The Concept LAN Over Ethernet provides a convenient interface for the Concept RS-485 LAN to be distributed over standard TCP/IP Ethernet networks. Ethernet connectivity allows the Concept LAN to traverse TCP/IP architecture including 802.3i (10Base-T) and 802.3U (100Base-T) switching and routing equipment. Wireless communications can also be achieved via wireless router and Ethernet / 802.11 point to point RF solutions. Every Concept LAN Over Ethernet module can be assigned as a master or slave via initial set-up options; the master unit is configured with a static IP address while the slave units support static or dynamic addressing. Multiple master and slave modules can exist within the same network and multiple Concept RS-485 LAN modules can be connected to each slave.
