2 Description
STE02W is a device that allows the transfer of a serial port through a wireless network or,
more generally, through an Internet connection.
It has a RS-232 serial port on DB9 connector that can be connected to different types of
serial devices (e.g. PLCs, controllers, keypad security, access control devices, etc.) and it
can send e-mail messages when an alarm condition occurs.
You can also interact remotely, connecting via Internet to the STE02W with a browser, to
check the status and information of your serial device.
To meet different needs, you can set the speed of serial interface, the parity bits, and stop,
the format of the data and the type of flow control; this way you can adapt STE02W to your
application quickly and easily.
STE02W is designed to work in different applications being able to handle, in addition to
connecting to a PC, even communication between two serial devices networked through
both STE02W. Main operating modes are: Real Port, Serial Bridge, TCP Socket, UDP
Socket, Modem Emulation.
Furthermore, it can be supplied with an extended range of voltages, through the
appropriate pin on terminal block.

4 Installation
4.1 Hardware Connection
4.1.1 Connecting to the Wireless network
Turn on the device and wait for the Link LED to stop blinking; this means that STE02W is
connected to one of the available wireless networks. The converter is able to connect to
networks with access point or ad-hoc networks. If the Link LED does not stop blinking,
make sure that the device is in an area covered by Wireless Lan or that the network
security features are compatible with the security settings of your STE02W.

4.1.2 Connecting a serial device
Connect DB9 male connector of STE02W to serial device using RS-232 serial cable (DB9
M/F); if STE02W needs to be connected to a PC or another device with serial port DTE
use a NULL modem cable (DB9 F/F).

4.1.3 Connection to Power Line
Connect the included power supply to power connector placed on back of device. Then
connect the power supply to power line.

4.2 Configuration Software
4.2.1 Software Installation
To configure the device easily you can use the installation wizard. This procedure allows
you to install and run ' MG Device Wiz’ for STE02W devices configuration. ‘Mg Device Wiz’
allows you to automatically detect the device in the network which has been linked and
initialize the main parameters for its proper functioning as well, and access to the WEB
interface. Also optionally installs a third-part drivers needed to work in Real Port mode.
Using this driver a virtual COM port is redirect on ethernet port and physically remoted to
STE02W serial port. The Java Virtual Machine required to view the configuration interface
via browser is included in this installation procedure and is still available on the provided
CD.
Figure 9: Installation procedure: Welcome Page.

12
To install the application, simply launch the setup.exe file on CD included and follow the
installation wizard. Done this procedure you can boot MG Device Wiz from
Start/Programs/STE02W Management folder or from the directory where you chose to
install the program. The installation procedure will create a new folder, STE02W, and MG
Device Wiz will be installed.
You can also automatically install Java Virtual Machine required for viewing browser
interface and Real Port driver provided in support.
Figure 10: Setup: Setup completed.

4.2.2 Configuring device with ‘MG Device Wiz’
Figure 11: MG Device Wiz: Welcome Page.
Verify that you have followed the steps and press ‘Next’, or press ‘Cancel’ to exit the
wizard.

14
Figure 12: MG Device Wiz: Devices List.
Figure 12 shows the list of STE02W devices detected in the local network; you can update
this list by clicking on the ‘Refresh’ button. Select the device that you want to configure and
press ‘Next’ button, or press ‘Open WEB Interface’ to open the advanced configuration
page; in this case it is necessary that the device is in the same subnet of the computer.
If your device is not displayed in devices list, verify that:
−the device is correctly connected and powered
−no firewall blocks network access to MG Device Wiz
If you want to return to previous page, you can press ‘Back’ button, if you want to stop the
wizard and then exit the program press ‘Cancel’ button.

15
Figure 13: MG Device Wiz: configuring network parameters.
In the window shown in Figure 13, you can assign to the selected device a static IP
address, mask and gateway, or set up automatic selection of these parameters using
DHCP. After the selection of options, press ‘Next’. Also in this case you can press ‘Back’ to
return to the previous page or click ‘Cancel’ to exit procedure.

16
Figure 14: MG Device Wiz: Verification of values set.
The screenshot in Figure 14 shows the parameters entered on the previous page, press
‘Next’ to send configuration to device. Before proceeding, verify that values shown are
correct. After sending the configuration you can run a new configuration to change
parameters.

17
Figure 15: MG Device Wiz: Device configuration.
The window in Figure 15 show advancement in sending data to STE02W; during this
process, the device is first configured and subsequently restarted. Do not disconnect or
turn off the device during this phase.

18
Figure 16: MG Device Wiz: Procedure ended successfully.
The window show in Figure 16 appears at the end of the wizard, device has been
properly configured with the settings entered by the user. You can press ‘Cancel’ or
‘Finish’ to exit the configuration program. If the device is not visible after the wizard,
contact your network administrator and check if IP address and Subnet Mask are correct.

19
Figure 17: MG Device Wiz: Configuration error.
If while sending the configuration this screen (fig. 17) appears, it means that the
parameters previously entered are not correct. Re-run the configuration by entering
appropriate values in IP address and Subnet Mask.

20
4.3 Advanced Configuration
To run advanced configuration of the system you need to access WEB interface of device
that you want to set. This procedure can be started by entering in browser toolbar the
device's IP address, assigned previously, preceded by http:// (for example:
http://192.168.100.100). A screen will appear first to load the Java Applet and then a
dialog that required the insertion of user name and password, respectively ‘admin’ and
‘admin’. You must wait a few seconds before the configuration window appears. The Java
Virtual Machine required for procedure is available on the included CD and can be
downloaded also at http://java.sun.com or installed automatically during the installation of
the provided programs.
Figure 18: Loading java applet.
WARNING: do not close this window while running configuration procedure.
After loading, Java application displays the home page of configuration WEB interface,
which contains general information about the device and links to various parameters
settings.
