Thanks again JohnD.
Interesting comparison between Raymarine and Garmin. Garmin simply produce and sell the desired cable.
Raymarine, while acknowledging that their products can interface with a computer, don't seem to want to provide the kit to do it. From their site I get the impression that they are more concerned about warranty breaches than helping customers connect.

Question
Is it possible to connect the DB9 connector of the GPS 112LP NMEA version to my COM1 serial port of my Sony notebook?
Answer
First, I just want to clarify the fact that the 112LP GPS sensor with NMEA output does not ship from the factory with a DB9 serial connector attached. There are several outfits who have been selling these units online, however they have been modified AFTER being shipped from Raymarine. These alterations are not authorized by Raymarine and can void the sensor's warranty.
That being said, yes it is possible to connect the 112LP to the COM port of your PC. You will need to supply the GPS sensor with a source of 12V DC power, as the COM port does not provide any power to external devices.
If you are constructing an adapter to do this, you will need to gain access to the red, yellow, and shield wires in the 112LP cable. The 112LP yellow conductor will connect to pin 2 of the DB9. The 112LP shield will connect to pin 5 of the DB9. The shield also doubles as the 12V DC (-) connection. Red is the 12V DC (+) connection.
The NMEA protocol is 4800 baud, 8 (8 bits), N (no parity), 1 (1 stop bit). You may need to adjust this in the port setup on your Sony notebook. Flow Control can be set to "hardware".

Hmm. I just want a cable. So have sent a specific request to Raymarine asking them to supply one.
If this fails I guess the only solution is to make one up a la John D.
Seems clear though that the desired outcome of interfacing and exchanging data with the GPS300 is perfectly possible.
