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. You must specify your hardware
configuration in this dialog box.
1. Under Spectrometer Type, choose S1024DW.
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 on page 6 for help in determining the COM Port number.

4. Under Baud Rate, select the speed at which the SAD500 will operate.
5. Under SAD Pixel Resolution, enter resolution values from 1 to 500. This value specifies that every

pixel of the spectrometer is transmitted from the SAD500 to the PC. Your resolution value

depends on your experiment. By sacrificing pixel resolution, you gain speed. The transfer of one
complete spectra requires ~0.3 seconds when communicating at 115,200 baud rate. If you need your
information in <0.6 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 insures 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; the driver will

only read settings that pertain to the spectrometer and A/D converter you have chosen.) 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 when you start OOIBase32, exit OOIBase32 by
selecting File | Exit. Then select Start | Run, and type

C:\windows\ooidrv.ini

. Notepad will

open. Edit the initialization 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. (For detailed information on each page of this dialog box, see the

OOIBase32 Spectrometer

Operating Software Manual

or the software’s help files.)
