Connecting a Digital Yacht AIS to a Raymarine Classic C Series
The original Raymarine C Series multi-function display (MFD), now referred to as the “Classic” C Series, is a
very popular chart plotter that supports connection to an AIS unit via NMEA 0183. The “Classic” C Series
only has one NMEA 0183 port and this is often connected to other devices, which can cause complications
when a customer wishes to add AIS to the system.
Digital Yacht have designed and tested a number of solutions to this problem and this technical article
details how to connect a Digital Yacht AIS to this popular multi-function display. Only Digital Yacht products
that have an NMEA 0183 input (multiplexer) can be used in some of the solutions we outline in this
document so please check that your Digital Yacht AIS has this feature before purchasing.
SOLUTIONS:
On the rear of the C Series are six connections. The five pin NMEA In/Out cable is the one that we need to
connect the AIS to. The diagram below shows the wire colours and connections.
Check this cable to see if any other equipment is already connected to it. The two most common NMEA
connections to the C Series are;
1) The C Series Output (GPS position) is connected to a DSC VHF
2) The C Series Input is connected to the High Speed Heading output from a Raymarine Autopilot
Course Computer or other compass sensor.
If your installation is configured in either of these two ways, jump to the relevant solution on the following
pages.
*** We strongly recommend that all C Series Classic units are updated to the latest V5.04 software (Oct
2010) as this fixes a number of important AIS related bugs.***
Solution 1 – No existing connections to the NMEA In/Out
If you check the C Series NMEA cable and find no other NMEA connections are currently made, then you
can simply connect the Digital Yacht AIS NMEA 0183 Output to the C Series NMEA Input as shown below;
Solution 2 – The C Series NMEA Out is connected to a DSC VHF
If you check the C Series NMEA cable and find that it is connected to a DSC VHF, then you will need to
configure the Raystar 125 GPS to work on NMEA 0183 rather than SeaTalk. The diagram below shows how
the system is currently connected (left) and how the system needs to be reconnected (right).
Consult the Raymarine manual for the Raystar 125 on how to configure it to work on NMEA0183 rather
than SeaTalk, but the connections you will need to make are shown below. The Raystar 125 GPS data will
now be multiplexed with the AIS data and output to the C Series at the NMEA (HS) 38,400 baud rate.
Solution 3 – The C Series NMEA Input is connected to a High Speed Compass
If you check the C Series NMEA cable and find it is connected to the NMEA High Speed Compass output of
a Raymarine autopilot course computer or other heading sensor, then you will need to disconnect this
NMEA High Speed Compass output from the C Series input and connect it to input of the Digital Yacht AIS
unit. This compass data will then be multiplexed with the AIS data and output to the C Series at the NMEA
(HS) 38,400 baud rate.
IMPORTANT NOTE:- The above diagrams are applicable to all Digital Yacht AIS units except the ANT200.
For the ANT200 the NMEA output wire is Grey (not Orange).
