how can i read 2 different 8 bit encoders using one daq card, using labview 7?

[dharte]

need to write code to be able to differentiate between the two encoders

Have you checked out the Application Note on encoders?

There are some good Knowledgebase articles too. The code will depend on which DAQ board you have and what type of encoders you're using.
