The Marine Data MD72RDI is a compact, 3-face panoramic analog rudder angle indicator manufactured in the United Kingdom by Marine Data Systems Ltd.. Engineered for overhead deckhead or bulkhead mounting in wheelhouses where wide-angle visibility is essential, the 250 mm diameter unit features three separate viewing windows with illuminated moving pointers graduated in 5° increments from 45° Port to 45° Starboard.

The indicator accepts digital NMEA 0183 serial rudder sensor angle ($RSA) sentences from compatible rudder angle transmitters (such as the Marine Data MD61) with automatic baud rate detection. Housed in a robust jet-black powder-coated aluminum alloy enclosure, the MD72RDI supports both local rotary push-control dimming and remote NMEA dimming, and includes automatic signal-loss warnings with self-recovery without requiring a manual reset.

Key Features:
• 3-Face Panoramic Analog Display: Three wide-angle viewing faces graduated in 5° increments from 45° Port to 45° Starboard for clear visibility across the bridge.
• Illuminated Moving Pointers: High-contrast pointer and scale illumination with local rotary encoder push control and remote dimming compatibility.
• NMEA 0183 ($RSA) Interfacing: Automatically detects baud rate and decodes standard digital NMEA 0183 Rudder Sensor Angle data.
• Signal Fault Warning & Auto-Recovery: Provides automatic warning upon loss of valid rudder angle data and automatically resumes operation once valid data returns without a reset.
• Flexible VESA 100 Mounting: Mounts directly to the deckhead or via the included VESA 100 bracket for angled adjustment, with dual-indicator support for twin-rudder vessels.
