HLK-WIFI-RS232M01 is a WLAN Module based on UART Serial from Hi-Link.



1.1. Main Function



_ Support for UART data serial, four baud rate options: 19200 / 38400 / 57600 / 115200bps.



_ Wireless data rates support the 802.11b Standard, the maximum rate is 11Mbps.



_ Integrate the functions of 802.11 MAC protocol Software.



_ Support for the STA appliances in the Infrastructure Network.



_ Support for the OPEN/WEP mode authentication.



_ Support for the wep64/wep128/ccmp/wpi data encryption transmission in the



shared key mode



_ Support for the automatic networking mode and manual networking mode.



_ In the automatic networking mode,the module can automatically scan the



target network, and automatically connect when disconnection.



_ In the manual networking mode,operation of connect and disconnect is touched off by



order,this supports a flexible control space.



_ Support the network data transmission in RAW/UDP/TCP format.



_ Support seven groups of the basic parameters set, and can connect to seven target



networks the most.



_ Support to configure the parameters through user serial.



_ Support to upgrade the firmware on line by the internet.








1.2. Typical Applications



1.2.1. Wireless POS Machine



In a Wireless Bus System based on the WLAN technique, carheld or handheld



POS machine in each bus equips with a h-WiFi module, and AP is fixed in the Bus



Terminus. When buses reach the terminus, wireless POS machine always does the



identification automatically, then connect to the AP, and Operational Data in POS



machines is uploaded to Data Center Server in Bus Terminus through AP.



1.2.2. Wireless Monitoring and Control System



Serial devices networking(TCP/IP) has been a trendy of Industrial-site



networking, but Field wiring and the following construction, transformation cost often



become a bottleneck of serial devices networking. WLAN modules embed in these



Monitoring and Control Terminals ,which support serial ,not only can absolves the



difficulty of wiring, but also reduces the construction cost, and it especially adapts to



the devices about Industrial Environment and Factory Automation Systems, Site



Monitoring System and etc.
