4 Ethernet
connection
Ethernet connection is supported on Windows XP, Windows 7 and Red Hat Linux platforms.
If your Ethernet LAN uses a DHCP server to configure the network, then before your
ST Micro Connect 2 is physically connected, it must have DHCP capability enabled by using
the LCD configuration menu as described in
Section 2.2 on page 14
. The ST Micro
Connect 2 can then be dynamically configured for Ethernet connection using DHCP.
Alternatively your ST Micro Connect 2 may connected to an Ethernet LAN and be
configured with a static address for that network.
4.1
Default Ethernet IP address
Warning:
The ST Micro Connect 2 has a default Ethernet address of
192.168.1.1. This address may conflict with other network
devices already configured on your network which could lead
to network problems.
The use of the default IP address is
not
recommended for Ethernet installation.
When there is the possibility of a network conflict then the ST Micro Connect 2’s IP address
should be changed using the LCD interface as described in
Section 4.2
or
Section 4.3
as
required. For static configuration this should be done before the ST Micro Connect 2 is
physically connected to your host or network. When DHCP configuration is enabled, the
ST Micro Connect 2 will automatically attempt to find a new address when it is connected to
the network, as described in
Section 4.2
.
Appendix D: Choosing an IP address on page 44
provides more detailed guidance about
the possible source of network conflicts and how to avoid them. If in doubt ask your network
administrator.
Note:
The ST Micro Connect 2 firmware, version 3.4 onwards, supports
Classless Inter-Domain
Routing
. Earlier releases of the firmware supported
classful
IP addressing and the
documentation assumed private
class C
addresses in the range 192.168.0.0 to
192.168.255.255. Since version 3.4 you can set any network mask on both the Ethernet and
USB interfaces.
Consult your network administrator for details of local IP addressing policy and network
mask values.
Should it be required to use the default ST Micro Connect 2 Ethernet IP address (and you
are certain a network conflict will not occur) then it is possible to do so and this method is
described in
Appendix E on page 48
