External Triggering Instructions

Using the External Synchronization Trigger Mode
► Procedure
1. Supply a line from Pin 5 of the J2 Accessory Connector to the triggering device. (See figure in
Pinout Diagrams for Ocean Optics Spectrometers on page 2 for pin location.)
2. Connect Pin 10 of the J2 Accessory Connector (ground) to the ground of the triggering device.
3. Click the Data Acquisition icon or select Spectrum | Configure Data Acquisition from the
OOIBase32 menu bar and set the other acquisition parameters.
4. Select the External Trigger page on the Configure Data Acquisition screen and select
Synchronization.
5. Enable the Automatically save file on trigger box if you wish to save the data to a file after each
trigger.
If you enable this function, OOIBase32 displays a file save dialog box after each trigger. To avoid
manually naming a file for each trigger, you can enable the Autoincrement Filenames function
from the File | Autoincrement Filenames | Enabled option in the menu bar.
Note
Once you select an external trigger mode, your computer will appear unresponsive. This
is normal, as the computer is waiting for a trigger.
External Hardware Trigger Mode – USB2000, USB2000+,
USB4000, Jaz, HR2000, HR2000+ and HR4000
Spectrometers
In this edge-triggered mode, the spectrometer is idle until you apply a trigger to the spectrometer. With
each trigger, the following events occur:
1. The spectrometer is cleared and then begins integrating
2. For USB2000 and HR2000: The spectrometer integrates for 50 milliseconds (you can contact
Ocean Optics if you require a different integration time)
For USB2000+, USB4000, Jaz, HR2000+ and HR4000: The integration time is selectable in
software
3. The data is transferred to the software; the spectrometer then sits idle waiting for the next trigger
