SCOPE
This document give the usage of SIM5218 EVB, user can get useful information about the
SIM5218 EVB quickly through this document.
The Debug board is designed for custom to design their applications by using the 3G module
SIM5218 easily.
All the functions of the SIM5218 can be used by this board. One can use UART, USB interface to
communicate with the SIM5218, and can design their camera phone by SIM5218. There is one
UART interface, one USB 2.0 interface, one SIM card interface, one T-FLASH card interface,
three camera interfaces, and four audio interfaces on the board and expand I/O interfaces.
One can connect the UART and the USB interface to a computer directly.

4 EVB and accessory equipment
At normal circumstance, the EVB and its accessory are equipped as the Figure below.
Figure 15: EVB and accessory equipment
5 Illustration
5.1 Running
(1) Connect the SIM5218 module to the 70pins connector on SIM5218 EVB, inserting 6V direct
current source adapter, you should connect J7 and J19 pin on the board;
(2) Insert a valued SIM card and check the antenna is connected;
(3) Press the on/off switch for about 1 second, and then SIM5218 module begins running.
You can see the light on the EVB flashing at a certain frequency. By the state, you can judge
whether the EVB and SIM5218 can run or not. No function and test can be executed when we
have not connected necessary accessories.
NOTE: This EVB board supports USB power on when you connect J12 and J19 together.
SIM5218 EVB User Guide 09.12.2008

SIM5218 EVB User Guide
5.2 Connecting Net and calling
(1) Connect the serial port line to the serial port, open the HyperTerminal (AT command windows)
on your Personal computer, the location of the HyperTerminal in windows2000 is
START→accessory→communication→HyperTerminal. Set correct Baud Rate and COM number.
The Baud Rate of SIM5218 is 115200, and the COM number based on which USB port your serial
port line insert in, you should select such as COM1 or COM2 etc.
(2) Connect the antenna to the SIM5218 module using an antenna transmit line, insert SIM card
into the SIM card interface, and insert headphones or headset into its interface.
(3) Act on the step of running which mentioned above, power on the system, typing the AT
command in the HyperTerminal, and then the SIM5218 module will execute its corresponding
function.
(4) If you want to use USB port, you should setup the drivers for the USB modem, after that, you
will see 3 virtual serial ports in device list in windows system. Now you can connect the device
following step 1~3. The performance of the virtual serial port is as same as the serial port.
5.3 Downloading
Connect the USB port line to the USB port, connect the direct current source adapter, run the
download program, select the Diag port on USB interface (such as COM3,COM4,etc), and choose
the correct image, press the start button on the program to enter downloading mode.
NOTE: You should enter download mode using AT command AT+CSWITCHTEST=1. Please
refer ATC specification for more information.
5.4 Turns off
Press the PWRKEY for about 1 second, SIM5218 module will be turned off.
NOTE: If you use USB to power on the module, just disconnect the USB cable to turn off.
