NVD-20 and NVD-25 Web Update Troubleshooting

Last Updated: Sep 26, 2017 11:08AM PDT
Q: My NVD-20/25 is not prompting me to update
my unit, even though a new version is available.
What can I do to fix it?



Please note that the NVD-30/35 have update
notifications built into the web interface.

When an update is available, you will see a notification
along the top of the browser page.


 
A: Here are a few things you can do:


 
  • The NVD must be left powered on and connected to the internet for a few minutes to check for updates in the background

     
  • When booting, the device will use the monitor's preferred resolution and not the resolution that is set on the NVD Web UI
  • The NVD must be connected to a monitor for you to see the message. Most switchers won't supply the correct preferred resolution to HDMI sources

     
  • Updates will not download when a static IP was set due to DNS not working
  • The NVD must be on DHCP to update

     
  • If you are on a network with an IT administrator and firewall, you likely need for them to open a port to allow the NVD-20 to connect to the internet. Please contact them for support with this

     
  • Open TCP ports 80 and 22 for the update server
  • If using a proxy server, also open port 873
  • The unit must also have a valid IP, gateway and DNS server

     
  • You can also try to resolve the servers address from using the same connection
  • Open Windows' Command Prompt and enter the following command:

     
nslookup updates.datavideo.co.uk
Currently this resolves to 34.253.115.156
