3.4 Communication between PC and
IE-GPRS-I/O
The communication is realised via a serial connection. To display
the HTML user interface of the IE-GPRS-I/O, Microsoft Internet
Explorer, version 5.5 or higher is required. For the relevant
information required to configure the IE-GPRS-I/O via the serial
interface, please refer to Section 4.1.
To configure the IE-GPRS-I/O using the HTML user interface, it is
imperative to know the current Ethernet address of your IE-GPRS-I/O.
The factory setting is 192.168.1.120.
• In the Windows operating system, set up the IE-GPRS-I/O as a
long-distance data transmission connection ("Dial-Up Networking",
see Section 4.1.1 Setting up the virtual modem and the long-
distance data transmission connection under Windows XP).
• Configure a serial COM interface of your PC for the IE-GPRS-I/O
(see Section 4.1 Configuring the 218HIE-GPRS-I/O via the RS 232
interface).
• Establish the connection either by clicking on the previously created
shortcut on the desktop or use Start – Settings - Dial-Up
Networking - IE-GPRS-I/O
;
IE-GPRS-I/O stands for the name of the connection.
• In the Internet explorer, call the start page
http://192.168.1.120/index.htm.
• After a few seconds, the start page of the parameterisation user
interface is displayed.
The IE-GPRS-I/O is addressed directly via the long-distance data
transmission connection and cannot itself communicate with a network
connected to the PC. The IP address of the IE-GPRS-I/O is not visible
in the network of the PC. Thus, no attacks are possible against the
IE-GPRS-I/O from the network. Furthermore, no address conflicts result
with devices with the same network address in the network.
