Autoswitch up to 5 NMEA devices to your PC, Chart-plotter, Radar, Autopilot and more, with NMEA 0183 HS compatibility and ISO-Drive ...
This Actisense™ NMEA Autoswitch allows connection of up to five NMEA (National Marine Electronics Association) inputs, and autoswitches them to its two fully isolated NMEA outputs.
NDC-4 Base unit pre-configured as Autoswitch.

A robust and highly flexible NMEA 0183 Multiplexer that cures many inter-connectivity headaches! The five NMEA 0183 inputs can be routed to any of the two NMEA 0183 outputs, as well as the serial and Ethernet ports providing a highly customisable network. The bi-directional serial port and Ethernet port also allow for simple configuration and diagnostics using Actisense software. The configuration tool is accessible via any popular web browser (using the Ethernet port) so there are no PC operating system compatibility issues to contend with.
