USB Mode
1. Specify USB2000 in the Spectrometer Type
drop-down menu.
2. Specify USB2000 in the A/D Converter Type
drop-down menu.
3. Specify the serial number of the USB2000
under the USB Serial Number drop-down
menu.
Note: The system pre-fills this drop-down
menu with the serial numbers of all
discovered USB2000 Spectrometers.
4. Click the OK button to accept the selected
options.
Serial Port Mode
1. Select the USB2000 option from the
Spectrometer Type drop-down menu.
2. Select the Serial (RS-232) A/D option from the
A/D Converter Type drop-down menu. This
selection enables serial-specific options in the
lower portion of the Configure Hardware
screen.
3. Select the COM port that the USB2000 is
connected to in the Serial Port drop-down
menu. Consult Chapter 4: Troubleshooting for
information on identifying serial ports.
4. Select the speed at which the USB2000 will
operate from the Baud Rate drop-down menu
(115,200 baud is recommended).
5. Specify the pixel resolution (from 1 to 500) in
the Pixel Resolution box. This value specifies
that every nth pixel of the spectrometer will
transmit from the USB2000 to the PC.
Note: You can sacrifice pixel resolution to
gain speed. The transfer of one
complete spectra requires ~0.3
seconds at 115,200 baud.
6. Enable the Compress Data function to
minimize the amount of data transferred
over the RS-232 connection. The
transmission of spectral data over the serial
port is a relatively slow process. Enabling
this function ensures that the USB2000
compresses every scan that it transmits.
This greatly increases the data transfer
speed of the USB2000.
7. Click the OK button to complete setup.
The spectrometer should now be able to acquire data and respond to light. Exit and restart OOIBase32 to save
configuration data to disk.
