Black BeagleBone Serial connection

Serial console is basically a remote terminal for the BeagleBone board. This way we can execute shell commands on BeagleBone board from our PC or laptop, and see its output. It is also useful when there are problems with the Linux installation on our board.

To do so, we will need two things:

• Special cable for serial console, to connect our board to the PC (USB to Serial UART TTL 3.3v serial cable).
• Special software, to be able to manipulate the board shell via the cable. (MobaXterm, minicom, kermit, gtkterm, PuTTY, etc)
  The pinout of the serial-port is like that figure below. Connect the USB-to-TTL to the J1 headers on your BeagleBone Black as shown:

Function	USB-to-TTL Cable	BeagleBone
Ground	GND wire	Pin 1 J1 Header GND
TX→RX	TX wire	Pin 4 J1 Header RXD
RX←TX	RX wire	Pin 5 J1 Header TXD

With MobaXterm installed, you can establish a serial communication with your BeagleBone Black.

1. open session
2. choose serial
3. click to the port that plug into your pc (on windows, you can check the Device manager to see COMport)
4. set the Speed is 115200 baudrate. Bits=8, Parity=N, stopbits=1,handshake=none After the setup, you would be able to log in bbb serial console.
