[CA11] e7D/950AIS/NGW-1-ISO-AIS/Em-trac wiring - dhiggins286 - 10-08-18 03:20 PM
Just purchased the NGW-1-ISO-AIS suggested on your site. Can you supply me with a wiring diagram? I want to be sure everything is correct before applying power. Thanks.

Welcome to the Raymarine Forum dhiggins286,
Should the third party AIS receiver or transceiver feature a NMEA 2000 communications interface, then it would be considered to be a best installation practice to interface the AIS receiver or transceiver to an a/c/e/eS/gS-Series MFD via NMEA 2000 communications protocol rather than NMEA 0183 communications protocol. This recommendation is based upon the fact Raymarine's MFDs are not designed to bridge AIS data received from a NMEA 0183 talker to NMEA 2000. Moving forward with interfacing the MFD to the AIS receiver/transceiver would prevent any of the systems's other devices on the SeaTalkng / NMEA 2000 backbone which were also capable of displaying AIS data from having access to AIS data.
That said, to interface the NGW-1-ISO-AIS to the NMEA 0183 interface of and a/c/e/eS-Series MFD, then it would be recommended that
- the MFD's NMEA 0183 IN2+ lead (orange/white) be interfaced to the NGW-1-ISO-AIS's NMEA 0183 OUT+/TX+ lead (white), and
- the MFD's NMEA 0183 IN2- lead (orange/green) be interfaced to the NGW-1-ISO-AIS's NMEA 0183 OUT-/TX- lead (blue),
- the AIS receiver/transceiver's 38400 BAUD NMEA 0183 OUT+/TX+ lead (orange/white) be interfaced to the NGW-1-ISO-AIS's NMEA 0183 IN/RX+ lead (red), and
- the AIS receiver/transceiver's 38400 BAUD NMEA 0183 OUT-/TX- lead (orange/green) be interfaced to the NGW-1-ISO-AIS's NMEA 0183 IN-/RX- lead (black).
