4. Product function introduction

IP address refers to the Internet Protocol address, indicating the identity of the module in the LAN.The IP address is

unique in the LAN and therefore cannot be duplicated with other device addresses on the same LAN.E810-DTU

(CAN-ETH) supports static IP and DHCP IP acquisition methods.

Static IP: Static IP is required to be manually set by the user. During the setting process, note that the IP, subnet

mask and gateway are simultaneously written.Static IP is suitable for LAN communication without DHCP Server or

fixed IP address.

DHCP: DHCP is mainly used to dynamically obtain IP address, Gateway address and NDS server address

information from gateway host (with DHCP server). By DHCP, users can save the tedious steps of setting IP address

manually, and avoid the conflict of IP address in LAN caused by setting IP address manually.

The subnet mask is a type used to indicate which network the host indicated by the IP address is in. The subnet mask

cannot exist separately. It needs to be used together with the IP address. Its role is to divide an IP into two parts: the

network address and the host address.

The subnet mask is a 32-bit address. For a class A address, the default subnet mask is 255.0.0.0, the default subnet

commonly used class C address, the capacity of IP in the subnet is 2

mask for class B is 255.255.0.0, and the default subnet mask for class C is 255.255.255.0. For example, for our

addresses in the IP address, the number of IP available in class C subnet mask is 254.

Gateway, also known as Inter-Network Connector, realizes the interconnection between two networks.If the device

is connected to a router, the gateway is the router IP address.Through the gateway,the device can access another network

(or local area network) connected by the gateway.
