Digital Yacht ZDIGSTNUSB SeaTalk 1 to USB Converter Interface

The Digital Yacht ZDIGSTNUSB is a compact, bi-directional SeaTalk 1 to USB converter that bridges legacy Autohelm and Raymarine SeaTalk networks with modern PC-based navigation software. Whether you're running Windows, Mac, or Linux, this interface provides a reliable, high-speed USB 2.0 connection to your onboard SeaTalk 1 data network.

The SeaTalk protocol, originally developed by Autohelm in the early 1990s, was used on virtually all Autohelm and Raymarine instruments, MFDs, and autopilots through approximately 2012. With Raymarine's own SeaTalk-to-NMEA converter (E85001) discontinued, the ZDIGSTNUSB offers a modern, supported solution for thousands of boats still running SeaTalk 1 networks.

Key Features:

• Bi-directional conversion between SeaTalk 1 network and USB interface
• Full multi-transistor SeaTalk 1 interface for reliable data transfer
• High-speed USB 2.0 interface compatible with Windows, Mac, and Linux
• Bus-powered — draws power directly from the SeaTalk network (no separate power supply needed)
• Supports special Raw Data mode ($STALK) for developers and advanced users accessing raw SeaTalk data
• Compatible with open-source navigation projects supporting $STALK protocol
• Compatible with Autohelm and Raymarine SeaTalk 1 instruments, MFDs, and autopilots

An ISO version (ST-NMEA ISO Converter) is also available separately for direct NMEA 0183 network connections. The ZDIGSTNUSB is the ideal solution for boaters who want to bring their SeaTalk 1 instrument data into navigation software on a laptop or onboard computer without replacing existing hardware.
