8. Computer Controlled Operation
The DSP6001 can be used with a computer to control a dynamometer and to transmit data from the
motor testing device directly to the computer. Using the DSP6001 with a computer enables the unit
to perform at its full capacity.

ABOUT THE GPIB INTERFACE
(General Purpose Interface Bus)
Magtrol instruments use the GPIB (IEEE-488 Standard) for computer-to-instrument interfacing
because:
• The GPIB parallel interface is faster than serial interfaces.
• The GPIB enables testers to access up to 15 instruments on one port. Because typical motor
testing requires that at least five separate parameters be synchronized, a system of easy, fast
access to more than one instrument is essential.
• The GPIB has rigid data formatting and hardware standards. These standards help to ensure
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 DSP6001.
Magtrol recommends National Instruments Corporation hardware
and software.
