4-Port Switch Provides VLAN Capability

August 20, 2012
4-Port Switch

Communication Networks (ComNet) introduced a four-port self-managed Ethernet switch. The switch has four TX Ethernet ports that allow the Ethernet data from three of the TX ports to be combined and inserted onto the network through the fourth TX port. The self-management feature requires no user intervention and is pre-programmed to avoid flooding the network. The CNFE4SMS offers management without the cost or user knowledge required for a managed switch. This port-configured Ethernet switch allows the user to create a virtual local area network (VLAN) that manages the Ethernet data being transported. The fourth port forwards the data from the three electrical ports to the next switch, a PC or another Ethernet connection. Distances up to 100 meters are supported. The CNFE4SMS is a cost-effective way to add IP video to a network.
