R550Ni 4 GENERAL NOTICES SAFETY: Make sure the power supply is switched off before you make any electrical connections to the unit. INSTALLATION: This equipment must be installed in accordance with the instructions provided in this manual. Failure to do so could result in poor performance, personal injury and/or damage to your vessel and/or connected equipment.
Class ‘A’ or ‘B’ AIS transceivers, Aids to Navigation, and SART. The R550Ni is based on the Raspberry Pi Compute Module 4 and is optimised for coastal monitoring of AIS equipped marine traffic. The R550Ni is primarily intended for developers to implement within their own AIS monitoring networks.
Connect the Antenna & Ethernet cables first, then proceed to connect the supplied USB-C cable to the USB-C socket on the side of the R550Ni, see section 6 MAJOR DIMENSIONS. Provided that the unit is configured correctly, the receiver will immediately begin the boot process. Refer to section 8 CONFIGURATION.
R550Ni 8 CONFIGURATION There are several methods to configure the R550Ni unit, ranging from the standard configuration using a keyboard and mouse directly connected to the unit (After initial setup a bluetooth mouse and keyboard may be used), or by using VNC or SSH which are done via a network.
One example for a VNC client is RealVNC: www.realvnc.com. Once your client is installed, ensure the R550Ni is powered on and connected to your network via ethernet or Wi-Fi. Follow the instructions of the VNC client to connect to the VNC server on your R550Ni unit.
The R500Ni and the R550Ni are both AIS receivers based on a Raspberry Pi micro-computer. The fundamental difference between the two models is that the R550Ni is based on a Raspberry Pi Compute Module 4 (CM4) module, which used built-in eMMC memory (rather than SD card) for storage of the Operating System and Software, where as the R500Ni uses a Raspberry Pi 3B+ with removable micro-SD card.
The ‘rpiboot’ software opens in a command-prompt, and waits for the CM4 to be connected. On the R550Ni, the ‘Boot’ switch should be set to on: Connect the USB - C cable to the R500Ni. The RpiBoot program should register the unit and install a boot loader.
For R550Ni with Compute Module 4 (CM4) or R500Ni with Raspberry Pi 4 chose Choose the OS required For R500Ni with Raspberry Pi 3B+, we suggest, but the choice is yours For R550Ni with Compute Module 4 (CM4) or R500Ni with Raspberry Pi 4 we suggest,...
• Set the Boot switch to off. • Connect Keyboard, Mouse and HDMI display to the R500Ni or R550Ni. • (connect Ethernet cable, if you need to, or you can connect to the internet via WiFi. If you didn’t configure the Wifi settings when loading the image, you can configure it later.

R550Ni Then ask for settings for user name & password (if not pre-configured). Note: The username of ‘pi’ and password of ‘Raspberry’ are insecure defaults. We use them in-house during development and testing to save having to remember different users / passwords for different units, but would recommend you use something of your own choice.
R550Ni 9.4 Loading an existing OS image To load an existing OS image on to the R500Ni or R550Ni, please follow the instructions for “Method of loading OS image onto memory for Raspberry Pi” above, to prepare the device for loading the OS image.

R550Ni 9.5 Installing OpenCPN If you wish to install OpenCPN on your R550Ni, the method will depend on the OS you have installed. For OpenCPN, (open-source charting program which will display received AIS data on nautical chart) please refer to the openCPN website https://opencpn.org/ for instructions on loading on to your chosen operating system.
Note, it is very important to leave clear access to the ventilation Mounting: holes on the bottom and side of the enclosure. The R550Ni should be mounted horizontally, or such that the side ventilation holes are at the top. USB-C (Power);...

R550Ni 14 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.
