Looking for assistance connecting to NMEA 2000
I currently have a Raymarine
SeaTalkng (NMEA 2000) network setup on my boat
with the following instruments connected to the Backbone.
(2) Lowrance HD chart plotter connected using a devicenet cable (i.e NMEA 2000
connector on one end and white seatalkng connector on the other)
The chart plotter provides GPS
, water depth
temperature to the backbone.
(3) Raymarine AIS650.
The network is connected to a mini computer via ACTSENSE NGW-1-STNG.
As it stands opencpn
can control the autopilot
. Its also using the GPS
data from the network. However I cannot get opencpn
to display any AIS
data or water depth
data. I know the AIS
data is available because its displayed correctly on the chart plotter and the water depth is displayed on the autopilot display. I have the PC com port set up with no filtering on the input sentences at 4800 baud. (this is where I'm lost
, the Actisense as I understand it converts NMEA
2000 data to 0183 format (and vice versa) in this case at 4800 baud so it can be used by the PC. But isn't the AIS suppose to be at 38500 baud??..at least with the old 0183 system. I didn't think that applied to NMEA
AIS is well developed in opencpn. So how is the connection to NMEA 2000 accomplished using a single
connection from the PC to seatalkng? The data is available on the network so I should be able to use it.
Can anyone offer some information or experience with this.
