5. EVB and accessory equipment
At normal circumstance, the EVB and its accessory are equipped as the Figure 14
Figure 14: EVB and accessory equipment
6. Illustration:
6.1 Running:
(1) Connect the SIM340DTE with SIM340DZ module to the 60pins connector on
SIM340DZ EVB, inserting 5V direct current source adapter, switching the S1 switch on
off state, S2 switch on ON state;
(2) Press the PWRKEY for about 1 second, and then SIM340DZ module begins running.
You can see the light M2 on the EVB flashing at a certain frequency. By the state, you can
judge whether the EVB and SIM340DZ can run or not. No function and test can be executed
when we have not connected necessary accessories.

SIM340DZ EVB User Guide
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 SIM340DZ 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 SIM340DTE with SIM340DZ 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 SIM340DZ 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 S1 switch on ON
state, S2 switch on ON state, then EVB provide the function of downloading.
6.4 Turns off
Turn off SIM340DZ module: press the PWRKEY for about 1 second, SIM340DZ module
will be turned off.
6.5 Charging
Connect the SIM340DTE with SIM340DZ module to the 60pin connector interface and
the external battery to charging interface, which have been provided on the EVB. Insert the
direct current source adapter; switch shifter S2 on the OFF state, shifter S3 on the ON state,
then the SIM340DZ will go to the charging state.
