connection
USB connection is supported on Windows XP, Windows 7 and Red Hat Linux platforms. The
ST Micro Connect 2 uses TCP/IP to communicate over a USB connection.
For USB connection, the ST Micro Connect 2 acts as a DHCP server and issues an IP
address to the PC for the USB interface, thus creating a subnet. The address issued to the
PC is based on the ST Micro Connect 2 USB interface IP address. The default IP address
(see
Section 3.1
) can be modified as described in
Section 3.2
.
3.1
Default USB IP address
Warning:
The ST Micro Connect 2 has a default USB IP address of
192.168.2.1. This address may conflict with other network
devices already configured on your network which could lead
to network problems.
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.
3.2
Configure ST Micro Connect 2 USB IP address
If the default USB IP address of the ST Micro Connect 2 is used by other equipment, follow
these instructions to change the address:
1.
Before connecting your ST Micro Connect 2 to the host power it up, see
Section 1.3 on
page 11
for further details.
2.
To change the USB IP address, navigate to the LCD menu option
Set USB IP
and set a
new network IP address. Guidelines for choosing a new IP address can be found in
Appendix D on page 44
. LCD navigation is described in
Chapter 2 on page 13
.
If you wish to connect more than one ST Micro Connect 2 to the same host using USB, then
each ST Micro Connect 2 must have a separate
subnet
. The simplest way to achieve this is
to increment the third octet in the IP address. For example, if three ST Micro Connect 2s (A,
B and C) are to be connected to the same host, they could be given the IP addresses:
192.168.2.1
ST Micro Connect 2 A
192.168.3.1
ST Micro Connect 2 B
192.168.4.1
ST Micro Connect 2 C
