[CA] [CA11] P70 Integration with Axiom Pro and SPX30

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum cdiversions,

SPX autopilots which have been updated with the latest available software may indeed be interfaced to Axiom/Axiom Pro/Axiom XL MFDs. For clarification purposes, commanding navigation (i.e. commanding Go To Cursor / Waypoint or Follow Route) from a MFD running LightHouse 3 software (ex. Axiom/Axiom Pro/Axiom XL MFDs) will not automatically engage any autopilot other than an Evolution autopilot. Within such systems, the autopilot's control head must be used to command the autopilot into Track mode after first having commanded navigation via the MFD. SPX autopilot component should not be interfaced to the system via a SeaTalk to SeaTalkng Converter. Instead, the ST70 Autopilot Control Head and SPX Autopilot Course computer must each instead be interfaced as an individual spur to the system's powered and properly terminated SeaTalkng / NMEA 2000 backbone.

SPX autopilot components must be updated with the latest available software or they may not support proper communications with MFDs running LightHouse 3 or LightHouse II software. Unfortunately, SPX autopilot components are not designed to be updated by Axiom/Axiom Pro/Axiom MFD. Should you have one of the legacy MFDs which were designed to update software within SPX autopilot components (see the SPX Autopilot Course Computer software update web page and ST70 Autopilot Control Head software update web page, then the software within these components may be updated by a Certified Raymarine Installer or by Raymarine’s Product Repair Center.

Finally, it is indeed possible to replace a ST70 Autopilot Control Head with a p70S/p70/p70RS/p70R Autopilot Control Head as long as the SPX Autopilot Course Computer has first been updated with the latest available SPX Autopilot Course Computer Software.
