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.
- NMEA 0183 data streaming over Ethernet enables connectivity to existing Ethernet devices and systems.
- 5 OPTO-Isolated NMEA 0183 inputs and 2 ISO-Drive NMEA 0183 outputs provide protection for all connected instruments.
- Dedicated bi-directional Serial port (fully isolated utilising ISO-Drive technology)
- A serial port can be used as an additional input/output
- Ethernet port supports direct and network connections
- NMEA 0183 streaming via Ethernet
- Configurable input and output baud rates
- Allows Data combining and rate conversion
- 2 independent Autoswitch virtual inputs with priority
- Isolation from battery supply
- Diagnostic LED’s
