32bit / 64bit PCI slots

[Mark_Eidem]

Hello,

A general question that has come to my attention concerning NIDAQ cards.

We use the E-series MIO-16E-1 and DIO96 cards, historically in ISA/AT bus but of the last few years in PCI bus versions.

We have recently ordered a number of high end rack PCs which have a combination of 32bit PCI and 64bit PCI slots.

What I have found is that it is not possible to mount a 32bit card in a 64bit slot, despite being advised that you can do.... (not by NI I wish to add).

The reason is to do with keyways and voltages.....

In a regular 32bit / 5V PCI slot, there is a key at position 50/51 in the connector. The PCI cards have a small cut out in the corresponding position.

The PCI spec (at least rev 2.1) also provides for a keyway at po
sition 12/13 for 3.3V 32bit cards, however these are not in widespread use.

In the case of a 5V / 32bit PCI card, position 12/13 is normal ground. Visa versa in the case of a 3.3V card at posn 50/51.


For 64bit PCI slots the situation is more complex. In addition to having extra contacts above position 62, they contain both the 3.3V and 5V keyways at positions 12/13 and 50/51.

It is the keyway at posn 12/13 in the 64bit slot that will prevent a 5V / 32bit card from being inserted, and this is our problem today.

What we would ideally like is NIDAQ cards to progressively support insertion into either 3.3V or 5V slots, of either 32bit or 64bit as the PC industry
is moving in this direction and rather too fast for our liking !

Can you please advise me if and when you will support this idea, sooner rather for, the MIO-16E-1 and DIO96 cards.....

Many thanks, Mark Eidem

Hi,
You might want to take a look at the following knowledgebases :

Link1

It is really difficult to say when it will be supported.

Hello Sastry,

I have tried to view the link, but I can not access the page. Is the server available or link valid ?!?

Please advise and thanks for your initial quick reply to my question.

Thanks, Mark Eidem

Hi Mark,
Are you referring to "Link1" ?

Hmm, can you please try it again?? Because that is an external link to the best of my knowledge and it should be accessible.

Please let me know if it again fails.

Sincerely,
Sastry

Hi Mark,

The best way to get to the document referred by Sastry is to search for KnowledgeBase ID 2KA6M0YJ. You can search for it by using the KnowledgeBase link in Option 3 at http://www.ni.com/support.

If it doesn't work for you, you can try this direct link:

Hello Wilbur,

Is was able to find the page with the info you provided, many thanks.

The good news is that at least the newer IMAQ borads are keyed for 3.3V and 5V operation.

The real question is when will we see this on the E-series DAQ boards ?

Many thanks, Mark

Hello Sastry,

The link is down... I have tried a few times now.

The link is below

But the page is unavailable. Is it a public page ?

Appreciate any help, especially if you can access the site

Thanks, Mark

Hello,

I am not aware of this issue, but I do about the link problem. The link above is for NI Internal Website. The Exteranl Website is this one:

I hope you can see this link this time.

Hi Mark,

I'm a test engineer trying to use an NI DIO 96 card in a 64 bit machine however the issue I am having is in the driver. I haven't been able to install the NIDAQ32.dll and was hoping that you might be able to lead me to where I could locate a 64 bit driver suitable for use with LabVIEW 2009. I see in the forum that you were having issues with the asssociated 32 or 64 bit slots and was hopin that you might have some ideas on the driver. Any help is appreciated.

Regards

You've hijacked a very old and unrelated thread.

The 64 bit driver for NI DAQ cards is DAQmx. Simply click on the support tab at the top of the page.
