The purpose of this blog post is to show the steps required on how to add the UC-232a USB to serial cable to your Apple MAC and then how to configure a profile so you don’t have to enter the commands again. I have had to do this a lot recently due to issues with my MAC so I thought I would document my own workflow on this process.
Step 1: Go here and download the required drivers under Support & DownloadsY
Step 2: Install the driver for the UC232a USB to serial cable it will require a reboot of your computer
Step 3: Open a terminal session, press command key and space then type “terminal” once located hit enter
Step 4: plug in UC-232AC USB to serial adapter into MAC
Step 5: In terminal program type:
$ ls /dev/cu.*
Located the /dev/cu.UC-232AC as per below.
Step 6: Type,
$ screen /dev/cu.UC-232AC 9600
And Now you should have CLU access to your device
If the below message is displayed in Terminal, dis-connect and reconnect your USB to serial cable ;
Now to create a profile so you do not have to continually enter the commands
Step 6: Click on Terminal and select ” Preferences…”
Step 7: In the ” Profiles section” Click “+” icon located bottom left corner
Step 8: Type in your profile name i.e ” USB Serial”
Step 9 : In the shell tab that is part of your new profile you created, click “Run command” and enter in the text field: screen /dev/cu.UC-232AC 9600
Then close the window
Step 10: Right click on the terminal icon and go to ” New window with Profile” and select the profile you created
Now you should have CLI access to your device.
If the below message is displayed in Terminal disconnect and reconnect your usb to serial cable
That is it.
