- 24 -
The HF2221 device Ethernet interface work in router mode. When connect to router, it will get IP
address from router (as picture 192.168.1.100). The product itself generate a subnet (10.10.100.254
default). The device from the Ethernet interface is assigned with IP address by module
(10.10.100.101). The device and the PC1 are in the same subnet for network communication. A
connection fro PC1 to PC2, but PC2 cannot actively connect to PC1.
Figure 22. Ethernet Interface Function 1 (Router)
The HF2221 device Ethernet interface work in router mode. Default Ethernet 2 is WAN which is used
to IP addres s(as figure 192.168.1.100 ). Default Ethernet 1 is LAN, and the device itself constitute a
subnet (10.10.100.254 default). The device IP is assigned by module(as figure 192.168.1.100).

Ethernet Port Bridge Function
Figure 23. Ethernet Port Function1 (Bridge)
The HF2221 device Ethernet interface work in bridge mode. When connect to router, it will get IP
address from router (as picture 192.168.1.101). AT the whole network, the product is like an invisible
device. PC1 ad PC2 can communicated mutually without any constraint. But if product needs to
connect with other devices, it needs set LAN IP address (192.168.1.10 as picture)
