This
ZNC-580 NMEA Combiner (NMEA Multiplexer) combines up to 8 NMEA-0183 input data and
let out
it through 2 NMEA-0183 output ports and 1 RS-232 port. This is
very useful for any equipment such ECDIS and VDR required receiving various NMEA-0183
data from many devices (multiple talkers – single or multiple
listeners environment).
ZNC-580 NMEA Multiplexer has the function of NMEA data filtering for each input and
output port.
This
allows to filter out unwanted NMEA data and reduce the traffic
combined NMEA data output.
1. Features
˛
Combine
enough 8 NMEA input data and output it through 3 independent output
ports.
˛
All input
and output ports have its own “Filter table” for either passing or
filtering NMEA data. This allows to filter out unwanted NMEA data and
reduce the combined NMEA data output.
˛
If error
rate of each input data exceeds pre-defined error rate, audible and
visible alarm is on. This alerts to do preventive maintenance, and
the system reliability can be upgraded.
˛
One RS-232
serial port is available for connection to a personal computer or
other RS-232 device.
˛
Easy
configuration through RS-232 port with using PC and standard program
such Hyper-terminal.
˛
All NMEA
input ports are opto-isolated for fully compliant with NMEA-0183
standard, and protected from over voltage.
