Connecting to a Raytheon Autohelm System
The optimum way to connect Navigator to a Raytheon Autohelm
system is to use the Direct SeaTalk Interface, Raymarine Part No.
E85001 (Figure A-2). You can also use a Z290 SeaTalk-to-NMEA
converter for this connection; however, keep in mind that not all
SeaTalk features are supported by the Z290. Therefore, to ensure
full communications, we recommend that you use the Direct SeaTalk
Interface.
To connect directly to a Raytheon Autohelm system, refer to
Figure A-1 and Table A-5.
