Flexible multiplexing with preconfigured versions for
Autoswitching or AIS operation.
The Actisense NDC-4 NMEA Multiplexers 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.
The Actisense NDC-4 and NDC-4-USB allow up to five
OPTO isolated NMEA 0183 sources to be multiplexed into a single
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). Two flexible ISO-Drive outputs allow two different
downstream talker baud rates to be created, ensuring maximum system
flexibility.
5 OPTO-Isolated NMEA 0183 Data Inputs allowing the input to
work correctly with long cable runs, and/or in a noisy
environment
2 ISO-Drive Flexible Outputs fully compatible with the RS422
(NMEA 0183), RS485 and RS232 connections on the NMEA listening
device(s) the NDC-4 supplies data to, and offers total galvanic
isolation of up to 1500v between the output and ground
NMEA and PC (USB/ISO-Drive) Outputs
Powerful Processor - the ARM 32-bit microcontroller is capable
of 40 million instructions per second, with very large NMEA data
buffers to allow smoothing of short-term peaks in the NMEA data
flow
Flash Upgradeable
Combine Mode: Intelligent Software filters the valid data from
all active inputs, using the configured Inclusion lists, and then
combines the remaining data using a simple priority system
Autoswitch Mode: Intelligent Software determines the highest
priority device with valid data
Very Low Current Consumption - ideal for small vessels with
small batteries.
Diagnostic Tri-Colour LED that indicates current operation
mode, volume of data being multiplexed, or if a hardware fault has
been detected
IP66/IP68 Case and Gland Design - a very robust polycarbonate
case with a high waterproof certification
High Quality Angled Screw Terminals that make cable
installation a simple and quick operation
