The Actisense NDC-4 and NDC-4-USB allow up to five OPTO isolated 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.

The NDC-4 is flexible and powerful enough to be the heart of a simple system, or one of many Actisense products in a more complex system. It provides complete access to all NMEA 0183 data sources, configurable filters to remove unwanted data, 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) or as an Autoswitch (NDC-4-ASW).

*Four inputs on the USB version, as the USB interface acts as the fifth channel, overriding the fifth OPTO input.

Benefits of the NDC-4 versions:

• Multiplex up to five NMEA 0183 devices
• Filter unwanted data
• Five flexible versions available (NDC-4, NDC-4-USB, NDC-4-ASW, NDC-4-AIS & NDC-4-AIS-USB)
• Preconfigured versions for AIS and Autoswitch operation
• USB kit (NDC-4-USBKIT) converts an NDC-4 to an NDC-4-USB
