Test & Configure

Mac OS X

If you are using a Mac, then all you need to do is open a Terminal window and issue the command:

screen /dev/cu.PL2303-00001004 115200

The device will have a slightly different name to mine. So, type the line above as far as "cu.PL" then press the TAB key to auto-complete to whatever your device is called, before adding 115200 (which is the baud rate) to the end.

You can also try screen /dev/cu.PL2303* 115200or screen /dev/cu.usbserial 115200 To have the shell complete the file name for you

You may need to disable system integrity protection (according to feedback from a tutorial-reader)


If you are using Linux then use the command:

sudo screen /dev/ttyUSB0 115200

To start communication with the Pi, press ENTER and you should see the login prompt from the Pi.

Here it is running on a Mac.

and here is what it looks like in Ubuntu.


If you are using a PC, then before you start Putty, you need to know which com port is being used for the cable. You can find this by looking in the Ports section of the Windows Device Manager.

The Device Manager is accessible from the Control Panel under System.

In this case it is COM7 that is in use.

Now start Putty and you will see a connection window.

Select a connection type of "Serial" from the radio buttons, then set the speed to 115200 and the serial line to COM7

Finally click 'Open' to connect. Remember to press ENTER to start communications.

For a new installation of Raspbian, the default username is pi and the default password is raspberry

Thats it! You are connected and can use the command line to navigate around your Pi.

In the next session we will look at using SSH as another means of connecting to your Pi over your local network.
