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:：

Raspberry Pi

实物连接

AT7600X Cat-1/GSM/GPRS Hat 板载树莓派GPIO接口，可直接插入各版本的树莓派使用
硬件连接图

File:A7600X-Cat-Hat pi connect.png
注意要将跳线帽跳到B处，3V3-PWR

树莓派串口配置

由于树莓派串口默认用于终端调试，如需使用串口，则需要修改树莓派设置。执行如下命令进入树莓派配置：

sudo raspi-config

选择Interfacing Options ->Serial ->no -> yes，关闭串口调试功能。
需要重启

sudo reboot

打开/boot/config.txt文件，找到如下配置语句使能串口，如果没有，可添加在文件最后面：

enable_uart=1

重启生效

树莓派minicom串口调试

1.将树莓派插入树莓派中
2.安装minicom，minicom是linux平台串口调试工具：

sudo apt-get install minicom

3.执行sudo minicom -D /dev/ttyS0(ttyS0为树莓派3B/3B+/4B，ttyAMA0为树莓派2B/zero的串口)，默认波特率为115200
4.以AT同步测试为例，发送相关指令，如下图所示:

【注意】：minicom可通过按Ctrl+a,再按下z进入设置模式，选择X退出。

树莓派拨号上网

把micro USB线一端接树莓派USB接口，另一端接A7600C1-Cat-1 GSM GPRS-HAT的USB接口
关于树莓派拨号上网相关的具体操作，请参考以下链接：

硬件简介

本例程利用STM32与A7600C1-Cat-1 GSM GPRS-HAT进行通信时，STM32的主芯片类型为STM32F103ZET6,当然也可以是其他芯片类型的STM32主板。原理都是一样的，利用UART2与A7600C1-Cat-1 GSM GPRS-HAT进行通信用于发生AT指令，利用UART1与PC端进行通信用于模块反馈信息的打印。
