Adding a 3-Wire Device
To configure a device, select the Devices button to open the Devices window.
Select “Add a device.”
Select the 3-wire Devices.
Select the 3-wire Device that you are using. This example shows a Limit Switch.
Note: 3-wire Devices include the Limit Switch, Bumper Switch, Encoder, Range Finder, Line Tracker, Light, Potentiometer, LED, Gyro, Motor-393, Servo, Accelerometer-2G, and Accelerometer-6G. All devices follow the same configuration process with an additional step for Motor-393. See the bottom of this article for more details.
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.
Changing a 3-Wire Device’s Port
You can change the port number for the 3-Wire Device by selecting the 3-Wire Device in the Devices window.
Select a different port on the Port Selection screen and the port number will turn green. Then select "Done" to submit the change.
Renaming a 3-Wire Device
You can also rename the 3-Wire Device by changing the name in the text box at the top of the Port Selection screen. If you select an invalid name, the text box will highlight red to indicate. Then select "Done" to submit the device changes to the configuration.
If you change the name of 3-Wire 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.
Deleting a 3-Wire Device
3-Wire Devices can also be deleted by selecting the “Delete” option at the bottom of the Port Selection screen.
Note: If you delete a 3-Wire Device that is already being used in your project, your project will generate an error if you try to download it until you also delete the blocks that were using the deleted device.
Configuring a VEX Motor-393
