6 210-00000-000-02-201502
Serial Port Mode
To use the serial port capacity of the HR4000 Spectrometer, the PC must be running a 32-bit version of
the Windows operating system.
►
Procedure
Follow the steps below to connect the HR4000 to the PC via serial port:
1. Connect the serial cable adapter block to the appropriate pins of the HR4000’s 30-Pin Accessory
Connector.
2. Connect one end of the 9-pin serial cable to the adapter block on the HR4000, and then connect
the other end to a serial port on the PC.
3. Note the number of the serial port (COM Port) to which you connected the HR4000 (some PCs
may not have numbered ports; handheld PCs typically have only one serial port).
4. Plug the 5 VDC external power supply into an outlet and connect it to the HR4000.
Connect Spectroscopic Accessories
To find operating instructions for HR2000+-compatible products (such as light sources, sampling
chambers, and probes), consult the Ocean Optics website at http://oceanoptics.com/support/technical-
documents/.
HR4000 Configuration
The HR4000 can be used with OceanView operating software when connected to the USB port.
If you have followed the previous steps and started OceanView, 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.
External Triggering Options
You can trigger the HR4000 using a variety of External Triggering options through the 30-pin
Accessory Connector on the spectrometer. For HR4000 firmware versions below 3.0, see the
External Triggering Options document located at http://oceanoptics.com///wp-

External Triggering Options document located at http://oceanoptics.com///wp-content/uploads/External-
Triggering-Options_Firmware3.0andAbove.pdf. The triggering document contains instructions for
configuring External Triggering options for the HR4000.
