The documentation for some devices may reference the NMEA 0183 and NMEA
0183-HS connections in different ways, please use the following pages to
identify how to connect the Nemo Gateway to other devices.
If it is unclear how to connect your NMEA compatible device to the Nemo
Gateway please contact the manufacture of the connecting device for additional
support.
See the “Sample Wiring” section to see how sensors should be
connected to the Nemo Gateway. Additional sample wiring schematics are
available on the support page at

NMEA 0183 / NMEA 0183-HS Listeners
The four differential opto-isolated three terminal listener ports conform to the
NMEA 0183 and NMEA 0183-HS marine electronic device network
communication standard. These ports are capable of interfacing with most fully
and partially compliant devices that are transmitting any properly formed
sentences. Only NMEA 0183 and NMEA 0183-HS devices are to be connected to
these ports.
The Nemo Gateway will receive all properly formed NMEA 0183 and NMEA
0183-HS sentences.
Each listener port is isolated from all other listener ports. Each listener is
designed for operation with a minimum differential input voltage of 2.0 Volts
and shall not take more than 2.0 mA from the line at that voltage.
The listener circuit consists of an Altec PHP03-3.81 connector followed by a 240
ohm resister on the A line followed by isolation and protection circuitry.
NMEA 0183 / NMEA 0183-HS Talkers
The two differential four-terminal talker ports conform to the NMEA 0183 and
NMEA 0183-HS marine electronic device network communication standard.
These ports are capable of interfacing with most fully and partially compliant
devices transmitting any properly formed sentences. Only NMEA 0183 and
NMEA 0183-HS devices are to be connected to these ports.
