5.1 Running
Figure 15: The running steps of the EVB
The running steps of the EVB board are:
1. Insert USIM card to J207, and connect GPS/GLONASS antenna to J106, Main antenna to
J101 and Auxiliary antenna to J105.
2. Connect USB cable to J203, and USB-UART cable to J205.
3. Connect 5V DC adapter to J201 then the D201 LED will be lighted. If using USB power, this
step is not needed, but need to pay attention to the J202 jumper for power selection.
4. Push the SW301 button to power on the EVB.
5. Check that the D301 LED is lighted or not, to judge whether SIM7100 is powered up or not.

5.2 Connecting to PC
There are 2 ways to connect the module to PC:
1. Connect the J203 of EVB to PC USB port via USB cable ;
2. Connect the J205 of EVB to PC RS232 port via USB-UART cable or UART cable.
In the first case, the module USB driver needs to be installed, and this driver can be got from our
FAE or sale. In the second case, the USB-UART cable driver needs to be installed, and this driver
can be got from the CD in the EVB kit.
After Power up and installing the corresponding driver, the HyperTerminal tool can be used to
access the SIM7100 via the virtual COM from USB or the physical UART COM.
NOTE: the HyperTerminal in windows2000/XP/Vista can be found at
START—accessory—communication menu. Please set the Baud Rate to115200bps for the
SIM7100 and the corresponding COM port number, such as COM1 or COM2 etc.
