Getting started with the TS-2x00 for DOS

Connecting serial communications and power
==========================================

An ANSI terminal or PC running a terminal emulator is required to communicate
with your Embedded PC. The serial parameters are 9600 baud, 8 data, and no
parity. If you are running Linux, the minicom program works well, Windows users
can run the Hyperterm application.

Connect the DB9 ribbon cable to the COM2 header on the EPC. The 10 pin female
connector should be oriented so that the red lead on the ribbon cable is toward
pin 1 (pin 1 is closest to the "COM2" label and has a square pad) . 

Then connect the DB9 male connector to a null modem cable. Connect the other
end of the null modem cable to a serial port on the host. Technologic Systems
offers a null modem cable with both 25 pin and 9 pin connectors at each end as
part number CB7-06.

Connect a regulated 5VDC, (750mA minimum) power source using the included
2 screw terminal strip/connector. Please note the polarity printed on the board. 

Startup sequence
================

Apply 5VDC power. The board mounted LED will blink twice, followed immediately
by the display of the standard PC POST messages, memory test, and
configuration data on your terminal.  (Assumes JP2 is installed). 

After the power on self test the system boots DOS from ROM and executes the
'autoexec.bat' file. 

The ethernet packet driver is loaded.

The 'epc-test' program runs, this is used for functional testing prior to
shipment. See floppy for source.

The autoexec runs 'command.com' and displays the 'A:\' prompt. At this point
the system is still running the 'autoexec.bat' file, the call to 'command.com'
is just a shell. Type exit to leave the command shell so the 'autoexec.bat'
file will terminate. Now you may edit the autoexec file using 'ed.exe'.

DOS utilities	All source code for the utilities and Ethernet programs is
============	available on the floppy disk you received, or on the
                Technologic Systems web site (www.embeddedx86.com)

command.com     Run this from the command prompt for a more DOS like
                environment, type 'exit' to leave.

A:\Util \
=========

console.exe     Allows control of console redirection (screen and keyboard)
                baud rate and COM port.
dsz.exe		Z modem transfer program, see documents in util.zip on floppy.
dl.bat		Batch file for Z modem download from host computer using COM2.
ul.bat		Batch file for Z modem upload to host computer using COM2.
ed.exe		Simple line editor, see the document 'A:\util\doc\ed.man'.
epc-test.exe	Comprehensive test program, some tests require special hardware.
epclcd.exe      LCD port test program.
flashup.exe     Flash drive utility to create/restore complete flash disk
                images, see A:\util\flashup.txt
int.com		Software interrupt utility, see A:\util\int.doc for details.
int3.com        Calls BIOS debugger, type '?' at the debugger prompt for help.
led_off.com     Turns off board mounted LED.
led_red.com     Turns on board mounted LED.
reset.com       Turns on the CPU's watchdog timer, which causes a hard reset.

A:\Ethernet\
============

Epktisa.com     DOS packet driver TSR, uses A:\ethernet\wattcp.cfg to configure
                TCP/IP settings.
Httpd.exe       Web server daemon, see A:\ethernet\www\ for examples, read
                a:\ethernet\docs\minweb.doc
Comd.exe        Serial port to telnet redirector, download 'wattcp.zip' for
                source and documents.
Htget.exe       Hypertext file download utility, download 'wattcp.zip' for
                source and documents.
ping.exe        Standard ping utility to debug ethernet connection, uses
                wattcp.cfg file for configuration.

TCP/IP configuration
====================

The TCP/IP settings for the 2x00 are configured in the file
'A:\ethernet\wattcp.cfg', here is a  partial listing :

my_ip=192.168.0.20		// Internet Protocol address of this interface.
hostname="epc.t-systems.com"	// Host name of this computer.
netmask=255.255.255.0		// Used to determine which IP's are local.
gateway=192.168.0.1		// Gateway for internet access.
nameserver=192.168.0.1		// Name server for domain name lookups.

Notes
=====

To free up disk space on the A: drive you can delete the entire A:\DOS
directory. The DOS directory is not required to run DOS on the single board
computer,  ROM-DOS is loaded from a read only portion of flash and is therefore
non-volatile. You should retain the 'command.com' program in the root directory
if possible, as this makes the command interface much more usable. The DOS
directory is available on the floppy disk as 'DOS.zip' if you need to restore
any of the DOS programs. You can also delete any of the files in the A:\util or
A:\ethernet directories that you don't require. Make sure to delete any 
references to these files from 'autoexec.bat' file so the system doesn't hang.

Web server
==========

To access the web server, run 'httpd.exe' on the embedded computer. Open a web
browser on your network connected host computer and enter "192.168.0.20" as the
address. This should display the mini-server home page with some demo functions
displayed.

Telnet redirector
=================

Run 'comd.exe' on the embedded computer. Open a telnet client on your network
connected host computer and connect to 192.168.0.20. Connect a serial terminal
to COM1 on the embedded computer. Any characters received into the COM port are
redirected to the telnet client, any characters typed in the telnet client are
sent out the COM port.
