5INTRODUCTION
The SLR350Ni from Comar Systems is a compact, dual channel synthesized VHF AIS Receiver
equipped with Ethernet, WiFi and USB Interfaces for land-based, shore side monitoring. It is
designed to receive and decode all AIS transmissions from vessels fitted with Class ‘A’ or ‘B’ AIS
transceivers, Aids to Navigation, and SART.
The SLR350Ni is based on the popular Raspberry Pi™31mini-computer and is optimised for coastal
monitoring of AIS equipped marine traffic. The SLR350Ni is primarily intended for developers to
implement within their own AIS monitoring networks. With compatible plotting software - for example,
OpenCPN2- AIS data can be received from vessels within range of the antenna and displayed on a
monitor in a visual representation.
●Before operating the unit you should familiarise yourself with this user manual
●The SLR350Ni is intended to be developed continually, therefore this manual should be
considered as a guide
