The Ocean Optics high-speed ADC2000-PCI+ presents another
plug-and-play, analog to digital desktop PC interface option to users of
the popular Ocean Optics S2000 miniature fiber optic spectrometer. The ADC2000-PCI+ fits into
a desktop PC's PCI-bus slot and couples to any S2000
Spectrometer via a D37-pin to D25-pin interface cable that is provided
with each ADC2000-PCI+ unit.
The ADC2000-PCI+ features a channel rotator
function that permits simultaneous acquisition of pixels from up to 8
spectrometer channels. For example, the S2000
spectrometers can be configured with a master and slaves for a total of n
spectrometer channels. Pixel #0 is acquired from the
master channel while pixels #1 through # (n-1) are acquired in sequence
from the remaining channels. The acquisition sequence would repeat with
pixel n from the master channel. The benefit of the channel rotator
is that spectra from all channels can be gathered at precisely the same
time, making the ADC2000-PCI+ ideal for applications involving pulsed light
sources and transient spectral events. The data collected when using the
multi-channel scanning capability of the ADC2000-PCI+ can be separated into
individual spectra by a variety of Ocean Optics
software products.
ADC2000-PCI+ Technical Note
The
ADC2000-PCI+ provides 8 General Purpose Input/Output (GPIO) ports that can be
controlled individually at TTL levels through our OOIWinIP
driver development package. A custom cable with a DB-25 (male) connector
allows access to the GPIO. The
ADC2000-PCI+ is the only Ocean Optics A/D
converter that supports GPIO functionality.
