4.2. Wireless Characteristics
4.2.1. Auto Frequency Selection Function
When W630 work in STA mode, the WIFI serial port server will adjust itself to the same channel as AP according to the
wireless channel of AP and access it.
When W630 work in AP mode, it can be set to automatic frequency selection mode, so when the W630 starts, it will
choose a better wireless channel according to the surrounding environment.
4.2.2. Security Mechanism
USR-W630 supports a variety of wireless network encryption methods, which can fully guarantee the safe
transmission of data, including:
WPA-PSK/TKIP
WPA-PSK/AES
WPA2-PSK/TKIP
WPA2-PSK/AES
Note: the WPA-PSK and WPA2-PSK passwords are at least 8 bits.
4.2.3. STA Join The Router
The search button is added to the W630 wireless terminal settings page. When you click the button, a window will
pop up to display the surrounding AP information. After selecting the router, you will return to the original page. At
this time, the encryption mode and encryption algorithm have been filled in. You just need to write the password
according to the prompt.
4.3. Socket Communication
The USR-W630 has two Socket: Socket A and Socket B. Data written to the USR-W630 serial port, USR-W630 will
automatically send to Socket A and B at the same time; data received by USR-W630 through Socket A or Socket B, are
sent through the serial port.
Socket A works include: TCP Server, TCP Client, UDP Server, UDP Client. At present, Socket B supports TCP client and
UDP client (users can connect Socket B to remote server to realize remote control of equipment). Through the
different settings of dual Socket, multiple network interconnection modes can be realized.
When Socket A work at TCP Server, up to 24 TCP Client can be supported.
4.4. UART Framing Mechanism
4.4.1. UART Free Framing Mode
When receiving data from UART, the W630 constantly checks the interval between two adjacent bytes. If the interval
is longer than a certain value, a frame is considered end, otherwise the data is received until it is greater than 4K bytes.
