This article explains how to wirelessly project to either the screen of the Gym-Cart or the screen of the Lib-Cart. Since the BoxLight screen is on a wheeled-cart and the ScreenBeam does not have a network wired-connection the process is different than wirelessly projecting in other classrooms.

The Gym-Cart-SB and Lib-Cart-SB will not show as an option to Screen Mirror/Screen Cast to when connected to Overlake Open WiFi, unless the ScreenBeam has a wired-connection to the Overlake Open network. 

1) Connect the WiFi of the device (laptop, ipad, etc) that will be projecting to either the 
Gym-Cart-WiFi or Lib-Cart-WiFi. Note: the ScreenBeam on the cart must be within range of,
and connected to Overlake Open WiFi. 

2) From the device (laptop, ipad, etc) that will project, Screen Mirror/Screen Cast to the either 
Gym-Cart-SB or Lib-Cart-SB.
