3.4.2Sensor 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:

Shields

A

B

C (GND)

Talker (e.g.: GPS)

+ IN

G1 (or 2,3)

- IN

A

B

C (GND)

Listener (other equipment)

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).
