Two Ethernet cards at one time

Hello all

I have a problem someone may be able to help me with.

I wish to use LabVIEW to communicate down an Ethernet card to a test unit
no problem so far ) however I want to connect up to our LAN using Ethernet
and the I.T. boys say we can't have an untested unit on there network.

"OK" I say, we will use two network cards ( one to communicate to the
network and one to test the unit ) This is where my troubles begin.
LabVIEW will not let me use any other Ethernet card but the default card.

Does anybody know a work aroung?? I was thinking maybe using CIN but I will
have to write the code myself and haven't a clue where to start. Any
pointers would be greatly appreciated.

Thanks

What's the error that you get? I'd heard that this was in fact possible.

I have to admit I've never tried this but from my experience with LV I'd hazard
aguess that it's the underlying operating system that's the limiting factor
here. NT4 will allow multiple network cards and allow you to set the computer
up to be a virtual router/bridge. I got this working quite well on NT4 server,
albeit with a big performance hit on other tasks, a while back before removing
it. I think NT4 W/S has the same facility but I'm not 100% certain. Try looking
under 'Multiple NICs' in the help files or indexes of NT books. Once configured
LV should be able to see both cards (probably!)

Why not get your IT boys to help out instead of being IP [1] boys.

Hope this helps
