  • Tips ( very important ):
    TXD: the sender, usually expressed as its sender , the normal communication must be connected to another device RXD.
    RXD: the receive side, generally expressed as the receiving end of their normal communication to another device connected to TXD.
    When normal communication TXD never received their equipment RXD!
    Collected spontaneously : normal communication other devices connected RXD TXD, so if you want to receive data sent their name suggests, it is their own transmitted data received , which is connected directly to its own TXD RXD, used to send and receive the test itself is normal, is the quickest and easiest way to test if a problem occurs first do the test to determine whether a product failure. Also known as the loopback test.

    Level logic:
    TTL level: typically binary data representation , provides +5 V equivalent to the logic "1", 0V is equivalent to logic "0" , is called a TTL signal system is the positive logic
    RS232 level: the -12V to -3V, equivalent to logic "0", +3 V to +12 V logic level is equivalent to logic "1" , the negative logic.

    1 The main chip CP2102, generate a virtual serial port after installing the driver
    2 USB to take power, leads to the interface includes 3.3V(<40mA),5V, GND, TX, RX, the signal pin level is 3.3V, positive logic
    3 Onboard status indicator lights transceiver, install the correct drivers status indicator lit, when the communication transceiver indicator flashes , the higher the intensity , the lower the baud rate
    4 Support 300bps~1Mbps baud rate
    5 Support communication format: 1) 5,6,7,8 data bits ; 2) 1, 1.5, 2 stop bits ; 3) odd, even, mark, space, none verification.
    6 Support operating system: windows vista / xp / server 2003/200, Mac OS-X/OS-9, Linux
    7 Male USB head, can be directly connected to the computer USB port
    8 SMT chip components for the production process , quality and stability
