Raymarine NMEA 0183 Multiplexer allows up to 4 NMEA devices to be connected to the C or E-Series NMEA IN port. Used to connect multiple NMEA 0183 devices to NMEA 0183 input of C or E-Series display units, the NMEA Multiplexer combines the outputs of these devices into a single, consolidated data stream. This is particularly useful when connecting both a fast heading sensor and DSC radio with position reporting capability to the display.
