External WiFi Antenna installation
External WiFi Antenna installation
• Connect the WiFi Antenna to the Cortex Hub port labeled WiFi.
• Hand tighten clockwise. Do not over torque.
• Adjust the angle of the WiFi antenna to be as close to vertical as practical.
Install the WiFi Antenna last to allow sufficient room for fingers to first access and
install the other SMA size connectors attached to the External GPS and optional
cellular antenna for cloud connectivity.
Installations where an Cortex Hub is mounted in close proximity to an H1 (with little
or no interference to the WiFi signal) may not require fitment of the External WiFi
Antenna.

NMEA 2000 Gateway
The Cortex Hub incorporates an NMEA Gateway to allow different brands and
generations of electronics on NMEA 0183 or 2000 networks to talk to each other
automatically and transfer data without extra multiplexing devices or configuring.
The Gateway translates selected NMEA 2000 sensor data for compatibility with
mobile apps. Monitor navigation data on your Cortex Onboard App on your phone
or tablet or use it with third party apps of your choice.
Data is made available to NMEA 0183 and 2000 plotters. The Gateway supports
a range of wind, depth, speed, heading, temperature, barometric pressure and
autopilot PGNs.
See PGNs sent and received by the gateway (pg26).
Example Case #1:
Sailing and navigation apps cannot talk directly to an NMEA 2000 network as the
apps use the 0183 protocol. We need to translate data from NMEA 2000 to 0183.
Gateway: The Cortex Hub receives NMEA 2000 PGNs and automatically converts
these to 0183 sentences and sends to devices running the sailing and navigation
apps via WiFi.
Example Case #2:
A vessel has an older chart plotter (NMEA 0183 only) with new NMEA 2000 sailing
instruments.
Gateway: The Cortex Hub receives the new instrument data from the vessel’s NMEA
2000 network and automatically converts the data to 0183 sentences for the chart
plotter. The chart plotter 0183 wires are connected to the 0183 wires on the Cortex
Hub’s input/output cable.
