Default Spectrometer Configuration File
Next, the following message appears:
This appears to be the first time OOIBase32 has been executed. Please select a spectrometer configuration
file from the following screen. This spectrometer configuration file will be used each time OOIBase32 is started.
A file open dialog box then appears. Navigate to the OOIBase32 directory, and choose the default spectrometer
configuration file -- the file with .spec as the extension, preceded by the serial number of your spectrometer. (A
default spectrometer configuration file will be named something similar to
I2J613.spec .)
Configure Hardware Dialog Box
Next, the Configure Hardware dialog box opens. The parameters in this dialog box are usually set only once -- when
OOIBase32 is first installed and the software first runs.
1.
Under Spectrometer Type, choose your
spectrometer.
2. Under A/D Converter Type, choose SAD500.
3. Under Serial Port, choose the COM port number
your computer is using to interface to your
SAD500. See the Troubleshooting section to
determine the COM Port.
4. Under Baud Rate, select the speed at which the
SAD500 will operate. (We recommend using
115,200 baud rate.)
5. Under SAD Pixel Resolution, enter resolution
values from 1 to 500. This value specifies that
every n
th pixel of the spectrometer is transmitted
from the SAD500 to the PC. Your resolution
value depends on your experiment. By
sacrificing resolution, you gain speed. The
transfer of one complete spectra requires ~0.4
seconds when communicating at 115,200 baud
rate. If you need your information in <0.4
seconds, increase the resolution or enable data
compression (see below).
6. Enable the Compress SAD500 Data function to
minimize the amount of data transferred over the RS-232 connection. Transmission of spectral data over the
serial port is a relatively slow process. Enabling this function ensures that every scan transmitted by the
SAD500 will be compressed, greatly increasing the data transfer speed of the SAD500.
7. For your setup, only these parameters apply to your system. (Ignore the other settings; they apply to other A/D
converters.) Click OK. You can always change these settings once OOIBase32 is fully operational by selecting
Spectrometer | Configure | A/D Interface.

If you do not see the “Configure Hardware” screen, exit the software. Then select Start | Run, and type
C:\windows\ooidrv.ini for Windows 95/98 systems or c:\winnt\ooidrv.ini for Windows NT
systems. Notepad will open. Edit this file for our device driver by finding the “Initialized” entry and making
sure this line reads
Initialized=0 . Save the OOIDRV.INI file and exit Notepad. Restart OOIBase32. You
should now see the “Configure Hardware” dialog box.
Spectrometer Configuration Dialog Box
Now that OOIBase32 is running, you need to configure your system. Select Spectrometer | Configure from the
menu. Go through each page in the Spectrometer Configuration dialog box to set system parameters. (See the
OOIBase32 Spectrometer Operating Software Manual for details.)
