The LCS85 connects directly to IP Ethernet networks running at 10, 100, or 1,000 Mbps. Multiple LCS85s communicate with each other over the network, and one LCS85 can act as the Site Director. Authorized users log in to the Site Director via a supported browser to access the entire Metasys system for the site. Data transmission on the network uses standard IT protocols, services, and formats. Networks in different buildings may be interconnected using standard WAN technologies and network service providers. The speed of transmission depends on the technology used.
