Page 10: Installation And Setup
If you do not install the software first, the system will not properly recognize the spectrometer. If you have already installed the OCEAN SR2 to a computer running on a Windows platform prior to installing the operating software, consult the Troubleshooting section for information on correcting a corrupt OCEAN SR2 installation. -
Page 11: Configuring The Ocean Sr2
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. -

Hardware Features Status Indicator LEDs The Ocean SR2 features two indicator lights that operate as shown: Steady Flashing Unit is on Unit is transmitting Green data NOTE LEDs can be turned off in OceanView or by using a software API command in OmniDriver or OceanDirect. - Page 13 16 Pin IO Connector This port allows the Ocean SR2 to be connected to Ocean Insight light sources Pin 1 and other external equipment. 15 13 11 9 7 5 3 1 16 14 12 10 8 6 4 2...
- Page 14 External Reset Input Pin The Ocean SR2 can reset itself via an external reset pin. Applying a logic low input to the RSTn pin places the SR2 into a hardware reset condition and will remain in reset until the input is brought high again. Note that this is a full hardware reset, all operating parameters are also reset to defaults that can be restored by re-initializing via software commands.

Page 15: Troubleshooting
Windows Operating Systems If you connected your Ocean SR2 device to the computer prior to installing your spectroscopy application (OceanView) on a Windows platform, you may encounter installation issues that you must correct before your Ocean Insight device will operate properly. -
Page 16: Frequently Asked Questions
The system should now be able to locate and install the correct drivers for the USB device. Apple Mac OSX Operating Systems Since there are no device files for the Ocean SR2 Spectrometer in a Mac operating system, you should not encounter any problems if you installed the spectrometer before the operating software. - Page 17 I connected the Ocean SR2 to the computer before installing my spectroscopy operating software to install the drivers. What do I do now? As detailed below, the steps to take to resolve this issue differ, depending on your computer’s operating system.

Page 21: Timing Signals
Timing Signals Single Strobe Output Synchronization of external devices to the spectrometer's integration period can be accomplished with the Single Strobe Output. The Single Strobe Output is an active-high programmable pulse that occurs at a user-defined time during each acquisition cycle. This pulse has a user-defined delay (t ) and a user-defined width (t ). -
Page 22: External Triggering
Triggering Modes The Ocean SR2 supports three triggering modes, which are set with the Trigger Mode command. Detailed information of each triggering mode follows. Also, refer to the External Triggering Options document located on our website at OceanInsight.com. - Page 23 The integration delay, t starts after t and ends before the start of integration time, t . The integration delay is the sum of INTDLY, PROC INTEG the user defined acquisition delay, t (entered in OceanView software) and t ACQDLY BUSY1 The integration period, t , is user defined but has a minimum value of 1 µs.
- Page 24 Time Symbol Description Notes Software Trigger Command Start of Acquisition Cycle System dependent (e.g., computer Trigger Command Processing PROC hardware, software, driver) Acquisition Delay 0 µs 21.47 s User specified, 1 µs resolution ACQDLY 1 µs for t >= t INTEG BUSY2 Busy...
- Page 25 External Edge Trigger The External Edge Trigger mode for the spectrometer looks for a trigger signal on the 16-pin connector. The trigger signal must have a minimum high time of 10 ns. Once the external pulse rising edge is detected, there is a short delay, t before the acquisition ETRGDLY, cycle begins.
- Page 26 Time Symbol Description Notes External Edge Trigger Start of Acquisition Cycle External Edge Trigger Pulse Width 10 ns ETPH External Edge Trigger Delay 30 ns ETRGDLY Acquisition Delay 0 µs 21.47 µs User specified, 1µs resolution ACQDLY 1 µs for t >= t INTEG BUSY2...
- Page 27 The single strobe function for the case of an edge trigger event is similar to that of a software trigger. The start of the single strobe pulse begins with the start of the integration delay. Also, the continuous strobe signal function is the same as that of the software trigger and starts with the start of the integration cycle.
- Page 28 Since the integration is not predefined (user defined), the minimum integration time is no longer 1 µs. The minimum integration effectively becomes the maximum busy time 1, t , which is 218 µs. The user can still define an acquisition delay; however, the BUSY1 minimum integration remains fixed.
- Page 29 Again, the single strobe signal functions the same as the two previous trigger modes. However, the continuous strobe signal is slightly different. For this case, the continuous strobe signal starts at the same time as the single strobe, start of t , and is INTDLY exercised for as long as the trigger level pulse is high or at least until the start of spectrometer busy time, or the start of t...
