Chapter 7. Firmware Update

Please follow following steps for updating the DVK-400 firmware.
1. Please download the latest DVK-400 firmware from the Datavideo official website
www.datavideo.com
2. Please prepare a USB thumb drive and then please unzip the downloaded firmware file to the
root directory of the USB thumb drive. Please make sure that the USB thumb drive must be
formatted to FAT16 or FAT32 format in advance.
3. Please unzip the downloaded firmware file to the root directory of the USB thumb drive and
then you can see that there are two files including DVK400FW.bin & DVK400FP.bin.
4. Please insert the USB thumb drive into the FW UPGRADE interface which is located on the rear
panel of the DVK-400.
5. Please connect any SDI OUT or HDMI OUT to an external connected monitor and then please
turn on the power of the DVK-400. After that, the firmware upgrading of the DVK-400 will be
started automatically. It will cost for about 1 minutes and there is no picture that will be shown on
the screen. If there is any LED indictor on the USB thumb drive, the LED will be blinking.
6. After the firmware update process is done, all of the HDMI or SDI output interfaces will output
the 1080p 59.94 color bar which is shown as following diagram. When the color bar is shown, it
means that the firmware update procedure is done and the USB thumb drive can be removed.
Note: If the firmware update procedure is failed, there is no output screen for about 1 minutes.
Please connect your notebook PC to the DVK-400 by the PC DVK-400 App (by RS-232 or DVIP
interface). After the connection is established, the color bar will disappear and the resolution will
go back to the original resolution. Please check whether the Firmware, FPGA and Bootloader
versions are updated correctly or not through the SETUP option.
