Appendix A MC-III™ EXP Flow Analyzer
USB Communications Adapter
The NuFlo™ USB Adapter (Figure A.7) allows a user to connect a computer to the MC-III using a standard
off-the-shelf USB connector cable for quick and easy downloads without opening the MC-III enclosure.
Caution: This adapter is CSA-approved for use in hazardous areas. It does not have ATEX/IECEX
approval.
The USB adapter is comprised of a USB adapter socket, a blanking plug, and a union nut (Figure A.8). A CD
includes the software for installing the driver.
When the USB connection is ordered with an MC-III, the USB adapter is pre-installed at the factory. No
eld wiring is required. If the USB adapter is purchased as a kit, see Adapter Kit Installation, page A-7, for
installation instructions.
Important: Do not connect the USB adapter to a computer until a USB driver is installed using the
CD provided. MC-III software cannot connect to an MC-III without these les. See Using
the Adapter, page A-7.
