NOTE

Be sure to install the spectroscopy software BEFORE connecting the spectrometer to your PC. The software installs the drivers required for spectrometer

installation. If you do not install the software rst, the system will not properly recognize the spectrometer. If you have already installed the Ocean ST 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 ST installation.

Installation and Setup

Software Installation

Use OceanView version 2.0.10 and above for Ocean ST. You can use OceanView on the following operating systems:

Consult the OceanView manual for computer hardware requirements.

Windows Mac

8 8.1 10 OS X Version 10.5 or later on

Intel processor

*Software may run with previous operating systems but Ocean Insight does not actively support these installations.

NOTE

Be sure that you download the correct software package for your computer version (32 or 64-bit). See Frequently Asked Questions in Troubleshooting

for more information on determining your computer version.

Conguring the Ocean ST

The Ocean ST 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 ST 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 ST to a computer via the USB port:

1. Install the spectrometer operating software on the

destination computer.

2. Locate the USB cable (CBL-USB-AMCM) provided with the

Ocean ST.

3. Insert the micro connector end of the cable into the side

of the Ocean ST and the larger end of the cable into the USB

port of the computer.

4. Connect any spectroscopy accessories. To nd operating

instructions for Ocean ST-compatible products (such as light

sources, sampling chambers, and probes), consult the Ocean

Insight website at OceanInsight.com.

5. Attach the ber to the ber optic connector on the

spectrometer.

If you installed the spectrometer operating software prior to

connecting the Ocean ST, the software automatically installs

the correct drivers. If the drivers do not successfully install

(or if you connected the Ocean ST to the computer before

installing the software), consult Troubleshooting.

Frequently Asked Questions

I connected the USB cable and started OceanView but I don’t see my

spectrometer attached.

Use the “Action -> Scan for hardware changes” selection in the Device Manager to rescan for

attached devices.

I am having trouble installing the drivers, what should I do?

Hardware device driver installation is usually seamless on Microsoft Windows operating systems

and should happen in the background when you connect your spectrometer to a computer with the

software installed. However, some Windows systems require a bit more care when connecting your

spectrometer for the rst time.

If your spectrometer is not recognized by OceanView on your computer, you need to manually

install the spectrometer drivers. See your OceanView manual for this procedure.

I’m installing OceanView but I need a product key; where can I nd this?

The product key was sent to the contact e-mail on the sales order when you purchased your OceanView license. Contact [email protected] for more

information. You’ll need your sales order number, quotation number, the serial number of the spectrometer that was purchased with the software, and, if

known, the e-mail address under which your product key was created to recover your key.

I connected the Ocean ST to the computer before installing my spectroscopy operating software to install the

drivers. What do I do now?

As described at the beginning of the Troubleshooting section, the steps to take to resolve this issue differ, depending on your computer’s operating system.

How do I check the conguration of my spectrometer?

Check the label on the bottom of your spectrometer. You can also check your conguration using OceanView by opening the Schematic window and double-

clicking the spectrometer icon.

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-dened time during each acquisition cycle. This pulse has a user-dened delay (tSSDLY) and a user-dened

width (tSSH). Both values are programmable in 1 µs increments for the range of 0 to 65,535 µs.

The timing of the Single Strobe signal output is referenced from a Trigger Event. The Single Strobe Delay denes the time from the Trigger Event until the rising

edge of the Single Strobe output. Note that a programmed Acquisition Delay can cause the Single Strobe to pulse before the start of integration. After the Sin-

gle Strobe Delay has elapsed and the Single Strobe Output has gone high, it will remain active for a duration equal to the Single Strobe Width. The Single Strobe

Output will return to a low or inactive state at the end of the Single Strobe Width.

If the Single Strobe Output is programmed for a longer period than the integration time, it will reset to its inactive state at the end of the integration period.

See timing diagrams later in this section for more information of the Single Strobe Timing.

Synchronous Continuous Strobe

The Continuous Strobe output signal is a programmable pulse that occurs at a user-dened time during each acquisition cycle. The Continuous Strobe is a

series of pulses dened by a user-dened period with a 50% duty cycle. The Continuous Strobe Period (tCSPER) has a resolution of 10 µs. The polarity is also

selectable so that the Continuous Strobe signal period starts with either a 0 or 1.

The Continuous Strobe signal is only valid during the integration period (tINTEG). The Continuous Strobe period has a resolution of 10 µs for a range of 0 to

655,350 µs. However, the Continuous Strobe signal is only exercised if it can complete a full period within the integration period. If there are multiple Continu-

ous Strobe periods within an integration period, only full periods are realized. This means the time between the last Continuous Strobe period and the end of

integration time is between 0 and tCSPER.

For the Continuous Strobe signal to be fully realized for at least one period, the integration time must be greater than or equal to the Continuous Strobe Period.

See timing diagrams for more information about Continuous Strobe Timing.

Triggering Modes

The Ocean ST supports two triggering modes, which are set with the Trigger Mode command. Detailed information about each triggering mode follows. Also,

refer to the External Triggering Options document located on our website at OceanInsight.com.

The two trigger modes are:

Software Triggering: A trigger is initiated internal to the Spectrometer with a command from Ocean Insight approved software. The integration period is set by

software conguration.

External Edge Triggering: A trigger is initiated by the rising edge of the external trigger signal on the auxiliary connector. The integration period is set by soft-

ware conguration.

Software Trigger

The default triggering mode is for a software trigger. A Software Trigger may be initiated by either OceanView, OmniDriver, or OceanDirect software. Once a

command is sent to the Spectrometer, an internal trigger is generated, which begins an acquisition cycle.

If a start time of T0 is dened as the moment a software command requests an acquisition, then there is a latency time of tPROC, which is the Software Com-

mand Processing time from T0to when the integration cycle starts. This latency varies from computer system to computer system.

The integration delay, tINTDLY, starts after tPROC and ends before the start of integration time, tINTEG. The integration delay is the sum of the user dened acquisition

delay, tACQDLY and tBUSY1.

The integration period, tINTEG, is user dened but has a minimum value of 1560 µs.

Following the integration period, the detector is busy to nish the acquisition cycle and that time is tBUSY2. After this time, the detector is ready for another trigger.

The equation for the integration delay can be written as

tINTDLY = tACQDLY + tBUSY1

where tBUSY1 = 1560 µs

The single strobe is active at the end of tPROC and with the start of the acquisition delay, tACQDLY. The single strobe itself can have a delay dened as tSSDLY. The

single strobe is a single pulse that goes high at the end of tSSDLY and stays high for a time of tSSH. The values for the single strobe delay and pulse high time are

set by the user in OceanView or OceanDirect software.

The continuous strobe signal is a series of pulses with a user specied period that starts with the beginning of the integration time, tINTEG. The pulses have a

50% duty cycle and only full periods are exercised during an integration period. If a subsequent continuous strobe period cannot be completed before the end
