4.2 Local network parameters
4.2.1 Local IP
STATIC (Static IP): Users can define configuration IP, subnet mask, default gateway, domain name resolution server
(DNS server);
DHCP (Dynamic IP Acquisition): The device logs in to the server to automatically obtain the IP address, subnet mask,
gateway address, and DNS server address parameters assigned by the server and configure and use
4.2.2 DNS (Domain Name Resolution)
When the user enters the domain name, the DNS server will be automatically queried, the database will be retrieved by
the DNS server, and the corresponding IP address will be obtained. In the static IP mode, the user can customize the
domain name resolution server, which is used to resolve the private domain name server data. In the dynamic IP mode
The device automatically follows the domain name resolution server configured by the routing device. Users only need
to modify the DNS server of the routing device without configuring the device.
4.2.3 Network disconnection and reconnection cycle
When the device detects that it is disconnected from the server, it periodically initiates a reconnection request. Therefore,
the "disconnection reconnection time" does not affect the connection establishment time under normal conditions. The
user can customize the configuration request period, and the default is 5s.
4.2.4 Timeout restart (no data restart)
The device monitors the data sending and receiving status. If the device does not send and receive data for a long time,
the device automatically restarts to ensure the stability of long-term work. The default turn-on period of this function is 5
