&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;'''NMEA 0183''' (or '''NMEA''' for short) - is a combined electrical and data specification for communication between marine electronic devices such as echo sounder, sonars, anemometer (wind speed and direction), gyrocompass, autopilot, [[GPS]] receivers and many other types of instruments. It has been defined by,&lt;br /&gt;
and is controlled by, the U.S.-based [http://www.nmea.org/ National Marine Electronics Association]. &lt;br /&gt;
&lt;br /&gt;
The NMEA 0183 standard uses a simple ASCII, serial communications protocol that defines how data is transmitted in  a &amp;quot;sentence&amp;quot; from one &amp;quot;talker&amp;quot; to one &amp;quot;listener&amp;quot; at a time.  Through the use of intermediate expanders, a talker can have a unidirectional conversation with multiple listeners, and using multiplexers, multiple sensors can talk to a single computer port. Third-party switches are available that can establish a primary and secondary talker, with automatic failover if the primary fails. &lt;br /&gt;
&lt;br /&gt;
At the application layer, the standard also defines the contents of each sentence (message) type so that all listeners can parse messages accurately.&lt;/div&gt;</summary>
