58 Wildcat (BL2000)

5.4 Running More Sample Programs With a Direct Connection

The program SSI.C (SAMPLES\BL2000\TCPIP\) demonstrates how to make the

BL2000 a Web server. This program allows you to turn the LEDs on an attached Demon-

stration Board from the Tool Kit on and off from a remote Web browser. LEDs DS4–DS8

on the BL2000 will match those on the Web page. As long as you have not modified the

TCPCONFIG 1 macro in the sample program, enter the following server address in your

Web browser to bring up the Web page served by the sample program.

http://10.10.6.100

Otherwise use the TCP/IP settings you entered in the TCP_CONFIG.LIB library.

The sample program SMTP.C (SAMPLES\BL2000\TCPIP\) allows you to send an E-mail

when a switch on the Demonstration Board is pressed. Follow the instructions included

with the sample program.

The sample program TELNET.C (SAMPLES\BL2000\TCPIP\) allows you to communi-

cate with the BL2000 using the Telnet protocol. This program takes anything that comes

in on a port and sends it out Serial Port B. It uses digital input IN0 to indicate that the

TCP/IP connection should be closed, and it uses high-current output OUT0 to indicate that

there is an open connection. You may change the digital input and output to suit your

application needs.

Run the Telnet program on your PC (Start > Run telnet 10.10.6.100). As long as

you have not modified the TCPCONFIG 1 macro in the sample program, the IP address is

10.10.6.100 as shown; otherwise use the TCP/IP settings you entered in the

TCP_CONFIG.LIB library. Each character you type will be printed in Dynamic C's STDIO

window, indicating that the board is receiving the characters typed via TCP/IP.

5.5 Where Do I Go From Here?

NOTE: If you purchased your BL2000 through a distributor or Rabbit partner, contact

the distributor or partner first for technical support.

If there are any problems at this point:

• Use the Dynamic C

Help menu to get further assistance with Dynamic C.

• Check the Rabbit Technical Bulletin Board and forums at www.rabbit.com/support/bb/

and at www.rabbit.com/forums/.

• Use the Technical Support e-mail form at www.rabbit.com/support/.

If the sample programs ran fine, you are now ready to go on.

Additional sample programs are described in the Dynamic C TCP/IP User’s Manual.

Refer to the Dynamic C TCP/IP User’s Manual to develop your own applications. An

Introduction to TCP/IP provides background information on TCP/IP, and is available on

the Web site.
