First you have to go through NI-488.2 getting wizard from the National instruments start menu
verify your hardware and software installations procedures and go through Measurement & Automation Explorer(MAX) and try to set the address 1 in the instrument as well as MAX, communicate with the instrument.
If the above soln. doesn't work, pl. uninstall the card and install in another slot, if stll there is a problem, uninstall MAX, DAQ, labview and install aqain
then you can start using the instrument with labview using some examples from the GPIB section to write and read, make sure to give enough time-out 3600, and mode as 3 for example
you can download the command set used http://www.axiomtek.net.cn/images/datasheets/AX4810P.pd
