Testing

Hardware connection

  • Prepare the following things before using the module::
4G SIM card (China Mobile, China Unicom or Telecom card, without shutdown and GPRS enabled); 
Headset cable with microphone (optional); 
Micro SD card (optional);
micro USB cable
LTE antenna
  • Insert the SIM card and earphone to the A7600X board, if you want to test the TF card slot, you can also insert a TF card to the card slot.

800px

  • Connect the USB interface of A7600X board to PC.
  • The PWR indicator turns on after connecting
  • When the default jumper cap is set to 3V3<->PWR (as shown in the figure above), the module will automatically turn on when it is powered on.
    If it is set to PWR<->P22, you must manually press the PWR button to turn on: Press the PWR button for about 1 second, wait for about ten seconds to turn on;
    When the NET light starts to flash, the module starts to network normally.
  • Open the device manager and install the windows driver file Windows Driver,Refer to the figure below:
  • Check the Device Manager of PC, the several COM ports will be recognized::
