3-3. Installing Device Driver
Normally, device drivers for supported spectrometers will be installed with SEC Spectra as part of the
setup process. The device is usually displayed as "Taurus" in Device Manager (Figure 3-6).
Figure 3-6. Taurus is displayed correctly in Device Manager
The driver may not be installed due to unexpected errors. Figure 3-7 shows an example when the
device is not recognized correctly. It will be recognized as a device called "SCAN" with a "!" mark.
