Ethernet Interface 31

15.1 Connector

The Ethernet interface is available through Connector J7 (8 pins). To find the location of this

connector on the T-MOPSlcdSA board, please see the chapter “Connector Locations”.

To have the signals of the Ethernet connection available on a standard RJ45 connector, you need

an adapter cable. For adapter cable information see the section “Connector Functions and

Interface Cables”.

Pin-out table:

Header Pin Signal Name Function In/Out

1 TXD+ (*) 10BASE-T Transmit Differential Output

2 TXD- (*) 10BASE-T Transmit Differential Output

3 RXD+ (**) 10BASE-T Receive Differential Input

4 SHLDGND Shield Ground

5 SHLDGND Shield Ground

6 RXD- (**) 10BASE-T Receive Differential Input

7 SPEEDLED (***) Speed LED Output

8 LILED (***) Link LED Output

Notes:

(*) TXD+, TXD- differential-output pair drives 10- and 100-megabits-per second Manchester-

encoded data to 100/10BASE-T transmit lines.

(**) RXD+, RXD- differential-input pair receives 10- and 100-megabits per second Manchester-

encoded data from 100/10BASE-T receive lines.

(***) SPEEDLED and LILED have an onboard 470Ohm serial resistor and can directly be connected

to a LED’s cathode. Connect anode to VCC.

15.2 Configuration

You can download available drivers and setup utilities from the Kontron Web site. Please refer to

the corresponding readme and setup/install files. For further information contact your local

technical support.

You can enable/disable the Ethernet controller from the “Advanced Menu” in the BIOS setup utility

or enable the Onboard LAN PXE ROM to boot the system via Ethernet connection from a PXE server.

See the “Boot Menu” section in the “Appendix B: BIOS Operation” chapter for more information.

15.3 Ethernet Technical Support

If problems occur, you can solve some of them by using the latest drivers for the INTEL® 82551IT

controller. Kontron provides you with the latest in house- tested drivers, which can differ from

newer ones. For further technical support, contact either Kontron or get support information and

downloadable software updates from Intel®.
