HF2221 Serial Server Device User Manual 2. HARDWARE INTRODUCTION The HF2221 unit is a complete solution for serial port device connecting to network. This powerful device supports a 10/100BASE-T Ethernet connection, a reliable and proven operating system stored in flash memory, an embedded web server, a full TCP/IP protocol stack,and standards-based (AES) encryption.
HF2221 Serial Server Device User Manual Table 2. HF2221 Interface Definition Function Name Description External 10/100M Ethernet Ethernet 1 Interface LAN function 10/100M Ethernet Default is WAN function in AP mode (Can be Ethernet 2 configured to LAN Function), connect to router LAN port for network access.
HF2221 Serial Server Device User Manual 2.2. RS232 Interface Device serial port is male(needle), RS232 voltage level(can connect to PC directly), Pin Order is cosistent with PC COM port. Use cross Cable connected with PC(2-3 cross, 7-8 cross, 5-5 direct, 7-8 no connection), see the following table for pin defination.

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.
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.
HF2221 Serial Server Device User Manual Figure 13. STA Application 3.1.3. AP+STA Wireless Network HF2221 can support AP+STA method. It can support AP and STA interface at the same time shown as follow: http://www.iotworkshop.com - 18 -...
HF2221 Serial Server Device User Manual Figure 14. AP+STA Wireless Network In this picture, HF2221 open the AP+STA function and the STA interface can be connected to the remote server by the router. Similarly, the AP interface can also be used. Phone/PAD can be connected to the AP interface and to control the serial devices or set itself.
AP and STA parts must set to the different sub-network. 3.1.4. IOTService Software Open the IOTService after connect to the AP hotspot generated by HF2221 or PC and HF2221 connect to same router (WAN port connect to router LAN port). Then configure the parameter.
Figure 17. STA Scan Parameter 3.1.5. Webpage Configuration Use PC to connect with HF2221 through its AP SSID (IP:10.10.100.254) or PC and HF2221 connect to same router (WAN port connect to router LANN port, IP is assigned by router). Type the product IP, default username and password: admin/admin) to login the webpage to configure the parameter.
HF2221 Serial Server Device User Manual Figure 19. STA Scan 3.2. Ethernet Interface Function HF2221 provides with a 100M Ethernet interface. Through the 100M Ethernet interface, user can achieve the connection among WIFI, serial port and Ethernet port. http://www.iotworkshop.com - 22 -...
3.2.1. Ethernet Port with Wi-Fi Figure 20. Ethernet Interface Function (AP) HF2221 servers as AP and generate a central network. The IP addresses of all the devices and modules are in the same network segment. 3.2.2. Ethernet Interface Router Function Figure 21.
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).
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).
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.
