1: DSTmilli with owner's information text
Easy to use
DSTmilli is supplied with a supporting software
for Windows, and an upload box that is connected to a PC computer.All
communications and data transfer is wireless via the upload box.Simply
insert the DST into the upload box, and communication can be established
with the software.There is no need
for opening the DST, and the logger can be reused as long as battery lasts.Before
use of the DST, the user sets the sampling interval and starting time.After
recapture of DST, the data is retrieved to a PC computer, using upload
box and software from Star-Oddi.
Research
applications
DSTmilli is specially designed for tagging fish for analysing fish migration,
distribution, feeding behavior, vertical and horizontal movements.
DSTmilli can be implanted into the fish or fastened externally. DSTmilli
is ideal for research on other marine animals as well. The recaptured
DSTs provide valuable information on the behavioral patterns of the tagged
animal. For recapture purposes, customers can define their own text
on the housings.
DSTmilli can also be placed as a stand-alone logger for sampling in underwater
environments. DSTmilli
can for example be utilised in research projects within the fields of fisheries
research, marine biology, oceanography, zoology, limnology and ecology.

Upload box For communicating with the DSTmilli, a special upload box from Star-Oddi is supplied. The recorder is inserted into the hole in the upload box. The spherical end should face down. The recorder is twisted until the green light is on. Communication can be established using the SeaStar software and set in Measurement Mode. Even though the battery is dead, the user can always retrieve data because the recorder is fed with power from the PC computer through the upload box. . |

SeaStar - Graphic supporting software for Microsoft
Windows
The SeaStar
software allows the user to define the start time of recordings (year/month/date,
/hour/min.). Thus it is possible to save data memory until the recorder
is placed at the measuring site. This feature is also convenient
when several recorders are required to start recording at the same time.
The user also defines the sampling interval, which can be from 1 second
to few hours. The user has the option to define more than one sampling
interval for memory increase efficiency. Up to six different sampling
intervals can be defined. The user also defines number of measurements
to be taken at each interval. The intervals recycle until memory
is full. The DSTmilli automatically gets the clock from the PC computer
once connection is established.
The SeaStar
software retrieves the accumulated data and processes it in graphs and
tabular form. Maximum, minimum and mean temperatures are found.
The data can be exported to other data processing software packages.
Charts can saved as bitmap (bmp) or Windows Metafile (wmf) files.

Housing's capabilities
The white housing is made of bio-compatible material, not endangering the
health of the tagged animal.
The white housing has one attachment hole. For a two point attachment
on fish, Star-Oddi provides a two
point stainless steel wire fastener.
The housing insures excellent response time. The temperature sensor
is mounted directly on the inner side
of the housing.
The DSTmilli is also available in transparent housing, which is made of
more lightweight material. The
transparent housing might be useful for the smaller animals/species.
