Part Number:CS-R400NX

 Lantronix Xport Edge Module Version 


The R400NX provides a method of monitoring the position, speed and heading of AIS vessels within VHF range. It can decode of 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 R400NX 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.

Lantronix:  will allow multiple incoming connections, which means the AIS receiver acts as the TCP server that multiple TCP clients connect to. The R400NX and R400NXG has the Lantronix Xport Edge module included. Please see the “Multiple Connection” (TCP) setting below (marked in red).

Please note that this is only possible for incoming connections. If you want to connect your AIS receiver to multiple TCP servers as a client, this cannot be achieved with the R400NX or R400NXG.

You could instead use our R500Ni or R500NGi intelligent AIS receiver. This device includes a Raspberry Pi single board computer and with the right software can handle multiple TCP connections. Please note that the R500Ni does not come with any OS or software and all software will have to be developed by the user.

Note: This product was previously known as the SLR350N
