Flexible expandability allows the ECDIS to be networked with ARPA Radar, positioning equipment, autopilot and others to consolidate the navigation system. The 100 Base-TX Ethernet is utilized to link the FEA-2107/2807 with up to four sets of FURUNO ARPA Radar FAR-21x7/28x7 series. This link gives high-speed and stable navigation data sharing within the network and gives option in building up a variety of navigation system from a single station through complete Integrated Navigation System (INS).
