This step is for Mac OS users only! See Step 2 to check the Duet is connected and the Serial Port name. Windows and Linux users skip this step.

To connect to your Duet, we recommend using SerialTools from the AppStore. Install SerialTools and run it. Select the Duet from the 'Serial Port' drop down; it will be named something like "usbmodem1411". Baud rate should be 115200, and Local Echo should be ticked. Click 'Connect' to connect.

It is also possible to use the built-in 'screen' terminal application. However, you cannot see the commands you type in, and the responses from the Duet are not formatted nicely on the screen. If you want to use 'screen', do this:

Open Applications > Utilities > Terminal. Run screen /dev/tty.usbmodem1411 115200, replacing "usbmodem1411" with the Serial Port name for your Mac, if different (see Step 2).

You should see a blank screen, but see note on Duet 2 WiFi below. Hit enter and you should see OK returned. You are connected successfully.

If you get an error, Sorry, could not find a PTY. unplug the USB, plug it back in and try again.

No matter which connection method you use, if you are connecting to a Duet 2 WiFi or Duet 3 Mini 5+ WiFi, you may see lots of "WiFi reported error: no known networks found" messages. Don't worry, that's normal, and it means that the Duet is working!

At certain points in these instructions, you may need to use quote marks in commands. Any double quotation marks must be sent as straight double quotation marks. To enable straight double quotation marks go to System Preferences > Keyboard > Text. Then under the Double Quotes drop down, select straight double quotations.
