The National Instruments GPIB-120A is a GPIB expander. IEEE 488.1 prescribes a maximum of 15 electrical device interface loads in a GPIB system. An NI GPIB-120A increases the maximum number of GPIB system devices from 15 to 28. The GPIB-120A is also useful in test and measurement systems because it provides an electrically isolated interface to one or more devices. The GPIB-120A is software transparent; you do not need to rewrite application software.
