[CA] [CA11] AIS data to Axiom from Standard Horizon VHF

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Spring33,

There are two incorrect assumptions which you have made in the method which you have used to interface the VHF radio to the Raymarine system

1) SeaTalk1 communications supports AIS data ... it does not.

2) Raymarine / Raytheon branded NMEA 0183 to SeaTalk data bridging devices support 38400 BAUD NMEA 0183 communications and bridging of VDO and VDM NMEA 0183 AIS data sentences ... only 4800 BAUD communications data rate is supported by Raymarine / Raytheon branded NMEA 0183 to SeaTalk data bridging devices and VDO and VDM NMEA 0183 AIS data sentences are not bridged by these devices to SeaTalk.

Instead, it is generally recommend that an Actisense NGW-1-ISO-AIS NMEA 0183 to NMEA 2000 data bridging device be used to interface such VHF radio / AIS receivers to the system's powered and properly terminated SeaTalkng / NMEA 2000 backbone.
