiles if the dive data have been transferred
from the dive computer regularly. If you value the dive profiles and the multiple possibilities
of analysis, carry out the data transfer frequently enough to assure that the data are available
for the graphical representation (see operating manual of your Aladin dive computer). You
will recognise dives with dive profiles by the marks behind the dive number in the list of dives.
In case you do not have the possibility to directly input data into DataTrak for a longer period
+
of time (e.g. diving holiday), you should have your Memo Mouse with you to store the dive
data with all the relevant information for the graphical representation of up to 66 hours of
diving.
The graphics window is called up by clicking on the icon Profile. You can alternate between
+
graphics window and data window with keys [Ctrl] and [Tab] (tabulator) quickly.
The graphical representation and informations vary depending on the dive computer used.

Special cases
The 20-seconds grid may lead to contradictory indications in certain cases. You will find an
example in the supplied logbook file EXAMPLE.LOG (dive no. 1489).
At dive time of 7 minutes an ascent alarm is indicated although the profile shows a descending
course.
Explanation: The excess ascent rate was detected
within the 20-seconds increment between 7 min
and 7 min 20 s (the broken line shows the actual
course of the dive). Within the same interval, the
ascent had been stopped and a fast descent below
maximum depth of the preceding interval started.
The alarm given by the Aladin dive computer appears in connection with the descending course of
the profile.

6.3.2 Example of a dive
With the example dive (No.
1508 from the example file EXAMPLE.LOG) from Lake Zurich
(Küsnacht) we will illustrate the
analysis of dives. Minimum water temperature during the dive
was 6°C, average air consumption was 13.5 l/min. Maximum
depth of 40.8 m was reached
after 14 minutes, total dive time
was approximately ½ hour.

1 Immediately after starting the
descent, the tissues start saturating due to the rising pressure (the bars are red).
2 During the descent, the absolute gas saturation rises slowly. Due to the higher pressure more
nitrogen is dissolved in the tissues. In a parallel effect, the tolerated nitrogen pressure rises
quickly. Since the height of the bar represents the relation of absolute to tolerated saturation,
the height of the bar decreases.
3 After about a depth of 14 m, no-stop time drops below 99 minutes and is only 6 minutes at
the deepest point of the dive.
Profiles / Dive Analysis
4 After 16 minutes, the cooling
of the skin starts to show effects – increasing activity and
the indicated out-of-breath
alarm may be connected with
it. Current air consumption rises to 25 l/min.
5 Due to the heightened brea-
thing rate, RBT decreases
quickly to zero. At this moment, the diver is warned by
an acoustic and optical signal
about the used up RBT. The
diver reacts correctly and relaxes. The RBT alarm stops
(RBT rises above zero) although dive depth was reduced only little.
6 The diver now heeds the RBT and diminishes dive depth.
7 Tissue saturation rises continuously.
8 The diver does not react to the attention message that no-stop time is running out. The Aladin
dive computer switches into decompression calculation.
9 The diver has started his ascent. Already from a depth of approximately 30 m, the first tissue
starts desaturation – however, the height of the bar increases, since nitrogen tolerance drops
faster than the absolute nitrogen saturation due to decreasing ambient pressure (see also
point 2).

As a result the decompression time rises slightly from 3 to 4 minutes. The Aladin dive computer
gives the appropriate alarm.

Profiles / Dive Analysis
3 Problems apparently remain even at the prescribed decompression stop. The diver ascends
to the surface for 1 minute after a brief stop. The Aladin dive computer warns because of the
ignored decompression stop.
4 Due to the ignored decompression stop there is an increase of microbubbles.
5 The tissues of the central nervous system (CNS) reach or exceed the tolerated saturation values
(purple bars).
6 The decompression stop switches from 3 to 6 m, and the total time of ascent increases to 14
minutes.
7 After 30 and after 33 minutes alarms for ignoring the decompression stop appear. However,
they are not represented in the dive profile. This is a consequence of the registration increments
of 20 seconds explained in detail on p. 47.

The examples show that two dive buddies may easily get considerably differing decompression

prescriptions on the same dive. If the buddy of our diver in the second example has interrupted
the very fast ascent in due time, he will not have exceeded the no-stop time and will have to
observe the decompression stops of his buddy only as a companion.
Both examples show the direct effects of the divers’ actions on the decompression prescription.
The profile does not tell us about the effects on possible dives in the future. The divers in our

examples will notice a substantial extension of the no-fly time and a massive shortening of the
no-stop times for repetitive dives.

7 Tips and Tricks
Data for the statistics
The function Statistics (menu Logbook) can only provide sensible data if the necessary criteria
are consistently entered for all the dives. If the information for individual dives is missing, the
statistics will be incomplete!
Memory for holidays
If it is important for you to have saved all your dives with profiles, you have to transfer them
regularly to your PC. In order to have your holiday dives available with all their information,
the Memo Mouse must travel with you. The Memo Mouse stores up to 66 hours of dives with
all the necessary profile data.
Benefit of the dive profiles
The dive profile is an excellent analytical instrument for the tuition of beginners and advanced
divers to explain the conduct of the diver and the effects of the dive on his body. This requires
the data being transferred regularly from the dive computer to the DataTrak logbook or to
the Memo Mouse.
Import all / only more recent dives
Before the data transfer you can choose the options “import all dives” or “import only newer
dives” in the dialogue box Import dives. Normally, if you regularly transfer your dive data to
your PC you only need the option “newer ones”. Only those dives are imported which were
carried out after the latest logbook entry (date and time).
Tips and Tricks
Page 57 – DataTrak
Tips and Tricks
You need the option “all” if:
8 you want to import dives into a DataTrak logbook
already containing more recent dives (e.g. if more
recent dives were entered manually or if you want
to import data from a second dive computer).
8 you have deleted dives from your DataTrak logbook
and want to import them again (this is only possible
as long as the dives are still stored in the logbook
of the dive computer or in the Memo Mouse).
If older dives are inserted later on, the dive numbers
of the more recent dives are adapted automatically.

on the icon DataTalk (Windows 3.1x) or a single click (Windows 95).
9.1.1
Options
Language Choose the language for working with DataTalk
here, if you want to alter the setting defined in the
set-up procedure. This language option has nothing
to do with the settings of the dive computer.
Ports The setting AUTO should normally be kept. It should
only be altered if there are difficulties with other
hardware components also connected to serial ports.
9.2 Operation
DataTalk is basically operated according to the following scheme:
1. reading the current settings of your dive computer.
2. checking and adjusting the settings.
3. writing (transferring) the new settings to the dive computer.
9.2.1
Read
The reading of data from the dive computer is carried out in the same manner as when
transferring data to the DataTrak logbook:
DataTalk
Page 61 – DataTrak

ä Connect the cable to a free serial port of your PC and establish the connections with Memo
Mouse and dive computer (see p. 15).
ä Start DataTalk.
ä Select the function Read.
The programme indicates readiness for importing
data, and the timer starts counting down from 60
seconds. The data transfer has to be started within
this time span.
ä Switch your dive computer into logbook mode. Then
enter the logbook.
After activating the logbook, the data of the settings
are transferred from the dive computer to DataTalk.
The alterable settings are displayed in the DataTalk
window. Now, adjust the settings to your needs.
9.2.2
Write
Page 62 – DataTrak
If you have adjusted the settings, these have to be transmitted back to the dive computer:
9.3 Wake up
ä Select the function Write. The programme indicates readiness for transferring data.
Check the correct seat of all connections before starting the data transfer. Faulty transfer may
lock up your dive computer (Wake up).
s
ä If the dive computer is still displaying a logbook dive then exit from its logbook. Then reenter
the logbook mode and enter the logbook.
After activating the logbook, the data of the settings are transferred from DataTalk to your
dive computer.
If a transmission error occurs during the data transfer to your dive computer (e.g. if one of
the plugs is removed or disconnected), the dive computer may get stuck in the set-up mode
and no longer be operable.
In this case, proceed as follows:
ä Remove the reason of the error at once (reconnect plug).
ä Activate the function Wake up as quickly as possible. This ends the set-up mode. Your dive
computer can be operated again.

9.4.2 For all dive computers with acoustic messages
The acoustic signals attached to attention messages can be suppressed (see operating manual
of your dive computer). This does not affect the optical display. Acoustic alarms and their
optical displays cannot be suppressed.
9.4.3
For dive computers with air-pressure information
Remaining pressure The standardsetting of dive computers like Aladinis at the surfacesuch that a dive is terminated
with a remaining pressure of 40 bar. This safety pressure can be altered between 30–100 bar.
A minimum safety pressure of 30 bar is advisable in any case. In addition, pressure should
not be lower than 30 bar because of the formation of condensation liquid in the diving
s
equipment.
Sensitivity of the out-of-breath alarm
If you find your Aladin Air X gives an out-of-breath alarm too frequently, you may adjust the
sensitivity to your needs. An average sensitivity is set as a standard. First alter the sensitivity
on large scale (3 steps). On your next dive, you test the alteration and adjust the setting more
finely if necessary.
9.4.4
For Nitrox dive computers
Partial pressure Maximum partial pressure of oxygen can be adjusted of oxygen between 1.20 and 1.95 bar.
Standard value is 1.5 bar. ppO
max
of more than 1.6 bar should not be set for safety reasons.
