PCMCIA-GPIB for OS X?

Any suggestions for communicating with a PCMCIA-GPIB card under Mac OS X?  Does NI have any plans to add PCMCIA support to the OS X GPIB driver?  (OS 9 is not available.)

Right now we currently don't have plans to add support for PCMCIA-GPIB to the OS X driver.  Right now we have had little customer interest in PCMCIA-GPIB support for OS X.  However, R&D is keeping a close watch on customer requests for OS X drivers so that they can get a better feel for where their resources are needed.  I've made R&D aware of your request.

If you don't mind me asking, why did you choose to inquire about PCMCIA instead of USB.  There are no definite plans as of yet to add GPIB-USB support, but R&D would like to know which of these interfaces is prefered.  It seems right now that USB is becoming the preferred bus for MAC, but I just wanted to get your perspective on this.

Thanks for you interest and you input,

Thanks for the reply.  I wouldn't say I'm a compelling case to base a support decision on; I'm just wondering what the future might hold.

I'm asking because I just joined a lab that already has a large number of PCMCIA-GPIB cards, and I came in with a Mac notebook.  Since that's the machine where I have all my notes, Mathematica, Matlab, and so forth, it would have been vaguely convenient not to have to migrate or muck about transferring data from another machine.  (There's no dedicated desktop host for the instruments here; people use notebooks to talk to whatever they're using at the time.)  I suspect that if they buy more GPIB cards, they'll probably be USB rather than PCMCIA, but there's not a lot of interest in replacing hardware that's generally seen to work perfectly well.  In the end, it's not an insurmountable problem; I'll borrow a Windows machine and transfer data.

Actually, another pie-in-the-sky question: are specs for those cards available that would allow someone to write a third-party driver, or are those kept confidential because the drivers are an NI product?

Best,
Mike

Hi Mike,

Thanks for the information.  It really helps us to hear about use cases such as yours so that we can get a more complete picture of how our products are used.

We also provide another driver called NI-Device that allows you to take one of our GPIB devices and create your own talker/listener interface.  NI-Device does support the PCMCIA-GPIB and is also available in a DDK.

 

I hope this helps you out.  Have a great day!

NI-Device does not support controller operations, so it would not likely suit your needs.  We do offer the NI-488DDK, but it is likely that this solution would be a bit expensive for you.  I would estimate that it isn't likely that we'd add support for PCMCIA anytime soon.  If anything, we have to prioritize x86 support for MacOS X, but we do not as of yet have a schedule for that.

Concerning the question of which bus would be popular with Macintosh users: on the laptops I would guess USB. My PowerBook (a couple of years old) has ethernet, USB and Firewire interfaces so for me it has to be one of these. The ethernet connection is normally in use for our LAN, and I don't like connecting instruments to external networks, so that leaves the USB or Firewire interfaces for instrument control. PCs don't generally have a Firewire interface, so a USB-GPIB adapter should be usable with anybody's laptop. If only GPIB-USB was supported for Mac OSX...
Many of the hardware people here (we design and build planetary science instruments for spacecraft) have switched to Macintosh laptops because they prefer the UNIX-like development environment to that available on a default-equipped Windows machine.
