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.
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
