Multiple PCMCIA Cards

[Lik_Yeung]

My system requirement, I need 16 16-bit Analog Input Channel, and 2-Analog Output Channels. However, there are no such product existing in the form of PCMCIA.

Can I have a 12-bit DAQCard with 2 analog output, working together with another 16-bit DAQCard with just the 16-bit analog input? Will they be able to communicate to each other?

Is the alternative Option of the 16-bit DAQCard with another PCMCIA 2-channel analog output card be feasible?

Lik;

You are right when you say NI doesn't have a 16 bit PCMCIA card.
The best way to do what you need is by having 2 PCMCIA boards on your LapTop and having the same signal to trigger both Analog Input and Analog Output on the different cards. So, you can have maybe a digital signal which will trigger both operations at the same time. You can refer to the Application Note named "Advanced Synchronization Techniques for Data Acquisition" (you can find on our web site) to a good inside on how to sincrhonize operations.
Hope this helps.

Another option is to look into using a Magma Portable PCI Expansion system. Their CardBus-->PCI interface will allow you to purchase a 16-bit PCI board and use it in conjunction with your laptop. Their website is: www.magma.com
