NDC-5 NMEA Multiplexer

The NDC-5 is more than just an NMEA 0183 Combiner/ Multiplexer; it provides an installer with a highly flexible platform that can be used to solve many NMEA 0183 interconnectivity headaches.

Powerful routing allows any of the inputs to be routed to any output, combining data if required. Advanced features allow data rate conversion, auto-switching and advanced sentence-based routing and blocking.

Where To Buy

NDC-5 NMEA Multiplexer

The configuration tool is accessible via any popular web browser using the Ethernet port, which supports both direct and network connections. Industry leading isolation is provided on all inputs and outputs as standard so that connected devices safely avoid hazardous ground loops, the number one cause of product failure in NMEA 0183 networks. This makes the NDC-5 robust enough to handle any NMEA 0183 installation.

Pluggable connectors allow new devices to be easily installed without the need to remove the NDC-5 from its mounted location. An optional professional DIN rail mounting mechanism keeps the NDC-5 secure in high vibration environments. Integrated LEDs provide feedback on basic status while advanced statistics are available via a Web Browser.
