When working normally, you can directly connect the equipment to the network by using the
network cable. When initialization and fault detection are needed, it can be directly connected to the
PC through the network cable. When the equipment is running, the network port indicator lights up,
so it can be judged whether it has been connected to the network and the rate of access to the
network.
Users can change the IP address of the network port, but the MAC address cannot be changed.
If you want to connect multiple devices to the network side, the external network device must
keep the same network segment as the network port of the device, and there is no IP and MAC
address conflict.
The port pins are defined as follows:

Note: KPS/KGW3224A series equipment supports configuring RS485 serial port in
RS422 mode. When the RS-422 serial port N is enabled, the RX 2n indicator will always be
on, indicating that the RS-422 serial port N has been turned on. At this time, RX/TX(2n-1)
is the serial port indicator of RS-422 port n.
