Good day guys! First off, I'm not really sure if this is the right section to post this problem , but since it is related to my project I guess it is somehow ok :D

Anyway, I recently bought this RFID reader

http://www.soselectronic.com/a_info/resource/c/ACM08Y_ID_Card_reader.pdf

I have experienced programming RFID reader like the RDM630 before so i thought I will have no problem in using this one..
I've tried reading the data sent by the RFID using an McU but all I get is random characters of øøøøøøÿÿÿÿÿÿÿÿ and I have no idea why. I haven't experience having problems like this on the RDM630 before. Baud rate is set at 9600

Anyone has any idea on how to solve this problem? Should I use a hyper terminal or the McU way of serial monitor is just fine?

Without seeing your code, do you really think we can explain why?

Looks like a baud rate mismatch or possibly that the data bits are inverted from not using a MAX232 on one side.
Experience, it's what you get when you were expecting something else.
