Cortex® M1, SOTDMA SmartAIS Transponder with Remote Vessel Monitoring
RELAX. CORTEX IS ON WATCH FULL-TIME.
The Cortex M1 hub combines advanced collision avoidance technology with proactive alerting plus remote monitoring and control of onboard systems from your compatible smartphone.
A high-speed smartAIS transponder transmits your boat’s location and heading and proactively warns of certain collision threats.
In addition to collision alerts, smartAIS will trigger alarms for anchor drag or man overboard situations.
This hub comes VHF-ready. Simply add a Cortex handset (sold separately) for full VHF radio capability.
Cortex apps let you monitor boat systems, receive alerts and remotely control devices from your compatible smartphone.
A GPIO port and supplied cable allow you to monitor bilge pumps, security sensors, shore power and more.
NMEA 2000® networking allows you to view Cortex data on your connected MFDs and chartplotters.
Smart logic AIS helps you make better decisions.

COLLISION AVOIDANCE
Cortex M1 is a full Class B SOTDMA transceiver combining GPS, AIS and heading data with smart logic to proactively warn you of certain collision risks with alarms or voice-annunciated alerts that escalate until acknowledged. AIS vessel information (name, bearing and relative position) is continuously provided using AIS information broadcast from other boats.

ANCHOR WATCH
Using actual anchor position from the bow and the Cortex built-in heading sensor, smartAIS tracks boat movement and sounds an alarm if the anchor drags or if there is a change in wind speed, direction or water depth. While on your boat, get alerts on your compatible mobile device via the Cortex Onboard app — or via the Cortex Monitor app when you’re ashore.

MAN OVERBOARD
Cortex smartAIS continuously watches for man overboard (MOB) activations, sounding an alarm when it detects one. MOB can be manually activated via the Cortex Onboard smart device app or automatically from an AIS MOB beacon — which launches a track-back mode for quicker retrieval.

DIRECTIONAL VOICE ALERTS
In the event of a collision alarm, Cortex will announce the direction of a collision threat, such as “collision alert, starboard bow.” Instead of an ambiguous beep that other AIS systems provide, Cortex tells users what the alert is for and the direction of the threat.

MONITORING AND CONTROL
Check boat status, receive alerts and control devices with Cortex remote monitoring access using Cortex handsets (sold separately) or Cortex smartphone apps. Directly connect up to 5 external sensors to your system for added monitoring capability.

CORTEX MONITOR APP
Subscribe to a premium Cortex Monitor plan to receive alerts, see real-time information about your boat and remotely control devices such as air conditioning, lighting, refrigeration or ice makers using the Cortex Monitor app on your compatible smartphone.

CORTEX ONBOARD APP
While you’re on your boat, the Cortex Onboard app can serve as your primary interface with your Cortex M1 hub, allowing you to monitor boat stats, receive alerts, view instrument data and display AIS screens on your compatible smart device.

MAKE YOUR INTENTIONS CLEAR
Broadcast built-in heading via AIS transmissions to other vessels so they can more accurately track their closest point of approach and alter course to avoid you.

NETWORK CONNECTIVITY
Cortex can receive and broadcast information over NMEA 0183 and NMEA 2000 networks, making it compatible with the majority of modern chartplotters and multi-function displays.
Robust technology for harsh marine environments.

RUGGED, DURABLE DESIGN
Water-rated to IPX7 standards, the Cortex hub’s thermal polymer housing is heat- and corrosion-resistant — so it can be safely mounted nearly anywhere onboard.

LOW POWER CONSUMPTION
Engineered for minimal power consumption at just 500mA, the Cortex hub can stay on full-time to keep you informed. It will alert you even when your MFD is turned off — ideal if you need to conserve power when anchored or on a long voyage.

GALVANIC ISOLATION
Galvanically isolated ports and internal components protect your Cortex hub and connected equipment from electrical shorts and circuit damage in the corrosive marine environment.

MULTI-CONSTELLATION GNSS
With fast 10Hz GPS updates that keep up with your vessel, your vessel position is plotted using multiple global satellite networks. When you connect other devices to your Cortex GPS using NMEA 2000 or NMEA 0183, all onboard equipment benefits from Cortex’s super-fast GPS capability.
Peace-of-mind monitoring and connectivity.

Monitor Systems
See status and history of built-in and connected sensors. Monitor bilge, security, power and other instruments. Set alarms and alarm thresholds, review data history and know when the sensor was last active.

BUILT-IN SENSORS
GPS, heading sensor, battery sensor and barometer provide valuable out-of-the-box information on and off the boat as soon as you plug in and configure your Cortex system.

NETWORKED SENSORS
Simply connect to your boat’s NMEA 2000 network to monitor1 factors such as wind speed and direction, or water depth from your other onboard devices.

EXTERNAL SENSORS
Your imagination is the limit —connect with sensors to monitor bilge activity and level, shore power, security systems and more (external sensors sold separately).

CORTEX MONITOR APP
Download the Cortex Monitor app from the Apple® or Google™ app store and use your smartphone or tablet to monitor your vessel and receive alerts1.

GEO-FENCING
Drawing upon the strength of the Cortex Monitor smart-device app and relying on the information being broadcast from your boat, know where your boat is — and if it’s where it should be1. Get an alert if it moves outside a designated area.

CONTROL DEVICES
Connect with the Cortex Monitor app to remotely control devices such as lights, air conditioning and ice makers on your boat by connecting them to your Cortex system.

REAL-TIME UPDATES
Cortex sends updates to the cloud, allowing you to receive status information and alerts directly on your compatible smartphone or tablet.

MONITOR LITE
A Monitor Lite subscription is free with Cortex. View twice-daily updates on your Cortex system. See alarms from within the Cortex Monitor app.

MONITOR PREMIUM
See real-time updates on the Cortex Monitor app. Receive instant alarm notifications and control onboard devices. Access advanced features like geofence and Anchor Watch. Monitor Premium is available on a monthly or annual subscription.

NMEA GATEWAY
Cortex can receive and broadcast network data — or translate it between NMEA 0183 and NMEA 2000. This makes it compatible with devices on either of those networks — plus it can link via built-in Wi-Fi® connectivity. Receive alerts directly on your compatible devices from anywhere onboard.

CONNECT TO ROAMING
Connect to a boat network with cell or satellite data to roam where Cortex cellular data connectivity cannot reach.

MONITORING MADE EASY
Register your compatible smartphone or tablet with Cortex Monitor, pairing it to your Cortex hub. Then use the Cortex Monitor app to remotely monitor your boat through built-in and connected sensors to your Cortex hub. Upgrade to a Premium subscription to get access to Anchor Watch and receive real-time push notifications.
Maximum performance, minimal effort.

EASY TO GET STARTED
Connect Cortex Onboard and Cortex Monitor apps easily with your unique QR code to start receiving alerts, viewing boat status information and remotely controlling devices with your compatible smartphone.

SOFTWARE UPDATEABLE
Cortex will only get smarter. New features and functionality are being developed all the time and are automatically downloaded to the Cortex Onboard app for easy Wi-Fi updates to your Cortex system.

SIMPLIFY YOUR SYSTEM
Cortex replaces up to 10 disparate devices with a single integrated hub device, making it a simple, easy to install and intuitive device to use.

BUILT-IN SPLITTER
Install Cortex and retain your existing antenna and VHF radio. Cortex features a built-in high-performance no-loss VHF/AIS splitter with a fail-safe pass-through. Simply connect your existing VHF to the auxiliary output on Cortex.
