Connecting the MC-III to a Computer
Before attempting to run the interface software, verify that the Scanner is connected to a computer with an
RS-485 to RS-232 converter or an RS-485 to USB converter.
• See
Figure 2.17, page 27,
for converter wiring instructions.
• See
Explosion-Proof Communications Adapter, page A-3,
for instructions on installing and wiring an RS-
485 communications adapter.
• See
USB Communications Adapter, page A-6,
for instructions on installing and wiring the USB commu-
nications adapter. A USB driver supplied on the MC-III software installation CD must be installed on
the computer before the USB adapter will be operational. A customer-supplied universal USB cable is
required to connect the NuFlo USB adapter to a computer.
Running the Software
Once the software is installed and the computer is connected to the MC-III, the user may proceed with
running the software and configuring the device.
To connect to the MC-III device via software, perform the following steps:
1.
Click on the NuFlo MC-III icon on the desktop, or select Start>Programs>NuFlo>MC-III 2.1.0>MC-III
2.1.0 . The Welcome screen (Figure 4.2) will appear and a Select COM Port window will prompt the user
to select the communications port to be used to connect with the MC-III EXP (Figure 4.2).
2. Select a port from the dropdown list and click “OK.” If the NuFlo™ USB communications adapter is in
use, the COM port will appear as “NuFlo USB Adapter.” The software will attempt to connect with the
MC-III EXP. This automatic launch feature is referred to as an “express connect.”
3. If the internal time and date programmed into the instrument differs from the time and date displayed on
the computer by more than 60 seconds, the software will prompt the user to synchronize the instrument
time/date to match the computer time/date (
Figure 4.3, page 43
). This ensures that the instrument displays
correct time, regardless of time zone differences.
