to download the data i have to send the request
response of this command will be
But when i send this command through Serial Port, I am getting same string as command.
Please suggest me the solution for this.
Do a search on this site for MODBUS, it may help explain. MODBUS is a specific protocol, and I'm not sure that just sending the string you refer to is sufficient. Also, make sure that you have the communications cables correctly connected, it sounds like you may be getting just an echo back, that the output serial pin may be connected to the input side.
