Magtrol instruments use the GPIB (IEEE-488 Standard) for computer-to-instrument interfacing
because:
• TheGPIBparallelinterfaceisfasterthanserialinterfaces.
• TheGPIBenablestesterstoaccessupto15instrumentsononeport.Becausetypicalmotor
testing requires that at least five separate parameters be synchronized, a system of easy, fast
access to more than one instrument is essential.
• TheGPIBhasrigiddataformattingandhardwarestandards.Thesestandardshelptoensure
that all functions will work properly when the hardware and software are installed.
Note: The GPIB interface is not standard on most computers. An interface
card and driver software must be installed. An IEEE-488 cable
must also be installed between the computer and the DSP7000.
Magtrol recommends National Instruments Corporation hardware
and software.
