Non responding unit

[Francois]

Hello,

My OSTC 2N has been off for several month (new baby boy!).
When trying to switch it on yesterday I had a white flash then black screen. I connected it to my computer to charge the battery. I just had the orange led flashing. When pressing the button: again a white flash then black screen.
This morning after a full night charging the orange led was still flashing. I disconnected it from my computer... and now the screen is black, no orange led anymore even when I plug it again to the computer. The computer doesn't see the unit. The firmware is the one installed when I bought the unit (in May 2011).

I hope you can help! I bought the computer when I couldn't dive because of the birth of my baby, and now that I can go back in the water I cannot switch it on

Thanks,
Francois

Actually the orange led is flashing again when connected to the computer.

Hi,

The LED has some low-level debug functionality, e.g. if the battery has been discharged very deeply.

Is it flashing once/second, twice/second or three times every 10 seconds?

To start, you can also hard-reboot the unit with a magnet near the mid-screw at the back of the unit. USB must be attached in order to reboot it this way. Most likely, the unit will show some debug informations (A few numbers and letters) then, please write this down.

Regards,
Matthias

When I plug it to the computer, it is twice per second.
When I press the right button, the screen has a single white flash, then the orange led is flashing once per second for a minute or two and then back to two flashes per second.

I will try to find a magnet and provide the info displayed.

Thanks,
Francois.

Doesn't look good
I tried with the magnet.

When I put the magnet behind the unit, it is black no flash at all.
As soon as I remove the magnet:
- the screen flashes white once
- 10 rapid orange flashes in a row
- a pause of about 3 seconds - no lights at all
- the screen flashes white once again
- orange flashes, one per second during about 10 seconds
- then back to 2 rapid orange flashes per second

When disconnected from the computer, no led. If I press the right button, a white flash on the screen then nothing more, even if I press the button again.

Apart from the white flashes mentioned above, the screen stays desperately black...

Anything else I can try? Or is the only option to send the unit back to you?

Thanks for your help,
François.

Hello guys,

Any advice?

Regards,
François.

Ok, I had the same behaviour the other day when the update process went wrong.
I just found a magnet (not so easy in an hotel room!) and made this procedure:
* plug the OSTC to the computer
* launch Jdivelog, prepare it to flash the device
* put the magnet under the OSTC and remove it
* flash the firmware
* wait a minute (or two)

It may work with the Bootloader V1 but I haven't tested it.

François, if you still have problems, send me an email (stephane POINT acounis @ free POINT fr).

[heinrichsweikamp]

Hi,

I'd recommend to shorten this by sending it to us (Or your dealer) directly. It could be just a Firmware update issue - but it could also be some kind of hardware defect. In both cases, this should be cleared quickly at our place. We always keep some units for warranty replacements, so no need to wait.

Matthias

Bonjour,


désolé de poster en français mais mon anglais est trop vieux et trop scolaire.
S'il se trouve une bonne ame pour traduire...
Je squatte le post de François car je pense que j'ai le meme probleme.

J'ai acheté aussi un OSTC 2N fin 2011.
Il a 6 plongées actuellement.

Aujourd'hui, j'ai connecté mon OSTC au PC et j'ai ouvert OSTC planner pour changer les valeurs des GF.
Et là, l'OSTC est parti plonger à 93m, d'un seul coup d'un seul
et il y reste (pas moyen de lui indiquer de remonter)

aucune led ne clignote ; juste la led bleue derriere le "e" de Weikamp qui est allumée.

l'OSTC est visible sur mon PC (port com 37) ; par contre, je n'arrive pas à "dialoguer" ni avec OSTC planner ni avec JDIVE LOG.

j'ai bien sur baladé des magnets sur la partie arriere de l'ordi, sans succes.

comment puis je faire ??

merci de votre aide

bonjour Christophe,

je me permets de traduire ton message

Hello,

sorry to write in French but my English is too old and too academic.
If there is a good guy for translating ...
I'm using this post because I think I have the same problem as François.

I also bought a 2N OSTC end of 2011.
It currently has six dives.

Today I connected my OSTC to my PC and I opened OSTC Planner to change the values ??of GF.
And then, OSTC dived to 93m, all of a sudden one
and it remains there (no way to go back)

There are no yellow LED blinking, just the blue one behind the "e" of Weikamp.

OSTC is visible on my PC (com port 37); but I can not "dialogue" with OSTC Planner neither JDIVE LOG.

I have used magnets on the back part of the computer, without success.

how can I do?

thanks for your help"

thx Laurent for translation

With USB power attached? It will only work when USB power is present.

Matthias

[Christophe 38]

yes !

with usb power attached.

I was phoning Laurent during the test and trying many possibilities
OSTC was in port com n°37

bonjour

ça vient de se débloquer :
l'ostc n'etait pas reconnu par OSTC PLANNER

je viens de lancer jdive log et je suis rentré dans "dive computer" et reinitialiser les données de décompression
et l'ecran est revenu normal (avec la led orange qui clignote au rythme d'un coup par seconde environ), la "pile" jaune (et un CNS de 255 lol) et déssat 85h39

par contre OSTC planner m'affiche (toujours) dans la fenetre de droite :
Connection COM37
ECHEC: Downloading OSTC configuration

je peux afficher les menus normaux de l'OSTC

je n'ai plus "qu'" à attendre la déssaturation de l'ordi et voir (je plonge vendredi, samedi et dimanche prochains

merci de votre aide

amicalement

Translate

"hello

the issue is resolved : OSTC was not recognized by OSTC PLANNER

I started jdive log, went to "dive computer" and rebooted the data decompression
the screen came back to normal (with the orange LED that flashes with a shot per second), the "stack" yellow (CNS at 255 lol) and dessat for 85h39

but OSTC planner still displays in the right window :
Connection COM37
ECHEC: Downloading OSTC configuration

I can display the menus in the OSTC

I do have to wait and see for desaturation, I dive Friday, Saturday and Sunday

thank you for your help

friendly"

Sorry for interruption but: Does every OSTC 2N have such an LED? Where is it located and why didn't i read about it in the manual?

[heinrichsweikamp]

Yes, all 2N and Mk.2 have these. They do not show any important informations when in normal use. They're only for debugging and trouble shooting.

regards,
Matthias

[scubatinoo]

Thanks Matthias. Could that LED also be used to show the charging status of the battery during charging? Normally i plug my OSTC on my Computer and unplug it after a while - without knowing if the OSTC is fully charged or not, unless i turn it on...

[swissdiving]

The orange LED blinks on my 2N when charging ever half second or so. When I have Desat I get to blue LED flashing.

[scubatinoo]

@swissdiving: interesting, i've never seen this LED on my OSTC...

[swissdiving]

At the bottom of the 2N screen, in the center between the S and the W

pheeewww, took me quite a few shots with the camera to get light showing on the pic!!!!

[scubatinoo]

Nice shot
Did you have to turn on any special settings for that? My OSTC never showed something like this, not during charging and not during desaturation nor anything...

[swissdiving]

Tinoo,
Nope, never turned on anything...
...all my 2Ns did/do it.

[tiefunten]

Mine also shows this blinking. Scubatinoo, it is not very bright so before writing HWK that it is not working take another close look

[swissdiving]

Or tinoo is color blind or maybe his ostc never gets wet!
@tinoo
Only kidding!!!
