Can't I Use A Pci Soundcard ???

I have already pasted this message before but I did not got a final answer, so I will try again:
Apache ASC-200 soundcard + NEO2-865LS motherboard
I had the Apached soundcard acs-200 before the I had the MSI 865NEO2LS and there where no problems (I had another MSI mothoerboard then for pentium 3). Then I bought the MSI 865NEO2LS and pentium 4 and put in the Apache soundcard (after disable the audio of MSI in the BIOS) and I had blue-screen errors (once a day during playing audio files, not all the time). Then I took off the Apached soundcard and enable the audio of MSI in the BIOS and it works OK now. The problem is that I want to use the MIDI port of the Apache soundcard, and now I can not do it. CAN ANYONE TELL ME WHAT CAN I DO ABOUT IT????

First of all - have you disabled all the options for your Audio card in the BIOS (I think that the options are 2 but I'm not sure)? Second - have you updated your MB BIOS version (Try using MSI Live Update) and Third - check for new drivers for your sound card. Remove all the drivers for your Sound Card which comes with your MB, shut down and then put your other Sound Card and Install. Let's hope that this will work -

The second frame lost in CAN communication when use NI PCI-CAN/XS2 card

I got a trouble on CAN communication recently.
I need to commmunicate a Cluster with CAN BUS,the baud rate is 500kBPS,the CAN card is NI PCI-CAN/XS2. The operating system is Windows XP.
normally,the PC send a command to Cluster,then read back a frame of data from the Cluster,but for some commands,the Cluster will return two frames of data,and the programe on PC cannot receive the Seconds frame,it lost.
I searched the forum,most of the reslut is the error about CAN BUS overflow,which make the CAN frame lost,but there is not any error report on my programe,and the baud rate is no that fast,I also use another port of NI PCI- CAN/XS2 to monitor the CAN bus,the second data frame never appear,when I replace NI CAN card with Vector CanCaseXL(CAN card) ,and call CanCaseXL's DLL in labVIEW,it can get the second CAN frame,the monitor of Vector CanCaseXL can get the second data frame too.
so,is there some software/hardware configuration need to be done to get the second data frame?
the attached pictures are NI-CAN/Vector CAN monitor and CAN init/write&read in my programe.
Any reply is appreciate!!! thanks

Thanks your code.
I try the code you posted, It still no work, I found you has improved the "Get data.vi",It works better,but the second frame still no shown.
I used the NI CAN monitor in MAX to monitor the CAN bus,there is no second frame shown in the monitor,See attach pictures.but It shown in the Vector CAN monitor and the code call the Vector DLL.
Have a great day.

Pci soundcard for mac g3

Hi,
I have a blue and white Mac G3, my onboard sound in jack has broken and i can no longer record into my mac, i have heard that its possible to use a pci soundcard but i dont know which one as i have searched google but cant find what i need, i dont want an expensive soundcard just a basic good quality soundcard, i am running OS 9.2.
Many thanks, Andy.

I currently use an M-Audio Audiophile 2492 PCI sound card in my Power Mac G4/400 AGP "Sawtooth." It works well and drivers are still available for this card from the M-Audio website.
I haven't checked eBay lately for a used one, but as another post alluded, a decent Audiophile 2492 might set you back around $50US or so. You do need to make sure that the card is designed to work in the old PCI slots -- some of the older cards were factory modified to work in the PCI-X (or whatever it is called) of the new form-factor Power Mac G5s. Almost all Audiophile cards since the G5 model came out have been made to support that slot architecture. I don't know if the PCI-X is backward compatible with the old PCI standard of the older G3 and G4 Power Mac towers.
If you do find a decent used Audiophile card, pay special attention to the RCA style jacks on it. The grounding sleeve of the jack was held in place within its plastic casing merely by the friction of the metal against the plastic. On my card, the grounding sleeve of one of the jacks consistently comes out of the card when I remove the cable, which can be quite an annoyance. The fix is to simply push the sleeve back into the plastic holder.
Otherwise, it's a great sounding card; much better than anything that Creative Labs every put out for the Macintosh. As long as you have fast enough hard drives (7200 RPM or better), your G3 should have no problem using the full 24-bit 96,000 kHz sampling rate of this card.

How can I optimally stream data to disk at 5 MS/s on 4 channels using a PCI-6110?

I am using a PCI-6110 to acquire data streaming from a camera. Data arrives on all four analog input channels at 5 MHz. An A2D clock is attached to PFI8, also originating from the camera and operating at 5 MHz. Finally, there is a Valid-data signal from the camera that signals when the data stream coming in on the four analog channels is actual data (each Validate pulse is about 132 samples wide). This is attached to PFI0. Ideally, I would like to have a program that captures data at the full rate and is correctly synchronized with the Valid-data line. It should also be able to stream to disk for several seconds at least before pausing for the buffer.
Though I'm something of an inexper
ienced programmer, I have attempted programs both in LabView and C (using DAQmx) to resolve this, but I have experienced much slower behavior than I'd like. In LabView, this seems to be the result of slow streaming to disk, such that I have to pause and reset the task every frame (132x512 samples per channel). Using DAQmx in C, I have found it necessary to restart the task after every line (132 samples per channel) in order to correctly trigger from the Validata pulse. Both are far from optimal. I would appreciate any advice that those of you with more experience reading at very high rates from this card may have to offer.
Thanks,

I'm not sure if I fully understand your application, but maybe some of these hints will help.
First your streaming to disk rate is going to vary widely depending on your system. Sometimes using a faster processor helps, but most of the time using a faster hard drive will give you the best performance increase.
Second, writing less data will often have a dramatic impact in streaming to disk applications. If you're reading back scaled data, I would strongly recommend switching to unscaled or raw reads and storing off the scaling constants so you can scale the data off line. This could reduce the required streaming to disk bandwidth by a factor of 4 alone.
Third, since the 6110 is a 12 bit device, you can try compressing two 12 bit samples into one 24 b
it piece of data. This will allow you to store in three bytes what used to take four.
Last, you might consider using your signal on PFI0 as a pause trigger. Depending on the frequency of the pulses on your Valid-data signal, this could significantly reduce the required bandwidth of both the PCI bus and your hard drive. However, since the 6110 uses pipelined ADCs, you need to be careful if the time between valid data pulses is greater than one millisecond. This would violate the minimum sampling frequency of the board and the points in the pipeline that are returned after unpausing (3 in this case) might not be digitized at the full accuracy specification for the device. Because of the pipelining, you also need to be careful how you correlate the data. The first time you unpause for the Valid-data pulse, the first three points will be garbage points. The second and subsequent times you unpause, the first three points are really the last three points from the previous Valid-dat
a pulse. See the Device Considerations->Timing chapter in the NI-DAQmx Help file for more information on timing considerations with pipelined ADCs.
I hope this information helps. Good luck!

Can I use a PCI-DIO-96 with HP Vee 5.0

I'm trying to move an HP Vee 5.0 automated test program to a newer-faster-better computer and in to LabVIEW. But for a short time I need to be able to run both programs, to keep up with production during development and to prove the LabVIEW work the same or better. Can I communicate with the PCI-DOI-96 card from HP Vee? If so how?
I have no manuals for the Vee 5.0 and was unsuccessful in searching both websites.

If VEE has the ability to call a dll, then you should be able to use either traditional DAQ or DAQmx and communicate to the card. You might want to try the VEE Users Group as I doubt if you'll find many VEE programmers here in the LabVIEW forum.

Can I use NI pcie-1430 in linux ?

I want to use NI pcie-1430 in linux environment or a embed linux,. But I don't know if i can get a linux driver and how can i get.
Thanks!.

Has this changed since the orignal post? it's been 5 years, so I would hope NI would branch out a little and support linux for high speed image acqusition, MATLAB does.

Hi Paola,
if you own IMAQ Vision you can just have a look at the examples that comes with your board or you can look at: http://zone.ni.com/devzone/explprog.nsf/6c163603265406328625682a006ed37d/2abaefe05789961686256866007c0d22?OpenDocument.
Without IMAQ Vision look at:

Can you perform simultaneous timed digital input and output using a PCI-6120?

Is it possible to do simultaneous timed digital input and output using a PCI-6120? It seems that timed digital operations require using the group read/write commands, which utilize an entire port. Since the PCI-6120 has only 1 digital I/O port, I would like to be able to use 2 lines as outputs and 1 line as input, and do both in a deterministic fashion. i.e. create a digital signal with known pulse widths and read an input line at a known time after the outputs were set. Is this possible to do with only one digital I/O port?

Hello,
This can be done in LabVIEW. There is actually an example that installs with NI-DAQ.
Below is a link to a Knowledge Base that explains how to find the correlated digital I/O examples.
http://digital.ni.com/public.nsf/websearch/B849664604EB34B886256D12005B5520?OpenDocument
Just take a look at the example titled �Continuous CDIO with external clock (E).vi�

How can I verify that the PCI-6534 is using all of its onboard memory?

When using a PCI-6534 under Windows 98 with NI-DAQ 6.9, I need to transfer a small buffer (8126464 bytes) to the adapter, and get it into the onboard memory. The board is configured for 32 bits output, and I'm using handshake mode. DAQ_GET_DEVICE_INFO tells me that there is 33554432 bytes for each Group. DIG_Block_Check shows that 2031587 words (8126348 bytes) are remaining to transfer. Is that in the PC system memory or the PCI-6534 on board memory? How can I tell if it is safe to reuse the (PC side) buffer? Also, How big is the FIFO on the PCI-6534?

When you call DIG_Block_Out, NI-DAQ first downloads your data into the 6534 memory. Only after the download is done (which should happen at about 80 MB/s) it starts outputting data and DIG_Block_Out returns. So it is safe for you to reuse your PC memory buffer as soon as DIG_Block_Out returns.
This is assuming your entire buffer fits in memory. If it doesn't, NI-DAQ will download all the data that fits and start the transfer, and as more 6534 memory becomes available the DMA channel will fill it up.
The 6534 has a 16 sample FIFO and an additional 32 MB of memory for each handshaking group. So for 32-bit transfers you can fit 8 MSamples, for 16-bit transfers you can fit 16 MSamples (per group), and for 8-bit transfers you can fit 32 MSamples (per group) in the 6534
memory.

Alsa sound and xine engine suddenly stopped using the right soundcard

I have a relativly fresh arch install and was astonished how easy the installation of alsa was. I just installed the alsa-lib package and it automatically detected my PCI soundcard instead of using my onboard chip.
But suddenly (about some hours ago) Amarok refuses to playback on the right soundcard. Instead i get output on my onboard card. I'm using gnome and if i check the Audio settings everything is on "Alsa" and if i click on the "Test" button i get that annoying sine-sound - on the right soundcard. If i try to manually change the sound output in Amarok from "Autodetect" to "Alsa" i get a xine error and Amarok crashes.
Then i tried to define my default soundcard in my .asoundrc:
pcm.!default {
type hw
card 2
ctl.!default {
type hw
card 2
No luck. What's happening here?

I am trying to generate a 50kHz sine wave for ten cycles, then aquire this waveform and store it in a file, I am using a PCI-Mio 16E-4 board, has anyone done anything like this?

I am trying to generate a 50kHz sine wave output on the DAQ card and then simultaneously recieve. I am using a PCI-Mio 16E-4 series board to do this. Has anyone done anything similar. I can generate a 50k wave no problem, and recieve one, but I can not get these vis to run together? Any suggestiosn

Jrod, yes you should be able to do this, actually there are quite a few example programs come with LabVIEW that handles simultaneous analog input and output, I check the specs of the board you use, the board should be able to handle the sampling/generation rate, but make sure for 50KHz sine wave, you would sample at least twice as fast, preferably ten times the generation rate, then this puts the sampling of the board to thew limit.
The program you can try is attached here, good luck with the application,

I want to perform bidirectional i/o using a pci-6534.The problem is that i need to use the same lines for i/p and o/p. is that possible?

I want to perform bidirectional i/o using a pci-6534.The problem is that i need to use the same lines for i/p and o/p. is that possible? And if it is how an i doing this?

Hi I Pant,
The idea that crossed my mind was to tie each of the lines coming from/going to "your device" to two of the DIO lines. Configure one these two ports as input, the other as output.
When you want to read the state of the line, read from the line configured as input. Similarly, use the other port when it is time to write.
Provided "your device" uses tri-state drivers/receivers, or can be used in a "wired-OR" configuration, this may work.
What is "your device"?

HT204384 What are GT/s?- "Computers that use the PCIe bus express their speed as GT/s"? and what else is the card slot used for?

If I understand correctly the card slot on the Macbook Pro is for flash memory? Can it be used for anything else?

Read http://support.apple.com/kb/HT3553?viewlocale=en_US&locale=en_US
for information on the card slot.
GT/s is gigatransfer per second. It takes into account the overhead of the PCIe bus.
