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 users 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.
