what annoys me the most about NMEA is that the organization says it was
formed to arrive at some sort of standardization, and so NMEA 0183, and
now 2000. However, the bozos at Raymarine have decided to make
SeaTalk, just to muddy the waters. Want to connect a Garmin? Sure,
that's where the NMEA standard is supposed to work, but instead, we
have to buy a multiplexer so that these gadgets can network.


Just to set the record straight:

1. With NMEA-0183 a multiplexer is only needed when you want to connect
multiple talkers to a single input. An NMEA-0183 talker (sender) can
drive four inputs.

2. NMEA-2000 does not need any multiplexers.

Why do you think that if anyone paid $3800 for the standard, he/she would
give you a copy?
It is, after all, copyrighted material.
