The DSP6000 can be used with a computer to control a
dynamometer and to transmit data from motor testing
directly to the computer. Using the DSP6000 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. Magtrol

hardware and software.
• An IEEE-488 cable must also be installed
between the computer and the DSP6000.

INSTALLING THE GPIB (IEEE-488) CONNECTOR
CABLE
Make sure both the computer and the
DSP6000 are turned OFF before
installing the GPIB connector cable.
1. Connect one end of a high-quality, double-shielded
cable to the DSP6000 GPIB connector.
2. Connect the other end to the GPIB interface in your
PC.
CHANGING THE GPIB PRIMARY ADDRESS
Each instrument serviced by the GPIB has its own
Primary Address code, which enables the computer to
obtain readings from the instrument. The factory default
setting on the DSP6000 is 09.
