The SeaTalk(R) <-> NMEA Bridge is a stand alone single chip computer, that translates information between SeaTalk and NMEA. It can read & write NMEA and read & write SeaTalk data.
(SeaTalk is registered trademark of Raymarine Ltd. Raymarine)
Baudrates for USB port and NMEA ports can be adjusted seperately from 300 to 38400 Baud.
Here is a simple example on what you can do with the SeaTalk NMEA Bridge. Connect your SeaTalk Instruments and your NMEA Network Have data from SeaTalk devices and from NMEA device combined on your board computer.

These are just two verry simple examples. With the SeaTalk NMEA Bridge you will many functions and features that haven't been possible before.
Additionally to the standard SeaTalk -> NMEA conversion, the bridge software offers a new - NMEA like - command $STALK.
With the command $STALK,xx,yy,zz the PC can send any SeaTalk command you like. Your PC just sends a simple text string, and the bridge handels the spezial 9-bit protocoll, the collision detection and the electrical connection to the SeaTalk bus. ( Either with your own software or with a standard terminal programm )
With this new command a normal pc or notebook can send any SeaTalk command and so it can control or manage SeaTalk devices. ( Example : Switch Illumination of SeaTalk instrument on/off, Change Display units from mph to knots and and and )
This special function is also available the other way arround.
The bridge can send every SeaTalk datagram as a $STALK,xx,yy,zz string to the PC. This simple text string can be read and computed by the pc and so we can read information from the SeaTalk Bus, that have no corresponding NMEA sentence.
( Example : see above )
The bridge comes with a printed manual and USB drivers.
It is used for research on data communication, computer communication and data conversion with computers and instruments on board of boats.
It must not be used as the main source for navigation information
The user allways must to use charts and other conventional navigation aids.
To make sure that the SeaTalk-NMEA-Bridge is what you need, please read the manual before ordering.
