Prepare the communication link

This section explains how to configure the communication link so that you can connect to the Prometheus ground control station, remotely connect via NoMachine, and connect to the QGC ground control station.

Connect the LQ to a laptop

• Connect the LQ communication link directly to the computer with an Ethernet cable, and then configure the computer's network settings
• The figure below shows the LAN1 and LAN2 ports on the LQ ground unit

• The network connection for the P450_mid360 configuration is shown below Simply plug the Ethernet cable into a LAN port

• As shown below, use an Ethernet cable to connect the LQ on the remote controller to the computer

Configure the network on a Windows 11 computer

• In Windows, locate the area shown below and right-click it to open the network settings

• Left-click Network & internet settings to open the detailed configuration page

• Click Ethernet, as shown below

• Click Edit, as shown below

1. Select Manual
2. Turn on IPv4
3. Enter the IP address: 192.168.1.123
4. Enter the subnet mask: 255.255.255.0
5. Enter the gateway: 192.168.1.1
6. Enter the DNS server: 8.8.8.8
7. Save the configuration, then unplug and reconnect the Ethernet cable for the changes to take effect

Connect to the onboard computer

NoMachine allows you to remotely access the onboard computer's desktop from a laptop to monitor the program's operating status. The onboard computer has the static IP address 192.168.1.11, and both the username and password are amov.

Caution

Before connecting, complete “Configure the network on a Windows 11 computer” above, turn on the remote controller, and use an Ethernet cable to connect the LQ communication link to the computer (see “Connect the LQ to a laptop” above for the wiring method).

For detailed installation, connection creation, and troubleshooting steps, see Simple NoMachine connection tutorial.
