A multiplexer built into the transceiver manages both 4800 and
38400 baud rates. This feature effectively frees up an NMEA port
on your multi-function display (MFD). if only one NMEA0183 port
exists on your equipment, the multiplexer eliminates the need for a
separate multiplexer.
Typically the NMEA0183 connections are used as follows:
• The 4800 baud wires connect to the appropriate points on the
VHF radio or other NMEA0183 4800 baud input/output device.
• The 38400 baud wires connect to appropriate Raymarine MFDs.
The NMEA0183 port on each MFD connected in this manner
must be set to 38400 baud.
3.4 Cable shielding
Ensure that all data cables are properly shielded that the cable
shielding is intact (e.g. hasn’t been scraped off by being squeezed
through a tight area).
