these precautions.
Be assure the use of the product conforms to the national safety and
environmental regulations, and is allowed in the country and in the environment
required.
Keep away from explosive and flammable materials. The use of electronic
products in extreme power supply conditions and locations with potentially
explosive atmospheres may cause fire and explosion hazards.
The product has to be powered by a stabilized voltage source, and the wiring
shall conform to security and fire prevention regulations.
Proper ESD handling procedures must be applied throughout the mounting,
handling and operation of any application that incorporates the module to avoid
ESD damages.

EVB Operation Procedures
This chapter mainly illustrates the operation procedures of L26-T EVB.
4.1. Communication via Micro-USB Interface
Step 1: Connect the EVB and the PC with a Micro-USB cable through Micro-USB interface, and then
switch POWER to ON state to power on the EVB.
Step 2: Run the USB flash drive on PC to install the USB driver. The USB port numbers can be viewed
in Device Manager of the PC after the USB driver is installed, as shown below.
Figure 9: USB Ports
Step 3: Install and then use the tool QCOM provided by Quectel to realize the communication between
L26-T module and the PC.
The following figure shows the COM Port Setting of QCOM: select the correct “COM Port” (USB
Port shown in the above figure) and set the correct “Baudrate” (the default value: 9600bps). For
more details about the usage of QCOM, please refer to document [4].
