Page 16: Network Structure
3.1. Wireless Network HF2221 can be set as a wireless STA and AP as well. And logically, it supports two wireless interfaces, one is used as STA and the other is AP. Other STA devices can join into the wireless network through AP interface. -
Page 17: Sta Wireless Network
Figure 12. General AP Network 3.1.2. STA Wireless Network Take the following picture as example. When router works in AP mode, HF2221 connects to the user’s devices by RS232/RS485 interface. In this topology, the whole wireless network can be easily stretched. -

Page 24: Ethernet Port Bridge Function
HF2221 Serial Server Device User Manual 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). -
Page 25: Figure 24. Ethernet Port Function2 (Bridge)
Figure 24. Ethernet Port Function2 (Bridge) The HF2221 device Ethernet interface work in bridge mode. Default Ethernet 2 is WAN for connecting to the router while the Ethernet 1 is LAN to connect to the PC. PC acquire the IP address (192.168.1.101 as figure). -
Page 26: Cascade Mode
3.2.4. Cascade Mode Figure 24 Cascade Mode Devices can work as cascade to add connection nodes. Multiple HF2221 LAN and gateway address is not constraint each other (LAN1: 192.168.2.1, LAN2: 192.168.3.1 as figure). By ethernet connection, modules can acquire upper router IP address to become cascade mode. -
