Appendix C: Frequently Asked Questions
What is the 750 USB Interface?
The 750 USB interface was developed to meet the needs of those users
who prefer the USB connection (or those whose computers do not
support SCSI connections).
The PASCO 750 SCSI interface uses a SCSI (Small Computer System
Interface) port to communicate with the PC or MacIntosh (Mac)
computer to which it is connected. The SCSI-equipped interface is
now known as the “750 SCSI interface.”
Are there other differences between the 750 SCSI and the 750
USB?
No. The 750 USB is identical to the 750 SCSI in all respects, except
for the communications port. The 750 USB uses all the same sensors
and performs the same functions as the 750 SCSI. The overall rate at
which data is transmitted to the Mac or PC is essentially the same. The
750 USB Interface only works with DataStudio software; this differs
from the 750 SCSI interface, which is compatible with the older
ScienceWorkshop
software.
How do I know if my computer has a USB port or a SCSI port?
If your computer has a USB port, you will see the USB symbol
embossed, engraved, or printed next to the port on the back of your
computer. If you purchased a computer that was manufactured in 2001
or 2002, chances are you have a USB-compatible computer.
A SCSI port works with a serial 50-pin connector cable and often
requires a SCSI card.
If you are still unsure about the type of port your computer has, check
the documentation that came with your computer or call the
manufacturer.
My computer has two USB ports. Can I connect and use two 750
USB Interfaces at the same time?
You can connect two 750 USB Interfaces, but only one interface will
be recognized by DataStudio. The interface that is recognized first will
