E-28 Uniden MHS135DSC Radio Owner’s Manual
Your radio supports NMEA0183 Version 3.01, a standard for data communication
between marine instruments. If you are connected to a chartplotter and the radio
receives another boat’s position data (sentences) in a DSC call, the radio sends the
position data to the chartplotter so you can see the location.
NMEA sentences contain different sets of data. The MHS135DSC supports the following
sentences:
DATA RMC GLL GNS GGA ZDA
UTC Time

Status (Valid/IInvalid) O O O O X

1. Connect the RED wire to the NMEA positive (+) output.
2. Connect the BLACK wire to the NMEA ground.
3. Connect the YELLOW wire to the NMEA positive (+) input.
