CruzPro NC-20/8 NMEA To RS232 Data Converter

The CruzPro NC20 NMEA combiner accepts up to 4 or 8 channels of
NMEA (and/or RS232) serial data at 4800 BAUD and combines these
signals onto one RS232 compatible output line at either 4800 or
9600 BAUD.

The NC20 can handle any mix of NMEA and RS232 input signals at
4800 BAUD and multiple units can be daisy-chained for more inputs
than 4 or 8 channels.

The input signal level can be as low 1.6 Vp-p and as high as -20
to +22 VDC without damaging the instrument. The output level is
RS-232 compatible -10 to +12 VDC.

The 4 channel version of the NC20 draws less than 0.05 amps and
the 8 channel version draws less than 0.08 amps.

The NC20 output can be fed to a variety of different NMEA
enabled instruments such as chart plotters, computers, radar
screens or remote data repeaters such as the CruzPro RP30 and/or
RP110
