NMEA Operation

This radio supports NMEA0183 version 4.01.

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 2.0 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.

xx Status:RMC > GLL > GNS > GGA

xx Latitude/Longitude:RMC > GLL > GNS > GGA xx UTC Time: RMC > GLL > GNS > GGA > ZDA xx Date: RMC > ZDA

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

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