NVS-25 Network
Connection Guide


When you connect your NVS-25 to your network and run our IP scanner software, if you are unable to find the unit, it is possible that your network is not assigning it an IP address for a number of reasons.
 

  • Does your network have a DHCP server?
  • Does your network admin have rules setup to block new devices?
  • Your antivirus or firewall is preventing communication
  • Your network is blocking older versions of Apache Server
A few things you can try are:
  • Restore factory defaults on the NVS
  • Restart your computer
  • Temporarily disable any antivirus or firewall software
  • Run "services.msc", right-click on "DHCP Client", and select "Restart"
  • From Command Prompt, type "ipconfig/flushdns", followed by "ipconfig/release" and "ipconfig/renew"


If none of these work, the good news is that the NVS-25 has a fixed IP address of 192.168.1.20 that you can connect to directly at any time!

This will allow you to set a static IP for your NVS in the range of the network, and allow you to skip assigning an IP via DHCP.
 

  • Connect your PC directly to the NVS with a standard Ethernet cable.
    You do not need a crossover cable for this

The easiest way to change your network settings in Windows 7 or 10 is to:
 
  • Click the Start button
  • Start typing "View Network Connections" and select it when it appears
  • Double-click your network adapter for your wired Ethernet connection or LAN
  • Click Properties
  • Double-click "Internet Protocol Version 4" from the list
  • Click the "Use the following IP address" button

     
  • Set your Windows IPv4 settings to:
    IP Address: 192.168.1.2
    Subnet Mask: 255.255.255.0 (will fill in automatically)
    Default Gateway: 192.168.1.1
     
  • Remember to write down your settings before changing them, as you will need to revert to those settings once this process is complete




     
  • The NVS is now accessible through 192.168.1.20
  • Login using your web browser
  • The default username is admin
  • The default password is 000000
     
  • Click on the Settings tab, followed by Network Settings. Change the IP to a static setting with the same gateway as your network and an IP address that is not already taken.
     
  • For example, if your local network's gateway is 10.10.1.1, then you would enter that, and then give the NVS-25 an IP address of 10.10.1.X, where is is a number between 2 and 255 that is not already taken.
     
 
 
  • Dynamic IP Addressing (DHCP): Disable
  • Static IP Address: X.X.X.Y, where is X is same IP address as your Router or Switch's LAN, and Y is a number not already taken
  • Subnet Mask: 255.255.255.0
  • Default Gateway: Z.Z.Z.Z, where Z is the same gateway address as your Router or Switch's LAN
  • Primary DNS: Same as the Default Gateway. If there are issues, you can also resolve to 8.8.8.8 (Google's public DNS)
     
  • Click Save to make these network settings the new default.
    Clicking Apply will only temporarily change the settings until you power off and on again
     
  • Connect your PC and NVS back to the network.
     
  • Revert your PC's network settings to their previous configuration.
     
  • Reboot the NVS.
     
  • Make sure the drop-down box in the IP Finder is in the same IP range as your network.
     
  • You should be able to scan for it now.
