1. Hardware configuration
1.1. Hardware configuration
This module comes with GSM antenna, LTE antenna and micro USB cable. Besides these you should
prepare a 4G sim card and a microphone cable with microphone:
1) Insert the SIM card to the card slot, Insert the headphone cable and connect the LTE antenna.
2) Connect the USB interface of SIM7600E-H 4G HAT to PC with a micro USB cable. Then the PWR
indicator will keep bright.
3) Press the PWRKEY button and hold for 1s, the NET indicator will blink as below. Generally, the
NET indicator will fast flash firstly (1 time per second), which means that the module has not
logged in the Network. After logging in, the indicator become to flash slowly (1 time every three
seconds). Up to the local LTE network, this process that logging in will last several seconds to
dozens of seconds.
\
If you take too much time to log in and failed, please check that whether the LTE antenna is
connected correctly, and whether the SIM card is usable and insert correctly.
4) Install SIM7600 driver (windows driver: www.waveshare.com/wiki/File:SIM7X00-Driver.7z)
Open Device Manager to get the corresponding COM port number of SIM7600. For example, the
AT Port is COM19 as below. Users need to choose the correct port according to the Manager.

LOCAL VIRTUAL SEVERS SETTINGS
Virtual servers define the mapping between service ports of WAN and web servers of
LAN. All requests from Internet to service ports of WAN will be redirected to the
computer (web servers of LAN) specified by the server IP. (see your router’s guide
manual)
4) Log in Management Console of your router with browser (read your router’s guide manual for
specific address)
5) Set Port：1822 (The Port can’t be conflict to other’s. Here we set 1822)
Set LAN IP address of your computer (you can run CMD on your computer, and execute command
ipconfig to enquiry the address of IPv4), 192.168.6.168 as examples
6) You can search “IP” on browser to get your WAN IP address.

Choose Advanced Options -> Serial -> no , to disable Linux’s use of console UART
Open /boot/config.txt file, find the below statement and uncomment it to enable the UART. You can
directly append it at the end of file as well.
enable_uart=1
Then reboot.
3.3. Init the Raspberry Pi
1、 Download the raspberry pi demo code and copy the SIM7600X folder to /home/pi/ directory.
2、 Enter /home/pi/ directory,execute command:
chmod 777 sim7600_4G_hat_init
