Cortex® Monitoring- Custom Sensors and Relays

Cortex® Custom sensors and relays

With the Cortex™ M1 hub, you can monitor a variety of internal sensors, NMEA inputs from other devices on board, as well as hard-wired GPIO (General Purpose Input/Output) interfaces for up to five sensors.

Two of these can be control interfaces for remotely turning on a relay. For example, these could be connected to a door opening or motion sensor, high water or bilge pump activation sensor, smoke or heat sensor, or AIS stealth button.

Built-in Monitoring

The Cortex itself includes its heading, barometric, and battery voltage sensors – all of which are also available to the monitoring system. (Please note that GPIO cannot monitor voltages over 17-volts.)

M1 SENSORS

HEADING Internal use only

BAROMETER Update rate 1Hz max (averaged)

BATTERY VOLTAGE Measured at a power input

EXTERNAL SENSORS INPUTS 5 Inputs, Digital (0-24V), Analog (0-17V)

NMEA data from other devices can be shared with Monitor if the Cortex is connected to NMEA 2000 bus.

• Water depth
• Water temp
• Barometric pressure
• Vessel heading
• Vessel speed
• Wind data

Sensors must be wired before the sensors can be used by Cortex. Refer to the Install manuals for the Hubs (M1 and V1).

To understand how to program sensors, see: Program GPIO sensors with the Cortex Onboard App.

Some products that can be used as sensors for GPIO monitoring:

• Bilge Pump with a float switch
• High Water sensor
• Door or Hatch Alarm
• Smoke or Heat Detectors
• Low voltage Motion detector
