Shared AIS/GPS on a Mac

I've read about the ability to derive GPS information from the AIS data via Shared AIS but somehow don't see that option on my Mac. I'm currently getting GPS data from a BU 353 on one port and AIS data via a Serial Gear Serial to USB converter reading data from a Horizon VHF radio. Works fine, but I'd like to save a port!
Where should I be looking for the Shared AIS?

rmez...
You don't say which OpenCPN version you are using, but if it's at least 3.2 you don't have to look anywhere.

I don't know the Horizon VHF radio but my RO4800 (Radio Ocean) VHF radio does support sending GPS and AIS messages together at its output line. So there is configured one port only at OpenCPN with 38400 baud for GPS and AIS.

Re: Shared AIS/GPS on a Mac

I am using OPENCPN 3.2. I have a Horizon Standard G2100 VHF that outputs AIS signal. To be honest, I'm not sure it also outputs GPS at the same time...
But what do you mean that I don't have to look for shared AIS?

Reuben...
Since 3.2 all the data sources are shared. No need to set anything, if the position info is in the stream from your AIS, it gets where it should. Read the manual, especially Data Connections | Official OpenCPN Homepage

Thank you...I will try again this evening.
(Of course you appreciate that Mac guys don't usually read manuals

Re: Shared AIS/GPS on a Mac

Reading the Standard Horizon G2100 VHF user manual it seems this device does not pass through the GPS data as the RO4800 VHF does. So you have to connect to your Mac the AIS data from your VHF as well as the GPS data from your GPS device.
You may ask the Horizon hotline however.

The manual shows only these NMEA0183 sequences for 4800 baud:
Input:GLL, GGA, GNS and RMC
OutputSC, DSE



and for 38400 baud:
Input:VDM (GX2000)

Output: VDM (GX2100)




So the output is AIS only.

Re: Shared AIS/GPS on a Mac

That is correct - the SH does not put GPS data on the nmea output.

Re: Shared AIS/GPS on a Mac

Of course you are all correct. I did contact the folk at Standard Horizon and they said
"Unfortunately the only data that the GX2100 sends out are DSC, DSE, and AIS.
No GPS position data is sent out."
