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.
