Introduction
The Raymarine NMEA Multiplexer combines data from up to four
NMEA-0183 devices to provide a single, multiplexed NMEA
output.
Inputs & outputs
The NMEA Multiplexer has:
• Four NMEA inputs (listener-ports), NMEA In 1, 2, 3 & 4.
• One NMEA output (talker-port), NMEA Out
• One common terminal NMEA Out Com.
