3.4.2 Sensor Hardware Installation
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).
