4. Product Function
4.1. Work Mode
W630 work mode: transparent transmission mode, serial port command mode, HTTPD Client mode, MODBUS mode,
AT command mode.
4.1.1. Transparent Transmission Mode
W630 supports the serial port transparent transmission mode, in which the data needed to be sent and received are
transparently transmitted between the serial port and WIFI / Ethernet, without any parsing, to achieve data transfer
between general serial port devices and network devices.
In transparent transmission mode, users can fully compatible with the original software platform. Users can basically
support wireless data transmission without software modification.
4.1.2. Serial Port Command Mode
In this mode, when the USR-W630 serial server acts as UDP Client or TCP Client, the user is allowed to send serial data
to different servers.
Customer MCU send packets in the following format. After the server parses the WIFI string, only n bytes of data are
sent to the destination address. When data is returned, the data is output from the serial port without parsing.
4.1.3. HTTPD Client Mode
In this mode, the user can send data to the specified HTTP server, and the W630 automatically adds HTTP protocol
header to the data sent, the content of the specific protocol header can be set by AT instructions or web pages.
This mode is used by W630 transmit data to HTTP server or to retrieve data from HTTP server. Users are using the AT
commands or webpage to set up the specific contents of the HTTP header.W630 automatically encapsulates the sent
data into HTTP protocol data and sends it to the designated HTTP server. The data received from the server will be
directly transmitted to the serial port without any processing. The tedious HTTP protocol is done by the WIFI serial
port server, which is convenient for the user to program the serial port without considering too much HTTP.
4.1.4. MODBUS TCP

MODBUS RTU
Support Modbus TCP to Modbus RTU(not support Modbus ASCII), the net parameter of module should be
Corresponding with the software, TCP server to the TCP client, port to the configuration to the same, work mode is
Modbus TCP<=>Modbus RTU.
4.1.5. AT Commands Mode
In AT commands mode, users can query the current state of USR-W630 or set the parameters of USR-W630 by sending
AT commands.

USR-W630 User Manual Technical Support: h.usriot.com
Jinan USR IOT Technology Limited www.usriot.com
18
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.

USR-W630 User Manual Technical Support: h.usriot.com
Jinan USR IOT Technology Limited www.usriot.com
19
W630 determines that after the end of a serial port, it will be forwarded to the WIFI interface.
The default 2-byte interval of the W630 is 50 ms, when the interval is greater than 50 ms, one frame ends.
4.4.2. UART Auto Framing Mode
For fixed-length data frames on the serial port, UART auto-framing can be turned on to achieve the highest forwarding
efficiency. USR-W630 serial port server supports UART port auto framing function. After setting the trigger time and
the trigger frame length, the serial server will automatically frame the data received from the serial port and forward
it to the network.
4.5. Password Authentication When TCP Establishing Connection
This function is only applicable to W630 work as TCP Server. When TCP Client connects to W630, W630 authenticates
each connected TCP.
The first data sent after TCP Client is connected should be the web page password of the W630 plus carriage return.
By default, the password of the W630 is admin, so the first data sent by the TCP Client should be "0x610x640x6D
0x690x6E 0x0D 0x0A" (hexadecimal). If the password is correct, the W630 returns "OK" instead of "NO" and
disconnects.
This function can be opened or disabled in the "TCP connection password verification" on the web page.
4.6. Register MAC/CLOUD/USR Function
This function is only applicable when W630 work at TCP Client.
The registration USR-CLOUD function is that when W630 connects to the server, it sends the registration package
composed of device ID and communication password. The registration package information is correct, the server
returns the registration success information, and the W630 accesses the USR-CLOUD platform.
The registration USR (user-defined registration package) feature allows users to customize the content of the
registration package, and the length is limited to less than 40 characters (UDP Client supported, adding user-defined
registration packages before sent the data).
There are two ways to register the MAC / USR function: one is to send the registration information when connecting
to the server for the first time, and the other is to add the registration information to the data sent each time.
There is only one way to register a CLOUD, that is, to send a registry package to join USR-Cloud when connecting to a
server.

4.7. Class RFC2217 Automatic Baud Rate Function
RFC2217 is a standard protocol for instantly modifying device serial port parameters through Ethernet. This device
supports a protocol similar to RFC2217, not standard RFC2217, which implements the same function, but the protocol
is simpler.
