The R400N provides a method of monitoring the position, speed and heading of AIS vessels within VHF range. It can decode Class A, Class B, Aids to Navigation, SARTS and all other AIS message types. When connected to a PC using the industry standard RJ45 Ethernet connector, the R400N enables AIS data to be viewed directly, or shared on a local network. The unit can also be mounted at a remote location and AIS data sent via the Internet to a fixed IP address for use on a dedicated server.

The R400N 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.

Note: This product was previously known as the SLR350N
