I will be installing new I70 wind package and EV-100 wheel autopilot working on one backbone system. Both display units: I70S and P70S came with only 1 white(spur) terminal at the back. (most of instructions I can find on the web, are showing display units with 2 spur terminals. Package came wit A06028 T PIECE and A06074 EXTENDER.
Please let me know if proposed connection on attached picture is acceptable:
1. Connect I70S with spur cable to A06074 EXTENDER
2. Connect P70S with spur to A06028 T PIECE and run backbone to 5 WAY CONNECTOR.
3. Connect A06074 and A06028 with backbone cable.
If not, could you explain or refer me to proper connections.

Welcome to the Raymarine Forum jgol,

Q. Please let me know if proposed connection on attached picture is acceptable:
A. Unlike SeaTalk and the original SeaTalkng standard, NMEA 2000 networking standards do support daisy chains. In adherence with the NMEA 2000 standard, products such as the i70S, p70S, and p70RS which were introduced to replace the i70, p70, and p70R, these new products feature a single SeaTalkng / NMEA 2000 socket.

Indeed, the proposed connection method appears to be correct. That said, should the two items shown be located within close proximity to one another, then the T-Piece shown would typically be replaced with a 5-Way Connector and the two devices would then be connected to the spur sockets of the 5-Way Connector via appropriate lengths of SeaTalkng Spur Cable. The maximum distance which a device may be located from a spur socket is 6m.

Thank you for the reply,
in that case, I think, T piece (A06028) and coupling A06075 should be replaced with
5 piece A06064 which will be conected to second 5 piece.
Please see attached picture and let me know if I'm on the right track.
Also, would you advice installing switches on power cables to ACU 100 and back bone.

jgol,

The diagram looks good. Indeed, I would recommend installation of switches as you have indicated.

Thank you Chuck,
John

You're welcome.
