I have a RFID Reader like the one posted on this link: http://www.ebay.com/itm/EPC-Gen2-UHF-Integrative-5-7-Meters-Long-Range-RFID-Reader-with-free-SDK-/171473207602
It has RS232, RS485 and Weigand interfaces. I tried interfacing it using a Prolific USB to Serial Converter and a RS232 to TTL logic level shifter with MAX3232 CSE in it but with no luck of getting a data.
How can I attach this reader to the Pi and how can I interface this? What are the recommended Python libraries that I could use? Thank you very much!
