How Many USB inputs for Open CPN?

Hi --

I have several independant systems ie open cpn for nav, auto pilot, and radar, and I am trying to make these systems talk to each other, at least on a basic level. Here is my question: Can I have more than one USB input feeding into Open cpn?

At the moment, I have my GPS feed via a USB/Serial adapter, and that works fine. However, I'd like to add AIS, and also the heading info from the Airmar heading sensor that guides my autopilot, and this is on a NMEA 2000 backbone. There are multiple options for AIS units that use USB to connect to the computer, and I believe that most will multiplex the gps data they need and pass it on to the computer, so I could combine my gps and AIS data into one usb connection. I can get a NMEA 2000 to USB adapter that would allow me to get the Airmar heading info into the computer.

At this point, I would have two USB connections sending data to the computer -- can open cpn have more than one connection of this type?

Sorry to be so long winded!

Thanks in advance for all replies!

Yes, you can have as many serial/USB connections as you need

And the connections can be Input or Output ports.
Using OCPN 4.0 will help.
There is a complete descrition how to configure the ports, message filtering and forwarding etc. in the manual.
