AIS to PC from standard horizon 2100

Hi in simple terms how can I get the AIS info from the VHF into my PC to show on PC plotter?

Assuming you don't have a serial port, you need a USB to Serial RS232 Adapter Cable. Don't buy a cheap one, I have been through about 4 different types.

If you only have one device to feed into the PC, I recommend this:

If you may want to add other devices (GPS, SeaTalk, NMEA etc) get a twin version:

These both use the FTDI chipset with COM Port Retention, which makes setting up a bit easier as the device remembers which COM port it is assigned to; most don't.

Then you just connect up via a 9-Way D-Type socket which you can wire up, or you can cut open a double ended cable like this:

Thanks for the reply Nigel.
Sorry to be thick but what pins do I connect to with the NMEA data from the VHF?

... what pins do I connect to with the NMEA data from the VHF?

You mean on the D-9 socket? Receive Data (2) and Ground (5).

See here: http://www.dataip.co.uk/Reference/Serial9DPinOut.php note that there are very small numbers next to the pins/sockets.
