Features: The Gyro Converter transforms analog gyro compasses signals into NMEA0183 digital data with 0.1° accuracy, delivering multiple channel outputs for autopilot systems, AIS devices, and marine navigation equipment. Featuring a 4 digit LED display with adjustable brightness and compatibility across 360X/180X/90X/45X/36X transmitting ratios, this converter adapts to both synchronous and stepper compasses via flexible power sourcing. Ideal for marine engineers, ship navigators, and outdoor teams requiring reliable heading data integration for radars systems or electronic chart plotters. Designed for harsh maritime environments, its weather resistant casing operates flawlessly in temperatures from 40°C to +85°C during oceanic voyages or extreme weather navigation. With IEC61162 1 compliant HDT sentence output at 4Hz frequency and 4800 baud rate, this gyro compasses converter ensures seamless interoperability with modern marine electronics while minimizing signal latency.
