6.4.2 Firmware updating procedure

SW-BA-e-1710
When the driver is installed, connect the sound
level meter to the computer using the USB cable.
The Device Manager will show a new device called
Silicon Labs CP210x USB to UART Bridge
(COMx).
☆ Hint: When the sound level meter connects to
the computer, power it up using an external power
supply.
FlashTool Wizard used for firmware updating is very user-
friendly. You just have to follow the procedure step by
step.
Start FlashTool Wizard and choose the language.
Step 1: Prepare the firmware update list.
Step 2: Install the driver. Ship this step if the driver is al-
ready installed.
Step 3: Connect the sound level meter to the computer
as per the user requirements. Note that the sound level
meter requires an external power supply. If the driver
works properly, it will automatically select the CP210x
port. The standard baud rate is 115,200 bps, but it de-
pends on the computer. A higher baud rate allows for a
faster updating procedure.
