How to send data through ethernet

Hi all, I think S. is talking about DMX512 or something similar to it.



S. you need to do some research into DMX protocols, which is the
facto-standard for lighting control systems.



I think you can find it on a search in this forum or even on a google
search to find the .org in charge of the DMX format.



This forum is designed for educated users to help!



If you need someone to write most of your code, then please go to the
Rabbit Web site and go through the selection of a consultant to assist
you with your code development.





This forum is a great source of information and by careful searching,
most answers can be located within.

Hi,

Thanks for your response.I have gone through
TCP/IP documents and also code what you told .I executed and i able to
see the data on stdio what i typed in command prompt.But My question is
for my application i,e lighting controller which needs some segments of
LED to turn on and off  can i use telnet.Plz tell me how telnet which
is in application layer communicate to UDP and UDP to IP in network
layer.What changes needed to be done in code to make inter
communication between these protocols.

 

I think though i asking you basics plz tell me
how exactly to do in  the code.

Dear indian friend. First you must learn the basics

of TCP/IP to do what you want. What a socket is, what

a server is and what a client is. Google it and study

it for a while before try to do something.

For now, if you are so impatient, run the

samples/tcpip/telnet/rxsample.c in debug mode (Enable

RST28 instructions in the compiler options) and remove

this line from the top of this program:



#define INPUT_COOKED



Removing this line you´ll be able to see on the stdio

screen the same data you sent through telnet

connection.

Once rabbit is running this sample code with this

define removed, open your dos prompt and issue a

telnet command. An example for rabbit´s IP assumed

like 192.168.0.100 is:



telnet 192.168.0.100



The port 23 is default port for telnet service. Once

the connection is stablished (it will be prompted on

stdio screen) start typing some chars on dos prompt

and check if they are being printed on stdio screen.

So, voila, you are sending data from a PC to Rabbit

as you wish...

For specific aplications you must write a telnet

client software using, delphi, c++, mfc or even C for

the PC side.



Best regards
