NVISION Enterprise routers use TCP/IP to communicate with external devices. The port must be 9193. You also need to specify the NVISION controller's host name or IP address when configuring it in Router Manager. After you have created the router and levels with the appropriate dimension and saved configuration, physical levels will be updated automatically for you.

Also, in order to fetch labels, take crosspoints or connect free source, NVISION Enterprise routers will use virtual device id for levels, destinations or sources.
