Mount the two standoffs and the two socket head cap screws onto the main board. Use fourPhilips pan head screws to secure the gPIb card into the rear panel of the DSP7000.5. Replace the top cover of the DSP7000 and secure with four Philips pan head screws.8.2.2 aBouT THe gpiB inTerfaCe(general Purpose Interface bus)Magtrol instruments use the gPIb (IEEE-488 Standard) for computer-to-instrument interfacingbecause:• The GPIB parallel interface is faster than serial interfaces.• The GPIB enables testers to access up to 15 instruments on one port. Because typical motortesting requires that at least five separate parameters be synchronized, a system of easy, fastaccess to more than one instrument is essential.• The GPIB has rigid data formatting and hardware standards. These standards help to ensurethat all functions will work properly when the hardware and software are installed.Note: The gPIb interface is not standard on most computers. An interfacecard and driver software must be installed. An IEEE-488 cablemust also be installed between the computer and the DSP7000.Magtrol recommends National Instruments Corporation hardwareand software.
