Hi Fourgeau, & welcome to Cruisers Forum!
You would find it valuable (for yourself) if you learned a bit about connecting NMEA
devices together. It's not rocket science.
In short, the output from your GX2100 is using NMEA-0182 (or -0183). This is not
compatible with USB but is
compatible with some
USB-to-Serial converters. This is a small dongle with a 9-pin serial
port on one end & a USB plug
on the other, & it should come with some driver software
for your laptop. You can then run the output from your GX2100 into a 9-pin serial plug
, which will then plug into the USB/Serial converter plugged into your USB port.
There are some gotchas along the way. NMEA-0182 uses 0-5v signaling. RS232
Serial uses +/- 9v signaling. But a good quality Serial to USB converter will
work for NMEA
. I use a KeySpan & have had no problems for 4 years, but poor quality serial/USB converters on other boats have caused me many headaches.
The output from older GX2100s was weak & needed some help (pull-up resistors). I'll let someone more knowledgeable about the GX2100 help you further if you still want to tackle this yourself.
