The R400NXG is an AIS receiver unit with built in GPS receiver, Ethernet interface and USB port is designed specifically for coastal monitoring of AIS equipped vessels.
Connected to an Ethernet Network directly or via a Router to a PC running compatible software, AIS data transmitted from ships within range can be displayed on the screen giving a visual interpretation of the traffic within VHF range. The unit can also be mounted at a remote location and AIS data sent over the Internet to a fixed IP address for use on a dedicated server.
The R400NXG has been specifically designed for use by the professional market and uses Comar’s well proven and internationally specified high sensitivity dual channel parallel receiver.
