Example:Send 00000107 which is read by an RFID reader from a tag and then from RS 232 , it is displayed on the computer screen(TELNET ) . Now this displayed data has to be transmistted to a computer in a Building..... http://www.8051projects.net/forum-t10461.html 2008-12-01T23:04:03-08:00 Ajay is "00000107" this decimal hex or a string?to transfer.. you can use the ezserver software which i used for home automation project. http://www.8051projects.net/forum-t10461.html 2008-12-01T23:04:03-08:00 Mushahid It is a patient data ID..which can be any number.....It is a string....Which is displayed on TELNET on a PC and it has to be sent to the hospital PC , so that the hospital is ready with the patient information when the patient arrives ,thus saving crucial seconds.. http://www.8051projects.net/forum-t10461.html 2008-12-01T23:04:03-08:00 Mushahid THE RFID reader reads the code fro the tag and sends to the computer via RS 232. The computer displays the read data on the TELNET screen. This data read should be sent to another computer in the hospital some miles away. I was thinking about using C++ to write a code for TCP commmunication and which reads the data and sends to the computer at hospital using wireless.... I am not too good at programming ...that is an issue with me.... http://www.8051projects.net/forum-t10461.html 2008-12-01T23:04:03-08:00 Ajay I am not able to get your properly..you are getting data from RFID reader then it goes to a PC via RS232 or telnet?if rs232 then its easy to transmit if telnet then you need to make a telnet forwarding client kind of software (using VB or something).can you tell me how the string is being terminated? if sent via rs232. Termination means the last character any \r or \n is available or not? http://www.8051projects.net/forum-t10461.html 2008-12-01T23:04:03-08:00 Ajay just do a small testing..connect the reader to com port of PC, open haserver or ezserver (download from website) now try connecting from other computer to server PC via telnet. See if you are getting the string on your remote telnet window or not. http://www.8051projects.net/forum-t10461.html 2008-12-01T23:04:03-08:00 Mushahid I will try it now....Thanks http://www.8051projects.net/forum-t10461.html 2008-12-01T23:04:03-08:00 Mushahid I am not getting it..I have downloaded ezserver....2.0 ver.....and opened hyperterminal on the other computer.....and no display of string...The string is displayed on my PC where the RS 232 is connected to the Reader...so how do I connect the server PC via Hyper terminal. http://www.8051projects.net/forum-t10461.html 2008-12-01T23:04:03-08:00 shyam well first of all...how far can the remote PC be from your laptop?? http://www.8051projects.net/forum-t10461.html 2008-12-01T23:04:03-08:00 Mushahid The PC is located miles away. let us assume it to be 10 km away. And the ambulance has to transfer the patient code to the hospital before it gets there, lest it should serve the purpose.
