About the NMEA datagram formats
The TV80 can send and receive information to and from several different peripherals.
All transmissions take place as
datagrams
with data sentences. Each datagram has a
defined format and length.
The NMEA 0183 standard is the most common protocol used to receive and transmit
data to and from peripheral sensors. A parametric sentence structure is used for all
NMEA data.
The sentence starts with a “$” delimiter and represents the majority of approved
sentences defined by the standard. This sentence structure with delimited and defined
data files, is the preferred method for conveying information.
For more information about the NMEA standard, the format and the data sentences, refer
to NMEA’s official publications. The
NMEA 1083 - Standard for Interfacing Marine
Electronic Devices
document explains the formats in detail. The document can be
obtained from NMEA.
Note
The terms "Datagram" and "telegram" are generally used to describe the basic transfer
unit associated with a packet-switched network. In this publication, we use the term
"datagram".
