Hi all,

I would like to advertise that I got robbed of my bag in the train leading from Bruxelles-Midi to Brussels-Airport.

My OSTC 2N nr 6131 was inside with many other belongings. The bottom line was customized with "Daniel Flipo DAN256603".

If this OSTC shows up on forums or anywhere, be ...

Thanks Lionel for this interesting link. It answers quite well to my questions :)

Hi all,

I notice that different computers give very different values for Nofly when carried by people diving together, so I wonder how the Nofly time is computed.

1) OSTC takes 60% (customisable) of the total desaturation time. OK, could anybody explain to me the rationale beyond this choice?

Hi Tom,

Are you aware of ``Isobaric counter diffusion''? the basic rule is :

Never let the partial pressure of Nitrogen rise (significantly)

When you switch from TX22/36 to EAN26 at 40m, you switch from 42% to 74% N2,
which is an increase of 76% in PPN2!!!

See f.i. the book "Deco for Divers ...

Hi all,

In another thread (OSTC 2N V 2.7 updated with a problem) I suggested a change for the OSTC menus, but I admit I should have opened another thred, that's what I do finally ;)

I find the "CCR Setup" a bit hidden inside the "More" menu.

I would suggest to move the "CCR Setup" menu one level ...

Hi all,

I find the "CCR Setup" a bit hidden inside the "More" menu.

May I suggest to move the "CCR Setup" menu one level up? i.e. swap
"CCR Setup" and "Reset Menu" to have

Menu:
=> Logbook
=> Gas Setup (or OC Setup?)
=> CCR Setup
=> Setup
=> More:
====> Reset Menu
====> Set Time ...

Hi everybody,

CF25 is named "Divisor Decoplan" in Firmware 2.70. I am puzzled about the data I get in the logbook with CF25 set to 6 and sample rate set to 10 (default).

Reading the documenation about Custom Functions, CF25 is described as "Debug" and should be left to the Default Value 0.

As far ...

Hi everybody,

Reading the latest ostc_interface_description.odt (dated 2013/05/26), I have a question about CCR mode: I do not understand how switches to bailout are recorded into the logbook.

For each dive in CCR mode, the 5 possible diluents are recorded in the header (bytes 19-28), it sounds ...

Agreed! this might be achieved by moving the "Reset Menu" into "More", thus one line would be freed in the main ...

I have added a Perl script (ostc_cf.pl) which writes to a text file the list of 'Custom Functions' having been changed (and only these) together with their default and ...

Hi all,

While working on Perl scripts to print my logbook with LaTeX, I stumbled upon strange things in OSTC.DMP files (produced by libdivecomputer). The files were provided by Jan (Solodiver).

The dives were done in CCR mode with firmware 1.95, but dumped after 1.96 was installed.

1) There is an ...

Hello everybody,

I have released a new parser written in Perl to convert OSTC.DMP files produced by libdivecomputer to UDCF format. It should work with both firmwares (1.90) but has only been tested with the old format (1.90).

It is available here . If you do not read French, get file "loogbook ...

@matthias

Matthias, can you confirm that

(OC/CC, GF or not)
values are recorded in the OSTC's internal logs?

In CC mode, are the setpoints changes recorded in the tags?

If the format of OSTC's internal logs is described somewhere, please let me know.

Thanks,

Daniel.

Hi everybody,

Thanks to some of you, I got some logs from JDiveLog with the OSTC Mk2; I'll be able to use my own OSTC only late March ;-(.

Those who are interested can download a beta version of my software to preview dive-logs (extracted with JDiveLog and printed with LaTeX) from here .

I read that some of you are interested in software for logbooks, I don't know if what I am working on can be helpful, so I'll explain what I am doing.

Hi all!

I have just bought an OSTC Mk2 computer and I am currently working on (free) software for Linux to display and print the logs with LaTeX, the same way Andreas Becker did for Suunto Computers (I have a Suunto Vyper and I have been using Andreas' software for years).

If some of you could ...
