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
Data bits
Parity
Stop bits
Data amplitude
Drive capability
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.
• Status:RMC > GLL > GNS > GGA
• Latitude/Longitude:RMC > GLL > GNS > GGA
• UTC Time: RMC > GLL > GNS > GGA > ZDA
• Date: RMC > ZDA
• 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 fol-
-
lowing format.
