of addresses: A, B, and C.
Subnet mask
The mask is a 32-bit number corresponding to an IP address. Some of these numbers are 1, and the
others are 0. The mask can divide the IP address into two parts: the subnet address and the host address.
The part of the IP address corresponding to the 1 bit in the mask is the subnet address, and the other bits
are the host address. The mask for class A addresses is 255.0.0.0, the mask for class B addresses is
255.255.0.0, the mask for class C addresses is 255.255.255.0.
Gateway
The default gateway in the host is usually called the default route. The default route (Default route) is the
route chosen by the router when no other route exists for the destination address in the IP packet. All
packets whose destination is not in the router's routing table will use the default route.
DNS
The IP address of the DNS server. DNS Server part is where you can specify the IP Address of your
Preferred DNS (Domain Name Server) and Alternate DNS. When the device uses a static IP address, the
user is required to fill in this item, 8.8.8.8(Google) will be a good choice. If a specific DNS server is not
used, the default gateway IP address is generally sufficient.
The configuration will save to flash memory after clicking Save button. All configurations take effect after a system reboot.
3.2.3. Serial port settings
The serial port module includes: serial port parameter configuration, network parameter configuration. The main function of the serial
device server is to carry out two-way transparent transmission of standard serial bus data (RS-232, RS-485, RS-422) and standard
Ethernet data supporting TCP/IP protocol to solve common serial equipment Networking problems on the Internet. The Port
configuration page can configure the parameters of the serial port and socket, as shown in Fig.29. Details on work mode connectivity
protocols and its settings of N5X0 series are given in
Operation modes, this section will only focus on the part of
parameter description. The description of the configuration parameters on this interface is shown in table 13 and table 14.
