Follow the steps below to set up a serial connection to your Azure Percept DK through PuTTY.
If you have a private preview dev kit we do NOT recommend attempting to connect your dev kit over serial except in extreme failure cases (e.g. you bricked your device). Connecting over serial requires that the private preview dev kit be disassembled to access the GPIO pins. Taking apart the carrier board enclosure is very difficult and could break the Wi-Fi antenna cables.

Start the serial connection
Connect the USB to TTL serial cable to the three GPIO pins on the motherboard as shown below.
Power on your dev kit and connect the USB side of the serial cable to your PC.
In Windows, go to Start -> Windows Update settings -> View optional updates -> Driver updates. Look for a Serial to USB update in the list, check the box next to it, and select Download and Install.
Next, open the Windows Device Manager (Start -> Device Manager). Go to Ports and select USB to UART to open Properties. Note which COM port your device is connected to.
Select the Port Settings tab. Make sure Bits per second is set to 115200.
Open PuTTY. Enter the following and select Open to connect to your devkit via serial:
- Serial line: COM[port #]
