Need help with Hardware setup?

[gaulin@mailandnews.com]

I have three inputs to coordinate in labview and they are all serial
R232. What is the best/cheapest way to input these into my system? Is
there a serial switching box I need or should I get an expansion card?
Thanks.

By default each port needs its own IRQ. They begin with IRQ4 and IRQ3,
and the third IRQ is not predefined (the third port should be 0x3e8).
If you can get an RS232 card on which you can jumper a free IRQ and port
0x3e8, then you can work with three COMs.

Viele Gruesse!

You can get a variety of serial cards from National Instruments in both RS232
and RS485. These cards come in 2, 4, 8 and 16 port arrangements and you can
have over 100 serial ports on one computer. If you get a card from National
Instruments it will work perfectly with Labview with ease. I have used many
of these cards with success.
