Problem Possible Cause Suggested Solution
At startup, the device’s controls
appear disabled, no values
display, or the device shows
other signs of not uploading
data.
The NeoFox drivers and
firmware versions are
incompatible. Update the NeoFox firmware and
NeoFox Viewer software. See
Updating Software for more
information.
During hardware installation,
the Found New Hardware
Wizard” can’t find the driver or
.sys file for the NeoFox.
The NeoFox directory isn’t
included in search.
When prompted, choose to install
from a specific location, then include
the NeoFox installation directory in
your search. This directory is located
at “C:\Program Files\Ocean
Optics\
Neofox Viewer” by default.
The drivers can be found in the USB
Drivers directory located here.
After running a VI that calls the
Neofox DLL, LabView crashes
when that VI is closed. The VI passes a function in
the library an uninitialized
string. The library functions generally
assume that any strings passed are
already initialized. Therefore, be
sure to pass only initialized strings.
Better error handling for this error
was added in DLL version 1.89, but
you should still use this convention
to avoid unnecessary complications.
After setting the display units to
anything other than ppm, the
display will not return to percent
oxygen. Previous software version. This problem was resolved in
version 1.92 of the Neofox Viewer.
Contact Ocean Optics if you see this
error in a more recent software
version. Previously, this problem
was solved by reinstalling the
NeoFox Viewer software.
Percent oxygen is above 100 or
below 0. Sensor probe has been
calibrated incorrectly. Recalibrate the sensor probe.
A fatal error or critical error
warning message appears at
startup and prompts to continue
or exit the application. After
continuing, the FFT view does
not seem to work. This problem seems to occur
when the application starts
with the FFT View Window
active. Select Continue, then select the
waveform or decay form view. Close
the application and then restart. The
problem should not occur again. If
the problem persists, reinstall the
NeoFox Viewer software.
