Optionals for indicators and sensors for boats:
Server with RS232 or NMEA 183, AUX interface Amplified speed indicator

PC Server  

The system allows, easily and cheaply, to interface a series of marine instruments with analogic indication to any personal computer system equipped with analogic indications to any personal cpmputer system equipped with a normal serial interface RS232.

In standard configuration the system allows to acquire:
- speedometer
- anemometer
- wind direction indicator

Besides, two additional analogic inputs are available for other types of instruments. The serial interface to the PC is standard type RS232, or it is possible to mount a standard interface RS485, which allows to connect on serial bus up to 32 cascade systems.
The procedure used is in conformity with NMEA 183 standards.
