Combine multiple sources of NMEA 0183 data into a single stream.
The Actisense NDC-4 allows up to five NMEA 0183 sources to be multiplexed into a single stream*.
Two flexible ISO-Drive outputs allow two different downstream talker baud rates to be created, ensuring maximum system flexibility.
It provides complete access to all NMEA 0183 data sources, configurable filters to remove unwanted data using NDC Control Centre, as well as enabling an on-board PC to read and add the combined data stream.
Factory preconfigured versions enable the NDC-4 to be used out of the box for AIS operation (NDC-4-AIS). An ‘autoswitch’ option is also available (NDC-4-ASW) to provide redundancy options to your NMEA 0183 network.
*Four inputs on the USB version, as the USB interface acts as the fifth channel, overriding the fifth OPTO input.
