RL80C upgrade to axiom

[Chuck - Raymarine - Moderator]

Joe,

Q. The GPS antenna on the boat is a raymarine external antenna purchased new and installed about 5 years ago. The marina could not determine the model without taking apart the top, so I elected to hold off. However, I would like any clarification you can provide. Specifically, does the axiom support both an internal antenna and an external antenna? Do I need an external antenna if the axiom is under a hard top? Do you think a 5 year old raymarine will connect to the axiom? Obviously, if I don't need it, problem solved.
A. During the period which you have identified, both the Raystar 125 and its successor, the Raystar 130, were offered. The Raystar 125 GPS Sensor may be adapted for use with Axiom MFDs. Like the Axiom MFDs, the Raystar 130 GPS Sensor featured a SeaTalkng / NMEA 2000 communications interface, permitting each of these products to be interfaced as spurs to a powered and properly terminated SeaTalkng backbone.
