6. Illustration:
6.1 Running:
(1) Connect the SIM900-TE with SIM900 module to the 60pins connector on SIM900 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 SIM900 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 SIM900 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 SIM900 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 SIM900-TE with SIM900 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 SIM900 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 SIM900 module: press the PWRKEY for about 2 second, SIM900 module will be
turned off.
