What to do with YELLOW cable?

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum snfriends,

Please click here to view a FAQ addressing the leads found within a SeaTalkng Spur Cable. As you can see, the spur cable's extra lead is a SeaTalk data lead. This lead would come into play when connecting a device supporting SeaTalk communications protocol to a device supporting both SeaTalk and SeaTalkng/NMEA 2000 communications protocols (but not both simultaneously) such as an i70S MFID or p70S Autopilot Control Head. When used to interface devices which will be communicating via SeaTalkng communications protocol, this lead is not used. Accordingly, should your system feature only devices supporting SeaTalkng / NMEA 2000 communications protocol, then this lead would not be used and may simply be insulated to prevent shorting.

Please additionally note that the maximum permissible total length for a spur is 6m.
