The Network Config Tool is used to set the IP settings for XPA BRB and nADR devices.
It is available as part of SensorView 13. A version is also hosted on Box, but it may not be up to date.
Ensure that your computer has a valid IP address (check your computer's network settings - you may have to manually specify an IP address if the network does not have a DHCP server).
Run as an administrator.
Check your computer's firewall. When connecting to the network, say "yes" to "Allow Windows to search for TVs and PCs".
Very old XPA BRG devices (below 2.1.12) do not support the tool, and require the use of a serial cable.
