Frequently Asked Questions (FAQ) – Expert Insights
Q: What display sizes and resolutions are available in the ONWA K-Astral Series?
A: The K-Astral is available in an 8.0-inch (800×600 pixels) and a 12.1-inch (1024×768 pixels) sunlight-viewable color TFT display delivering 1000 nits brightness with multi-touch capacitive glass engineered to track wet fingers and reject accidental palm touches.
Q: What electronic nautical charts are compatible with the ONWA K-Astral MFD?
A: K-Astral supports C-MAP DISCOVER X, C-MAP REVEAL X, C-MAP MAX, Navionics+, and ONWA’s proprietary K-Chart 2.0 and K-Chart 3.0 vector cartography loaded via dual front-facing MicroSD card slots.
Q: Can the K-Astral MFD display both CHIRP sonar and radar simultaneously?
A: Yes. Models designated with the ‘X’ suffix (K-Astral 8X and K-Astral 12X) incorporate both internal CHIRP fishfinding hardware and radar processing, allowing split-screen chart, radar overlay, and multi-spectrum sonar views simultaneously.
Q: What is the transmission power of the built-in AIS transponder on K-Astral 8A and 12A?
A: K-Astral ‘A’ and ‘X’ models integrate an internal 5W Class B+ SOTDMA (Self-Organizing Time Division Multiple Access) AIS transponder, offering higher RF transmission power and faster reporting rates than conventional 2W Class B CSTDMA units.
Q: Does the K-Astral connect to existing vessel NMEA 2000 CAN bus networks?
A: Yes. The unit features a certified NMEA 2000 Micro-C port plus dual optically isolated NMEA 0183 ports, enabling full telemetry exchange with GPS compasses, engine gateways, wind anemometers, and autopilots.
Q: Where can I purchase the ONWA K-Astral MFD with local warranty in Dubai?
A: Seanav Marine is an authorized distributor stocking the ONWA K-Astral series at Dubai Maritime City (DMC), offering regional warranty, bench testing, on-vessel commissioning, and express courier dispatch across the UAE and GCC.
