PCI 5V

[cig438]

I have a computer with standard 33MHz PCI slots. They support 5V cards
only. Will the PCI-6221 work - is it a 5V or 3.3V or universal card ?
I couldn't find any info on this in the manual.

Thanks,

Hello,
You should browse the <a href="http://www.ni.com/pdf/manuals/371290f.pdf" target="_blank">NI 622x specifications</a> document. It indicates that power is drawn from the 3.3 bus,&nbsp;except for the NI-6221 (37 pins) that doesn't use 3.3V from the bus.
Regards,

It seems that power is drawn from 3.3, 5, &amp; 12V. It looks like these are standard voltages supplied by the PCI bus.
Seems like the 6221 needs all 3 voltages ?
I guess my classification of PCI cards : 5V, 3.3V, or universal&nbsp;&nbsp; - is wrong ?
How can 33MHz PCI cards be properly classified, &amp; does each type have a different mechanical identation of the pinouts ?
