0183 to 2K Wind Converter FEATURES • Interfaces NMEA-0183 Wind to 2K • Push-button to set wind DIR = 0 • Screw terminals for 0183 termination for mast and deck cabling • Plugs directly into 2K • Powered from 2K The A5905 passes the wind information from a NMEA0183 masthead device—such as the Autonnic A5120—to the NMEA 2000 bus devices. The wind data is repackaged from the 0183 to a 2000 format. In this way a masthead unit can be installed with easily cut cable threaded through the mast and deck and terminated with a screwdriver to the terminals provided. The power for the wind device is taken from the 2000 bus. In addition, a button is provided which send a message to the masthead to set its direction to zero. It is intended that he boat is heading into wind when this button is pressed—for a minimum time of 5s. This is a one-time operation and the value is retained until the button is pressed again.

A5905 NMEA-0183 WIND TERMINAL CONNECTIONS SCREW Example connection to Autonnic A5120 wind sensor. Wiring description The A5120 has a single-ended output and an isolated two-wire input. The same applies to the A5905 converter. This means that the A5120 output + is connected to the A5905 input + but the input – must be connected to GND. Similarly, the A5905 output + is connected to the A5120 input + but the A5120 input – must also be connected to GND. NMEA 2000 PGNs Output PGN Standard Windspeed and Direction (PGN:130306) at 10 per second Input PGNs Custom (PGN: 127257). A 6-byte block of...
