Select which port the device is attached to on the VEX V5 Brain. Ports that are already configured for other devices will be unavailable. Once the port has been selected, select ‘Done’ to submit the device to the configuration or ‘Cancel’ to return back to the Devices menu.

Note: Selecting ‘Cancel’ will undo any changes you have made to the device and will not be a part of the configuration.

If you change the port of a device that is already being used in your project, you will need to update the device's name in the block to the new name using the drop down.


Renaming a Digital In or Digital Out 3-Wire Device

The device can be deleted by selecting the ‘Delete’ option at the bottom of the Port Selection screen.
