NI-488.2 OverviewThe NI-488.2 softwarefor Mac OS is a compreh ensive setof programs
and drivers.It sim plifies the job of programming the GPIB-ENET/100 to
function as an IEEE 488.2 (GPIB) Controller with complete
communication and bus management capabilities.
NI-488.2 also includes a GPIB interactivecontrol utility; the Macintosh
Programmer’s Workshop (MPW) C, THINK C, and Metrowerks
CodeWarriorC languageinterfaces; and a shared library for

testsand w hen acquiring networkparameters.
A steady yellowstate indicates the box is ready
foroperation. Slow flashing pattern indicates an
error occurred.
