NMEA OPERATION

This radio supports NMEA0183 version 3.01.

NMEA Input

If you have difficulty getting your radio to receive data from your GPS receiver, check the

device’s configuration. It should be set to the following parameters:

Baud rate 4800 bps

Data bits 8

Parity None

Stop bits 1

Data amplitude Over 3.0 V

Drive capability Over 10 mA

The radio supports RMC, GLL, GNS, GGA and ZDA sentences. When these sentences are

received, the radio displays latitude/longitude, date, time, course, and speed. If any

sentence except an RMC or GLL sentence is received, the radio uses the information based

on the following priority order.

x Status:RMC > GLL > GNS > GGA

x Latitude/Longitude:RMC > GLL > GNS > GGA

x UTC Time: RMC > GLL > GNS > GGA > ZDA

x Date: RMC > ZDA

x Speed / Course:RMC

# NOTE 1: If the radio receives only a GLL sentence, the radio does not display the current

speed, course, and date.

# Note 2: If the radio receives both RMC and GLL sentences, the radio uses only the RMC

sentence.

# Note 3: Status data is used to check whether the GPS data is valid or invalid.

NMEA Output

When the radio receives a DSC call (Distress, Position Reply, or Position Send), it outputs a

DSC/DSE sentence from the NMEA output port.

# NOTE: When the radio receives a distress call, it outputs a sentence in the following

format:

x $CDDSC,12,3081234000,,07,00,0354013946,0657,,,S,E*6D

$CDDSE,1,1,A,3081234000,00,60875646*13
