The NI GPIB-120A is a GPIB expander. IEEE 488.1 prescribes a maximum of 15 electrical device interface loads in a GPIB system. A GPIB-120A increases the maximum number of GPIB system devices from 15 to 28. It 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.

Note: The GPIB-120A is obsolete. NI recommends the GPIB-120B bus isolator and expander.
