RE: Two Ethernet cards on one PC

Hello All

some one mailed me a message requiring a problem we had a while ago about
two Ethernet cards on one PC. Unfortunately I accidentally deleted the
message before responding to it, so if I post the answer here maybe they
will see it.

We got two Ethernet cards to work with LabVIEW by giving them different
address. I.E. Card 1 had address 123.456.FFF.001 and card two had
234.567.FFF.001. Card one was connected to the network and card 2 was
connected to the unit we wanted to test. We think that LabVIEW uses the
address to determine which card is being used. Anything connected to card 1
must be on the same domain in order for it to work I.E. 123.456.XXX.XXX
where X = any hex number from 1 to F )( the same for card 2 )
We didn't
test this theory, but our system is working and it is the best explanation I
can come up with.

You are right except that it is NT that is figuring out which to use base on the
ip you are addressing. It has the bindings and their priority in the network
set up. We use two cards, one for the company network and another that is a
local connection to the unit under test. No problems at all with NT.
