INTERFACING TO A PC
Using a special interface unit and a dedicated
Windows software application, it is possible to
transfer data from the LogBook of an DARWIN to a
personal computer, and to configure the various
SET parameters from a personal computer.
The communication between the DARWIN and the
PC is optical, and takes place via an RS232 serial
port of the PC and the special interface unit which
converts the optical signals into electrical signals
and vice versa.
The data transfer procedure is as follows:
The user selects PC mode (fig. 44). In this condition,
the transmission will be managed by the interface
program running on the personal computer.
Fig. A shows the different ways for accessing PC
mode:
By pressing the <Mode> button from LOGBOOK
mode.
By pressing the <-> button from OFF mode.
By pressing the <-> button from DIVE mode.

FAQ
Q:
If the level 1 low-battery indication appears
(i.e. the battery icon illuminates) when the
computer is in use, for example during a dive:
how many dives can I still do before replacing
the batteries?
A:
Approximately 5 dives. However it is good
practice to replace the batteries as soon as
possible.
Q:
If the level 1 low-battery indication appears
(i.e. low battery icon and audible alarm) when
the computer is switched on after it has not
been used for some time, how many dives can
I still do before replacing the batteries?
A:
Because the computer has not been used for
some time, it is impossible to know when the
battery charge first dropped below level.
Replace the batteries before your next dive.
Q:
When I replace the batteries, will my LogBook
dive data be lost?
A:
No.
Q:
When I replace the batteries, will I lose the
data of my last dive?
