4 Illustration:
4.1 Turn on Module:
(1) Keep S101, S102 and S105 at ‘OFF’ state, connect the Module-TE to the 60pins connector on SIM900 EVB, plug in 5V DC adapter, switch S105 to ‘ON’ state;.
(2) Press the S103 (PWRKEY) for more than 1 second and then release, the module will power on.
After the module is powered on, the LED D202 will flash at a certain frequency. Through the state of LED (D202), you can judge registering status of the module. For detailed description, please refer to the module HD spec.
Note: You should equip four sets of screws for better grounding to achieve a better performance.
4.2 Turn off Module
Press the S103 (PWRKEY) for about 2 seconds, the module will be turned off.
After the module is turned off, the LED D201 and D202 will be off.
4.3 Registering Network and Making a Call
(1) Connect the antenna to the Module-TE, insert SIM card and earphone.
(2) Connect the serial port cable to the MAIN serial port; Open the Hyper Terminal (AT command windows) on your computer.
First, check the serial port number:
My computer (right click) →Manage → Device Manager → Ports (COM&LPT)

c) Set the baud rate and flow control
User can set the baud rate from 1200bps to 115200bps, and the flow control set to ‘None’
(3) Act on the step of running which mentioned above, power on the module, typing the AT command in the HyperTerminal, and then the module will execute its corresponding function. a) Connect the module

Software Upgrade
Customer could upgrade module’s firmware through USB or UART interface.
1) Upgrade module’s firmware through USB port z Keep S101, S102 and S105 at ‘OFF’ state, connect the Module-TE to the 60pins connector on SIM900 EVB; z Plug in 5V DC adapter to EVB, switch S105 to ‘ON’ state; keep S101 and S102 at
‘OFF’ state; z Connect SIM800H/L-TE module to pc through USB cable; z Insert the USB will be prompted to install the driver for the first time; z
Open the upgrade tool, click ”Start All” button; z
Again insert the USB, the upgrade tool will automatically enter the upgrade process;
Note : Must be properly installed MTK chip driver.
2) Upgrade module’s firmware through UART port z Keep S101, S102 and S105 at ‘OFF’ state, connect the Module-TE to the 60pins connector on SIM900 EVB; z Plug in 5V DC adapter to EVB; z Connect EVB MAIN UART port and the PC USB port through the USB-to-RS232 cable; z Open the upgrade tool, click ‘Start All’ button after configuration options z Switch S105 and S102 to ‘On’ state, the upgrade tool will automatically enter the upgrade process.
