Changes between the R400NG and R400NXG:

The difference between the R400NG and R400NXG is the network module installed within the product. The R400N uses a Digi module, whereas the R400NX uses a Lantronix XPort module, which follows a slightly different setup process. View the R400NG.


The R400NXG is an AIS receiver unit with a built-in GPS receiver, Ethernet interface and USB port 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 is 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.
