Serial connection to omega onion pro 2
I am following the following instructions to serially connect to an omega onion pro 2, but cannot get it to work. Please note for step 2, I am unable to find Silicon Labs CP210x USB to UART Bridge, but instead only see COM3. So I use 3 while configuring PuTTy, but don't see the omega connected.
I am using a DTECH USB to UART TTL Cable Model No. DT-6552 to serially connect. I am also utilizing RX+, TX-, and GND.
Serial on a Windows Device
Step 1: Download Drivers
Download and install the Silicon Labs CP2102 driver for Windows.
Step 2: Find Serial Device
Plug in your Omega & Dock and run Device Manager (Start > Enter “Device Manager” and press ENTER), look for Silicon Labs CP210x USB to UART Bridge under Ports (COM & LPT), and take note of the COM number in bracket.
Step 3: Download Putty
Step 4: Configure the Terminal Program
Open up PuTTy, select Serial for Connection type, enter the COM number noted down in Step 2 as Serial line, and enter 115200 for the speed.
Step 5: Connect
Click on the Open button to connect to the Omega via the serial terminal.
Log in through serial terminal
Thank you so much!

@Antony Are you using the Omega2 Pro?
If so, it already has a USB to Serial chip (H in diagram) that's accessible through the Micro-USB port (F in diagram):
Take a look at the Omega2 Pro Getting Started Guide for more info: https://onion.io/omega2-pro-get-started/
And there's also the Omega2 Pro documentation page for information on the hardware: http://docs.onion.io/omega2-docs/omega2-pro.html
@Lazar-Demin Thank you, this helped
