Chapter 11: Ethernet
Description
The XE–800 SBC provides a 10/100BaseT Ethernet port and supports the IEEE
802.3 Ethernet standard. The XE–800 SBC uses the Intel 82551ER Ethernet chip.
This chip is fully Plug-N-Play compatible.
The Ethernet controller IC chip provides the following:
8K x 16 SRAM buffer
Integrated 10/100 BaseT transceiver interface
Two LEDs for link and traffic status integrated into connector
The XE–800 SBC Ethernet uses twisted–pair wiring cable, which is built in a star
configuration. The interface terminates at the standard, 8–position, RJ–45
latching jack.
CAUTION
Use a strain relief loop when connecting to the XE–800 SBC Ethernet
connector to avoid damaging the connector.
The Ethernet port uses IRQ11.
For more information on programming the Ethernet port, see the README file in
the Ethernet directory of the Utility zip file (see page 113).
