4.3 Connecting Ethernet Port
The Ethernet port is a standard RJ-45 port. With its self-adaptation function, it can be automatically
configured to full duplex/half-duplex operation mode. It supports MDI/MDI-X self-recognition of the
cable, allowing you to use a cross-over cable or straight-through cable to connect the terminal
device to the network device.
