Make sure that at least one network card is installed on the PC. The PC is connected to the monitor through the network
card.

Connect one end of the network cable to the network card slot of the PC and the other end to the hub slot.

then insert the network upgrade tool component to the main unit interface of N1 in the same way as the

the same time.

To enter the upgrade mode, follow this procedure:
Use the network upgrade tool component to connect to the network for upgrade. Power on N1, and N1
automatically enters the upgrade interface.
