ADC1000-USB Overview

1 Overview

The ADC1000-USB External USB A/D Converter is a plug-and-play high-speed analog-to-digital
(A/D) converter designed for hassle-free instrument-to-PC interfacing. An A/D converter is
necessary to interface all Ocean Optics spectrometers to PCs.

Interface Options

The ADC1000-USB can interface to external devices via the USB port or the Serial port. The
following table details requirements for external devices:

ADC1000-USB Overview

USB Port

The ADC1000-USB interfaces an S2000 Spectrometer to a notebook or desktop PC via a USB
port. When interfaced to a PC via the USB port, the ADC1000-USB does not require an external
power supply -- it draws its power from the PC to which it is connected.

The ADC1000-USB can connect via the USB port to any PC that uses a Windows
98/Me/2000/XP operating system and has OOIBase32 installed and configured for use with your
ADC1000-USB. If multiple PCs meet these two qualifications, you can switch your ADC1000-USB
and spectrometer among them.

The ADC1000-USB connects to the back of an S2000 Spectrometer and

interfaces to a notebook computer via the USB port and USB cable.

Serial Port

The ADC1000-USB also has a serial port for interfacing the S2000 or S1024DW Spectrometer to
PCs, PLCs and other devices that support the RS-232 communication protocol.

2 Using the ADC1000-USB

The following sections provide instruction on configuring and using the ADC1000-USB via the
USB port:

USB Port Overview

Note: To use the USB port on the ADC1000-USB, the PC to which you are connecting must run

either the Windows 98, Windows ME, Windows 2000, or Windows XP operating systems.

USB connectivity is not available on Windows 95 or Windows NT systems.

Interface the ADC1000-USB to the Spectrometer

If you ordered your S2000 Spectrometer and ADC1000-USB A/D Converter at the same time, the
spectrometer and the A/D converter should share one housing (see the ADC1000-USB-S Notes
section in this chapter). However, if you already owned a spectrometer and then purchased the
ADC1000-USB separately, you must connect the ADC1000-USB to the back of the spectrometer.
The picture below illustrates this connection:

Note: Do not connect the ADC1000-USB to the PC at this time. You must install the

OOIBase32 software first. If you connected the ADC1000-USB to your PC before you
installed OOIBase32, you will NOT be able to use your spectrometer. See the
Troubleshooting section for more information.

ADC1000-USB Operating Instructions 3

S2000 Spectrometer ADC1000-USB

Using the ADC1000-USB: USB Mode

Install the OOIBase32 Software

Consult your OOIBase32 documentation for instructions on installing OOIBase32.

Connect the ADC1000-USB to your USB Port

The USB port on the PC will supply sufficient power to the ADC1000-USB only if the ADC1000­USB is connected to 5 or fewer spectrometer channels. If the ADC1000-USB is connected to
more than 5 spectrometer channels, you will need an external power supply

Follow the steps below to connect the ADC1000-USB to the computer:

1. Locate the USB cable packaged with the ADC1000-USB.

2. Insert the square end of the cable into the side of the ADC1000-USB. Insert the flat
rectangular end of the cable into a USB port on your PC.

If you installed OOIBase32 correctly, the Add New Hardware Wizard message appears. The
driver (provided during the OOIBase32 installation) should automatically install.

Note: Wait 5-10 seconds between connecting the ADC1000-USB to the computer and starting

the OOIBase32 software.

Configure the OOIBase32 Software – USB Port

You will need to configure OOIBase32 before using the ADC1000-USB and your spectrometer.
For details on using OOIBase32, consult the OOIBase32 Spectrometer Operating Software
Manual, which can be found on the Software and Technical Resources CD and the Ocean Optics
web site.

The following steps provide instruction on starting and configuring the OOIBase32 software with
the ADC1000-USB:

1. Select Start > Programs > Ocean Optics > OOIBase32 and click on the OOIBase32
icon. If you are configuring OOIBase32 for the first time, the Configure Hardware screen
appears:

Using the ADC1000-USB: USB Mode

2. Select S2000/PC2000/USB2000/HR2000 from the Spectrometer Type drop-down menu.
Select ADC1000-USB from the A/D Converter Type drop-down menu. Select your
ADC1000-USB from the USB Serial Number drop-down menu. Then, click the OK
button. The User Name and Serial Number screen appears.

3. Enter a user name and software serial number, and then click the Next button. The
Select Default Spectrometer Message appears:

4. Click the OK button. The Default Spectrometer Configuration screen appears.

5. Go to the OOIBase32 installation directory and select the file named XXX.spec, where
XXX represents the serial number of your ADC1000-USB. Then, click the OK button.

Note: You will typically only set the parameters in this screen once -- when OOIBase32

is first installed and the software first opens. However, you can access this
configuration screen at any time by selecting Configure > Hardware from the
menu bar.

The system should now be configured to acquire data and respond to light. If you encounter
problems, exit and restart the OOIBase32 program.

Configuring the Spectrometer

The following section provides information on configuring your spectrometer and setting system
parameters:

Open the Spectrometer Configuration Screen

Select Spectrometer > Configure from the menu bar. The Spectrometer Configuration screen
appears:

ADC1000-USB Operating Instructions 5

Using the ADC1000-USB: USB Mode

Wavelength Calibration Tab

If your spectrometer and ADC1000-USB were packaged together, the displayed coefficients are
read from a memory chip on the ADC1000-USB.

The numbers in the Wavelength Calibration tab must match the coefficients from the Wavelength
Calibration Data Sheet that came with your spectrometer. If these numbers differ, copy the
coefficients that are on the floppy diskette that you received with your spectrometer to your hard
drive, or manually enter the values from the Wavelength Calibration Data Sheet and click the

Write to ADC1000USB button.
Note: You can also update the Wavelength Calibration Coefficients using the USB

Programmer.

A/D Interface Tab

Enter the same values as you did in the Configure Hardware dialog box (see the Configure the
OOIBase32 Software – USB Port section for more information).

When you exit OOIBase32, this data is stored in the .spec file.

Setting OOIBase32 Parameters

Select Edit > Settings from the OOIBase32 menu bar to open the OOIBase32 Settings screen.
From this screen, you can configure the following items:

• Configure options for saving, opening, and printing data

• Associate .WAV sounds with various program events

• Configure default-setting files

• Store data

• Copy data

• Configure warning messages
