6 Quickly start
6.1 Running
There are two ways to provide power supply to SIM5320 module: one is to use the 6V power supply provided in the EVB kit; the other is to use USB port of personal computer.
(1) When user use the power supply, if user insert 6V DC source adapter, user should connect
ADAPTER_VBAT pin and VBAT pin on the EVB board; then insert a valued SIM card and check if the antenna is connected, and make sure that RF control switch is set to ON; finally press the on/off switch for about 1 second, and then SIM5320 module will begin running.
(2) Another option is to use USB port of Computer as power supply. To do so, user need to connect USB_VBAT pin and VBAT pin on the EVB board, and make sure that RF control switch is set to ON. Firstly insert the sim card and connect the antenna, then connect the PC with USB-to-USB cable and press the Power_ON button for one second, then SIM5320 will start running.
User can see the light on the EVB flashing at a certain frequency about 1.25Hz. By the state, user can judge whether the EVB and SIM5320 is running or not. No function and test can be executed if user has not connected necessary accessories.
NOTE: This EVB board supports USB power supply when user connects USB_VBAT and
VBAT together.
6.2 Installing Driver
There are 3 ways to connect the module to user’s computer and communicate via HyperTerminal:
(1) Using USB-TO-USB cable;
(2) Using UART-TO-USB cable;
(3) Using UART-TO-UART cable.
In the first case, user need install the module USB driver, which can be got from our FAE or sales;
For the UART to USB driver, user may get it from the CD in the EVB kit; If user use UART to
UART cable, there are certain points to be noticed. One can use UART to UART cable in EVB kit, if the customers want to use their own UART to UART cable, please make sure that the pin sequences of it is same as those of cable in EVB kit, pin sequences of which are shown in Figure
9.

6.3 Connecting Net and calling
Once user installs the driver, user can follow steps below to connect to Network.
(1) When user use a UART-UART cable, user need to connect the serial port line to the serial port, open the HyperTerminal (AT command windows) on user’s Personal computer. The location of the HyperTerminal in windows2000/XP/Vista can be found from START→accessory→ communication→HyperTerminal. Please set the correct Baud Rate and COM port number, the
Baud Rate of SIM5320 is 115200, and the COM port number is based on which UART port user’s serial port line is inserted, user should select the port such as COM1 or COM2 etc.
(2) Connect the antenna to the SIM5320 module using an antenna transmit line, insert SIM card into the SIM card holder, and insert handset into its sockets.
(3) Follow the steps of running which has been mentioned above in Sector 5.1, power on the system, type the AT command from the HyperTerminal, and then the SIM5320 module will execute its corresponding function. For example, if user type “AT”, then it should respond “OK”; if user type “ATI”, it should display product identification information.
(4) If user want to use USB to USB cable, user need to connect the cable to USB port of the module and the computer, then follow step 1~3.
(5) If user use UART to USB cable, user need to connect the cable to module serial port and the
USB port of the computer, then follow step 1~3.
6.4 Downloading
Connect the USB port line to the USB port, connect the direct current source adapter, run the download program, and choose the correct image, please follow the QDL downloading menu for the operation. Update procedure is described in the figure below.

6.5 Turning off
Press the POWER_ON for about 1 second, SIM5320 module will be turned off.
NOTE: If user uses USB to power on the module, just disconnect the USB cable to turn off.
6.6 Measuring the current consumption
User can measure
SIM5320 current consumption in the sleep mode on our EVB. User need to follow steps.
(1) Remove the jumper from J202, and provide a 3.8V DC power supply (such as: Agilent 66319B) for VBAT on SIM5320 EVB;
(2) Install a SIM card and a RF antenna;
(3) Shutdown UART by S204;
(4) Remove the USB cable;
(5) Power on SIM5320;
SIM5320 will enter sleep mode automatically. User can measure
SIM5320 current consumption.
Test report is described in the figure below.
