Barometer opening
of the Diver-DXT will automatically synchronize once a day with the clock of the attached Diver datalogger. After
activation the radio module is awake during the day from 7:00 AM until 23:00 PM, waking up every 14 seconds.
During the night from 23:00 PM to 7:00 AM the radio is asleep and only wakes up once every 5 minutes. The radio
can’t be deactivated (turned off) by the user.
Furthermore, the water-resistant housing contains a datalogger for recording barometric pressure and
temperature. The sampling frequency of the barometric datalogger is fixed at once per hour. The Diver-DXT will also
function without starting the barometric datalogger.
The Diver-DXT contains an internal battery (battery lifetime 5 years under normal conditions). The battery of the
Diver-DXT can be replaced by the supplier.
The Diver-DXT is not meant to be used under water. The radio performance will decrease when the unit is covered
or surrounded by water. However, sometimes it is difficult to avoid flooding conditions. Therefore the Diver-DXT has
been developed to withstand this situation for a limited time. For more information about Diver-DXT specifications,
see Appendix III.
3.4. Diver-Gate(M)
The portable Diver-Gate(M) provides the communication between the Diver-DXT and a mobile device via a radio
and Bluetooth connection. The Diver-Gate(M) contains a short-range radio module to communicate with the Diver-
DXT through the unlicensed industrial, scientific and medical (ISM) radio band at a frequency of 2.405 GHz. The
unit also contains a Bluetooth radio for wireless communication with a mobile device (PDA, smartphone or tablet).
Furthermore the Diver-Gate(M) can be connected through a USB cable to communicate with a PC or laptop.
To communicate with the Diver-DXT the Diver-Gate(M) is carried into the field to a position within radio range of the
Diver-DXT. Through the software on the mobile device or PC the Diver-Gate(M) can be requested to start scanning
for nearby Diver-DXT’s. As soon as a connection is set-up between the Diver-DXT and the Diver-Gate(M), the Diver-
Gate(M) is able to download the data from the Diver datalogger and the baro datalogger of the Diver-DXT.
To protect the Diver-Gate(M) against environmental conditions a rubber protection guard is provided. The Diver-
Gate(M) technical specifications can be found in Appendix IV.
