  2. pairing the devices

  3. plug DC power , the device will auto connect,
    (if the devices has been paired )


Configure Baud Rate :

  1. Setting The serial port software to the expected BAUD rate and 8 bit data , no parity ,one stop bit. (example windows Hyper Terminal ).

  2. Hold down the “key “ and then plug DC power. The Green LED flash indicate which baud rate is setting

Flash 1 time

Flash 2 times

Flash 3 times

Flash 4 times

Flash 5 times

Flash 6 times

4800 bps

9600 bps





  1. release the “key”

  2. toggle the “key” until the software received the correct baud rate character.(example : baud rate 115.2k ),Press the key one time the baud
    rate will increase and the Green led flash also increase. The baud rate increase form 9600->19200->38400->57600->115200->9600,cyclically.

  3. send any data form PC will echo back by bluetooth device.

  4. If it echo correct .indicate that configure baud rate finished

  5. remove DC power ,the configuration process is finished

  2. press the “key “ on both device

  3. wait 1-2 minute (for it auto pairing and communicate).

  4. if communicate finished the RED LED will indicator .
