4. Persediaan dan Pemasangan

The A7670E-LASE development board is designed for ease of integration. Follow these steps for initial setup:

1. Masukkan Kad SIM: Ensure the module is powered off. Carefully insert a MIRCO SIM card into the designated slot on the board.
2. Sambungkan Kuasa: Connect a USB power source (5-16V DC) to the Micro USB port on the board.
3. Antenna Connection (Optional): If using an external antenna, connect it to the appropriate connector on the board.

4.1 Power-On Solutions

The module supports two power-on methods:

1. Default Power-On: The product is configured for default automatic boot.
2. POWRKEY Power-On Solution: For hardware developers requiring a specific power-on sequence, it is necessary to remove the material (components) with bit numbers R3 and C5 on the PWK/RST pin. This modification allows for a controlled power-on via the POWRKEY pin.

Special Note: The default automatic boot is standard. The POWRKEY boot solution requires hardware modification and is not considered a product defect.

5. Arahan Operasi

Once the module is powered on, the Power/Network LED will indicate its status. The module can be interfaced via USB or UART.

• Pemasangan Pemandu: Install the necessary USB drivers for your operating system (Windows, Linux, Android) to enable communication with the module via USB.
• Perintah AT: Utilize AT commands for controlling the module's functions, such as network registration, data transmission, and voice calls. The AT command set is compatible with SIM7500/SIM7600 series modules.
• Protokol Rangkaian: The module supports various network protocols including TCP/IP, IPV4/IPV6, FTP/FTPS, HTTP/HTTPS, DNS, RNDIS, ECM, and PPP, allowing for flexible data communication.
