USR-WIFI232- 610 module can be set as STA or AP. 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 module AP interface.

USR-WIFI232- 610 internal complete protocol conversion, customers does not need to care
about the details. The serial port side serial data transparent transmission, WIFI network side
is TCP/IP packet, specify the working details through simple settings. Can be set by module
built-in webpage, by serial port using AT command and by our software in CD.
4.1.1 Set up via Web pages
Keep WIFI network connection, login web page http://10.10.100.254, the user name and
password are both admin.
4 .1.2 Set up via COM port
Connect the module COM port to PC COM port, install the software runtime lib,
then run A11_Config_serial_en.exe , click Connect, after success, click
Read, then you can setup the settings.

4 .1.3 Setup via WIFI Software
Only firmware after than 3.29.xx has this function, You can find your firmware version in
the web pages, use WIFI network to setup the module, you still need to install the
gtk2-runtime.exe, Open WIFI network card and Forbidden RJ45 network card, setup PC IP
address to 10.10.100.123.
Run A11_Config_net_en.exe

RS232/RS485 to RJ45&WIFI converter http://en.usr.cn
Jinan USR IOT Technology Limited p age 14 of 22 [email protected]
Power off and on module, Wait the module start up, connect WIFI network card to the module
HF-A11x_AP network, after WIFI network ok, the module will auto connect to the setup
software, the led go to Green, Click Read, then you can configure the WIFI module settings.

4 .1.4 Hand AT Command
This method is similar with 2.2, it is by hand while the 2.2 do by software. This show the AT
commands work detail, if you would like to configure the module via you MCU, this is important
for you.
Connect your module COM Port to PC COM port.
First send three plus signs +++ , notice only three chars, no <CR> and no <LF>, you will
receive a char asend back from module, then in three seconds, send back a char aback to
the module, after that you will receive +ok to notice it has go in to AT command mode, send
AT+H and Enter (CR and LF ,0x0D + 0x0A) to get help, AT+ENTM and Enter for back to
transparent transmission mode. More detail AT commands description please see the data
sheet, the test step screen is here, (Only receive message, send chars can't be see)

USR-WIFI232- 610 support serial port transparent transmission mode, can realize RS232
serial plug and play, to minimize the complexity of using. In this mode, all data that need
transmit and receive are transparent transmission between serial interface and WIFI, don't
make any resolution.

In transparent transmission mode, can be completely compatible with users original software
platform. The user equipment do not need to have basic software change, to realize the
wireless data transmission.
<Reminding:>
Transparent transmission mode as a lower level data transmission, itself can not guarantee
zero error rate in data transmission. The users can adopt higher level TCP protocol handshake
or open the serial port hardware flow control function(RTS/CTS), this will reduce the error rate
to the lowest. If the users does not need serial port hardware flow control function, just put the
corresponding pin feet(CTS/RTS) vacant.

USR-WIFI232- 610 device provides a 100M Ethernet interface, through which customers can
realize WIFI port, Serial port and Ethernet port these three ports interworking. In building
network aspect, The USR-WIFI232- 610 support bridging mode and routing mode to deal with
different specific applications.
<Reminding:>
For different networking mode, USR-WIFI232- 610 require commands to switch version(as
description of N-Ver and Z-Ver below). Use command AT+FVER=n to switch to N-Ver,
AT+FVER=z to switch to Z-Ver . Default N-ver

For these embedded system equipments that without operating system or no USB port to
extend WIFI card, you can use the module Ethernet to WIFI transparent transmission function.
So with strong signal, this module can also work in the distance that general USB network card
can not competent. Even can make half cable network and half wireless for longer distance.
(Please reference to Ethernet to WIFI transparent transmission documents)

In the picture, USR-WIFI232- 610 use the AP+STA function, module STA interface can be
connected to router, and network server through TCP connection. At the same time, the
module AP interface is also available, cellphone/PAD ect can connect to AP interface(through
TCPB connection) to control serial equipment or set the module.
With AP+STA function, can easily use hand equipment such as cellphone or PAD to
monitor user equipment, without changing the original network settings.
With AP+STA function, can easily set the module, solving the problem of module can only
