PRO NMEA 0183 Multiplexer – 5 Inputs & 2 ISO-Drive Outputs, Ethernet & Serial Connections

The PRO-NDC-1E is more than just an NMEA 0183 Multiplexer

Rugged, Robust, type-approved multiplexer with powerful, advanced features enables baud rate adjustments, auto-switching, and sentence-level filtering.

Features:

• Auto-switching between inputs to allow for a primary, secondary, and tertiary priority input.
• Configurable baud rates to allow 38400 and 4800 baud devices to operate through the same multiplexer.
• Sentence filtering to block unwanted sentences from specific outputs helps to limit bandwidth consumption.
• Easy to configure using the web-based UI, no need to manually enter and edit strings of text.
• RINA type-approved device means the multiplexer is fit for leisure, commercial, and class/type installations.
• Multiple LEDs allow for quick glance diagnostics to ensure everything is operating correctly.
