Yacht Devices YDNM-02 NMEA 0183 Multiplexer 5 x NMEA0183, SeaTalk

The NMEA 0183 Multiplexer YDNM-02 is a smart multiplexer featuring five NMEA 0183 ports and one SeaTalk port, designed for easy configuration with a simple button press. Despite its advanced features, the multiplexer remains user-friendly and quick to install, requiring only a paperclip for setup.

Key Features

• Easy Configuration: Six configuration presets with different port speeds and routing schemes, selectable by a hidden button.
• Auto-Detection: Ports can auto-detect the speed of connected equipment, simplifying the installation process.
• Flexible Routing: Ports can be routed to themselves, allowing multiplexing of data from SeaTalk and up to five NMEA 0183 talkers to multiple listeners.
• Customizable Settings: Adjust speed, routing, data filters, and tunnel mode for each preset via commands sent to any port of the multiplexer.

Product Features

• NMEA 0183 Ports: 5 ports (2 x TX/RX, 1 x TX/RX with galvanic isolation 2500 VRMS, 2 x RX only).
• SeaTalk Port: Supports connection of multiple devices.
• Connection Types: Supports both "single ended" (RS-232) and "differential" (RS-422) NMEA 0183 connections.
• Speed Configuration: NMEA ports configurable for any speed from 300 to 115200 bps, including AUTO speed.
• Data Conversion: Bi-directional data conversion between SeaTalk and NMEA 0183 with autopilot support.
• Data Filters: Individual filters on all ports for incoming and outgoing messages by datagram number, sentence formatter, or talker ID.
• Routing Rules: Individual routing rules for all ports, with support for routing NMEA 0183 ports to themselves.
• Tunnel Mode: Connects old, non-standard, and Navtex equipment.
• Firmware Updates: Supports updates from the serial port.

Installation Tips

When installing the Multiplexer, choose a dry mounting location to prevent seawater from causing a short circuit. Despite the waterproof case, the terminals are open. The Multiplexer can be fixed in any orientation using the supplied screws and the two screw holes (4 mm diameter, 72 mm between centers).
