Full attention must be given to driving at all times in order to reduce the risk of an accident. Using a mobile while driving (even with a handsfree kit) causes distraction and can lead to an accident. You must comply with laws and regulations restricting the use of wireless devices while driving.

Switch off the cellular terminal or mobile before boarding an aircraft. Make sure it is switched off. The operation of wireless appliances in an aircraft is forbidden, so as to prevent interference with communication systems. Consult the airline staff about the use of wireless devices on boarding the aircraft, if your device offers an Airplane Mode which must be enabled prior to boarding an aircraft.

Switch off your wireless device when in hospitals, clinics or other health care facilities. These requests are designed to prevent possible interference with sensitive medical equipment.

Cellular terminals or mobiles operating over radio frequency signal and cellular network cannot be guaranteed to connect in all conditions, for example no mobile fee or with an invalid USIM/SIM card. While you are in this condition and need emergent help, please remember using emergency call. In order to make or receive a call, the cellular terminal or mobile must be switched on and in a service area with adequate cellular signal strength.

1 Introduction

This document describes how to use the evaluation board of UMTS<E modules and Wi-Fi modules. It is an assistant tool for engineers to develop and test Quectel UMTS, LTE and Wi-Fi modules.

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 UMTS<E and Wi-Fi modules. Manufacturers of the cellular terminal should send the following safety information to users and operating personnel, and incorporate these guidelines into all manuals supplied with the product. If not so, Quectel assumes no liability for the customer‟s failure to comply with these precautions.

UMTS<E_EVB_User_Guide Confidential / Released 7 / 44

UMTS/HSPA/LTE Module Series

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 potentially explosive atmospheres, obey all posted signs to turn off wireless devices such as your phone or other cellular terminals. Areas with potentially explosive atmospheres include 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, etc.

4.5. Audio Interfaces

Quectel UMTS<E EVB provides one digital audio codec board interface (PCM) J501 and three analog audio interfaces J601, J602 and J603. This chapter gives a detailed introduction on these audio interfaces.

4.5.1. Digital Audio Codec Board Interface (J501)

The UMTS<E EVB supports two different kinds of external digital audio codecs named ALC5616 and TLV320AIC3104. The codec circuit is assembled on an independent small board which can be interconnected with EVB by the BTB connector J501.

Customers can select different codecs according to their own application demands, and also can use AT command to switch between codecs. For example, AT+QDAI=3 is used to switch codec from TLV320AIC3104 to ALC5616, and AT+QDAI=5 is used to switch codec from ALC5616 to TLV320AIC3104. For more details about the AT commands, please refer to document [4] and document [5].

The following figure shows a reference circuit design for digital audio codecs, and Figure 13 shows the connection between codec board and EVB.

5 Operation Procedures Illustration

This chapter introduces how to use the UMTS<E EVB for testing and evaluation of Quectel UMTS<E modules and Wi-Fi modules.

5.1. Power on UMTS<E and Wi-Fi Modules

 Power on UMTS<E module

1. Connect the UMTS<E TE-A to the connectors (J101 and J102) on EVB.

2. Insert a USIM card into the USIM card connector on EVB, and connect the antennas to UMTS<E TE-A.

3. Connect the EVB to a 5V power adapter, or connect the EVB to PC via USB cable.

4. Switch S201 to ON state, then D209 will be light. Press the S302 (PWRKEY) for at least 100ms, then

the UMTS<E module will be powered on and D205 (STATUS) will be light.

 Power on Wi-Fi module

1. Make sure the EC2x module is powered on, if there is a need to test the Wi-Fi function of EC2x modules.

2. Connect the FC20 TE-A to the connectors (J901 and J902) on EVB, and connect the Wi-Fi antenna to FC20 TE-A.

3. Connect the FC20 TE-A to PC via Ethernet cable.

4. Send AT+QWIFI=1 command to EC2x module to enable power supply for FC20 module. For more details, please refer to document [3]. Before sending the command, please make sure the EVB has been connected to PC via USB cable.

The following table shows the UMTS<E module‟s network status which can be judged by D206 and D208.

5.3. Firmware Upgrade

Quectel UMTS<E module upgrades firmware via USB port by default, please follow the procedures below to upgrade firmware.

1. Install and open the firmware upgrade tool QFlash on PC and then power on the UMTS<E module according to the procedures mentioned in Chapter 5.1.

2. Click the “COM Port” dropdown list and select the USB DM port.

3. Click the “Load FW Files” button to choose the firmware package.

4. Click the “Start” button to upgrade the firmware.

Figure 36: Configurations for Firmware Upgrade

5.4. Reset UMTS<E Modules

The emergency reset option is only used in case of emergency. For example, the software does not respond for more than 5s due to some serious problems.

Press the button S303 for more than 150ms then release it to reset UMTS<E module. However, this may causes the loss of information stored in the memory as the reset module has been initialized.

5.5. Power off UMTS<E and Wi-Fi Modules

 Power off UMTS<E module

There are two ways to power off UMTS<E module.

One way is to execute AT command AT+QPOWD. This is the best and the safest way. The module will log off from the network and save data before shutdown, but it will be powered on again after shutdown. For more details about the AT command, please refer to document [4] and document [5].

The other way is to press down S302 for at least 0.6s, the UMTS<E module will be shut down.

 Power off Wi-Fi module

AT+QWIFI=0 command can be used to power off FC20 modules. For more details, please refer to
