Connect your computer to an ARM custom board using RS232 over USB

We would like to connect our custom ARM SAM4L controller to our computer:


For this we can use a rs232 to USB converter from Prolific.

My adapter has following coding:

blue -> GND
red -> TX
green -> RX

Connect it to your controller crossed so:
blue -> GND
red -> controller RX
green -> controller TX

Plug the converter into your USB port and wait till windows finished the installation. Go to device manager and select the newly existing serial port:

Go into properties and set it like this:
Prolific Einstellungen


Now we open putty and configure here a serial connection using COM4 with the same serial settings:
Putty Einstellungen

Just open the connection now and if your controller prints now some characters to the serial device you should see it in the terminal.
