The NMEA Multiplexer by ShipModul is distinguished by its reliability, flexibility, extensive functionality and its excellent price to performance ratio.
The multiplexer works in conjunction with both PC's and notebooks running Windows, and Apple Macintosh devices with OS-X.
Thanks to the extensive possibilities of the multiplexer, it is the optimum solution for a variety of problems, which may occur when connecting your onboard networks. You can connect the multiplexer (not just the NMEA0183) to several receivers and with each other; you also have the ability to receive and send data from modern NMEA2000 devices as well.
The options include, for example:
- Forward the outputs of multiple NMEA devices to an NMEA output or a PC
- Summarize the data from NMEA devices with different speeds on an output at a rate
- Filter NMEA records and convert between different protocols
The following settings can be customized with the configurational software:
- Filters and routing capabilities
- Prioritizing the same data from different inputs
- Conversion of protocols among themselves (NMEA0183, SeaTalk, NMEA2000)
- Variable rates of inputs and outputs from 4800 to 57600
- Conversion of records (eg: HDG -> HDT, VTG -> VHW, ...)
To protect the connected equipment from damage caused by different electrical potentials, connect the multiplexers to all ports via galvanic isolation.
The multiplexer has 4 NMEA inputs (an input can optionally used for the SeaTalk bus), 2 NMEA outputs and a USB interface.
