b) 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 controller computer
(e.g., C:\Temp).
2 Before reconnecting the USB2-GPIB device, open the Windows Device
Manager utility on your computer. Go to the Windows Start Menu and
choose Control Panel > System > Device Manager.
3. While pressing the dongle button underneath the case, plug the
USB2-GPIB dongle into the computer 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.”
• If using Windows 7, choose “Browse my computer for driver software”,
if using Windows XP, choose “Install from a list or specific location
(Advanced).”
• 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.
