Mini_PCIe_EVB_User_Guide Confidential / Released 5 / 30 UMTS/HSPA/LTE Module Series Mini PCIe EVB User Guide 1 Introduction This document describes the evaluation board of Mini PCIe card. The Mini PCIe evaluation board is an assistant system integrator for developing and evaluating products based on Quectel Wireless Modules. l e t l c a e i t u n Q ide f n o C Mini_PCIe_EVB_User_Guide Confidential / Released 6 / 30 UMTS/HSPA/LTE Module Series Mini PCIe EVB User Guide 1.1. Safety Information The following safety precautions must be observed during all phases of the operation, such as usage, service or repair of any cellular terminal or mobile incorporating module. Manufacturers of the cellular terminal should send the following safety information to users and operating personnel and to incorporate these guidelines into all manuals supplied with the product. If not so, Quectel does not take on any liability for customer failure to comply with these precautions. Full attention must be given to driving at all times in order to reduce the risk of an accident. Using a mobie while driving (even with a handsfree kit) cause distraction and can lead to an accident. You must comply with laws and regulations restrcting the use of wireless devices while driving. l e t l c a e i t u n Q ide f n o C Switch off the cellular terminal or mobile before boarding an aircraft. Make sure it switched off. The operation of wireless appliances in an aircraft is forbidden to prevent interference with communication systems. Consult the airline staff about the use of wireless devices on boarding the aircraft, if your device offers a Fight Mode which must be enabled prior to boarding an aircraft. Switch off your wireless device when in hospitals or clinics or other health care facilities. These requests are desinged to prevent possible interference with sentitive medical equipment. Cellular terminals or mobiles operate over radio frequency signal and cellular network and cannot be guaranteed to connect in all conditions, for example no mobile fee or an invalid SIM card. While you are in this condition and need emergent help, Please Remember using emergency call. In order to make or receive call, the cellular terminal or mobile must be switched on and in a service area with adequate cellular signal strength. Your cellular terminal or mobile contains a transmitter and receiver. When it is ON , it receives and transmits radio frequency energy. RF interference can occur if it is used close to TV set, radio, computer or other electric equipment. In locations with potencially explosive atmospheres, obey all posted signs to turn off wireless devices such as your phone or other cellular terminals. Areas with potencially exposive atmospheres including fuelling areas, below decks on boats, fuel or chemical transfer or storage facilities, areas where the air contains chemicals or particles such as grain, dust or metal powders.

Connect the Mini PCIe module to the connector J101 on Mini PCIe EVB, charge with USB cable or +5V power adapter and insert SIM card to J303. 2. Switch S201 to ON state, D103 will be light and indicates power supply for EVB is ready. The module will be powered on automatically. D101 (NET_STATUS) will be light after the module registered to the network successfully. Table 13: Indication of D101 Reference D101 NET_STATUS State Description Always ON Registered to network Always OFF Others 4.2. Power Off Mini PCIe Module There are two ways to power off Mini PCIe module. One way is to execute AT command AT+QPOWD (Refer to document [2]). It is the best and safest approach. It logs off the network and saves data before shutdown. But Mini PCIe module will be powered on again after shutdown. The other way is to switch S201 (POWER) to OFF state directly, but this way is not recommended. Please switch S201 to OFF after shutting down the module by executing AT command AT+QPOWD.

Reset Mini PCIe Module The emergency restart option is only used in case of emergency. For example, the software does not respond for more than 5 seconds due to some serious problems. Pressing the key S101 for more than 150ms then releasing will reset the Mini PCIe module. This may cause the loss of information stored in the memory since the reset has been initialized. l e t l c a e i t u n Q ide f n o C 4.4. Communication via USB or UART Interface 4.4.1. Communication via USB Interface 1. 2. 3. Power on the Mini PCIe module. Connect EVB and PC with USB cable through USB interface, refer to document [1] to install USB driver from the Driver Disk. Configure AT Command Window, select correct communication port, and operate the Mini PCIe module via AT commands. 4.4.2. Communication via UART Interface 1. 2. 3. 4. Install the USB-to-RS232 driver from the Driver Disk. Connect the UART interface to PC with USB-to-RS232 converter cable. Configure AT Command configuration tool, set correct baud rate (such as 115200bps) and COM number which can be checked by the Device Manager on PC. Power on the Mini PCIe module and operate the module via AT commands. 4.5. Firmware Upgrade Mini PCIe Module upgrades firmware via USB port by default, please follow the procedures below to upgrade firmware. 1. 2. 3. 4. Open the firmware upgrade tool “QFlash” in the PC and power on the Mini PCIe module. Click the “COM Port” dropdown list and select the USB DM port. Click the “Load FW Files” button to choose the firmware document package. Click the “Start” button to upgrade the firmware.
