can't use traditional ni-daqmx on LabView 8.2

[ferramis]

Hej,

We have a bunch of quite established VI's using in our laboratory and updated recently our old MACs with Labview 3 or 5 or 6 to new Imacs with  NI-USB 6009 acquisition boards running on Win XP on MAC (the USB cards had problems on MAC Os 10.4). The problem we have is, we want to use the old VI's
on the new iMacs with the new cards. Unfortunately I can't see any traditional
NI-DAQ VI's on the new LabView 8.2, which makes it impossible to use the old
VIs. We will rewrite them within the next month using the tutorial: "transition from traditional ni-daq to ni-daqmx", however for the time being we want to use just the old VI's using traditional Ni-daq (ai read, config, start, ...)
If I open Measurement & Automation I see under Software-Traditional NI-DAQ, that 7.4.2f3 is already installed. Is there
anything else we can do to not have to rewrite all over archives? Thanks in advance.

I think there has never been traditional DAQ for Mac OS X. And it took quite some time to get DAQmx on there. So It would appear that you are out of luck if you do not want to go back to the old machines until the transition has been finished.

On a second read I see that you use WinXP on those Macs. Welllll .... have you made sure that DAQmx works there without glitch? DAQmx for Windows really was developed for Windows on PC sytems and I wouldn't be surprised if there would be just the few small differences between how everybody builds PCs and how Apple believes they have to be done, that could make some of the low level DAQmx device drivers trip over.

Traditional NI-DAQ is available in 8.2, I can see all the VIs just fine. Maybe you just didn't specify it when you installed LabVIEW. I would run the installer again and see if it says it is installed.

Do you see a Traditional DAQ subpalette on the Measurement I/O palette?

Are you using Bootcamp or Parallels?

What kinds of problems did you have with the 6009 under OS X? I have one (which I have not used very much yet) connected to my G5 running under DAQmxbase. I have access to an Intel based Mac where I could try some things.

Maybe I should mention that our iMacs have a Intel Processor and that we were told that LabView on MACs with Intel Processors is an unstable combination. We were even told to install WinXp on the MACs to use Labview in combination with the USB cards. I installed the traditional Ni-daq software again and as before I can see it under Meas.&Automation, but if I go to LabView I don't see any traditional VI, like AI read. Are they maybe hidden somewhere?

[ferramis]

I forgot to mention, we run WinXP via bootcamp

[johnsold]

Can you give specifics about the data acquisition? Sampling rates, number of channels, digital or analog,...

I will try this on my systems to see if I can help.

I have run the attached VI on both a PowerPC Mac (Dual G5) and on an Intel Mac (MacBook) under OS X 10.4.8 with LV 8.20, NI-DAQmx Base 2.1, and a USB-6009. I connected one of the digital output lines to one of the analog inputs. It will run one channel at 48000 samples per second or 4 channels at 10000 samples per second. Some combinations of sample rate and samples to read may cause various overflow errors. At very short delays on the digital loop (milliseconds to wait < 10) OS activity becomes obvious as software timed digital out varies.

I am curious as to what you have tried which did not work.

Hej,

Today I instelled Labview 8.2 also to the MAC OS 10.4 to see if it was rather a problem of 8.0. Strangely the installation was quite fast and now I am performing the mass compiling. If I open a blank VI and search for any Measurement I/O I don't see any VI. I am now totally confused and do not see where the error comes from. On the PC I still saw at at least the new VI's, but not the traditional VI's.

I will follow the hints posted here and than come back with hopefully lesser questions.

You can download the latest version of DAQmx Base (2.1, I think) from NI's web site. It may not be on the LV installation disk.
