Troubleshooting
Verify that all NHD devices contain the latest version of firmware. This will ensure that all devices are up to date and working at their highest performance
level.
NetworkHD Software fails to locate TX/RX/CTL Devices
• Verify that all NHD and Network devices are powered On.
• Adjust Windows Firewall Settings – Create an exception for NetworkHD
Console.
• Verify that the PC, CTL AV Port, and NHD encoders and decoders are on the
same LAN/VLAN/Subnet.
• Verify that all network switches share the same VLAN configuration.
• Reboot all system components including the NHD-000-CTL and the PC.
• Ensure that only one CTL port is connected per LAN/VLAN. If only one LAN/
VLAN exists only use the AV port.
• Ensure the network switch is fully configured per the appropriate switch
configuration guide.
Failure to Connect to CTL Controller
• Follow the previous steps for failing to connect to devices. If these are
unsuccessful, press and Hold the reset button on the front of the CTL for 5
seconds.
• After a reboot the CTL will be returned to the default IP address of
192.168.11.243 for the control port and 169.254.1.1 for the AV port.
No Image Appearing on Displays
• Verify that all NHD, Network, Source, and Display devices are powered On.
• Verify that the configuration in NetworkHD Console is correct based on
system layout and components used.
• Test sources and displays by connecting them directly together.
• Swap out the HDMI cable.
