Standard NMEA 0183 communication parameters
The TV80 system uses both NMEA and proprietary datagram formats to communicate
with peripheral systems and sensors. The majority of the datagrams used by the TV80
system are defined by the National Marine Electronics Association (NMEA). NMEA has
defined a fixed set of transmission parameters.
The communication parameters defined for NMEA 0183 are:
•
Baud rate
: 4800 bit/s
•
Data bits
: 8
•
Parity
: Even
•
Stop bits
: 1
Some instruments may provide other parameters and/or options. You must always check
the relevant technical documentation supplied by the manufacturer.
