Please check that your rfid device is RS232 before connecting it to anything
Which rfid device is it ?.

Can you give a link to the C8051F350 board you are using ?.

the RFID I using is probably this :


That device is TTL output (5volts).. so don't connect it to anything until
I/we have had a chance to think about it

the link for micro controller is this, it contain the data sheet of my micro controller :


What you have is a chip ( a C8051F350) soldered to a board with other chips
connectors etc.
The chips are all the same, but different makers make different boards.

Is this the board you have ?

It might if you connect it to the +12 and -12 volts of an
RS232 connection.

Connecting the output of the rfid to an RS232 input would not cause harm, but
would not work properly either.

its TTL compatible dont even think of connecting it to 12V interface..

Very sad now, Left 4 weeks to finish this project... Guys u think 4 weeks can finish this project?

Four weeks should be enough.

You'll have to insert a ttl to rs232 level converter,preferably based on MAX232,between the RFID reader and the expansion cable.

Look here : http://www.8051projects.net/serial-communication/introduction.php

Ofcourse you can easily finish it out :-) we all here to help u out & u should try ur best.

check out this link for low cost RFID from Digant which is having UART and Wiegand o/p and works perfectly for micro-controller based application.

Hey, I think your site might be having browser compatibility issues. When I look at your website in Ie, it looks fine but when opening in Internet Explorer, it has some overlapping. I just wanted to give you a quick heads up! Other then that, very good blog! https://onanadiete.ru/alpha-numeric-reasoning-questions-and-answers-pdf.pdf alpha numeric reasoning questions and answers pdf alpha numeric reasoning questions and answers pdf
