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.

4.1 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.

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.
