• Integrated smartAIS with SOTDMA: Proactively warns of collision threats with voiced alerts and crossing information; broadcasts heading data so others can identify your direction.
• Crystal-clear audio: Delivers up to 85 dBA of loud, intelligible voice and alert audio for real-time communication on the water.
• Cortex H1 handset: Features a touchscreen, click-wheel, and dedicated keys for easy one-handed operation.
• Remote vessel monitoring and control: Use Cortex apps on a compatible smartphone to monitor boat systems, receive alerts, and remotely control devices.
• NMEA 2000 networking: View Cortex data on connected MFDs and chartplotters for unified aboard situational awareness.
• Multi-station and expansion: Cortex M1 hub with tethered H1 handset; add more handsets to extend reach and control on board, plus wireless Wi-Fi linking to the hub.
• Cortex network capacity: Supports up to 5 handsets directly, plus 5 through an existing boat network for larger vessels.
• DSC direct calls: Tap the AIS vessel symbol to hail other vessels quickly in urgent situations.
• Voice prompts and signaling: Replace ambiguous bells with clear voice prompts; preset horn signals or loudspeaker announcements via any Cortex handset or the Cortex Onboard app.
• Rugged, user-focused design: Intuitive screens and step-by-step data flows help you stay in command during critical moments; reliable audio power and proactive alerts keep you informed.
• Operational specs: IPX7 water rating; H1/H1P operate at 12–24V; current draw up to 6A max, 700 mA nominal; wide operating temperature range for demanding conditions; VHF TX/RX coverage and performance tuned for real-world use.
