STNG cable branch to Raymarine SPX or ACU molded plug

Designed for navigation system integration, the STNG cable branch to Raymarine SPX or ACU molded plug R12112 provides a connection between a modern SeaTalk NG network and older SPX or ACU series equipment. This solution maintains compatibility and extends the lifespan of existing installations by integrating devices such as SPX autopilot computers or ACU control units into the NMEA 2000 network via SeaTalk NG.

Raymarine compatibility and interconnection

The R12112 cable serves as a key component for Raymarine system upgrades. While Axiom or Element chartplotters natively use SeaTalk NG, this cable connects older-generation components such as SPX-10, SPX-30 computers or ACU units, which are standard for autopilots. This interconnection is essential for boat owners looking to modernize their network without replacing all steering equipment. Unlike standard SeaTalk NG branch cables that connect recent NMEA 2000 peripherals, the R12112 provides a specific interface for SPX and ACU systems, extending their utility within a SeaTalk NG ecosystem.

Technical integration and specifications

The STNG cable branch to Raymarine SPX or ACU molded plug R12112 is a passive component designed for direct integration. It does not add active functionality but ensures data transmission between the two bus architectures. Its molded design guarantees a secure connection and resistance to marine conditions, typical of Raymarine standards. It facilitates the exchange of heading, position and other navigation data between the autopilot unit and multifunction displays or sensors connected to the SeaTalk NG network.
