5. Computer Controlled Operation
The 6200 can be used with a personal computer to control a dynamometer and to transmit data
from motor testing directly to the computer.
5.1
about the gpib interfaCe
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 must 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. Magtrol recommends
National Instruments Corporation hardware and software.
• An IEEE-488 cable must be installed between the computer and the 6200.
