5 Quickly start
5.1 Running
User can use the 6V DC adapter provided in the EVB kit to provide power supply to SIM7100A
module.
First user should insert a 6V DC adapter and the jumper should be connected; then insert a valued
SIM card and check if the antenna is connected, and make sure that RF control switch is set to ON;
finally press the power on/off switch for about 1 second, and then SIM7100A module will begin
running.
User can see the light on the EVB flashing at a certain frequency about 1.25Hz. By the state,
user can judge whether the EVB and SIM7100A is running or not. No function and test can be
executed if user has not connected necessary accessories.
5.2 Installing Driver
There are 3 ways to connect the module to user’s computer and communicate via HyperTerminal:
(1) Using USB-TO-USB cable;
(2) Using UART-TO-USB cable;
(3) Using UART-TO-UART cable.
In the first case, user need install the module USB driver, which can be got from our FAE or sales;
For the UART to USB driver, user may get it from the CD in the EVB kit; If user use UART to
UART cable, there are certain points to be noticed. One can use UART to UART cable in EVB kit,
if the customers want to use their own UART to UART cable, please make sure that the pin
sequences of it is same as those of cable in EVB kit, pin sequences are shown in Figure 9.
5.3 Connecting Net and calling
SIM7100A EVB user Guide

Smart Machine Smart Decision
Once user installs the driver, user can follow steps below to connect to Network.
(1) User should connect the EVB Kit to PC, then open the HyperTerminal (AT command windows)
on user’s Personal computer. The location of the HyperTerminal in windows2000/XP/Vista can
be found from START→accessory→ communication→HyperTerminal. Please set the correct
Baud Rate and COM port number, the Baud Rate of SIM7100A is 115200, and the COM port
number is based on which UART port user’s serial port line is inserted, user should select the port
such as COM1 or COM2 etc.
(2) Connect the antenna to the SIM7100A module using an antenna transmit line, insert SIM card
into the SIM card socket, and insert the handset.
(3) Follow the steps of running which has been mentioned above in Sector 5.1, power on the
system, type the AT command from the HyperTerminal, and then the SIM7100A module will
execute its corresponding function. For example, if user type “AT”, then it should respond “OK”;
if user type “ATI”, it should display product identification information.
(4) If user want to use USB to USB cable, user need to connect the cable to USB port of the
module and the computer, then follow step 1~3.
(5) If user use UART to USB cable, user need to connect the cable to module serial port and the
USB port of the computer, then follow step 1~3.
5.4 Downloading
Connect the USB port line to the USB port, connect the direct current source adapter, run the
download program, and choose the correct image, please follow the QDL downloading menu for
the operation. Update procedure is described in the figure below.

5.5 Turning off
Press the POWER key for about 1 second, SIM7100A module will be turned off.
5.6 Measuring the current consumption
User can measure SIM7100A current consumption in the sleep mode on our EVB. User need to
follow steps.
(1) Remove the jumper from J203, and provide a 3.8V DC power supply (such as: Agilent 66319B)
for VBAT on SIM7100A EVB;
(2) Install a SIM card and a RF antenna;
(3) Shutdown UART by S401;
(4) Remove the USB cable;
(5) Power on SIM7100A;
SIM7100A will enter sleep mode automatically. User can measure SIM7100A current
consumption. Test report is described in the figure below.
