PECTROMETER has our 2048-element linear CCD-array fiber optic spectrometer mounted onto an ADC1000. This sturdy combination fits easily into a slot in the PC. The following are directions for installing your ADC1000 and PC2000. Because A/D converter installation goes handin-hand with software installation, you will find directions for installing OOIBase32 Spectrometer Operating

Software included in this section as well.

Each device in or connected to your computer is assigned specific settings; it’s similar to giving each device its own name so that your computer will know what to call and how to recognize the device. In order for your

ADC1000 or PC2000 to work as a device in your computer, it has to be assigned a Base Address setting and an

IRQ setting. The default settings for each are:

Base Address (I/O Range): 768 decimal (300 hexadecimal)

IRQ (Interrupt Request): 07

These default values are set on the A/D converter. There are dip switches on the A/D board and their positions determine the values. These default values are set in the operating software as well. Most of the time, these default settings will work with your computer. However, if you have many devices installed in your computer, you may have a conflict; other devices may be using these settings. If there is a conflict with another device in your computer, you must change the positions of the switches on the A/D board and change the values in the software.

For the ADC1000 and PC2000, there is only one bank of switches on the A/D board: the Base Address may be changed via the first 6 switches and the IRQ may be changed via the last 3 switches. To first check your computer to see which settings are available, follow the instructions for your Windows operating system.

Find Available Base Address and IRQ Settings

1.

Go to Start | Settings | Control Panel and double-click on the System icon.

2.

Choose the Device Manager tab and double-click on “Computer” at the top of the list.

3.

Under View Resources, find available settings -- numbers unassigned to hardware. Note these available settings for both the Interrupt request (IRQ) and the Input/output (Base Address). When you first run

OOIBase32, you must enter these values in the “Configure Hardware” dialog box. (Remember that

Input/output settings are expressed in hexadecimal.)

!

For most computers, the default settings work well. In the picture above left, it appears that the Printer occupies

IRQ 07, but for most computers, our A/D converters can share the 07 setting with a printer and conflicts will not arise. All computers have multiple Base Address (Input/output) settings from which to choose.

Installation Instructions: ADC1000 & PC2000 (for Windows 95/98 Users)

Install the ADC1000 (or PC2000)

1.

Turn off the computer and remove the computer cover.

2.

Ground yourself to the computer chassis or power supply and remove the A/D card from its static-shielded bag.

3.

If necessary, change the position of the switches on the A/D board. Position the switches to match the available settings you found in the previous section -- numbers not being used by other hardware devices. See pages 5 and 6 for switch setting positions.

4.

Find an open ISA-bus slot and remove the slot protector.

5.

Insert the A/D card into an available expansion slot on the motherboard by gently rocking the card into the slot.

Make sure the card is fully seated in the motherboard before screwing the tab on the A/D card to the computer.

Do not bend the card or move it from side to side once it is seated in the slot.

6.

For the ADC1000, attach the D37 end of the cable to the card and the D25 end to the spectrometer. For the

PC2000, attach the desired optical fiber to the SMA connector on the PC2000. Reinstall the cover.

Install OOIBase32

Before installing OOIBase32, make sure that no other applications are running.

1.

Execute Setup.exe. At the “Welcome” dialog box, click Next>.

2.

At the “Destination Location” dialog box, accept the default or choose Browse to pick a directory. Click Next>.

3.

At the “Backup Replaced Files” dialog box, select either Yes or No. We recommend selecting Yes. If you select

Yes, accept the default or choose Browse to pick a destination directory. Click Next>.

4.

Select a Program Manager Group. Click Next>. At the “Start Installation” dialog box, click Next>.

5.

Follow all prompts regarding the Spectrometer Configuration diskette that came with your system. For more on the Spectrometer Configuration diskette, see the Note below. (If you downloaded OOIBase32 from the Ocean

Optics web site, you will not have this diskette. Select No when first asked about the diskette.)

6.

At the “Installation Complete” dialog box, choose Finish>.

7.

When prompted to do so, restart your computer when the installation is complete.

Note:

In your spectrometer shipment box, you received a Wavelength Calibration Data Sheet wrapped around a floppy diskette. The Wavelength Calibration Data Sheet and the spectrometer configuration file on the floppy diskette contain the same information, which is unique to your spectrometer. When you install OOIBase32, you are prompted to insert this diskette into your computer so that this data is installed with the software. However, if the diskette is ever lost, or if you downloaded OOIBase32 from the our web site and did not receive a diskette, you can use the data on the Wavelength Calibration Data Sheet to enter into OOIBase32 fields. (If you need a copy of your Wavelength Calibration Data Sheet, contact Ocean Optics.)

Run OOIBase32

After you restart your computer, navigate to the OOIBase32 icon and select it. The first time you run OOIBase32 after installation, you must follow several prompts before you can begin taking measurements.

Operator and Serial Number Dialog Box

First, a prompt to enter a user name and serial number appears. Certain data files will include this information in the header. (If, at a later date, you wish to change the operator name and serial number, select Edit | Settings from the menu and then choose the Registration tab.) Click OK.

Default Spectrometer Configuration File

Next, the following message appears:

This appears to be the first time OOIBase32 has been executed. Please select a default spectrometer configuration file from the following screen. This spectrometer configuration file will be used each time OOIBase32 is started.

- 2 -

Installation Instructions: ADC1000 & PC2000 (for Windows 95/98 Users)

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 opens.

1.

Under Spectrometer Type, choose S2000/PC2000.

2.

Under A/D Converter Type, choose ADC1000/PC2000.

3.

Under Base Address, choose the same setting as the dip switches on the A/D board (and the same available setting you found in your computer).

Remember that the Input/output Range (Base Address) you selected was expressed in hexadecimal. In this dialog box, the base address is given in decimal, followed by the hexadecimal equivalent in parenthesis.

For example, “768 (0x0300)” gives the base address as

768 decimal and 300 hexadecimal.

4.

Under IRQ, choose the same setting as the dip switches on the A/D board (and the same available setting you found in your computer).

5.

For your setup, only these parameters apply. (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

. 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.)

In the Wavelength Calibration page, the

" coefficients for each spectrometer channel in your system have already been loaded as part of the spectrometer configuration file that came on a floppy diskette with your spectrometer. (See the Note on page 2.) If you did not receive this floppy diskette, you can enter the wavelength coefficients of your system from the

Wavelength Calibration Data Sheet that came with your spectrometer. Check the Enabled box for each spectrometer channel in your system.

In the A/D Interface page, enter the same values as you did in the Configure Hardware dialog box.

" The Detector Linearity page in this dialog box allows you to enter coefficients for an algorthim that corrects for rare occurances of non-linearity of the detector. Contact Ocean Optics for more information.

Save the spectrometer configuration file by choosing Spectrometer | Save Configuration As from the OOIBase32 menu. You can rename the file or use the default file name ( [your serial number].spec

). You will then be asked if you would like to make this file the default spectrometer configuration file. Choose Yes. The next time you run

OOIBase32, the software will use the file as the standard for your spectrometer configuration. When you exit

OOIBase32, any changes to the configuration file will be automatically saved to the default file.

OOIBase32 Settings Dialog Box

At this point, it is a good idea to configure several OOIBase32 operation parameters. Choose Edit | Settings from the menu to open the OOIBase32 Settings dialog box. Go through each page of this dialog box to select options for saving, opening, and printing data; to configure default setting files; and to select other important options such as storing and copying data and choosing warning messages. (See the OOIBase32 Spectrometer Operating

Software Manual for details.)

Configure Data Acquisition Dialog Box

Finally, select Spectrum | Configure Data Acquisition from the menu to set your data acquisition parameters in the Configure Data Acquisition dialog box. The Basic page allows you to set the integration time and choose averaging and boxcar smoothing values. The External Trigger page allows you to specify the external trigger mode. The Strobe page allows you to control external strobe events with the spectrometer. (See the OOIBase32

Spectrometer Operating Software Manual for details.)

Changing the Base Address Settings for the ADC1000 and PC2000

To change the Base Address settings on the ADC1000 and PC2000, see the bank of switches on the A/D board:

The Base Address may be changed via the first 6 switches (the IRQ may be changed via the last 3 switches).

Switches in the OFF position have the decimal values shown. Switches in the ON position have a value of zero.

The Base Address is the sum of the values of the switches. In the default setting, switches 5 and 6 are added to give a total of 768. A few of the many combinations for Base Address settings are below. After you have changed the switches, reinstall the card and change the software settings to match the hardware settings. (See pages 1-4 for instructions.) The gray block indicates the position of the switch.
