The evaluation board and manual is intended to be used for a talker/listener, not a controller. However, National Instruments sells talker/listener/controller cards and drivers (see http://www.ni.com/support/gpib/versions.htm).
We sell a Driver Development Kit for developing drivers for some of these cards (P/N 777430-01), if they do not already exist for your platform. For more information on this product see ni.com/catalog.
