USB Programmer
Installation and Operation Instructions
Description
The Ocean Optics USB Programmer enables you to reprogram the EEPROM chip in your USBenabled Ocean Optics spectrometer. Additionally, in certain situations, the USB Programmer allows
you to recover a corrupt EEPROM program from a USB-enabled Ocean Optics spectrometer (if
EEPROM programming is interrupted in mid-program).
USB Programmer Interface
The USB Programmer offers a simple-to-use interface with intuitive controls that allow you to quickly
and easily manage and correct EEPROM-related issues, should they arise.
Note
The USB Programmer is an extremely powerful tool. You should not make any
changes to your USB devices with the USB Programmer without a compelling reason
to do so.
The following sections provide instructions on both programming EEPROM chips and recovering
corrupt EEPROMs with the USB Programmer.

USB Programmer Installation and Operation Instructions
Interface Controls
The USB Programmer interface is an intuitive, easy-to-use console. The paragraphs below detail the
various commands and controls available in the USB Programmer interface.
Menu Commands
The following commands are available from the Menu bar in the USB Programmer interface:
File Menu
The File menu contains the Unlock Features and the Exit options.
File Menu Options
Unlock Features – Displays the Unlock Features dialog box. Enter the appropriate code in
this dialog box to unlock features customized for your equipment (if applicable).
Exit – Closes the USB Programmer and exits the program.
Help Menu
The Help menu contains only the About USB Programmer option, which displays the About USB
Programmer
program.
dialog box. This dialog box provides information on the installed version of the
Command Buttons
The USB Programmer interface also contains the following four command buttons that perform
various functions.
Refresh Tree – Updates the status of all connected USB devices and performs a system scan
for newly attached USB devices. Once updated, these devices are displayed in the left pane of
the USB Programmer interface.
Get All Values – Refreshes the data shown in the right pane of the USB Programmer for the
currently selected device. You can edit specific entries for a selected device by doubleclicking directly on the entry in the right pane of the USB Programmer.
Save All Values – When data for a specific device is displayed in the right pane of the screen,
you can double-click on individual entries and modify the existing data in the EEPROM.
Then, you can save the newly edited values to the EEPROM. The Save All Values button
saves all changes you have made to data in the right pane of the USB Programmer to the
EEPROM of the selected device.

Program – Commits the changes made in the USB Programmer interface to the EEPROM in
the selected USB device. When a USB device is selected, clicking this button brings up the
EEPROM update file dialog box. See the

Caution
Do not interrupt the programming process for any reason! If the programming
process is interrupted, permanent corruption can occur in the EEPROM on the
USB device. Consult the Recovering a Corrupted EEPROM section of this
document for a procedure that may rectify this condition.
Reprogramming a USB Device
► Procedure
Follow the steps below to re-program the EEPROM in a USB device:
1. Download and install the USB EEPROM Programmer utility from the Ocean Optics website:
http://www.oceanoptics.com/technical/softwaredownloads.asp
This utility installs the latest version of the microcode for all Ocean Optics devices.
2. Connect the USB device to the PC.
3. Run the USB programmer by selecting
| USB Programmer
In the left pane of the interface, the USB Programmer displays all Ocean Optics USB devices
that are currently connected.
4. Click on a device to select it.
Once you select a device, detailed information for that device is displayed in the right pane of
the interface. The current firmware version of the selected device is displayed in the first entry
on the right pane.
5. Press the
Ocean Optics USB device. Programming begins immediately, and the estimated time for
completion of the reprogramming process displays in the bottom status bar.

Caution
Do not interrupt the programming process for any reason! If the programming
process is interrupted, permanent corruption can occur in the EEPROM on the
USB device. Consult the Recovering a Corrupted EEPROM section of this
document for a procedure that may rectify this condition.

USB Programmer Installation and Operation Instructions
EEPROM update files are installed in the same location as the USB Programmer utility. The
default location is C:\Program Files\Ocean Optics\USB Programmer.
6. Unplug the USB device from the PC when programming is complete, and then plug the device
back into the PC to allow the new EEPROM program to take effect.
Recovering a Corrupted EEPROM
If the programming process was interrupted, the EEPROM may be irretrievably corrupted. However,
the device still may be functioning properly. Typically, devices with corrupted EEPROMs that will
function properly are indicated in the Windows Device Manager with a yellow exclamation point icon
and the title “Unknown Device.” This normally means that the PC is missing a configuration file for
that device.
You can attempt to restore the EEPROM to a useable state using the USB Programmer.
► Procedure
Follow the instructions below to attempt to restore a corrupted EEPROM:
1. Download and install the USB EEPROM Programmer utility from our website:
http://www.oceanoptics.com/technical/softwaredownloads.asp
This utility installs the latest version of the microcode for all Ocean Optics devices.
2. Unplug the USB device from the computer.
3. Use a paper clip or small piece of wire to short the SDA pin on the USB device to the ground.
Consult the data sheets for your specific device to determine the location of the SDA pin and
the ground:
http://www.oceanoptics.com/technical/engineeringdocs.asp
4. Connect the device (with the pin shorted) to the PC to power it up.
5. Remove the shorting wire.
6. Run the USB programmer by selecting Start | Programs | Ocean Optics | USB Programmer |
USB Programmer.
7. Locate the USB device under the Unprogrammed OOI USB Devices section in the left pane.
If the unit does not appear in this section, repeat Steps 3-6, ensuring that the appropriate pin is
shorted to the ground.
8. Click on the USB device and then click the Program button. The Select EEPROM Program
dialog box appears.
9. Select the appropriate EEPROM file for the USB device, and then click the Open button.
Programming begins immediately, and the estimated time for completion of the
reprogramming process displays in the bottom status bar.
