3. Installing WiFi-Adapter
1. Configure Web Access
You can access the WiFi-Adapter by using either an access point
with the SSID - Connect (with all encryption disabled, such as WEP
& WPA) or a wireless card with Ad-Hoc mode (with SSID Connect).
2. Installing the WiFi-Adapter Hardware
Connect your PC to the wireless network.
Connect the power to the DC jack OR the terminal blocks of
the WiFi-Adapter.
Connect your serial device to DB9 connector OR the 5-pin
terminal blocks.
3. Power up the WiFi Adapter
When the WiFi-Adapter is powered up, the Heartbeat LED will
be blinking and connect to the SSID Connect. If it cannot find
a SSID of connect it will connect to the first unsecured network
it found.
Find the wireless network icon on your computer (on Windows,
you'll find an icon that looks like 2 computers or a set of bars in
your taskbar on the bottom right of your screen; Macs will have
a wireless symbol in the top right).
View available WiFi networks by either right-clicking the icon
and selecting "View Available Wireless Networks" (Windows XP)
or clicking the icon and selecting to "Connect or disconnect..."
(Windows Vista). On Mac OS X and Windows 7, all you have to
do is click on the WiFi icon to see the list of available networks.
3
RS232 to WiFi Wireless Adapter w/ Mounting Kit
Choose the R2WiFi to connect to by clicking the "Connect"
button (or just selecting it on Win7/Mac).
Enter the security key -- if the wireless network is encrypted
(with WEP or WPA), you'll be prompted to enter the network
password or passphrase. This will be stored for you for next time,
so you'll only have to enter it once.
Start browsing the WiFi-Adapter!
You should now be connected
to the WiFi-Adapter; open your browser and visit the WiFi
Adapter at 192.168.2.3 default IP address. Login using admin for
both Username and Password.

5. Configuring the WiFi-Adapter to Access Point
If you are using this WiFi-Adapter with an access point, we
recommend you use the WiFi Wizard to guide you configure the
WiFi settings. Click WiFi Wizard button, choose Infrastructure
Network Mode, follow the Wizard’s instructions to complete the
installation.
4. Examples for Using the WiFi Serial Port
This section introduces an example to communicate with the serial port
of this WiFi-Adapter. We are using a Terminal Emulation Program (such
as HyperTerm or TeraTerm) to send data over the TCP/IP socket port
and receive the loopback data from the same socket port.
Similar to the HyperTerm example, the application software can read
or write data on the TCP/IP socket port through Windows API.
1. Launch the HyperTerm utility, it will create a new connection,
please type the connection name (type “TEST” in this case).
10
RS232 to WiFi Wireless Adapter w/ Mounting Kit
2. Enter the WiFi-Adapter’s IP address and port number:
3. Once the connection is built up successfully, the HyperTerm is
ready to send or receive data, add a loopback connector on the
DB9 connector or short the TXD and RXD pins on the 5-pin Terminal
Blocks. Type “Hello!”, if the screen shows the same characters
typed, then serial port is working well!

. Using Virtual COM Port Drivers
This WiFi-Adapter can work in ether Straight IP mode or Virtual COM
Port mode. The Straight IP mode will be accessed through its TCP/IP
socket port directly. The Virtual COM Port mode emulates a COM port
by installing the CentosSEC Virtual COM Port driver.
The Virtual COM Port software, CentosSEC, is an advanced software to
map your serial port devices (COM ports) to Ethernet so they could be
accessed from anywhere in the world (via Internet or LAN) as if it is
attached directly to the remote PC. When the attached serial port
device sends communication data it is actually transmitted over TCP/IP
network and back from the network to your device.
After installed, the driver allows Windows platform software, using
standard API calls, to be used in an Ethernet application.
Installing CentosSEC
1. Run the Centos_Setup.exe (right click “Centossec_Setup.exe” and
choose “Run as an Administrator”) on the supplied CD, it was
shipped in the following folder:
2. While installing the driver, please enter the password centos1104:
12
RS232 to WiFi Wireless Adapter w/ Mounting Kit
3. Follow the on-screen instructions to complete the Installation, you
are ready to launch the software utility.
Launch CentosSEC
After installed the CentosSEC, you will need to navigate either to the
Start Menu and locate the launcher in Programs submenu or
double-click the shortcut created on the desktop. Please note that
CentosSEC should be run as an administrator, for some Windows such
as 2008, Vista and 7, their UAC (User Account Control) will limit the
CentosSEC from working properly if you have only standard user
privileges. In this case, please right-click the CentosSEC shortcut on the
desktop, choose “Properties”, click “Compatibility” tab, enable the
“Run this program as an administrator” option of the privilege level
then click OK. Please see the following screen shot:

Configuring CentosSEC
1. Running the CentoSEC, the following screen will appear, click the
Help button will list the supported operations and details. You may
need to click Add to create a new COM port then click Update
All to save the settings. You don’t need to reboot the system after
you pressing Update All button for any setting update.
2. To add a new COM port, it is important to set the Net. Protocol to
RAW instead of TELNET for this WiFi-Adapter. After clicked Update
All button, the status field should become “Available”. If it is
“Registered”, it is not working properly. You need to review the
problem. Usually it because you did not run as an Administrator.

3. You may use “Load list” button to get the preset configuration file
(WiFi_RAW.dat) for the quick installation.
6. Operation Modes
The WiFi-Adapter can function as a server or Client for TCP and UDP
connections. The application scenarios include TCP Server mode, TCP
Client mode, UDP mode and TCP Server/Client Paired mode (using 2
WiFi-Adapters with one in TCP Server mode and the other one in TCP
Client mode). When in TCP Server/Client Paired mode, the 2
WiFi-Adapters are remotely connected without any need for extra
software or drivers.
16
RS232 to WiFi Wireless Adapter w/ Mounting Kit
1. TCP Server mode:
TCP Server mode provides the service at the TCP/IP socket port (factory
default is set at 192.168.2.3 port 5000). The application software works
as a client to this WiFi-Adapter. It can communicate via straight IP
address directly or via a Virtual COM Port driver.

2. TCP Server/Client Paired mode:
The TCP Server/Client Paired mode is designed for 2 WiFi-Adapters to
be connected in back-to-back via WiFi wireless network. The TCP
Server unit provides a service at 192.168.2.3 port 5000, the TCP Client
unit should set its Destination IP to match the Server’s service port
(192.168.2.3 port 5000). In this mode, the serial ports of the Server and
Client are remotely connected without any software support. It’s very
simple and straightforward.
