Some Graphs Greyed Out
Some Graphs Greyed Out
I am syncing my Oceanic Atom 3.1 with Dive Log DT and I noticed that some of the profile graphs are greyed out; No Decompression Limit and Remaining Bottom Time. If I recall correctly from the manufactures software it did graph those two things so the data should be there. Is there a reason it is not showing up in here?
Re: Some Graphs Greyed Out
If the graph is greyed out, then it means that that information is not available for that dive. The only manufacturer that gives "remaining bottom time" are the UWatec ones. The majority of manufacturers give "no decompression limit", including Oceanic. (It's usually an "either or" situation).
I just took a look, and we don't know how to decode the NDL information for the Atom 3.1. There is an open source library that has the information on how to decode the memory from various manufacturers dive computers and their various models, and this library doesn't support NDL for the Atom 3.1. A lot of manufacturers don't share the details of their dive computers with 3rd party logbook developers such as ourselves, so we rely on people "reverse engineering" the information. If you are willing to take the time and send me a Pelagic DiverLog (Lite) file of your dives, and a "memory dump" of your Atom 3.1, I can take a look and see if we can figure out how to decode the NDL information for the Atom 3.1. It may not happen "right away", but we would need this information to even get started.
If you do want to go ahead, it's probably best to email our support address. I can send more detailed instructions on how to find the Pelagic file and also how to create a memory dump.
Thanks,
Janice

Re: Some Graphs Greyed Out
I'm very new to the DiveLogDT software. I have loaded an existing log book that was converted from SmartTrak and downloaded some new dives directly from my dive computer. I just discovered that the dive profiles in DiveLogDT display only the remaining bottom time parameter for my dives. At least some Uwatec computers record both no decompression time (NDT) and remaining bottom time (RBT). Of course the NDT is based on nitrogen absorption. RBT is based on tank pressure and interpreted breathing rate. I have used both a SmartCom and a G2. Both computers display both NDT and RBT during a dive. I previously used the SmartTrak software when I had the SmartCom computer, and both the NDT and RBT data was displayed in that software. The data must have existed in the SmartTrak file that was converted. I have to believe that the G2 computer is capturing both parameters. Is there anything that can be done to recover the NDT data from from the SmartTrak file that was converted? Is there anything that can be done to enable both the NDT and RBT data to be captured for new dives downloaded from the G2?
Thanks,
Mike

Hello Mike,
You are unfortunately running into one of the limitations of using non-"dive computer manufacturers" logbook software.
In the case of ScubaPro dive computers, it's true that all of the decoding of the information has been reverse engineered by various people, without input from UWatec / ScubaPro. But I'm 99% sure that the NDL value for these dive computers is *not* actually stored in the dive computer profile itself. I (and others) have spent many hours looking for it, and it's just not there for us to be able to download.
When you use the SmartTrak or ScubaPro supplied software, they are able to duplicate their own NDL calculations on the Desktop and show you what NDL number "would have" been shown on your dive computer during the dive. Their own NDL calculations are of course proprietary and so we can not, and do not even try to to reproduce them.
So in fact no, your G2 is not capturing the NDL value and storing it. It it just being recalculated by the ScubaPro Desktop and Mobile software.
This is also why we are not able to "get" the NDL number from an existing ".slg" file as well, as it's also not stored in it as far as I know, but this is a PC/Windows only format. I know for Importing from a JTrak or LogTRAK file on the Mac, it is also *not* available in the file to be able to import so the assumption is that it's not stored in the PC file either.
