Choosing Between the Nauti-Control ST Wireless and N2K Wireless Modules

Both the Nauti-Control ST Wireless and N2K Wireless modules deliver the same powerful wireless functionality — running identical firmware but with different interface options. Each provides seamless integration with Raymarine Autopilots that support SeaTalk, SeaTalk NG, and NMEA 2000 (N2K) networks.

In most cases, the choice comes down to the type of network your instruments and autopilot use. However, in mixed systems, selecting the best option can depend on how your onboard network is configured.

Straightforward Setups

If your boat uses a SeaTalk autopilot (such as the ST1000/ST2000) together with SeaTalk instruments like the ST60 or ST40 series, the choice is simple — the ST Wireless module is designed for you.

Likewise, if your system is built around a Raymarine Evolution (Evo) or other SeaTalk NG autopilot, combined with NMEA 2000 / SeaTalk NG / SimNet instruments, then the N2K Wireless module is the natural fit.

Both systems can interface via the Raymarine SeaTalk-to-SeaTalk NG adapter, where required, ensuring complete compatibility across generations of equipment.

Mixed Network Examples

Example 1: SeaTalk Autopilot with N2K Instruments

If you have an ST2000 autopilot but also use NMEA 2000 or SimNet instruments and a GPS/chartplotter, either module could work — depending on your wiring preference.

Using the ST Wireless:
Connect the ST Wireless module to the SeaTalk side of the Raymarine adapter. N2K data will be translated through the adapter to SeaTalk, while autopilot commands are transmitted directly over SeaTalk.
This is a common and effective configuration, especially if your primary goal is autopilot control without full instrument data sharing — in which case, the adapter may not even be required.
Using the N2K Wireless:
Connect the N2K Wireless module to the N2K / SeaTalk NG side of the adapter. In this setup, autopilot commands pass through the adapter, while live data flows natively over N2K.
If you want both instrument data and autopilot control, this configuration is often preferable and offers a cleaner plug-and-play installation using standard drop cables.

Example 2: Evo Autopilot with Legacy SeaTalk Instruments

In a less common but still possible setup — for instance, an Evo 1 autopilot paired with older SeaTalk instruments — both modules remain viable.

The Raymarine SeaTalk Converter will handle the necessary translation between networks (SeaTalk ↔ SeaTalk NG / N2K).

If your primary interest is controlling the Evo autopilot and you plan to modernise your instruments in the future, the N2K Wireless is the more future-proof choice, allowing easy expansion into a full NMEA 2000 system later.

Summary

System Type	Recommended Module	Notes
SeaTalk autopilot with SeaTalk instruments	ST Wireless	Direct integration, no converter required
SeaTalk NG / N2K autopilot with N2K instruments	N2K Wireless	Native plug-and-play connection
Mixed system (SeaTalk autopilot + N2K instruments)	Either	Use Raymarine adapter to suit connection preference
Evo autopilot + legacy SeaTalk instruments	Either (prefer N2K)	N2K module provides better long-term flexibility
