week 11

In this project,i use RFID reader RS232. i do not neeed to connect the reader with PIC since the reader has interphase inside it. so the reader can communicate with the PC just by using the USB converter. These ports are used for the transmission (TX) and reception (RX) of data. These transmissions possible with help of various digital data transceiver modules like RF, IR, Bluetooth, etc.

RFID-IDR-232N is plug and use RFID reader. It has been designed with capabilities and features
of:
• Low cost solution for reading passive RFID transponder tags.
• Industrial grade casing for better outlook and protection.
• Every reader has been tested before is being shipped.
• 9600 baud RS232 serial interface (output only) to PC.
• Fully operation with 5VDC power supply from USB port.
• Buzzer as sound indication of activity.
• Red and green color LED for visual indication of activity.
• Standard RS232 serial cable (female) ready to plug to desktop PC.
• USB as power source from desktop PC.
• 2cm reading range.
• 0.1s response time.
• 12 bytes of data received include start of heading, RFID ID and start of text.

RFID-IDR-232N is fully working RFID tags reader and can be applied in:
• Security system.
• Car parking.
• Office.
• Hypermarket for item pricing.
• Student projects



RFID-IDR-232N power source is from USB connection. There is no communication
through USB connector, only 5V is taken from this connector. The communication line is
RS232 cable (serial port with female DB9).
