3.7 Sensor Hardware Installation:
3.7.1 Installation of an RS422 serial interface:
In most cases, the output from a GPS is already being used by existing navigation equipment.
It is possible to split an RS 422 output for two devices. If the signal becomes too low, then an
NMEA splitter has to be used.
Example for single talk multi-listener connection:
Each interface on the Transponder is a RS422 serial interface
The shield or ship main ground should not be connected with the signal ground (GND).
