3.4 SIM card interface

The SIM700-EVB contains a dedicated smart card interface, conforming to the ISO/IEC7816-3 (Identification Card) standard but only supporting the subset required for GSM phase 2+ operation. This interface is fully compliant with GSM 11.11 recommendations concerning the SIM functionality.

The SIM interface is available through the 80-pin connector connect to a stand-alone SIM card holder.

SIM700-EVB_UGD_V1.04 02.16.2009 13


Figure 8: SIM card interface

Notes: This interface is compatible 3V and 1.8V on the SIM700-EVB, it can be recognize automatically by software. 5V SIM card can be driven with production unit using an external level shifter.

The SIM Interface module functions as an asynchronous serial communications port. It is half duplex and therefore allows sharing of hardware between receive and transmit modes. The interface is symmetric, with the same timing for transmit and receive.

5.1 Running

(1) Connect the SIM700 module to the 80 pins connector on SIM700-EVB, inserting 5V direct current source adapter, switching the S401 S201 switch on off state, S402 switch on ON state;

(2) Press the ON/OFF for about 2 second, and then SIM700 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 SIM700 can run or not. No function and test can be executed when we have not connected necessary accessories.

5.2 Connecting Net and calling

(1) Connect the serial port line to the MAIN 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 SIM700 is 460800, and the COM number based on which USB port your serial port line insert in, you should select such as COM3 or COM4 etc. (2) Connect the antenna to the SIM700 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 SIM700 module will execute its corresponding function.

5.3 Downloading

Connect the serial port line to the MAIN serial port or to USB port (default support USB download) , connect the direct current source adapter, run the download program and press the start Download , then the POWER switch on ON state, DOWNLOAD switch on ON state, and then EVB provide the function of downloading.
