In Mode, you choose how the Autopilot’s WiFi operates. By default, the Autopilot is set to function as a WiFi Access Point Master (AP).
When you select Master (AP), the option Managed (Client mode) becomes available. In Managed mode, the Autopilot connects to an existing WiFi network, such as a router, BoatController, OpenPlotter, or a similar system.
In Master (AP) mode, this is the name of the WiFi network broadcast by the autopilot as an access point — by default, pcnautic_AP.
In Managed (Client) mode, enter the SSID of the existing WiFi network that the autopilot should connect to.
In Master (AP) mode, we strongly recommend setting a password to prevent unauthorized access to your system. The password must be at least 8 characters long.
In Managed (Client) mode, enter the password of the existing WiFi network the autopilot should connect to.
In Master (AP) mode, leave this field empty.
In Managed (Client) mode, enter the static IP address you want the autopilot to use within the network.
An IP address consists of four numbers separated by dots, for example: 192.168.14.1.
Note:
The first three numbers must match the network you’re connecting to.
The last number must be a free address within that range (between 1 and 254) not already used by another device.
If your network supports DHCP, you may leave this field empty, and the autopilot will automatically obtain an IP address.
Displays the current IP address of the ControlHead.
After making any changes, always click Submit to save and apply the settings.
If you are using a Realtek RTL8153 USB LAN adapter, an Ethernet section will appear on this page.
Here, you can set the mode of the LAN adapter:
DHCP Client (default): The adapter automatically receives an IP address from a DHCP server in the network.
DHCP Server: The adapter assigns IP addresses to devices connected via Ethernet.
You will also see the current IP address assigned to the LAN adapter, depending on the selected mode.
If the autopilot is connected to the internet via WiFi, this connection can be shared with wired network devices by setting the Ethernet mode to DHCP Server.
Conversely, a wired internet connection via the LAN adapter can be shared with WiFi clients, provided the WiFi mode is set to Master (AP).
Although these are USB devices, they are handled internally as serial devices.
In this section, you can set the type of connected serial devices, such as our remote control receiver. Only serial devices that are not automatically recognized will be listed here and can be configured manually.
For each device, you can choose from the following modes:
Remote – Select this if it is a Pcnautic Remote Receiver.
NMEA OUT – Sends NMEA data from the autopilot to the external device.
NMEA IN – Receives NMEA data from an external device, such as a GPS receiver or wind sensor.
Some NMEA routers or systems cannot connect to the Autopilot directly. In such cases, the Autopilot must connect as a client to the external system.
To do this, enter the IP address or hostname and port number of the external system in the fields provided. In most cases, these fields can be left blank.
Don’t forget to confirm your changes by clicking the Submit button.
Note: If you are not using an NMEA client, leave the above fields empty to avoid unnecessary delays.
At the bottom of the page, you’ll find an overview of the so-called IP leases of connected (WiFi) clients. For each device, the following information is displayed:
IP address
MAC address
Hostname
Lease expiration time
When your smartphone connects to the Autopilot via WiFi (in Master (AP) mode), it will typically lose its mobile data connection (4G/5G), even though the mobile network is available. This is standard behavior: smartphones prioritize WiFi over mobile data, even if the WiFi network has no internet access.
If you want to be connected to the Autopilot and the internet at the same time, you can switch the Autopilot to Managed (Client) mode and let it connect to your phone’s personal hotspot instead.
Mode: Select Managed (Client).
SSID: Enter the name of your phone’s WiFi hotspot.
Key: Enter the password of your phone’s hotspot.
Client Mode Address:
Leave this field empty if your phone supports DHCP (this is usually the case).
Or enter a static IP address within the phone’s network range (e.g., 192.168.43.100 for Android or 172.20.10.5 for iPhone).
On Android:
Go to Settings > Network & internet > Hotspot & tethering.
Enable Wi-Fi hotspot.
Take note of the network name (SSID) and password.
On iPhone:
Go to Settings > Personal Hotspot.
Enable “Allow Others to Join”.
Take note of the network name and password.
Make sure the Autopilot is within range of your phone’s hotspot signal.
The Autopilot connects to your phone's WiFi hotspot.
Your phone stays connected to the internet via 4G/5G.
You can access the Autopilot's web interface from your phone using its local IP address, while maintaining internet access on your phone.
