Synchronised DAQ with 2 PCI-cards

Hi folks,
we want to use two (2) synchronised PCI-6071E DAQ cards in one PC. At
the moment we use software triggers. Is it possible two get the
software trigger for device 2 from device 1? Or do we have to use an
external trigger what is not impossible but it needs more work? Do any
DAQ vi exist for two DAQ devices?
Thanks for help, Felix

Software triggering in this case might be possible, but the better solution is to start things with a hardware trigger. Any computer running a commercial OS will have varying amounts of latency that will make reliable software triggering problematic. What's more, the faster the event is that you are trying to capture, the worse the problem gets--and sliding snow is very fast.
I understand that external triggering is more work, but you get much better results. Also the only tricky part will be generating the trigger. The code for a hardware triggered acquisition isn't any more complicated than software triggered code.

Upgraded to USB 2.0 with pci card...works 1 out of 10 times????

Hi,
Anyone having this problem? I installed a pci card with usb 2.0
The high-speed bus is recognized in my "about this mac". However, if I hook up my ipod or any device for that matter, it doesn't recognize it. Do I just need to wait longer? When I first installed the car I did have it connect a few times. But it's very inconsistent. I'm running 10.3.9 and I'm about to upgrade to 10.4. Might this help?
Thanks in advance
Pete

What brand/model card did you install. Not all USB 2.0 PCI cards work in a Mac. Your best bet is any card with a NEC PD720100 or PD720101 chipset (xlr8yourmac results recommend the same). Read this for more feedback: http://www.xlr8yourmac.com/firewire/fwusb_card_deepsleep.html
Stick with the NEC chip, and try NOT to use drivers, OS X doesn't need the drivers.
All of these Cards are NEC chipset based

If you plug your mouse imto the card, does the mouse work?

I have found a person who has a driver software to connect Labview with PCI card. But he says that i need to download a freeware software to configure the PCI card. But you have mentioned that freeware is for GPIB boards. Is it correct ??

I have found a person who has a driver software to connect Labview with a general PCI card. But he says that i need to download a freeware software from NI website to configure the PCI card. But you have mentioned that freeware is for GPIB boards. Is it correct ?? Is there any other way out ??

I would ask the person who told you about the freeware software to help you find exactly where it is. I am not aware of any freeware software for configuring motion PCI cards but maybe the person you know might be able to help you locate it.

Problems with PCI card on my Mac G5

I have been having random system wide freezeups on my G5 2.7 purchased as a refurb from Apple store.com back in late March. Other crazy symptoms are Logic Pro freezing, ie - application freezes, and various funky glitches while recording and then stopping playback. I have had the computer put through a battery of diagnostics at my local Apple store and all components, RAM (4.5GB), 3 hard drives (the Mac HD, the audio hard drive mounted internally and a Lacie firewire 800 drive for the Ivory samples), the computer itself, optical drive - all come up perfectly sound.
Using my Apple Care technicians instructed me to elliminate one by one my peripherals which include the Mackie Control Universal, Motu Micro Express Midi Interface, Ivory Grand Piano Software, my Korg Triton, and in the beginning my Echo Mia PCI card. Oh yeh and Logic Pro 7.2 was removed to see if that was the problem.
The only thing that caused the problems to stop was the removal of the Echo Mia card. Also tried changing it to a different slot to no avail. So the Echo tech support was contacted and even though they refused to believe that their card was the problem they took it back. So since the Mac 1/8 inch inputs and outputs are anything but professional filled with groundloops, beeping and hums I did a forum search on many differnet forums to find a card that would fit my needs inexpensively until I finally get the Apogee Ensemble that I'm waiting for. The same name came up for bringing audio into a Mac via the PCIX slot for a small sum of money - ESI Juli@. Many people said this was a quality unit with a good track record for being used on a G5. I have the most updated drivers from the ESI company. Darned if I'm not discovering the same freezeups and glitches with this card.
I have come to understand that these cards should work in my computer, hassle free. I have a G5 2.7 with supposedly 3 PCIX slots. What am I doing wrong here? Are there voltage issues here?

Turned out to be a corruption in some Logic preferences. I believe this was because of a bad chip of RAM I had. It took weeks to figure out why I was having glitches and system wide freezeups. One day the Apple Hardware tests came up perfect and then another day the "quick test" showed a RAM error.
I had to delete a file called "logic" and a loose file named "apple.logic.plist" (something like that). As a result of that I lost my templates and settings. Then I had to reset the startup assistant in Logic. I think a handy shortcut, although I am a newbie to Logic, is to formulate a song (file) and name it "Marks template number one", then save it as a template but don't erase the file. Then if you lose your templates like I did, because of the corrupted preferences, the song file still is in your hard drive and you'll just have to save it as the template again.

845PE Max-L problem with pci cards

Got a weird issue with the 845PE Max-L and was wondering if anyone else has come across this. I work in the RMA dept of a nationwide computer wholesaler and recently we've come across atleast 4 of these boards with the same problem. under windows xp it will not detect any pci cards. tried various sticks of ram, video cards, network cards, modems, usb cards, hard drives, pretty much anything we can think of to check for incompatiblities. did the latest bios flash, installed the newest updates in windows xp, but still cant get these boards to detect any pci cards whatsoever. yes we tried different power supplies and yes we tested the pci cards in other systems to make sure none of it was defective, all passed with flying colors. now here's the kicker, under windows 2000 it DID detect the pci cards, however i was unable to successfully load any drivers to any of the devices. We've made a call to our MSI rep to find out if anyone else has run into this or are we just dealing with a bad batch. unfortunatly noone from MSI has contacted us back yet so i decided to try and post here to see if anyone else has come across this odd situation. Any feedback would be much appreciated.

Weaksauce;
Two replies two separate motherboards. In reference to the 865 / 875 motherboards not recognizing PCI cards I think your link has something to offer. :biggthumbsup:I'm not going to go back and test it but the reason the PCI cards were not recognized may very well be that the old bios did not properly inspire the intel inf utility to install the correct drivers. The force method you suggest may well overcome that particular problem. I would still suggest that merely doing the BIOS upgrade first is the more elegant approach.
Regarding the usb problem with MS update, the inf chipset article would appear to have little to offer. The 845 MB uses the Intel 845 chipset which is ICH4 by the way. The updated inf utility was installed in as early in the process as possible.

Problem with PCI Card Slot

Is there a way to try to test this thing's PCI Slot?
I have a Dazzle SmartMedia Card Adapter and it has stopped working. Nothing happens when inserted. I bought a 2nd card and trying to install it, the same thing. Nothing. So now, I'm trying to decide if its the card slot, the upgrade to 10.4.10 or Sophos Anti-Virus software.

Hi, Marty. Your card slot's connection to the logic board may have loosened; that happens sometimes with Titanium Powerbooks, especially those that are handled and transported often. Flexing of the PB's case and frame is the cause. If that's your problem, it's very easy to remedy.
Release your keyboard catches and gently tip the keyboard back over onto the wrist rests and trackpad, being careful not to jerk its ribbon cable. You needn't disconnect the cable. Beneath the normal positions of the X and D keys is a translucent plastic rectangular tab about 1" x 3/8". That tab is the card slot's connector to the logic board. Press down very firmly on it with two
fingertips. If you feel or hear it shift even the smallest amount, it was probably a little loose, and is now properly seated again. Put the keyboard back in position and test the card slot. Let us know how you fare.

Will DAQ with PCI-4474 and a Kinemetrics Episensor ES-U sensor work?

We are planning to setup a DAQ system measuring some low level vibration. The system considered will be a PC based card, PCI-4474 and a Kinematrics Episensor ES-U accelerometer. Before purchase,we would like to find out is there any compatibility issue between these two devices or any complicacy in setting them up. Suggestions are welcomed. Thanks.

Hi Zenz,
I just want to ask how is your project going regarding the PCI-4474 and a Kinematrics Episensor ES-U accelerometer. I am using the same model of accelerometer from Kinemetrics but now it's power by an old ADC from Kinemetrics also. Now were planning to shift to NI DAQ including the power supplies. Were more on vibration testing.
Thanks

Will it work with PCIe cards for PCs?

Now that the need to support OpenFirmware is gone, would I be able to retire my gaming PC by pulling its 7800GTX and putting it into a Mac Pro?

Now that the need to support OpenFirmware is gone
OpenFirmware may be gone. But EFI is the firmware used on Mac Pro's.
Both OpenFirmware and EFI need a compatible firmware on the video card held in the unit's own EEPROM.
In the PC World, it's usually referred to as a VGA BIOS. Although, it also controls some of the workings of the card and it's identification to the computer (usually).
The big thing is that the card's own firmware allows EFI/OpenFirmware to use the card to boot up. Without it, the card can't be used during boot, and probably not even after the drivers have initialized (if they even recognize the card).
Anyone trying the PC Cards should probably know this.
Unless it has a EFI compatible firmware code on the card, it simply won't work.
The only way it would is if Apple had an identical version of the PC Card, and it was possible (??!) to pull the firmware off the Apple card and flash it into the PC card.

How to simutaneously use 2 PCI cards, one with traditional DAQ, the other with DAQmx?

Hi,
I am currently trying to debug a system that used to work.. but sadly isnt anymore
A single computer contains 2 PCI cards (6110 & 6036E). The 6110 card is controlled by a fairly old software, programmed in labview, and hence, using Traditional NI-DAQ. The 6036e card is controlled by a more recent soft, programmed in LV as well but using DAQmx.
the AI/AO of the 6110 card is only momentarily used (20 sec consecutively, every minute) while the 6036E card is continuously receiving and sending data on its AI/AO.
Now the problem: the program that control the 6036E card freezes every time that the old prog access the 6110 card.. and then it works again perfectly until the next time that the 6110 card is used.
So my question: how can I make those 2 cards work simultaneously?
I dont think that it is because of the software nor because of the computer lack of memory/CPU if it used to work in the past. It might be about a wrong configuration of cards in the MAX but I couldnt find anything wrong there (no problem when accessing AI/AO of both cards through "test panel")
Thank you very much for you help.

That's what bugs me. The only thing that those 2 cards share is an AO of the 6110 connected to an AI of the 6036.
For the rest, nothing is common. The 1st program only deal with device1, while the 2nd prog only access dev2. There shouldnt be any problem and everything is working fine separately. Hence, why I was wondering if the traditional daq and daqmx might conflict on a same computer.
I just cant find out why the 2nd program controling the daqmx card just freeze everytime the 1st program access the traditional card. It actually doesnt freeze completly but becomes soooo slow, with about only 2 iterations of the main while loop during those 15-20 sec (instead of the normal 3-4000 iterations during such a period).
The computer specs are a 2.2ghz proc for 1G of ram and running XP, so it should be ok.. even though the computer does slow a bit down when the 1st prog access the traditional card.

RTSI cable configuration with PCIe 1433 card

Hi All:
I tried to trigger my line camera with RTSI signal.
The layout is: trigerr signal is generated from one PCI card 6259 (Dev2/ctr0). The line camera is connected with one PCIe 1433 card, and the two cards were connected with RTSI cable.
The problem is that how to register or configure PCIe 1433 with RTSI cable in MAX, it seems I can only configure PCI card within RTSI cable ......
If it is true, how should I do to rout the trigger signal to the camera, such as "route Dev2/ctr0 to Trigger line 0"?
Below is printscreen of MAX Configuration. Attached is my VI.
thanks a lot.

Thanks a lot, the post helped.
But I am still confused with the details:
To camera and PCIe 1433 configruaration, as the attached pictures shows: RTSI is configurerd as Camera Control Line as number "2"; the exposure control of camera is defined as "triggered".
In previous attached VI, you may find that the IMAQ configurer trigger is applied to define trigger type as "RTSI", trigger number as "2".
About ttrigger signal from PCI 6259 (Dev2), digital pulse is generated and output terminal is defined as ctr0 ( seems only ctr0 or ctr1 is option).
So I still do not know how to route signal from "Dev2/ctr0" to "Imag0 CCL 2" in labview.
By the way, I read the online example "LL Triggered Ring using DAQmx Pulse Train", http://www.ni.com/example/29476/en/. Within this VI, the DAQmx Connect Terminals VI is applied to route the counter's output to a RTSI pin so the signal can be used by the IMAQ device. However Dev2/ctro is not recognized as scour terminal, only other items such as PFI, APFI or RTSI are avaible, and output signal source is also limited with similar things, sounds like just internal connectrion with Dev2.
thanks a lot.

IPod touch will not work with USB 2.0 PCI Card?

I have a dual processor PowerMac G4 that has USB 2.0 via a PCI card. When I plug in the iPod nothing at all happens. I haven't read anything about PCI cards not being compatible with the touch. Is anyone else having this problem?

Just thought I'd add my 2 cents...I've got the same problem...I've had a Keyspan USB 2.0 5 port card in my Dual MDD G4 for years and it's worked fine. Well, until a few days ago when I tried updating some stuff on our iPods. It would initially start working then lose connection. Now nothing at all with 5 iPods. It won't even show up on the desktop under Disk Mode. I did the same and it works fine under the old stock USB 1.0 but slooooooowwww. Is this yet another problem with Leopard? I've searched the Keyspan site and they don't have any updated drivers. Guess I'll look for a Belkin as well...ugh!!! Leopard is horrible! First no printer drivers, then no iSub support, now this!

IPod 30GB will not work with 3rd party USB 2.0 PCI card

I've had an IOGear PCI USB 2.0 card (GIC220U-BIO) in my Sawtooth for some time now, and have been using it flawlessly with my Canon i860 printer, and Canon LiDE 30 Scanner.
Just recently I received a Video iPod (30GB) and wanted to take advantage the high speed USB bus offered on that card to sync my iPod. The problem is, when I plug in the iPod to the USB port on that card, I get the transparent gray box telling me that I need to restart my mac by pushing the reset switch, or holding the power button for several seconds (in other words, freezes).
The iPod works fine with the built-in USB ports (albeit slow), as well as the high speed port on my iBook G4. Why am I getting this error? There are no drivers or firmware updates for this PCI card available.
Is there a solution?

Yes, use a different USB 2.0 PCI card, like from Sonnet. I use a Sonnet in a G5 and it works great. There are (at least) 2 USB chipsets and I find the TI ones are great and the other not so great.
The fact it works on 1.1 and the 2.0 on the G4 at least tells you it is not the iPod and a USB 2 card is $20 or $30 at the most.

Error Code 10 with GPIB PCI Card

PC used: Dell optiplex GX110, lastest Bios release, Windows 2000 SP4, GPIB Drivers version 2.2, Local Admin session.
After having install the driver (without the GPIB)and plug the card, this one is automaticaly recognised by the Os.
But, after the reboot (asked by the OS to validate the installation), the GPIB card appears, in the device manager, with an error code 10 (not started)....
I tried with two (new) differents GPIB PCI Card, two OS (First time with NT4.0 SP6 Drivers 1.7 and now, Win2000 SP4 Drivers 2.2) and with two PCs Dell Optiplex GX110 !
I even tried with a "Ghost" from an other PC (also an Optiplex GX110, with the same model of GPIB Card)
-> I obtain the same error each time !
Help me please..........

Hello,
Could you give me the exact reference of the board (PCI-GPIB, PCI-GPIB+, AT-GPIB, AT/GPIB-TNT...)?
Is the error code displayed on the Windows device manager (in the properties dialog box of the device)?
What is the exact description of the error code?
A PCI-GPIB installation do not need to reboot the OS if the NI-488.2 driver is correctly installed. The board should be recognized in MAX and you must be able to scan for instruments and start I/O communication with the device from test panels in MAX.
Update me as soon as you receive another feedback.
Regards.

Wmp 11 pci card work with WPA encription?

I just purchased a new 54G wireless access point since my new laptop (with Vista) doesn't seem to want to give "full connectivity" when using WEP security activated.
I now use WPA and the laptop hooks up fine to the new access point. My problem now, is all my other wireless computers have the older wmp 11 pci cards, and I don't see anywhere in the setup where I can select "WPA" security so they can see the new access point.
Is there a way that they can work with this new access point with WPA?

I have a WMP 11 2.7 - I know for a fact it supports WPA2 because I am connected to the net using it and WPA2 right now.
I knew it had to work cos I got it working under Ubuntu linux using this
http://ubuntuforums.org/showthread.php?p=1071920&mode=linear
very helpful guide.
Could not however get the damned thing to work on windows using any of the drivers from this site. So I went back and had a look at the linux guide and found a simple solution. Download this driver
http://sidulus.textdrive.com/bcmwl5sys.zip
Go to C:\windows\system32\drivers\bcmwl5.sys rename the driver there to bcmwl5.old.sys and unzip the new driver to that location. Restart. Hey-presto you should now be able to connect to WPA and WPA2 networks.
I think this will probably only work for the 2.7 version as that is a Broadcom chipset.
You know what really bugs me tho? I shouldn't have to be telling you to do all this, I shouldn't have to do it myself either. Why the hell does this card not connect to WPA with the drivers supplied on this site?!?!?

External Drives Won't Mount with SIIG Fire WIre 800 PCI Card

I can't get any drive to mount using this card. It's the SIIG FW 800 3 port PCI card. I've also got the SIIG FW 400 and I think a Belkin 5 port usb PCI card. I've removed the other cards leaving just the 800. I've moved them all around into different slots. Nothing Changed. I've reset the PRAM and the NVRAM. I've Unplugged system and let it sit for a while. I've had only one drive connected to the 800 card and no other 400, 800 or usb peripherals connected. That didn't help either. Again, this is the second card, so I have to assume that the odds of getting to bad cards in a row is a long shot... right? I have to assume that it's the G5 but the other cards work when put into any of the PCI slots. I know all the drives work. I'm just kind of baffled here. Oh, and in the system profiler the drive shows up as "Unknown Device" but it never mounts on the desktop. Also drives connected to the 800 PCI card don't show up in programs like Diskwarrior or Drive Genius. Starting the drive while Disk Utility is open also does nothing. So, I'm at a loss. I spoke with SIIG tech support and they said they had no idea but they could test the card if I send it to the. That would at least confirm or deny if the card is faulty. I think the card is ok and the mac is just messing with it somehow? Any Ideas? Could resetting the PMU help? I've also cleared my cache and defragged and rebuilt the data directory and all the usual utility stuff. So the system is peppier but still no drives mounting on the 800 pci card? Please shout out if you have an idea... Thanks..

I eventually gave up. I will probably get another card at some point but it probably won't be a SIIG card. Even though they are recommended by digidesign I just doesn't seem to want to work with my G5. Maybe it's some kind of weird software conflict blocking the functionality of the card? Don't know. Two cards in a row were non functional. Something is gummin up the works and the PCI slots work with the other cards I have. The only thing I did not try is plugging in the optional power connection to the FW800 card, which is supposed to be optional. I called SIIG and they had no idea what the problem was and they also said that the power plug would not make a difference for the problem I was having. Anyway, I'm gonna keep monitoring posts to this cause I'd love to hear the answer.. but I'm throwing in the towel. Good luck to the rest of you still trying to solve the riddle.
