Introduction
The NMEA 0183 Gateway (hereinafter Gateway or Device) allows you to connect NMEA 0183 equipment
to a NMEA 2000 network and vice versa. It has a bi-directional converter with wide support of message
types including AIS (see Appendix D) and autopilot control.
The Gateway has one NMEA 2000 connection and one NMEA 0183 port with transmit and receive
data lines. The congurable baud rate from 300 to 115200 baud of NMEA 0183 port allows connecting
AIS transceivers (38400 baud), fast NMEA 0183 multiplexers and PC adaptors, as well as standard
NMEA 0183 equipment. Both “single ended” and “differential” NMEA 0183 connections are supported
(see Section II.1).
The Device is equipped with a Micro SD card slot used for conguration, rmware updates and diagnostic
data logging. No special software is required to update or congure the Gateway. You only need a device
(laptop or smartphone) with a MicroSD card reader and simple text editor.
A exible system of lters allows blocking of NMEA 0183 messages by sentence (see Section VI.2)
and NMEA 2000 messages by PGN, sender address, or 29-bit message identier. Filters also allow blocking
of all messages in a specied direction (see example in Section VI.4).
The separate lter denes what NMEA 0183 sentences should be forwarded from the NMEA 0183 input
to the NMEA 0183 output. This turns the Device into a multiplexer of NMEA 2000 and NMEA 0183 data,
and allows using it as a repeater or extender of the physical NMEA 0183 uplink. Multiple “listeners” can be
connected to the NMEA 0183 output (TX) lines of the Gateway.
The Gateway is powered from the NMEA 2000 and provides high voltage galvanic isolation between
NMEA 2000 and NMEA 0183 ports.
