    Tips: Preparations for using data transfer unit.

    1. Install antenna for data transfer unit, and then install power supply, and make sure that the DIP switch status is correct. Users select wire pressure method or power adapter to supply power according to needs, and either one can be selected.
    2. Use USB to RS232, USB to RS485 or other methods to connect computer to data transfer unit.
    3. Start two serial port debugging assistants. Select serial port baud rate of 9600bps and verification method of 8N can achieve serial port transparent transmission.
    4. If users need to modify specifications, please adjust data transfer unit to configuration mode and connect it to computer. Open configuration software to modify specifications. After completing configuration, be sure to restore DIP switch status, then communication can start.
