Raymarine A80493 Y-Cable 25 pin to 9 pin and 7 pin

The Raymarine A80493 Y-Cable 25 pin to 9 pin and 7 pin is a critical integration component for anglers and boaters running modern Axiom RV chartplotter systems. This multi-transducer connector exists because serious fishermen and navigation-focused boaters need simultaneous data from multiple sonar sources—pairing advanced DownVision imaging with traditional Airmar transducers in a single network. If you're running a high-end Axiom glass and want full sonar redundancy plus the clarity of DownVision side-scan, this Y-cable is the backbone of that setup.

The cable features a 25-pin backbone connector that splits into separate 9-pin and 7-pin outputs, allowing simultaneous connection of CPT-1xx DownVision transducers and CP370-style Airmar transducers without compromise or daisy-chaining complexity. The engineering here is straightforward but essential: one cable eliminates the need for multiple adapters or switchboxes, reducing clutter in the helm and cutting potential failure points. At 1 lb, it's lightweight and designed for permanent marine installation, with connectors rated for saltwater environments where corrosion and intermittent connections sink fishing days and compromise navigation safety.

This cable is purpose-built for Axiom RV systems and is mandatory if you're upgrading from single-transducer to dual-source sonar on a modern Raymarine glass network. Freshwater and saltwater anglers, commercial fishing operations, and serious cruising boaters benefit most—especially those who've already invested in an Axiom RV display and want to layer DownVision performance over existing Airmar hardware. Installation is plug-and-play: connect the 25-pin connector to your chartplotter's transducer port, then plug both transducers into their respective outputs. Verify connector orientation before power-up to avoid shorts; Raymarine connectors are keyed, so forced connections are the only real risk.
