We just need to follow the parameters of the corresponding set of network communication parameters, you
can make serial < -- > WIFI or Ethernet communication, the steps are as follows:
1. Open test software USR-TCP232-Test ;
2. COM Settings area (left):
C hoose COM port witch has connect the Convert Server , there is COM3, choose band rate to 57600 , this is
the default band rate of Convert Server , Click Open COM port.
3. Net Settings area (right):
C hoose TCP client mode, Server IP write 10.10.100.254, it is the WIFI default IP address, Server port to 8899,
It is the default Port the Convert Server listen, Click Connect to link to the Convert Server .
Now, you can test send data between RS232 and WIFI.
COM port to WIFI: PC RS232 -> Convert Server RS232 -> Convert Server WIFI -> PC WIFI .
WIFI to COM port: PC WIFI or Ethernet -> Convert Server WIFI or Ethernet -> Convert Server RS232 -> PC

So the device logically supports two wireless interfaces, one as STA,
another interface is equivalent to a
AP,
other STAs can connect to wireless network via the Convert Server AP
interface.

Convert Server support serial interface transparent transmission mode. The benefit of this mode is achieves
a plug and play serial data port, and reduces user complexity furthest. In this mode, user should only
configure the necessary parameters. After power on, Convert Server can automatically connect to the default
wireless network and server.
As in this mode, the Convert Server 's serial port always work in the transparent transmission mode, so users
only need to think of it as a virtual serial cable, and send and receive data as using a simple serial. In other
words, the serial cable of users
’
original serial devices is directly replaced with the Convert Server ; user

Convert Server supports the feature of binding the BSSID address of target network.
According to the provisions of 802.11 protocol, different wireless networks can have a same network name
(i.e. SSID / ESSID), but must correspond to a unique BSSID address (i.e. MAC address). Illegal intruders can
create a wireless network with the same SSID / ESSID, it will make STAs in the network to join to the illegal
AP,
thereby and then network leakage happen.
Users can prevent
STA
from joining to illegal network by binding the BSSID address, to improve wireless
network security.

Convert Server support UART free-frame function. If user select open this function, Convert Server will check
the intervals between any two bytes when rec ei ving UART data. If this interval time exceeds defined value
(50ms default), Convert Server will think it as the end of one frame and transfer this free-frame to WiFi port, or
Convert Server will receive UART data until 4K bytes, then transfer 4KB frame to WiFi port.
Convert Server ’ s default interval time is 50ms. User can also set this interval to fast (10ms) through
AT
command. But user have to consider if user MCU can send UART data with 10ms interval ,or the UART data
may be divide as fragment.
Through AT command: AT+FUARTTE=fas t /normal, user can set the interval time: fast (10ms) and normal
(50ms). This command is factory default setting command and AT+RELD can ’ t change its value.

Each TCP client first data is the “ password +0x0d+0x0a ” (the password is Webpage authentication password).
The default password is “ admin ” , so the first piece of data should be "0x61 0x64 0x6D 0x69 0x6E 0x0D 0x0A"
( Hex ). If the password is correct, the Convert Server returns "OK", on the other hand, return to the "NO" and

TCP connection password authentication: when the Convert Server in the TCP server mode, password

Note: this verification is only in a Convert Server as a TCP server.After the opening, the TCP client connected

This page is used to set two Ethernet front-end ports of the Convert Server , two Ethernet front-end ports
can be open or closed.And so the second can be set to the WAN port to use, this Convert Server can be used
as a secondary router, making it easy for users to network.Specific Settings page is as follows:

serial data can be added to the back of the HTTP header;When the request is a GET, data can be added to
the back of the path in the HTTP header.The specific way of sending data can consult section 4.2.4.

WAN port. Convert Server ’ s WAN IP address and LAN IP address shall be setting different segment.
So, Convert Server 2# ’ s LAN IP address must change to other segment; (For this sample, we

The following address allocation method can avoid the IP address confliction for dynamic and static IP
address mixed application.
Convert Server dynamic IP address range from 100 to 200 for last IP address segment.
Such as default IP: 10.10.100.254. When Convert Server works as
AP,
the IP address Convert
Server can allocate to STA is from 10.10.100.100 to 10.10.100.200;
So, if user needs to set static IP for dedicated
STA
internal network, the available IP address range
can start from 10.10.100.1 to 10.10.100.99.

All Convert Server supports UDP search ,they will return to their respective
IP,
MAC, MID, detailed search
process is as follows:
1. PC via UDP broadcast (broadcast address: xx.xx.xx.255, Port: 48899) sent a password, the default
password is: "HF-A11ASSISTHREAD", the password can be used
AT
commands (AT + FASWD) set
up,it's Up to 100 bytes.

2. After the Convert Server receives a password, if the password is correct, to the address (Unicast, Port:
48899) sends local IP address and MAC address and name of the Convert Server .
(IP,
MAC, MID as
10.10.100.254,888 B5D0000E2, guxin).
S o you can get to the IP address of the Convert Server .
