VEX Cortex Conguration over USB (cont.)
Option 1: Download Using VEXnet or USB
Withthisoptionselected,ROBOTCwilldownloadROBOTCrmwareandprogramstoyour
Cortex using a VEXnet or USB connection. In this mode, when the Cortex is powered ON it
will look for a VEXnet or USB connection for up to 10 seconds before running your program.
(The Automatic Selection option in the ROBOTC Preferences should be selected if you plan
on switching between VEXnet and USB as your download method.)
Option 2: Download Using USB Only
Withthisoptionselected,ROBOTCwilldownloadrmwareandprogramstoyourCortex
using only the USB connection. In this mode, when the Cortex is powered ON it will
immediately run your program. This option is NOT recommended if you are using the
VEXnet Joysticks to download to the Cortex, or remotely control it.
Option 1: Download for Competition (VEXnet)
This option disables the ROBOTC debugger, and is not recommended for classroom use.
Important Note: Restarting the Cortex
The VEX Cortex Download Method setting is stored in ROBOTC and on the Cortex. If you
change the setting, the Cortex must be power cycled (turned fully off, and then back on)
before the change will take effect.
