3. POWER SUPPLY
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)
• Connect the USB to the USB port of PC or laptop.
After providing power to RFID-IDR-232N, the LED will light ON with the RED color and
buzzer will beep.

4. USING RFID-IDR-232N
The hardware connection must be setup before RFID-IDR-232N can be used.
Connect RJ11 cable connector into RFID Reader as shown in figure.
The communication line has to be connected to serial port of PC.

After both power and communication line are connected, the HyperTerminal (software)
need to be configured:
a. Open HyperTerminal
b. Choose COM1 (if you connect to COM1)
c. Configure the properties of COM1 to:
i) Baud rate (Bits per second) = 9600
ii) Data bits = 8
iii) Parity = None
iv) Stop bits = 1
v) Flow control = None
Now, RFID-IDR-232N is ready to read address of a 125 KHz passive tag. Move
the tag slowly towards RFID-IDR-232N (top), at approximately 2cm from the casing, the
buzzer will sound, LED will turn to green when the tag move slowly towards RFID-IDR-
232N and HyperTerminal will show the tag’s ID in ASCII.

Figure above show the protocol of the RFID Reader. The extra byte of data at the first and
the last of tag ID’s. If the protocol users have is different from the protocol above, please
contact us at [e-mail] immediately.

5. PIN CONFIGURATION
If RFID-IDR-232N is require on embedded system where no PC is available,
hardware modification and interface is necessary. USB will provide 5V and ground to
RFID-IDR-232N, while female DB9 is communication line to PC. Below show the
pin configuration of USB, RJ11 and DB9 of RFID-IDR-232.

6. RFID-IDR-232N Protocol
High level language which can access to serial port can be used to develop program for
RFID-IDR-232N on desktop PC or laptop. Some examples of high level language are Visual
Basic, Labview and Visual C++.
If RFID-IDR-232N is connected to microcontroller, Assembly language or C
compiler (depending on microcontroller type) can be used to write program.
RFID-IDR-232N will read the ID from RFID tag if the tag is near enough to RFID Reader. The
ID is normally 10 digit of number. RFID-IDR-232N will automatically send this ID with 1 byte
of Start of heading (0x01), followed by 10 byte of ASCII character (ID) and 1 byte of Start of
text (0x02).
The 1
st
byte will be read is “Start of heading” followed with 10 bytes of RFID Identification
number. The last 1 byte is “Start of Text”
