Linking laptops to nav gear has never been easier.
Before we plunge headfirst (again) into the world of multiplexers with this test report, here’s a quick review of what exactly we’re talking about. If you have older instruments or a GPS networked to send information to other devices (a multi-function display, laptop, etc.), the information is likely in “NMEA 0183” format and is sent in “sentences” in a set order. For example, the NMEA sentence “$GPAAM,A,A,0.10,N,WPTNME*32” is an “arrival alarm” sentence sent by a GPS to various networked devices upon arrival at a waypoint.
