Figure 2-1 and Figure 2-2 show typical applications for the GPIB-1014P. In Figure 2-2, the
GPIB-1014P is used to interface an assortment of test instruments to a VMEbus computer
system, which then functions as an intelligent System Controller. This is the traditional role of the
GPIB.
In Figure 2-2, the GPIB-1014P is used along with other National Instruments interface boards to
connect a VMEbus computer to other processors in order to transfer information or to perform
other communication functions.
