Raymarine In-Line SeaTalkNG Terminator

The Raymarine In-Line SeaTalkNG Terminator (Part Number A06074) is a critical network termination component designed for Raymarine's SeaTalkNG digital communication system on extended cable runs. This terminator prevents signal reflection and data corruption in marine navigation networks where cable lengths exceed standard distances, ensuring clean signal transmission across your vessel's integrated electronics system.

The SeaTalkNG protocol operates as a differential pair system requiring proper impedance termination at network endpoints. Without correct termination on long cable runs—particularly those extending beyond 60 feet—signal reflections create noise that degrades data integrity between chartplotters, autopilots, transducers, and other networked marine instruments. This in-line terminator absorbs reflected energy at the network's end node, maintaining signal quality and system reliability. The compact design (1 x 1 x 2 inches) allows discreet installation without cluttering your console or retrofit requirements.

Anglers running multi-device setups across larger vessels—offshore sportfishermen with distributed transducer arrays, trawler operators managing equipment across multiple cabin stations, or cruisers extending autopilot connections below deck—benefit from this terminator when network topology demands longer cable segments. It's equally essential for retrofit installations where factory cable routing limits placement options. Whether you're upgrading an existing Raymarine network or troubleshooting intermittent communication between devices, this terminator resolves the signal integrity issues that generic marine wiring cannot address.

The SeaTalkNG standard represents Raymarine's full-duplex marine networking backbone, linking modern chartplotter, sounder, and autopilot systems into unified displays. Proper network termination is foundational to system performance—skipping or incorrectly placing a terminator compromises every connected device, not just the network endpoint. This component replaces the earlier A80001 terminator, offering continuity with legacy Raymarine systems while supporting current product generations.
