Configuring the Ocean SR2
The Ocean SR2 can be used with OceanView software when connected to the USB port. If you have followed the previous steps and
started your spectroscopy application, the spectrometer is already acquiring data. Even with no light in the spectrometer, there
should be a dynamic trace displayed in the bottom of the graph. If you allow light into the spectrometer, the graph trace should rise
with increasing light intensity. This means the software and hardware are correctly installed.
Hardware Setup
The Ocean SR2 Spectrometer connects to a computer via the USB port. When connected through a USB 2.0 or 1.1 port, the
spectrometer draws power from the host computer, eliminating the need for an external power supply
Follow the steps below to connect the OCEAN SR2 to a computer via the USB port:
1. Install the spectrometer operating software on the
destination computer.
2. Locate the USB cable (USB-Cable) provided with
the Ocean SR2.
3. Insert the micro connector end of the cable into
the side of the Ocean SR2 and the larger end of
the cable into the USB port of the computer.
4. Connect any spectroscopy accessories. To find
operating instructions for Ocean SR2-compatible
products (such as light sources, sampling
chambers, and probes), consult the Ocean Insight
website at OceanInsight.com.
5. Attach the fiber to the fiber optic connector on the
spectrometer.
If you installed the spectrometer operating software prior to connecting the Ocean SR2, the software automatically installs the
correct drivers. If the drivers do not successfully install (or if you connected the Ocean SR2 to the computer before installing the
software), consult Troubleshooting.

1 Dynamic range for a single acquisition is a measure of the ratio of full signal to noise.
2 Dynamic range of the system is the range of the detectable light level and can be thought of as the maximum detectable light level at
the minimum integration time divided by the minimum detectable light level at the maximum integration time.
3 Scan rate is dependent on factors external to the spectrometer. This figure was obtained using OmniDriver and OceanDirect APIs.
