    Interface description:

    GND: Power ground
    VCC_IN: Power supply pin, input DC5V-20V
    RI: Ring indicator
    DTR: Data terminal preparation
    TXD: TTL serial port transmission
    RXD: TTL serial port receive 
    U2_R: module serial port 2 receive
    U2_T: module serial port 2 send transmission
    V_M: connect to the core voltage (5V/3.3V,it depend on your MCU) of MCU for level match(generally, NC also be OK for this pin)
    ADC: ADC detection
    SPP: Audio output positive
    SPN: Audio output negative
    MC-: Audio input negative
    MC +: Audio input positive
    PWR: Power enable or disable(enable when low level)
    BAT: lithium battery input pin, 3.3v-4.4v

    Basically instructions:

    The SIM800C mainly controlled by AT commands, so just find a USB convert to TTL serial port module,and 5V,GND,TXD,RXD pins connect to VCC_IN, GND,RXD, TXD pins of SIM800C
    When the module is started, the indicator LED flashes once every 1 seconds, and after a period of time, the indicator LED flashes once every 3 seconds, it means the SIM800C start works normally.
