Hi Cosmin,
this is some very old hardware…
Did you try to search the web for your hardware? When using Google to look for "pci-6070" it brings me (as first result) to the datasheet found at NI.com. And there you find a link to accessories…
Did you try to call NI sales for support?
Best regards,
GerdW
