Description
Description
The Actisense PRO-MUX-2 is an advanced, commercial-grade NMEA 0183 multiplexer designed to combine, route, and filter data across complex vessel navigation networks. Equipped with 8 Opto-Isolated inputs and 6 ISO-Drive outputs, the Actisense PRO-MUX-2 consolidates multiple serial data sources—including GPS receivers, AIS transponders, heading sensors, and echo sounders—into optimized streams for chartplotters, ECDIS units, and onboard PCs.
Featuring an integrated Ethernet interface and a bi-directional serial port, the device enables high-speed data streaming over TCP/IP and UDP protocols. Its web-based configuration tool allows marine engineers to easily set up advanced sentence-based filtering, input autoswitching, custom baud rate conversions (up to 115,200 baud), and live diagnostic monitoring without installing external software.

Use Case
Multiplexers are typically used to combine multiple instruments data output into a smaller number of outputs. As you can’t connect two talkers to one listener directly, a multiplexer allows for the data to be output through one talker connection.
An example of this could be on a commercial vessel with multiple NMEA 0183 GPS, wind, AIS and depth instruments. To get all of this data combined and sent to a display or converted via an NGX to NMEA 2000, a PRO-MUX-2 can be used.
With the PRO-MUX-2, the data can be filtered, passed or blocked and monitored, giving greater flexibility and control over all instrument data.
