1. Enter the slave bootloader mode, as described
previously on page 12. Do not remove the USB
cable.
The DFU driver can only be installed when in the
slave bootloader mode.
Install the DFU driver and follow the instructions
of the installation wizard. To install the driver,
launch Setup32.exe or Setup64.exe, depending on
whether you are using a 32 or 64 bit version of
Windows.
The driver is located in the User Manual CD, under
the “Driver\DFU Driver Setup” directory.
If a Windows Security message appears, choose
“Install this driver software anyway”.
Note: The GOM-804/805 must be in slave
bootloader mode to install the DFU driver.
2. Check to see that the DFU driver was successfully
installed in the Windows Device Manager.
3. Press: Start > Control Panel > Hardware and
Sound > Device Manager.
4. There will be a new item in the device tree, “GOM
Device Firmware Upgrade”, when successful.
