R500Ni 5 INTRODUCTION The R500Ni 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.
& Ethernet cables first. Lastly, connect the power cable by plugging the micro-USB power jack into the micro-USB socket on the side of the R500Ni, see section 6 MAJOR DIMENSIONS. Provided that the unit is configured correctly, the receiver will immediately begin the boot process.
Raspberry Pi 3™ micro computer. Full information and additional details can be found on the Raspberry Foundation website: https://www.raspberrypi.org/ The R500Ni can run a number of operating systems and these are listed and explained on the official Raspberry Foundation website. Comar Systems recommend using Raspbian, the official operating system (OS) for the Raspberry Pi, which is a Linux based OS.
To use the AIS receiver you have to enable the serial port and set the communication parameters. This applies to all uses of the R500Ni; see below. 8.4 Enabling the Serial Port In the later Jessie releases the GPIO serial port is disabled by default.

The next step is to disable the remote console which by default uses the internal serial port ttyS0 which is also the same serial port the AIS receiver uses in the R500Ni. To do this, type: $ sudo systemctl stop serial-getty@ttyS0.service $ sudo systemctl disable serial-getty@ttyS0.service...
$ stty –F /dev/ttyS0 38400 Make sure that the AIS antenna is connected. You should now be receiving AIS data on the internal serial port. Check that the red LEDs on the side of the R500Ni are flashing; these indicate data being received.
R500Ni 8.5 Installing OpenCPN OpenCPN works on Raspberry Pi 3™ model which is embedded in the Comar R500Ni. There are three options for installing OpenCPN: 8.5.1 Option 1: A complete installation including the Raspbian OS If you feel lazy you can use OpenPlotter, a complete marine Operating System for Raspberry Pi with the Raspbian OS, OpenCPN and plugins installed and extra tools ready to use.
R500Ni 8.5.3 Configure the OpenCPN Start OpenCPN from the GUI. On the menu -> option -> connections Add a connection ->Serial Set Baud Rate 38400 Select Port /dev/ttyS0 Click the Apply button and the setup is complete.
If a new version of OpenCPN is released, just type: $ sudo apt-get update $ sudo apt-get install opencpn You should now be up and running with the R500Ni displaying NMEA data either from the serial port or on a visual chart plot. 9 FAULT FINDING 9.1 Power LED not illuminating...

R500Ni 13 APPENDIX 1 – BACKGROUND TO AIS The marine Automatic Identification System (AIS) is a location and vessel information reporting system. It allows vessels equipped with AIS to automatically and dynamically share and regularly update their position, speed, course and other information such as vessel identity with similarly equipped vessels or shore installations.
