5. Illustration
5.1 SIMCom TE installation and uninstallation
Figure12: TE assembly
Install TE board:
1) there have four studs on board near connectors. It’s easy to put TE in correct position without making
mistake.
2) take care of TE SMA connector direction;
3) take care of the mark for TE direction on EVB board.
Uninstall and replace TE board:
1) it’s a little hard to remove TE board from EVB connector, because they are connected closely.
2) Take care with power to remove from SMA connector side slowly.

5.2 Power on Module:
1) Connect the SIMCOM-TE to the 2x60pins connector on EVB, plug in 5V DC adapter, switch S201 to
“ON” state; keep S401 to “ON” position.
2) Press the POWER_ON button for more than 1.5 second and then release, SIMCOM module power
on.After the module is on, the LED light D402 will be bright ,and the LED light D401will blink at a certain
frequency. Through the state of LED, you can judge registering status of the module. For detailed
description, please refer to SIMCOM HD document.
5.3 Registering Network and Making a Call
1) Install antenna to TE board, insert SIM card.
2) Connect the USB cable to the USB jack; launch the Hyper Terminal in computer.
3) Check the serial port number from Device Manager list.
4) Use the Hyper Terminal to make a call from module as following:
a) Launch hyper terminal
