ARX is provided to you in two parts, there is a client that runs on your android and ios device that you can pick up in your favorite app store and a server that is built into the Logitech Gaming Software (version 8.87.166 as of this writing) that supports the logitech gaming mice and keyboards. Both the client and server are available for free and Logitech has graciously allowed you to use the ARX software even if you do not own a Logitech gaming mouse or keyboard.
To use the ARX functionality you need to install both the LGS and phone app from above, and make sure both are running and connected together. From there simply launch the sim and we will push out a display to your phone. Inside the sim youYou can go into the options tab and under external display you will find a check box to turn ARX off and an ARX mode: dropdown that lets you choose what page to display on your phone.
