9 The 10 Base-T Ethernet Port
The TS-5300 has full-function IEEE 802.3 Ethernet capability (10 Mbit/sec) provided by a Cirrus Logic
CS8900A Ethernet controller. The CS8900A is a single-chip, 16-bit Ethernet controller that includes
such features as full-duplex operation, power saving shutdown modes, and LED indicators for link
status and activity. The physical interface is 10Base-T (RJ45 connector).
The TS-5300 has both a LINK LED and a LAN LED built into the RJ-45 connector that indicates the
current ethernet status. The LINK LED (right side of connector) is active when valid ethernet link pulses
are detected. This LED should be ON whenever the TS-5300 is powered on and properly connected to
a 10BaseT Ethernet network. The LAN LED (left side of connector) should pulse ON briefly when any
network traffic is detected. This includes all traffic, not just that sent to or from the TS-5300. Both of
these LEDs are controlled by the CS8900A and do not require initialization. Additionally, the LEDs can
be placed under software control, allowing the customer application use of the LEDs for feedback.
Please see the CS8900A User Manual, Appendix G , for further details.
The hardware settings for the CS8900A are stored in a non-volatile EEPROM chip, programmed before
shipment. The settings are – interrupt IRQ12, I/O address range 300h – 30Fh, and I/O mapped
operation. The hardware MAC address is also stored in this chip.
DOS TCP/IP configuration
A standard packet driver for DOS is installed on the board as shipped, along with sample network
applications written with the public domain Waterloo TCP/IP software (WATTCP). WATTCP is a freely
available package (including source code) that provides TCP/IP connectivity for programs written for the
DOS environment. See the Technologic Systems download page
ftp://ftp.embeddedarm.com/old/downloads/wat2001t.zip
In addition, we have written a simple DOS HTTP web server using WATTCP that is included on the TS-
5300 utility disk. The simple web server uses CGI calls to control a DIO pin from a web browser. Full
source code is included, and you are free to modify and extend the code for your own use on
Technologic Systems Single Board Computers.
The DOS packet driver (EPKTISA.COM) is loaded by
AUTOEXEC.BAT
once DOS starts, hardware
settings are read from the EEPROM chip and used by the packet driver to initialize the CS8900.
The TCP/IP settings for the WATTCP code are stored in the WATTCP.CFG configuration file in the
A:\ETHERNET directory, this file must be modified for the network environment where the TS-5300 will
be installed.
