My initial impression of the converter itself, upon unboxing, was one of compact utility; it felt robust and designed for a marine environment, devoid of unnecessary frills.

This small, black box was the key to keeping my tried-and-true electronics integrated, and the immediate sense of relief was palpable. It promised to solve a significant technical hurdle without requiring a complete system overhaul.

Real-World Testing: Putting Raymarine SeaTalk1 to SeaTalk NG Converter to the Test

My testing environment was primarily the interior of my sailboat, specifically the navigation station where the core of my electronics reside, and then out on the water during typical coastal cruising conditions. The converter was installed in-line with the existing SeaTalk1 backbone, connecting to a SeaTalk NG backbone with a simple drop cable. This setup was straightforward, requiring no specialized tools beyond basic marine electrical connectors and a crimping tool.

The initial setup and integration were surprisingly seamless. Once wired correctly, the converter immediately began passing data. I experienced no initial surprises or quirks; the ST60+ instruments registered on the new SeaTalk NG network as if they had always been part of it. Performance held steady across a range of conditions, from calm harbor testing to choppy offshore sailing where instrument readings are critical.

After several months of consistent use, this converter has proven to be an indispensable part of my navigation system. The durability is evident; it has withstood the occasional vibration and slight humidity inherent in a marine environment without any degradation in performance. Maintenance is virtually non-existent, which is ideal for any marine equipment. When compared to other “workaround” solutions I’ve encountered in the past for integrating older electronics, this dedicated converter is far superior in its reliability and ease of integration.

There are absolutely no signs of wear and tear on the unit, which speaks to its robust construction. The seals seem to be holding up well against occasional salt spray and condensation, a common concern for electronics mounted below deck.

Maintenance is practically zero, which is exactly what you want from a component like this. A quick visual inspection is all that’s typically needed. Compared to some patch solutions I’ve used in the past, which often required frequent recalibration or experienced intermittent failures, this converter’s reliability has been exceptional.

Breaking Down the Features of Raymarine SeaTalk1 to SeaTalk NG Converter

Specifications

The Raymarine SeaTalk1 to SeaTalk NG Converter, bearing the MFG # E22158, is a compact solution designed to bridge two distinct Raymarine data networks. It interfaces select original SeaTalk1 devices with the newer SeaTalk NG networks, enabling them to communicate and share data. This is crucial for upgrading parts of an existing marine electronics suite without replacing every component.

The primary function of this device is protocol conversion. It takes the data packets from older SeaTalk1 devices and reformats them into the NMEA 2000-compatible SeaTalk NG standard. This means sensors like the ST40 displays, ST60+ instruments, and older Raystar 125 GPS sensors can feed information into a modern system.

Its compact size is a significant advantage, allowing it to be installed unobtrusively within an electronics panel or bulkhead. The black color is standard for marine electronics, blending in with other components. It requires power from the SeaTalk NG network, which is typically supplied by the backbone power inserter.

Performance & Functionality

The core job of this converter is to enable communication between different generations of Raymarine marine electronics, and it performs this task admirably. It effectively translates the proprietary SeaTalk1 protocol into the more widely adopted SeaTalk NG standard, allowing older sensors to function seamlessly with newer displays and navigation systems. This means you don’t have to replace perfectly good transducers or basic sensors just because you upgraded your chartplotter.

The performance is reliable; I’ve not experienced any dropped data packets or significant latency issues. The older instruments connected through the converter appear on the new network with the same responsiveness as native SeaTalk NG devices. This translates to accurate and timely wind data, depth readings, and GPS fixes, which are critical for safe navigation.

Its main strength is this direct, functional compatibility without requiring complex configuration. A minor weakness, if one can call it that, is its limited scope; it only converts SeaTalk1 to SeaTalk NG, and doesn’t offer any other bridging functions. It’s a single-purpose, highly effective tool for a specific integration need.

Design & Ergonomics
