    Product profile:
    Power input: Mini USB cable (5VDC) or DB9 connector Pin 9 (5VDC)or external power supply (4.8~24VDC,1.0 AMax.), please choose 1 source.

    DCE/DTE switch: DCE side. The switch will swap TX,RX,CTS,RTS of the COM port. Generally, DCE side for PC or NB setup. The user will test and switch to the correct side for the remote device.

    • DB9 Pin9 Power Input or Output:


    • External Power input or DB9 Pin 9 Power input: The two DIP switches toward N/Aside by default. Please do not switch any DIP switch toward the 5V side when the power switch is in the “External/Pin9 In” side.



    Remark: The power cable is used for the external power input which support larger range of voltage,4.5~24VDC.


    • DB9 Pin 9 Power output:


    The DB9 Pin 9 will power the external device by 5VDC via DB9 Pin 9 when the power input comes from USB only. Please choose the USB adapter which will power larger than1000mAh and do not power the external device which will consume exceed 100 mAh.



    • The RS-232 temperature/humidity sensor, active RFID reader or other sensors will be powered by the DB9 pin9 directly without extra power supply. If you need the options, please contact the suppliers.
