The Airmar Noland RS11 converts tachometer and analog sensor signals into NMEA 2000 messages, making engine data readable on chart plotters and other multifunction displays. Two RPM inputs and six analog inputs let it handle one or two engines from a single unit. Configuration and calibration are handled through Windows PC software connected via USB — select which data each input converts (engine temp, oil pressure, etc.), dial in calibration values, enable sender current, manage engine hours, and set alarm thresholds. The water-resistant housing includes a gasket-sealed terminal strip cover and a plastic plug for the USB port when not in use. A multicolor status LED shows operating mode at a glance, and all inputs tolerate 30V or more without damage.
