[TG] [TG11] E7 and furuno 588

[Tom - Raymarine - Moderator]

Hello Mim,

There's a reference for what NMEA0183 messages the e7 can send/receive in Appendix B (p411) of the Lighthouse v19 Operating instructions which can download from our online handbook resource at http://www.raymarine.com/manuals-documents/.

The TLL message is designed for carrying information about (to quote the NMEA0183 spec) "Target number, name, position and time tag for use in systems tracking targets" (by implication and standard usage, Radar ARPA targets) rather than waypoints or other marked geographic locations. The e7 supports TTM (the equivalent of TLL using range and bearing relative to your own vessel rather than geographic lat/lon) but not TLL.

Raymarine systems don't make a distinction between 'marks' and 'waypoints', and waypoints can be transferred into Raymarine Lighthouse 2 or 3 displays in the following ways:

• over Raynet (ethernet) from another Raymarine display
• from a MicroSD card, in standard GPX file-format
• Synched over Wifi from the Navionics Boating app
  

You can also share the currently-active waypoint (Goto) over NMEA2000 or NMEA0183 (on displays that support this obsolete interface), but this is not stored in the Raymarine display: it's live/active navigation data only.

Regards,
Tom
