SIM840W EVB User Guide SIM840W-EVB_UGD_V1.00 20 2011-06-22 6. Illustration: 6.1 Running: (1) Connect the SIM840W-TE with SIM840W module to the 60pins connector on SIM840W EVB, inserting 5V direct current source adapter, switching the S101,S102 switch on off state, S105 switch on ON state; (2) Press the PWRKEY for about 1 second, and then SIM840W module begins running. You can see the light Q3 on the EVB flashing at a certain frequency. By the state, you can judge whether the EVB and SIM840W can run or not. No function and test can be executed when we have not connected necessary accessories. 6.2 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 SIM840W is 115200, 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 SIM840W-TE with SIM840W module using an antenna transmit line, insert SIM card into the SIM card interface, 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 SIM840W module will execute its corresponding function. 6.3 Downloading Connect the serial port line to the MAIN serial port, connect the direct current source adapter, run the download program and press the START key, then switch the S105 switch on ON state, S102 switch on ON state, then EVB provide the function of downloading. 6.4 Turns off Turn off SIM840W module: press the PWRKEY for about 2 second, SIM840W module will be turned off.
