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.
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.
Using the ADC1000-USB: USB Mode 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.
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.
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.
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.
Using the ADC1000-USB: USB Mode Configuring Data Acquisition Select Spectrum > Configure Data Acquisition from the OOIBase32 menu bar to open the Configure Data Acquisition screen. From this screen, you can configure your data acquisition parameters such as integration time, averaging, boxcar smoothing, and several other parameters.
Using the ADC1000-USB: USB Mode 3. Select the Wavelength Calibration tab. 4. Enter in the values you acquired from Steps 5-6 in the Calibrating the Wavelength of the Spectrometer section. 5. Click on the Write to ADC1000USB button, then click the OK button.
Using the ADC1000-USB: Serial Mode Serial Port Overview Interface the ADC1000-USB to the Spectrometer If you ordered your S2000 or S1024DW 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 interface the ADC1000-USB to the back of the spectrometer.
Using the ADC1000-USB: Serial Mode Install the OOIBase32 Software Consult your OOIBase32 documentation for instructions on installing OOIBase32. Configure the OOIBase32 Software – Serial 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 website.
Using the ADC1000-USB: Serial Mode 7. Enter a value from 1-500 in the Pixel Resolution text box. This value specifies that every nth pixel of the spectrometer will transmit from the ADC1000-USB to the PC. Sacrificing resolution equates to an increase in speed. The transfer of one complete spectra requires approximately 0.3 seconds at 115,200 baud. If you need information more frequently than 0.3 seconds per spectra, increase the resolution or enable data compression (see Step 8). 8.
Using the ADC1000-USB: Serial Mode 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: A/D Interface Tab Enter the same values as you did in the Configure Hardware dialog box (see the Configure the OOIBase32 Software – Serial Port section for more information).
Using the ADC1000-USB: Serial Mode 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 .
Using the ADC1000-USB: Serial Mode Saving Wavelength Calibration Coefficients: Serial Mode If you are interfacing the S2000 Spectrometer or S1024DW Spectrometer to your PC via the serial cable, you need to save the wavelength calibration coefficients to the .spec file that OOIBase32 accesses each time it opens. Note: You cannot save the calibration coefficients to the EEPROM memory chip on the ADC1000-USB when using the serial mode. To save wavelength calibration coefficients using the serial mode: 1.
Using the ADC1000-USB: Serial Mode ADC1000-USB-S Notes The ADC1000-USB-S does not function any differently from the ADC1000-USB. However, there are configuration notes specific to the ADC1000-USB-S that you must follow when using the ADC1000-USB-S.
Troubleshooting 3 Troubleshooting The following sections contain information on resolving some of the most common problems encountered when using the ADC1000-USB: Troubleshooting Device Driver Installation Issue: After connecting the ADC1000-USB to the PC, the Add New Hardware Wizard does not locate a device driver for the ADC1000-USB. Ultimately, a message appears stating that Windows has not installed a device driver.
Troubleshooting (Remove Unknown Device from Device Manager Continued) 2. Locate the Other Devices option and expand the Other Devices selection by clicking on the "+" sign to the immediate left. Note: Improperly installed USB devices may also appear under the Universal Serial Bus Controller option. Be sure to check this location if you cannot locate the unknown device. 3. Locate the unknown device (marked with a large question mark).
Troubleshooting (Remove Improperly Installed Files Continued) Windows 2000: 1. Open Windows Explorer. 2. Navigate to the Windows | INF directory. If the INF directory is not visible, you will need to disable the “Hide System Files and Folders” option on in Windows Folder Options. Note: If the INF directory is not visible, you will need to disable the “Hide System Files and Folders” and “Hide File Extensions for Known File Types” options in Windows Folder Options.
Troubleshooting An Older Version of OOIBase32 is Installed on the PC Issue: The PC you wish to use with the ADC1000-USB has an older version of OOIBase32 installed on it. Probable Cause: Not applicable. Resolution: Install the latest version of OOIBase32 from the Software and Technical Resources CD. Alternately, you can download the latest version from the Ocean Optics website at the following address: http://www.oceanoptics.com/technical/softwaredownloads.
Troubleshooting Serial Port Number is Unclear Issue: The serial port used by the ADC1000-USB is unclear, or the serial ports on the PC are not numbered.
