NoMachine is used to remotely access the desktop of the P450 onboard computer from a Windows computer. This section covers only the basic procedure for establishing a remote connection through the LQ communication link.

Connection information

Onboard computer IP: 192.168.1.11
Username: amov
Password: amov

Download and installation

  1. Open the official NoMachine download page.
  2. Download the NoMachine client for Windows.
  3. Double-click the installer and follow the prompts to complete the installation. If the installer requires you to restart the computer, restart it before continuing.

Preparation

  1. Power on the UAV and the LQ remote controller.
  2. Follow Prepare the communication link to establish the network connection between the computer and the LQ remote controller (the recommended computer IP address is 192.168.1.123).
  3. Open Windows Terminal or Command Prompt and enter:
ping 192.168.1.11

Open NoMachine only after you begin receiving continuous replies. If the request times out, the computer is not yet connected to the onboard computer. Check the Ethernet cable, LQ link, and computer network configuration first.

Create a remote connection

  1. Open NoMachine and go to the Machines (Computers) page.
  2. Enter 192.168.1.11 in the search box and select the option to connect to that host. Alternatively, click Add to create a connection manually.
  3. When creating a connection manually, complete the fields as shown in the table below:
Setting Value
Name P450 (or another easily recognizable name)
Protocol NX
Host 192.168.1.11
Port 4000
  1. After saving, double-click the connection.
  2. When a host authenticity or fingerprint confirmation prompt appears during the first connection, verify that the target IP is 192.168.1.11, and then confirm to continue.
  3. On the login page, enter:
    • Username: amov
    • Password: amov
  4. Click the login button and wait for the onboard computer desktop to appear.
  5. When connecting for the first time, guidance for display resolution, audio, or interaction methods may appear. Select the options you need and continue.

Disconnect the remote connection

After completing your work, select Disconnect from the NoMachine menu. Disconnecting the remote desktop usually does not close programs already running on the onboard computer. Before closing a terminal, stopping a script, or shutting down the computer, confirm whether the current function is still running.

Caution

The remote desktop provides direct control of the onboard computer. Do not delete system files, modify unknown settings, stop services related to flight controller communication, or arbitrarily stop running programs while the UAV is in flight.

Troubleshooting sequence when unable to connect

  1. Confirm that the UAV is powered on and that the onboard computer has finished starting up.
  2. Confirm that the communication link between the computer and the LQ remote controller is working properly (see Prepare the communication link).
  3. Run ping 192.168.1.11 to check network connectivity.
  4. Check that the host address is 192.168.1.11, the protocol is NX, and the port is 4000.
  5. Check that both the username and password are the lowercase word amov.
  6. If the ping succeeds but NoMachine cannot establish a connection, wait for the onboard computer to finish starting up and try again. If the connection still fails, record the error message and contact after-sales support.
