2 SAFETY GUIDELINES
Please read the following safety guidelines carefully! In case of property or personal
damage by not paying attention to this manual and/or by incorrect handling, we do not
assume liability. In such cases any warranty claim expires.
•The power supply must provide a stable 5 VDC output voltage. The output power
should be at least 2.5 W.
•Please pay attention that the power cord or other cables are not squeezed or damaged in
any way when you set up the Teleservice Gateway.
•The installation of the Teleservice Gateway should be done only by qualified personnel.
•Discharge yourself electrostatic before you work with the Teleservice Gateway, e.g. by
touching a heater of metal, to avoid damages.
•Stay grounded while working with the Teleservice Gateway to avoid damage through
electrostatic discharge.
•The case of the Teleservice Gateway should be opened only by qualified personnel.

3 HARD- AND SOFTWARE REQUIREMENTS
To work with the Teleservice Gateway MGW/865 a software development environment is
needed.
This development environment requires a computer as development system to access the
Teleservice Gateway via serial console or Telnet. Therefore usually a PC with Intel Pentium
or AMD processor under Windows or Linux is used. This PC should comply with the fol-
lowing hard- and software requirements:
•Windows 2000/XP/7 or Linux
•Serial (COM) interface
•Terminal program (HyperTerminal or Minicom)
•10/100 Mbps Ethernet network controller and TCP/IP configuration
•Web browser
•Telnet client
•CD-ROM drive
Please check which IP address your PC actual has. Keep this address in mind.
On a Linux-PC just open a shell console and enter ifconfig. On a Windows-PC please
open a DOS window (you can find it in the Windows Start menu) and enter: ipconfig.
Now the IP address is displayed in the DOS window.
Note: With a Linux-PC as development system it is possible to develop programs in
all languages for the MGW/865. Linux is especially for programming in C/C++ as
PC operating system required because of the GNU cross tools. With a Windows-PC
the shell-script programming as well as the HTML- and Java-applet programming of
the webserver is possible.

4 CONNECTIONS
For a quick and easy start with the Teleservice Gateway MGW/865 there are several connec-
tions necessary. The following chapters describe how these connections between the devel-
opment system (host PC) and the MGW/865 have to be made.
4.1 RS232 Serial Link
For a basic communication with the MGW/865 use the RS232 adapter cable and the null
modem cable on port COM1 of the MGW/865. These cables come along with your
MGW/865. Please connect the MGW/865 with the COM port of your host PC by using these
cables.

4.2 Ethernet Link
The Ethernet link can be made on two ways: with an Ethernet cross-over cable or with two
standard Ethernet patch cables and a hub or switch. In both cases an Ethernet LAN interface
for your host PC is required. When using a hub or switch please connect it between the host
PC and the MGW/865 like shown fig. 3.
Figure 2: Ethernet link with cross-over cable
Figure 3: Ethernet link with hub or switch
Note: For the Ethernet connection in fig. 2 it is absolutely required to use a
cross-over cable. Do not use an ordinary patch cable. Ethernet patch and cross-over
cables are in most cases visual indistinguishable. But the internal wiring is fully dif-
ferent. Mixing up these types of cables leads to LAN errors. Hence pay attention to
the label of the cable or packing.

4.3 Power Supply
To provide the MGW/865 with the necessary power you need a DIN-rail power supply with
an output voltage of 5 VDC.
Connect the plus-pole and the minus-pole of the power supply with the corresponding screw
terminals of the MGW/865. Please pay attention to the correct polarity!
Figure 4: Connecting the power supply
CAUTION: Providing the Teleservice Gateway MGW/865 with a voltage higher than the
regular 5 VDC ±10 % could resolve in damaged board components!
Please pay attention to the polarity of the power connector: the + pole is in the center!

5 OPERATION
5.1 Serial Connection
To make communication possible between the MGW/865 and the development system a ter-
minal program is needed.
Under Windows it is normally HyperTerminal, for Linux exists Minicom, an equivalent pro-
gram. In the following we use HyperTerminal, but all settings can be made similarly with
other terminal programs. If there is no terminal program installed on your development sys-
tem (this could be the case for a Linux-based PC), you have to install it manually from your
operating systems installation CD-ROM.
First open a new HyperTerminal session and enter a name for it (e.g. MGW/865). Choose
now under „File->Properties“ under „Connect via“ the entry „direct link cable connection
via COM1“ (or the COM-port you used). In the next step click on the button „configure“ to
get to the next dialog box.

Now change the settings to the parameters shown in fig. 7 and close the dialog box with a
click on „OK“.
Figure 7: Communication parameter settings
These settings can also be made in other terminal programs. Important are the following pa-
rameters and values:
Parameter Wert
Connection speed 115.200 bps
Data bits 8
Parity None
Stop bits 1
Protocol No (Xon/Xoff, RTS/CTS or similar)
Table 2: Terminal program settings
Note: Do not forget to save the session settings with the connection parameters under
the name you have chosen (e.g. MGW/865). With this name you can start the terminal
program for future MGW/865-access.
