NMEA0183 Multiplexer YDNM-02

Description

NMEA0183 Multiplexer YDNM-02 is a smart multiplexer with five NMEA0183 ports and one Seatalk 1 port. It can be easily configured with just a click of a button and includes filtering and routing rules to be applied.

The multiplexer has been designed to be extremely easy to configure with just the use of a paperclip to select from up to 6 preset configurations.

If you find no suitable preset, you can change any setting of any preset: speed, routing, data filters or tunnel mode. This can be done with a command sent to any port of the Multiplexer. In the settings you can also lock the button to prevent incidental switching of the preset by incompetent crew.

Users Manual

When deciding where to install the Multiplexer, choose a dry mounting location. Despite the fact that the Multiplexer case is waterproof, the terminals are open and seawater can cause a short circuit. The Multiplexer can be fixed in any orientation using the two screw holes (4 mm diameter, 72 mm between centers) and the screws supplied.
