Firmware Upgrade
After initial driver installation or an oscilloscope firmware upgrade, it may be
necessary to upgrade the dongle firmware on the USB2-GPIB. A pop-up window
will appear to indicate incompatibility and instruct you to remove the device.
Follow these steps to upgrade the dongle firmware:
1. Download USB2-GPIB dongle firmware upgrade from
teledynelecroy.com. Extract this archive to a local folder of the PC
(e.g., C:\Temp).
2. Before reconnecting the USB2-GPIB device to the PC, open the
Windows Device Manager utility on the PC.
3. While pressing the dongle button underneath the case, plug the USB2-
GPIB USB connector into the PC’s USB port. The dongle should show
up as AT32UC3A in the Windows Device Manager list of devices.
4. Install the Atmel USB DFU driver:
•
Right click on AT32UC3A in the Device Manager and choose
Update Driver Software.
•
Browse to the Atmel_DFU_USB_Driver folder of the extracted
download archive.
The dongle should now show up as AT32UC3A3 under the Atmel USB
Devices folder of the Windows Device Manager list of devices.
5. Double-click the DFU_UpgradeDongleFW.bat file in the driver folder,
which will upgrade the dongle with the latest firmware. The dongle
firmware upgrade is successful if the red LED is on.
